Abstract
The utility model discloses a novel transmission system with double sub tooth-shaped chains. The novel transmission system comprises rolling pin type tooth-shaped chains, a driving chain wheel and a driven chain wheel, wherein the rolling pin type tooth-shaped chains are in meshed transmission with the driving chain wheel and the driven chain wheel. Each rolling pin type tooth-shaped chain comprises a chain plate, a short pin, a long pin, a clamp ring, a clamp ring rubber pad, guide pieces and a guide piece rubber pad. The clamp ring fix two chains together through square holes on guide pieces on outer sides of the two chains. The two chains are fixed through the clamp ring, thereby reducing vibration of the two chains in the transmission process, converting rigid impact into flexible impact through the chain wheels with rubber rings, relieving the vibration in the meshing process, effectively reducing meshing noise and effectively improving comprehensive performance of a chain transmission system. The novel transmission system is suitable for a high-speed heavy-duty chain transmission system and also suitable for occasions with high requirements for transmission efficiency and accuracy.
Description
Technical field
The utility model belongs to the mechanical transmissioning technology field, is specifically related to a kind of novel gemini silent chain transmission system.
Background technique
Silent chain is a kind of widely used important mechanical basic part; Particularly under the operating mode of high speed, heavy duty, low noise and big centre distance; Its transmission performance is superior to toothed belt transmission, gear transmission and roller chain drives, has become one of first-selected type of belt drive of numerous industries.In recent years, motor car engine, speed changer, transfer case, motorcycle, fork truck, steam turbine, aircraft boats and ships, rolling machinery, lathe, industrial pump, and in other high speed transmissions, application more and more widely various silent chains.
General single chain tooth sprocket and the single chain of adopting of the drive sprocket of silent chain transmission system of the prior art; When carrier bar and sprocket engagement; Carrier bar is actually the line contact with contacting of sprocket wheel; Contact process is the process of " impact-bounce-back-impact again ", has rigid impulse between carrier bar and the sprocket wheel, and chain vibration is serious.In addition, the power that simple chainwheel transmits is big more, and the chain row number that needs is many more, and bearing pin is just long more, and the bearing pin stress deformation is just serious more, causes the transmission system overall performance relatively poor.
Existing Chinese patent (publication number is 201110356) discloses a kind of silent chain transmission system; But what it was related is a kind of round pin formula silent chain transmission system, and sprocket wheel is single, and rigid impulse is bigger with vibration in the transmission process; Noise is big; Contact points moves in contact process gradually, and slide relative is bigger, and it is more serious to wear and tear.
Summary of the invention
In order to overcome the deficiency of existing technology, the invention provides and a kind ofly have, be fit to the novel gemini silent chain transmission system of high speed, heavy duty, speed change, variable load operating mode than low noise and vibration.
The utility model is realized through following technological scheme:
A kind of novel gemini silent chain transmission system is mainly formed by rolling pin formula silent chain 1, drive sprocket 2 and driven sprocket 3, describedly rolls pin formula silent chain 1 and drive sprocket 2, driven sprocket 3 engagement driving, the transmission of realizable force and moment of torsion.
Described roll pin formula silent chain 1 by carrier bar 10, short pin 11, have strong market potential 12, guide card 13, guide card rubber pad 14, snap ring 15 and snap ring rubber pad 16 form; 11 and one of short pin have strong market potential 12 pass carrier bar 10 in pairs the chain plate hole; Adjacent two row's carrier bars 10 are coupled together, and 12 the two ends of having strong market potential exceed outermost chain plate hole certain altitude;
The profile in the guide card hole of described guide card 13 just in time is fixed in adjacent two external parts of 12 of having strong market potential with 12 the profile phase of having strong market potential with, guide card 13;
Through short pin 11, have strong market potential 12 and guide card 13 will arrange carrier bar 10 more and join end to end, thereby form many rows Transmitted chains of sealing.
Described guide card 13 sides have a square opening; Snap ring 15 is fixed together two chaining bars through the square opening on the outer side guiding plate of two chaining bars; Snap ring rubber pad 16 is adhesive in snap ring 15 inside, and in transmission process, snap ring rubber pad 16 contacts with carrier bar 10; Turn to hard and soft contact to the rigidity contact, reduce and impact and vibration.
Described guide card rubber pad 14 is adhesive in the arc groove of guide card top, have strong market potential 12 in the centre of two chaining bars one side stretch out the thickness of an about guide card, be pressed on the guide card rubber pad 14, stablely roll the vibration of pin formula silent chain 1 in transmission process.
Described drive sprocket 2 is by duplex chain wheel 20, sprocket wheel rubber ring 21 and pin and 22 form; The tooth phase difference of half tooth-shape angle that duplex chain wheel 20 is adjacent; Three sprocket wheel rubber rings 21 are fixed between the sprocket wheel and both sides through four with pin 22 respectively; Stablize sprocket wheel rubber ring 21, thereby guarantee that point of contact bigger resiliently deformable can take place comes buffering vibration when the initial guide card 13 of engagement contacts with sprocket wheel rubber ring 21.
Described sprocket wheel rubber ring 21 is an interference fit with contacting of guide card 13, and the interference when adopting interference fit to avoid meshing can make guide card 13 effectively contact with sprocket wheel rubber ring 21 again.
Because sprocket wheel rubber ring 21 has bigger distortion when stressed; Concentrate for fear of stress; On sprocket wheel rubber ring 21, be processed with transition arc with the teeth number of sprocket equal number; Thereby changed the amount of deformation of rubber ring when stressed, can increase the time of contact of rubber ring when being hit like this, effectively the impact during the buffering engagement.
Described driven sprocket 3 structures are identical with drive sprocket 2, during assembling and drive sprocket 2 phase difference of half tooth-shape angles, realize the dislocation engagement, and the rhythm and the frequency of regulating engagement reduce the engagement noise.
The beneficial effect of the utility model is: adopt snap ring to fix two chaining bars; Reduce two vibrations of chaining bar in transmission process; Sprocket wheel with adding rubber ring can partly be converted into soft impulse to rigid impulse; Alleviate the vibration in the engagement process, effectively reduced the engagement noise, improved the combination property of chain drive system effectively.Two row's chain hinge pins are alternate with each other, and the rhythm and the frequency that change engagement reduce the engagement noise, and the vibration that helps in the transmission process is complementary.Two row's sprocket wheels, the spline connection goes for the high-speed overload chain drive system, also goes for the higher occasion of transmission efficiency and required precision, thereby has set up a kind of efficient, general chain drive system.
