摘要

The gear (1) has a gear case (2) partially filled with gear-oil for lubrication and cooling of the gear. An elongated body (5) is arranged within the gear case such that the body is immersed in the oil and expands itself when the gear is heated or warmed. The expansion of the body influences the gear oil level gauge, where the body is modularly built from several extension units.
