Abstract
The utility model relates to a rotor bearing, in particular to a rotor bearing used for a rotor spinning machine, belonging to the technical field of spinning accessories. The rotor bearing mainly comprises an outer ring, a mandrel, a maintaining frame, a dustproof ring and a roller or a roll ball, wherein the roller or the roll ball is connected with the outer ring and the mandrel and positioned by the maintaining frame to maintain a gap and guarantee the concentricity; the dustproof ring and an O-shaped ring are put in a dustproof groove of the outer ring; and an oil filling hole is arranged on the outer ring and covered with an oil filling cover. The rotor bearing is characterized in that first gradient layers respectively seep on the inner surface and the outer surface of the outer ring, and second gradient layers respectively seep on the surface of the mandrel. Because the lubricating abrasion resistant gradient layers are respectively arranged on the surfaces of the outer ring and the mandrel of the bearing with a processed groove, the surfaces of the outer ring and the mandrel have lubricating abrasion resistance, and the core part can keep inherent obdurability so as to reduce the surface friction coefficient, improve the combination property of the bearing and prolong the service life of the bearing in multiples.
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
In prior art, 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 outer ring of this kind bearing and the surface of mandrel can enter one and wear and tear the phase rapidly after use after a while, and it is big that precise decreasing, noise become, and rotate instability and cause the surface to produce overheated and burn inefficacy, reduce service life.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby provide a kind of and be respectively equipped with the lubricating and wear-resisting gradient layer at bearing outer ring that processes groove and mandrel surface, can make outer ring and mandrel surface have lubricating and wear-resisting, heart portion keeps intrinsic obdurability, thereby can reduce skin-friction coefficient, improve the bearings synthesis performance, prolong the bearing rotor bearing in service life at double.
The technical scheme that provides according to the utility model, a kind of rotor bearing comprises outer ring, mandrel, retainer, dust ring, roller or ball, described roller or ball connect outer ring and mandrel, and with the retainer location, keep the gap and guarantee concentricity, dust ring and O type circle are put in the dustproof groove of outer ring, have tank filler sleeve on the outer ring, cover with oiling ring, feature is: described outer ring surfaces externally and internally is impregnated with first gradient layer respectively, and the surfaces externally and internally of described mandrel is impregnated with second gradient layer respectively.
The thickness of described first gradient layer and second gradient layer is: 0.001mm～3mm.
Compared with the prior art the utility model has the following advantages:
The utility model compact conformation, technology are reasonable; Avoided because working speed height, working environment requirement are special the anti-wear performance of material itself and cause the too early wear out failure of bearing.Owing to adopt low-temperature ion to infiltrate, can generate the sulfide about 100 microns and the gradient layer of oxide, make the surface have lubricating and wear-resisting, can protect bearing channel to a great extent and strengthen anti-wear performance, it is too high to prevent to heat up.For relatively rotating between mandrel and the outer ring, surface abrasion resistance then more is provided, reduce skin-friction coefficient, make more permanent maintenance stability of rotation, thereby prolonged the service life of bearing at double.
Description of drawings
Fig. 1 is the utility model 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:
As shown in Figure 1: comprise outer ring 2, mandrel 3, oiling ring 4, retainer 5, dust ring 6, O type circle 7, tank filler sleeve 8, packing ring 9, rolling element (roller or ball) 10, dustproof groove 11, first gradient layer 12 and second gradient layer 13.
The utility model rotor bearing 1 adopts rolling element (roller or ball) 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 (roller or ball) 10, and keep rolling element (roller or ball) 10 proper exercises, improve the bearing internal load and distribute and greasy property; Dust ring 6 and O type circle 7 are put in the dustproof groove 11 of outer ring 2, have guaranteed not have foreign material to enter bearing inside and have prevented that simultaneously grease from leaking outside; Have tank filler sleeve 8 on the outer ring 2, cover, be convenient to the bearing grease of in use can annotating again with oiling ring 4.The surfaces externally and internally of outer ring 2 and mandrel 3 carries out the technical finesse of LGM lubricating and wear-resisting respectively, adopt low-temperature ion to infiltrate on the surface, can generate first gradient layer 12 of sulfide and oxide and the thickness of second gradient layer, 13, the first gradient layers 12 and second gradient layer 13 is: 0.1mm; Can keep simultaneously the hardness of material, surface roughness does not change, and the heart portion of material keeps intrinsic obdurability, thereby reduces skin-friction coefficient.Rotor bearing 1 is in long-term running at a high speed, and grease can in time add in two raceway grooves, the friction and the wearing and tearing of rolling element (roller or ball) 10 and outer ring 2 and mandrel 3 in the minimizing rotor bearing 1; Add the new treatment process of outer ring 2 and mandrel 3, make its ABRASION RESISTANCE and lubricated on all be greatly improved and improve, can reduce the rotor bearing vibration noise and accelerate the cooling of rotor bearing, prolong its service life at double.
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 profile shafts such as BZ1, BZ3, BZ5, BZ6, BZ8, BZ9, BZ10, BZ11 hold.
