Abstract

The invention provides a novel bearing, relating to the field of bearings. The novel bearing is characterized in that a shaft hole is formed in a bearing inner ring, wherein the bearing inner ring is arranged in a bearing outer ring, steel balls are uniformly arranged between the bearing outer ring and the bearing inner ring, a plurality of through troughs are uniformly formed in the inner wall of the bearing inner ring, oil troughs are formed in the outer wall of the bearing inner ring, and through holes are formed between the oil troughs and the through troughs. According to the novel bearing, the problem of lubrication between a shaft and a shaft hole of a motor is effectively solved, the abrasion between the shaft and the shaft hole can be effectively reduced, the total quality of a product is improved, the market competitiveness of the product is high, the noise is low in a production process, and the energy is saved.

Description

A kind of novel bearing
Technical field:
The present invention relates to field of bearings, be specifically related to a kind of novel bearing.
Background technique:
Bearing is the fixed member in machinery, when other parts produce relative movement each other on axle, be used for retainer shaft central position and control the parts of this motion.
Bearing has been widely used in the device for revolving and driving such as motor, being designed to overall structure or offering oil groove at axis hole root or part of existing bearing axis hole and axle, such design exist axle and axis hole area of contact large and cause the large and lubricated not good shortcoming of noise.At the root notching construction of axis hole, the lubricant oil being added in axis hole easily flow to motor bottom after motor rotation, not good to the fitting surface lubrication effect of axle and axis hole, easily the shortcoming of the large and noise of generation current.Along with more and more higher to the requirement of quality of product and Product Precision in recent years, the noise of bearing is large and lubrication effect is not good will directly cause the downslide of product total quality, reduce the competitiveness of product in market in addition.
Summary of the invention:
The object of this invention is to provide a kind of novel bearing, it efficiently solves the lubrication problem between motor shaft and axis hole, can effectively reduce the wearing and tearing between axle and axis hole, improved product total quality, make product more competitive on market, and noise is little in production process, and can save the energy.
In order to solve the existing problem of background technique, the present invention is by the following technical solutions: it comprises bearing outer ring 1, bearing inner race 2, axis hole 3 and steel ball 4; In bearing inner race 2, offer axis hole 3, bearing inner race 2 is arranged in bearing outer ring 1, between bearing outer ring 1 and bearing inner race 2, be evenly provided with steel ball 4, the inwall of bearing inner race 2 is evenly provided with several groove 2-1, the outer wall of bearing inner race 2 is provided with oil groove 2-2, between oil groove 2-2 and groove 2-1, is provided with through hole 2-3.
The cross section of described groove 2-1 is dovetail groove type.Be convenient to oil storage to reach better lubrication effect.
The cross section of described oil groove 2-2 is circular arc, and oil groove 2-2 runs through the outer wall of whole bearing inner race 2.The oil groove of circular arc is convenient to processing, and manufacturing efficiency is higher.
The quantity of described through hole 2-3 is 1~3.Can allow the lubricant oil in whole bearing mutually flow, improve greasy property, reduce the noise in producing, and can save power supply.
The present invention efficiently solves the lubrication problem between motor shaft and axis hole, can effectively reduce the wearing and tearing between axle and axis hole, has improved product total quality, make product more competitive on market, and in production process, noise is little, and can have saved the energy.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of middle (center) bearing inner ring 2 of the present invention.
Embodiment:
See figures.1.and.2, this concrete enforcement by the following technical solutions: it comprises bearing outer ring 1, bearing inner race 2, axis hole 3 and steel ball 4; In bearing inner race 2, offer axis hole 3, bearing inner race 2 is arranged in bearing outer ring 1, between bearing outer ring 1 and bearing inner race 2, be evenly provided with steel ball 4, the inwall of bearing inner race 2 is evenly provided with several groove 2-1, the outer wall of bearing inner race 2 is provided with oil groove 2-2, between oil groove 2-2 and groove 2-1, is provided with through hole 2-3.
The cross section of described groove 2-1 is dovetail groove type, is convenient to oil storage to reach better lubrication effect.
The cross section of described oil groove 2-2 is circular arc, and oil groove 2-2 runs through the outer wall of whole bearing inner race 2.The oil groove of circular arc is convenient to processing, and manufacturing efficiency is higher.
The quantity of described through hole 2-3 is 1~3, can allow the lubricant oil in whole bearing mutually flow, and improves greasy property, reduces the noise in producing, and can save power supply.
This concrete enforcement efficiently solves the lubrication problem between motor shaft and axis hole, can effectively reduce the wearing and tearing between axle and axis hole, has improved product total quality, make product more competitive on market, and in production process, noise is little, and can have saved the energy.
