The model utility content
Main purpose of the present utility model is to provide a kind of novel stake mechanomotive force head height speed reducer, makes it can overcome retarder shake easily under working at high speed in the prior art, and the very big shortcoming of noise.
Stake mechanomotive force head height speed reducer described in the utility model, comprise motor, transmission shaft, bent axle, gear, central gear etc., wherein: four bent axles are symmetricly set in around the central gear, and described bent axle is three eccentric segment structures with 180 degree phase differences, and, two crankshaft end of central gear homonymy symmetry are equipped with actuation gear, the gear engagement of this actuation gear and above-mentioned transmission shaft end;
First, second, third eccentric segment of described bent axle is connected with first, second, third tooth plate respectively, and drives first, second, third tooth plate and alternately mesh with central gear.
Stake mechanomotive force head height speed reducer described in the utility model, wherein, described first eccentric segment and the 3rd eccentric segment equal in length, and the second eccentric segment length is first eccentric segment and the 3rd eccentric segment length sum; Described first tooth plate equates with the 3rd tooth plate width, and the second tooth plate width is first tooth plate and the 3rd tooth plate width sum.
Stake mechanomotive force head height speed reducer described in the utility model, wherein, described second tooth plate further comprises two identical tooth plates.
Stake mechanomotive force head height speed reducer described in the utility model, wherein, first, second, third eccentric segment of described bent axle is connected by bearing with first, second, third tooth plate respectively.
Stake mechanomotive force head height speed reducer described in the utility model owing to adopted four crankshaft structures that input power is shunted, has reduced the load of bearing, has improved the working life of bearing and complete machine.Simultaneously, by the quadruplet phase difference is the structural type of 180 ° crank-driven, bent axle radial effect power is distributed in the same plane, effectively balance the centrifugal force that high speed rotating produced, eliminated to greatest extent because the influence that machining deviation produces, solve the dynamic equilibrium problems of driving component, improved transmission stability greatly, thereby also improved the bearing capacity and the anti-overload ability of this equipment.
