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

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.

2020-8-14 Pulley diameters and shaft diameters should be selected using tools such as ANSI/CEMA B105.1-2003 (SEE APPENDIX A). The following application variables need to be considered in the selection of both the pulley outer diameter and the shaft diameter: Excessive shaft deflection occurring as a result of an undersized shaft (exaggerated for effect).

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.
