  • Sleeve bearing
  • Bush bearing
  • Roller bearing
Q2 | Radial distance from the top to the pitch circle for a tooth is known as
  • working depth
  • dedendum
  • addendum
  • None of the above
  • None of the above
Q3 | Higher pressure angle results in
  • Narrow base and weaker teeth
  • Weaker teeth
  • Non-uniform motion transmission
  • Bigger size of gear teeth
  • Wider base and stronger teeth
Q4 | In a radial cam with a roller on follwer the prime circle can be defined as
  • the smallest circle tangent to the pitch curve
  • the smallest circle tangent to the cam profile
  • a circle drawn with radius equal to the distance between the pitch point and the centre of base circle
  • None of the above
  • None of the above
Q5 | Identify the incorrect statement in case of cycloidal gears
  • No lubrication needed
  • Interference does not exist
  • Have less wear
  • Interference exists
  • Ease in transmitting variable loads
Q6 | Which one of the following is not applicable to involute profile
  • The angular velocity ratio when tow involutes are in mesh, is inversely proportional to the size of the base circles
  • No involute has a pressure angle until it is brought in contact with other mating involute
  • Involute is the only tooth form that is not sensitive to centre distance of their base circles
  • The shape of the involute profile is dependent only on the dimensions of the base circle
  • The pitch diameters of mating involutes are inversely proportional to their base circle diameters
