Abstract
PURPOSE: To obtain a wheel for a hourglass-shaped worm that will be in gear with the hourglass-shaped worm, wherein the depth of the enveloping surface of each of the gear teeth thereof is modified to have a rather shallow depth so that when they are assembled, even if there exists displacement, extremely biased abutting of the tooth surfaces is prevented.
CONSTITUTION: The wheel 16 that will be meshed with the hourglass worm 14 has an enveloping surface 20 on the tooth surface of each tooth 18. In this wheel 16, compared with the prior enveloping surface 20, the enveloping surface 52 of each tooth 18 has a width W the same as the prior art, and a depth D that is modified to become rather shallower than the depth D' of the enveloping surface 20. Thus, when the hourglass-shaped worm 14 is assembled with it biased by ΔZ in a direction of Z (direction of width of the teeth of the wheel 16), extremely biased abutting can be prevented. Therefore, the adjustment of assembling in the direction of the width of the teeth of the wheel 16 can be performed quite easily.
