Abstract
An oil baffle removal device comprises a pressure plate and a pressure disc. The pressure plate is provided with a protective disc, a first fastening part and a second fastening part, wherein the first and second fastening parts are connected to the protective disc. The pressure plate is fixed around an oil baffle through the first and second fastening parts. The pressure disc faces to the oil baffle, and the pressure disc is slidably connected with the protective disc. A buffer device is disposed between the pressure disc and the protective disc and provides the pressure disc with buffering force when the oil baffle pops out. The oil baffle removal device has the advantages that when the oil baffle in a transmission is removed, popping motion of the oil baffle can be limited in a certain range under the barrier action of the pressure disc and buffering action of the buffer device, popping energy of the oil baffle can be reduced to zero, and the oil baffle is prevented from popping out and moving at random to injure operators with over-high energy.
