Description

Technical Field

[0001] The utility model relates to the technical field of planetary reducers, in particular to a shock-absorbing planetary reducer. Background Art

[0002] Planetary reducers are widely used industrial products that can reduce the speed of motors and increase output torque. Planetary reducers can be used as supporting components in industries such as lifting, excavation, transportation, and construction. Planetary reducers need to be assembled with motors. During daily use of planetary reducers, they often have problems with shaking and vibration.

[0003] The reasons for the obvious vibration of the planetary reducer during operation are:

[0004] The connection between the connecting plate of the planetary reducer and the motor is loose. When the planetary reducer works for a long time, the connecting plate may become loose, which will cause the reducer to vibrate. Therefore, a new shock-absorbing planetary reducer is proposed to solve the above problem. Utility Model Content

[0005] The purpose of the present invention is to solve at least one of the above technical deficiencies.

[0006] Therefore, one purpose of the utility model is to provide a shock-absorbing planetary reducer to solve the problems mentioned in the background technology and overcome the deficiencies in the prior art.

[0007] In order to achieve the above-mentioned purpose, an embodiment of the utility model provides a shock-absorbing planetary reducer, comprising a body, an output shaft, a shaft key and a flange joint; the output end of the body is fixedly connected to the output shaft, the output shaft is embedded with a shaft key, and the tail end of the body is fixedly connected to the flange joint;

[0008] One side of the flange joint is fixedly connected to a joint plate by means of a hexagon socket screw, one side of the joint plate is fixedly connected to a motor, and the output end of the motor is plugged into the tail end interface of the fuselage;

[0009] A gasket is sandwiched between the joint plate and the flange joint, and positioning holes are provided on the front of the flange joint and the back of the joint plate. A hydraulic pin is inserted into the positioning hole, and a hydraulic sleeve is movably connected to the outer surface of the hydraulic pin, and a valve port is fixedly connected to the outer surface of the hydraulic sleeve;

[0012] Adopting the above technical solution: This application proposes a new type of planetary reducer. A planetary reducer is a common mechanical transmission device, and its main function is to reduce the speed of a high-speed rotating input shaft and increase the torque output at the same time. The working principle of the planetary reducer is realized through the movement of planetary gears. The interior of the planetary reducer is composed of a sun gear, a planetary gear, a planet carrier and an inner ring gear. The sun gear is the input shaft, the inner ring gear is the output shaft, and the planetary gear is connected to the sun gear and the inner ring gear through the planet carrier. When the sun gear rotates, the planetary gear and the planet carrier will also rotate, but the movement direction of the planetary gear is opposite to that of the sun gear. At the same time, the gear transmission between the planetary gear and the planet carrier will also cause the inner ring gear to rotate, thereby realizing the movement of the output shaft.

[0013] Preferably, any of the above solutions is that the gasket is made of rubber and has a thickness of 0.5-1 cm.

[0014] Preferably, in any of the above schemes, the diameter of the positioning hole is the same as the diameter of the hydraulic pin, and the positioning hole is located next to the corresponding screw hole.

[0015] The above technical solution is adopted: the planetary reducer and the motor are connected through a flange joint, hexagon socket screws, and a joint plate. The output end of the motor is plugged into the tail end of the planetary reducer to achieve power output.

[0016] By adopting the above technical solution, the gasket plays the role of sealing, lining and buffering.

[0017] Preferably, any of the above schemes is that a sealing gasket is provided at the active connection between the hydraulic pin and the hydraulic sleeve, a sealing cap is threadedly connected to the end of the valve port, a sealing ring is provided at the end of the valve port, and hydraulic oil is provided inside the hydraulic sleeve.

[0018] The above technical solution is adopted: the core structure of this device is: positioning hole, hydraulic pin, hydraulic sleeve, valve port, U joint, one-way valve. The core advantages of this device are: improve the flange joint of the planetary reducer and the joint plate of the motor, design the positioning hole structure, install the U joint after tightening the hexagon socket screw, align the hydraulic pin with the positioning hole, fill the hydraulic oil into the hydraulic sleeve through the one-way valve, push the hydraulic pin out, and tighten it again from both sides of the joint plate and the flange joint using the hydraulic structure, i.e. the hydraulic sleeve and hydraulic pin structure. Even if the hexagon socket screw is loose, the hydraulic sleeve and hydraulic pin structure can be used in conjunction with the positioning hole to clamp and fix the joint plate and the flange joint to prevent it from loosening, thereby effectively preventing the planetary reducer from shaking and vibrating, thereby achieving the purpose of structural stability, shock absorption and shockproof of the planetary reducer.

[0019] Preferably, any of the above schemes is that a rib plate is fixedly connected to the inner side of the bending part of the U-joint, and the one-way valve can only allow oil to enter but not to discharge oil.

[0020] Compared with the prior art, the advantages and beneficial effects of the utility model are:

[0035] Embodiment 1: The back of the flange joint 4 is provided with a screw hole adapted to the hexagon socket screw, and the joint plate 6 and the motor 7 are an integrated structure. The present application proposes a new planetary reducer. A planetary reducer is a common mechanical transmission device, and its main function is to reduce the speed of the high-speed rotating input shaft and increase the torque output at the same time. The working principle of the planetary reducer is realized through the movement of the planetary gears. The interior of the planetary reducer is composed of a sun gear, a planetary gear, a planetary carrier and an inner gear ring. The sun gear is the input shaft, the inner gear ring is the output shaft, and the planetary gear is connected to the sun gear and the inner gear ring through the planetary carrier. When the sun gear rotates, the planetary gear and the planetary carrier will also rotate, but the movement direction of the planetary gear is opposite to that of the sun gear. At the same time, the gear transmission between the planetary gear and the planetary carrier will also cause the inner gear ring to rotate, thereby realizing the movement of the output shaft 2. The material of the gasket 8 is rubber, and the thickness of the gasket 8 is 0.5-1 cm.

[0036] Embodiment 2: The diameter of the positioning hole 9 is the same as that of the hydraulic pin 10, and the positioning hole 9 is located next to the corresponding screw hole.

[0037] The working principle of the utility model is as follows:

[0038] S1. The interior of the planetary reducer consists of a sun gear, planet gears, a planet carrier and an inner gear ring. The sun gear is the input shaft, the inner gear ring is the output shaft, and the planet gears are connected to the sun gear and the inner gear ring through the planet carrier. When the sun gear rotates, the planet gears and the planet carrier will also rotate, but the direction of movement of the planet gear is opposite to that of the sun gear. At the same time, the gear transmission between the planet gear and the planet carrier will also cause the inner gear ring to rotate, thereby realizing the movement of the output shaft 2;

After the hexagon socket screw is tightened, install the U-joint 13, align the hydraulic pin 10 with the positioning hole 9, fill the hydraulic oil into the hydraulic sleeve 11 through the one-way valve 14, and push the hydraulic pin 10 out. Use the hydraulic structure, i.e., the hydraulic sleeve 11 and the hydraulic pin 10 structure, to tighten them again from both sides of the joint plate 6 and the flange joint 4.
