(5) freely rotated up and down within the specific limits on contact surface, bent caused by compensation axle, Bearning mechanism is protected with axle (7)
Good axis concentricity is held, and can make Bearning mechanism in itself not by radial direction moment loading.It is conjugated the upper bearing sleeve of bearing holder (housing, cover) (2)
(8) and lower bearing sleeve (9) contact surface be groove insertion structure type (a), ensure that upper bearing sleeve (8) and lower bearing sleeve
(9) will not relatively move, and it is gland integrative-structure form (c) to be conjugated bearing holder (housing, cover) (2) both ends, is integrally tied by the gland at both ends
Axle sleeve inner ring (1), outer ring (6), rolling ball bearing one (3), rolling ball bearing two (4) are positioned at conjugation bearing by configuration formula (c)
It is internal to cover (2).Wide arc gap coordinates between axle sleeve inner ring (1) and outer ring (6) are, matches somebody with somebody between axle sleeve inner ring (1) and axle (7) for gap
Close, outer ring (6) and conjugate axis bearing sleeve (2) inner surface are interference fits, and wherein the both ends of bearing inner race (1) are curved end, can
The distance of positioning and rolling ball bearing one (3) inner ring and rolling ball bearing two (4) inner ring.Both ends of the surface of the outer ring (6) close to inner surface
Indent, outer face and the dynamic ball at outer ring (6) both ends contactless with dynamic (3) inner ring of ball bearing one and rolling ball bearing two (4) inner ring
Bearing one (3) outer ring and the contact of rolling ball bearing two (4) outer ring, position ball bearing one (3) outer ring and rolling ball bearing two (4) outside
The distance between circle.
This design method is mainly characterized by, and when ensureing that axle is bent, Bearning mechanism is with bearing body not by radial load
Square acts on, and greatly adds the reliability of Bearning mechanism and bearing body.
The present invention tries out through user, and reaction effect is good.
