Combined motor end cover

Abstract

The utility model discloses a combined motor end cover, which comprises a motor end cover and an exchange assembly, and the exchange assembly comprises a clamping groove arranged in the motor end cover in a penetrating manner and an installation lug movably matched and installed in the clamping groove. According to the combined motor end cover provided by the utility model, a combined structure is adopted between the mounting lug clamped and mounted in the clamping groove in the motor end cover and the motor end cover body, so that after the mounting lug is damaged in use, the mounting lug can be conveniently replaced by dismounting a compression ring at the inner end of the motor end cover; therefore, the problem that the whole motor end cover is scrapped after a small part mounting lug on the motor end cover is damaged or deformed is avoided, and meanwhile, the sealing rings mounted in the inner notch and the outer notch between the upper part of the pressing ring and the motor end cover can ensure the sealing performance of the combined motor end cover after being mounted, so that the service life of the combined motor end cover is prolonged. Therefore, the influence of the combined structure of the mounting lugs on the sealing performance of the motor end cover is avoided.

Description

Technical Field

[0001] The utility model relates to the technical field of motors, in particular to a combined motor end cover. Background Art

[0002] A motor is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. The motor end cover is a component on the upper end of the motor, mainly installed at the front end of the motor to ensure the sealing of the front end of the motor and the stable operation of the shaft.

[0003] Existing motor end covers, such as the one disclosed in publication number CN216086316U, have the advantages of greater strength, reliable lubrication of bearings and better heat dissipation performance of the end cover. However, the outer mounting ears of this motor end cover and the motor end cover body adopt an integrated structure, and then when the mounting ears are damaged or deformed by collision, the entire motor end cover is easily scrapped. For this reason, we propose a combined motor end cover. Utility Model Content

[0011] Preferably, the motor end cover further comprises a through hole extending through the center thereof, and a bearing mounting seat fixedly arranged at the inner end of the motor end cover outside the through hole.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. In the utility model, the mounting ears that are engaged and installed in the slots in the motor end cover adopt a combined structure with the motor end cover body, so that after the mounting ears are damaged during use, the mounting ears can be conveniently replaced by disassembling the clamping ring at the inner end of the motor end cover, thereby avoiding the problem of the motor end cover being scrapped as a whole after the mounting ears of small parts on the motor end cover are damaged or deformed;

[0014] 2. In the present invention, the sealing ring installed inside the inner recess and the outer recess between the upper part of the clamping ring and the motor end cover can also ensure the sealing of the assembled motor end cover after installation, thereby avoiding the combined structure of the mounting ears from affecting the sealing of the motor end cover.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods. Embodiment 1

[0022] like Figure 1-3As shown, the present embodiment provides a combined motor end cover, including a motor end cover 100 and a replacement assembly 200, the motor end cover 100 also includes a through hole 101 extending through the center thereof, and a bearing mounting seat 102 fixedly arranged at the inner end of the motor end cover 100 outside the through hole 101, the replacement assembly 200 includes a slot 201 extending through the motor end cover 100, and a mounting ear 202 movably matched and installed in the slot 201, a fixing ring 203 is also welded and fixedly installed at the inner end of the motor end cover 100, an installation cavity 204 is also formed between the outer side of the fixing ring 203 and the motor end cover 100, a clamping ring 205 is also movably matched and installed in the installation cavity 204, the fixing ring 203 and the installation cavity The structures of 204 and the clamping ring 205 are both circular rings, the slots 201 and the mounting ears 202 are arranged in a ring shape, and the number of the slots 201 and the mounting ears 202 are both multiple groups. The replacement component 200 also includes the bayonet holes 206 that are opened on both sides of the fixing ring 203, and the clamping strips 207 that are welded and fixed on both sides of the inner end of the clamping ring 205 and match the bayonet holes 206. The replacement component 200 also includes the inner recess 208 and the outer recess 209 that are respectively opened on the inside and outside of the upper part of the motor end cover 100 and the clamping ring 205, and the sealing ring 210 that is movably matched and installed in the inner recess 208 and the outer recess 209. The replacement component 200 also includes the mounting holes 211 that are opened through the mounting ears 202.

[0023] Specifically, the motor refers to an electromagnetic device that realizes electric energy conversion or transmission according to the law of electromagnetic induction. The motor end cover 100 is a component on the upper end of the motor, which is mainly installed at the front end of the motor to ensure the sealing of the front end of the motor and the stable operation of the rotating shaft. The mounting ear 202 that is engaged and installed in the slot 201 in the motor end cover 100 adopts a combined structure with the motor end cover 100 body, so that after the mounting ear 202 is damaged during use, the mounting ear 202 can be easily replaced by disassembling the clamping ring 205 at the inner end of the motor end cover 100, thereby avoiding damage to the mounting ear 202 of the small component on the motor end cover 100 or The problem of the motor end cover 100 being scrapped as a whole after deformation.
