Title:
PULLEY DEVICE WITH BUILT-IN ONE-WAY CLUTCH
Document Type and Number:
Japanese Patent JP2004225751
Kind Code:
A
Abstract:
To enhance followability of a pulley 2a with respect to an endless belt when the pulley 2a is rotated and driven by the endless belt, to reduce load torque of a roller clutch 3 when a sleeve 1 is rotated and driven by a drive shaft, and to make it easier to emit heat generated by the roller clutch 3 and support bearings 4, 4 outside via the pulley 2a.
The pulley 2a is made by metal injection of light alloy of which thermal conductivity is larger than 59 W/(m×K) (ex. a magnesium alloy or the like).
