求翻译：光轮回转装置布置在牵引链回空线的转弯处且用在回转角度比较大而回转半径较小的场合，其作用同样是为了给牵引链条在回转处提供平滑过渡。是什么意思？

Light cycle of the transfer device is arranged in the corner of the traction chain back to the empty line and used in the turning angle of the smaller radius of gyration occasions, its role also is to provide a smooth transition to the traction chain in the rotation at.

The unit circle in the chain back to the line of the turn, and compare with the swivel angle of the swing radius is small, its role is also in order to tow chain to swing in the smooth transition.

The corona turning gear arrangement is towing the chain to return to the disengaged line the turning also to use in the rotation angle quite is big the radius of gyration small situation, its function is similarly in order to give tows the chain link to provide the smooth transition in the rotation

Light traction chain wheel rotating device placed in the bend of the huikong line and in relatively large rotary angle and radius of gyration smaller occasions, to traction chain whose role is to provide a smooth transition at the Rotary.
