Abstract
An integral retainer with three rows of cylindrical roller turntable bearings comprises an annular retainer body, the retainer body is provided with rectangular through holes penetrating through the side surface of the retainer body for mounting cylindrical rollers, and two sides vertical to the radial direction of the retainer body in the rectangular through holes respectively extend along the retainer body by a section to form a circle of axial flanges. An integral retainer structure is adopted, and overcomes the problem that the existing sectional retainer has poor effect in correcting a skew effect of the rollers. Movement performance of the rollers in the three rows of cylindrical roller turntable bearings is improved by such design, and reliability of the retainer is improved. The integral retainer with three rows of cylindrical roller turntable bearings adopts the integral retainer structure, and overcomes the problem that the existing sectional retainer has poor effect in correcting a skew effect of the rollers; the retain is made of a carbon steel material and the problem of poor mechanical physical property of the existing cast aluminum ally retainer is overcome.
Description
Technical field
The present invention relates to a kind of turntable bearing device, especially relate to a kind of Integral retainer of three-row cylinder roller turntable bearing.
Background technique
Turntable bearing is used in the swirl gear of the mechanical systems such as portal crane, wind-driven generator, shield excavation machine, bucket wheel excavator, ladle turret, subjects the synergy of radial load, thrust load and tilting moment load when host work.Three-row cylinder roller turntable bearing has that bearing capacity is strong, rigidity is high and the running accuracy of axis and radial direction is easy to the advantages such as control separately, is the common structure form in practical implementation.
Three-row cylinder roller turntable bearing in the running, the revolution speed of outboard roller end is less than the revolution speed of interior survey roller end, this will cause the crooked of roller, the effect of retainer is in normal position by forcing the slip of outboard roller to maintain roller, therefore, retainer bears the effect of roller load in turntable bearing.Existing three-row cylinder roller turntable bearing mainly adopts segmented cast aluminium alloy retainer, and this retainer has two deficiencys: first segmentation structure is not so good as Integral retainer in correction roller deflection; It two is that the intensity of cast aluminium alloy material and hardness are lower, and mechanical property can not show a candle to carbon steel.
Segmented cast aluminium alloy retainer often occurs that in engineering reality retainer ruptures, and cause that the wide-angle of roller is crooked further, turntable bearing friction torque increases severely and heating, until turntable bearing lost efficacy, to such an extent as to brings tremendous economic to lose.
Summary of the invention
The object of the invention is in engineering reality, often to occur that retainer ruptures for solving upper segmented cast aluminium alloy retainer, and cause that the wide-angle of roller is crooked further, turntable bearing friction torque increases severely and heating, until turntable bearing lost efficacy, to such an extent as to the problem bringing tremendous economic to lose, a kind of Integral retainer of three-row cylinder roller turntable bearing is provided.
The present invention is the deficiency solved the problems of the technologies described above, and the technological scheme adopted is:
A kind of Integral retainer of three-row cylinder roller turntable bearing, comprise circular retainer body, described retainer body offers and runs through its side for installing the rectangular through-hole of cylindrical roller, rectangular through-hole is provided with multiple and along the even circumferential distribution of retainer body so that kept apart uniformly by cylindrical roller and avoid the sliding friction between adjacent cylindrical roller to retrain roller crooked, in described rectangular through-hole, the dual-side of vertical retainer body radial direction forms a circle axial ledge so that the location of retainer in described turntable bearing raceway die cavity along retainer body shaft to respectively extending one section, gap is provided with between the inner cylindrical surface of described axial ledge and retainer body and external cylindrical surface, to avoid the sliding friction between the circular radial cylinder of raceway die cavity.
The top of described axial ledge offers multiple groove along retainer body circumference uniform distribution.
The invention has the beneficial effects as follows: this patent is for solving the Structure Designing Problem of three-row cylinder roller turntable bearing retainer.By adopting all-in-one-piece retainer structure, overcome existing sectional type retainer correction roller deflection in the poor problem of effect; Retainer material selection carbon steel, overcomes the intensity of existing cast aluminium alloy retainer and the poor problem of hardness.Improved the exercise performance of roller in three-row cylinder roller turntable bearing by design rectangular through-hole and groove, improve the reliability of retainer.The Integral retainer of three-row cylinder roller turntable bearing of the present invention, adopts all-in-one-piece retainer structure, overcome existing sectional type retainer correction roller deflection in the poor problem of effect; Retainer material selection carbon steel, overcomes the problem that the mechanical property of existing cast aluminium alloy retainer is poor.

Graphical indicia: 1, retainer body; 101, rectangular through-hole; 102, axial ledge; 103, groove.
Embodiment
Shown in Fig. 1-3, embodiment is as follows:
A kind of Integral retainer of three-row cylinder roller turntable bearing, comprise circular retainer body 1, described retainer body 1 offers and runs through its side for installing the rectangular through-hole 101 of cylindrical roller, rectangular through-hole 101 is provided with multiple and along the even circumferential distribution of retainer body 1 so that kept apart uniformly by cylindrical roller and avoid the sliding friction between adjacent cylindrical roller to retrain roller crooked, in described rectangular through-hole 101, the dual-side of vertical retainer body 1 radial direction forms a circle axial ledge 102 so that the location of retainer in described turntable bearing raceway die cavity along retainer body shaft to respectively extending one section, gap is provided with between the inner cylindrical surface of described axial ledge 102 and retainer body 1 and external cylindrical surface, to avoid the sliding friction between the circular radial cylinder of raceway die cavity.
The top of described axial ledge 102 offers multiple groove 103 along retainer body circumference uniform distribution.
As shown in Figure 1, the Integral retainer structure of three-row cylinder roller turntable bearing of the present invention, solves existing three-row cylinder roller turntable bearing segmented cast aluminium alloy retainer and corrects roller deflection aspect weak effect, the problem that strength reliability is low.
Described Integral retainer is circle structure, as shown in Figure 1, toroidal surface being provided with some rectangular through-hole, for installing cylindrical roller, and being kept apart uniformly by cylindrical roller, avoid the sliding friction between adjacent roller, retrains the crooked of roller.
Described Integral retainer is provided with axial ledge everywhere, as shown in Figure 2, with the location of retainer in raceway die cavity.All maintain a certain distance between the axial ledge of retainer and the inside and outside cylndrical surface of retainer, avoid the sliding friction between raceway die cavity circular radial cylinder.
The axial ledge of retainer is provided with the groove that several are uniformly distributed along the circumference, and as shown in Figure 3, groove for reducing the surface of contact between axial ledge and raceway, and stores lubricating grease, thus reduces sliding friction between the two.
Technological scheme cited by the present invention and mode of execution be not restriction, be equal to the technological scheme cited by the present invention and mode of execution or effect same approach all in the scope that the present invention protects.
