Abstract
The invention discloses a resin bearing for a roller. Two ends of a bearing periphery are covered with a roller cylinder barrel; and the bearing comprises an inner ring, an outer ring, a ball and a maintenance rack. The ball is arranged on the maintenance rack; the maintenance rack is arranged between the inner ring and the outer ring; and an outer ring end face is cooperated with an outer bearing cap. A tooth form cooperation between the outer ring and the bearing cap endows a good sealing performance on the bearing; a ledge is arranged on the outer ring and forms an axial fixity with other components during installation and cooperation, so as to save costs; an axial-directional side of the bearing inner ring is outwardly protruded from the bearing cap, so as to play a role of axial fixity; an integral structure design can reduce working noise and wearing of the bearing and prolong a usage life of the bearing. In addition, the bearing has advantages of excellent contamination resistant and corrosion resistant resin material, simple integral structure, easy moulding and processing, and prolonged usage life.
Description
Technical field
The present invention relates to the component of machine apparatus field, relate in particular to a kind of cylinder resin bearing.
Background technique
The major function that bearing is is supporting rotating shaft or other moving body, and guiding rotation or moving movement also bears by axle or parts on shaft transmission and the load of coming.Especially cylinder bearing, it is subjected to radial and axial bearing capacity all bigger, each accessory replaceability is strong, more and more be applied in the various logistics equipment system, because volume is less, simplifies mounting structure, thereby reduced manufacture cost, and compact structure is various, various in style, applicability wide, be easy to installation, can be widely used in machinery and process lines such as various lathes, metallurgical machinery, textile manufacturing machine, printing machinery.
Cylinder of the prior art is generally the standard piece bearing with bearing, substantially form by inner ring, outer ring, rolling element, retainer and bearing washer, bearing washer plays fixation to several parts of bearing, can also seal rolling element, but there is following shortcoming in this bearing:
When (1) bearing runs up,, produce wearing and tearing, easily cause damage of bearings because the friction between each component can increase energy consumption, even serious meeting damage machine, the noise that has formed when having strengthened bearing operation has more reduced bearing life.
(2) have high vacuum when running into, hot irradiation, high temperature and ultralow temperature, Korrosionsmedium and when meeting working condition such as oily poisoning medium easily, the easily oxidized and corrosion of bearing has influenced the usability and the bearing life of product.
Summary of the invention
The applicant is big at above-mentioned existing noise, sealing is poor, shortcomings such as perishable oxidation, provide a kind of rational in infrastructure, easily manufactured cylinder resin bearing, it has good anti fouling performance and anticorrosive property, thereby has simplified bearing structure, improve the sealing of bearing, reduced the noise situation that produces when bearing runs up.
The technical solution adopted in the present invention is as follows:
A kind of cylinder resin bearing, bearing outside diameter two ends pack roller entire body comprises inner ring, the outer ring, ball, retainer, ball are arranged on the retainer, and retainer is arranged between inner ring and the outer ring, and cycle surface cooperates with outer end bearing cover.
It is further characterized in that:
The outer ring is provided with shoulder, described circular bead surface and roller tube end face butt.
Beneficial effect of the present invention
Cooperate with the bearing cap profile of tooth by the outer ring, thereby have the better seal performance; The outer ring is provided with shoulder, installs when cooperating, and has formed axial restraint with other component, saves cost; And the axial side size evagination of bearing inner race is somebody's turn to do in bearing, has the effect of axial restraint; All-in-one-piece structural design makes bearing reduce noise in the course of the work, has reduced wearing and tearing, has improved the working life of bearing.Adopt resin material to have good anti fouling performance and anticorrosive property, overall structure is simple, and shaping operation is easy, has improved the working life of bearing.
Description of drawings
Fig. 1 is an installment state schematic representation of the present invention.
Fig. 2 is a structural representation of the present invention.
Fig. 3 is the three-dimensional erection drawing of retainer.
Fig. 4 is the enlarged view of A portion among Fig. 2.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
Cylinder of the present invention is contracted with resin shaft and is drawn together cylinder 1, ball 3 is embedded in the U type groove that distributes on the retainer 7, and ball 3 adopts stainless steel, and retainer 7 is arranged between inner ring 5 and the outer ring 2, inner ring 5 axial side size evaginations of bearing have the axially locating effect in bearing cap 6.The periphery of outer ring 2 is enclosed with the cylindrical shell of cylinder 1, have shoulder 4 on the outer ring 2, during assembling and the body end surface butt of cylinder 1, make the cylinder axially locating reliable, the end face of outer ring 2 cooperates with outer end bearing cover 6 profiles of tooth, as shown in Figure 4, the profile of tooth cooperation makes and is connected between the parts closely, has the better seal performance, prevents that effectively dust and granular etc. from entering, avoided the installation difficulty of prior art middle (center) bearing packing ring, the defective of sealing effect difference has reduced friction, has reduced noise, make bearing working steady, life-saving.Remaining part all adopts resin material except that ball 3, and it is particularly suitable for having high vacuum at the bottom of having excellent self lubricity, wear resistance, friction factor, hot irradiation, high temperature and ultralow temperature, Korrosionsmedium and meet operating mode such as oily poisoning medium easily.
More than describing is explanation of the invention, is not that institute of the present invention restricted portion is referring to claim to the qualification of invention, and under the situation of spirit of the present invention, the present invention can do any type of modification.
Claims (2)
1. cylinder resin bearing, bearing outside diameter two ends pack roller entire body comprises inner ring, the outer ring, ball, retainer is characterized in that: ball is arranged on the retainer, and retainer is arranged between inner ring and the outer ring, and cycle surface cooperates with outer end bearing cover.
2. cylinder resin bearing as claimed in claim 1, it is characterized in that: described outer ring is provided with shoulder, described circular bead surface and roller tube end face butt.
