Abstract
Description
Technical Field
[0001] This invention relates to the field of motor heat dissipation technology, specifically to a motor with an easily detachable heat dissipation structure. Background Technology
[0002] Medium-sized motors have relatively long rotors, and the area where the rotor meets the stator generates a lot of heat. The heat generated during the operation of the motor relies on the swirling air generated by the rotor to dissipate the heat. However, the heat cannot be carried away in time during the operation of medium-sized motors, causing the motor temperature to rise too quickly. Currently, the air-cooling heat dissipation devices used for motors have fixed structures, which are very inconvenient to install and remove, resulting in high maintenance costs and initial installation costs.
[0003] According to patent CN107591942A, a motor with an easily detachable heat dissipation structure includes a main housing, a stator fixedly connected inside the main housing, a main drive shaft extending transversely through the main housing, a rotor fitted on the main drive shaft to cooperate with the stator, a side cooling fan on the right side of the main drive shaft, a circular internal threaded through hole on the right side of the main housing, and a side sealing cover for closing the internal threaded through hole on the right side of the main housing. The side sealing cover is screwed into the internal threaded through hole by a left external threaded connecting ring and is threadedly connected and fixed to the main housing.
[0004] The inventors have discovered that at least the following problems remain unresolved in the prior art: the single method of fixing the main unit housing and the sealing cover by threading them together in the prior art has several drawbacks. First, the motor will vibrate during operation, and after long-term use, the sealing cover may loosen. Second, it is inconvenient to unscrew the sealing cover during disassembly and maintenance.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0015] 1. This invention, through the combination of a main drive shaft, a fixed platform, exhaust fan blades, and a vent, enables the exhaust fan blades to rotate during motor operation, accelerating airflow within the outer casing and automatically dissipating heat from the rotor.

The second spring's elasticity pushes the fixing pin through the first and second fixing grooves, facilitating the fixed connection between the outer casing and the connecting shell. Through the combination of a limiting plate and a third spring, when the fixing pin is pushed into the slide groove, the third spring's elasticity pushes the connecting sleeve to separate from the connecting shell, simultaneously separating the exhaust fan blades from the main drive shaft, facilitating the disassembly and maintenance of the exhaust fan blades.
[0016] 2. Through the combination of rotating groove, ball bearing, rotating plate and rotating rod, the main drive shaft can drive the exhaust fan blades on the outside of the fixed platform to rotate stably inside the connecting shell, avoiding interference between the fixed platform and the inner wall of the connecting shell during the rotation process.
[0017] 3. The present invention uses a limiting groove and a limiting block to slide together, which can limit and fix the fixed platform on the outside of the main drive shaft, so that the exhaust fan blades can be driven to rotate during the rotation of the main drive shaft, and at the same time facilitate the subsequent disassembly and maintenance of the exhaust fan blades.

The right side of the fixed platform 18 is provided with an annular rotating groove 42. The ball bearing 43 is movably connected inside the rotating groove 42. The main drive shaft 12 can drive the exhaust fan blade 19 on the outside of the fixed platform 18 to rotate stably in the connecting shell 2, avoiding interference between the fixed platform 18 and the main drive shaft 12 and the inner wall of the connecting shell 2 and the adjusting block 23 during rotation.
[0031] The disassembly mechanism includes a third spring 5 and a limiting plate 51. The third spring 5 is sleeved on the outside of the main drive shaft 12. The limiting plate 51 is installed through the right side of the main drive shaft 12. The third spring 5 is placed between the limiting plate 51 and the fixed platform 18. When the fixed pin 33 is pushed into the slide groove 31, the elastic force of the third spring 5 can push the connecting sleeve 15 to separate from the connecting shell 2, which facilitates the disassembly of the connecting shell 2. At the same time, it can push the exhaust fan blade 19 to separate from the main drive shaft 12, which facilitates the disassembly and maintenance of the exhaust fan blade 19.
[0032] In an optional embodiment, limit blocks 44 are fixedly installed on the inner walls of the front and rear sides of the fixed platform 18, and limit grooves 45 are horizontally opened on the front and rear sides of the right end of the main drive shaft 12, with the limit blocks 44 and the limit grooves 45 slidably connected.
[0033] It should be noted that the limiting groove 45 can limit the fixed platform 18 on the outside of the main drive shaft 12, so that the main drive shaft 12 can drive the exhaust fan blade 19 to rotate during rotation, and at the same time facilitate the subsequent disassembly and maintenance of the exhaust fan blade 19.
[0034] In an optional embodiment, the outer side of the ball 43 is fitted against the inner wall of the connecting shell 2, and the right end of the main drive shaft 12 is fitted against the left side of the rotating plate 4.
[0035] It should be noted that during the rotation of the main drive shaft 12, it can drive the exhaust fan blade 19 on the outside of the fixed platform 18 to rotate stably inside the connecting shell 2.
[0036] In an optional embodiment, a filter screen 17 is fixedly connected to the left inner wall of the housing 1 by screws, and the filter screen 17 is matched with the size of the vent 14.
[0037] It should be noted that by installing the filter screen 17, the air dust entering the housing 1 can be filtered to avoid affecting the use of the stator 11 and rotor 13.
[0038] In an optional embodiment, the groove 31 is sized to match the fixing pin 33, and the fixing pin 33 is sized to match the second fixing groove 25 and the first fixing groove 16.
[0039] It should be noted that the slide 31 can accommodate the fixing pin 33, thus preventing the fixing pin 33 from being too large and affecting the stability of the moving block 3 in the connecting groove 22.
[0040] In an optional embodiment, guide grooves 61 are horizontally provided above and below the adjusting block 23, and guide rods 6 are slidably connected inside the guide grooves 61. The two ends of the guide rods 6 are fixedly connected to the inside of the two sides of the adjusting grooves 21.

[0042] In an optional embodiment, a first spring 26 is sleeved on the outside of the guide rod 6, and the first spring 26 is sized to match the guide groove 61.
[0043] It should be noted that the elastic force of the first spring 26 can push the adjusting block 23 to move to the left and reset within the adjusting groove 21.
