Abstract
PURPOSE: To smooth change-over operation, and to reduce impacts and vibration, by a mechanism wherein the titled gear is formed so that torque transmission be changed over to a spindle from drive members and balls continually put among both and a longitudinal groove of the spindle be engaged and released.
CONSTITUTION: A tap reversing gear 10 contains a casing 12, and the first (positive revolution) drive member 18, the second (reversing) drive member 34 and an intermediate drive portion 48 are housed in the casing 12. A plurality of concave grooves 30, 44 extending in the axis direction of the members are each mounted to inner circumferential walls near the other ends of the members 18, 34. A groove bottom portion of a longitudinal groove 72 installed to a portion 68, which diameter is not decreased, of a spindle 60 for driving a tap is located on the same surface as surface of portions 66, 70, which diameters are diminished. Consequently, the other side of balls 92, 100 functions as a bearing ball during the time when positive or reverse driving force is transmitted to the spindle from the drive members in one side of the balls. Thus, change-over operation is smoothed, and impacts and vibration are reduced.
