Power glider of propeller motor and drive shaft links rotary masses of shaft and propeller through slip coupling to compensate for vibration peaks as friction elements sprung onto pulley and drive hub.

摘要

The rotary mass of the propeller and the rotary mass of the motor (1) drive shaft (3) are joined through a slip coupling to compensate for torsional peaks. The slip coupling forms the entrainment connection for the hub (4) co-rotatably joined to the drive shaft (3) on one hand and the belt pulley (6) rotatably carried in the hub (4) via bearing (5). The friction element (8) of the coupling is pressed by pre-tensioning spring (10) onto hub or pulley, and the pulley is bounded axially by two friction elements (8). The first pulley joins the hub and the second element adjoins the driver element (9) as pressed by spring (10) against the friction elements (8) and pulley (6) to produce a reaction on the hub (4). Adjuster (12) tensions the spring (10) to modify the coupling.
