FHP electric motor driven worm gear - is coupled by spring wound around motor shaft with flat drive loop for connector

摘要

The wormgear drive powered by a miniature electric motor (6) has the driving worm (2) mounted between the flanges of a channel-shaped support (1) and in line with the motor drive shaft (7). Wound around the outer end of the shaft is a spring (8) forming a drive member. The outer end of this spring is formed into an elongated loop which fits inside a slot across the end of a block (12) on the end of the driving worm. This block rotates in a bearing mounted in a flange of the support which is also connected to a spacer member (4) mounted on the end of the motor.
