Traction elevator system having cable groove in drive sheave formed by spaced, elastically deflectable metallic ring members

摘要

An elevator system including an elevator car, a counterweight, metallic ropes or cables interconnecting the elevator car and counterweight, and a traction drive which includes a drive sheave. The drive sheave includes metallic cable groove members secured to its periphery which support and guide the cables in an axially compliant arrangement which increases the traction efficiency and reduces cable and groove wear.
