PORTIONER OF PLASTIC LUBRICANT Russian patent published in 2000 - IPC

FIELD: devices metering plastic lubricant predominantly for single-time injection in large amount fed into large-sized friction units. SUBSTANCE: portioner of plastic lubricant has lubricant reservoir, rotary pump, four-line two-position weighing machine, connection and feeding pipe-lines and electric control system. Weighing machine comes in the form of sealed cylinder that houses piston. Guiding bushings where mobile rods are placed are built in lids of cylinder in parallel to its axis. Thrust washers interacting with face surfaces of piston are put on internal ends of rods located in cylinder. Springs put on rods are installed between thrust washers and lids of cylinder. Electric control system has two limit switches interacting with external ends of mobile rods of cylinder. EFFECT: increased operational reliability, provision for single-time filling of large-sized friction units with needed amount of plastic lubricant, prolonged service life of friction units, reduced usage of lubricant and improved environmental ecology. 1 dwg
