Description

Technical Field

[0001] This utility model relates to the field of speed reducer motor technology, and in particular to a speed reducer motor with a protective structure. Background Technology

[0002] A speed reducer motor is an integrated unit of a speed reducer and a motor. Due to its advantages of saving space, low energy consumption, superior performance, and reliability and durability, it is widely used in the speed reduction transmission mechanism of various mechanical equipment. During the operation of the speed reducer motor, a protective structure can be added to the end of the speed reducer motor to effectively prevent foreign objects from entering and external impacts from protecting the speed reducer motor body.

[0003] When installing a protective cover on a speed reducer motor, the threaded holes of the protective cover must be aligned with the threaded holes of the speed reducer motor. The movement of the protective cover needs to be manually restricted before it can be fixed with bolts. This operation is very inconvenient. If the manual handle loosens during the installation process, positioning deviations can easily occur, causing the protective cover to be installed off-center and unable to be accurately installed at the end of the speed reducer motor, thus reducing its protective effect on the speed reducer motor.

[0004] Therefore, to address the problem that existing gearbox motor protection mechanisms lack limit switches, which can easily lead to installation misalignment, a gearbox motor with a protective structure can be designed. Through precise positioning, a limit switch mechanism can be used to install a protective cover on the gearbox motor, making operation more convenient and effectively reducing the probability of installation misalignment. Utility Model Content

[0005] To overcome the problem that most gearbox motor protection structures lack limit mechanisms and require manual limiting, which can easily lead to installation misalignment.

[0006] The technical solution of this utility model is as follows: a reducer motor with a protective structure includes a reducer body and a motor body. The output end of the motor body is detachably installed on the input end of the reducer body. It also includes a protective shell, a limiting member, a fixing block, and a fixing groove. The output end of the reducer body is detachably installed with the protective shell. The protective shell is open at one end near the reducer body and is cylindrical. The limiting member is fixedly connected to the inner wall of the protective shell. A fixing groove is opened on the side of the limiting member near the reducer body. A fixing block is slidably connected in the fixing groove and is fixedly connected to the output end of the reducer body.

[0007] Preferably, when the reducer motor is installed with the protective structure, the fixing block at the end of the reducer body is aligned with the fixing groove opened in the center of the limiting member on the inner circumference of the protective shell, and the fixing block is pushed to slide in the fixing groove. The protective shell is fixed by the limiting mechanism, which is convenient to operate, reduces the probability of installation misalignment, and improves installation efficiency.

[0008] Preferably, the protective housing has an output port through the center, and the size of the output port is adapted to the output shaft of the reducer body.

[0009] Preferably, the protective shell has heat dissipation holes near the outer perimeter of the output port, and the heat dissipation holes are elongated.

[0010] Preferably, a first fixing member is fixedly connected to the periphery of the protective shell, and the first fixing member has a first fixing hole through it. A second fixing member is fixedly connected to the periphery of the protective shell away from the first fixing member. The second fixing member is hollow inside and has a protruding rib fixedly connected to it. The second fixing member has a second fixing hole through it, and the diameter of the second fixing hole is larger than that of the first fixing hole.

[0011] Preferably, a micro motor is fixedly installed on the inner wall of the protective shell. The micro motor is electrically connected to an electromagnet. The end of the electromagnet closest to the reducer body is magnetically connected to a permanent magnet. The permanent magnet is fixedly connected to a groove at the output end of the reducer body.

[0012] Preferably, a base is fixedly connected to the bottom of the reducer body, and a hydraulic damper is installed at the end of the base near the protective shell.

[0013] The beneficial effects of this utility model are:

[0014] Compared to traditional geared motors, the protective structure is fixed by a limiting mechanism, making operation more convenient and effectively avoiding the problem of displacement caused by manual limiting, thus reducing the probability of installation misalignment. The protective shell is installed magnetically, achieving quick disassembly and assembly, improving installation efficiency. The geared motor is cooled through heat dissipation holes, extending its service life, and a hydraulic damper is added to reduce vibration in the geared motor. Attached Figure Description

[0023] Please see Figure 2 and Figure 4 In this embodiment, the protective housing 5 has an output port 509 through the center. The size of the output port 509 is adapted to the output shaft of the reducer body 2. The output shaft of the reducer body 2 is connected to the mechanical equipment through the output port 509. The protective housing 5 has heat dissipation holes 508 near the output port 509. The heat dissipation holes 508 are elongated and are used to dissipate heat when the reducer motor is working, thus extending the service life.

[0024] Please see Figure 2 and Figure 3In this embodiment, a first fixing member 505 is fixedly connected to the periphery of the protective shell 5. The first fixing member 505 has a first fixing hole 510 through it. A second fixing member 506 is fixedly connected to the periphery of the protective shell 5 away from the first fixing member 505. The second fixing member 506 is hollow inside and has a protruding rib fixedly connected to it. The second fixing member 506 has a second fixing hole 511 through it. The diameter of the second fixing hole 511 is larger than that of the first fixing hole 510. The first fixing hole 510 on the first fixing member 505 and the second fixing hole 511 on the second fixing member 506 of the protective shell 5 are aligned with the reducer body 2. Bolts pass through the first fixing hole 510 and the second fixing hole 511 to fix the protective shell 5 to the outer end of the reducer motor. A micro motor is fixedly installed on the inner wall of the protective shell 5. The micro motor is electrically connected to an electromagnet 503. The end of the electromagnet 503 near the reducer body 2 is magnetically connected to a permanent magnet 504. The permanent magnet 504 is fixedly connected to the groove at the output end of the reducer body 2. In this embodiment, the permanent magnet 504 is made of neodymium iron boron material. The protective shell 5 is fixed to the outer end of the reducer motor by the attraction and fixation between the electromagnet 503 inside the protective shell 5 and the permanent magnet 504 at the end of the reducer body 2, which facilitates disassembly.

[0025] Please see Figure 1 and Figure 5 In this embodiment, a base 1 is fixedly connected to the bottom of the reducer body 2, and a hydraulic damper 4 is installed at one end of the base 1 near the protective shell 5. The vibration of the reducer motor is weakened by the hydraulic damper 4.

[0026] When installing the reducer motor, the motor body 3 is fixed to the reducer body 2 with bolts. The fixing block 502 at the end of the reducer body 2 is aligned with the fixing groove 507 opened in the center of the limiting member 501 on the inner circumference of the protective shell 5. The fixing block 502 is pushed to slide in the fixing groove 507, and the protective shell 5 is fixed by the limiting mechanism. At the same time, the electromagnet 503 inside the protective shell 5 is attracted and fixed to the permanent magnet 504 at the end of the reducer body 2, so as to ensure that the protective shell 5 is accurately positioned at the end of the reducer motor. The first fixing hole 510 on the first fixing member 505 and the second fixing hole 511 on the second fixing member 506 of the protective shell 5 are aligned with the reducer body 2. The protective shell 5 is fixed to the outer end of the reducer motor by bolts passing through the first fixing hole 510 and the second fixing hole 511. The output shaft of the reducer body 2 is connected to the mechanical equipment through the output port 509.

[0027] During operation, the reducer motor absorbs multi-directional vibrations through the hydraulic damper 4, keeping the reducer motor stable, and uses the heat dissipation holes 508 for heat dissipation, thus extending its service life.

[0028] Through the above steps, compared with the traditional reducer motor, the operation is more convenient by fixing the protective structure through the limiting mechanism, effectively avoiding the problem of displacement caused by manual limiting, reducing the probability of installation displacement, and achieving the effect of quick disassembly and assembly by magnetically installing the protective shell 5, improving installation efficiency. The reducer motor is cooled by the heat dissipation hole 508, extending its service life, and the hydraulic damper 4 is added to reduce the vibration of the reducer motor.
