Abstract

Shown is an elastic-core pulley mounted on a rotating shaft. The pulley consists of a hard outer surface 10, an elastic core 12, and two semicircular hardened hubs 14 and 16. The inner diameter formed by the hubs 14 and 16 is smaller than the outer diameter of the shaft 18. Shaft 18 contains a pin 20 that passes through the shaft and protrudes on each side of the shaft. When the pulley is mounted on the shaft, pin 20 engages detents 22 in the hubs 14 and 16 on opposite sides of the shaft.

Elastic Core Pulley

Shown is an elastic-core pulley mounted on a rotating shaft. The pulley consists of a hard outer surface 10, an elastic core 12, and two semicircular hardened hubs 14 and 16. The inner diameter formed by the hubs 14 and 16 is smaller than the outer diameter of the shaft 18. Shaft 18 contains a pin 20 that passes through the shaft and protrudes on each side of the shaft. When the pulley is mounted on the shaft, pin 20 engages detents 22 in the hubs 14 and 16 on opposite sides of the shaft.

To mount the pulley on the shaft, the gap between the hubs 14 and 16 is aligned with the pin 20, and the pulley is pushed onto the shaft 18. When detents 22 reach the protrusion of pin 20 on each side of the shaft 18, the pulley snaps onto the shaft. With the pulley on the shaft, elastic material 12 provides a compression load on the hubs 14 and 16 to press them against the shaft 18.
