Abstract
The utility model discloses a kind of casing structures of motor in electric automobile, including shell, and bearing installation cavity is equipped on shell, oil storage tank is equipped on the bottom surface of bearing installation cavity, oil road is equipped on the side wall of shell, which connects with oil storage tank, and beam hanger is equipped with out in the oil road.The utility model is not necessarily to dismantle the discharge for the lubricant that bearing (ball) cover can be achieved with siltation with bearing, and using effect is good.
Description
Technical field：
The utility model is related to a kind of casing structures of motor in electric automobile.
Background technology：
Existing motor in electric automobile when in use, imitate by the rotation to prevent mechanical bearing from wearing and increase mechanical bearing
Rate often increases lubricant on mechanical bearing, but often addition lubricant can cause siltation of the lubricant on bearing, therefore
After using the section time, it is often required to carry out dredging processing, existing dredging processing is generally will be under bearing cap and bearing removal
Come, this kind of mode is on the one hand cumbersome, on the other hand assembling bearing repeatedly, can also cause to damage to bearing.
Utility model content：
The utility model is to provide a kind of machine of motor in electric automobile to solve the above-mentioned problems of the prior art
Shell structure.
Technical solution used by the utility model has：A kind of casing structure of motor in electric automobile, including shell, in shell
Body is equipped with bearing installation cavity, and oil storage tank is equipped on the bottom surface of bearing installation cavity, and oil road is equipped on the side wall of shell, should
Oil road connects with oil storage tank, and beam hanger is equipped with out in the oil road.
Further, it is described go out beam hanger include fixed part and spiral bar portion, the fixed part is fixedly connected with spiral bar portion,
External screw thread is equipped on the outer circle wall of fixed part, spiral bar portion passes through oil road and stretches in oil storage tank, and fixed part screw thread connects
It is connected on the inner wall of oil road.
Further, the oil road is step-like, and the axis of oil road is perpendicular to the axis of shell.
Further, it is arranged with sealing ring in the spiral bar portion, be tightened portion, and sealing ring is closely against by fixed part
On the step surface of oil duct.
The utility model has the advantages that：The utility model can be achieved with becoming silted up without dismantling bearing (ball) cover with bearing
The discharge of long-pending lubricant, using effect are good.
Description of the drawings：
Fig. 1 is the utility model structure chart.
Fig. 2 is the structure chart for going out beam hanger in the utility model.
Fig. 3 is the application structure figure of the utility model.
Specific implementation mode：
The utility model will be further described below with reference to the accompanying drawings.
As shown in Figure 1 to Figure 3, the utility model discloses a kind of casing structure of motor in electric automobile, including shell 1,
Shell 1 is equipped with bearing installation cavity 11, and oil storage tank 12 is equipped on the bottom surface of bearing installation cavity 11, is set on the side wall of shell 1
There is oil road 13, which connects with oil storage tank 12, and beam hanger 3 is equipped with out in oil road 13.
The beam hanger 3 that goes out in the utility model includes fixed part 31 and spiral bar portion 32, and fixed part 31 is solid with spiral bar portion 32
Fixed connection, is equipped with external screw thread on the outer circle wall of fixed part 31, and spiral bar portion 32 passes through oil road 13 and stretches in oil storage tank 12
Interior, fixed part 31 is threaded on the inner wall of oil road 13.
Oil road 13 is step-like, and the axis of oil road 13 is perpendicular to the axis of shell 1.
To ensure leakproofness, it is arranged with sealing ring in spiral bar portion 32, be tightened portion 31, and fixed part 31 is by sealing ring
It is closely against on the step surface of oil road 13.
In use, when siltation needs to exclude lubricant, the fixed part 31 of beam hanger 3 is unscrewed out, beam hanger 3 is then rotated out,
The lubricant of siltation is discharged the spiral bar portion 32 gone out on beam hanger 3.The utility model is without dismantling bearing (ball) cover and bearing energy
Realize that the discharge of the lubricant of siltation, using effect are good.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
It for art personnel, can also make several improvements without departing from the principle of this utility model, these improvement also should be regarded as
The scope of protection of the utility model.
