0.2M Turbine Worm Gear Micro 90° Transmission Box 12-Times Reduction Mechanism Gearbox DIY Car Model

Before purchasing the regular version, it is necessary to know:

The concentricity of the bearing needs to be adjusted well and needs to be run in (with a tight axis distance), which requires certain assembly capabilities.

Suggest purchasing Precision version, which is easy to assemble and has a slightly larger appearance.

• 1...This product requires high assembly skills and requires a certain level of hands-on ability, debugging ability, and basic operating tools

• 2...Both input and output shafts have a diameter of 1mm and a length of 30mm, achieving a reduction ratio of 12 times;

• The worm gear is tightly matched with the shaft. If there is no appropriate clamping tool such as a small vise, you can also expand the hole and fix it with glue by yourself. (Be careful not to press the shaft askew), it is best to cover the shaft with a 1m sleeve during crimping, or partially expand the hole on the worm gear.

• 3....The bearing of the worm gear and worm gear on the brass frame can be tightly matched. First, use small pliers and other tools to press one of them in, install the worm gear and worm gear, and then press the other one (one method is to use a small sleeve to cover the shaft, and then use the sleeve to press in the bearing).

• 4...During the pressing process of the two bearings of the turbine, it is important to keep the bearing holes on both sides as vertical as possible, otherwise they may get stuck. After pressing the bearings on one side, the shaft can be used to slightly pry the direction of the bearings for debugging.

• 5...After the complete set of crimping is completed, it may get stuck. You can use a hand drill to clamp the worm shaft and perform high-speed running in.
