Description
Technical field
The utility model relates to a kind of pulley, the quiet pulley that particularly a kind of energy waterproof noise control used on guide bead is dust-proof.
Background technique
The wheeling support both sides of existing curtain rail are equipped with a pair pulley, the manufacture of pulley generally selects plastics to be raw material, by the technique once-through of plastic mould injection moulding, mounting hole is provided with in the middle of skidding, the both sides that two-wheeled is fixed on by rivet, after this kind of pulley uses a period of time, due to rivet or pulley distortion, when hanging with the sliding in guide rail of curtain, between plastic pulley and metal guide rail, just there is the slip sound that generation is larger.For overcoming above-mentioned existing problems, also have the pulley at metal bearing outsourcing plastics, but due to the plastics of molding and forming comparatively hard, when sliding in guide rail, still can send larger sound, in addition, bearing also can not be able to use because of leakage of oil, water inlet and dust fall.
Summary of the invention
The purpose of this utility model is the problems referred to above existed for existing curtain roller, provides one in use can effectively reduce noise, movable quiet pulley freely.
The technological scheme that the utility model solves the problems of the technologies described above and adopts is: a kind of quiet pulley, comprises bearing unit, plastics centre circle, flexible glue outer ring; Described bearing unit comprises bearing outer ring, bearing inner race, retainer, rolling element and dust cover, described retainer is located between bearing outer ring and bearing inner race, described rolling element is located on retainer, described rolling element occurs to roll and then drive retainer to rotate, in running clearance between described retainer and bearing outer ring, bearing inner race and and rolling element between rolling gap in be all filled with oiling agent, it is characterized in that: the both sides at described bearing outer ring and bearing inner race edge are provided with draw-in groove, dust cover is fastened in this draw-in groove.
As improvement, the outer surface of described bearing outer ring is provided with groove circumferentially.
As improvement, described rolling element is steel ball, is made up of GCr15 steel.
As improvement, described bearing outer ring and bearing inner race are made by GCr15 steel, the madial wall of described bearing outer ring is provided with the rolling surface for rolling element running, the outer side wall of described bearing inner race is provided with the rolling surface for rolling element running, and the gap between described rolling surface and rolling element is 0.0013-0.002mm.
As improvement, described oiling agent is lubricant oil or lubricating grease, and filling out fat amount is 0.12-0.18g.
As improvement, described bearing unit outer wrapping plastics centre circle, plastics centre circle outer wrapping flexible glue outer ring is once shaping on injection machine completes; Described plastics centre circle is made up of PTFE material; Described flexible glue outer ring is made up of PV material.
Compared with prior art, the utility model has the advantage of: adopt technique scheme, the quiet pulley of the utility model, is formed by bearing, plastics, flexible glue triplicity, the outer surface of bearing outer ring is provided with groove circumferentially, adds the combination force of plastics and bearing; Bearing unit outer wrapping plastics centre circle, plastics centre circle outer wrapping flexible glue outer ring is once shaping on injection machine completes, and adds the combination force between flexible glue and plastics; The utility model design is ingenious, rational in infrastructure, has dust-proof, grease proofing, subtracts the effect of sound, noise reduction.
Accompanying drawing explanation
Fig. 1 is structure sectional view of the present utility model.
Embodiment
