2020-3-4  design of the shaft is under complete control of one design group. They can take a look at each shaft design. Be-cause the design is done once for an entire series, it does not need to be looked at again until there is a de-sign change. All that the user needs to know is the load capacity as listed by CEMA. Meanwhile, in a pulley there is

ANSI/CEMA STANDARD B105.1-2015 of ANSI/CEMA

2019-6-11  Association (CEMA). The CEMA Engineering Committee reviewed the standard and decided to revise the method used for determining Drive Shaft diameters so that the method would conform to the ANSI B106.1M-1985 “Design of Transmission Shafting” standard. Also, a run-out tolerance on pulley diameters was added.

2009-10-1  In this paper we present a case study of a heavy-duty pulley that failed after 2.1 × 10 7 cycles. The pulley was installed as a take up on a continuous conveyor under a load of 350. kN transmitted by the counterweight tower.. The failure was analyzed using (a) finite element analysis by Ansys, (b) field data analysis, and (c) fracture macro examination.
