The role of hunting tooth or hunting cog in a gear transmission is that it
A triple threaded worm has teeth of 6 mm module and pitch circle diameter of 50 mm. If the worm gear has 20 teeth of 200 and the coefficient of friction of the worm gearing is 0.05. The lead angle of worm is
In the formulation of lewis equation for toothed gearing. It is assumed that tangential tooth load FT Exacts of the
The dynamic load on a gear is due to:
1. Inaccuracies of tooth spacing.
2. Irregularities in tooth profile.
3. Deflection of the teeth under load.
4. Type of service (i.e., intermittent, one shift per day, continuous per day).
Which of the above statements are correct?
Large speed reductions (greater than 20) in one stage of a gear train are possible through
A spur gear transmits 10 kW at a pitch line velocity of 10 m/s; driving gear has a diameter of 1.0 m. Find the tangential force between the driver and the follower, and the transmitted torque respectively.
