Machine design
A solid shaft made from AISI 1040 cold-drawn steel is used to carry two V-belt, as shown in the Fig. 3. Pulley A receives power from a motor through a belt, with the belt tensions shown in Fig. 3. The power is transmitted through the shaft and delivered to the belt through pulley B. Assume the belt tension on the loose side is 10 percent of the tension on the tight side.
The worm shaft shown in the figure transmits 1-kW at 500 rev/min. A static forceanalysis results are also shown in the figure. Bearing A is to be an angular-contact ballbearing mounted to take the 2.75 kN thrust load. The bearing at B is to take only theradial load, so a straight roller bearing will be employed. Use an application factor of1.2, a desired life of 25 kh, and a combined reliability goal of 0.99. (a)Specify each bearing by giving all required charecteristics. (b) Determine the radial and thrust components of loads on each bearing. (c) Make a design assessment for each bearing and of the system.
