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 drive sprocket 2 is by duplex chain wheel 20, single gear ring 21, four rubber rings 22, screws 23 and pin and 24 form;
The tooth phase difference of half tooth-shape angle of two sprocket wheels in the described duplex chain wheel 20;
Described single gear ring 21 is connected on the duplex chain wheel 20 through screw 23 coaxially, the tooth phase difference of half tooth-shape angle of single gear ring 21 and adjacent sprocket wheel;
Described four rubber rings 22 are fixed on the both sides of three sprockets of two sprocket wheels and the single gear ring 21 of duplex chain wheel 20 through 24 compartment of terrains of pinning.
The circular arc of described guide card 13 bottoms and rubber ring 22 contact through interference fit; Thereby guarantee when the initial guide card 13 of engagement contacts with rubber ring 22; Bigger resiliently deformable can take place in point of contact; Reduce vibration, reduce the noise of system, help the raising of this silent chain transmission system overall performance.
The structure of described driven sprocket 3 is identical with drive sprocket 2, during assembling and drive sprocket 2 phase difference of half tooth-shape angles, realizes 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 the sprocket wheel that adds rubber ring partly to be converted into soft impulse to rigid impulse, alleviated the vibration in the engagement process, reduced the engagement noise, improved the combination property of chain drive system effectively.The design that three row's sprocket wheels are connected with spline can make the utility model be applicable to the high-speed overload chain drive system, also is applicable to the occasion that transmission efficiency and required precision are higher.
