Abstract
The utility model discloses a track and needle roller bearing, aiming at providing a bearing with difficulty in sliding and high stability. A roller path is arranged between an inner ring and an outer ring, a roller is positioned in the roller path, a retainer ring props against one side of the inner ring, the inner diameter of the retainer ring is equal to that of the inner ring, the retainer ring is in threaded fixation with the outer ring, the combination position of the other side of the inner ring and the outer ring serves as a connecting part, the outer ring and the inner ring inside the connecting part are both provided with clamping grooves, and a clamp spring is arranged in each clamping groove. The retainer ring of the track and needle roller bearing can prevent the inner ring propping against the retainer ring from moving towards the retainer ring, the inner diameter of the retainer ring is as the same as that of the inner ring, so that the retainer ring and the inner ring can be assembled on the bearing simultaneously, and radial deflection is prevented; furthermore, the other side of the inner ring and the outer ring are fixed by the clamp spring, therefore, the axial sliding and shifting of the inner ring relative to the outer ring can be effectively prevented, and the stability of the installation of the inner ring is improved; the retainer ring and the outer ring are in threaded fixation, so that the assembling and disassembling operations are convenient.
Description
Technical field
The utility model relates to a kind of bearing, and more particularly, it relates to a kind of outer ring and roll assembly.
Background technique
Bearing is to work the parts of fixing and reducing the load friction factor in mechanical transmission course.Also can say, when other parts produce relative movement each other on axle, be used for reducing the fixing parts of friction factor and retainer shaft central position in power transmission process.Bearing is a kind of very important component in contemporary machinery.Its major function is the supported mechanical solid of rotation, the mechanical load friction factor in order to reduction equipment in transmission process.Shakiness or sliding phenomenon easily appear installing in bearing inner ring in the process of installing, and easily skew to a certain degree occurs, and existing bearing inconvenience dismounting, are unfavorable for maintenance.
The model utility content
The deficiency existed for prior art, the purpose of this utility model is to provide a kind of not being prone to slide and the high bearing of stability.
A kind of outer ring and roll assembly, comprise inner ring, outer ring and roller, be provided with raceway between described inner ring and outer ring, described roller is placed in raceway, and described inner ring one side is conflicted and is provided with back-up ring, and described back-up ring equates with the inner ring internal diameter and be coaxial, described back-up ring and outer ring screw thread are fixed, the junction of described inner ring opposite side and outer ring is joint, and described joint outer ring and inner ring are equipped with draw-in groove, in described draw-in groove, is provided with jump ring.
Described inner ring is provided with through hole, and described through hole is communicated with raceway.
Be provided with a plurality of oil storage tanks in described raceway.
On described outer ring, edge is provided with chamfering.
By adopting technique scheme, the back-up ring that this outer ring and roll assembly is provided with, can prevent that the inner ring of conflicting with this back-up ring is to this side shifting, the back-up ring internal diameter is identical with the inner ring internal diameter, can be assemblied on bearing simultaneously, prevent radial deflection, and the opposite side of inner ring and outer ring are fixed with jump ring, can effectively prevent that the relative outer ring of inner ring from endwisely slipping, being offset, improve the stability that inner ring is installed.And back-up ring and outer ring fix with screw thread, facilitate installation and removal.
The accompanying drawing explanation
The structure sectional view that Fig. 1 is the utility model embodiment outer ring and roll assembly.
The zoomed-in view that Fig. 2 is joint 6 in Fig. 1.
Reference character in figure: 1, inner ring; 2, outer ring; 3, roller; 4, raceway; 41, oil storage tank; 5, back-up ring; 6, joint; 61, draw-in groove; 7, jump ring; 8, through hole.
Embodiment
See figures.1.and.2 the utility model embodiment is described further.
A kind of outer ring and roll assembly, comprise inner ring 1, outer ring 2 and roller 3, be provided with raceway 4 between described inner ring 1 and outer ring 2, described roller 3 is placed in raceway 4, and described inner ring 1 one sides are conflicted and are provided with back-up ring 5, and described back-up ring 5 internal diameters equate with inner ring 1 internal diameter, described back-up ring 5 is fixed with outer ring 2 use screw threads, the junction of described inner ring 1 opposite side and outer ring 2 is joint 6, and described joint 6 Internal and external cycles 2 are equipped with draw-in groove 61 with inner ring 1, in described draw-in groove 61, are provided with jump ring 7.The back-up ring 5 that this outer ring and roll assembly is provided with, can prevent that the inner ring 1 of conflicting with this back-up ring 5 is to this side shifting, back-up ring 5 internal diameters are identical with inner ring 1 internal diameter, can be assemblied on bearing simultaneously, prevent radial deflection, and the opposite side of inner ring 1 and outer ring 2 use jump rings 7 are fixing, can effectively prevent that the relative outer ring 2 of inner ring 1 from endwisely slipping, being offset, and have improved the stability that inner ring 1 is installed.And back-up ring 5 fixes with outer ring 2 use screw threads, facilitate installation and removal.
Described inner ring is provided with through hole 8, and described through hole 8 is communicated with raceway 4.When maintenance service, oiling agent can be injected in raceway 4 by described through hole 8, to guarantee the lubricity of raceway 4
Be provided with a plurality of oil storage tanks 41 in described raceway 4.Oil storage tank 41 can be alleviated the impact force of roller 3, also can store a small amount of oiling agent, guarantees the lubricity of roller 3.
On described outer ring 2, edge is provided with chamfering 21.The chamfering 21 that outer ring 2 is provided with is convenient to this bearing is placed on working equipment.
