Abstract
The utility model relates to a clamping roller bearing. The clamping roller bearing comprises a mandrel and a screw sleeve, wherein both ends of the mandrel are respectively provided with a spindle spinning bearing and a bearing, a spring is arranged between the spindle spinning bearing and the bearing, and the spindle spinning bearing, the bearing and the spring are together arranged in the screw sleeve; one end of the mandrel is provided with an oil injection hole, and the oil injection hole is provided with an oil discharge hole perpendicular to the oil injection hole; one end of the screw sleeve is connected with an injection-moulding oil cup through screw threads, and the oil inlet of the injection-moulding oil cup is butted with the oil injection hole. The utility model is reasonable in structure; according to the utility model, the oil injection hole is arranged on the mandrel, oil can conveniently enter an oil filling port of the mandrel through the injection-moulding oil cup by adopting an oil gun and then flows into the bearing in the practical using process so that a channel and a rolling body can be lubricated in time when the bearing revolves, and therefore, the friction and the abrasion are reduced; meanwhile, the oil can lower the noises of the bearing and be used for the heat dissipation and the cooling of the bearing, and therefore, the service life of the bearing can be prolonged; and the leakage of oil can be stopped and the oil can be conveniently injected by utilizing the injection-moulding oil cup; and in addition, the utility model has convenience for use and lowered cost.
Description
Technical field
The utility model relates to the textile workpiece technical field, in particular for a kind of pinch roller bearing on the rotor spinning machine.
Background technology
At present, be used for the pinch roller bearing on the rotor spinning machine, comprise mandrel, swivel nut, said mandrel two ends are installed respectively and are spun split bearing and bearing, saidly spin the mounting spring between bearing and the bearing of splitting, and together are installed in the swivel nut; Said bearing comprises rolling element (roller or ball), outer ring, retainer, and rolling element (roller or ball) is installed between said outer ring and the mandrel, and with the retainer location, retainer separation roller and maintenance rolling element proper exercise; The internal face butt of the outer ring of said bearing and swivel nut one end, and fix through back-up ring at bearing one end, on the said swivel nut excircle blind nut is installed; A said end that spins the bearing that splits is fixed through the openend of cover plate and swivel nut.It is simple in structure, makes with easy for installation, but in actual use; When bearing needs fatten, need blind nut be dismantled, utilize oil syringe to add grease at the bearing place then; Grease is more difficult to get access inner to bearing, and the grease of adding can not be fed directly to bearing inside, so during bearing operation; Can not in time lubricate raceway groove and rolling element; Can't effectively reduce friction and wear and tear, can not effectively reduce bearing noise simultaneously and be used for the heat radiation and the cooling of bearing, thereby shorten the service life of bearing.
The utility model content
The applicant is to above-mentioned prior art middle (center) bearing oiling trouble, and shortcomings such as lubricant effect difference provide a kind of rational in infrastructure; Easy to operate pinch roller bearing can in time be lubricated bearing, reduces friction and wear and tear; Simultaneously can reduce bearing noise, prolong its service life.
The technical scheme that the utility model adopted is following:
A kind of pinch roller bearing comprises mandrel, swivel nut; Said mandrel two ends are installed respectively and are spun split bearing and bearing, saidly spin the mounting spring between bearing and the bearing of splitting, and together are installed in the swivel nut; Said mandrel one end has oil filler point, on said oil filler point, also has vertical with it oil outlet; Said swivel nut one end is through the forced filling oil cup that is threaded, and the oil-in of said forced filling oil cup docks with oil filler point.
Its further technical scheme is:
The diameter of said oil filler point is 0.5mm～7mm.
The beneficial effect of the utility model is following:
The utility model is rational in infrastructure, through oil filler point is set on mandrel, in the actual use; Grease can adopt oil gun to flow into bearing inside behind the tank filler sleeve through forced filling oil cup entering mandrel easily; When bearing operation, can in time lubricate raceway groove and rolling element, reduce friction and wear and tear; While can be reduced bearing noise and is used for heat radiation, the cooling of bearing, can prolong its service life; Utilize forced filling oil cup both can to leak by the block grease, also be convenient to oiling, easy to use, reduce cost.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the structural representation of the utility model mandrel.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the utility model is described.
As shown in Figure 1, the described pinch roller bearing of the utility model comprises mandrel 1, swivel nut 5; Mandrel 1 two ends are installed respectively and are spun split bearing 4 and bearing; Spin the mounting spring 11 between bearing 4 and the bearing of splitting, and together be installed in the swivel nut 5, mandrel 1 one ends have oil filler point 1-2; Its diameter is 0.5mm～7mm, on oil filler point 1-2, also has vertical with it oil outlet 1-3; Swivel nut 5 one ends are through the forced filling oil cup 10 that is threaded, and the oil-in of forced filling oil cup 10 docks with oil filler point 1-2.
In the actual installation process, bearing is installed, ball 8 is installed between the raceway groove 1-1 of outer ring 7 and mandrel 1, and with retainer 9 location, the size of retainer 9 and quantity are confirmed according to the diameter of axle of mandrel 1 at an end of the mandrel 1 that is processed with oil filler point 1-2 and raceway groove 1-1; Link to each other through spring 11 and spinning of the other end bearing 4 that splits then; With its integral installation in swivel nut 5, the internal face of swivel nut 5 respectively with the outer ring butt of bearing, be positioned at swivel nut 5 openends 2 places and cover plate 3 be placed on the outer end of spinning the bearing 4 that splits; Preventing to spin the bearing 4 that splits moves axially; And push down cover plate 3 through the opening crimping, it is inner to have guaranteed not have foreign material to get into bearing simultaneously, prevents that simultaneously grease from leaking outside; The other end that is positioned at swivel nut 5 screws in forced filling oil cup 10 through being threaded; Can be connected with other parts through nut 6 on swivel nut 5 excircles.Be the utility model simple installation, cost is low.
The oiling mode of the utility model is to utilize forced filling oil cup 10 pouring-in oilings.When in use needing fatten, grease can inject forced filling oil cup 10 with oil gun, and the oil-in through forced filling oil cup 10 enters in the oil filler point 1-2 of mandrel 1 then; Thereby enter into raceway groove 1-1 from oil-out 1-3 outflow; Get into bearing inside then, can in time lubricate raceway groove 1-1 and roller 8, effectively reduce the friction and wear of bearing; Needing in the prior art to have avoided the troublesome operations of oiling behind the dismounting blind nut; The utility model can reduce bearing noise simultaneously and be used for the heat radiation of bearing, and cooling prolongs its service life.On the other hand, directly adopt forced filling oil cup 10 block greases to leak, be convenient to oiling again, reduced cost.
More than describing is the explanation to the utility model, is not the qualification to utility model, and the utility model institute restricted portion within the protection domain of the utility model, can be done any type of modification referring to claim.
