Tensioning device for tightening a traction mechanism (TM) in a traction mechanism gearbox, especially a driving belt in a driving belt transmission, has a hub part and a wheel part assigned to the hub part to work together with the TM

摘要

#CMT# #/CMT# A traction mechanism tightening device (100) has hub (102) and wheel (108) parts. The disk-shaped hub part can have a torque-proof link with a shaft or an outer ring on a rolling bearing as well as a tubular gudgeon (104) parallel to an axis and in the center. On the end side, the tubular gudgeon has a retaining contour with two parallel surfaces. #CMT#USE : #/CMT# For tightening a traction mechanism in a traction mechanism gearbox, especially a driving belt in a driving belt transmission for an internal combustion engine. #CMT#ADVANTAGE : #/CMT# A wheel part can be shifted radially between traction mechanism mounting and operating positions compared to a hub part. Between the hub part and the wheel part there is a connecting contour that has radial movement and a torque-proof positive fit as well as a device for driving additional units in an internal combustion engine. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows hub and wheel parts for a tensioning device with a connecting contour with radial movement and a torque-proof positive fit. 100 : Traction mechanism tightening device 102 : Hub part 104 : Tubular gudgeon 106 : Slot 108 : Wheel part 110 : Axial safety ring 112 : Through-hole.
