A steel gear is to be mounted on a solid steel shaft using an interference fit H7/s6. The gear has 17 teeth cut to a module of m=5 mm. The shaft diameter is 52 mm. The gear face width is 50 mm. What is the torque transmission capacity for this mounting? Assume a steel-on-steel friction coefficient of 0.6. The gear does not have protruding hub and it can be treated as a disc the thickness of which is equal to the face width of the gear teeth.Answer in N-m. (Acceptance limits=+/-10%) The shaft rotating at 750 rpm carries a spur gear B with 79 teeth and a module of 5 mm. The teeth are 20, full-depth, involute form. The gear receives 25 kW from a pinion directly above it as shown. The shaft transmits the power to a **V-belt** sheave of diameter Ds=300 mm. The belts are oriented downwards at an angle of 40 $^0$ with the horizontal. Calculate the bending moment at B in N-m. The dimensions are a=250, b=250, and c=150 in mm.
