Rear force drawing structure of engine. The rear force taking structure of the engine comprises a flywheel shell, one end of which is provided with an automatic self-aligning ball bearing bearing hole on the inside, and the other end is provided with a rear end force taking mouth; The bearing cover is fixed on the force mouth at the rear end of the flywheel housing to form a PTO shaft layout space; The bearing cover is axially provided with a cylindrical roller bearing bearing hole; The far output end of the PTO shaft is supported by automatic self-aligning ball bearing, and the near output end is supported by cylindrical roller bearing, which is arranged in the layout space of the PTO shaft to form a bilateral support structure of the PTO shaft. Force after the engine structure simple and reasonable structure, by far in the bearing support output using automatic self-aligning ball bearings, nearly output using general cylindrical roller bearing, axis of automatic self-aligning ball bearing automatic adjustment, reduce the alignment requirements of bearing hole processing technology is simple, low manufacturing cost, large quantities of high production efficiency, convenient lubrication, can prevent the bearings burned to death.
