Detailed Description

(example 1)

Referring to fig. 1 and 2, the axial force-based shaft coupling bearing of the present embodiment includes a spindle 1, a first outer ring 2, a second outer ring 3, and a locking member 4.

The mandrel 1 is sleeved with the first outer ring 2 and the second outer ring 3. The outer diameters of the first outer ring 2 and the second outer ring 3 are equal, and the first outer ring 2 is arranged to be close to the second outer ring 3. Balls 6 are arranged between the first outer ring 2 and the mandrel 1 and between the second outer ring 3 and the mandrel 1 through a retainer 5. The locking member 4 is used for fixing the first outer ring 2 and the second outer ring 3.

Further, grooves 7 for mounting balls 6 are arranged between the inner wall of the first outer ring 2 and the outer wall of the mandrel 1 and between the inner wall of the second outer ring 3 and the outer wall of the mandrel 1, so that the first outer ring 2 and the second outer ring 3 can be mounted conveniently.

Further, sealing elements 8 are arranged between the end portions of the outer ring 2 and the second outer ring 3 and the mandrel 1, so that dust is prevented from entering the bearing, and the service life of the bearing is prolonged.

Furthermore, two sides of the peripheral surface of the first outer ring 2 are symmetrically provided with first semi-annular grooves 2-1. Two second semi-annular grooves 3-1 corresponding to the two first semi-annular grooves 2-1 are respectively arranged on the peripheral surface of the second outer ring 3. The first semi-annular groove 2-1 and the second semi-annular groove 3-1 form a whole annular groove. The locking piece 4 is a fixing ring. The fixing ring is clamped into the whole annular groove formed by the first half annular groove 2-1 and the second half annular groove 3-1 to fix the first outer ring 2 and the second outer ring 3, and the fixing ring is used as a locking piece, so that the structure is simple, and the operation is convenient.
