Abstract
A novel bearing relates to the bearing field. A shaft hole is disposed in the inner ring of the bearing; the bearing inner ring is disposed in the bearing outer ring; steel balls are uniformly disposed between the bearing outer rings and the bearing inner rings; a plurality of through grooves are uniformly disposed on the inner wall of the bearing inner ring; an oil groove is disposed on the outer wall of the bearing inner ring; a through hole is disposed between the oil groove and one of the through grooves. The novel bearing effectively solves the lubrication problem between a motor shaft and the shaft hole, effectively reduces abrasion between the shaft and the shaft hole, improves integral product quality, provides more market competitiveness for the product; and the production process is low in noise, and saves energy.
Description
Technical field:
The utility model relates to field of bearings, is specifically related to a kind of novel bearing.
Background technique:
Bearing is the fixed member in the machinery, when other parts produce relative movement each other on axle, be used for retainer shaft the central position and control the parts of this motion.
Bearing has been widely used in the device for revolving and driving such as motor, the existing bearing axis hole is designed to overall structure or offers oil groove at axis hole root or part with axle, and such design exists axle and axis hole area of contact to cause the big and lubricated not good shortcoming of noise greatly.At the root notching construction of axis hole, the lubricant oil that is added in the axis hole easily flow to motor bottom behind motor rotation, and is not good to the fitting surface lubrication effect of axle and axis hole, easily produces electric current greatly and the shortcoming of noise.Along with more and more higher to the requirement of quality of product and product precision in recent years, the noise of bearing is big and lubrication effect is not good will directly cause the downslide of product total quality, reduce the competitiveness of product in market in addition.
The model utility content:
The purpose of this utility model provides a kind of novel bearing, it efficiently solves the lubrication problem between motor shaft and the axis hole, can effectively reduce the wearing and tearing between axle and the axis hole, improved the product total quality, make product more competitive on market, and noise is little in the production process, and can save the energy.
In order to solve the existing problem of background technique, the utility model is by the following technical solutions: it comprises bearing outer ring 1, bearing inner race 2, axis hole 3 and steel ball 4; Offer axis hole 3 in the bearing inner race 2, bearing inner race 2 is arranged in the bearing outer ring 1, evenly be provided with steel ball 4 between bearing outer ring 1 and the bearing inner race 2, the inwall of bearing inner race 2 evenly is provided with several grooves 2-1, the outer wall of bearing inner race 2 is provided with oil groove 2-2, is provided with through hole 2-3 between oil groove 2-2 and the groove 2-1.
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 interior lubricant oil of whole bearing flow mutually, improve greasy property, reduce the noise in producing, and the energy conserver power source.
The utility model efficiently solves the lubrication problem between motor shaft and the axis hole, can effectively reduce the wearing and tearing between axle and the axis hole, has improved the product total quality, make product more competitive on market, and noise is little in the production process, and can have saved the energy.
Description of drawings:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model middle (center) bearing inner ring 2.
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; Offer axis hole 3 in the bearing inner race 2, bearing inner race 2 is arranged in the bearing outer ring 1, evenly be provided with steel ball 4 between bearing outer ring 1 and the bearing inner race 2, the inwall of bearing inner race 2 evenly is provided with several grooves 2-1, the outer wall of bearing inner race 2 is provided with oil groove 2-2, is provided with through hole 2-3 between oil groove 2-2 and the groove 2-1.
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 interior lubricant oil of whole bearing flow mutually, improves greasy property, reduces the noise in producing, and the energy conserver power source.
This concrete lubrication problem of implementing to efficiently solve between motor shaft and the axis hole can effectively reduce the wearing and tearing between axle and the axis hole, has improved the product total quality, make product more competitive on market, and noise is little in the production process, and can have saved the energy.
