Example Embodiment

[0012] The embodiments of the present invention are further described below in conjunction with the drawings.

[0013] Such as figure 1 As shown, the multiple-wave harmonic drive reducer of the present invention includes an input shaft 1, a fixed rigid wheel (ie, a housing) 2, a wave generator 3, a double flexible wheel 4, an output rigid wheel 5, and an end cover 6. Among them, the wave generator 3 and the input shaft 1 are firmly connected with keys and cylindrical pins, and the output steel wheel 5 is self-contained with the output part, and the torque is transmitted in the form of a shaft, and the speed is reduced. The motor drives the input shaft 1 to rotate at a high speed, and the input shaft 1 drives the wave generator 3 to rotate to produce controllable deformation of the flexspline 4. The external gear at one end of the flexspline 4 meshes with the internal gear of the fixed rigid wheel 2, resulting in staggered tooth motion. The first-order harmonic deceleration is rea...

Abstract

The invention provides a complex-wave type harmonic drive speed reducer, which comprises a wave generator, a flexible gear, a fixed rigid gear and an output rigid gear, wherein the wave generator is provided with cams, a first flexible bearing and a second flexible bearing; the flexible gear is provided with a first external gear and a second external gear which are respectively arranged at two ends of the flexible gear; a first external gear of the flexible gear is meshed with the fixed rigid gear through the cam via the first flexible bearing, and the second external gear of the flexible gear is meshed with the output rigid gear through the cam via the second flexible bearing. The complex-wave type harmonic drive speed reducer has the advantages of realization of two-stage harmonic-drive speed reduction in the form of complex waves, compact structure, small volume, large transmission ratio, high transmission precision and wide range of application.

Description

technical field [0001] The invention belongs to the field of mechanical transmission, and in particular relates to a harmonic drive reducer. Background technique [0002] In the prior art, the harmonic transmission reducer plays an important role in the subsystems of attitude adjustment and automatic control during the flight movement of the flight carrier. Due to its small size, light weight, and large output torque, it is The market demand is increasing year by year, and it is widely used in various fields of various industries, especially in some special fields, which require a large reduction ratio. [0003] The single-stage linear harmonic reducer widely used at present, due to the influence of the torque, the selected harmonic model (the model is usually distinguished by the inner diameter of the flexible spline), the gear module and the processing tool, the flexspline and rigid spline The module of the wheel should not be too small, that is, the reduction ratio of th...
