Description

Technical Field

[0001] The utility model relates to the technical field of motor bearing end covers, in particular to a motor bearing end cover. Background Art

[0002] The motor bearing end cover is mainly used to install the bearing, thus ensuring the normal operation of the shaft. The motor end cover is a cover installed at both ends of the motor casing, commonly known as the end cover. The main function of the end cover is to place the rotor bearing.

[0003] When the motor starts, it will vibrate and generate a lot of heat. The existing motor bearing end cover has a relatively single function. When in use, it can only achieve the installation of the bearing, and it is difficult to assist in the heat dissipation of the motor after starting, so it has low practicality. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a motor bearing end cover.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A motor bearing end cover comprises an end cover body, four evenly distributed mounting seats are fixedly mounted on the outer side wall of the end cover body, four evenly distributed fixing blocks are fixedly mounted on the outer side wall of the end cover body, cavities are respectively formed in the four fixing blocks, and auxiliary mechanisms are respectively arranged on the four fixing blocks.

[0007] Preferably, the auxiliary mechanism includes a sliding block arranged in the cavity and slidably connected to the inner wall of the cavity, two telescopic rods are fixedly installed on the inner bottom of the cavity, the telescopic ends of the two telescopic rods are fixedly connected to the bottom of the sliding block, two tension springs are fixedly connected between the sliding block and the inner bottom of the cavity, a top hole connected to the cavity is opened on the top of the fixed block, an air inlet and an air outlet pipe connected to the cavity are arranged on the side wall of the fixed block, and a counterweight block is fixedly installed on the bottom of the sliding block.

[0008] Preferably, the four mounting seats and the four fixing blocks are distributed at intervals.

[0009] Preferably, two mounting holes are provided on each of the four mounting seats.

[0010] Preferably, a filter screen is provided in the air inlet, and a one-way valve is provided in both the air inlet and the air outlet pipe.

[0011] Preferably, the air inlet hole and the end of the air outlet pipe communicating with the cavity are both located below the sliding block.

[0012] Beneficial effects of the utility model:

[0013] By setting up an auxiliary mechanism, after the end cover body is installed and the motor is started, the sliding block can slide up and down in the cavity through the inertia of the counterweight block, so that air can enter and exhaust. The exhausted air is blown toward the motor, which can speed up air circulation, improve heat dissipation effect, and facilitate use. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Reference Figure 1-Figure 3 A motor bearing end cover comprises an end cover body 1, four evenly distributed mounting seats 2 are fixedly mounted on the outer side wall of the end cover body 1, four evenly distributed fixing blocks 3 are fixedly mounted on the outer side wall of the end cover body 1, the four mounting seats 2 and the four fixing blocks 3 are arranged in an interval manner, two mounting holes 8 are provided on the four mounting seats 2, cavities 12 are provided in the four fixing blocks 3, and auxiliary mechanisms are provided on the four fixing blocks 3;

[0020] The auxiliary mechanism includes a sliding block 9 which is arranged in the cavity 12 and is slidably connected to the inner wall of the cavity 12, two telescopic rods 10 are fixedly installed on the inner bottom of the cavity 12, and the telescopic ends of the two telescopic rods 10 are fixedly connected to the bottom of the sliding block 9, and two tension springs 11 are fixedly connected between the sliding block 9 and the inner bottom of the cavity 12, a top hole 5 connected to the cavity 12 is opened on the top of the fixed block 3, an air inlet 6 and an air outlet pipe 4 connected to the cavity 12 are arranged on the side wall of the fixed block 3, a counterweight block 13 is fixedly installed on the bottom of the sliding block 9, a filter screen 7 is arranged in the air inlet 6, and a one-way valve is arranged in the air inlet 6 and the air outlet pipe 4, and the ends of the air inlet 6 and the air outlet pipe 4 connected to the cavity 12 are both located below the sliding block 9.

[0021] When the utility model is used, by setting the mounting seat 2 and the mounting hole 8, the screw can be screwed into the mounting hole 8 to achieve the installation of the end cover body 1. When the motor is in normal use, a certain vibration will occur, thereby driving the end cover body 1 to vibrate. When the end cover body 1 vibrates, the mass of the counterweight block 13 is large, and the inertia is also large. By setting the telescopic rod 10 and the tension spring 11, the counterweight block 13 and the sliding block 9 can slide up and down. Since a one-way valve is provided in the air inlet 6 and the air outlet pipe 4, the air inlet 6 can only enter but not exit, and the air outlet pipe 4 can only exit but not enter. Therefore, when the sliding block 9 slides upward, the external air enters the cavity 12 through the air inlet 6 after being filtered by the filter screen 7. When the sliding block 9 slides downward, the air in the air inlet cavity 12 is discharged to the outside of the cavity 12 through the air outlet pipe 4 and finally blows toward the motor, thereby performing a certain heat dissipation on the motor.

[0022] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
