Title: Lubricator for oil film bearing
Inventor: OOMORI SHIYUNJI
IPC: F16N39/02
Filed: 1979-04-13
Abstract: PURPOSE: To utilize the pumping action of a bearing for a rolling machine to reduce the quantity of supplied oil, by opening an oil outlet port in front of the load carrying surface of a bearing member and an oil inlet port at the rear of the load carrying surface and providing pipes to connect the ports to a cooler.  
     CONSTITUTION: An oil outlet port 1 is opened in front of the load carrying surface of a bearing. An oil inlet port 3 is opened at the rear of the load carrying surface. The ports are connected to a cooler 2 through pipes 4a, 4b. When a shaft rotates, pressure changes and oil increases and the bearing performs pumping action. Oil discharged by the pumping action flows out of the outlet port 1 and is cooled by the cooler 2 so that the oil is supplied again to the bearing through the oil inlet part 3. The quantity of cooling water of the cooler 2 is regulated by a discharged oil temperature measuring sensor 10, an oil temperature controller 9 and a control valve 5. This results in making a pump compact, suppressing the rise in the temperature of the bearing and preventing seizure.
