Pulley made of resin

Abstract

PURPOSE: To specify the state of contact of a belt with a pulley made of resin and to stabilize engagement therebetween by forming the top part of a microwaveform belt part located on the outer peripheral surface of an outside diameter cylinder part in succession to the outer peripheral surface of the outside diameter cylinder part. CONSTITUTION: Outside and inside diameter cylinder parts 2 and 3 are provided, the outside and inside diameter cylinder parts 2 and 3 are intercoupled through a disc part 4. Especially, the outside diameter cylinder part 2 has a plurality of microwaveform parts A and B formed on its outer peripheral surface 2a, and the microwaveform belt parts A and B are formed throughout the whole periphery of the outside diameter cylinder part 2. The microwaveform parts are formed in parallel in an axial direction, and top parts 10 are peripherally continued to each other. Namely, the top parts 10 of the microwaveform belt parts A and B formed on the outer peripheral surface 2a of the outside diameter cylinder part 2 form a contact point during engagement between belts, and the adjoining top parts 10 are peripherally continued to each other. This constitution specifies the state of contact of the belt with a pulley 1 made of resin and stabilizes engagement therebetween. COPYRIGHT: (C)1992,JPO&Japio
