Claims

[Scope of utility model registration request]

A reservoir tank capable of receiving and storing lubricating oil filled in the case of the gear transmission to such an extent that a part of the gear is immersed, and an oil drain pipe that communicates the case and the reservoir tank are interposed. 1st
and a second oil supply pipe that communicates the reservoir tank with a nozzle that injects lubricating oil to a bearing that supports a gear of the gear transmission and a gear shaft to which the gear is fixed. In response to detection signals from the electromagnetic valve and hydraulic pump, an oil level sensor that detects the oil level in the case, a temperature sensor that detects the temperature of the bearing, and a rotation sensor that detects the rotational speed of the gear shaft, the 1. A lubrication device for a gear transmission, comprising a control device for controlling first and second solenoid valves and a hydraulic pump.
