の潤滑機構。 An oil pump is connected to an oil supply pipe facing a predetermined portion of the power transmission device, and the driving of the oil pump supplies lubricating oil to the sliding portions of the power transmission device.
In the lubrication mechanism of a power transmission device that supplies lubricated parts such as shaft supports and meshing parts, lubrication is required only when the drive part of the power transmission device is driven at a high speed higher than a specified level, or to parts that cause lubrication failure. A branch pipe facing the oil supply pipe is provided in the oil supply pipe, and a flow control valve is provided which operates when the drive of the drive unit reaches a predetermined high speed to connect the branch pipe to the oil pump. A lubrication mechanism for power transmission devices.
