Description
Technical field
The present invention relates to a kind of bearing and its retainers.
Background technique
High-speed angular contact ball bearing can generate a large amount of heat when running at high speed, if heat dissipation is insufficient or can make axis not in time
The operating temperature held increases, and shortens bearing service life, reduces the use reliability of bearing, or even initial failure occurs.Usually
The temperature in bearing working area is reduced using the circulation of lubricating oil, but the retainer of high-speed angular contact ball bearing mainly uses at present
Circumferentially there is spaced pocket hole to be used to install rolling element for the higher entity structure of intensity, retainer, and lubricating oil, which passes through, to be kept
Gap between frame pocket hole and rolling element takes away the run at high speed heat of generation of bearing with cooling bearing, but retainer makes
Bearing interior space becomes smaller, and the area of passage that lubricating oil passes through bearing retainer is smaller, and the circulating effect of lubricating oil is poor, causes to moisten
Lubricating oil cooling effect is deteriorated, and seriously affects the normal operation performance of bearing.
Summary of the invention
The purpose of the present invention is to provide a kind of bearing and its retainers, and the cooling effect to solve the problems, such as bearing is poor.

The retainer ontology is equipped with multiple through-holes, and each through-hole is evenly arranged on the circumferential direction of retainer ontology.
The through-hole is equipped in spacer on the retainer ontology between adjacent pocket hole.
The bearing retainer is nonmetallic bearing retainer, is fixed in the through-hole strong for reinforcing retainer ontology
The reinforced pipe of degree.
The reinforced pipe and the through-hole elastic conjunction.
The technical solution of bearing of the present invention is: a kind of bearing, including bearing retainer, and the bearing retainer includes keeping
Frame ontology, axially spaced-apart is distributed with pocket hole on retainer ontology, in the spacer on the retainer ontology between adjacent pocket hole
At least one be equipped with the through-hole for passing through for lubricant medium through the axial ends face of retainer ontology.
The retainer ontology is equipped with multiple through-holes, and each through-hole is evenly arranged on the circumferential direction of retainer ontology.
The through-hole is equipped in spacer on the retainer ontology between adjacent pocket hole.
The bearing retainer is nonmetallic bearing retainer, is fixed in the through-hole strong for reinforcing retainer ontology
The reinforced pipe of degree.
The reinforced pipe and the through-hole elastic conjunction.
The beneficial effects of the present invention are: opening up axial direction at least one of spacer between the adjacent pocket hole of retainer
Through-hole, lubricant medium can be made by passing through in through-hole, the area that lubricant medium flows through bearing is increased, make following for lubricant medium
Circulation is dynamic more smooth, enhances cooling effect, improves the radiating condition of bearing, improves the service life of bearing.And
And through-hole of the invention is easy to process, retainer overall structure is simple.
Through-hole on retainer ontology is uniformly distributed, advantageously ensures that the uniform quality of retainer, keeps the dynamic balance of bearing
Energy.
It is equipped with through-hole in spacer to pass through for lubricant medium, further increases the area that lubricant medium flows through bearing,
Enhance cooling effect.
It is fixed in through-hole in order to make intensity of the non-metallic cage after opening up through-hole can continue to meet requirement
Reinforced pipe is assembled, can be improved the intensity of retainer.
Reinforced pipe and through-hole are interference fit, are capable of fixing reinforced pipe in through-hole.
