Abstract
The utility model relates to a sprocket, in particular to an assembly type one-way sprocket. The assembly type one-way sprocket mainly solves the technical problems that one-way sprockets in the prior art are made integrally, multiple sprockets of different specifications need to be manufactured when matching with pull chains of different sizes, production cost is high, assembly is complicated, and the like. The assembly type one-way sprocket comprises a sprocket shaft (1), and is characterized in that a one-way hub (2) is sleeved on the sprocket shaft (1); grooves (3) in counterclockwise spiral or clockwise spiral distribution are arranged in the one-way hub; a rolling needle (4) is arranged in each groove; and the outer circle of the one-way hub is fixed with a sprocket pair (5) through a connector.
Description
Technical field
The utility model relates to a kind of sprocket wheel, especially relates to a kind of assembling type One-way chain wheel.
Background technique
One-way chain wheel generally can carry out unidirectional transmission, thereby prevents because gravity chain antikinesis.Chinese patent discloses a kind of novel One-way chain wheel (notice of authorization number: CN 2839746Y), it comprises sprocket wheel and unidirectional needle bearing, unidirectional needle bearing is packed in the endoporus of sprocket hub, interference fit can only relatively rotate between sprocket wheel and the unidirectional needle bearing in one direction between the two; In the endoporus of unidirectional needle bearing transmission part being housed, is Spielpassung between the two, and transmission part and unidirectional needle bearing can only relatively rotate in one direction; Transmission part is transmission shaft; Offer the circular groove of apportion and sprocket hub both sides on the transmission shaft, be provided with the circlip that compresses with the wheel hub end face in the groove; The spacing of two circular grooves and the width of sprocket hub are suitable; Unidirectional needle bearing comprises outer ring, needle roller and retainer, and the inner peripheral surface of outer ring is provided with wedge-shaped impression, and needle roller is installed in the groove by retainer, is provided with spring or shell fragment between each needle roller and the retainer.But this One-way chain wheel all is integral body to be made, and need make the sprocket wheel of a plurality of different sizes when cooperating the slide fastener of different size, and cost of production is bigger, assembles comparatively numerous and diverse.
The model utility content
The utility model technical issues that need to address provide a kind of assembling type One-way chain wheel, it mainly is that solution existing in prior technology One-way chain wheel all is that integral body is made, when cooperating the slide fastener of different size, need make the sprocket wheel of a plurality of different sizes, cost of production is bigger, the technical problem of the comparatively numerous and diverse grade of assembling.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
Assembling type One-way chain wheel of the present utility model, comprise sprocket shaft, be socketed with unidirectional wheel hub on the described sprocket shaft, be provided with into the groove that counterclockwise spirality or clockwise spirality are arranged in the unidirectional wheel hub, be provided with a needle roller in each groove, the cylindrical of unidirectional wheel hub fixedly has chain wheel pair by link.Chain wheel pair and unidirectional wheel hub are separately made, and when cooperating the chain of different size, the chain wheel pair that only needs to change One-way chain wheel gets final product, and need not whole replacing, assembles comparatively simple like this.The groove that the counterclockwise spirality of one-tenth in the unidirectional wheel hub or clockwise spirality are arranged can guarantee the chain wheel pair one-way rotation, makes that chain can only be to a direction motion.
As preferably, described link includes socket head screw, straight pin.Socket head screw, straight pin can be fixed together unidirectional wheel hub and chain wheel pair.
As preferably, be provided with clutch shaft bearing between described sprocket shaft and the unidirectional wheel hub, the two ends of clutch shaft bearing are respectively equipped with bearing shim, shaft block ring.Clutch shaft bearing can be so that sprocket rotation be more smooth and easy.
As preferably, the outer end of described sprocket shaft is provided with second bearing.Second bearing can be so that sprocket shaft be more smooth and easy rotationally.
Therefore, One-way chain wheel of the present utility model is separately made by unidirectional wheel hub and chain wheel pair, only need change chain wheel pair and get final product when cooperating the slide fastener of different size, and cost of production is less, assembles comparatively simple, simple and reasonable for structure.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Accompanying drawing 2 is side structure schematic representation of Fig. 1.
Component, position and numbering among the figure: sprocket shaft 1, unidirectional wheel hub 2, groove 3, needle roller 4, chain wheel pair 5, socket head screw 6, straight pin 7, clutch shaft bearing 8, bearing shim 9, shaft block ring 10, second bearing 11.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: the assembling type One-way chain wheel that this is routine, as Fig. 1, Fig. 2, comprise sprocket shaft 1, be socketed with unidirectional wheel hub 2 on the sprocket shaft, be provided with into the groove 3 that counterclockwise spirality or clockwise spirality are arranged in the unidirectional wheel hub, be provided with a needle roller 4 in each groove, the cylindrical of unidirectional wheel hub fixedly has chain wheel pair 5 by link.Link includes socket head screw 6, straight pin 7.Be provided with clutch shaft bearing 8 between sprocket shaft and the unidirectional wheel hub, the two ends of clutch shaft bearing are respectively equipped with bearing shim 9, shaft block ring 10.The outer end of sprocket shaft is provided with second bearing 11.
The above only is specific embodiment of the utility model, but structure characteristic of the present utility model is not limited thereto, any those skilled in the art is in field of the present utility model, and the variation of doing or modification all are encompassed among the claim of the present utility model.
Claims (4)
