Embodiment Construction
[0026] The present invention will be further described in detail with reference to the accompanying drawings and embodiments.
[0027] Such as Figure 1 ~ Figure 3 As shown, the present invention provides an ultra-small harmonic speed reducer with integrated bearing and harmonic design, including steel wheel a1, steel wheel b2, steel wheel c3, flexible wheel 4, cam 5, flexible bearing 6, roller 7. Bearing retaining ring 8 and mounting screw 9.
[0028] The steel wheel a1 and the steel wheel b2 are connected together by mounting screws 9 to form the input steel wheel or the output steel wheel of the present invention, and correspondingly, the steel wheel c3 is the output steel wheel or the input steel wheel. The internal teeth of the steel wheel a1 and steel wheel c3 mesh with the external teeth of the flexspline 4, and the power is input through the cam 5, which drives the flexible bearing 6 to rotate and deform, the flexspline 4 and the flexible bearing 6 deform accordingly,...

The invention discloses a bearing and harmonic wave integrated subminiature harmonic reducer. The bearing and harmonic wave integrated subminiature harmonic reducer comprises a steel wheel a, a steelwheel b, a steel wheel c, a flexible wheel, a cam, a flexible bearing, a roller, a bearing retainer ring and a mounting screw, wherein the steel wheel a and the steel wheel b are connected so as to form input steel wheels or output steel wheels, and the steel wheel c is used as an output steel wheel or an input steel wheel; a 45-degree chamfer is processed on the inner wall of the steel wheel a, the 45-degree chamfer and another 45-degree chamfer which is processed on the inner wall of the steel wheel b form a V-shaped circular groove, then the V-shaped circular groove is matched with anotherV-shaped circular groove which is processed in the outer wall of the steel wheel c so as to form a square circular groove, and the roller is installed in the square circular groove; the steel wheel aand the steel wheel b are used as bearing outer rings, and the steel wheel c is used as a bearing inner ring so as to form a bearing and steel wheel integrated structure together with the roller; andthe flexible wheel, the flexible bearing and the cam sleeve with each other in sequence. The design of the bearing and harmonic wave integrated subminiature harmonic reducer has the advantages of light weight of harmonic wave and simple structure, the diameter and thickness of harmonic wave under same parameters are effectively reduced, and the usability is increased.
Description
technical field [0001] The invention relates to a harmonic reducer, in particular to an ultra-small harmonic reducer integrating bearings and harmonics. Background technique [0002] Harmonic reducers have the characteristics of high transmission efficiency, small size, light weight, stable transmission, and low noise. They are widely used in the field of robots, especially in collaborative robotic arms and service robots. With the development of robotics, the size requirements for harmonics are becoming more and more stringent. [0003] The traditional harmonic reducer is divided into three parts: wave generator, flex spline and steel wheel. In order to meet the requirements of harmonics on axial force, radial force and bending moment, cross roller bearings are often used to connect flex splines. and steel wheels. [0004] For example, the green harmonic LCD series adopts the form of a cup-shaped flexspline, connects the output part of the flexspline to the outer ring of ...
