Embodiment Construction

[0030] The present invention will be further described in detail with reference to the accompanying drawings and embodiments.

[0031] Such as Figure 1 ~ Figure 3 As shown, the present invention provides an ultra-small harmonic reducer with an integrated design of bearings and harmonics, including a steel wheel a1, a steel wheel b2, a flexible wheel 3, a cam 4, a flexible bearing 5, a roller 6, and a roller Block 7, bearing retaining ring 8 and mounting screw 9. In addition, the harmonic reducer of the present invention also includes a sealing ring a10, a sealing ring b11 and a sealing ring c12.

[0032] The steel wheel a1 and the roller block 7 are connected together by mounting screws 9 to form an input steel wheel or an output steel wheel, and correspondingly, the steel wheel b2 is used as an output steel wheel or an input steel wheel. The inner ring of the steel wheel a1 has two parts with a larger diameter and a smaller one. A V-shaped ring groove is processed on the i...

Abstract

The invention discloses a subminiature harmonic reducer with integration of a bearing and harmonic wave. The subminiature harmonic reducer comprises a steel wheel a, a steel wheel b, a flexible wheel,a cam, a flexible bearing, a roller, a roller baffle block, a bearing retainer, a mounting screw and the like, wherein the steel wheel a and the roller baffle block are connected with each other to from an input steel wheel or an output steel wheel, and the steel wheel b serves as an output steel wheel or an input steel wheel; a V-shaped circular groove arranged at the inner diameter of the steelwheel a and a V-shaped circular groove arranged at the outer wall of the steel wheel b are cooperative with each other to form a rectangular circular groove, the steel wheel a is further provided with a fan-shaped groove, the roller is arranged in the rectangular circular groove through the fan-shaped groove, the steel wheel a serves as a bearing outer ring, the steel wheel b serves as a bearinginner ring, and the steel wheel a, the steel wheel b and the roller are combined together to form an integrated structure of the bearing and steel wheels. The subminiature harmonic reducer with integration of the bearing and harmonic wave has the advantages that the design reduces the number of structure components, the structure thickness is reduced, the weight of the bearing wall is reduced, thesize is smaller, and the installation performance and operability are improved.

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 ...
