Description

A kind of retainer of roller bearing
Technical field
The utility model belongs to bearing structure field, is specifically related to a kind of cylindrical roller combination bearing that can bear larger radial and axial joint load, is mainly used in the engineering machinery such as speed reducer.
Background technique
Bearing is that one is applied on rotating mechanism, is used for supporting, and reduces friction and bears the parts of load.This product is mainly for engineering machinery such as speed reducers and designs, and owing to can bearing larger radial load and thrust load, mounting or dismounting are simple, and bearing capacity is very strong, thereby is widely used in the engineering machinery such as speed reducer.Current domestic thrust sector retainer generally adopts contact surface spheric structure, and referring to Fig. 5, Fig. 6, the retainer of this structure exists following shortcoming:
1, because contact surface is disc, therefore retainer is larger to the envelope surface of roller when bearing working, contact morely, cause that friction is large, rotating speed is low, be easy to wearing and tearing;
2, surface accuracy requirement is high, is difficult to processing;
3, retainer crossbeam end face does not have annular groove, and roller mounting or dismounting inconvenience and lubricant oil circulation are not smooth.
Model utility content
Technical problem to be solved in the utility model is to overcome existing deficiency in prior art, provide a kind of simple for structure, versatility good, it is little to rub, the retainer of the roller bearing that lubricated.
For realizing the object of the utility model, be achieved by the following technical solutions: a kind of retainer of roller bearing, described retainer entirety is ring, on retainer, evenly form multiple pocket holes that hold cylindrical roller, described pocket hole entirety is rectangular, and two walls that pocket hole coordinates with cylindrical roller are the plane being parallel to each other; The internal and external circumferential that is positioned at pocket hole on described retainer forms respectively internal ring wall and external annulus, and internal ring wall is concordant with pocket hole end surface, and external annulus is higher than pocket hole end surface; Described retainer both ends of the surface are positioned at external annulus with formation concave ring groove, and the position in one of them concave ring groove between two adjacent pocket holes forms end face groove triangular in shape; Described pocket hole forms the second confined planes near the two ends of a side of groove, and two the second confined planes coordinate the reducing shape that forms restriction cylindrical roller; The two ends that described pocket hole differs from the opposite side of the second confined planes form the first confined planes; Distance between two the first confined planes outer ends is less than two distances between the second confined planes outer end; Described retainer is by integrally moulded.
As preferred version: described concave ring groove bottom surface and internal ring wall, external annulus crossover position form the guide groove of cross section semicircular in shape.
Compared with prior art, the beneficial effects of the utility model are: two walls that described pocket hole coordinates with cylindrical roller are the plane being parallel to each other, and roller forms line with retainer working plane and contacts, and realize good heat radiating and evenly lubricated, reduce friction, ensure low vibration and quiet; Between described the second confined planes and leg-of-mutton groove, there is less thickness, possess good elasticity, be beneficial to the dismounting of cylindrical roller; Described concave ring groove bottom surface and internal ring wall, external annulus crossover position form the guide groove of cross section semicircular in shape, are convenient to lubricant oil circulation: simple in structure, highly versatile.

Embodiment
With reference to the accompanying drawings embodiment of the present utility model is made a detailed explanation below.
According to shown in Fig. 1 to Fig. 4, the retainer of a kind of roller bearing described in the present embodiment, described retainer 3 entirety are ring, on retainer, evenly form multiple pocket holes 31 that hold cylindrical roller, described pocket hole entirety is rectangular, and two walls that pocket hole coordinates with cylindrical roller are the plane being parallel to each other; The internal and external circumferential that is positioned at pocket hole on described retainer forms respectively internal ring wall and external annulus, and internal ring wall is concordant with pocket hole end surface, and external annulus is higher than pocket hole end surface; Described retainer both ends of the surface are positioned at external annulus with formation concave ring groove 32, and the position in one of them concave ring groove between two adjacent pocket holes forms end face groove triangular in shape 34; Described pocket hole forms 36, two the second confined planes of the second confined planes near the two ends of a side of groove and coordinates the reducing shape that forms restriction cylindrical roller; The two ends that described pocket hole differs from the opposite side of the second confined planes form the first confined planes 35; Distance between two the first confined planes outer ends is less than two distances between the second confined planes outer end; Described retainer is by integrally moulded.The first described confined planes, the position that the second confined planes has limited cylindrical roller, make it to be difficult for deviating from; Between described the second confined planes and groove 34, there is less thickness, possess good elasticity, be beneficial to the dismounting of cylindrical roller.Described retainer is by integrally moulded, and production and processing is convenient.
Two walls that described pocket hole coordinates with cylindrical roller are the plane being parallel to each other, pocket hole and cylindrical roller area of contact reduce, form linear contact, so just both can conveniently install and remove roller, can reduce again bearing caused friction in operation process, can solve again heat radiation and lubrication problem between cylindrical roller 2 and retainer 3, ensure high strength, the long lifetime of bearing.
Described concave ring groove bottom surface and internal ring wall, external annulus crossover position form the guide groove 33 of cross section semicircular in shape.Described retainer two sides has four guide grooves, can hold more lubricant oil, has ensured to rub between cylindrical roller and inner ring, seat ring little, and heating is few, long service life; And the weight of retainer decreases, save cost, embody economic benefit.
Be illustrated in figure 4 a combination bearing, include seat ring 1, inner ring 4 and outer ring 6, between an end face of described inner ring and the end face of seat ring, be evenly provided with cylindrical roller 2, cylindrical roller is arranged in a retainer 3; Described inner ring is away from being provided with the second roller 5 between the other end outer wall of seat ring and outer ring inwall.Cylindrical roller and the second roller are cylindrical.When this combination bearing assembling, first snap ring 7 is enclosed within on inner ring 4, with assembling mould, the second roller 5 is installed in the roller mounting groove of inner ring, then put outer ring 6, then snap ring 7 is packed into outer ring 6.Complete the installation of rotary bearing part, then thrust packs cylindrical roller 2 retainer 3 into from the second confined planes one side, and cylindrical roller is installed on after retainer, adds top race 1, realizes last trap, forms a set of bearing.
