Problems solved by technology

[0002] Due to the errors in gear processing and installation, there are often gaps between the meshing teeth of the current gear transmission with a fixed center distance, which causes transmission delays between the driving gear and the driven gear, and shaking of the transmission structure. This is a problem in precision equipment. must be eliminated

Embodiment 1

[0021] Such as figure 1 As shown, a backlash elimination mechanism for a gear transmission with a fixed center distance is located between the gear transmissions to be adjusted. The backlash elimination mechanism is provided with a forward backlash elimination component F, a reverse backlash The elimination component E and an adjustment pin 7, the forward backlash elimination component fits with the reverse backlash elimination component and is fixed by the adjustment pin, only need to turn the adjustment pin to adjust the forward backlash elimination component and the reverse backlash elimination component The relative angle can realize the backlash elimination of the gear transmission with fixed center distance.

[0022] Such as Figure 6 As shown, the adjustment pin 7 is structured as an eccentric shaft, installed in the gear 3 and the gear 4, and can adjust the angle of the gear 3 relative to the gear 4.

[0023] The forward backlash elimination mechanism F is provided w...

Embodiment 2

[0030] The upper gear can also be used to eliminate the backlash of the gear transmission, and the adjustment pin can also be installed on the driving gear 5 and the driving gear 6.

Abstract

The invention relates to a tooth gap elimination mechanism for a center distance fixing gear drive and an elimination method thereof. The gear-driven tooth gap elimination mechanism is characterized by being arranged between to-be-regulated gear drives, the gear tooth gap elimination mechanism is provided with a group of forward tooth gap elimination assemblies, a group of reverse tooth gap elimination assemblies and a regulating pin, and the forward tooth gap elimination assemblies and the reverse tooth gap elimination assemblies are fixed together through the regulating pin; and only the regulating pin is rotated, a relative angle of the forward tooth gap elimination assemblies and the reverse tooth gap elimination assemblies is regulated, and tooth gap elimination of the center distancefixing gear drive can be achieved. The tooth gap elimination mechanism for the center distance fixing gear drive and the elimination method thereof have the beneficial effect that the tooth gap can be eliminated without changing of the gear center distance.

Description

technical field [0001] The invention relates to the field of gear transmission, in particular to a gear transmission with a fixed center distance, which can eliminate backlash. Background technique [0002] Due to the errors in gear processing and installation, there are often gaps between the meshing teeth of the current gear transmission with a fixed center distance, which causes transmission delays between the driving gear and the driven gear, and shaking of the transmission structure. This is a problem in precision equipment. must be eliminated. Contents of the invention [0003] The purpose of the present invention is to solve the need to eliminate the gap between the meshing teeth of the gear transmission with fixed center distance in the prior art, and provide a gear gap elimination mechanism with novel structure, safety and reliability, and simple operation. [0004] To achieve the above object, the present invention is achieved through the following technical sol...
