Description

A kind of plane rolling formula integral cage

Technical field：

It the utility model is related to joint and seek bearing apparatus technical field, and in particular to a kind of plane rolling formula is integrally kept Frame.

Background technology：

Joint ball bearing is a kind of spherical bearing, and its sliding contact surface is an Internal Spherical Surface and a spherical outside surface, It can need to make relative gyration between any angle rotary oscillation, internal and external spherical surfaces during motion, radial load, axle can be born To load or radially, axially simultaneous joint load.With the rapid emergence of Chinese Railway cause, rock tunnel(ling) machine, Shield machine has also obtained unprecedented development, critical piece of the joint ball bearing as shield machine, widely should also obtain With.

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.

Embodiment：

In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, under Face combines and is specifically illustrating, and the utility model is expanded on further.

Embodiment 1：

As depicted in figs. 1 and 2：A kind of plane rolling formula integral cage, by retainer body 1, plug screw 2, elastic mattress 3, Arc spacer 4 and ball 5 form.Steel-ball limiting square hole is uniformly opened up on the holding frame body 1, and is justified in retainer body 1 4 groups of A screwed holes 11 and B screwed holes 12 are opened up on week, A screwed holes 11 and B screwed holes 12 penetrate, and the both ends of A screwed holes 11 have Two plug screws 2, elastic mattress 3, arc spacer 4 and ball 5 are equipped with successively between two plug screws, wherein the position between two balls leads to It is adjustable to cross elastic mattress 3, band glue screws between plug screw 2 and A screwed holes 11, and ensures that ball 5 can rotate flexibly, the B screw threads Elastic mattress 3, arc spacer 4 and plug screw 2 are equipped with hole 12 successively, is screwed between plug screw 2 and B screwed holes 12 and with glue, 180 It is adjustable to spend the relative position of two groups of balls 5 in direction, and rotates flexible.

Embodiment 2：

：Invention specific implementation is as follows：

The spherical outside surface 6 of joint ball bearing is engaged by gear with Internal Spherical Surface and produces relative motion, and Internal Spherical Surface is three organ timbering formulas Structure, including outer lower ring 7, outer upper ring gear 8 and inner ring 10, outer lower ring 7 and outer upper ring gear 8 are bolted and are integrated, and keep It is placed in the raceway between outer lower ring 7, outer upper ring gear 8 and inner ring 10, the ball 5 of retainer upper and lower end face and the rolling of periphery Pearl 5 contacts with roller surface respectively, and when the Internal Spherical Surface being made up of outer lower ring 7 and outer upper ring gear 8 produces motion, ball 5 is in raceway Rolled on face, four groups of position limiting structures of retainer, it is ensured that the relative position relation between retainer and raceway, make retainer exist Inclination and sliding will not be produced in raceway, ensure that relative position of the rolling element 9 in raceway.Joint ball bearing working process In, rolling element 9 does not offset and not tilted in the spacing square hole of retainer so that joint ball bearing is not in that rotation difficulty is To stuck phenomenon.

The advantages of general principle and principal character of the present utility model and the utility model has been shown and described above.One's own profession The technical staff of industry is it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification Simply illustrate principle of the present utility model, on the premise of the spirit and scope of the utility model is not departed from, the utility model is also Various changes and modifications are had, these changes and improvements are both fallen within claimed the scope of the utility model.The utility model Claimed scope is by appended claims and its equivalent thereof.
