Description

Technical Field

[0001] The utility model relates to the technical field of motor end covers, in particular to a replaceable motor end cover functional component. Background Art

[0002] An electric motor (commonly known as a "motor") is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. It is categorized into motors (symbolized by M) and generators (symbolized by G). Based on their structure and operating principle, they can be divided into DC motors, asynchronous motors, and synchronous motors. Asynchronous motors can be further divided into induction motors and AC commutator motors. Induction motors can be further divided into three-phase asynchronous motors, single-phase asynchronous motors, and shaded-pole asynchronous motors.

[0003] In the field of motor manufacturing and maintenance, backstops and bearing covers are key components, primarily used to prevent reverse rotation of the motor and ensure stable operation of the bearings. Traditional motor end covers typically require disassembly of the entire cover when the backstop or bearing needs to be replaced, which is both time-consuming and labor-intensive, making it difficult to achieve universal use of backstops and bearing covers. Furthermore, traditional structural designs are complex, the end covers themselves have low strength, and a short service life, increasing manufacturing and maintenance costs. To improve motor maintenance efficiency and reduce replacement time and costs, it is particularly important to develop a simple, replaceable motor end cover functional component.

[0028] Reference Figures 1 to 4 , is an embodiment of the present utility model, which provides a replaceable motor end cover functional assembly, including a built-in unit 100 and a cover unit 200;

[0029] The built-in unit 100 includes a backstop shaft core 101, a backstop shaft sleeve 102, a gasket 103, a bearing 104 and a shaft body 105; the backstop shaft sleeve 102 is sleeved on the backstop shaft core 101, and a gasket 103 is arranged on the rear side of the backstop shaft core 101 to play a buffering and fixing role; the bearing 104 is arranged on the shaft body 105 on the rear side of the backstop shaft core 101, and the bearing 104 is also arranged in the inner hole 2031 of the flange end cover 203. The backstop inner cover 202 is arranged on the rear side of the bearing 104; a flat key 1051 is arranged on the shaft body 105, and the shaft body 105 is used in conjunction with the backstop sleeve 102 through the flat key 1051. The flat key 1051 is embedded between the shaft body 101 and the backstop sleeve 102. The function of the flat key 1051 is to prevent the backstop sleeve 102 from rotating on the shaft body 105 to ensure a reliable connection between the two, thereby ensuring the effective function and stable installation of the backstop.

[0030] The cover unit 200 includes a check valve end cover 201, a check valve inner cover 202 and a flange end cover 203. The bearing 104 is installed inside the flange end cover 203. The check valve end cover 201 and the check valve inner cover 202 are respectively fixed on the front and rear sides of the flange end cover 203. After the check valve shaft core 101, the check valve shaft sleeve 102, the gasket 103 and the shaft body 105 are combined, they are fixed on the flange end cover 203. An inner hole 2031 is provided on the flange end cover 203, the shaft body 105 is built in the inner hole 2031, and the check valve shaft core 101 is sleeved on the shaft body 105. Extended convex rings 2032 are arranged on both the inner and outer sides of the inner hole 2031. Reinforcing ribs 2033 and heat dissipation ribs 2035 are arranged in a circular array on the extended convex rings 2032. The cross-section of the reinforcing rib 2033 is a trapezoidal structure with a narrow upper part and a wide lower part. The longitudinal section of the reinforcing rib 2033 is a "U" - shaped structure with both sides expanding outwards obliquely. The two ends of the reinforcing rib 2033 are respectively connected to the extended convex ring 2032 and the outer opening of the end cover, ensuring a large contact area between the reinforcing rib 2033 and the flange end cover 203. At the same time, the overall rigidity and stability of the product are improved through the reinforcing rib 2033 with relatively high strength, preventing the vibration during the operation of the motor. The heat dissipation rib 2035 can preferably be made of aluminum material and has heat dissipation performance.

[0031] Reinforcing ribs 2034 are arranged in a circular array on the circumferential outer side wall of the flange end cover 203. The cross-section of the reinforcing rib 2034 is a triangular structure, which can play a role in stably supporting the outer ring cavity wall and the end cover stop of the flange end cover 203 itself, and can further increase the overall structural strength of the cover unit 200. Installation hole positions for cooperating with the flange end cover 203 are provided on both the check valve inner cover 202 and the check valve end cover 201. The installation hole positions are used to install fasteners. After the fasteners pass through the installation hole positions, they are connected to the flange end cover 203, ensuring the reliability of the installation.

[0032] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
