Pulley belt installer for a belt-type stepless transmission

Abstract

A pulley belt installer has a pulley holder (6) for holding one pulley (2) of a pair of pulleys, a held pulley width expander (5) for expanding the groove width of the pulley held by the pulley holder, a pulley belt holder (8) for holding a pulley belt in the condition in which part of the pulley belt (PB) is located in the groove of the pulley held by the pulley holder, and a pulley rotator (16) for rotating the other pulley (1) at least 90 degrees in the condition in which another part of the held pulley belt is located in the groove of the other pulley, so that the center axes of both pulleys about a rotation axis intersecting with the center axis of the other pulley are parallel, thereby assembly the pulley belt without causing overlap between the surfaces of the two V-grooves of the pair of pulleys.
