Title:
ベルト伝動装置
Document Type and Number:
Japanese Patent JP4424747
Kind Code:
B2
Abstract:
[Purpose] A belt drive system, in which a drive belt 20 is wrapped between a drive pulley 1 drivingly connected to a drive source 11 and a driven pulley 2 connected to an driven unit 12 via a joint 32 provided to stop torque transmission when receiving a load equal to or over a predetermined value and torque is transmitted via the drive belt 20 from the drive pulley 1 to the driven pulley 2, ensures that when the driven unit 12 malfunctions, the joint 32 stops the torque transmission without unnecessarily increasing the coefficient of friction against the driven pulley 2 or the belt tension. [Solution] The belt drive system is configured so that when a slip corresponding to the load on the joint 32 equal to or over the predetermined value occurs between the drive belt 20 and the driven pulley 2, the coefficient of friction between the drive belt 20 and the driven pulley 2 becomes higher than that before the slip occurs.
