Summary of the invention
The purpose of this utility model be to solve above-mentioned existing silent chain technology can only one side transmission, chain drive system serious wear, noise is large, can not transmit excessive power and torque, the problems such as chaindriven application is restricted, and a kind of silent chain complex phase multi-axle drive mechanism is provided.
The utility model is made up of the first chain, the second chain, the first drive sprocket, the second drive sprocket, the first driven sprocket and the second driven sprocket, first chaining bar engagement is arranged on the first drive sprocket and the first driven sprocket, and the second chaining bar engagement is arranged on the second drive sprocket and the second driven sprocket;
First chain is identical with the second chain structure, be made up of by hinge with positive and negative serial connection several carrier bar, carrier bar is wide waist type round pin silent chain, chain plate hole internal diameter is slightly larger than pin diameter, inside carrier bar, flank profil is circular arc type, outside flank profil is straight line type, and the distance b bottom chain plate hole center to the distance a and chain plate hole center to carrier bar of chain plate top surface is equal;
First drive sprocket is arranged on the second drive sprocket surely, and differ half tooth-shape angle, first driven sprocket is fixedly installed on the second driven sprocket, and differing half tooth-shape angle, sprocket wheel is involute sprocket wheel, and sprocket tooth profile is involute, sprocket tooth root line is straight line, sprocket wheel number n is more than or equal to 2, and the phase angle 360/nz differed between sprocket wheel changes with the difference of n, and wherein z is the number of teeth of sprocket wheel.
Working principle of the present utility model and process:
According to different needs, required number of phases n is set, in first chain and the first driven sprocket engagement process, the inner arc flank profil of carrier bar engages with the first driven sprocket sprocket tooth profile, along with the rotation of sprocket wheel, carrier bar exits engagement, the outside straight-side profile of carrier bar starts to engage with driven sprocket sprocket tooth profile, and in carrier bar, outer teeth profile replaces and sprocket engagement, and chain is identical with the engagement process of drive sprocket, driven sprocket, transmit power by driving wheel, realize chain drive system.
The beneficial effects of the utility model:
The utility model structure is simple, it is convenient to change, application is strong, larger power and moment of torsion can be transmitted, utilize two-phase superposition principle and humorously accordingly should to be related to, complex phase transmission obviously can reduce vibrations that polygon effect causes and impact, reduces the noise of drive system, the overall performance of effective raising system;
In adopting-and outer compound engagement, reduce the polygon effect of chain, in carrier bar, outer teeth profile alternately contacts with sprocket engagement simultaneously, reduces the wearing and tearing of carrier bar, increases the life-span of carrier bar;
Sprocket wheel involute profile has the effect reducing mesh impact in engagement process, and relatively little with the contact stress of chain contact moment, ensure that the stationarity of drive system, sprocket tooth root line is straight line, ensure that the correct engagement of carrier bar and sprocket wheel.
