Description

Technical Field

[0001] This utility model relates to the field of motor technology, and in particular to a variable frequency brake motor that is easy to disassemble. Background Technology

[0002] Manual rotation refers to the manual rotation of the shaft of a machine under certain working conditions for maintenance, inspection, or debugging. As a routine method for maintaining, inspecting, and debugging mechanical equipment, manual rotation is crucial for ensuring the normal operation of the equipment. To meet the needs of manual rotation, ordinary brake motors can achieve manual operation at the non-shaft extension end by extending the shaft and extending it out of the fan cover.

[0003] However, as a combination of variable frequency motor and brake motor, variable frequency brake motor has both speed regulation function and braking capability. However, in its design, the non-shaft extension end is often equipped with a fan for motor heat dissipation. Although this design improves the heat dissipation performance of the motor, it limits the lengthening of the shaft, making it impossible for the shaft to pass through the fan, thus making it impossible to realize manual operation of the non-shaft extension end.

[0004] The presence of the fan makes manual turning difficult. The usual method to meet the need for manual turning is to disassemble the entire fan. This is not only complicated to operate, but also requires disconnecting the wiring, which increases the complexity of the operation. Disassembly and installation are relatively difficult, especially when installing on site, which requires a lot of manpower and resources. Summary of the Invention

[0005] To address the above problems, this application provides a variable frequency brake motor that is easy to disassemble. The variable frequency brake motor has a fan cover at its non-shaft extension end, and a fan is housed within the fan cover. A sliding disassembly unit is provided between the fan cover and the motor housing. The sliding disassembly unit includes a locking groove on the motor housing, and a slide rail on one side of the locking groove. The slide rail includes a first slide rail and a second slide rail, which are connected. A positioning block is fixedly installed on the inner wall of the fan cover, and the positioning block can reciprocate along the slide rail. An adjustment window is provided on the fan cover.

[0006] In one embodiment, the first slide rail and the second slide rail are arranged along the axial direction of the variable frequency brake motor.

[0007] In one embodiment, both the fan cover and the motor housing are provided with locking holes, and locking rivets are provided in the locking holes.

[0008] In one embodiment, there are at least two sliding disassembly units, and adjacent sliding disassembly units have the same angle.

[0009] In one embodiment, the inner diameter of the fan cover is equal to the outer diameter of the motor housing.

[0010] In one embodiment, the fan housing is made of metal.

[0011] The beneficial effects of this utility model are as follows:

[0012] This application discloses a variable frequency brake motor that is easy to disassemble. The motor has a fan cover at its non-shaft extension end, a fan is housed within the fan cover, and a sliding disassembly unit is provided between the fan cover and the motor housing. The sliding disassembly unit includes a locking groove on the motor housing, a slide rail on one side of the locking groove, and the slide rail includes a first slide rail and a second slide rail. A positioning block is fixedly installed on the inner wall of the fan cover, and the positioning block can reciprocate along the slide rail. An adjustment window is provided on the fan cover. By incorporating a sliding disassembly unit, manual rotation of the fan shroud can be achieved simply by rotating the shroud and moving the positioning block to the first slide rail, followed by adjusting the window. This significantly simplifies the operation and reduces potential risks associated with disassembly. The second slide rail further streamlines the disassembly process, improving maintenance efficiency and reducing downtime caused by disassembly difficulties. Operators can easily rotate the shroud and move the positioning block to manually rotate the fan through the window, eliminating the need to disassemble the entire shroud. This saves considerable time and manpower, reduces operational complexity, and enhances work efficiency. Attached Figure Description

[0027] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0028] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0029] like Figure 1-5 As shown, a variable frequency brake motor that is easy to disassemble is provided, comprising a variable frequency brake motor 1, a fan cover 2 provided at the non-shaft extension end of the variable frequency brake motor 1, a fan provided inside the fan cover 2, a sliding disassembly unit 4 provided between the fan cover 2 and the motor housing 3, the sliding disassembly unit 4 including a locking groove 41 provided on the motor housing 3, a slide rail 42 provided on one side of the locking groove 41, the slide rail 42 including a first slide rail 421 and a second slide rail 422, the first slide rail 421 and the second slide rail 422 being connected, a positioning block 43 fixedly provided on the inner wall of the fan cover 2, the positioning block 43 being able to reciprocate along the slide rail 42, and an adjustment window 21 provided on the fan cover 2.

[0030] Specifically, in the initial state, such as Figure 4As shown, the fan housing 2 is securely installed by the engagement of a positioning block 43 on its inner wall with a locking groove 41 on the motor housing 3. The positioning block 43 is fully positioned in the locking groove 41 and is in a locked state. When it is necessary to manually rotate the motor shaft to check or adjust its operating status, the position of the positioning block 43 is changed by rotating the fan housing 2. First, the fan housing 2 is rotated so that the positioning block 43 slides out of the locking groove 41 and into the first slide rail 421. The first slide rail 421 causes the positioning block 43 to move back and forth along its path, thereby adjusting the position of the fan housing 2 relative to the motor housing 3. By moving the position of the positioning block 43 in the first slide rail 421, the position of the adjustment window 21 on the fan housing 2 can be adjusted. Figure 5 As shown, the adjustment window 21 is positioned directly opposite the crankshaft head 5. This allows the operator to directly access the crankshaft head 5 through the adjustment window 21 for manual cranking. When the fan housing 2 needs to be disassembled for maintenance or replacement, the positioning block 43 is moved from the first slide rail 421 to the second slide rail 422. The positioning block 43 can then continue sliding along the second slide rail 422 until the fan housing 2 is completely separated from the motor housing 3. The design of the second slide rail 422 ensures that the fan housing 2 can be removed smoothly and easily. By setting up the sliding disassembly unit 4, when manual rotation is required, the fan cover 2 can be simply rotated and the positioning block 43 moved to the first slide rail 421, and then the window 21 can be adjusted to achieve manual rotation. Unlike traditional designs, the entire fan cover does not need to be disassembled, which greatly simplifies the operation steps and reduces the potential risks caused by disassembly. By setting up the second slide rail 422, the disassembly of the fan cover 2 becomes smoother and easier, improving maintenance efficiency and reducing downtime caused by disassembly difficulties. Operators only need to easily rotate the fan cover 2 and move the positioning block 43 to achieve manual rotation directly through the adjustment window 21 without disassembling the entire fan cover 2, which greatly saves time and manpower, reduces the difficulty of operation, and improves work efficiency.

[0031] like Figure 1 As shown, the first slide rail 421 and the second slide rail 422 are arranged along the axial direction of the variable frequency brake motor 1.

[0032] Specifically, the axially arranged slide rail 42 simplifies the movement of the fan housing 2. Operators only need to move the fan housing 2 axially to perform cranking or disassembly operations, eliminating the need for complex rotation or tilting movements. Operators only need to move the fan housing 2 axially as instructed, significantly saving time and effort. Because the slide rail 42 is axially arranged, users can more accurately control the position of the fan housing 2 when moving it, thereby improving the precision and accuracy of the operation.

[0033] like Figure 4 ,5 As shown, both the fan cover 2 and the motor housing 3 are provided with locking holes, and locking rivets 6 are provided in the locking holes.

[0034] Specifically, locking holes and locking rivets 6 are provided on both the fan housing 2 and the motor housing 3. When the positioning block 43 is engaged in the locking groove 41 on the motor housing 3, a preliminary mechanical lock is formed between the fan housing 2 and the motor housing 3. After the positioning block 43 locks, the locking holes on the fan housing 2 and the motor housing 3 overlap. At this time, the locking rivet 5 can be inserted into these two overlapping locking holes to further securely lock the fan housing 2 and the motor housing 3. This double-locking design not only enhances the stability of the fan housing 2 but also improves the safety and reliability of the entire motor. When it is necessary to disassemble the fan housing 2, simply pull out the locking rivet 6 to release its locking effect, and then slide the positioning block 43 out of the locking groove 41 to easily remove the fan housing 2 from the motor housing 3. The double-locking design greatly enhances the connection stability between the fan housing 2 and the motor housing 3, preventing loosening or detachment due to vibration or external impact.

[0035] like Figure 1 As shown, there are at least two sliding disassembly units 4, and adjacent sliding disassembly units 4 have the same angle.

[0036] Specifically, multiple sliding disassembly units 4 form multiple support points between the fan cover 2 and the motor housing 3. These support points share the weight of the fan cover 2 and the vibration generated during operation, thereby enhancing the stability of the entire structure. The uniform distribution helps to reduce damage caused by stress concentration and further improves the stability of the structure.

[0037] like Figure 1 , 2 As shown, the inner diameter of the fan cover 2 is equal to the outer diameter of the motor housing 3.

[0038] Specifically, since the fan housing 2 and the motor housing 3 are in close contact, the sliding disassembly unit 4 can obtain more stable support when connecting the two, which helps to reduce the risk of the sliding disassembly unit becoming loose or damaged due to vibration or external impact, thereby improving the stability of the entire structure. The close contact also helps to enhance the sealing performance of the sliding disassembly unit, thereby preventing external impurities from entering the motor.

[0039] This application discloses a variable frequency brake motor that is easy to disassemble. It includes a variable frequency brake motor 1, a fan cover 2 at the non-shaft extension end of the variable frequency brake motor 1, a fan inside the fan cover 2, a sliding disassembly unit 4 between the fan cover 2 and the motor housing 3, the sliding disassembly unit 4 including a locking groove 41 on the motor housing 3, a slide rail 42 on one side of the locking groove 41, the slide rail 42 including a first slide rail 421 and a second slide rail 422, a positioning block 43 fixedly installed on the inner wall of the fan cover 2, the positioning block 43 can reciprocate along the slide rail 42, and an adjustment window 21 is provided on the fan cover 2. By setting up the sliding disassembly unit 4, when manual rotation is required, the fan cover 2 can be simply rotated and the positioning block 43 moved to the first slide rail 421, and then the window 21 can be adjusted to achieve manual rotation. Unlike traditional designs, the entire fan cover does not need to be disassembled, which greatly simplifies the operation steps and reduces the potential risks caused by disassembly. By setting up the second slide rail 422, the disassembly of the fan cover 2 becomes smoother and easier, improving maintenance efficiency and reducing downtime caused by disassembly difficulties. Operators only need to easily rotate the fan cover 2 and move the positioning block 43 to achieve manual rotation directly through the adjustment window 21 without disassembling the entire fan cover 2, which greatly saves time and manpower, reduces the difficulty of operation, and improves work efficiency.
