Problems solved by technology

However, the rigid wheel is an internal gear, and it is difficult to align the extreme positions of the two measuring rods during measurement. Therefore, not only the measurement accuracy is not high, but also the operation is inconvenient and the measurement efficiency is low.
Therefore, the existing rigid wheel detection method is still not ideal enough and needs to be further improved.

Embodiment Construction

[0018] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0019] A method for detection of backlash-free meshing of harmonic gears and rigid wheels of the present invention, such as Figure 1~4 As shown, the method includes using a two-claw or three-claw inner diameter micrometer 1 to detect the internal teeth 3.1 of the rigid wheel 3 of the harmonic gear, that is, using a two-claw or three-claw inner diameter micrometer 1 to detect the inner teeth 3.1 of the rigid wheel 3 of the harmonic gear. When testing the internal teeth 3.1, a fan-shaped measuring block 2 is arranged on each measuring head 1.1 of the two-claw or three-claw inner diameter micrometer 1, and each measuring block is provided with an internal tooth 3.1 capable of connecting with the rigid wheel 3. The meshing gear teeth 2.1 make the gear teeth 2.1 of the measuring block 2 on each measuring head 1.1 of the two-jaw or three-jaw inner ...

Abstract

The invention discloses a method and a device for detecting backlash-free meshing of a rigid gear of a harmonic gear. The method comprises the following steps of: detecting rigid gear internal teeth of the harmonic gear by adopting a two-claw or three-claw inside micrometer; and when the rigid gear internal teeth of the harmonic gear are detected by adopting the two-claw or three-claw inside micrometer, configuring a fan-shaped measuring block on each measuring head of the two-claw or three-claw inside micrometer, and arranging gear teeth which can be meshed with the rigid gear internal teethon each measuring block to ensure that the gear teeth of the measuring block on each measuring head of the two-claw or three-claw inside micrometer are tightly attached to the rigid gear internal teeth without backlash, so that the tooth thickness control size of the rigid gear internal teeth can be detected through the two-claw or three-claw inside micrometer. By adopting the method and the device, the measurement operation is very convenient, the efficiency of measurement work can be greatly improved, the measurement accuracy is completely determined by the accuracy of the inside micrometer,and the influence of human factors on the measurement accuracy is greatly reduced.

Description

technical field [0001] The invention relates to a method and device for detection of backlash-free meshing of harmonic gears and rigid wheels, belonging to the technical field of mechanical transmission detection. Background technique [0002] Harmonic drive is mainly composed of rigid wheel, flexible wheel and wave generator. The inner circle of the rigid spline is provided with internal teeth, and the outer circle of the flexible spline is provided with external teeth. The flexible spline is set on the oval wave generator, and the flexible spline undergoes controllable deformation under the action of the wave generator, so that The outer teeth of the flexible spline near the axis are completely meshed with the inner teeth of the rigid spline; the outer teeth of the flexible spline near the short axis of the wave generator are completely disengaged from the inner teeth of the rigid spline; the outer teeth of the flexible spline between the major axis and the short axis Gra...
