Abstract
The utility model relates to a rotating cup bearing which mainly comprises an outer ring, a core shaft, an oiling ring, a retaining rack, a dustproof ring and a rolling body. The rolling body is arranged between the outer ring and the core shaft, the retaining rack is separated from the rolling body, the dustproof ring and a concave-shaped dustproof ring are arranged in a dustproof groove of the outer ring, and an oiling hole which is arranged on the outer ring is covered by the oiling ring. The rotating cup bearing has the characteristics that a trapezoid groove and a positioning groove are arranged on the inner diameter of the outer ring, and an oil distributing ring is then embedded. The structure of the rotating cup bearing is simple, compact and reasonable; the rotating cup bearing avoids unbalanced lubrication caused by non-uniform oiling, leads over-high partial temperature and can exert the function of storing oil; therefore, the oil needed by the bearing when in work can be continuously provided, so as to lead a channel to maintain the lubricating effect for a longer time, thereby prolonging the service life of the bearing. The uniform distribution of the oil can effectively lower noise and improve the working environment of workers; under the working state, the internal temperature of the bearing can be balanced and the working precision can be improved.
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 oiling structure of this kind bearing is after adding oil, can not well disperse grease, it is inhomogeneous that two raceway grooves are refueled, the raceway groove lubricant effect is inconsistent, and the channel temperature of lubricant effect deficiency is understood the too early rated temperature that surpasses, and it is overheated that bearing is produced, precision step-down not only, it is big that noise becomes, and very quick-wearing lost efficacy, and reduce service life greatly.
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 the lubricated imbalance that causes owing to fatten is inhomogeneous, makes the bearing local temperature too high; Can play the effect of storage grease, make the maintenance lubricant effect that raceway groove can be more permanent, thereby can prolong the service life of bearing.
The technical scheme that provides according to the utility model, rotor bearing comprises outer ring, mandrel, oiling ring, retainer, dust ring, rolling element, employing is installed rolling element between outer ring and mandrel, the retainer separation roller, dust ring and spill dust ring are put in the dustproof groove of outer ring, have tank filler sleeve on the outer ring, cover with oiling ring, feature is: dovetail groove and locating slot are set on the internal diameter of outer ring, put into oil distributing ring again.
The degree of depth of described dovetail groove is: 0.01mm～3mm; Width is: 1mm～10mm.
The length range of described outer ring is: 56mm～61mm; Outside diameter of mandrel's scope is: Φ 8.9mm～Φ 10mm.
Compared with the prior art the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; Avoided the lubricated imbalance that causes owing to fatten is inhomogeneous, make the bearing local temperature too high, can also play the effect of storage grease, required when constantly supplying bearing working, make the maintenance lubricant effect that raceway groove can be more permanent, thereby prolonged the service life of bearing; Grease is evenly distributed and can effectively reduces noise, improves the working environment of workers; Can also balanced bearing internal temperature in working order, improve operating accuracy.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model outer ring structure schematic diagram.
The specific embodiment
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
As Fig. 1～shown in Figure 2, comprising: rotor bearing 1, outer ring 2, mandrel 3, oiling ring 4, retainer 5, dust ring 6, oil distributing ring 7, spill dust ring 8, pad 9, rolling element (roller or ball) 10, dustproof groove 11, tank filler sleeve 12, dovetail groove 13, dovetail groove chamfering 14, outer ring internal diameter 15, locating slot 16 and locating slot chamfering 17 etc.
The utility model rotor bearing 1 adopts rolling element 10 to connect outer ring 2 and mandrel 3, and with retainer 5 location, keeps the gap and guarantee concentricity.Retainer 5 even separation rollers 10, and keep rolling element 10 steady in a long-term to turn round, card is put spill dust ring 8 and two pads 9 in the dustproof groove 11 of outer ring 2, and outermost layer is with dust ring 6 sealings, the effective like this leakage that has stoped grease may occur in running up.On the external diameter of outer ring 2, offer a groove that is used to place oiling ring 4, on the internal diameter of outer ring 2, then offer a dovetail groove 13 and locating slot 16.Dovetail groove 13 both sides are provided with dovetail groove chamfering 14, and locating slot 16 1 ends are provided with locating slot chamfering 17.16 of dovetail groove 13 and locating slots are to lubricate inhomogeneous and raceway groove superheating phenomenon that cause in order to put into oil distributing ring 7 on the position accordingly, to guarantee evenly to disperse the grease of adding from tank filler sleeve 12, preventing.Described dovetail groove 13 degree of depth are: 0.6mm, width is: 7mm.The length range of described outer ring is: 56mm; Outside diameter of mandrel's 19 scopes are: 4 of Φ 10mm. oiling rings are for when not needing to annotate grease, close tank filler sleeve 12.Rotor bearing 1 is when running at a high speed, grease can in time add in the dovetail groove 13, played the effect that stores grease, and can reduce the friction and the wearing and tearing of rolling element in the rotor bearing 1 10 and outer ring 2 and mandrel 3, reduce the rotor bearing vibration noise and be used for the cooling of rotor bearing, prolong its service life.
Because rotor bearing 1 is designed to the double channel ball bearing, and has controllability on the size of outer ring and oil distributing ring, and is widely applicable, adds its rotating speed height, the load of carrying is light, and high-precision external form and level and smooth running guarantee its high efficiency.Therefore, this feature is applicable to that profile shafts such as BZ8C, BZ1O hold.
