View Answer Explanation
The shortest distance measured along the normal to the helix between corresponding points on the adjacent teeth is called ____________
Two spiral gears have a normal module of 10 mm and the angle between the skew shaft axes is 50°. The driver has 20 teeth and the helix angle of it is 30°. If the velocity ratio is 1/3 and the driver as well as the follower are both left handed, find the centre distance between the shafts.
The centre distance between two meshing gears is 250 mm and the angle between the shafts is 60°. The normal circular pitch is 10 mm and the gear ratio is 2. Ψ1 = 35°. Find the value of number of teeth on both the wheels.
The centre distance between two meshing gears is 250 mm and the angle between the shafts is 60°. The normal circular pitch is 10 mm and the gear ratio is 2. Ψ1 = 35°. Find the exact centre distance.
The centre distance between two meshing gears is 250 mm and the angle between the shafts is 60°. The normal circular pitch is 10 mm and the gear ratio is 2. Ψ1 = 35°.Find the efficiency if the friction angle is 6°.
The shaft angle of two helical gears is 60°. The normal module is 6 mm. The larger gear has 50 teeth and the gear ratio is 2. The centre distance is 300 mm. Find the helix angles of the two gears.
Find the spiral angles of the two helical gears for maximum efficiency if the shaft angle is 100° and the friction angle is 10°.
Find the normal circular pitch as well as the normal module if the larger gear has 40 teeth and the gear ratio is 4. The helix angle is 20° and the shaft angle is 50°. Assume the centre distance between the gears to be 200 mm.
The normal circular pitch of two helical gears in a mesh is 7 mm. If the number of teeth on the smaller gear is 22 and the gear ratio is 2, find the pitch diameters of the gears. Ψ₁ = 40° and Ψ₂ = 25°.
For two gears having shaft angle 90° and friction angle 6°, find the maximum efficiency of the helical gears.
