A multi-directional vibration damping device for motors

Abstract

A multi-directional vibration damping device for motors belongs to the field of motor technology. By setting a support ring between the motor body and the motor housing, the support ring supports the motor body. When the driven equipment jams or stops suddenly, the support ring buffers the impact force on the motor body when the synchronous belt or transmission chain pulls on the motor body. Displacement and force relief occur within the motor housing through the support ring, thus preventing deformation of the rotor core and avoiding damage to the motor, further increasing the motor's service life. The support ring is equipped with a U-shaped swing ring, allowing the motor body to swing circumferentially along its axis within the motor housing. When the platform or bracket on which the motor is installed vibrates, it effectively transmits the vibration of the motor housing to the motor body, preventing it from affecting the operation of the motor body.

Description

Technical Field

[0001] This utility model belongs to the field of motor technology, specifically relating to a multi-directional vibration damping device for motors. Background Technology

[0002] Electric motors are the power drive devices for many mechanical devices. The power of an electric motor is generally transmitted through a drive wheel mounted on a central shaft to drive other mechanical devices.

[0003] In the prior art, the motor rotor is usually rigidly connected to the housing. When the motor is in use, it is usually connected to the synchronous belt and transmission chain to drive the required equipment. When the driven equipment jams or stops suddenly, the motor rotor will be pulled by the synchronous belt or transmission chain. Since the motor is usually tightly connected to the mounting platform, the pulling force will be directly applied to the motor rotor, causing the motor shaft to be impacted and thus damaging the motor. Summary of the Invention

[0004] The present invention aims to solve the technical problems existing in the prior art and provide a multi-directional vibration damping device for motors.

[0005] The above-mentioned technical problems of this utility model are mainly solved by the following technical solution: a multi-directional vibration damping device for a motor, including a motor cover, a motor body and a support ring, wherein the motor body is disposed inside the motor cover, and the support ring is supported between the motor body and the motor cover; the front end of the motor body is provided with a first connecting ring for connection, and the front end of the motor cover is provided with a second connecting ring for connection, wherein the support ring is engaged between the first connecting ring and the second connecting ring, wherein the plane of the first connecting ring is perpendicular to the axis of the motor body, and the plane of the second connecting ring is parallel to the axis of the motor cover.

[0006] Preferably, the support ring includes a first retaining ring and a second retaining ring, the first retaining ring and the second retaining ring being U-shaped, and a U-shaped swing ring connecting the first retaining ring and the second retaining ring. The first retaining ring is engaged with the first connecting ring, and the second retaining ring is engaged with the second connecting ring.

[0007] Preferably, both the first and second retaining rings have a reinforcing ring inside, which is made of stainless steel and is U-shaped.

[0008] Preferably, the U-shaped swing ring includes two connecting arms, and the included angle between the two connecting arms is 5° to 10°.

[0009] Preferably, the U-shaped swing ring has an inward-facing opening and is positioned between a first connecting ring and a second connecting ring.

[0010] The beneficial effects of this utility model are as follows: By setting a support ring between the motor body and the motor cover, the motor body is supported by the support ring. When the drive equipment to be driven jams or stops suddenly, the synchronous belt or transmission chain pulls the motor body, and the support ring buffer reduces the impact force on the motor body. The displacement of the support ring inside the motor cover relieves the force, thereby avoiding deformation of the rotor core, avoiding damage to the motor, and further increasing the service life of the motor.

[0011] The support ring is equipped with a U-shaped swing ring, which allows the motor body to swing circumferentially along the axis inside the motor cover. When the platform or bracket on which the motor is installed vibrates, it can effectively transmit the vibration of the motor cover to the motor body, thus avoiding affecting the operation of the motor body.

[0015] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0016] Example: A multi-directional vibration damping device for a motor, such as Figures 1-2 As shown, the device includes a motor cover 1, a motor body 2, and a support ring 3. The motor body 2 is located inside the motor cover 1, and the support ring 3 is supported between the motor body 2 and the motor cover 1. The front end of the motor body 2 is provided with a first connecting ring 4 for connection, and the front end of the motor cover 1 is provided with a second connecting ring 5 for connection. The support ring 3 is engaged between the first connecting ring 4 and the second connecting ring 5. The plane of the first connecting ring 4 is perpendicular to the axis of the motor body 2, and the plane of the second connecting ring 5 is parallel to the axis of the motor cover 1.

[0017] The support ring 3 includes a first retaining ring 6 and a second retaining ring 7. The first retaining ring 6 and the second retaining ring 7 are U-shaped. A U-shaped swing ring 8 is provided between the first retaining ring 6 and the second retaining ring 7 for connection. The first retaining ring 6 is engaged with the first connecting ring 4, and the second retaining ring 7 is engaged with the second connecting ring 5.

[0018] Both the first retaining ring 6 and the second retaining ring 7 have a reinforcing ring 9 inside. The reinforcing ring 9 is made of stainless steel and is U-shaped.

[0019] The U-shaped swing ring 8 includes two connecting arms 10, and the included angle between the two connecting arms 10 is 5° to 10°.

[0020] The U-shaped swing ring 8 has its opening facing inward and is located between the first connecting ring 4 and the second connecting ring 5.

[0021] The principle of this utility model is as follows: When the drive equipment to be driven is jammed or stops suddenly, the synchronous belt or transmission chain pulls the motor body 2. Under the action of the pulling force, the motor body 2 will be displaced. At this time, the U-shaped swing ring 8 in the support ring 3 will be twisted, which will drive the motor body 2 to buffer, thereby reducing the impact force on the motor body 2, thus avoiding damage to the motor and increasing the service life of the motor.

[0022] The two connecting arms 10 in the U-shaped swing ring 8 have an angle of 5° to 10°, which can move the two swing arms away from the motor cover 1 and the motor body 2, thereby increasing the range of motion between them. When subjected to impact force, there is a larger range of motion. The reinforcing ring 9 is set in the first retaining ring 6 and the second retaining ring 7, which can increase the clamping force of the first retaining ring 6 and the second retaining ring 7 on the first connecting seat and the second connecting seat, increase the connection strength, and prevent them from falling off during use.

[0023] Finally, it should be noted that the above embodiments are merely representative examples of this utility model. Obviously, this utility model is not limited to the above embodiments and can have many variations. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model should be considered to fall within the protection scope of this utility model.
