Abstract
The utility model relates to a rolling needle bearing with a plastic space ring, which is provided with an outer ring; the outer ring is internally pressed with a retainer, a rolling needle, a sealing ring and the plastic space ring; the plastic space ring is positioned at the outer side of the sealing ring; the outer ring is provided with a rolling edge at the outer side of the plastic space ring; the sealing ring and the inner wall of the outer ring are in interference fit; the plastic space ring and the inner wall of the outer ring are in interference fit or clearance fit; the plastic space ring is a ring-shaped ring formed by engineering plastics through one-time processing of an injection molding technique; one side of the inner wall of the plastic space ring, facing to a curled edge, is provided with a chamfer for guiding shaft assembly; a chamfer flaring is outward; and the outer wall of the plastic space ring is provided with a step gap for preventing the curled edge of the outer ring from generating interference to the plastic space ring. As the plastic space ring is added at the outer side of the sealing ring, the rolling needle bearing can protect the sealing ring from being directly impacted by shafts, and guide the shaft assembly, thus guaranteeing the sealing performance of the sealing ring and prolonging the service life.
Description
Technical field
The utility model relates to technical field of bearings, especially relates to a kind of needle bearing with the plastics spacer ring.
Background technique
Adopt the bearing of drawn cup for some, seal ring is installed in the retainer outside, seal ring is outer without any guiding device, therefore, and in assembly process, when axle is installed into bearing without any the guiding measure, forbidden and the lip of bump seal ring because of leading easily in the axle assembly process, the seal ring of especially big lip or lips mouth causes that easily the seal ring lip breaks, influence the sealability of seal ring, thereby cause bearing failure.
The model utility content
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art; a kind of needle bearing with the plastics spacer ring is provided, makes axle have guide function to axle when assembling, the protection seal ring is not damaged; guarantee the sealability of seal ring, prolong the working life of bearing.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of needle bearing with the plastics spacer ring, described bearing has the outer ring that punching press forms, be pressed with retainer, needle roller, seal ring, plastics spacer ring in the outer ring successively, the plastics spacer ring is positioned at the outside of seal ring.
Further, described seal ring is the lips mouth sealing ring, and described outer ring inwall has step, and seal ring and outer ring inwall interference fit can prevent the seal ring axial float like this.
Further, described outer ring inwall has step, and described plastics spacer ring and outer ring inwall interference fit or Spielpassung can prevent plastics spacer ring axial float.
Further, described plastics spacer ring is the annular ring that is formed through the Shooting Technique time processing by engineering plastics, so the making of plastics spacer ring is simple, and cost is lower.
Further, described plastics spacer ring inwall has the chamfering that is used for the leading axle assembling towards crimping one side, and the chamfering enlarging is outside.Therefore, in assembly process, the installation of bootable axle; the lip bump seal ring as the seal ring of big lip or lips mouth, can protect the seal ring lip not broken by the axle bump because lead inaccurate to prevent axle; guarantee the sealability of seal ring, and then prolong the working life of bearing.
Further, described outer ring has crimping in the plastics spacer ring outside, and described plastics spacer ring outer wall has the crimping that prevents the outer ring and the plastics spacer ring produced the step breach of interfering.Like this, can prevent in the crimping process the interference of the inwall fillet that produces because of crimping, can not influence the flexibility of bearing, and can effectively prevent the generation of plastic flash the plastics spacer ring.
The beneficial effects of the utility model are: in sum; the utility model has installed the plastics spacer ring additional in the seal ring outside; can protect seal ring not to be subjected to the direct bump of axle; and the plastics spacer ring has the outside chamfering of enlarging; the assembling of bootable axle; also further protect seal ring not to be subjected to the bump of axle, thereby guaranteed the sealability of seal ring, prolonged the working life of bearing.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of outer ring in the utility model;
Fig. 3 is the structural representation of plastics spacer ring in the utility model;
Wherein: 1. outer ring, 2. retainer, 3. needle roller, 4. seal ring, 5. plastics spacer ring, 6. crimping.
Embodiment
Needle bearing as Fig. 1 Fig. 2 band plastics spacer ring shown in Figure 3, has the outer ring 1 that punching press forms, be pressed with retainer 2 in the outer ring 1 successively, be installed in needle roller 3, seal ring 4, plastics spacer ring 5 in the retainer 2, plastics spacer ring 5 is positioned at the outside of seal ring 4, and outer ring 1 has crimping 6 in plastics spacer ring 5 outsides.Seal ring 4 is the lips mouth sealing ring, and outer ring 1 inwall has step, seal ring 4 and outer ring 1 inwall interference fit.Plastics spacer ring 5 and outer ring 1 inwall interference fit.
As shown in Figure 3, plastics spacer ring 5 is the annular ring that is formed through the Shooting Technique time processing by engineering plastics.Plastics spacer ring 5 inwalls have the chamfering that is used for the leading axle assembling towards crimping 6 one sides, and the chamfering enlarging is outside.Plastics spacer ring 5 outer walls have the 6 pairs of plastics spacer rings of crimping 5 that prevent outer ring 1 and produce the step breach of interfering.
The utility model has installed plastics spacer ring 5 additional in seal ring 4 outsides; can protect seal ring 4 not to be subjected to the direct bump of axle; and plastics spacer ring 5 has the outside chamfering of enlarging; the assembling of bootable axle; also further protected seal ring 4 not to be subjected to the bump of axle; thereby guarantee the sealability of seal ring 4, prolong the working life of bearing.
