AI Technical Summary

Technical Problem

The existing double-gear structure requires high machining accuracy and is inconvenient to adjust. After wear, the clearance increases, requiring regular manual adjustment, which affects the accuracy and maintenance efficiency of the rotary table.

Method used

A flexible and adjustable double-gear backlash-eliminating transmission structure is designed. It adopts a three-section transmission structure and achieves automatic gear engagement by adjusting the shaft and spring ball to eliminate backlash. It can be easily adjusted outside the housing, avoiding the need to disassemble the worktable.

Benefits of technology

It achieves stable precision of the rotary table even after wear, making maintenance convenient and quick, reducing the need for regular adjustments, and improving the service life and production efficiency of the equipment.

Abstract

The invention discloses a flexible adjustable double-gear anti-backlash transmission structure, and relates to the technical field of rotary workbenches, the flexible adjustable double-gear anti-backlash transmission structure comprises a shell, a driving motor is fixedly mounted on the inner side of the shell, a workbench is rotatably connected to the inner side of the shell, a gear disc is arranged at the shaft part of the workbench, and the gear disc is rotatably connected to the inner side of the shell. The outer side of the tooth portion of the gear disc is connected with a felt gear in a meshed mode, an adjusting arm is arranged on the inner side of the shell and rotationally connected with the shell through a rotating shaft, an intermediate gear shaft is rotationally connected to the inner side of the adjusting arm, and a second gear is fixedly installed at one end of the shaft portion of the intermediate gear shaft. When a corresponding gear is abraded, stable pressing can still be achieved; the adjusting piece is designed outside the shell and can still be conveniently adjusted in a limited space; the scheme is convenient to maintain, the gear backlash is not required to be adjusted after the whole worktable is detached from a machine tool, the worktable can be directly operated in the machine tool, the maintenance is convenient and fast, and the maintenance period is effectively prolonged by the spring structure.
