For Problems 1-4 and 7, determine the required key geometry: length, width, and height. Use SAE 1018 steel for the keys if a satisfactory design can be achieved. If not, use a higher- strength material from Table 11-4. Unless otherwise stated, assume that the key material is weakest when compared with the shaft material or the mating elements. 1. Specify a key for a gear to be mounted on a shaft with a 2.00 in diameter. The gear transmits 21 000 lb-in of torque and has a hub length of 4.00 in. See Figure P11-1. 2. Specify a key for a gear carrying 21 000 lb-in of torque if it is mounted on a 3.60-in-diameter shaft. The hub length of the gear is 4.00 in. . mun mm
FIG FIGURE P11-3 Belt sheave, shaft, and key for COI Problem 11-3 22. 23 3. A V-belt sheave transmits 1112 lb in of torque to a 1.75-in-diameter shaft. The sheave is made from ASTM class 20 cast iron and has a hub length of 1.75 in. See 4. A chain sprocket delivers 110 hp to a shaft at a rotational speed of 1700 rpm. The sprocket has a bore diameter of 2.50 in. The hub length is 3.25 in. 24 Figure P11-3. 25
