What Are The Assembly Steps Of The Miniature Reducer?

The gear transmission of the reducer refers to a set of devices that use the direct contact (mesh) between the gear teeth and the gear teeth between the main and slave gears to transmit power. One of the most important variables in determining the lifespan of a motor is the installation procedure. The following will introduce the assembly steps of the micro reducer.

1. Preparations

Clean up the anti-rust oil, dust, chips and other contaminants on the surface of all parts, and be familiar with the methods, drawings, and the connection between the various product parts (to prevent scratches and damage to the mating surface during use of the parts). Major matching measurements, including bore and journal, must be double-checked, and components can only be put together after certification.

2. Combine the gear shaft assembly.

When the shaft and gear are installed as a transition fit, some obstacles arise. If the interference level is not too high, tap and install with a hand tool such as a copper rod. Gears with large interference need to be assembled hydraulically or thermally; when the interference is large, a press can be used for pressing.

3. Installation of gear shaft bearing

When the constructed bearing is a special bearing, the size and allowance of the bore will affect the axial clearance. Bearing clearance can be modified as described below. The clearance between each bearing and the shoulder or spacer must be less than 0.02 inches. Before assembly, it is important to verify the width of the oil inlet groove and the size of the oil hole in the ball bearing and double row bearing rings.

4. Make the reducer body level.

The reducer box body should be leveled first, and the box body should be in a horizontal state, generally within 0.1mm, before the constructed gear shaft section can be hoisted on the box body.

5. The gear box body is equipped with gear shaft parts.
