Abstract
The utility model relates to a two-stage three-ring speed reducer utilizing metallic flexible ring load-portfolio vibration-damping completely-balanced inertia force, which changes a middle ring board and quality distribution of two-side ring boards of a present three-ring speed reducer, and employs a metallic flexible load-portfolio ring as a load-portfolio vibration-damping device. The utility model has the advantages of high transmission efficiency up to about 93 percent, appreciable load-portfolio effect. The load-distribution heterogeneity coefficient K<p> is reduced below 1.1, the chest body vibration is appreciably reduced, and especially radial vibration acceleration and vibration effective speed of a bearing seat of an output shaft are both appreciably reduced.
Description
The utility model belongs to a kind of new gear transmission device.
Because the research history of three-ring gear reducer is shorter, as a kind of new things, the problem of three-ring gear reducer existence at present mainly contains:
1. in three-ring gear reducer, each internal tooth ring plate all is equivalent to the connecting rod in the double crank mechanism, is driven by input shaft and does the translation of high speed curve, and the inertial force direction is cyclically-varying, makes mechanism produce shock and vibration.
2. owing to three identical internal tooth ring plates are 120 ° of phase differences runnings side by side, inertial force is balance in theory, but inertia couple is unbalanced.Especially when high speed turned round, inertia couple just became the main root that three-ring gear reducer produces bigger vibration.Three-phase existed constraint and dead point to impact each other between the double crank mechanism of 120 ° of phase differences, cause additional impact dynamic load owing to make alignment error, caused body vibration and noise.
3. make and alignment error owing to inevitable, and the part stress distortion, cause evenly stand under load of three identical internal tooth ring plates during work, seriously influence giving full play to of its power dividing type structural advantages.
All confirm and find from present theory analysis, experimental research document and practical application, the three-ring gear reducer vibration is generally bigger, and along with prime mover rotating speed improves, velocity ratio increases and transmitted power increases and aggravates, can cause internal tooth ring plate fracture, bearing heating to lose efficacy when serious, shortened complete machine working life, reduced the superiority of three-ring gear reducer, seriously influenced the actual of three-ring gear reducer and apply.
The purpose of this utility model is to have proposed a kind of novel full balance of shaking force, all carry the two-stage three-ring gear reducer of vibration damping, has solved the above-mentioned key issue that three-ring gear reducer is applied that influences.
The purpose of this utility model is achieved in that the transmission of employing two-stage, and the one-level transmission is a column gear transmission, and the secondary transmission is the few tooth difference transmission of three-ring type.The one-level transmission is used to reduce rotating speed, the increase complete machine velocity ratio of three-ring gear reducer eccentric shaft, and realizes that twin shaft drives to overcome the dead point.Phase difference in the middle of the secondary transmission is adopted between ring flat-plate and the both sides ring flat-plate off-centre is 180 °, and the quality of middle ring flat-plate is the twice of identical two both sides ring flat-plate quality, thereby realizes the inertial force of three-ring gear reducer and the complete equilibrium of inertia couple.Adopt a kind of metallic elastic ring as load-balancing device, be installed at respectively between the outer ring and bearing saddle bore of one-level input shaft and secondary output shaft block bearing, the distortion that elasticity is all carried ring is floated the external gear on secondary output shaft and the one-level input shaft, alignment error and transmission distortion are made in compensation, thereby improve the dynamic performance of three-ring gear reducer, realize all carrying and vibration damping.
Owing to adopt such scheme, realize the complete equilibrium of the inertial force and the inertia couple of three-ring gear reducer, and improved the dynamic performance of three-ring gear reducer, realize all carrying and vibration damping.These facility have higher transmission efficiency, can reach about 93%; The load equalization effect is obvious, and load distribution nonuniformity coefficient KP reduces to below 1.1; The casing vibration obviously reduces, and especially the radial vibration acceleration of output shaft bearing seat and vibration effective velocity all obviously reduce.
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is vertical profile drive mechanism figure of the present utility model.
Fig. 2 is three ring drive part three-dimensional structure diagrams of the present utility model.
Among the figure: 1. the eccentric input shaft 2. low speed output shafts of high speed 3. internal tooth ring plates (middle ring flat-plate and both sides ring flat-plate) 4. export external gear 5., 6. shunting fixed shaft external gear 7. driving gears 8. one-level input shafts 9. output shaft elasticity all carry the ring 10. input shaft elasticity all carry ring.
In Fig. 1, Fig. 2, the transmission of three-ring gear reducer secondary is by two eccentric input shafts 1 of high speed, and 2, three internal tooth ring plates 3 of low speed output shaft (ring flat-plate and two both sides ring flat-plates in the middle of a slice, the thickness of middle ring flat-plate is the twice of both sides ring flat-plate thickness) and external gear 4 constitute.For dead center position, increase velocity ratio and the reduction secondary input shaft rotational speed that overcomes eccentric input shaft, the one-level transmission adopts shunting fixed shaft external gear 5,6 to drive two eccentric input shafts respectively, and external gear 5,6 is then driven by the driving gear on the one-level input shaft 7.Three internal tooth ring plates all are meshed with external gear 4.Be equipped with between the output shaft 2 of three-ring gear reducer and one-level input shaft 8 pedestal bearing outer races and bearing saddle bore that output shaft elasticity is all carried ring 9 and input shaft elasticity is all carried ring 10.
