Wear resistance testing machine for powder sleeve

The invention belongs to the field of testing machines, and relates to a wear resistance testing machine for a powder sleeve. The testing machine consists of a workbench assembly, a rotary reciprocating conversion mechanism, a linear bearing long frame assembly, a to-be-loaded support assembly, a reciprocating rotating shaft assembly, a rotary bearing assembly, a damping device assembly, a driving rotary motor assembly, a powder sleeve driving disc assembly, a linear bearing short frame assembly, a driving rotary motor assembly, a circuit wire arrangement diagram, a driving reciprocating lever motor assembly, a dual-purpose end panel hand assembly, a single-phase electricity-to-three-phase electricity variable-frequency speed regulation device and a welding type workbench supporting frame. The machine mainly aims at the wear resistance of the powder sleeve of a motorcycle driving wheel; by simulating the operation conditions, the powder sleeve is installed in a driving disc in an adapter ring to perform 24-ho
