Abstract
An ultrashort linear bearing sleeve component comprises a bearing seat, a linear bearing positioned in the bearing and retaining rings arranged at the two ends of the linear bearing. The ultrashort linear bearing sleeve component has the characteristics that the bearing seat of the linear bearing is shorter than that of the linear bearing, two ends of the linear bearing expose out of the bearing seat, a retaining ring groove is arranged at either end of the linear bearing, the retaining rings tightly limit the bearing by being clamped with the retaining ring grooves, a hole is arranged at either side of the top surface of the bearing seat, and the two mounting holes are symmetrical. The ultrashort bearing seat is stably limited outside the linear bearing by the retaining rings clamped in the retaining ring grooves at the two ends of the linear bearing, as the tolerance of the inner hole can be controlled easily, the assembly and installation of the inner hole and the outer diameter of the bearing are convenient, the precision is high, seizure cannot happen during matching using; moreover, as the two mounting holes at the two sides of the top surface of the bearing are positioned on the left-right symmetrical line, the phenomenon of off center does not exist after installation with the matching equipment, and the whole component is more stable in the operation process; therefore, unnecessary loss is reduced, the service life of the whole component is prolonged, and a great deal of bearing material is saved.
Description
Technical field
The utility model relates to a kind of linear bearing cover for seat, particularly a kind of super-short linear bearing cover for seat assembly.
Background technique
In the supporting application of conventional linear bearing, be installed to linear bearing earlier in the bearing sleeve that tolerance matches, and in the draw-in groove at cover for seat two ends, jump ring be installed, prevent to scurry outside bearing is when straight line motion; In addition, corresponding positioning hole is connected fasteningly on the screw of 4 symmetries of bearing sleeve and the supporting machinery equipment with screw, and it is firm to reach installing and locating.But in actual use; With some light-duty unloading during coordinative composition of equipments; The positioning hole that 2 symmetries are only arranged on the equipment; Bearing sleeve will produce eccentric phenomena when mounted, makes whole linear bearing cover for seat assembly fixing unstable in the straight reciprocating motion process of linear axis, has directly influenced linear bearing and the stable operation and the working life of other equipment of matching.
Summary of the invention
The purpose of the utility model is to the problems referred to above, provide a kind of can with the super-short linear bearing cover for seat assembly of corollary equipment held stationary.
The design proposal of the utility model is: super-short linear bearing cover for seat assembly; Comprise bearing support, be positioned at the linear bearing of bearing support and be located at the back-up ring at linear bearing two ends; The bearing support length that it is characterized in that said linear bearing is shorter than said linear bearing, and said linear bearing two ends respectively are exposed at outside the bearing support, and said linear bearing two ends respectively are provided with a circlip groove; Back-up ring through with the circlip groove screens after bearing support is closely limited, bearing support end face both sides are provided with the mounting hole of two symmetries.
The beneficial effect of the utility model is: through the back-up ring in the circlip groove that is stuck in the linear bearing two ends will with the ultrashort bearing support stability line of linear bearing tolerance fit outside linear bearing; Because the endoporus tolerance is easy to control, and is easy for installation with the bearing outside diameter assembly, precision is high; Clamping stagnation does not take place in supporting use; And utilize monosymmetric two mounting holes of bearing support end face to be fixedly connected with corollary equipment, because of two mounting holes are to be positioned on the bilateral symmetry line of bearing support, there is not eccentric phenomena after installing with corollary equipment; Make whole bearing sleeve assembly more stable in the process of operation; Significantly reduce unnecessary loss, prolonged the working life of whole super-short linear bearing cover for seat assembly, and practiced thrift a large amount of bearing support materials.
Description of drawings
Fig. 1 is the utility model general assembly drawing.
Fig. 2 is the utility model decomposing schematic representation.
Embodiment
Below in conjunction with accompanying drawing embodiment is done further elaboration.
Referring to Fig. 1, shown in Figure 2, super-short linear bearing cover for seat assembly comprises bearing support 1, is located at the linear bearing 2 in the bearing support 1 and is located at the back-up ring 3 at linear bearing 2 two ends.Said bearing support 1 is the approximate rectangle structure of round empty cavity in, is provided with one protrudingly with the isosceles trapezoid of interior round empty cavity parallel to an axis in the middle of the rectangular end face, and the length of bearing support 1 is 1/2 of linear bearing 2 length.The middle cover of linear bearing 2 is located in this interior round empty cavity; And with interior round empty cavity tolerance fit; 1/4 place, linear bearing 2 two ends respectively is provided with a circlip groove 4, behind left and right sides back-up ring 3 and corresponding circlip groove 4 chuckings bearing support 1 is limited between two back-up rings 3, prevents linear bearing 2 play in bearing support 1.The protruding both sides of the isosceles trapezoid of bearing support 1 end face respectively be provided with one with the perpendicular mounting hole 5 in bearing support 1 bottom surface, said two mounting hole 5 bilateral symmetry run through bearing support 1, bearing support 1 is through said two mounting holes 5 and miscellaneous part mount.
