Design of a roller bearing grease removal device

Abstract

In the present Scenario, The manual method for Removing grease from the Roller Bearing used in the railway department became a major problem. Chemicals will effect humans while cleaning the railway bearings in manual method. In order to reduce human effect and increase efficiency in cleaning, we are aimed to design a machine which will automatically clean the bearings and will decrease the time of cleaning. In the overhauling process, which will be done manually will be directly apply the kerosene and the compressed air. This suggested machine will clean the bearing automatically by providing kerosene and compressed air with high velocity. The compressed air with high velocity will be provided to rotate the bearing continuously and kerosene will be applied simultaneously, Thus the cleaning of the bearing. Will be done automatically. It works on principle that kerosene air mixture will reduce the density and remove the grease from the bearing completely and it is collected in a drain. After the overhauling process, the parts will be assembled in the railway coaches. So this machine can reduce the time in the working process and avoids the human problems in manual method.
