Description

Technical Field

[0001] The utility model belongs to the technical field of motors, and in particular relates to a noise-reducing end cover motor. Background Art

[0002] An end cover motor is a DC motor whose end cover is usually used to fix the internal components of the motor and protect the internal structure of the motor. The end cover motor is usually used in industrial machinery, automobiles, ships and other fields. When the motor is connected, the motor and the gear box are connected separately, resulting in the connection being exposed to the outside. In addition, the overall swing is relatively large during operation, resulting in relatively loud noise, which affects the use of the staff. Therefore, a noise-reducing end cover motor is proposed.

[0003] For example, a Chinese patent with publication number CN219875328U discloses a brushless motor end cover with a noise reduction function, including a shell, a noise reduction mechanism is arranged inside the shell, and the noise reduction mechanism is provided with a fixed cylinder, one end of the fixed cylinder is fixedly installed with the shell, a secondary cylinder is fixedly installed on the outer side of the fixed cylinder, one end of the secondary cylinder is slidably connected with the shell, a tertiary cylinder is installed on the outer side of the secondary cylinder through a transition fit, and the outer side of the tertiary cylinder is slidably connected with the inner wall of the shell.

[0004] The existing technical documents have the following problems:

[0005] The existing technical documents have some shortcomings when used, such as: when the motor is connected, the motor and the gear box are connected separately, resulting in the connection being exposed to the outside, and the overall swing is relatively large during operation, resulting in relatively large noise, affecting the use of the staff, and at the motor lead outlet, the wire is easy to contact the bearing surface, which is easy to cause friction, resulting in serious wear of the wire, thereby reducing the service life of the wire. In view of this, we propose a noise-reducing end cover motor. Utility Model Content

[0006] The purpose of the utility model is to provide a noise-reducing end cover motor in view of the above-mentioned technical problems, so as to achieve the effect of reducing the noise caused by the operation of the motor and increasing the service life of the lead wire.

[0008] Based on the above structure, through the coordinated use of the housing, the front cover terminal and the gear box, the motor and the gear box are installed in an integrated manner, and the assembly is convenient, thereby improving the overall stability of the motor and reducing the noise during operation. Through the coordinated use of the rear cover, the flat support head, the flat support plate and the lead-out groove, the lead-out wires must first pass through the wire holes of the flat support plate and the wire holes of the flat support head, and finally lead out from the motor lead-out groove.

[0009] Preferably, a fixing bolt is fixedly installed on the other side of the gear box, and the fixing bolt is made of stainless steel. The fixing bolt is used to facilitate the connection between the gear box and the machine body.

[0010] Preferably, a bearing is sleeved on the surface of the rear cover, and the bearing is made of steel, so that the rear cover can be conveniently connected to an external device by using the bearing.

[0011] Preferably, a motor terminal is installed through the other side of the body, so that the housing can be used to facilitate the operation of the motor.

[0012] Preferably, a soft rubber pad is fixedly installed on the other side of the motor terminal, and the soft rubber pad is made of rubber material to reduce the vibration of the machine body.

[0013] Preferably, pressure relief pads are fixedly mounted on both ends of the inner shell, and a connecting seat is fixedly mounted on one side of the inner shell, and the connecting seat is used to connect with the gear box.

[0014] Preferably, a connecting groove is fixedly provided on one side of the connecting seat, and the connecting seat is made of PVC material, and the connecting groove is used to facilitate connection with the fixing bolt.

[0015] The beneficial effects of the utility model are:

[0017] 2. The noise-reducing end cover motor is connected to the outer shell through the back cover, and then the back cover is conveniently installed through the buckle groove. Then the gap for connection with the external device is increased through the flat support plate, and then the lead wire is conveniently inserted through the lead wire outlet groove. Through the coordinated use of the back cover, the flat support head, the flat support plate and the lead wire outlet groove, the lead wire must first pass through the wire hole of the flat support plate and the wire hole of the flat support head, and finally lead the wire from the motor to the lead wire outlet groove, mainly to prevent the wire from contacting the shaft surface, thereby preventing friction, avoiding wire breakage caused by wear, and thus increasing the service life of the lead wire.
