Abstract
The utility model provides a bearing structure of a vibration motor and relates to a vibration motor. Currently, bearing structures inside an end cover in a domestic motor industry are diversified and have respective defects and advantages. The bearing structure cannot have the advantages of simpleness for dismounting, convenience for oil injection, strong integrity and high stability simultaneously. The bearing structure of the vibration motor comprises the end cover provided with a bearing chamber and a bearing arranged in the end cover, and is characterized in that a bearing cover is arranged at the outer side of a bearing; a clamp spring groove is arranged on the end cover at the outer side of the bearing cover; a clamp spring abutted against the bearing cover can be embedded in the clamp groove; an annular oil seal which is in clearance fit with the rotating shaft is arranged in an inner ring of the bearing cover; and an outer ring of the oil seal is in clearance fit with the inner ring of the bearing cover. The bearing structure has good sealing property due to the clearance fit between the annular oil and the bearing cover. The clamp spring for a hole is nested in the end cover, and all the parts inside the end cover are fixed, so that the entire stability of the motor is improved, and the bearing structure is convenient to dismount and mount.
Description
Technical field
The utility model relates to a kind of vibrating motor.
Background technology
At present, the variation of domestic electric machine industry end cap internal bearings structure respectively has drawback and advantage, and bearing arrangement can not take into account simultaneously that dismounting is simple, oiling is convenient, globality is strong, stability is high.
The utility model content
The technical problem that the utility model will solve and the technical assignment of proposition are that the prior art scheme is improved and improved, and a kind of vibrating motor bearing arrangement is provided, and take into account the purpose that dismounting is simple, oiling convenient, globality is strong, stability is high to reach.For this reason, the utility model is taked following technical scheme.
A kind of vibrating motor bearing arrangement; Comprise the end cap of establishing bearing chamber, be located at the bearing in the end cap; It is characterized in that: the outside of bearing is provided with bearing cap, establishes the jump ring groove on the end cap in the bearing cap outside, and the jump ring groove is embedded in the jump ring that can offset with bearing cap; Be provided with in the bearing cap inner ring one with annular oil seal, the outer ring of oil sealing and the bearing cap inner ring matched in clearance of rotating shaft interference fit.Annular oil seal and bearing cap matched in clearance, good airproof performance.Boarding hole is used jump ring on end cap, all inner parts of fixing letter end cap, the resistance to overturning of raising motor, and easy accessibility.
As the further of technique scheme improved and replenish, the utility model also comprises following additional technical feature.
Radial fit gap between the outer ring of oil sealing and the bearing cap inner ring is 0.4-0.6mm.Can prevent that bearing grease from getting into electric machine iron core inside and making motor bearings remain at best running state, improve motor useful life.
Described end cap top is provided with oil filler point, and the bearing locular wall is offered the oil groove that communicates with oil filler point, and the end face that bearing cap and bearing match is provided with the outer ring and oil groove is relative and the inner ring cannelure relative with the bearing roller container cavity.
Described bearing cap comprises concentric location division and sealing, and the race diameter of described sealing is less than the race diameter of location division, and location division and sealing junction form step surface, and the step surface of described jump ring and bearing cap offsets.
Be equipped with the end play of 0.8-2mm between described bearing cap and the bearing and between oil sealing and the bearing.Prevent between motor shaft stuckly, cause that the motor bearings temperature raises, electric machine temperature rise is too high to be burnt out.
Beneficial effect: the dismounting of present technique scheme is simple, oiling convenient, globality is strong, stability is high.
