Abstract
The utility model relates to a bearing provided with a positioning pin structure. The bearing comprises a bearing seat and a bearing positioned in the bearing seat, wherein the bearing is composed of a bearing outer ring, a bearing inner ring, rollers and a retainer, and the bearing outer ring and the bearing seat are in clearance fit; a lap of rollers are arranged between the bearing outer ring and the bearing inner ring, and two feet of the retainer are arranged between the bearing outer ring and the bearing inner ring and are fixed on the rollers; and the bearing outer ring is provided with a positioning pin, and the positioning pin is clamped between the bearing outer ring and the bearing seat. The bearing provided by the utility model has the beneficial effects that the bearing seat on a gear box is generally made of an aluminium product material, the expansion coefficient is two times that of steel, and the bearing outer ring is provided with the positioning pin; and the bearing outer ring is prevented from loop running, the performance of the bearing is improved, and the safety feature is high.
Description
Technical field
The utility model relates to field of bearings, mainly is a kind of bearing that is applied to the band locating pin structure in the gearbox.
Background technique
Tapered roller bearing is widely used in all kinds of mechanical transmissions, and its fit dimension is selected different coordinated schemes such as interference, transition, gap for use according to Environmental Conditions.The bearing that generally is used for gearbox for making the bearing assembling convenient, adopts the bearing outer ring crest clearance to cooperate bearing inner race internal diameter interference fit on this fit dimension usually.But this type of cooperation is prone to make bearing outer ring, fretting occurs, and excessive because of regional temperature contrast, bearing outer ring is cooperated with bearing support excessive gap occurs.
Because bigger gap cooperate to appear in the outer ring, when bearing when the low-grade state of gearbox turns round down, because of outer ring outer radius frictional force less than inner rotating force; And then rotation of outer ring (promptly walking circle) appears; Cause bearing race sliding friction to occur, make the extremely acute rising of bearing temperature, bearing failure occurs.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of above-mentioned existence, and a kind of bearing that prevents away the band locating pin structure that the circle phenomenon takes place is provided.
The purpose of the utility model is accomplished through following technological scheme; It comprises bearing support and is positioned at the bearing of bearing support; Described bearing is made up of bearing outer ring, bearing inner race, roller and retainer; This bearing outer ring and bearing support are Spielpassung, between this bearing outer ring and bearing inner race, are provided with a circle roller; The bipod of described retainer is positioned between bearing outer ring and bearing inner race, and is fixed on the roller.
As preferably, described bearing outer ring is provided with a locating stud, and this locating stud is stuck between bearing outer ring and bearing support.
The beneficial effect of the utility model is: because the bearing support on the gearbox is generally processed with aluminium material; Its expansion coefficient is 2 times of steel, and the locating stud that bearing outer ring is provided with has prevented that the phenomenon of circle from appearring walking in bearing outer ring; Thereby the performance of bearing improves, and Safety performance is high.

Fig. 1 is the structural representation of the utility model.
Fig. 2 is the bearing structure schematic representation of the utility model.
Label in the accompanying drawing is respectively: 1, bearing, 2, bearing support, 3, locating stud, 11, bearing outer ring, 12, bearing inner race, 13, roller, 14, retainer.
Embodiment
To combine accompanying drawing that the utility model is done detailed introduction below: like accompanying drawing 1, shown in 2; The utility model comprises bearing support 2 and is positioned at the bearing 1 of bearing support 2; Described bearing 1 is made up of bearing outer ring 11, bearing inner race 12, roller 13 and retainer 14; This bearing outer ring 11 is Spielpassung with bearing support 2, is provided with a circle roller 13 at this bearing outer ring 11 and 12 of bearing inner races; The bipod of described retainer 14 is positioned at 12 of bearing outer ring 11 and bearing inner races, and is fixed on the roller 13.
Described bearing outer ring 11 is provided with a locating stud 3, and this locating stud 3 is stuck in 2 of bearing outer ring 11 and bearing supports.Because of gearbox is generally processed with aluminium material, its expansion coefficient is 2 times of steel, under hot environment, is prone to make bearing to cooperate pine.To this, design one locating stud (like Fig. 1, shown in 2) on bearing outer ring 11 reaches anti-outer ring and walks to enclose function.
Except that the foregoing description, all employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
