Abstract
The invention provides a tooth-shaped chain for high-speed transmission of a novel meshing mechanism. The tooth-shaped chain comprises a tooth-shaped chain plate and a guide plate which are connected together through pin shafts, wherein the tooth-shaped chain plate is formed by combining any two of an outer meshing chain plate, an inner-outer composite meshing chain plate and an inner meshing chain plate. According to the tooth-shaped chain, the polygonal effect is relieved, and impact, vibration and noise are reduced, so that transmission is steadier, and the smoothness under the high-speed transmission is greatly improved; the tooth-shaped chain is particularly suitable for high-speed, speed-variable and load-variable chain transmission systems such as an automobile, a motorcycle and an airplane.
Description
Technical field
Patent of the present invention relates to technical field of chain transmission, particularly relates to the high-speed drive tooth of a kind of new meshing mechanism
Shape chain.
Background technology
Silent chain is widely used in the chain drive systems such as automobile, motorcycle, aircraft.According to the difference of mesh mechanism,
Silent chain can be divided into internal messing silent chain, outer meshing silent chain and interior-outer compound engaging tooth shape chain.The work of outer meshing silent chain
Face is the outside flank profil of carrier bar, positioning stablity, but completes owing to the location of carrier bar is instantaneous, and impact noise is big.Internal messing profile of tooth
The work surface of chain is inner arcuate flank profil, it is possible to reduces polygon effect, alleviates vibration, but due to chain and sprocket interface
Long-pending little, quick abrasion.Interior-outer compound engaging tooth shape chain has the advantage of internal messing silent chain and outer meshing silent chain, transmission process concurrently
In be first that carrier bar inner arcuate flank profil contacts with sprocket faces, along with engagement carrying out, outside carrier bar work surface is gradually by inner side
Double wedge exterior feature is changed into outside flank profil, finally realizes external toothing location.During this, bearing pin two side bus and chain plate hole both sides are handed over
For stand under load, reduce the abrasion of carrier bar, bearing pin and sprocket faces.But at some high-speed drives and require that stable drive is quiet
Under environment, due to its polygon effect, its polygon effect of increase especially with pitch is increasing, causes silent chain to pass
Dynamic impact shock aggravation, noise is relatively big, affects the chaindriven precision of high speed and the performance of high-end main frame, and can not meet high-end
Main frame individual demand high performance to high-end product.
Summary of the invention
Patent of the present invention provide a kind of new meshing mechanism high-speed drive profile of tooth chain, solve cannot meet high-end
The problem of the performances such as main frame high accuracy chaindriven to high speed profile of tooth low noise, meets high-end main frame to high-end product high-performance
Individual demand.
The high-speed drive profile of tooth chain of a kind of new meshing mechanism that the present invention provides, including tooth shape chain board and guide plate,
Both are linked together by bearing pin；Tooth shape chain board is by external toothing carrier bar, interior-outer compound engagement carrier bar, internal messing carrier bar three kinds
In profile of tooth, any two kinds combine.
Outside external toothing carrier bar, internal messing carrier bar, interior-outer compound engagement carrier bar, flank profil is straight line, internal messing carrier bar and
Interior-outer compound engagement carrier bar inner tines exterior feature is circular arc, and inside external toothing carrier bar, flank profil is straight line.
The combining form 1 of the present invention is: tooth shape chain board is by external toothing carrier bar, interior-outer compound engagement carrier bar alternate combinations
Becoming, external toothing carrier bar and interior-outer compound engagement carrier bar quantity are 1:1～4:13 than scope.
The combining form 2 of the present invention is: tooth shape chain board is by internal messing carrier bar, interior-outer compound engagement carrier bar alternate combinations
Becoming, internal messing carrier bar and interior-outer compound engagement carrier bar quantity are 1:1～4:13 than scope.
The combining form 3 of the present invention is: tooth shape chain board is formed by external toothing carrier bar, internal messing carrier bar alternate combinations, nibbles outward
Close carrier bar and internal messing carrier bar quantity is 1:1～3:2 than scope.
The form of concrete carrier bar permutation and combination away from factors such as, chain lengths according to teeth number of sprocket, centre of sprocket, uses and calculates
Machine emulation technology simulative optimization permutation and combination parameter.
The present invention also provides for a kind of high-speed drive silent chain, including drive sprocket, driven sprocket and above-mentioned chain, chain
Engage with drive sprocket, driven sprocket.
The high-speed drive silent chain of the new meshing mechanism that the present invention provides, it has the beneficial effects that, with external toothing tooth
Shape chain, internal messing silent chain are compared with interior-outer compound engaging tooth shape chain, and combining form 1 can have external toothing, interior-outer concurrently simultaneously
The advantage of compound mesh mechanism, combining form 2 can have internal messing, the advantage of interior-outer compound mesh mechanism simultaneously concurrently, combine shape
Formula 3 can have external toothing and the advantage of internal messing mechanism concurrently simultaneously.Three kinds of combining forms are all to form according to a definite sequence arrangement
The silent chain transmission of alternately mixing engagement, reduce polygon effect, reduce shock and vibration and noise, improve wear-resisting
Performance.During working conditions change, optimize carrier bar assembled arrangement form, meet client's high-quality requirement to catenary system.
This silent chain reduces polygon effect, reduces shock and vibration and noise, and transmission is more steady, substantially increases
Ride comfort under its high-speed drive, is especially suitable for high speed, the chain drive systems of speed change variable load such as automobile, motorcycle, aircraft.

Detailed description of the invention
Below in conjunction with a case study on implementation, the high-speed drive silent chain of the new meshing mechanism providing the present invention is carried out
Describe in detail.
The present embodiment is certain automobile gearbox transmission silent chain, it include bearing pin 1., interior-outer compound engagement carrier bar 2.,
External toothing carrier bar 3., guide plate 4..In described-it is combined outward 3. 2. engagement carrier bar (do not have 2 and 3) with external toothing carrier bar outside on figure
Flank profil is straight line, and interior-outer compound engagement carrier bar 2. inner side flank profil is circular arc, and external toothing carrier bar outside flank profil 3. is straight line.
