Problems solved by technology

[0003] However, the existing harmonic drive reduction devices are all single-layer structures, which are difficult to achieve for higher speed changes.
At the same time, the harmonic rate is not high, and the output of super torque cannot be realized
Moreover, due to the demand for structural precision, the structure of the entire device will be too large and the distribution will not be compact enough

Embodiment Construction

[0015] Such as figure 1 The mosaic type double-layer harmonic drive reduction device shown includes a wave generator. The output end of the wave generator is provided with an input shaft 1, and a cam 2 is installed outside the input shaft 1. It is unique The reason is that the cam 2 used in the present invention is distributed with an inner layer of flexible bearings 3 . Specifically, the inner layer flexible bearing 3 is covered with an inner layer flexible wheel 4 . Looking further, the inner flexible wheel 4 is overcoated with an inner steel wheel 5 , and the inner steel wheel 5 is overcoated with an outer flexible bearing 6 . At the same time, the outer layer flexible bearing 6 is covered with an outer layer flexible wheel 7 , and the outer layer flexible wheel 7 is covered with an outer layer steel wheel 8 .

[0016] As far as a preferred embodiment of the present invention is concerned, the outer circle of the inner steel wheel 5 used is elliptical.

Abstract

The invention relates to an embedded two-layer harmonic drive reducing gear, which comprises a wave generator. The output end of the wave generator is provided with an input shaft, and a cam is arranged outside the input shaft. The embedded two-layer harmonic drive reducing gear is characterized in that inner-layer flexible bearings are distributed outside the cam; and an inner-layer flexible wheel is sleeved outside the inner-layer flexible bearings. Furthermore, an inner-layer steel wheel is sleeved outside the inner-layer flexible wheel, and outer-layer flexible bearings are sleeved outside the inner-layer steel wheel. Meanwhile, an outer-layer flexible wheel is sleeved outside the outer-layer flexible bearings, and an outer-layer steel wheel is sleeved outside the outer-layer flexible wheel. Therefore, double-layer harmonic waves are realized, and can achieve a higher gear ratio than the conventional single-layer harmonic waves. Meanwhile, due to the elliptical fit design, the accuracy and the efficiency are higher than single harmonic waves. The huge torque output can be realized; and in addition, the embedded two-layer harmonic drive reducing gear is precise in structure, small in size and compact in structure, easily adopts to different installation places and deserves promotion and application.

Description

technical field [0001] The invention relates to a deceleration device, in particular to a mosaic double-layer harmonic drive deceleration device. Background technique [0002] Harmonic drive reducer is a mechanical transmission device that uses the controllable elastic deformation of flexible elements to transmit motion and power. Because the harmonic transmission reducer has many advantages, it has been widely used in energy, electronics industry, petrochemical industry, military industry, robot, machine tool, instrumentation, medical equipment and other fields. [0003] However, the existing harmonic drive deceleration devices all have a single-layer structure, which is difficult to achieve a higher speed change. At the same time, the harmonic rate is not high, and the output of super torque cannot be realized. Moreover, due to the requirement of structural precision, the structure of the entire device is too large and the distribution is not compact enough. Contents o...
