Abstract
The invention relates to a bidirectional roller bearing, which is characterized in that the bidirectional roller bearing comprises an annular support base, wherein a plurality of supports are uniformly arranged on the periphery of the support base in a radial way, a shaft is connected between the end faces of the adjacent supports, and the shaft is provided with a roller, and the distance from the rollers to the farthest point at the center of the support base is larger than the distance from the top surfaces of the supports to the farthest point at the center of the support base. In use, objects can be moved onto the bidirectional roller bearing along the axial direction of the bidirectional roller bearing; and the support are provided with the rollers, the outer surfaces of the rollers are higher than the support, and the friction between the objects and the rollers belongs to the rolling friction, thus the friction force is small, the objects can easily reach the predetermined position, and the roller can be driven by rotating the support base to push the objects to move along the radial direction of the bidirectional roller bearing; and the axial outlines of the rollers are arc-shaped, and the arc-shaped circle centers are coincident with the center of the support base to make the axial outer surfaces of the rollers contact with the objects at the time of rotating the support base, so that the contact area is large, and the friction force is increased so as to avoid sliding at the time of axially pushing the objects.
Description
Technical field
The present invention relates to a kind of bearing, particularly a kind of two-way Idler bearing.
Background technology
Bearing is a kind of very important parts in the contemporary mechanical equipment.Its radical function is the supported mechanical swivel, in order to the mechanical load friction coefficient of reduction equipment in transmission process.In the right angle delivery system, be applied to the carrying roller roller; It is arranged on the end of load-transfer device; The axis of carrying roller roller is parallel with the moving direction of load-transfer device; When article are delivered on the carrying roller roller by load-transfer device after, promote it by the carrying roller roller that rotates and move into next load-transfer device along direction perpendicular to load-transfer device, realize the right angle conveying.Traditional carrying roller roller directly is a roller body, and roller body is installed on the axle drive shaft, and the shortcoming of this kind structure is: when article get on the carrying roller roller from load-transfer device; Article and carrying roller roller are cliding friction; Friction force is big, and article are difficult for arriving subscribes the position, and bigger to the article bottom abrasion.
Summary of the invention
The technical matters that the present invention will solve provides the little two-way Idler bearing of a kind of friction coefficient.
For solving the problems of the technologies described above; Technical scheme of the present invention is: a kind of two-way Idler bearing, and its innovative point is: comprise the ring support seat, be radiativity on the said carrier base outer ring some supports evenly are installed; Be connected with axle between the said adjacent supports end face, on the axle roller be installed; Said roller is higher than distance greater than the solstics distance of cradle top surface apart from the carrier base center apart from the solstics at carrier base center.
Further, said carrier base with a frame connecting structure is: the carrier base outside face is evenly distributed with positioning groove, and the inner of said support just can embed in the positioning groove, and said carrier base and support the inner are welded fixing again.
Further, said roller shaft is a circular arc to outline, and the center of circle of said circular arc overlaps with the carrier base center.
The invention has the advantages that: during use, article along two-way Idler bearing move axially to it on the time owing on the support roller is installed, the roller outside face exceeds support, belongs to friction of rolling between article and the roller, friction force is little, article are prone to the arrival estimating position; Drive roller through the carrier base that rotates again and promote article moving radially along two-way Idler bearing.Roller shaft is a circular arc to outline, and the center of circle of circular arc overlaps with the carrier base center, makes carrier base when rotated, and the axial external surface of roller contacts with article all the time, and area of contact is big, improves friction force, skids when avoiding radially promoting article.
Description of drawings
Fig. 1 is the two-way Idler bearing front view of the present invention.
Fig. 2 is the two-way Idler bearing lateral plan of the present invention.
Fig. 3 is along A-A line section-drawing among Fig. 1.
Fig. 4 is a medium-height trestle structural representation of the present invention.
The specific embodiment
Like Fig. 1,2,3, shown in 4, comprise carrier base 1, support 2, axle 3, roller 4.
Above-mentioned carrier base 1 is an annular, on the outer ring of carrier base 1, is radiativity some supports 2 evenly are installed, and present embodiment medium-height trestle 2 quantity are 8.Carrier base 1 with support 2 connection structures is: carrier base 1 outside face is evenly distributed with positioning groove, and the inner of support 2 just can embed in the positioning groove, and carrier base 1 welds fixing with support 2 the inners again.
The end face of each support 2 all is parallel to the omnibearing line of carrier base 1, and correspondence is drilled with the axle mounting hole between adjacent supports 2 end faces, and the axle mounting hole is perpendicular to the end face of support 2.The axle mounting hole of adjacent stent 2 is stretched at the two ends of axle 3, and roller 4 is installed on axle 3, and the axial outline of roller 4 is a circular arc, and the center of circle of this circular arc overlaps with carrier base 1 center.
The two-way Idler bearing of this kind structure is sleeved on 8 rollers 4 on the axle 3 earlier when assembling, and the two ends with axle 3 penetrate in the axle mounting hole of support 2 again; By 8 supports 2, axle 3, after roller 4 constitutes an annular, the inner with support 2 embeds in the positioning groove of carrier base 1 again, through welding support 2 is connected with carrier base 1 and fixes.
Claims (3)
1. a two-way Idler bearing is characterized in that: comprise the ring support seat, be radiativity on the said carrier base outer ring some supports evenly are installed, be connected with axle between the said adjacent supports end face, on the axle roller is installed; Said roller is higher than distance greater than the solstics distance of cradle top surface apart from the carrier base center apart from the solstics at carrier base center.
2. two-way Idler bearing according to claim 1; It is characterized in that: said carrier base with a frame connecting structure is: the carrier base outside face is evenly distributed with positioning groove; The inner of said support just can embed in the positioning groove, and said carrier base and support the inner are welded fixing again.
