Screw Gear ReducerThe transmission unit employs a two-stage helical gear mechanism with bidirectional action. The gears of the worm gear reducer have a medium-hardness tooth surface. After the vibrating oscillation ceased, we opened the cover for inspection. So, what are the steps for an internal inspection of the worm gear reducer? Here's a detailed explanation:

The clearance of the south and north bearings on shaft I is 0.15mm and 0.10mm, respectively. The clearance of the south and north bearings on shaft II is 0.22mm and 0.20mm, respectively. The clearance of the south and north bearings on shaft III is 0.15mm and 0.20mm, respectively.

The gap between the lateral shims is 0.64mm and 0.40mm respectively, and the output shaft height from the mating surfaces of the top and bottom shells to the lowest point of the output shaft can be 224.98mm.

3. There is slight pitting on the working tooth surface of the high-speed shaft's small gear and the large gear that meshes with it.

The above provides an introduction to the internal inspection steps of worm gear reducers. The internal inspection reveals a pair of gears, two-stage meshing. The gear teeth surfaces are severely rusted. The teeth of the small gear and the worm gear are corroded and flaked off. Due to pitting and flaking, a small groove has formed nearby. It measures approximately 1-1.5mm deep and is about 80% the length of the gear teeth. The involute tooth shape of the worm gear reducer's gear teeth section has been altered.
