Description

Sector gear convenient to adjust

Technical Field

The utility model relates to a gear technical field specifically is a sector gear convenient to adjust.

Background

A sector gear is a type of gear often used in industrial production, which is known as an incomplete disk-type gear because of its shape similar to a fan. The transmission mechanism is commonly used for transmission in a precise structure, improves the tightness degree of the whole transmission structure, optimizes the whole structure and reduces the volume of the structure. In the actual installation process, the connection of the sector gear and other gears not only needs to be tightly meshed, but also ensures flexible transmission. There is a proper clearance between the teeth to store the lubricant while coping with thermal expansion and contraction. However, long-term wear between gears necessarily results in loose gear engagement, requiring the user to maintain or replace the gears in a timely manner.

At present, the problem that gears are too loose or too tight in meshing is solved by adjusting the distance between the mounting holes of the sector gear and the adjacent gear, but due to the fact that the positions of other gears are fixed in a specific structure and cannot be adjusted, the gears can only be directly replaced at the moment, and normal operation of equipment is guaranteed. However, this method is costly and causes a large waste of resources.
