Description

Technical Field

[0001] The utility model belongs to the technical field of motor rollers, and in particular relates to a connection structure between a motor roller and an end cover. Background Art

[0002] The drum motor is a driving device that installs the motor inside the drum body. It has the characteristics of compact structure, small space occupation, high transmission efficiency, good sealing, etc. The drum motor can be used as the power source of belt conveyor and is widely used in various industries.

[0003] The connection between the drum and the end cover is one of the important processes in the drum motor packaging and is an important link that can directly affect the quality of the drum motor.

[0004] Traditionally, the packaging of the roller and the end cap is mostly fixed by glue. The use of glue not only requires waiting for the glue to solidify, prolonging the production time and reducing the production efficiency, but also the glue is not only expensive, but also requires manual operation, resulting in unavoidable labor costs and material costs. Therefore, a solution is needed to solve the above problems.

[0005] It should be noted that the above contents belong to the technical knowledge of the inventor and do not necessarily constitute prior art. Utility Model Content

[0006] In order to solve the above problems, the purpose of the utility model is to provide a connection structure between the motor drum and the end cover which is fixed by cooperating with the end cover through a deformed drum opening, thereby replacing the glue fixing method.

[0007] To achieve the above-mentioned purpose, the utility model proposes a connection structure between a motor drum and an end cover, comprising a hollow drum and an end cover, wherein the end cover comprises two groups, and the two end covers are respectively covered at the two ends of the drum, and a plurality of grooves are arranged at the two ends of the drum along the inner wall of the drum, and the end cover is provided with a recess along the circumference of the end cover, and the openings on both sides of the drum are deformed toward the center of the drum.

[0008] In one example, the channel is a plurality of axially arranged strip-shaped grooves, and the strip-shaped grooves are arranged at intervals along the circumferential direction of the inner wall of the drum.

[0009] In one example, inner walls on both sides of the drum are further provided with concave rings, which are located at the groove and separate the groove into a first groove and a second groove.

[0010] In one example, the roller is concentrically arranged with the end cover.

[0011] In one example, the end cover includes a cover portion and a barrel portion, the cover portion has a diameter greater than an inner diameter of the drum, and the barrel portion has a diameter the same as the inner diameter of the drum.

[0012] In one example, the recess is located in the cylindrical portion, and the width of the recess is the same as that of the first groove.

[0013] In one example, the opening of the drum abuts against the cover portion of the end cover.

[0014] The connection structure between the motor drum and the end cover proposed by the utility model can bring the following beneficial effects:

[0015] 1. By setting a groove on the inner wall of the drum, the friction of the end cover in the drum is increased, the end cover is prevented from rotating circumferentially in the drum, and the stability of the fixed connection is improved;

[0016] 2. Through the deformation of the drum opening and the concave ring, the lower boss of the concave part of the end cover is embedded in the concave ring to prevent the end cover from axial movement in the drum, thereby completing the fixed connection between the end cover and the drum;

[0017] 3. The roller and the end cover are fixed by structure instead of traditional glue, which can effectively save labor cost and material cost and improve production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] like Figure 1 to Figure 5As shown, an embodiment of the utility model proposes a connection structure between a motor drum 1 and an end cover 2, characterized in that it includes a hollow drum 1 and an end cover 2, the end cover 2 includes two groups, the end covers 2 are respectively covered at the two ends of the drum 1, a plurality of grooves 11 are provided at the two ends of the drum 1 along the inner wall of the drum 1, and the end cover 2 is provided with a recess 21 along the circumference of the end cover 2. When the end cover 2 is covered in the drum 1, the circumference of the end cover 2 abuts against the groove 11 on the inner wall of the end cover 2 to prevent circumferential rotation, and the openings on both sides of the drum 1 are deformed toward the center of the drum 1.

[0030] The shrinking process causes the openings on both sides of the drum 1 to deform toward the center of the drum 1 , so that the openings on both sides of the drum 1 abut against the end cover 2 and deform toward the side wall of the end cover 2 , thereby enhancing the stability of the connection and completing the fixation of the end cover 2 in the drum 1 .

[0031] Specifically, the groove 11 is a plurality of axially arranged strip grooves 111, which are arranged at intervals along the circumferential direction of the inner wall of the drum 1. By arranging the strip grooves 111 on the inner wall of the drum 1, the friction between the drum 1 and the end cover 2 can be increased, thereby improving the connection stability of the end cover 2 on the drum 1.

[0032] Specifically, concave rings 12 are formed on the inner walls of both sides of the drum 1 . The concave rings 12 are located at the groove 11 and separate the groove 11 into a first groove 112 and a second groove 113 .

[0033] Specifically, the drum 1 and the end cover 2 are concentrically arranged.

[0034] Specifically, the end cover 2 includes a cover portion 22 and a barrel portion 23 . The diameter of the cover portion 22 is larger than the inner diameter of the drum 1 , and the diameter of the barrel portion 23 is the same as the inner diameter of the drum 1 .

[0035] Specifically, the recess 21 is located in the barrel portion 23, and the width of the recess 21 is the same as that of the first groove 112. When the opening of the drum 1 is deformed, the barrel portion 23 is embedded in the concave ring 12 through the boss generated by the recess 21, preventing the end cover 2 from axially rotating in the drum 1 and preventing the end cover 2 from escaping from the drum 1.

[0036] Specifically, the opening of the drum 1 abuts against the cover portion 22 of the end cover 2 to ensure a fixed connection between the drum 1 and the end cover 2 and prevent failure of the connection between the end cover 2 and the drum 1 .

[0037] Working principle: The end covers are placed on the openings on both sides of the drum, so that the openings of the drum and the cover of the end covers abut against each other. The strip grooves on the inner wall of the drum increase the friction between the drum body and the inner wall of the drum, thereby preventing the end covers from rotating circumferentially in the drum.

[0038] When the end cover is installed in the drum, the openings on both sides of the drum are deformed toward the center of the drum through the shrinking process, so that the openings on both sides of the drum are deformed toward the drum body while abutting the end cover, so that the boss generated by the recessed part of the drum body is embedded in the recessed ring, preventing the end cover from axial rotation in the drum and preventing the end cover from falling out of the drum, thereby enhancing the stability of the connection and completing the fixation of the end cover in the drum.

[0039] Each embodiment in this specification is described in a progressive manner, and the same or similar parts between the embodiments can be referred to each other, and each embodiment focuses on the differences from other embodiments. In particular, for the system embodiment, since it is basically similar to the method embodiment, the description is relatively simple, and the relevant parts can be referred to the partial description of the method embodiment.

[0040] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
