Abstract
Description
Technical Field
[0001] This utility model belongs to the field of motor noise reduction technology, specifically relating to a noise reduction device for a motor gearbox. Background Technology
[0002] Currently, there is a great deal of research on automotive motor systems both domestically and internationally, mainly focusing on the application of new electric motors and the improvement of motor system control strategies. Several key issues to consider include cost, efficiency, reliability, weight, size, noise, and durability.
[0003] Existing technologies typically improve efficiency and reliability, but this often results in higher costs and heavier components. However, focusing on cost and weight often leads to unsatisfactory efficiency and noise levels. Currently, there is no good solution that can balance these key issues of cost, efficiency, and weight. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a noise reduction device for motor gearboxes, which has the advantage of easy noise reduction.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a noise reduction device for a motor gearbox, comprising a housing, a gasket fixedly connected to one outer wall of the output end of the housing, a positioning ring fixedly connected to the inner wall of the gasket, the gasket being made of soft rubber, and the positioning ring being located on both sides of the gasket.
[0006] Through the above technical solution, the material of the gasket between the motor housing and the positioning ring is changed to soft rubber. Soft rubber has the function of absorbing vibration and reducing noise, ensuring that the motor vibration and noise are reduced when the motor is rotating at high speed.
[0007] Preferably, the inner wall of the positioning ring is provided with a main shaft, one side of which is located inside the outer casing and the other side of which is located outside the outer casing.
[0008] The above technical solution can achieve the output effect. One side of the main shaft is located inside the housing, and the other side of the main shaft is located outside the housing, which allows the rotor inside the housing to drive the main shaft to rotate, thereby achieving the output effect.
[0009] Compared with the prior art, the beneficial effects of this utility model are:
[0010] 1. The material of the gasket between the motor housing and the positioning ring has been changed to soft rubber. Soft rubber has the function of absorbing vibration and reducing noise, ensuring that the motor vibration and noise are reduced when the motor is rotating at high speed. Since the positioning ring and gasket are small in size, space is saved and costs are reduced. At the same time, it can quickly solve the vibration and noise of the motor gear reducer.
[0011] 2. One side of the main shaft is located inside the housing, and the other side of the main shaft is located outside the housing, which allows the rotor inside the housing to drive the main shaft to rotate, thereby achieving the output effect. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] Example 1:
[0017] Please see Figures 1-2 This utility model provides a technical solution: a noise reduction device for a motor gearbox, including a housing 1, a gasket 2 fixedly connected to one outer wall of the output end of the housing 1, a positioning ring 3 fixedly connected to the inner wall of the gasket 2, the gasket 2 being made of soft rubber, and the positioning ring 3 being located on both sides of the gasket 2.
[0018] In this embodiment, the material of the gasket 2 between the motor housing 1 and the positioning ring 3 is changed to soft rubber. Soft rubber has the function of absorbing vibration and reducing noise, ensuring that the motor vibration and noise are reduced when the motor is rotating at high speed.
[0019] Example 2:
[0020] Please see Figures 1-2 Based on Embodiment 1, this utility model provides a technical solution: the inner wall of the positioning ring 3 is provided with a main shaft 4, one side of the main shaft 4 is located inside the outer shell 1, and the other side of the main shaft 4 is located outside the outer shell 1.
[0021] In this embodiment, it can achieve the effect of output. One side of the main shaft 4 is located inside the housing 1, and the other side of the main shaft 4 is located outside the housing 1, so that the rotor inside the housing 1 can drive the main shaft 4 to rotate, thereby achieving the effect of output.
[0022] The working principle and usage process of this utility model: The material of the gasket 2 between the motor housing 1 and the positioning ring 3 is changed to soft rubber. Soft rubber has the function of absorbing vibration and reducing noise, ensuring that the motor vibration and noise are reduced when the motor is rotating at high speed, which can achieve the output effect. One side of the main shaft 4 is located inside the housing 1, and the other side of the main shaft 4 is located outside the housing 1, which allows the rotor inside the housing 1 to drive the main shaft 4 to rotate, thereby achieving the output effect.
[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
