Using the dynamics mode,l w e study the ro- tational transm ission error of the decelerator, wh ich is caused by clearances of bearings, meshing clearances be- wt een cycloid gears and pin gears and rotational torque. The study results show that the clearances of bearings at crank shaft holes in both cycloid gears and carriers and their rotational torque have rather big effect on the transm i-s sion accu racy of the de
