Chapter 17, Problem 26P

A four-strand no. 40 roller chain transmits power from a 21-tooth driving sprocket to an 84-tooth driven sprocket. The angular speed of the driving sprocket is 2000 rev/min.

  1. (a)   Estimate the chain length if the center-to-center distance has to be about 20 in.
  2. (b)   Neglecting chain length effects, estimate the tabulated horsepower entry H tab for a 20 000-h life goal.
  3. (c)   Estimate the allowable horsepower for a 20 000-h life.
  4. (d)   Estimate the tension in the chain at the allowable power.

There are two pairs of closed soft tooth surface spur gears A and B Parameters of A: modulus m = 2mm, number of teeth Z, = 40,Z, = 90, width of teeth b =60mm. %3D Parameters of B: modulus m = 4mm, number of teeth Z, = 20,Z, = 45, width of teeth b = 60mm. %3D The accuracy of the two pairs of gears is grade 8, and other conditions are the same. Try to compare the contact fatigue strength and bending fatigue strength of the two pairs of gears? And explain the reason?
A wheel of mass m, radius r and radius of gyration k is rolling along a horizontal road with hub velocity v in the +ve x direction. Brakes are applied to the wheel, providing a torque of -M, slowing the vehicle to rest. Assuming that the wheel rolls without slipping and the hub position starts at x=0, where m = 10 kg, r = 0.85 m, k = 0.595 m, v = 5m/s, M = 21 Nm, g = 9.81 m/s^2 a) Find the constant acceleration, (ax) of the wheel hub b) Find the minimum static coefficient of friction (mu) between the road and the wheel c) Find the stopping distance (smax) and time (tmax)
A spur pinion of pitch diameter 50 mm rotates at 200 rad/s and transmits 3 kW power. The pressure angle of the tooth of the pinion is 20° Assuming that only one pair of the teeth is in contact the total force (in Newton) exerted by a tooth of the pinion on the tooth on a mating gear is...
