Abstract
The utility model relates to a rotor bearing for a rotor spinning machine, which belongs to the technical field of textile fitting. The rotor bearing mainly adopts: mounting a rolling body between an outer ring and a spindle, positioning by a retainer, separating the rolling body by the retainer, putting a dustproof ring into a dustproof groove, providing an oil adding hole on the outer ring, covering by a oil adding loop, and arranging a groove on the spindle, wherein the groove and an outer excircle of the groove are together worn to form an integration, and the outer excircle of the groove and the spindle form a step. The utility model has the compact and reasonable structure, can avoid the shape edge formed by a direct grinding groove and the exicrcle of the spindle, and can protect the groove during superfinishing process at the same time, in addition, the utility model can play the function of storing grease, when the rotor bearing runs with high speed, the grease can in time supplement to the groove, thus reducing the friction and wearing between the rolling body in the rotor bearing and cooling the rotor bearing, and prolonging the service life thereof.
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 provides a kind of rotor bearing that is used for rotor spinning machine, 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.
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, has tank filler sleeve on the outer ring, covers 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, and the step degree of depth is: 0.001mm～0.5mm; Width is: 2mm～40mm.
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.

Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model mandrel structural representation.
The specific embodiment
The utility model structure is as shown in Figure 1 and Figure 2: a kind of rotor bearing that is used for rotor spinning machine, adopt rolling element 7 to connect outer ring 2 and mandrels 3, and with retainer 5 location, keep gap and assurance 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.
