5 kW of power at 720 rpm is supplied to the worm shaft, as shown in Fig. 20.10. The worm gear drive is designated as,
2/40/10/5
The worm has right-hand threads and the pressure angle is 20°. The worm wheel is mounted between two bearings A and B. It can be assumed that the bearing A is located at the origin of the co-ordinate system and the bearing B takes complete thrust load.
Determine the reactions at the two bearings.
