Test bed for measuring friction force of reciprocating framework oil seal

A test bed for measuring friction force of a reciprocating type framework oil seal is mainly composed of a base, a protective cover, a rear baffle, a linear motor, a transmission device, an oil seal assembling device, an oil conveying pipe and a hydraulic device. The protective cover and the rear baffle are fixed to the base, the linear motor and the oil tank are installed on the rear baffle, thecantilever beam is connected with the linear motor through bolts, the tension and pressure sensor, the U-shaped connector, the universal shaft head and the piston rod are sequentially installed belowthe cantilever beam, and the piston rod penetrates through the oil tank and an end cover of the oil tank, is placed into the oil seal tray and the oil seal and is fixed through the pressing piece. Thefriction force between the oil seal and the piston rod can be measured by simulating the actual working condition, and the linear motor drives the piston rod to reciprocate; oil can be heated and pressurized through the heatin
