Bearing, precession bearing, precession bearing gyroscope and gyroscope precession type active stabilizing device using precession bearing gyroscope

Abstract

The invention discloses a precession bearing, plane raceways, conical raceways and thrust angular contact annular spherical raceways of annular limiting parts of third steps of a left outer ring and a right outer ring of an outer bearing ring are arranged, and conical raceways, thrust angular contact annular spherical raceways and plane raceways of axial left and right side surfaces of an inner bearing ring are arranged; two rows of first balls in the radial ball ring, two rows of second balls in the axial direction and two rows of third annular slope balls in the axial direction are arranged, the left side and the right side, opposite to each other, of the inner ring and the outer ring are arranged in the axial distance, and a left row of balls and a right row of balls are arranged on different opposite raceways of the inner ring and the outer ring. During installing, the left and right rows of balls form a splayed shape. Each row of balls are tangent to the conical raceway, the thrust angular contact annular spherical raceway and the plane raceway, the rotation axis of the inner ring and the rotation axis of the outer ring are relatively inclined, namely, the plane raceway of the inner ring and the plane raceway of the outer ring are relatively inclined, and when the inner ring rotates, the left row of balls and the right row of balls which are relatively inclined drive the outer ring to do rotate and swing motion, commonly known as precession.

Problems solved by technology

In addition, during the movement of the workpiece table in the X and Y planes, the acceleration and deceleration movement away from the central axis will cause the workpiece table to twist along the Z axis, which cannot be ignored for high-precision positioning, and measures need to be taken to suppress it.
