Description
Technical field
The utility model is related to a kind of bearing needle.
Background technology
Bearing needle is the important component in bearing, and usual needle roller is arranged on retainer, and retainer is used to separate each
Needle roller, keeps needle roller spacing equal, makes load mean allocation, and bearing needle turns between bearing inner race and bearing outer ring when using
Move so as to realize the function that bearing inner race and outer ring mutually rotate.Because bearing needle needs constantly to be rubbed with bearing inner race and outer ring
Wipe, therefore easily produce heat and be difficult to radiate, especially bearing needle and inner ring and outer ring contact position.While existing needle roller
Also there is serious wear, scrappage is high.
Utility model content
The purpose of this utility model is to provide a kind of bearing needle, and the setting of thermal vias effectively improves the radiating of needle roller
Effect, it is to avoid heat build-up；The setting of wear-resistant block can improve the anti-wear performance of needle roller, improve the service life of needle roller；Lubrication
The setting of groove can store lubricating oil, reduce needle roller and inner ring or outer ring frictionally damage.
In order to achieve the above object, the technical solution of the utility model is：
A kind of bearing needle, including needle roller body, the needle roller body upper end are connected with the first needle roller clamping boss, described
Needle roller body lower end is connected with the second needle roller screens projection, first level radiating is offered on the first needle roller clamping boss logical
Hole, the second horizontal thermal vias are offered on the second needle roller screens projection；Offered respectively on described this body sidewall of needle roller
First wear-resistant block storage groove, the second wear-resistant block storage groove, are provided with first wear-resisting in the first wear-resistant block storage groove
Block, the second wear-resistant block is provided with the second wear-resistant block storage groove；The first wear-resistant block storage groove is wear-resisting with second
Lubrication groove is offered on needle roller this body sidewall between block storage groove.
The needle roller body and the first needle roller clamping boss is integrally manufactured forms, the needle roller body and the second needle roller screens
Projection is integrally manufactured to be formed.
The first wear-resistant block that first wear-resistant block is made for cermet, second wear-resistant block is made up of cermet
The second wear-resistant block.
The first groove is offered on the wall of the first needle roller clamping boss side, is opened on the second needle roller screens nub side wall
It is provided with the second groove.
The beneficial effects of the utility model are：A kind of bearing needle, the setting of thermal vias effectively improves the radiating of needle roller
Effect, it is to avoid heat build-up；The setting of wear-resistant block can improve the anti-wear performance of needle roller, improve the service life of needle roller；Lubrication
The setting of groove can store lubricating oil, reduce needle roller and inner ring or outer ring frictionally damage.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
Embodiment 1
A kind of bearing needle as shown in Figure 1, including needle roller body 1, the upper end of needle roller body 1 are convex with the first needle roller screens
Platform 2 is connected, and the lower end of needle roller body 1 is connected with the second needle roller screens projection 3, is opened up on the first needle roller clamping boss 2
There are first level thermal vias 4, the second horizontal thermal vias 5 are offered on the second needle roller screens projection 3；The needle roller sheet
The first wear-resistant block storage groove 6, the second wear-resistant block storage groove 7, the first wear-resistant block storage are offered on the side wall of body 1 respectively
First wear-resistant block 8 is installed in groove 6, second wear-resistant block 9 is installed in the second wear-resistant block storage groove 7；Described first
Lubrication groove 10 is offered on the side wall of needle roller body 1 between wear-resistant block storage groove 6 and second wear-resistant block storage groove 7.
The needle roller clamping boss 2 of the needle roller body 1 and first is integrally manufactured to be formed, the needle roller of the needle roller body 1 and second
Screens projection 3 is integrally manufactured to be formed.
The first wear-resistant block that first wear-resistant block 8 is made for cermet, second wear-resistant block 9 is cermet system
Into the second wear-resistant block.
The first groove 11, the side wall of the second needle roller screens projection 3 are offered on the side wall of first needle roller clamping boss 2
On offer the second groove 12.The setting of the first groove 11 and the second groove 12 can avoid first level thermal vias 4 and
Two horizontal thermal vias 5 are blocked, it is impossible to radiating in time.
A kind of bearing needle of the present embodiment, the setting of thermal vias effectively improves the radiating effect of needle roller, it is to avoid heat
Pile up；The setting of wear-resistant block can improve the anti-wear performance of needle roller, improve the service life of needle roller；The setting of lubrication groove can
Storage lubricating oil, reduces needle roller and inner ring or outer ring frictionally damage.
