FRICTION-TYPE REVERSING MECHANISM
Click to enlargeClick to enlarge Description

Conical friction wheels a and b are keyed to shaft 1 and rotate about fixed axis A-A. Shaft 2, driven by motor 3, rotates about axis B and has spherical friction disk d keyed to it. Shaft 1 can be shifted axially along axis A-A in fixed guides D-D. When shaft 1 is shifted downward, wheel a contacts disk d and shaft 1 begins to rotate. If shaft 1 is shifted upward, wheel b contacts disk d, and both the direction and speed of shaft 1 are changed. The speed of shaft 1 can be varied by changing the angle of inclination of axis B of disk d. This is done by swivelling motor 3 about fixed axis E and clamping it in the required position with bolt 4 which moves along circular slot e. Spring 5 holds wheel b in contact with disk d.
