FIELD: machine building.
SUBSTANCE: drive transfers rotational force from electric motor to spindle of vertically-drilling machine with variable speed through belts on stepped pulleys. In the example there are three stepped pulleys connected by two belts. Belt tensioning roller rests against one of the belts and can be adjusted along the arc-shaped slot in the fastening plate and fixed in a certain position by means of the adjusting head on the belt tensioning roller. Middle pulley is arranged to change its position so that adjustment of tension on one belt by means of belt tensioning roller also leads to adjustment of tension on second belt.
EFFECT: efficient adjustment of belt tension and transmitted power.
