Claims

[Scope of utility model registration request]

The rotating body 1 is rotatably mounted on a traveling body 3 via a turntable bearing 2, and runs on an inner ring 2c inscribed through an outer ring 2a of a turntable bearing 2 fixed to the lower surface of the rotating body 1 and a rolling element 2b. A pinion fixed to the upper surface of the body 3 and meshing with an internal gear 2d carved on the inner peripheral surface of the inner ring 2c is vertically provided on the lower surface of the rotating body 1, and the rotating body 1 is rotated by driving the pinion. In the revolving body driving device for construction machinery, two proximity switches 4a and 4b are fixed to the lower surface of the revolving body 1 at a distance from each other, facing the tooth tips of the internal gear 2d, and one of the proximity switches 4a When the axis of the other proximity switch 4b coincides with the axis of the tooth tip, the axis of the other proximity switch 4b is deviated from the axis of the tooth tip.
A running direction confirmation device for construction machinery, characterized in that the angular displacement between the rotating body 1 and the traveling body 3 is calculated and displayed based on the output signal of the rotating body 1 and the traveling body 3.
