Description

Technical Field

[0001] This utility model relates to the field of motor technology, and in particular to a modular motor housing. Background Technology

[0002] Modular motor housings refer to standardized and interchangeable motor housing designs. They typically employ a modular design, facilitating disassembly, assembly, and maintenance, as well as component replacement and repair. This design allows the motor housing to adapt to different application scenarios and requirements, improving production efficiency and flexibility.

[0003] In mining and other high-frequency vibration or high-impact working environments, the existing modular motor housing is prone to loosening or damage due to vibration, requiring replacement of the housing modules. The connection surfaces of the housing undergo micro-wear due to resonance during operation. After the motor housing is replaced, gaps are easily created when the new module is fitted with the old module due to wear from use. These gaps result in insufficient rigidity between the modules, which may cause additional displacement due to vibration during motor operation, exacerbating the wear of the components.

[0004] Gaps can cause uneven stress on bolts or fasteners, and local stress concentration can easily lead to overload damage to the connectors. After long-term use, problems such as stripped threads and broken bolts may occur. To address these issues, we provide a modular motor housing. Utility Model Content

[0005] The technical problem this utility model aims to solve is to provide a modular motor housing to address the issue that existing modular motor housings are prone to loosening or damage due to vibration in high-frequency vibration or high-impact working environments such as mining, requiring replacement of the housing modules. Furthermore, the connection surfaces of the housing experience micro-wear due to resonance during operation. After replacing the motor housing, gaps easily form when the new module is fitted with the old module due to wear from previous use. These gaps result in insufficient rigidity between the modules, which may cause additional displacement due to vibration during motor operation, exacerbating the wear of the components.

[0006] To solve the problems mentioned above, this utility model is implemented through the following technical solution.

[0007] A modular motor housing includes: an outer shell;

[0008] A connecting groove is formed on the end face of the outer shell, and a gasket is connected inside the connecting groove;

[0009] Flange 1 is fixedly connected to the outer side of the end of the housing, and a groove is provided inside the flange 1;

[0010] Flange 2 is fixedly connected to the outer side of the end of the end cover, and a protrusion that matches the groove is fixedly connected inside flange 2.

[0011] Furthermore, the washer is convex, and the protruding part of the washer matches the connecting groove.

[0012] Furthermore, an O-ring is connected inside the groove, and one side of the groove is inclined inward.

[0013] Furthermore, one side of the protrusion is inclined, and the protrusion matches the size of the groove.

[0014] Furthermore, two blind holes are formed on the surface of the flange, and the central axis of the blind holes is located on the same diameter of the flange. Two connecting holes are also formed on the surface of the flange, and the central axis of the connecting holes is located on the same diameter of the flange.

[0015] Furthermore, the surface of the second flange has two through holes and two connecting holes. The through holes are opposite to the blind holes, and both the through holes and the blind holes are tapered. The second connecting hole is opposite to the first connecting hole.

[0016] Furthermore, the blind hole and the through hole are connected by a tapered pin, and the first connecting hole and the second connecting hole are connected by bolts.

[0017] Furthermore, the tapered pin is tapered, and the outer side of the tail end of the tapered pin is provided with a threaded groove, and the outer side of the threaded groove is provided with a nut that mates with the threaded groove.

[0018] This utility model provides a modular motor housing. Compared with the prior art, it has the following advantages:

[0019] 1. By setting a connecting groove and a gasket, the gasket has a certain elastic support, which can absorb the running vibration and reduce the wear of the contact surface during operation. The gasket can be replaced after wear during use without replacing the entire housing. At the same time, the new gasket can fit the motor housing and the new housing module under its own elastic force, reducing the gap between the old housing and the new housing module, avoiding problems such as insufficient connection rigidity between modules caused by the gap, which is conducive to the long-term use of the motor housing.

[0020] 2. By setting blind holes, through holes, and tapered pins, the tapered pins are inserted into the blind holes and through holes. The tapered surface of the tapered pins matches the tapered surfaces in the blind holes and through holes, and the tapered pins play a certain guiding role. At the same time, they limit the axial and radial displacement of the connecting surfaces, and realize the positioning and fastening functions. This effectively improves the installation accuracy, reduces errors, avoids gaps during installation, and reduces the risk of wear. Attached Figure Description

[0028] The present invention will be further described below with reference to specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of protection of the present invention.

[0029] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0030] Reference Figures 1-3 A modular motor housing is provided, including an outer shell 1; a connecting groove 101 is formed on the end face of the outer shell 1, and a washer 102 is connected inside the connecting groove 101. The washer 102 is convex and the protruding part of the washer 102 matches the connecting groove 101.

[0031] The washer 102, which is snapped into the end of the housing 1 by the connecting groove 101, is located on the end face of the housing 1. This can reduce the wear generated when the end of the housing 1 is connected to the end cover 3. At the same time, the washer 102 can be disassembled and replaced after wear occurs.

[0032] Flange 1 2 is fixedly connected to the outer side of the end of the housing 1. Flange 2 2 has a groove 201 inside. Flange 2 4 is fixedly connected to the outer side of the end of the end cover 3. Flange 2 4 has a protrusion 401 that matches the groove 201 inside.

[0033] Specifically, an O-ring 202 is connected inside the groove 201. One side of the groove 201 is inclined inward, and one side of the protrusion 401 is inclined. The protrusion 401 and the groove 201 are of the same size.

[0034] Both ends of the outer casing 1 are connected to end caps 3. The outer casing 1 and end caps 3 are connected by flange 1 2 and flange 2 4. When connecting, the protrusion 401 is aligned with the groove 201. Since the groove 201 is set with a slope, it has a certain guiding effect during connection, which facilitates quick connection and improves the connection accuracy. The O-ring 202 inside the groove 201 protects the contact surface between the protrusion 401 and the groove 201 and reduces wear.

[0035] Reference Figures 1-5 Flange 12 has two blind holes 203 on its surface. The central axis of the blind holes 203 is located on the same diameter of flange 12. Flange 12 also has two connecting holes 204 on its surface. The central axis of the connecting holes 204 is located on the same diameter of flange 12. Flange 24 has two through holes 402 and two connecting holes 403 on its surface. The through holes 402 and blind holes 203 are opposite each other and are both tapered. The connecting holes 403 and connecting holes 204 are opposite each other.

[0036] Specifically, the blind hole 203 and the through hole 402 are connected by a tapered pin 5, and the connecting hole 1 204 and the connecting hole 2 403 are connected by a bolt 6. The tapered pin 5 is tapered, and the outer side of the tail end of the tapered pin 5 is provided with a threaded groove 501. The outer side of the threaded groove 501 is provided with a nut 502 that mates with the threaded groove 501.

[0037] The two blind holes 203 in flange 12 do not penetrate the entire flange 12, while the through hole 402 penetrates the entire flange 24. The blind holes 203 and the through hole 402 are tapered holes that can mate with the tapered pin 5. After the tapered pin 5 is inserted into the tapered holes of flange 12 and flange 24, the taper surface of the tapered pin 5 mates with the tapered hole, restricting the axial and radial displacement of flange 12 and flange 24, and simultaneously achieving positioning and fastening functions. The connecting hole 1204 and the connecting hole 2203 are of the same size and are fixed by bolts 6 during connection.

[0038] Working principle: Both ends of the outer casing 1 are connected to end caps 3. The outer casing 1 and the end caps 3 are connected by flange 1 2 and flange 2 4. The gasket 102, which is snapped into the end of the outer casing 1 by the connecting groove 101, is located on the end face of the outer casing 1. This reduces wear caused by contact between the end of the outer casing 1 and the end cap 3. The gasket 102 is removable and can be replaced after wear. During connection, the protrusion 401 is aligned with the groove 201. Since the groove 201 is inclined, it has a certain guiding effect during connection, which facilitates quick connection. To improve the connection accuracy, the O-ring 202 inside the groove 201 protects the contact surface between the protrusion 401 and the groove 201. Then, the tapered pin 5 is inserted into the tapered hole of the rear flange 1 2 and flange 2 4, and is connected and fixed with the threaded groove 501 using the nut 502. The fit between the tapered surface of the tapered pin 5 and the tapered hole restricts the axial and radial displacement of flange 1 2 and flange 2 4, and at the same time realizes the positioning and fastening functions. The connecting hole 1 204 and connecting hole 2 403 are of the same size and are fixed by bolts 6 during connection.
