Description
Technical field
The utility model relates to a kind of silent chain, especially a kind of car engine timing internal messing tooth form chain.
Background technique
Internal messing silent chain is the chaindriven important branch of flute profile, it is better because having compared with outer meshing silent chain
Mechanical property, lower noise, so starting the timing chain for serving as engine extensively.The same chain of existing internal messing silent chain
Section is composed of multi-disc carrier bar, and the bearing area of carrier bar is smaller, so that the bearing capacity of carrier bar is weaker；Simultaneously because a chain
Carrier bar number in section is more, cause all carrier bars cannot stress simultaneously, reduce the bearing capacity of carrier bar, the fixation of pin shaft is not yet
Stablize, causes the ability of chain absorbed impact weaker.Moreover, the abrasion between existing chain and sprocket wheel is also more serious,
So that the service life of chain is shorter.Therefore, existing technology has that impact resistance ability is poor and chain is easy to wear.
Utility model content
The purpose of the utility model is to provide a kind of car engine timing internal messing tooth form chains.This is practical new
Type has the characteristics that can be improved impact resistance ability and reduces chain wear.
The technical solution of the utility model includes: car engine timing internal messing tooth form chain, including being located at determining for middle part
Position carrier bar, positioning 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
With the outer guide plate for connecting carrier bar dislocation arrangement, it is connected between outer guide plate, connection carrier bar and positioning carrier bar through pin shaft；The connection chain
The tooth contract angle of plate and positioning carrier bar is 63-67 °, and connection carrier bar and the thickness for positioning carrier bar are 2.1-2.3mm.
Car engine timing above-mentioned is in internal messing tooth form chain, the connection carrier bar and the tooth contract angle for positioning carrier bar
It is 65 °.
With in internal messing tooth form chain, connection carrier bar and the thickness for positioning carrier bar are car engine timing above-mentioned
2.2mm。
For car engine timing above-mentioned in internal messing tooth form chain, the spacing between adjacent pin shaft is 8mm.
For car engine timing above-mentioned in internal messing tooth form chain, the both ends of the pin shaft are equipped with riveter.
For car engine timing above-mentioned in internal messing tooth form chain, the connection carrier bar and positioning carrier bar include chain
Plate ontology, carrier bar body lower part are set there are two the sprocket that is arranged symmetrically, are equipped with arc groove between two sprockets, in arc groove
Portion is equipped with arc notch.
Compared with prior art, the utility model has been made excellent by the shape and size to positioning carrier bar and connection carrier bar
Change, the tooth contract angle for positioning carrier bar and connection carrier bar is expanded as 63-67 °, so as to increase the contact loaded area of carrier bar, is subtracted
Small friction, and then the bearing capacity of carrier bar is improved, the bearing capacity of internal messing tooth form chain entirety is improved, so that internal messing tooth form
Chain is able to bear high-intensitive impact；The thickness for positioning the single carrier bar of carrier bar and connection carrier bar is increased into 2.1-2.3mm,
The carrier bar number that same chain link is reduced with this is enable the carrier bar while stress of same chain link, reduces the contact of hinges contact surface
Than pressure value, the abrasion of chain is greatly alleviated, can also further increase the ability that chain absorbs impact, while also making chain
Item has 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.
Internal messing tooth form chain using the above structure, compared with traditional silent chain, tensile strength improves 45% or more, impact resistance energy
Power improves 30% or more, and antiwear property improves 30% or more；Make car engine timing chain using the internal messing silent chain,
The bulk that engine can be reduced makes engine lightweight, miniaturization, reduces the oil consumption of engine, reduces rotational noise.This
Utility model has the characteristics that can be improved impact resistance ability and reduces chain wear.
In addition, by the way that arc notch is arranged at the middle part of connection carrier bar and the arc groove for positioning carrier bar, it can either be effective
The heat dissipation improved between chain and sprocket wheel, and can be improved the stability being driven between chain and sprocket wheel.
