Problems solved by technology

[0006] Although the harmonic reducer drive has the above obvious advantages, it is affected by the manufacturing accuracy of the harmonic reducer gear and the accuracy of the gear after wear, refer to image 3 , the gap between the flexible gear 2 and the rigid gear 1 is large, the existence of this gap will affect the transmission accuracy and transmission stability of the harmonic reducer, and also affect the service life of the harmonic reducer
At present, the domestically produced harmonic reducer is still difficult to meet the needs of high-precision transmission, such as the harmonic reducer required on the robot

Embodiment 2

[0040] refer to Figure 13 The only difference between this embodiment and Embodiment 1 is that there are two elastic compensating devices 5, which are respectively located on the outer peripheral edges of the opposite ends of the cam body in the direction of the long axis. All the other are with embodiment 1.

Embodiment 3

[0042] The difference between this embodiment and Embodiment 1 is that the number of elastic compensating devices 5 is 6, and there are 3 outer peripheral edges at opposite ends of the cam body in the long axis direction. All the other are with embodiment 1.

Embodiment 4

[0044] refer to Figure 14 , the difference between this embodiment and Embodiment 1 is that this embodiment is a harmonic reducer for single-wave transmission, the number of elastic compensating device 5 is one, and the elastic compensating device 5 is located at the outer peripheral edge of the long axis end of the cam body . All the other are with embodiment 1.

Abstract

The invention provides a harmonic reducer with a function of eliminating or decreasing clearance between gears through automatic compensation. The harmonic reducer comprises a rigid gear, wherein a flexible gear is arranged in the rigid gear; a flexible bearing is arranged in the flexible gear; a cam is arranged in the flexible bearing; the cam and the flexible bearing jointly form a wave generator; a central hole is formed in the cam; and the cam comprises a cam body and elastic compensation devices which are arranged on the edge of the external circumference of the cam body. The harmonic reducer with the function of eliminating or decreasing clearance between the gears through automatic compensation is high in transmission accuracy, good in transmission stability and long in service life.

Description

technical field [0001] The invention relates to a harmonic reducer, in particular to a harmonic reducer with the function of automatic compensation, elimination or reduction of gaps between gears. Background technique [0002] Harmonic reducer, also known as harmonic reducer or harmonic transmission reducer, is a new type of reducer developed based on the principle of planetary gear. refer to figure 1 , 2 , the harmonic reducer is mainly composed of three basic components: a wave generator, a flexible gear 2, and a rigid gear 1. The wave generator is composed of a cam 3 and a flexible bearing 4. The flexible gear 2 is controlled to elastically deform through the wave generator. And mesh with the rigid gear 1 to transmit the gear transmission of motion and power. refer to Figure 4 , 5 , 6, the cam 3 is a cylindrical structure with a central hole. [0003] The main advantages of harmonic drives are as follows: [0004] Large transmission ratio: the single-stage harmoni...
