Abstract

The utility model relates to a motor bearing end cap. The end cap comprises a cap body. A shaft hole for fixing a motor shaft is arranged in the cap body. Oil feeding grooves are arranged in the shaft hole, and an oil feeding hole is arranged on the oil feeding grooves. A screw is installed in the upper end of the oil feeding hole. A U-shaped groove is arranged in the inner side of the cap body. Arrangement of the lubricant grooves with the oil feeding hole facilitates feeding oil to the motor shaft in time and reducing friction. Arrangement of the screw facilitates storing more lubricant oil and extending lubricant time to extend the life of the motor shaft. Besides, the end cap is economic and practical with a simple structure and easy operation.

Description

A kind of motor bearing end cover
Technical field
The utility model relates to technical field of motors, relates in particular to a kind of motor bearing end cover.
Background technology
Motor bearing end cover is mainly for bearing is installed, and then ensures 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 in the time of 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.But, 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 purpose of this utility model is in order to overcome the deficiencies in the prior art, and a kind of motor bearing end cover is provided.
The utility model is to be achieved through the following technical solutions:
[0005]a kind of 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, and described oil supply tank is provided with oil supplying hole, and described oil supplying hole upper end is provided with screw.
[0006]as optimal technical scheme of the present utility model, the inner side of described lid is provided with U-lag.
[0007]as optimal technical scheme of the present utility model, the shape of described oil supply tank is half elliptic, 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.
[0008]as optimal technical scheme of the present utility model, described oil supply tank has several, and the distance of adjacent oil supply tank is that 1.5mm is between 3mm.
[0009]as optimal technical scheme of the present utility model, the radius of described oil supplying hole is that 2mm is between 4mm.
When on-the-spot use, first, operating personnel install the utility model 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 beneficial effects of the utility model are: the utility model 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 being set, screw contributes 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.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 1 is structural representation of the present utility model.
[0015]described a kind of motor bearing end cover, comprise lid 1, described lid 1 is provided with the axis hole 2 of fixed electrical machinery rotating shaft, described axis hole 2 is provided with oil supply tank 3, the shape of described oil supply tank 3 is half elliptic, the major axis of oil supply tank 3 is 1.6mm, the minor axis of oil supply tank 3 is 1mm, oil supply tank 3 has several, and the distance of adjacent oil supply tank 3 is 2mm, oil supply tank 3 is provided with oil supplying hole 4, contribute to timely countershaft to carry out fuel feeding with the oil supply tank 3 of oil supplying hole 4, contribute to reduce friction, the radius of described oil supplying hole 4 is 2mm, oil supplying hole 4 upper ends are provided with screw 5, screw 5 contributes to store more lubricating oil, contribute to extend lubrication time, improve the life-span of rotating shaft, the inner side of described lid 1 is provided with U-lag 6.
When on-the-spot use, first, operating personnel install the utility model in place, rotating shaft is arranged in axis hole 2, then screw 5 is screwed out, and lubricating oil is added in oil supplying hole 4, and lubricating oil enters in oil supply tank 3 through oil supplying hole 4, can countershaft fuel feeding.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any amendments of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection range of the present utility model.
