Abstract
The utility model relates to a low impact bipatch profile of tooth conveying chain link joint belongs to the mechanical transmission field. This chain plate structure includes three profile of tooth and two round pin shaft holes, and wherein the both sides tooth is work gear, and intermediate tooth is the antifriction tooth. Especially, its both sides work gear outside flank profil is different from the sharp flank profil of current bipatch profile of tooth conveying chain link joint, but comprises an interior concave curve, and its curvature radius more than or equal to 3 pitch doubly. The advantage of this structure lies in making the wide meshing of the teeth of a cogwheel and outside work gear more steady, effective reduce the vibration, noise and wearing and tearing, obvious stability and the life who carries the chain that improve.
Description
Technical field
This utility model belongs to Machine Design manufacture and field of chain transmission it is adaptable to steady carrier chain on various pipeline
The carrier bar of bar.
Background technology
Silent chain is a kind of widely used important mechanical basic part, with its high speed, heavy duty, low noise, low abrasion etc.
Advantage, is widely used in mechanical transmission fields.Bipatch silent chain as a kind of emerging profile of tooth chain, due to its unit
Linear mass substantially reduces, and the application of silent chain be extend to transportation art, and it is provided simultaneously with silent chain and roller chain
Advantage.But the flank profil structure that works outside the bipatch profile of tooth carrier chain carrier bar both sides tooth of current design is straight line, it with
Standard sprocket is engaged on moment and completes, and shock and vibration, noise are all very big, and serious wear has had a strong impact on stablizing of conveyer
Property, accuracy and service life.
Utility model content
This utility model offer is a kind of to have the low impact bipatch profile of tooth carrier chain for indent flank profil for the outside work flank profil
Carrier bar, in order to solve existing bipatch silent chain in engagement process, vibratory impulse, noise are excessive, serious wear the problems such as.
This utility model be the technical scheme is that low impact bipatch profile of tooth carrier chain carrier bar has three flank profils,
Wherein both sides are work tooth, and middle is anti-attrition tooth, and the outside work flank profil of described work tooth is the curve of indent, and this curve
Radius of curvature be more than or equal to 3 times of pitch.
The utility model has the advantage of: compared to existing bipatch profile of tooth carrier chain link plate structure by work flank profil by
Straight line is changed into inner concave curve so that work flank profil is more nearly conjugation engagement with engaging of sprocket teeth, can effectively reduce defeated
Send vibration, impact, noise and the abrasion of chain, thus improve stability and the service life of chain.
Brief description
Fig. 1, low impact bipatch profile of tooth carrier chain link plate structure schematic diagram；
Fig. 2, existing bipatch profile of tooth carrier chain link plate structure schematic diagram.
Specific embodiment
Described low impact bipatch profile of tooth carrier chain link plate structure has and includes three profiles of tooth and two pin shaft holes, and wherein two
Side tooth is work tooth, and center tooth is anti-attrition tooth.Especially outside its work tooth, flank profil is different from traditional straight-side profile, is by one
Bar inner concave curve is constituted, and the radius of curvature of this curve is more than or equal to 3 times of pitches.
It is defeated that low impact bipatch profile of tooth carrier chain carrier bar described in the utility model not only includes round pin formula bipatch profile of tooth
Send chain carrier bar, also include relative rolling type bipatch profile of tooth carrier chain carrier bar.
Below in conjunction with the accompanying drawings this utility model is further described:
The structure of described low impact bipatch profile of tooth carrier chain carrier bar as shown in figure 1, wherein 101 and 103 is work tooth,
102 is anti-attrition tooth, and 104 is pin shaft hole.105th, 106 is the work tooth outer teeth profile being constituted with inner concave curve, and its radius of curvature is big
In the pitch equal to 3 times.
It is illustrated in figure 2 existing bipatch profile of tooth carrier chain link plate structure, wherein 201 and 203 is work tooth, and 202 are
Anti-attrition tooth, 204 is pin shaft hole, and 205 and 206 is the work tooth outer teeth profile being constituted with straight line.
Due to pressure angle when described low impact bipatch profile of tooth carrier chain carrier bar is just contacted with the standard sprocket gear teeth
It is far smaller than existing bipatch profile of tooth carrier chain carrier bar and pressure angle during standard sprocket gear teeth meshing, nibble closer to conjugation
Close, so the shock loading that the former produces is significantly lower than the latter.
Described low impact bipatch profile of tooth carrier chain carrier bar can effectively reduce Chain conveyer during vibratory impulse,
Noise, abrasion etc., improve stability, accuracy and the service life of pipeline.
