Abstract
The utility model discloses a high speed toothed chain drive system and comprises a drive sprocket wheel, a driven sprocket wheel and a chain, wherein the inside tooth profile of a working chain plate of the chain is in outer convex curve shape, the outside tooth profile is in linear shape, the tooth profile of a sprocket wheel gear tooth which is connected with the working chain plate is in big negative shift involute shape, and both of the inside tooth profile and the outside tooth profile of the working chain plate are engaged with the sprocket wheel gear tooth. The high speed toothed chain drive system adopts the structure that the inside tooth profile and the outside tooth profile of the working chain plate are engaged with the sprocket wheel gear tooth and has the advantages of small contact stress, steady locating, high drive efficiency, low noise, small impact and vibration, reducing the polygon effect and prolonging the service life of tooth chains.
Description
Technical field
The utility model belongs to silent chain transmission system, is specifically related to a kind of silent chain transmission system meshing engagement structure that is suitable for the high speed transmission.
Background technique
Silent chain transmission system is a kind of widely used transmission system, and round pin formula silent chain transmission system is divided into outer gearing silent chain, interior engaging tooth shape chain.At present, a large amount of silent chain transmission systems that use such as the motor of numerous automobiles, motorcycle, fork truck etc., existing outer gearing silent chain also has interior engaging tooth shape chain.
The outer gearing silent chain be with work carrier bar outside straight-side profile contact with the sprocket tooth of straight line profile of tooth, the location that contacts of work carrier bar and sprocket tooth, see it is line contact from end face, its inboard flank profil is to be inner concave curve or rectilinear form, and its inboard flank profil does not participate in the engagement with the gear teeth; This mesh form, contact stress is less, positioning stablity.But finish instantaneous because contact is located, thereby polygon effect is more serious, shock and vibration are bigger, and noise is big, and transmission efficiency is low.
Interior engaging tooth shape chain be with work carrier bar the inside curve flank profil contact with sprocket tooth, the both sides lineal shape outer teeth profile of interior engaging tooth shape chain is not participated in the engagement with sprocket wheel directly.The location that contacts of interior engaging tooth shape chain work carrier bar and sprocket wheel is a contact from end face, and point of contact moves in engagement process gradually, and slide relative is bigger, and it is more serious to wear and tear, and causes the silent chain life-span shorter.
The model utility content
In order to overcome the above-mentioned defective that the known technology field exists, the purpose of this utility model is, provides a kind of contact stress less, positioning stablity, transmission efficiency height, the high speed silent chain transmission system of the inside and outside compound engagement that noise is little, impact force and vibration are less.
The high speed silent chain transmission system that the utility model provides, comprise drive sprocket, driven sprocket, chain, the inboard flank profil of the work carrier bar of described chain is the curve shape of evagination, outside flank profil is shape linearly, and the flank profil of the sprocket teeth that contacts with the work carrier bar is the involute shape of big negative addendum modification; Inboard flank profil, the outside flank profil of work carrier bar all participate in and the engagement of sprocket teeth.
The high speed silent chain transmission system that the utility model provides, the inboard flank profil of employing work carrier bar, the structural type that outside flank profil all participates in and sprocket teeth meshes, the engagement contact stress is less, positioning stablity, the transmission efficiency height, noise is little, has reduced polygon effect, impact force and vibration are less, long service life.

Embodiment
With reference to the accompanying drawings, in conjunction with an embodiment, provide being described in detail of high speed silent chain transmission system to the utility model.
Embodiment
With reference to Fig. 1,2,3,4, the high speed silent chain transmission system of present embodiment, it is the silent chain transmission system of motor car engine, comprise drive sprocket 3, driven sprocket 1, chain 2, described chain 2 comprises work carrier bar 4, guide plate 5, and guide plate 5 is arranged on 4 liang of outsides of two row's work carrier bars, work carrier bar 4 and guide plate 5 wrong empty arrangements, and, form the chain of a sealing by the bearing pin connection; The inboard flank profil 7 of the work carrier bar 4 of described chain 2 is the curve shape of evagination, and outside flank profil 6 is shape linearly, and the flank profil of the sprocket teeth 8 that contacts with work carrier bar 4 is the involute shape of big negative addendum modification; Inboard flank profil 7, the outside flank profil 6 of work carrier bar 4 all participate in and the engagement of sprocket teeth 8.
Claims (1)
1. high speed silent chain transmission system, comprise drive sprocket, driven sprocket, chain, it is characterized in that: the inboard flank profil of the work carrier bar of described chain is the curve shape of evagination, outside flank profil is shape linearly, and the flank profil of the sprocket teeth that contacts with the work carrier bar is the involute shape of big negative addendum modification; Inboard flank profil, the outside flank profil of work carrier bar all participate in and the engagement of sprocket teeth.
