Abstract
The invention relates to a motor bearing end cover. The motor bearing end cover comprises a cover body. The cover body is provided with a shaft hole for fixing the spindle. The shaft hole is provided with an oil supply tank. The oil supply tank is provided with an oil supply hole. The upper end of the oil supply hole is provided with a screw. A U-shaped groove is formed in the inner side of the cover body. According to the invention, by arranging the lubricating tank provided with the oil supply hole, oil supply can be performed on the spindle timely and conveniently so as to reduce the frication, and by arranging the screw, more lubricating oil can be stored so as to prolong the lubricating time to prolong the service life of the spindle. Moreover, advantages of simple structure, convenient operation, economy and practicability can be realized.
Description
Technical field
The present invention relates to technical field of motors, relate in particular to a kind of motor bearing end cover.
Background technology
Motor bearing end cover is mainly for bearing is installed, and then guarantees the vitals that axle runs well.Electric motor end cap is the lid that limit is contained in motor case two ends, be commonly called as end cap, the major function of end cap is to lay rotor bearing, general motor, the rotor external force that bearing bears when high speed rotating is mainly radial load, so just passable with a common ball bearing, but the motor that some is special, as the motor of electric drill, it not only will make drilling rod rotate, but also to give one, drilling rod thrust forward, the bearing of such rotor is bearing axial pressure, need to after common ball bearing, install an angular contact thrust bearing additional, so, electric motor end cap originally just cannot adapt to this special needs.Yet, on existing motor bearing end cover, lacking for lubricating arrangement, this is unfavorable for the lubricated of rotating shaft, and then affect the normal operation of axle, the motor bearing end cover also having lacks lubricating oil storage device, and this is unfavorable for long-time fuel feeding, can not meet real Production requirement.
Summary of the invention
The object of the invention is, in order to overcome the deficiencies in the prior art, provides a kind of motor bearing end cover.
The present invention is achieved through the following technical solutions:
A motor bearing end cover, comprises lid, and described lid is provided with the axis hole of fixed electrical machinery rotating shaft, and described axis hole is provided with oil supply tank, described oil supply tank be provided with oil supplying hole, described oil supplying hole upper end is provided with screw.
As the preferred technical solution of the present invention, the inner side of described lid is provided with U-lag.
As the preferred technical solution of the present invention, the shape layers half elliptic of described oil supply tank, the major axis of oil supply tank be 1mm between 2mm, the minor axis of oil supply tank is that 0.5mm is between 1.5mm.
As the preferred technical solution of the present invention, described oil supply tank has several, and the distance of adjacent oil supply tank is that 1.5mm is between 3mm.
As the preferred technical solution of the present invention, the radius of described oil supplying hole is that 2mm is between 4mm.
During on-the-spot use, first, operating personnel install the present invention in place, rotating shaft is arranged in axis hole, then screw is screwed out, and lubricating oil is added in oil supplying hole, and lubricating oil enters in lubrication groove through oil supplying hole, can countershaft fuel feeding.
Compared with prior art, the invention has the beneficial effects as follows: the present invention contributes to timely countershaft to carry out fuel feeding by being provided with the lubrication groove of oil supplying hole, contribute to reduce friction, by screw is set, contribute to store more lubricating oil, contribute to extend lubrication time, improve the life-span of rotating shaft.And simple in structure, easy to operate, economical and practical.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
