Abstract
The utility model discloses a kind of mute synchronous pulleys, including sliding support, two shafts being mounted on sliding support and two pairs of idler wheels, each pair of idler wheel is bolted respectively at the both ends of shaft, the sliding support is equipped with perforation corresponding with shaft, it is characterized by: being arranged with a wear-resistant sleeve made of non-metallic material in the middle part of the shaft, the both ends of the shaft are arranged with mute positioning sleeve respectively, the mute positioning sleeve is step-like, in the small one end insertion perforation of its diameter, the big one end of diameter is withstood on the end face of perforation.The idler wheel of the utility model is bolted in shaft respectively, idler wheel both can rotation, shaft can also be followed to rotate together, to realize easily sliding, meanwhile wear-resistant sleeve is arranged in the middle part of shaft, it is arranged with mute positioning sleeve respectively at the both ends of shaft, to reduce vibration, eliminate noise, achieve the effect that mute sliding.
Description
Technical field
The utility model relates to a kind of pulley accessories, and in particular to a kind of mute synchronous pulley.
Background technique
It is generally used for the pulley of sliding door or overhang-door, is generally disposed at sliding door top surface or top, which includes fixed station
And two wheel groups of platform are connected and fixed, major function is to stablize support sliding door and reduces the mobile frictional force of sliding door.It is conventional sliding
Wheel construction includes sliding support, the shaft and roller group that are mounted on sliding support, and metal rivet connects after passing through roller group
In shaft.Sliding support, roller group, shaft, metal rivet are metalwork, are easy to produce biggish make an uproar in use
Sound.Simultaneously as there are certain gaps for the installation of roller group, shaft, two groups of idler wheels in front and back easy to form are not conplane
Situation, the degree of balance is inadequate, and stress is made to concentrate on the same wheel group, causes to pull mobile not smooth enough or reduction wheel group using resistance to
Degree long.
Utility model content
For overcome the deficiencies in the prior art, the utility model provides a kind of anti-pressure and abrasion-proof, mute smoothly mute synchronization
Pulley.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
A kind of mute synchronous pulley, including sliding support, two shafts being mounted on sliding support and two pairs of idler wheels, often
Idler wheel is bolted respectively at the both ends of shaft, the sliding support is equipped with perforation corresponding with shaft, feature
It is: is arranged with a wear-resistant sleeve made of non-metallic material in the middle part of the shaft, the both ends of the shaft is arranged with respectively
Mute positioning sleeve, the mute positioning sleeve be it is step-like, diameter it is small one end insertion perforation in, the big one end of diameter, which is withstood on, wears
On the end face in hole.
In the present invention, the idler wheel includes plastic wear-resisting tire, wheel rim, the bearing being mounted in the middle part of wheel rim, sets
Set the bolt connecting hole in portion within the bearing.
In the present invention, the lateral surface of the wear-resistant sleeve is dome shape.
In the present invention, it is equipped with protrusion or recessed axial positioning structure in the middle part of the shaft, the wear-resistant sleeve
Inner ring is equipped with corresponding recessed or bulge-structure.
The beneficial effects of the utility model are: the idler wheel of the utility model is bolted in shaft respectively, idler wheel
Both can rotation, shaft can also be followed to rotate together, with realize easily sliding, meanwhile, wear-resistant sleeve is arranged in the middle part of shaft,
The both ends of shaft are arranged with mute positioning sleeve respectively, to reduce vibration, eliminate noise, achieve the effect that mute sliding.Further,
The both ends of shaft are muted positioning sleeve and are limited, and will not generate axile displacement, make two groups of front and back idler wheel in the same plane, guarantee
The degree of balance keeps its sliding more smooth；Due to being limited using mute positioning sleeve, the length of shaft will not be limited,
Longer shaft can be used to adapt to broader sliding slot.
Detailed description of the invention
The present invention will be further described with embodiment with reference to the accompanying drawing:
Fig. 1 is the structural schematic diagram of the present embodiment；
Fig. 2 is the main view of Fig. 1；
Fig. 3 is the A-A sectional view of Fig. 2；
Fig. 4 is the explosive view of the present embodiment.
Specific embodiment
Referring to figs. 1 to Fig. 4, the mute synchronous pulley of one kind provided by the present embodiment, including sliding support 1, it is mounted on cunning
Two shafts 2 and two pairs of idler wheels 3, the sliding support 1 on dynamic bracket 1 are made of metal material, and middle part is equipped with for connecting
The connecting hole of door and window, the height of sliding support are less than the diameter of idler wheel 3, and both direction can be used entire pulley up and down.It is each pair of
Idler wheel 3 is connected to the both ends of shaft 2 by bolt 4 respectively, and the sliding support 1 is equipped with perforation 5 corresponding with shaft 2, institute
The diameter for stating perforation 5 is greater than the diameter of shaft 2, and the middle part of the shaft 2 is arranged with a wear-resistant sleeve made of non-metallic material
6, the both ends of the shaft 2 are arranged with mute positioning sleeve 7 respectively, and the mute positioning sleeve 7 is step-like, small one end of diameter
Insertion perforation 5 in, the big one end of diameter withstand on perforation 5 end face on, and the external end face of the big one end of diameter substantially with shaft 2
End face is concordant.The mute positioning sleeve 7 is made of wear-resistant plastic, while fixed rotating shaft 2, achievees the effect that damping, mute.
As preferred embodiment, the lateral surface of the wear-resistant sleeve 6 is dome shape 8, is equipped with protrusion in the middle part of the shaft 2
Or recessed axial positioning structure, the inner ring of the wear-resistant sleeve 6 are equipped with corresponding recessed or bulge-structure, since wear-resistant sleeve 6 has
There is certain deformability, is directly inserted in shaft 2 in production.
In the present embodiment, the idler wheel 3 includes plastic wear-resisting tire, wheel rim, the bearing being mounted in the middle part of wheel rim, setting
The bolt connecting hole in portion within the bearing, the structure are conventional structure, be will herein be described in detail.
The foregoing is merely the preferred embodiments of the utility model, as long as realizing the utility model with essentially identical means
The technical solution of purpose belongs within the protection scope of the utility model.
