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.
