Required information Design a cylindrical worm-gear mesh to connect a squirrel-cage induction motor to a liquid agitator. The motor speed is , and the velocity ratio is to be 10:1. The output power requirement is . The shaft axes are to each other. An overload factor (see Table 15-2) makes allowance for external dynamic excursions of load from the nominal or average load . For this service, is appropriate. Additionally, a design factor 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 , the application factor , and the ambient temperature is . The worm material is high-test cast iron. The gear material is cast bronze. Use the following values for design decisions: , and . 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 is The gear velocity is The sliding velocity is The coefficient of friction is . . . The efficiency is .
