Abstract
A lengthened bearing sleeve assembly includes a bearing pedestal, linear bearings positioned in the bearing pedestal, and retainer rings positioned at the two ends of the bearing pedestal, and is characterized in that two or more linear bearings are fixed in an inner cavity of the bearing pedestal; and a choke nipple screw hole is arranged on the side wall of the inner cavity of the bearing pedestal between the two linear bearings. In the utility model, the plurality of linear bearings are fixed in the same lengthened bearing pedestal, as the outer diameter of each bearing has high machining precision, the bearings are in transition fit with the lengthened bearing sleeve and installed in the same bearing sleeve, the bearings are coaxial; and meanwhile, an oil filler pipe is arranged between the two bearings of the lengthened bearing sleeve, lubricant can be injected at any time, so that the bearing clamping stagnation can be avoided after a long-time operation, and the service life of the whole assembly is greatly prolonged.
Description
Technical field
The utility model relates to a kind of bearing sleeve, particularly a kind of extended type linear bearing cover for seat assembly.
Background technique
In the supporting application of conventional linear bearing finished product, be installed to linear bearing earlier in the bearing sleeve that tolerance matches, being that linear axis cooperates carries out straight line motion, and bearing support reaches the effect of playing rigid bearing and location at this.But when some special machine coordinative composition of equipments; When requirement is used two covers or quadruplet linear bearing cover for seat assembly at same position,, cause that tolerance grade has bigger difference as with a plurality of common single bearing sleeve assemblies; After being that linear axis cooperates; Because each trueness error is different, it is dumb or respectively organize in the cover for seat motion and catching phenomenon occurs bearing movable when the linear axis straight line motion, will to occur, will produce when serious that vibration is big, the phenomenon of motion shakiness; So not only can not guarantee straight-line flexibility, also shorten the working life of bearing sleeve assembly greatly.How to make same position a plurality of linear bearings when motion held stationary operation be to need the problem that solves at present.
Summary of the invention
The utility model proposes a kind of extended type bearing sleeve assembly of a plurality of linear bearings held stationary motion when straight line motion that makes same position to the problems referred to above.
A kind of extended type bearing sleeve assembly; It comprises bearing support, be positioned at the linear bearing of bearing support and be positioned at the back-up ring at bearing support two ends; The inner cavity internal fixation that it is characterized in that said bearing support has the linear bearing more than two or two, on the inner cavity sidewall of the bearing support between two linear bearings, is provided with the oil nozzle screw.
The beneficial effect of the utility model is for to be fixed on a plurality of linear bearings in the same extended type bearing support, because the bearing outside diameter machining accuracy is high, cooperates with the extended type cover for seat to be transition fit; Be installed in the same bearing sleeve; Basically can reach alignment, between two bearings of extended type cover for seat, be provided with tank filler sleeve, the lubricant oil of can annotating at any time simultaneously; Make bearing clamping stagnation not take place, thereby improve greatly the working life of whole assembly at prolonged exercise.
Description of drawings
Fig. 1 is the general assembly drawing of the utility model.
Fig. 2 is the novel exploded view of this use.
Embodiment
Below in conjunction with accompanying drawing embodiment is done further elaboration.
Referring to Fig. 1, shown in Figure 2, it comprises extended type bearing sleeve assembly bearing support 1, is positioned at the linear bearing 2 of bearing support 1 and is positioned at the back-up ring 3 at bearing support 1 two ends.In the bearing support 1 is axial inner cavity 9; Two linear bearings 2 are separately fixed at the two ends of the inner cavity 9 of bearing support 1; Be provided with retaining rings 5 in the middle of the inner cavity 9 between two linear bearings 2; Two linear bearings 2 can cooperate closelyr about making, also are provided with an oil nozzle screw 4 on inner cavity 9 sidewalls of the bearing support 1 between two linear bearings 2, and oil nozzle 6 passes through this hole and is fixedly connected with bearing support 1.Inner cavity 9 two ends of bearing support 1 respectively are provided with a locking groove 8; Respectively be provided with a back-up ring 3 in the two ends locking groove 8; Said back-up ring 3 has prevented two linear bearings, 2 outer scurrying, and bearing support 1 is the mounting hole 7 and miscellaneous part mount of vertical arrangement through its both sides and bearing support 1.
When the linear bearing 2 placed in the inner cavity 9 of bearing support 1 more than two; Be equipped with retaining rings 5 in the middle of the inner cavity 9 between two linear bearings 2; Make retaining ring about 5 two linear bearings 2 closely cooperate; Also be provided with an oil nozzle screw 4 on inner cavity 9 sidewalls of the bearing support 1 between two linear bearings 2, oil nozzle 6 is fixedly connected with bearing support 1 through this hole.Inner cavity 9 two ends of bearing support 1 respectively are provided with a locking groove 8; Respectively be provided with a back-up ring 3 in the two ends locking groove 8; Said back-up ring 3 has prevented linear bearing 2 outer the scurrying of the left and right sides, and bearing support 1 is the mounting hole 7 and miscellaneous part mount of vertical arrangement through its both sides and bearing support 1.
Claims (2)
1. extended type bearing sleeve assembly; It comprises bearing support (1), be positioned at the linear bearing (2) of bearing support (1) and be positioned at the back-up ring (3) at bearing support (1) two ends; Inner cavity (9) internal fixation that it is characterized in that said bearing support (1) has the linear bearing (2) more than two or two, on inner cavity (9) sidewall of the bearing support (1) between two linear bearings (2), is provided with oil nozzle screw (4).
