Description
Technical field
The utility model relates to mechanical transmission fields, discloses a kind of elastic dowel pin shaft coupling.
Background technique
Coupling is used to two axles (driving shaft and driven shaft) connected in different institutions to be made it jointly to rotate with the mechanical parts of transmitting torque.General coupling is that the transmission between pure metal coordinates, and mostly pin coupler is rigid coupling, especially adopt the flexible coupling of nylon pin more, due to inelastic component, to the uncompensated ability of various relative displacement, and shock resistance is poor, easily cause when moment is larger nylon pin unstable and frequently fracture, also the damage of pin coupler is caused, also other reason is had in working procedure, as unexpected power-off, misoperation, between parts, there is no enough buffer units, easily cause coupling to damage.In addition, on the heavy ore deposits such as excavator in machinery, usually use coupling to realize axial force transmission, traditional coupling operationally, easily produces resonance, larger and the fragile coupling of noise, and traditional coupling adopts flat key to connect, when transmitting high moment of torsion, produce stress concentration phenomenon, if things go on like this, coupling is caused to rupture.
Model utility content
Therefore, for the defect existed in above-mentioned prior art, the utility model provides a kind of and has certain compensation relativity shift ability, and has the elastic dowel pin shaft coupling of good shock resistance, when the efficient transmission maintaining moment of torsion, also improve the working life of coupling.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of elastic dowel pin shaft coupling, comprise drive end half-coupling, Partner half-coupling, pin, nut and elastic sleeve, main, the end of Partner coupling extends radially outwardly formation flange, flange is provided with circular hole, pin connects main through circular hole, Partner coupling, elastic sleeve is sheathed on pin, the circumference of described flange sidewall is evenly equipped with teeth groove, for installing serpentine spring, the inwall of described coupling offers internal spline, the sidewall of described coupling offers oilhole, described master, the end face of Partner half-coupling docking is equipped with groove, hard nylon rod is installed in groove.
Further: described hard nylon rod is arranged with elastic sleeve.
Further: the end face that described drive end half-coupling docks with Partner half-coupling can also be provided with polygonal boss, the end face of relative Partner half-coupling is then provided with the polygonal grooves matched with described polygonal boss.
Further: described polygonal boss is triangle.
Further: described boss overlaps flexible cover.
Further: the Circularhole diameter of Partner coupling flange is less than the Circularhole diameter of drive end coupling flange.
Further: described internal spline is involute inner spline.
From the above-mentioned description to the utility model structure, compared to the prior art, the beneficial effects of the utility model are: in moment of torsion transmittance process, force bearing point is not only pin, also together born by hard nylon rod, the elastic sleeve adopted has certain stiffness, and it is main, the circular hole that the flange of Partner semiaxis coupling distributes, rubbercushioned sleeve bearing coupling is made to have the ability of certain compensation relativity shift, and there is good shock resistance, internal spline is adopted to realize the connection with axle, centering is good, stress is concentrated little, bearing capacity is large, hard nylon rod is made to increase and reduce operational noise working life.
