Abstract
The utility model relates to an integrated star wheel non-return device with a plurality of rollers, comprising a non-return seat and a star wheel installed on a rotary shaft, wherein at least one roller is embedded on the excircle of the star wheel; guide cover plates installed on the star wheel are disposed at the two axial ends of the roller; and an integrated hub is connected to one side of the non-return seat. The non-return device is small in volume, light in weight, compact in structure, low in cost, low in noise, less in wear and long in service life.
Description
Technical field
The utility model relates to a kind of non-return device, relates in particular to a kind of many rollers integrated type star-wheel non-return device.
Background technique
Traditional star-wheel non-return device is mainly linked into an integrated entity by front stall, bonnet, check hub, and structure is huge, and volume is heavy; Star-wheel is installed the back, and axially play is big; Because the defelctor apron periphery contacts with check hub inwall; Cause solid of rotation to contact, produce big friction noise during work, because the influence of this friction with non-rotary body; Make two cover plates that roller is play the guiding role yielding, can not guarantee the accurate guiding of roller in the non-return device working procedure; In addition, it is on the low side that traditional non-return device is joined the roller number, generally is less than five, and braking moment is little, and simple grain roller contact stress is big, and using effect is undesirable, thereby cause the non-return device operational failure.
Summary of the invention
In order to solve the deficiency that traditional non-return device exists, the utility model provides a kind of little, simple in structure, easy accessibility of rubbing, many rollers integrated type star-wheel non-return device that cost is low.
The technological scheme that the utility model adopts is: a kind of many rollers integrated type star-wheel non-return device; Comprise the check seat and be installed on the star-wheel on the running shaft; Be embedded with at least one roller on the star-wheel cylindrical; The axial two ends of roller are provided with the defelctor apron that is installed on the star-wheel, and its technical characterstic is that a side of said check seat connects the disjunctor hub.
Further, said disjunctor hub one side is provided with adjusting screw, and an end of adjusting screw stretches into disjunctor hub inner chamber and is the Spielpassung state with star-wheel.
Again further, said roller number is more than or equal to five.
After adopting above technological scheme, the beneficial effect that the utility model reaches is:
1, because the disjunctor hub both uses as active chamber, have the bonnet effect simultaneously, save traditional bonnet, make active chamber with
Bonnet is an one, makes the smaller volume of this non-return device, weight saving, and structure is more compact, and manufacture cost obviously reduces;
2, the friction through roller and disjunctor hub inwall realizes check, and check speed is fast, and check is steady, and the increase of the reasonable quantity of roller, can reduce the contact stress of single roller, has significantly improved the check moment of torsion;
3, because the periphery and the disjunctor hub inwall gap of defelctor apron are bigger, reduce friction noise significantly, wearing and tearing are few, long service life.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the sectional view of Fig. 1.
Among the figure, check seat 1, disjunctor hub 2, star-wheel 3, defelctor apron 4, axle card 5, bolt 6, adjusting screw 7, roller 8, ejector pin 9, spring 10, " 7 " font groove 11, pin-and-hole 12, running shaft 13.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
As shown in Figure 1, a kind of many rollers integrated type star-wheel non-return device comprises check seat 1, disjunctor hub 2, and star-wheel 3, running shaft 13, check seat 1 is fixedly mounted on the body, and disjunctor hub 2 is connected as a single entity through bolt 6 with check seat 1; Running shaft places check seat and disjunctor hub inner chamber, and star-wheel 3 is installed on the running shaft 13 and places disjunctor hub inner chamber; Be interval with many group " 7 " font grooves 11 and pin-and-hole 12 on the cylindrical circumference of star-wheel 3, be provided with roller 8 in " 7 " font groove 11, be provided with ejector pin 9 in the pin-and-hole 12, be with spring 10 on the ejector pin 9; The axial two ends of roller 8 are provided with the defelctor apron 4 that is fixed on the star-wheel, and defelctor apron 4 is through axle card 8 location, and roller 8 moves in 4 rotations with star-wheel of two defelctor aprons; Disjunctor hub 2 one sides are provided with adjusting screw 7, and an end of adjusting screw 7 stretches into disjunctor hub 2 inner chambers and is Spielpassung with star-wheel 3, and adjusting screw is carried out axially locating to star-wheel.
When running shaft drive star-wheel rotated counterclockwise synchronously, roller and disjunctor hub inwall produce active force made roller to the displacement of ejector pin direction, and ejector pin is compressed into pin-and-hole under the roller effect, and the frictional force between roller and disjunctor hub is very little, and non-return device does not have the check effect at this moment; When because outage or other factors cause running shaft to drive star-wheel when clockwise rotating, to ejector pin displacement in the other direction, roller produces with disjunctor hub inwall and rubs roller, thereby running shaft is braked under the effect of spring and ejector pin, the realization check.
Claims (3)
1. the star-wheel of roller integrated type more than kind non-return device; Comprise the check seat and be installed on the star-wheel on the running shaft; The star-wheel cylindrical is embedded with at least one roller, and the axial two ends of roller are provided with the defelctor apron that is installed on the star-wheel, it is characterized in that: a side of said check seat connects the disjunctor hub.
2. many rollers integrated type star-wheel non-return device according to claim 1 is characterized in that: said disjunctor hub one side is provided with adjusting screw, and adjusting screw stretches into disjunctor hub inner chamber and is the Spielpassung state with star-wheel.
3. many rollers integrated type star-wheel non-return device according to claim 1, it is characterized in that: said roller number is more than or equal to five.
