Description
Technical field
A kind of bearing arrangement technical field is the utility model is related to, more particularly to a kind of wide-angle self-aligning bearing.
Background technology
Traditional self-aligning bearing, it include the inner ring with biserial raceway, the outer ring with spherical raceway, two row be assembled in
Roller and retainer between the raceway of inner ring and the raceway of outer ring.Spherical raceway wherein on outer ring is Integral ball
Face, and the biserial spherical raceway on inner ring is the spherical raceway independently formed.Biserial sphere rail on inner ring
Road be symmetrical arranged and in axial direction it is high in the middle and low on both ends in the form of, therefore two row rollers installation after, in two row rollers pair
A spherical profile matched with the spherical raceway of outer ring should be formed between the radial outside of bearing, is realized around outer ring
Central axis circumferentially revolve round the sun while can also a certain degree of centre of sphere around outer race track relatively radially deviate in outer ring
Mandrel line rotates toward other directions, reaches the aligning made between inner ring and outer ring.But the self-aligning bearing of this structure is using
When, due to roller be relative positioning in two row raceways on the inner ring, therefore when inner ring with respect to outer ring axial deflection when,
Two row rollers can not be deviated from outside the spherical raceway of outer ring, and such case can cause the contact surface of roller and spherical raceway to subtract
It is small, make stress concentration, cause bearing damage, moreover, roller is also resulted under high speed conditions throws the retainer that flies out.
Utility model content
The purpose of this utility model is to provide a kind of wide-angle self-aligning bearing, and its technical problem to be solved is：
In traditional self-aligning bearing, roller is relatively fixed in two row raceways of inner ring, thus the central axis of inner ring can not with it is outer
The central axis deviation of circle is too big, and part roller otherwise can be caused to deviate from the spherical raceway of outer ring, and then influences answering for bearing
Power performance.
In order to solve the above technical problems, the utility model provides a kind of wide-angle self-aligning bearing, it include outer ring, inner ring,
Retainer and multiple balls, the inner ring is coaxial to be arranged in the outer ring, the retainer be located at the outer ring with it is interior
Between circle, the madial wall of the outer ring is the sphere of indent, and the sphere of indent forms one on the outer ring and surrounds the outer ring
The ring-type spherical raceway of central axis, the lateral wall of the inner ring are the sphere of convex arch, and the lateral wall of the inner ring and outer ring
Madial wall be concentric sphere, multiple balls are divided into the lateral wall of at least two groups setting inner rings and the inner side of outer ring
Between wall, ball described in each group around the outer ring central axis circular array be distributed, the diameter of the ball with
The lateral wall of the inner ring to the distance between the madial wall of outer ring matches, and the retainer is the entity barrel shell of individual layer, institute
It is the sphere concentric with the ring-type spherical raceway to state the medial surface of retainer and lateral surface, is corresponded on the retainer each
The individual ball offers one-to-one pocket hole respectively, and each described ball is corresponded in a pocket hole respectively.
It is preferable over：The lateral surface of the retainer is outer not less than the inner ring to the distance between the outer ring madial wall
Side wall corresponds to the hole of the retainer lateral surface in the pocket hole to the half of distance between the madial wall of the outer ring
Mouth diameter is not less than the diameter of the ball, and the orifice diameter of the retainer medial surface is corresponded in the pocket hole less than described
The diameter of ball, the ball pocket are clipped between the madial wall of the outer ring and the pocket hole.
It is preferable over：The outer ring is axially fixedly installed ring shaped retainers on two end faces, the ring shaped retainers it is interior
Footpath is less than overall diameter, the external diameter more than inner ring axial direction both ends at retainer axial direction both ends.
It is preferable over：The axially uniform lateral wall that is divided into the three group setting inner ring of multiple balls along the outer ring
Between the madial wall of outer ring.
Compared with prior art, the beneficial effects of the utility model are：The retainer is entered using two ring shaped retainers
Row limitation, makes it to surround central axis rotation, and then all balls are carried out axially and radially by the retainer
Limitation, the ball can only in the ring-type spherical raceway around outer ring central axis roll revolution, hence in so that institute
Stating inner ring can arbitrarily rotate in the outer ring around the centre of sphere, the situation that the axle of grafting does not disturb with other positions in inner ring
The angle of aligning can be greatly increased down, the integrated stress performance without influenceing bearing.
