Abstract
Description
Technical Field
[0001] This utility model belongs to the field of motor technology, specifically relating to a motor vibration damping mounting structure. 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, motors are usually connected to timing belts and transmission chains to drive the equipment. When the equipment gets stuck or stops suddenly, the motor rotor is pulled by the timing belt or transmission chain. Since the motor is usually tightly connected to the mounting platform, the pulling force is 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 motor vibration damping installation structure.
[0005] The above-mentioned technical problems of this utility model are mainly solved by the following technical solution: a motor vibration damping mounting structure, including a housing, a stator core and a rotor core, wherein the stator core is disposed inside the housing and the rotor core is disposed inside the stator core, the housing includes a front cover and a rear cover, and each of the front cover and the rear cover includes a bearing seat and a rubber ring, wherein the rubber ring covers the bearing seat.
[0006] Preferably, the front cover and the rear cover clamp the stator core inside the housing. The edges of the front cover and the rear cover are provided with snap-fit steps. The snap-fit steps include two contact surfaces, and each of the two contact surfaces is provided with a glue storage groove.
[0007] Preferably, the stator core includes multiple coils arranged in a circular array, and a plastic sealing layer is provided between the coils, the plastic sealing layer covering all the coils.
[0008] Preferably, the outer ring surface of the stator core and the inner ring surface of the housing are provided with two mounting grooves, and each of the two mounting grooves is provided with a support ring, and the two support rings support the stator core in the housing.
[0009] Preferably, the stator core is provided with two movable graphite rings at both ends. The two movable graphite rings, one large and one small, are arranged on the front and rear end faces of the stator core. The front end cover and the rear end cover are each provided with a fixed graphite ring that cooperates with the movable graphite ring. The movable graphite rings at both ends of the stator core are in contact with the fixed graphite rings on the front end cover and the rear end cover.
[0010] Preferably, the support ring includes a plurality of interconnected concave portions and convex portions, wherein the concave portions abut against the mounting groove of the stator core and the convex portions abut against the mounting groove of the housing.
[0011] The beneficial effects of this utility model are as follows: by setting rubber rings on the front and rear covers used to support the rotor core, the bearing seats are supported by the rubber rings. When the drive equipment to be driven is jammed or stops suddenly, the rubber rings will buffer and reduce the impact force on the rotor core when the synchronous belt or transmission chain pulls the rotor core, thereby avoiding deformation of the rotor core, avoiding damage to the motor, and increasing the service life of the motor.
[0012] A support ring is installed between the stator core and the housing. When the rotor core is deformed significantly, the support ring acts as a buffer to prevent the rotor core, stator core and housing from jamming and rendering the motor unusable. Attached Figure Description

[0017] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.
[0018] Example: A motor vibration damping mounting structure, such as Figures 1-3 As shown, it includes a housing 1, a stator core 2 and a rotor core 3. The stator core 2 is located inside the housing 1, and the rotor core 3 is located inside the stator core 2. The housing 1 includes a front cover 4 and a rear cover 5. Both the front cover 4 and the rear cover 5 include a bearing seat 6 and a rubber ring 7. The rubber ring 7 covers the bearing seat 6.
[0019] The front cover 4 and the rear cover 5 clamp the stator core 2 inside the housing 1. The edges of the front cover 4 and the rear cover 5 are provided with snap-fit steps. The snap-fit steps include two contact surfaces 8. Each of the two contact surfaces 8 is provided with a glue storage groove 9, which facilitates the storage of sealant for sealing.
[0020] The stator core 2 includes multiple coils 10, which are evenly distributed in a circular array, and a plastic sealing layer 11 is provided between the coils 10, which covers all the coils 10.
[0021] The outer ring surface of the stator core 2 is provided with two mounting grooves 12 on both the plastic sealing layer 11 and the inner ring surface of the housing 1. Each of the two mounting grooves 12 is provided with a support ring 13, and the two support rings 13 support the stator core 2 inside the housing 1.
[0022] The stator core 2 has two movable graphite rings 14 at both ends. The two movable graphite rings 14 are arranged on the front and rear end faces of the stator core 2, one large and one small. The front cover 4 and the rear cover 5 are each provided with two movable graphite rings 14 and fixed graphite rings 15 that cooperate with them. The movable graphite rings 14 at both ends of the stator core 2 are in contact with the fixed graphite rings 15 on the front cover 4 and the rear cover 5.
[0023] The support ring 13 includes a plurality of interconnected concave portions 16 and convex portions 17. The concave portions 16 abut against the mounting groove 12 of the stator core 2, and the convex portions 17 abut against the mounting groove 12 of the housing 1.
[0024] The principle of this utility model is as follows: When the motor is in use, if the drive equipment to be driven gets stuck or stops suddenly, the synchronous belt or transmission chain pulls the rotor core 3. Under the action of the pulling force, the rotor core 3 will be displaced, the corresponding bearing seat 6 will move, and the rubber ring 7 will buffer, thereby reducing the impact force on the rotor core 3, thus avoiding deformation of the rotor core 3, avoiding damage to the motor, and increasing the service life of the motor.
[0025] A support ring 13 is provided between the stator core 2 and the housing 1. When the rotor core 3 is deformed by a large amount, the support ring 13 plays a buffering role again when it drives the rotor core 3 to twist, so as to prevent the rotor core 3, stator core 2 and housing 1 from getting stuck and making the motor unusable.
[0026] 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.
