Description

Technical Field

[0001] The utility model relates to the technical field of speed reducers, and particularly relates to a wear-resistant speed reducer gear ring. Background Technique

[0002] A speed reducer is a relatively precise machine and also a power transmission mechanism. It has a wide variety of types and models, and different types have different uses. Currently, it is widely used in the mechanism for transmitting power and motion.

[0003] A speed reducer can reduce the rotation speed of the motor to the required rotation speed and obtain a mechanism with a larger torque. The gear ring plays an important role in the speed reducer. During rotation, due to the small gap between the gear ring and the housing of the speed reducer, a large rotational friction is generated, which easily causes the housing to be worn and heat generated by friction, resulting in a reduced service life of the housing.

[0015] Three beneficial effects

[0016] Compared with the prior art, the utility model provides a wear-resistant reducer gear ring, which has the following beneficial effects:

[0017] 1. This wear-resistant reducer gear ring is started by starting the motor, and then the connecting device is installed in front of the reducer. The rear end of the connecting device penetrates into the reducer to form a meshing fit with the gear ring, and can rotate as the gear ring is driven by the motor. The rotating positioning block is embedded in the inner side of the shell, and is slidably connected with the ring rail, so as to assist the positioning of the gear ring during the rotation process and prevent the gear ring from moving during operation.

[0018] 2. The wear-resistant reducer gear ring rotates on the inner side of the auxiliary body, and there is a gap between the gear ring and the inner wall of the shell by the auxiliary body, so that the outer wall of the gear ring will not rotate by rubbing against the inner wall of the shell, and the tough frame generates a hanging force on the wheel. The toughness of the frame makes it easy for the wheel to have a small position change due to the different pressures it receives after the wheel and the gear ring are pressed, so that the bearing has a flexible connection force outside the gear ring, thereby increasing the distance between the gear ring and the shell, reducing rotational friction, avoiding damage to the external frame device due to friction, and ensuring a longer service life of the shell.

The rear end of the connection device 4 is rotatably installed in front of the reduction device 3 and is rotationally fitted internally. The reduction device 3 includes a gear ring 31, a rotation positioning block 32, and an outer frame device 33. The rotation positioning block 32 is slidably connected to the inside of the outer frame device 33. The outer side of the gear ring 31 is fixedly connected with the rotation positioning block 32 and is rotationally fitted.

[0027] In addition, the rear end of the connecting cover 2 is embedded and connected to the rotation positioning block 32, and the front end of the connection device 4 is installed at the middle end of the gear ring 31 and is movably fitted.

[0028] In addition, the rear end of the outer frame device 33 is connected to the front end of the connecting cover 2. The gear ring 31 is cooperated with the motor 1 through the connecting cover 2. The central end of the connection device 4 is rotationally fitted with the gear ring 31.

[0029] Please refer to Figure 3-4 , a wear-resistant reducer gear ring, the rotation positioning block 32 includes an auxiliary body q1, a ring track q2, a placement track q3, and a housing q4. The ring track q2 and the housing q4 are an integral structure and are located on the inner side thereof. The placement track q3 is located on the inner side of the housing q4. The auxiliary body q1 is located above and below the ring track q2.

[0030] In addition, the ring gear 31 is loosely fitted on the inner side of the shell q4, the ring gear 31 passes through the placement channel q3, the rotation positioning block 32 is embedded in the shell q4, the rotation positioning block 32 is slidingly engaged with the ring rail q2, and the rotation of the ring gear 31 can be stably rotated in a ring shape through the sliding connection between the rotation positioning block 32 and the ring rail q2.

[0031] See also Figure 5 A wear-resistant reducer gear ring, the auxiliary body q1 includes a tough frame q11, a bearing q12, and a rotating wheel q13. The bearing q12 is connected with the tough frame q11 through and through, and the bearing q12 passes through the center of the rotating wheel q13 and rotates in cooperation. The rotating wheel q13 is movably matched with the tough frame q11 through the bearing q12.

[0032] In addition, one end of the frame q11 is embedded and connected to the shell q4, and the bearing q12 moves on the inner side of the shell q4. The bearing q12 and the two frames q11 cooperate as a group. There are seventeen groups, which are evenly distributed in the annular direction to control the distance between the outer side of the ring gear 31 and the shell q4.

[0033] In addition, the bearing q12 is loosely connected to the outer side surface of the ring gear 31 and rotates in coordination with it. The bearing q12 is a spherical block of nitrile rubber with high wear resistance. It rotates outside the ring gear 31 and rotates with it without hindering the rotation of the ring gear 31.

[0034] In summary, when in use, by starting the motor 1, the connecting device 4 is installed in front of the reduction device 3, and the rear end of the connecting device 4 penetrates into the reduction device 3, and forms a meshing match with the ring gear 31, and can rotate with the ring gear 31 driven by the motor 1.

When the ring gear 31 rotates on the inner side of the auxiliary body q1, it is in contact with the inner wall of the shell q4. There is a gap of auxiliary body q1, so that the outer wall of ring gear 31 will not rub against the inner wall of shell q4 during rotation, and the tough frame q11 generates a hanging force on the rotating wheel q13. Moreover, due to its own toughness, it is convenient for the rotating wheel q13 to have a small position change due to the different pressures after the rotating wheel q13 and the ring gear 31 are pressed. Therefore, the bearing q12 has a flexible connection force outside the ring gear 31, thereby increasing the distance between the ring gear 31 and the shell q4, reducing the rotational friction, and avoiding the damage of the external frame device 33 due to friction, thereby ensuring that the shell q4 has a longer service life.
