Under normal circumstances, joint ball bearing has oscillating motion, banking motion and rotary motion during use.
The spherical outside surface of joint ball bearing is engaged by gear with Internal Spherical Surface and produces relative motion, and Internal Spherical Surface is three row's pole structures, including
Outer lower ring, outer upper ring gear and inner ring, outer lower ring and outer upper ring gear are bolted and are integrated, and holding is placed on outer lower ring, outer
In raceway between upper ring gear and inner ring, rolling element is placed in the positioning hole of retainer, and inside and outside spherical surface produces relative motion
During, the rolling element between outer lower ring, outer upper ring gear and inner ring can also move therewith, and the retainer of traditional handicraft uses process
In, contacted with roller surface, relative to slide, frictional force is big in motion process, and noise is big, greatly reduces the use of joint ball bearing
Life-span.
Utility model content:
Technical problem to be solved in the utility model is to provide a kind of plane rolling formula simple in construction, easy to use
Integral cage, the retainer realize joint ball bearing in use, inside and outside spherical surface flexible rotating, and it is tired to occur without rotation
Difficult and stuck situation.
Technical problem to be solved in the utility model is realized using following technical scheme:
A kind of plane rolling formula integral cage, including retainer body, plug screw, elastic mattress, arc spacer, ball, institute
It is ring shape structure to state and keep frame body, and 4 groups of A screwed holes and 4 groups of B screwed holes, the A spiral shells are opened up on retainer body circumference
There are two plug screws at pit both ends, are equipped with elastic mattress, arc spacer and ball between two plug screws successively, and the ball is provided with two
It is individual, elastic mattress, arc spacer and plug screw are equipped with successively in the B screwed holes;
Steel-ball limiting square hole is uniformly opened up in wherein described retainer main body;
Further technology, the A screwed holes penetrate with B screwed holes;
Further technology, the position between two balls in the A screwed holes is adjustable by elastic mattress;
Further technology, band glue screws between plug screw and A screwed holes, and ensures that ball can rotate flexibly;
Further technology, screw between plug screw and B screwed holes and with glue, and the phase of two groups of balls in 180 degree direction
It is adjustable to position, and rotate flexible.
The spherical outside surface of joint ball bearing is engaged by gear with Internal Spherical Surface and produces relative motion, and Internal Spherical Surface is three organ timbering formula knots
Structure, including outer lower ring, outer upper ring gear and inner ring, outer lower ring and outer upper ring gear are bolted and are integrated, and holding is placed on outer
In raceway between Xia Quan, outer upper ring gear and inner ring, the ball of retainer upper and lower end face and the ball of periphery respectively with raceway
Face contacts, and when the Internal Spherical Surface being made up of outer lower ring and outer upper ring gear produces motion, ball rolls on roller surface, retainer four
Group position limiting structure, it is ensured that the relative position relation between retainer and raceway, make retainer not produced in raceway and incline
Tiltedly and sliding, it ensure that relative position of the rolling element in raceway, during joint ball bearing working, rolling element is in retainer
In spacing square hole, do not offset and do not tilt so that joint ball bearing is not in the difficult or even stuck phenomenon of rotation.
The beneficial effects of the utility model are:Simple in construction, easy to use, the retainer, which realizes joint ball bearing, to be made
During, inside and outside spherical surface flexible rotating, occur without and rotate difficult and stuck situation.
