Abstract

The invention discloses an anti-backlash mechanism which comprises a mandrel component, a first gear and a second gear. The shaft sleeve component is arranged outside the core shaft component in a sleeving mode, a second gear is formed on the head portion of the shaft sleeve component, the first gear and the second gear are coaxial and arranged side by side front and back, and the first gear and the second gear are both used for being meshed with tooth components of external equipment at the same time; the shaft sleeve component is sleeved with the driven component, and the driven component and the shaft sleeve component coaxially rotate; the adjusting mechanism is arranged at the tail of the mandrel component and the tail of the shaft sleeve component, and the adjusting mechanism adjusts the dislocation amount between the outer teeth of the first gear and the outer teeth of the second gear by changing the relative rotation angle of the mandrel component and the shaft sleeve component.

Description

technical field [0001] The invention relates to the technical field of transmission, in particular to an anti-backlash mechanism for gear transmission. Background technique [0002] It is known that two gears can transmit rotary motion and power through meshing, such as figure 1 said, the figure 1 It shows the state when the gear meshes with the inner teeth of the ring gear. It can be seen from the figure that there is a meshing gap between the outer teeth of the gear and the inner teeth of the ring gear. Most of the meshing gaps are caused by machining errors and other principles. . Under lower transmission accuracy requirements, the meshing gap is allowed to exist, however, under higher transmission accuracy requirements, the meshing gap will cause the following problems: [0003] After one gear is braked, the other gear meshing with this gear can still produce a large amount of circumferential movement. [0004] In the prior art, the method of improving the machining ...
