| description | A tool structure for surface durability testing of a powder metallurgy supporting disc for an automobile gearbox comprises a high-pressure end shell, a low-pressure end shell, a piston, an oil guide seat, a bearing seat assembly and a transmission shaft, the high-pressure end shell and the low-pressure end shell are oppositely combined, and the piston is installed in a cavity in one side of the high-pressure end shell and abuts against the inner wall of the high-pressure end shell through a spring. The oil seat is installed on a center seat on the inner side of the low-pressure end shell, the bearing seat is installed outside the oil guide seat, the powder metallurgy supporting disc is installed in the piston and the low-pressure end shell, the transmission shaft penetrates through the high-pressure end shell to be connected with the bearing seat, a high-pressure oil hole is formed in the high-pressure end shell, and a high-pressure oil cavity is formed between the piston and the high-pressure end shell.
