Abstract
The utility model relates to a rotor bearing which is particularly applied in a rotor spinner and belongs to the technical field of textile accessory. The technical project of the utility model is that a rotor is arranged between an outer ring and a spindle and positioned by a retainer, the retainer insulates the rotor, and a scraper seal is arranged in the dust-proof groove of the outer ring, the outer ring is provided with a lipa charging hole which is covered by a lipa charging ring. The utility model is characterized in that the spindle is provided with a channel, the channel and a channel outer circle are together abraded and form into an integral body, and the channel outer circle and a spindle outer circle form into a step. The utility model is compact and reasonable in structure and able to avoid cutting edges resulting from directly abrading the channel outer ring and the spindle outer ring, and simultaneously the channel is protected in the ultraprecision process. Besides, the utility model has the function of storing lipa. When the rotor bearing rotates in a high speed, lipa can be timely supplemented into the channel to reduce friction and abrasion between the rotor, the outer ring and the spindle of the rotor bearing and decrease the vibration noise of the rotor bearing, and lipa can also be used to cool the rotor bearing to prolong the service life of the rotor bearing.
Description
Technical field
The utility model relates to a kind of rotor bearing, specifically is used for rotor spinning machine, belongs to the textile workpiece technical field.
Background technology
At present, the rotor bearing that is used on the rotor spinning machine mainly is made up of outer ring, mandrel, retainer, rolling element (roller or ball), dust ring, centring ring etc.Rolling element (roller or ball) is installed in employing between outer ring and mandrel, with retainer location, even separation roller of retainer and maintenance rolling element proper exercise, dust ring is put in the dustproof groove of outer ring, centring ring plays the role of positioning, and has tank filler sleeve on the outer ring, covers with oiling ring.The mandrel of this kind structure is in mill groove process; groove and mandrel cylindrical junction easily form fast mouthful; and in super smart cylindrical process, can not protect groove; make bearing when running up; easily friction and wearing and tearing of rolling element and cylindrical and mandrel in the bearing; can not effectively reduce bear vibration noise and cooling, influence its service life.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby a kind of rotor bearing is provided, and can avoid cylindrical by direct mill groove and mandrel to form fast mouthful, in super smart process, can protect groove simultaneously, can play the effect of storage grease in addition; Rotor bearing is when running at a high speed, and grease can in time add in the groove, reduces the friction and the wearing and tearing of rolling element and outer ring, mandrel in the rotor bearing, reduction rotor bearing vibration noise and be used for the cooling of rotor bearing.
Main solution of the present utility model is achieved in that
The utility model mainly adopts rolling element (roller or ball) is installed between outer ring and mandrel, and locate with retainer, the even separation roller of retainer, dust ring is put in the dustproof groove of outer ring, have tank filler sleeve on the outer ring, cover with oiling ring, feature is that groove is set on mandrel, groove grinds with the groove cylindrical, and groove cylindrical and mandrel cylindrical form step.
The utility model step degree of depth is: 0.001mm～0.5mm; Width is: 2mm～40mm.
Compared with the prior art the utility model has the following advantages:
The utility model compact conformation, rationally; Can avoid cylindrical by direct mill groove and mandrel to form fast mouthful, in super smart process, can protect groove simultaneously; Rotor bearing is when running at a high speed, and grease can in time add in the groove, reduces the friction and the wearing and tearing of rolling element and outer ring, mandrel in the rotor bearing, and reduction rotor bearing vibration noise and be used for the cooling of rotor bearing prolongs its service life.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model mandrel structural representation.
The specific embodiment
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
The utility model mainly is made up of outer ring 2, mandrel 3, centring ring 4, retainer 5, dust ring 6, rolling element (roller or ball) 7, oiling ring 8, dustproof groove 9, tank filler sleeve 10, groove 11, groove cylindrical 12, mandrel cylindrical 13 and step 14 etc.
The utility model rotor bearing 1 adopts rolling element 7 to connect outer ring 2 and mandrel 3, and with retainer 5 location, keeps the gap and guarantee concentricity.Retainer 5 even separation rollers 7, and keep rolling element 7 proper exercises, improve the bearing internal load and distribute and greasy property; Dust ring 6 is put in the dustproof groove 9 of outer ring 2, has guaranteed not have foreign material to enter bearing inside and has prevented that simultaneously grease from leaking outside; Centring ring 4 plays the role of positioning, and has two tank filler sleeves 10 on the outer ring 2, covers with oiling ring 8, is convenient to the bearing grease of in use can annotating again.Two grooves 11 are set on mandrel 3, and when mill two grooves 11, groove 11 grinds the formation one with groove cylindrical 12, makes groove cylindrical 12 and mandrel cylindrical 13 form a step 14.The degree of depth of step 14 is: 0.001mm～0.5mm; According to two grooves, 11 centre-to-centre spacing length on the mandrel 3, the width of step 14 is that groove cylindrical 12 width are on the mandrel: 2mm～40mm.Fast mouthful of having avoided being formed by direct mill groove 11 and mandrel cylindrical 13 of this design protected groove 11 simultaneously in super smart process, can play the effect of storing grease in addition.Rotor bearing 1 is when running at a high speed, and grease can in time add in two grooves 11, reduces the friction and the wearing and tearing of rolling element 7 and outer ring 2 and mandrel 3 in the rotor bearing 1, reduces the rotor bearing vibration noise and is used for the cooling of rotor bearing, prolongs its service life.
Because rotor bearing 1 is designed to the double channel ball bearing, its rotating speed height, the load of carrying is light, and guarantees its high efficiency with high-precision external form and level and smooth running.This feature is applicable to that BZ1, BZ3, BZ5, BZ6, BZ8, BZ9, BZ10, BZ20 profile shaft hold.
