Section 29.145 - Pulleys

Current through Register Vol. 54, No. 38, September 21, 2024

(a) Alignment. Pulleys should be kept in proper alignment to keep belts from running off.

(b) Crown-faced. Both driving and driven pulleys carrying a nonshifting belt should have crowned faces.

(c) Cast iron. Cast iron pulleys should be tested frequently with a hammer to disclose cracks in rim or spokes. It should be borne in mind that the sound is usually very different if the belt is or is not on the pulley. Pulleys with small pieces broken out of rim should not be used. The rough edges formed by pieces broken out of the pulley rim offer a decided accident hazard in case any one should come in contact with the rough edge of the pulley rim. Considerable unnecessary wear on the belt is also caused.

(d) Split. Split pulleys should be inspected to ascertain if all bolts holding together the sections of the pulley are tight.
