Oil expansion tank with oil level control

Coaxial or angular gear units must be completely filled with oil when installed vertically.

 

During filling, an air bubble may form in the upper part at the level of the shaft seal, which must be eliminated to prevent insufficient lubrication. Since the oil volume increases as the temperature rises, an expansion tank with oil level control and breather filter must be installed to compensate and prevent harmful excess pressure inside the gear unit.

Shrink discs

Shrink discs are among the detachable shaft-hub connections. They are used in slip-on gearmotors. They are insensitive to dirt, have no moving parts and are therefore not subject to wear. Shrink discs offer the advantage of absolute freedom from backlash, especially in reversing operation.
