TITLE- Hardening.of Hub-carrying Sections of Shafts byMeana of Burnishing With Rollers and the Strength of Forced Fits Under the Action of Cyclic Loading (Uprochneniye podstupichnykh chastey valov obkatkoy rolikami i prochnose pressovykh soyedineniy pri povtorno- peremennoy n,agruzke) PERIODICAL: V ob.. Povysheniye dolgovechnosti mashin. Moscow, Mashgiz, 1956, pp 134-150 ABSTRACT- The strength (S) of a force.-fit connection (FF) under the action of an axially applied cyclic loading (L) was investigated on a shaft of normalizedgrade-40 steel which had been roll-burnished with a three-roller device under -a pressure of 50 kg and had then been press fitted to the bushing of a ball bearing. In the case of pulsating cycles, as well as cycles with large amplitudes, the destruction of a FF occurs under the action of a total cyclic L which is twice -as great as the force required in assembling the components. This circum- Card 1/2 stance demonstrates the impossibility of plotting a function of the SOV/137-57- 1-1100 Hardening of Hub-carrying Sections of Shafts by Means of Burnishing (cont.) fatigue curve and Indicates that the cyclic S of FF's subjected to axial L in compa- rable to the static S. Alternating symmetrical torsion was employed In testingof roll-burnished and ground specimens of steel 40 and specimens of a steelcontain- Ing 1 .2% C which had been machined only. On the strength of the investigations performed the only criterion that could be established was a safe limit of cyclic L below which the FF's -are not disrupted. 'Under conditions of the combined action of bending and torsional stresses, the endurance of roll-burnished speci- mens exceeds that of polished specimens by 70fe. Roll-burnished specimens were subjected to alternating -bending pretreatment, wherein they were gubjected to stresses of IZ-22 kg/rnmf-, the number of cycles amounting to 30x 10 - A resonant-frequency fatigue-testing machine was employed to provide alternating torsion loading for the FF's. Experience shows that the resistance of specimens to cyclic torsion Is significantly increased as a result of such preliminary bend- ing treatment which accomplishes a relief of residual stresses arising in the surface layer during roll - burnishing. Compared with ground surfaces, roll- burnishing of specimens increased their endurance limit by a factor of Z.5. Hard- ening of the hub-carrying sections of shafts by means of roll-burnishing with rollers does not impair the S of a FF between a shaft and a bushing under cyclic as well as under static L.

A simple method is described constituting a supplementation of the study of residual stresses (RS) by the Sachs method, making it possible to employ the latter in the absence of highly- sensitive measuring instruments to measure small deforma- tions (D) arising in a product as layers of metal are removed. The instrument needed to make use of this method consists of an ordinary micrometer and a press with a dynamometer or a machine for static tomion testing. The method consists of em- ploying a shrunk-on ring as an indicator of the D in a cylinder containing RS and subject to tension. As the shrunk-on ring Card 1/3 (SR) makes it possible to determine the diametral D of the 137-58-1-2001 Measuring Strains by Means of a Shrunk-on Ring (cont. cylinder only, this method is suited to the study of tangential and radial RS In cylinders of small height. namely, disks. This method is based on the difference In the nature of change in the strength in shrunk-on joints con- sisting of a SR and a cylinder being machined layer by layer, in cases In which the cylinder does and does not have RS. Calculated expressions are presented for computations of the magnitude of the relative tangential D in re- lation to the change In the strength of the seating of the SR on the disk when RS are removed by boring. An expetimental check is presented of the method of employment of a SR for cases In which the strength of seating of a -ring is measured by pressure-relief expansion and by torsion. When a SR is shrunk on to a disk, the seating surfaces of the disk and the SR are lubricated with machine lubricant. It is shown that to avoid skewing and scoring of seating surfaces. the shrinking of the disk into the ring should be done in a guide sleeve. The rate of shrinking-in shoald be constant for all pairs of disks in the SR and should not exceed 10mm/rnin. Shrinking-on should be tAccompanied by a recording of the shrink-on diagram and of the maximum shrinkage stress. After shrinking-on, the joints should be set aside for not less than two days. The method and experimental results of studies of RS in steel shafts strength- ened by peripheral rolling are presented.

(Conte) residual stresses from compressive stresses in the hardened layer to tensile after tempering at a tempera- ture of intensive martansite decomposition was observed, as was observed by other authors for medium carbon steels. If tempering: is carried out in this temperature range, the residual stresses in the transient zone directly below thebArdened layer also change and the originally tensile residual stresues change into compressive stresses. Such re-distribution of the residual stresses is local in character and encompasses only the hardened layer and the transient zone. The characteristic of the stress spurs does not change outside these zones and the level of the residual stresses decreases with increasing temperingtemperatures. The residual compressive stresses which form in the zone directly below the surface hardened layer apparently bring about some increase in the fatigue strength of components tempered at 300 to 400"C. the destruction of which is initiated by the formation of cracks in the transient zone. 1 Table, 3 Graphs; one German and seven Russian references.

ABSTRACT: In the present context, eccentric holes means holes on a circle concentric with the axle of the wheel, as distinct from a central hole through which the axle passes. Eccentric holes are very dangerous in a rotating disc because of local stress concentrations. In the plane-stressed state that is set up in such adisc, the most highly-stressed parts are the zones near points A and B, on the edges of the eccentric holes, as shown in Figure 1. In these zones, one of the principal stresaea (tangential or radial) is nearly zero and the other is at a maximum. Since the theoretical concentrations have been shown by a previous work to be very high, it was necessary to study the actual influence of 'eccentric holes on the strength of rotating discs experimentally by making destruotive overspeed tests. Previous work has shown that the presence of eccentric holes in discs of brittle heat-resiatant material causes considerable reduction in the strength but c r gagin ing data for discs of plastic alloy steels are not 7; d Ca 0* r3r SOV/96-58-5-4/27 Overspeed Toots on Rotating Discs with Eccentric Hole Arrangement This article dosaribes results obtained In the ToNI17MM (Scientific Research Institute of Engineering Technology) during-an wtporimental, Investigation of the actual Influence of eccentric holes on the failure of rotating dines of improved plastic steelp 34KhN3M.

Finally) the results of overspeed tests were used to armayso the nature of the failures according to the ratio of the radial and tangential stresses In the zone near the holes.

The disco were classified Into three groups depending on the ratio of the radial and tangential stresses along the radius. Stress distrIbution diagrams relating to each or the three groups are drawn In Figure .3. These diagrams are constructed for a nominal speed of 18,000 rpm. An approximate index of the nature of the stress conditions of the disc is the ratio of the radial to the UqontW stress taken from the ctrees diagra= or Figure 1 for disco without eccentric holes. k1togethor 10 Mmoizw= wore tested. The nechanical proper- ties of the material for each are given In Table 1. The resistance to failure of the disco " the radial and tangential stresses at failure were calculated from the speed at railure. The theory of elasticity furnished only Card 3/5 SOV/96-58-5-4/27 Overapeod-Tests on Rotating Discs with Iccentric Hole Arrangement approximate calculations because it ignores stress re- distribution beyond the elastic limit at the moment of failure but the calculations are sufficiently accurate for our purpose. The results of overspeed tests are given in Table 2; the types of failure can be soon from the photographs in Figures 4 - 8 and are discussed. Examination of the data in Table 2 for discs with and without eccentric holes shows that in our tests unlike American istan, tests in discs of brittle beat-res t material, the presence of eccentric holes does not reduce the resistance to failure of rotating discs. As in the previous work on discs with keyways this is associated with the good plastic properties of steei 34IMM within the limits of the com- parativelysmall turbine discs used for model testing. In practice, of course, discs will be larger and the plasticity will be affected by forging. There was fairly good agreement between the mean tangential stress and vne tensile strength of discs that failed on the radial section due to tangential astresses and those that Card 4/5 SOV/96-58-5-4/27 Overspeed Tests on Rotating Discs with Eccentric Hole Arrangement failed on annular sections due to radial stresses. This was unexpected and a brief explanation is offered. As will be seen from Figure 8, in the zone near the hole there is appreciable local constriction of the disc by tangential stresses, which shows that when the disc fails under radial stress the tangential stress is at that instant also near the ultimate strength. Finally, the data in Table 2 shows that cold working of the holes has no influence on the strength of the disc and is accordingly deprecated.

A formula is given for the loosening-speed based on the assumption that at this speed the radial stress on the bore is zero. The author bas observed that contrary to the general belief . during over- spoed testing of turbines the loosening-speed of the disco may be much higher than the calculated value. loosening-speed tests were made on models as Illustrated in Fit,.L One Lad two diametrically-opposite rectangular key*ays; anotber bad none. The disco were nade of steel 32 XH311 I %`be =ecbanical properties of which are given, and were shrunk oji to a abaft 50 mr. dia. , illustrated in Fig. 21 with an interference of 0-03 - 0-06 as.- They were press-fitted, the pres%3ing diabrams being recorded. The mating surfaces of the disc and sbaft were ground and lubricated with machine oil. Overspeed tests on the discs were Cardl/4 made on the equipment described in a previous article in On the Loosening-speed of Discs with Keyways. 96-1-9/31 Moploeaergetika, 19579 No-7- Runs were made at different speeds and loosening was recognised by arWular displacement of the disc on thp shaft. The distribution of radial and tangential stresses wi-on the model is rotated at 18 000 r.p.m. is illus- trated in 7ig-3. The measurements and the calculated loosening- speeds are tabulated, showing good aCreement for discs without keyways but discrepancies for those with two diametrically- opposite keyways which became looseonly at a speed ofl.8 - 2.3 times the calculated value. This was at first attributed to distortion of the abaft, which was supposed to be swelling into the keyway as shown in Fig. 4A; but this sugPosition was disproved. It was, however, observed that when t e disc was pressed onto the shaft it became trapezoidal in shape. Defor- mation observations were made on other discs with keyways, one of which was additionally fixed to the shaft by thin strips of low ri idity.

TITLE:Retarded Failure of the Reinforcing Rings of the Supp*rting Rolle of Cold Rolling Stands (Zanedlennoye razrushoniye bandazhey opornykh valkov kholodnoy prokatki) PERIODICAL: Metallovedeniye I Obrabotka Metallov, 1958,Nr 5, VP 43-48 (USSR) ABSTRACT: In addition to known types or failures of rolls, there have been cases of brittle cracking of the reinforcing rings as a result of which a brittle fracture occurs in the tubular reinforcing rings which were tightly (shrink) fitted on the backing roll; the fracture was orientated in the direction of the generatrix. The fractured reinforcing rings consisted of 2000 mm long tubes with an outside diameter of about 1600 mm and 800 innide diameter produced from 9Kh type steel with vanadium which,after annealin6,was subjected to further' heat treatment by repetitivo hardening In viateg and in oil. The hardened rings were tempered at 400 0 so as to obtain the required hardness of 60 to 75 Shore units.

The composition of the investigated steel zas: 0.85% 0 1 0.32% Mn, 0.28% Si, 0.018% S, 0.02?% P and 1.59% Or. flotchod specimens (PI-Pure 2) wore used which wore subjected to static tension. The specimens were cut from 18 mm Sia. rods, heated for th.~oe minutes in a salt bath to 830 C and hardened in oil. Th1s wac gollowed by tempering for three holars at 150, 400 ond 730 C and cooling in the furnace, The tendency of the materinl to slow failure wan determined in three sta&ou. At first the stronirth acr of notched sp..jelmens was determined b for ordinary short duration tests, ostabli:~hing for.oach type of heat treatment the appearance of the fracture, the character of the obtained liagram, the transverso contraction in the notch after fracture and the degree of sciatterine or the obta:Lned valuez.

The authors also suggest a now combined method 'of determining the residual strosseep which consists In introducing a correction Into -the curve of the dependence of the change In the -respective deformation 6 or 6 upon the variable -sur- face 7 of the ground and treated cylinder (disk). The Introduction of -the correction permits calculation of the residual stresses both from the separated (for the sections of the preceding and final cutting) and from Card 1/3 Deformation Correction and the Precise 3/032/60/026/012/019/036 Representation of the Dthlor Method of Direct B020/B056 Determination of Residual Stresses Ingle relations (for grinding and treating along the entire ra41us). The : uggested Introduction of the correction is demonstrated on the basis of the calculation of residual stresses In a disk from the relations mentioned. For the introduction of corrections for -the deformation measured in the final stage of cutting# the final extent of the defornationt determined after the preceding grinding or treatment has been carried outq is used.
