Description
Technical field
The utility model relates to a kind of tooth form chain structure, especially a kind of high-intensitive silent chain.
Background technique
Existing silent chain uses in high-revolving use environment, is subjected to high-intensitive impact force, and traditional tooth
The impact resistant strength and tensile strength of shape chain are undesirable, cause the service life of silent chain shorter；Moreover, existing silent chain
It is made of muti-piece carrier bar and outer guide plate, can be displaced sideways between adjacent carrier bar and carrier bar and guide plate, not only result in chain
Serious wear, can also generate vibration and noise.Meanwhile the stable drive performance of existing chain is also poor.Therefore, existing
Technology has that impact resistant strength is low, noise is big and stable drive performance is bad.
Utility model content
The purpose of the utility model is to provide a kind of high-intensitive silent chains.The utility model, which has, can be improved resistance to punching
Hit intensity reduces the characteristics of noise and improvement stable drive performance.
The technical solution of the utility model includes: a kind of high intensity silent chain, the positioning carrier bar including being located at middle part position carrier bar
Two sides are equipped with the connection carrier bar with positioning carrier bar dislocation arrangement, are equipped on the outside of every block of connection carrier bar and connect carrier bar dislocation cloth
The outer guide plate set is connected between outer guide plate, connection carrier bar and positioning carrier bar through pin shaft；The connection carrier bar and the tooth for positioning carrier bar
Contract angle is 70-74 °, connect carrier bar with a thickness of 1.95-2.03mm, position carrier bar with a thickness of 2.20-2.33mm；Adjacent
Spacing between pin shaft is 6.2-6.4mm；It is interference fit between the pin shaft and outer guide plate and pin shaft and positioning carrier bar,
Connecting is clearance fit between carrier bar and pin shaft.
In a kind of high-intensitive silent chain above-mentioned, the tooth contract angle of the connection carrier bar and positioning carrier bar is 72 °.
In a kind of high-intensitive silent chain above-mentioned, connect carrier bar with a thickness of 2mm.
In a kind of high-intensitive silent chain above-mentioned, position carrier bar with a thickness of 2.3mm.
In a kind of high-intensitive silent chain above-mentioned, the spacing between adjacent pin shaft is 6.35mm.
In a kind of high-intensitive silent chain above-mentioned, the height of the connection carrier bar, positioning carrier bar and outer guide plate is
7.63mm。
Compared with prior art, in the case where equal tensile strength and same space layout, the utility model pass through by
Spacing, that is, carrier bar pitch reduction between adjacent pin shaft is to 6.2-6.4mm, so as to effectively improve the polygon of chain
Shape effect, and then greatly improve the stable drive performance of chain；Expanded by that will connect carrier bar and position the tooth contract angle of carrier bar
Greatly to 70-74 °, so as to increase the contact loaded area of carrier bar, and then the bearing capacity of carrier bar is improved, so that internal messing tooth
Shape chain is able to bear high-intensitive impact；And to connection carrier bar and position the thickness of carrier bar and done thickening processing, subtracted with this
The carrier bar number of few same chain link enables the carrier bar while stress of same chain link, reduces the specific contact pressure value of hinges contact surface, pole
The big abrasion for alleviating chain can also further increase the ability that chain absorbs impact, while it is good to have chain
Good stable drive performance；By reducing carrier bar number, moreover it is possible to the vibration of carrier bar is reduced, to reduce drive noise.This is practical new
Type reduces gap, makes to position by that will be set as being interference fitted between the outer guide plate of two sides and the positioning carrier bar and pin shaft of centre
Carrier bar does not generate lateral vibration during chain drive, reduces rotational noise, connects and is set as gap between carrier bar and pin shaft
Cooperation, allows chain flexible rotating on sprocket wheel.In conclusion the utility model, which has, can be improved impact resistant strength, drop
The characteristics of low noise and improvement stable drive performance.
