Harmonic reducer, small size, large power
Release time:
2021-11-12
A harmonic drive is a type of gear reducer that uses a wave generator, a rigid wheel fixed in place, and a flexible wheel for output. The wave generator is a rod-shaped component with rolling bearings at both ends, pressing against the inner wall of the flexible wheel. The flexible wheel is a thick-walled gear that can undergo significant elastic deformation.
A harmonic reducer uses a wave generator, a rigid wheel fixed, and a flexible wheel output. The wave generator is a rod-shaped component with rolling bearings at both ends forming rollers, which are pressed against the inner wall of the flexible wheel. The flexible wheel is a flexible-walled gear that can produce a large elastic deformation.
Harmonic reducers have a high reduction ratio; a single coaxial stage can achieve a relatively high speed ratio. Unlike ordinary gear meshing, the backlash is small, which is an indispensable element for the controller field.
High precision
Multiple teeth mesh simultaneously, with two symmetrical gears meshing. Therefore, the influence of gear pitch error and cumulative pitch error on rotational accuracy is relatively average, making the positional accuracy and rotational accuracy reach a very high level.
Compared with previous gear devices, the volume is 1/3 and the weight is 1/2, while achieving the same torque capacity and reducer, realizing miniaturization and lightweight.
The flexible wheel material uses special steel with high fatigue strength. Unlike ordinary transmission devices, the number of simultaneously engaged teeth accounts for 30% of the total number of teeth, and it is surface contact, so the pressure on each gear is reduced, and a high torque capacity can be obtained.
The sliding at the tooth meshing part is small, reducing the power loss caused by friction. Therefore, while obtaining a high reduction ratio, high efficiency is maintained, and the drive is miniaturized.
The harmonic reducer's transmission movement force is balanced, the operation is relatively quiet, and the vibration is small.
Harmonic reducers are widely used in electronics, aerospace, robotics, and other industries. Due to their unique advantages, their application in the chemical industry is also gradually increasing.
