Abstract

This utility model relates to the field of motor end cover technology and discloses a motor end cover that combines dustproof and heat dissipation performance. It includes: multiple modular cover bodies installed at the end of the motor housing; each modular cover body has a ventilation structure with louvers installed on it; each modular cover body includes an end panel, a first arc-shaped plate, and a second arc-shaped plate. This motor end cover, which combines dustproof and heat dissipation performance, integrates a louvered ventilation structure on the modular cover modules, allowing for the exchange of air between the motor's interior and exterior.

Description

Technical Field

[0001] This utility model relates to the field of motor end cover technology, specifically a motor end cover that combines dustproof and heat dissipation performance. Background Technology

[0002] In the application of medium and large-sized and industrial motors, in order to balance cost-effectiveness and ease of maintenance, the existing technology generally adopts the solution of installing a cooling fan on the motor shaft to achieve heat dissipation by utilizing the airflow around the motor.

[0003] However, this method has significant limitations: after the motor is running, the ambient temperature rises, which leads to a decrease in heat dissipation efficiency, especially under high-temperature conditions, where the heat dissipation effect is even worse. Currently, large motors are widely used in oil fields, textile and chemical fiber industries, ceramic and glass industries, as well as in fan and water pumps that require long-term operation. However, these places are often harsh environments with dust, which can easily cause air duct blockage due to dust accumulation, further weakening the heat dissipation performance. Dust and biological intrusion can easily damage the motor end cover and the cooling fan, thereby shortening the overall service life of the motor. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a motor end cover that combines dustproof and heat dissipation performance, thus solving the problems mentioned in the background.

[0005] This utility model provides the following technical solution: a motor end cover that combines dustproof and heat dissipation performance, comprising: multiple modular cover bodies installed at the end of the motor housing, each of the modular cover bodies being provided with a ventilation structure, and louvers being installed on the surface of the modular cover body at the position corresponding to the ventilation structure;

[0006] Each of the modular covers includes an end panel, a first arc-shaped plate, and a second arc-shaped plate, wherein the end panel is connected to one side of the first arc-shaped plate, and the second arc-shaped plate is connected to the other side of the first arc-shaped plate.

[0007] Preferably, the ventilation structure is a rectangular hole on the end panel, the position of the louver corresponds to the position of the rectangular hole, and the louver is provided with screws, and the louver is installed on the surface of the end panel by screws.

[0008] Preferably, a first strip and a second strip are provided on the opposite surfaces of adjacent modular covers, the first strip being connected to the surface of the end panel, and the second strip being connected to the surface of the first arc-shaped plate.

[0009] Preferably, both the first and second strips have mounting holes.

[0010] Preferably, the number of modular caps is three, and the three modular caps are assembled to form a circular end cap.

[0011] Preferably, there are two circular end caps, one of which is installed at one end of the motor housing and the other is installed at the other end of the motor housing. The two circular end caps and the motor housing together form a circulating air duct.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This motor end cover, which combines dustproof and heat dissipation performance, features a modular cover design with an integrated louvered ventilation structure. This allows for the exchange of air between the motor's interior and exterior. While ensuring adequate ventilation area, this structure effectively guides airflow and forms a complete circulating air duct, greatly improving the motor's heat dissipation efficiency. The inclined blade design of the louvers prevents most dust, impurities, and water droplets from directly entering the motor, reducing the direct impact of dust on the internal cooling fan. This, in turn, enhances heat dissipation capacity and extends the motor's service life.

[0014] 2. This motor end cover, which combines dustproof and heat dissipation performance, is assembled from multiple modular cover bodies. The modular assembly structure divides the end cover into multiple parts, which can distribute and balance the stress, avoiding the deformation or cracking problems caused by local stress concentration in traditional integral end covers. This significantly enhances the overall structural strength, mechanical stability and impact resistance of the end cover. Attached Figure Description

There are two circular end caps, one of which is installed at one end of the motor housing and the other at the other end. The two circular end caps and the motor housing together form a circulating air duct. The three modular cover bodies 1 are assembled to form a circular end cap.
