Abstract

The invention relates to a method for the manufacture of a pulley arrangement (1) for tension rollers or transmission element rollers, said pulley arrangement (1) comprising a pulley (2), at least two rolling bearings (6, 10) and a bushing (14 ), the rolling bearings (6, 10) are adjacently installed on the shaft sleeve (14) by injection molding material on the rolling bearings (6, 10) to form the pulley (2).

Description

technical field [0001] The present invention relates to a method for the manufacture of a pulley arrangement for a tension roller or a roller designed to cooperate with a transmission element, such as a cam in an internal combustion engine of a motor vehicle belt or chain etc. The invention also relates to an engine equipped with the pulley device. Background technique [0002] Such rollers are often used to permanently maintain the tension of transmission components such as belts or chains within a given range, or to locally alter the path of said belts or chains. These are called tension rolls or rollers, respectively. [0003] In a roller, the pulley is rotatably mounted on a screw or shaft through a bearing, and the roller is then directly or indirectly connected to the engine block or tension roller device such as an articulated arm or crank (crank) and other components. [0004] A bearing is a mechanical device designed to provide a pivotal connection between a pul...
