Title: Gear apparatus
Inventor: ONO KOSAKU
IPC: F16H57/029
Filed: 1998-05-27
Abstract: PROBLEM TO BE SOLVED: To directly measure a temperature of a lubricating oil discharged from a mesh part and defect a sign of a seizure in a tooth blank by arranging a temperature measurement means at the side opposite to where a pair of gears mesh with each other. SOLUTION: A small gear 1 and a large gear 2 mesh with each other thereby forming a gear pair. A lubricating oil is supplied from a feed nozzle 3 to the side where the gear pair meshes, and discharged to the opposite side by a pump action of the gears 1, 2. A temperature measurement means 4 is arranged in the vicinity of the opposite side to where the gear pair meshes, and directly measures a temperature of the lubricating oil discharged from a mesh part. The measurement result is displayed at a temperature display device 5 set outside a gear box. The temperature of the lubricating oil immediately after discharged from the mesh part of the gear pair is close to a temperature of a thread face. Therefore, a seizure of the tooth blank can be detected early by directly measuring the temperature.  A gear apparatus of a high reliability with the inexpensive temperature monitor device is obtained accordingly.
