Abstract
The utility model relates to a nylon cage of a cylindrical roller bearing, which can be used for compensating deformation and is guided by a roller. The circumference of the nylon cage of a cylindrical roller bearing is uniformly distributed with pockets 5, an inner margin 1 is connected with an outer margin 2 by a pocket cross beam 3, a pocket wall 4 between both the sides of the cross beam 3 is in a concave arc shape, and the center D of the pockets 5 and the center C of the roller have a displacement d to compensate the variation of the expansion and contraction of the cage when the bearing runs. The utility model has the advantages of reasonable structure, small abrasion, wide range of application, excellent performance, long service life of the cage and the bearing, etc.
Description
The utility model product relates to a kind of bearing nylon cages, especially a kind of roller bearing nylon cages that compensates distortion.
China Patent No. 88213600.3, name are called the patent of " cylinder roller bearing retainer ", although it has overcome existing solid cage and pressing cage structure limitation of design and has made defectives such as loaded down with trivial details, that cost is high, the life-span is low, noise and vibration is big, but because the pocket hole wall surface in the middle of the crossbeam both sides, retainer pocket hole is a flat face, the frictional force between bearing roller and retainer pocket hole is difficult for forming the hydrodynamic lubrication oil film, so still can not drop to minimum level.Again because reasons in structure is restricted its applicability in the roller bearing of different model.In addition, its guidance mode can only be the race ring lip-guided usually, so increased the friction of bearing operation and the accuracy of manufacturing of the interior external diameter of retainer.
The purpose of this utility model is to avoid above shortcomings in the prior art, and provides a kind of compensation distortion, longer service life, the better retainer of performance.
The purpose that the utility model proposed can be achieved through the following technical solutions: pocket hole wall, its surface design in the middle of the crossbeam both sides, retainer pocket hole become concave arc shape, like this, make retainer leave enough shifting amount, and be beneficial to formation hydrodynamic lubrication oil film, to reduce the frictional force between bearing roller and the retainer pocket hole.Simultaneously, there is a displacement amount at center, retainer pocket hole and bearing roller center, the harmomegathus amount of retainer during with compensating shaft acknowledgement of consignment row.
Description of drawings is as follows:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is an A-A sectional view of the present utility model.
Following the utility model will be further described by embodiment.
Referring to Fig. 1, Fig. 2, this retainer is made up of inner side edge 1, external side brim 2 and pocket hole crossbeam 3, and inside and outside lateral margin 1,2 is connected by pocket hole crossbeam 3, and the centre of crossbeam 3 both sides, pocket hole is a pocket hole wall 4, and the concave arc shape that it is surperficial is beneficial to form the hydrodynamic lubrication oil film.Arc shaped surface and pocket hole crossbeam 3 bodies constitute two intersection point A and B, these 2 fore shafts that just form pocket hole 5, between lock point A and external diameter apart from a for ease of pack into pocket hole 5 and form suitable hold depth and design of roller; Distance between lock point B and internal diameter should satisfy roller packs into spry and light and stops roller to be deviate from, and increases retainer intensity.The center D in retainer pocket hole 5 and bearing roller center C have a displacement amount d, and this is thermal effect and a chemical effect of considering bearing when operation roller centre and center, retainer pocket hole, the variable quantity during promptly in order to compensation bearing high speed operation after the retainer harmomegathus.This retainer injection molded of Reinforced Nylon.
The utlity model has China Patent No. 882136003 retainers simple in structure, easily manufactured, yield rate is high, save the energy, intensity height, the advantage such as anticorrosive, simultaneously, structure of the present utility model is more reasonable, and performance is better, and the scope of application is bigger. Because the surface of pocket hole wall is arcs of recesses, be beneficial to form the hydrodynamic lubrication oil film, reduce the wearing and tearing between roller and pocket hole, performance and life-span have been improved, and because center, pocket hole and roller centre have a displacement, when having compensated the bearing high-speed cruising retainer rise, the contracting variable quantity, improved the dependability of retainer and bearing, have obvious economic benefit and social benefit.
Claims (1)
1, a kind of cylinder roller bearing retainer, be evenly equipped with pocket hole 5 on the circumference, connect with pocket hole crossbeam 3 between inner side edge 1 and the external side brim 2, it is characterized in that: the pocket hole wall 4 in the middle of crossbeam 3 both sides, pocket hole is concave arc shape, and pocket hole 5 center D and roller centre C have a displacement amount d.
