Description

Technical Field

[0001] This utility model relates to the field of gear assembly technology, and more specifically, to a quick-installation precision small-module gear assembly. Background Technology

[0002] Small module gears refer to gears with a module of less than 2mm. Due to their advantages such as small size, smooth transmission, and high load-bearing capacity, they have been widely used in aerospace, medical devices, precision instruments, automobiles, electronic products, home furnishings, 3C electronics, robots, industrial equipment, and communications. With the advancement of technology and the development of industry, small module gears are showing a continuous upgrading trend in terms of precision, performance, and application areas.

[0003] When installing and assembling small module gears, they are typically installed inside corresponding housings to form gear sets. However, most gear sets have enclosed housings with only one end open to the outside. Assembly requires fitting the gear onto the housing through this open end and then using tools to secure it. This process is relatively cumbersome and doesn't allow for disassembling the housing to expose more parts before assembly, hindering the achievement of quick-assembly. Therefore, we propose a quick-assembly precision small module gear set. Utility Model Content
