Required information Design a cylindrical worm-gear mesh to connect a squirrel-cage induction motor to a liquid agitator. The motor speed V1? is 1125rev/min, and the velocity ratio is to be 10:1. The output power requirement HO? is 24hp. The shaft axes are 90? to each other. An overload factor KO? (see Table 15-2) makes allowance for external dynamic excursions of load from the nominal or average load Wt. For this service, KO?=1.25 is appropriate. Additionally, a design factor nd? of 1.1 is to be included to address other unquantifiable risks. Use the Buckingham method to complete the design and assume that there is a fan. Assume NW?=3, the application factor Ka?=1.25, and the ambient temperature ta? is 70?F. The worm material is high-test cast iron. The gear material is cast bronze. Use the following values for design decisions: dW?=3.6in,pX?=1.75in,Fe?=2in,FG?=2.4in, and A=2500in2. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Determine the following values. (You must provide an answer before moving to the next part.) The worm velocity VW? is The gear velocity VG? is The sliding velocity VS? is The coefficient of friction f is ft/min. ft/min. ft/min. The efficiency e is %.
