A PCM transmitter sends out a 12-bit serial digital signal with 5 V corresponding to a 1 and 0 V corresponding to a 0. The signal passes over a transmission….
Design a suitable crankshaft and construct good engineering sketches of the final design.
1.A straddle-mounted crankshaft for a belt-driven singlecylinder refrigeration compressor is to be designed to meet the following specifications:
a. The force on the connecting rod bearing ranges from 3500 lb down to 1300 lb up.
b. The belt tension ratio is .
c. The crank throw is 2.2 inches.
d. Allowable maximum bearing pressure is 700 psi.
e. The pulley pitch diameter 8.0 inches.
f. All bearings are to be made alike.
g. Main bearings are 12 inches apart center-to-center, with the connecting rod bearing halfway between.
h. The pulley overhangs the main bearing 4 inches. Design a suitable crankshaft and construct good engineering sketches of the final design.
