Abstract
The invention discloses a composite-structured pulley which comprises a nylon wheel body, and the nylon wheel body is provided with a rope race and an oil injection nozzle; the composite-structured pulley also comprises a rotating shaft and a bearing thereof, the rotating shaft is movably connected with the wheel body, a bushing is arranged between the inside of the wheel body and the bearing, the two axial ends of the rotating shaft are respectively sleeved with a dust shield, and the dust shield is provided with an oil hole. By using the composite-structured pulley disclosed by the invention, the operation speed and carrying capacity of the pulley can be greatly improved, and the occurrence of a situation that the bearing has loose and traveling phenomenon occurring in the process of running because the expansion coefficients of the bearing and nylon are different when the bearing is directly contacted with the nylon can be avoided, thereby improving the service time of the bearing; and because the dust shield is provided with an oil hole, the bearing can be cleaned conveniently without removing the whole pulley.
Description
Technical field
The present invention relates to a kind of pulley, particularly a kind of composite structure pulley.
Background technology
Nylon pulley is widely used in the elevator, and at present nylon pulley commonly used exists following defective in the elevator: one, because bearing produces when making the bearing operation because of coefficient of expansion is different with the nylon direct contact and becomes flexible and move about, bring potential safety hazard; Two, the bearing end exposes in air for a long time and very easily suffers erosion, and influences the life-span of bearing; Three, change oil is more time-consuming.
Summary of the invention
In order to overcome above-mentioned defective, the invention provides a kind of composite structure pulley, this pulley can be used for the high live ladder of high speed, refuels and drains the oil conveniently, wheel and bearing long service life.
The present invention for the technical scheme that solves its technical matters and adopt is:
A kind of composite structure pulley; comprise the nylon wheel body that is provided with grooving; described wheel body is provided with zerk; also comprise the rotating shaft and the bearing thereof that are movably connected on wheel body; be provided with lining between described wheel body inboard and the bearing; the axial two ends of described rotating shaft are arranged with cover of dust respectively; described cover of dust is provided with oilhole; cover of dust available metal material also can be made of non-metallic material; also available engineering plastics die casting forms, owing on the cover of dust oilhole is arranged, can bleed off sump oil at any time; dismantle cover of dust with regard to the dirty oil in the clear bearing of energy, and need not dismantle a complete set of pulley and shutdown operation.
As a further improvement on the present invention, described cover of dust is provided with screw, and bolt passes screw cover of dust is fixed in lining.
As a further improvement on the present invention, the cover of dust surface is provided with some grooves, and groove is the loss of weight groove.
As a further improvement on the present invention, the inboard of described cover of dust axis hole is provided with seal groove, is provided with seal ring in the seal groove, and cover of dust upper shaft hole place can establish annular seal groove, can put seal ring, also can be coated with into the grease dust protection to enter in groove.
As a further improvement on the present invention, described lining is a metal lining.
As a further improvement on the present invention, described lining is bolted to connection in wheel body.Nylon wheel has added metal lining, can improve elevator speed more than one times than common nylon wheel, and load-carrying increases more than 50 percent.
The invention has the beneficial effects as follows:
One, the present invention has added metal lining in the nylon wheel body, can improve the running velocity and the load-carrying of pulley greatly, can prevent that again bearing from producing loosening and motility when causing the bearing operation with the nylon direct contact, because of coefficient of expansion is different.
Two, the present invention is provided with cover of dust for bearing, and the protection bearing is avoided extraneous and corroded the service life of having improved bearing.
Three, the present invention is provided with oil outlet on cover of dust, can bleed off the dirty oil of part during oiling, and bearing cleaning is very convenient, and whole pulley need not to dismantle.
Description of drawings
Fig. 1 is the axial cross-sectional schematic of the present invention.

Described cover of dust 6 is provided with screw, and bolt 9 passes screw cover of dust 6 is fixed in lining 5.
Cover of dust 6 surfaces are provided with some grooves, and groove is the loss of weight groove.
The inboard of described cover of dust 6 axis holes is provided with seal groove 8, is provided with seal ring in the seal groove, and cover of dust 6 upper shaft hole places can establish annular seal groove, can put seal ring, also can be coated with into the grease dust protection to enter in groove.
Described lining 5 is a metal lining.
Described lining 5 is fixedly connected on wheel body 1 by bolt 10, and nylon wheel has added metal lining, can improve elevator speed more than one times than common nylon wheel, and load-carrying increases more than 50 percent.
