Abstract
The utility model relates to a bearing, including a bearing seat; a shaft hole is arranged in the middle of the bearing seat; and a plurality of oil grooves are uniformly distributed on the inner wall of the shaft hole. The utility model has the beneficial effects that the oil grooves uniformly distributed on the inner wall of the shaft hole could directly reduce the friction surface between the shaft and the inner wall of the shaft hole, decrease the friction coefficient of the shaft and the shaft hole and decrease noise and current; since the oil grooves are uniformly opened towards top of the shaft hole and are arranged on the periphery of the inner wall of the shaft hole, a lubricating oil fed into the oil grooves is not easy to flow to the bottom of the motor after the motor runs so as to greatly improve the lubrication effect for a matched surface of the shaft and the shaft hole.
Description
Technical field
The utility model relates to field of mechanical technique, relates in particular to a kind of bearing.
Background technique
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 be directed at the big and lubricated not good shortcoming of noise greatly.At the root notching construction of axis hole, add lubricant oil in the axis hole easily flow to motor behind motor rotation bottom to, not good to the fitting surface lubrication effect of axle and axis hole, easily produce the big and big shortcoming of noise of electric current.In addition along with in recent years to more and more higher today of requirement of quality of product and product precision, the noise of bearing is big and lubrication effect is not good will directly cause the downslide of the total quality of product, the reduction competitiveness of product in market.
The model utility content
The purpose of this utility model provides a kind of bearing, with the oil groove opening in the axis hole towards the bearing top design.Effectively solve the motor shaft and the lubrication problem of axis hole of this type, can effectively reduce wearing and tearing and the effective reduction running noise of motor and the electric current of axle and axis hole.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of bearing comprises bearing support, and the middle part of described bearing support is provided with axis hole, and some oil grooves evenly distribute on the inwall of axis hole.
The beneficial effects of the utility model are: can directly reduce the axle and the mill sassafras face of shaft hole inner wall owing to have oil groove uniformly at shaft hole inner wall, reduce the mill sassafras coefficient of axle and axis hole, minimizing noise and electric current.Again because its oil groove is around uniformly being opened in the inwall of axis hole towards the axis hole open top, add lubricant oil in the oil groove is difficult for flowing to motor behind motor rotation bottom to, the fitting surface lubrication effect of axle and axis hole is promoted greatly.
Description of drawings
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the structural representation of the described a kind of bearing of the utility model embodiment.
Among the figure:
1, bearing support; 2, axis hole; 3, oil groove.
Embodiment
As shown in Figure 1, the described a kind of bearing of the utility model embodiment comprises bearing support 1, and the middle part of described bearing support 1 is provided with axis hole 2, and some oil grooves 3 evenly distribute on the inwall of axis hole 2.
After axle is installed in axis hole 2, inject lubricant oil in some oil grooves 3 around the inwall of this axis hole 2, can directly reduce the axle and the mill sassafras face of axis hole 2 inwalls owing to have oil groove 3 uniformly, reduce the mill sassafras coefficient of axle and axis hole 2, minimizing noise and electric current at axis hole 2 inwalls.Again because its oil groove 3 is around uniformly being opened in the inwall of axis hole 2 towards axis hole 2 open tops, and institute adds oil groove 3 interior lubricant oil are difficult for flowing to motor behind motor rotation bottom to, the fitting surface lubrication effect of axle and axis hole 2 is promoted greatly.
Claims (1)
1. a bearing comprises bearing support (1), it is characterized in that: the middle part of described bearing support (1) is provided with axis hole (2), and some oil grooves (3) evenly distribute on the inwall of axis hole (2).
