Description

Technical Field

[0001] The utility model relates to the technical field of planetary gear reducers, in particular to a protective structure of a planetary gear reducer. Background Art

[0002] The main features of planetary gear reducer are small size, large load-bearing capacity, stable operation, and it is a power transmission mechanism that uses a gear speed converter to reduce the number of revolutions of the motor to the required number of revolutions and obtain a larger torque mechanism; however, due to the small size of some planetary gear reducers, when there is a scratch on the surface, it will directly hurt itself. If the scratch is strong, it is also easy to cause a certain impact on the internal structure of the reducer. For this reason, we propose a protective structure for planetary gear reducer. Utility Model Content

[0003] In view of the problems in the prior art, the utility model provides a planetary gear reducer protection structure.

[0004] The technical solution adopted by the utility model to solve the technical problem is a planetary gear reducer protection structure, comprising a plate seat, the outer wall surface of the plate seat is equipped with a reducer body, and the outer wall surface of the plate seat is equipped with an annular shell located on the outer periphery of the reducer body by screws, and the outer periphery of the annular shell is screwed and installed with a ring cover that is matched and connected with the reducer body;

[0005] The outer peripheral surface of the ring shell and the outer peripheral surface of the ring cover are both coated with a reinforcement layer, and the outer peripheral surface of the reinforcement layer is coated with a wear-resistant layer.

[0006] By adopting the above technical solution, before installing the planetary gear reducer, the ring shell is first installed on the plate seat surface at one side end of the reducer body by screws, and then the threads on the ring cover and the surface of the ring shell are screwed together, so that the ring cover can cover and protect the outer periphery of the reducer body, and the ring cover and the ring shell cooperate with each other to facilitate the establishment of a layer of protection on the outer periphery of the reducer body, so that when friction occurs, it can be blocked, which is convenient to reduce the impact of the friction on the reducer body, so that the planetary gear reducer can be operated more stably and safely in the future;

[0007] When the ring shell and the ring cover are in operation, the reinforcing layer on the surface of the ring shell and the ring cover is a chrome-plated layer, which is convenient for improving the strength and corrosion resistance between the two. At the same time, the wear-resistant layer is a ceramic wear-resistant layer, which is convenient for reducing the direct scratch damage caused by friction, thereby improving the protective performance of the ring shell and the ring cover.

[0008] Specifically, a silicone layer for buffering is bonded to the inner periphery of the ring shell and the ring cover, and a sound insulation cotton layer located at the outer periphery of the reducer body is bonded to the inner periphery of the silicone layer.

[0009] By adopting the above technical scheme, the silicone layer has a certain elasticity and buffering performance, which is convenient for buffering the impact force when the ring shell and the ring cover collide, thereby reducing the impact on the reducer body. At the same time, the sound insulation cotton layer is convenient for providing a certain noise reduction performance, so that the noise generated inside the reducer body is alleviated to a certain extent.

[0010] Specifically, a clamping strip for connection is integrally constructed on the inner circumference of one end of the ring cover away from the ring shell, and a rubber seat that is closely connected to the outer circumference of the reducer body is mounted on the outer circumference of the clamping strip.

[0011] By adopting the above technical solution, the rubber seat and the clamping strip are clamped with each other, which is convenient for disassembly and assembly, and can protect the end of the ring cover close to the reducer body, so as to facilitate buffering when friction occurs.

[0012] Specifically, the outer peripheral surface of the ring cover is provided with concave holes for rotation, and there are multiple groups of concave holes.

[0013] By adopting the above technical solution, the concave hole makes it easier to disassemble and assemble the ring cover.

[0014] Specifically, a protective rubber ring is bonded to the side of the reducer body that is in contact with the ring cover.

[0015] By adopting the above technical solution, the rubber ring has a certain elasticity, which is convenient for supporting the side where the ring cover and the reducer body are in contact with each other, and convenient for providing a certain buffering performance when the ring cover is rubbed.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] 1. The technical solution of the present application adopts the design of the reducer body, the ring shell and the ring cover. Before installing the planetary gear reducer, the ring shell is first installed on the plate seat surface at one side end of the reducer body by screws, and then the threads on the surface of the ring cover and the ring shell are screwed together, so that the ring cover can cover and protect the outer periphery of the reducer body, and the ring cover and the ring shell cooperate with each other to facilitate the establishment of a layer of protection on the outer periphery of the reducer body, so that when friction occurs, it can be blocked, which is convenient to reduce the impact of the friction on the reducer body, so that the planetary gear reducer can operate more stably and safely in the future.

[0018] 2. The technical solution of the present application adopts the design of a reinforcing layer and a wear-resistant layer. When the ring shell and the ring cover are in operation, the reinforcing layer on the surface of the ring shell and the ring cover is a chrome-plated layer, which is convenient for improving the strength and corrosion resistance between the two. At the same time, the wear-resistant layer is a ceramic wear-resistant layer, which is convenient for reducing the direct scratch damage caused by friction, thereby improving the protective performance of the ring shell and the ring cover.

At the same time, the sound insulation cotton layer 8 is convenient for providing a certain noise reduction performance, so that the noise generated inside the reducer body 2 is alleviated to a certain extent.
