Embodiment
Below in conjunction with instantiation and accompanying drawing, the present invention will be further described.
Fig. 1 is the fundamental diagram of one embodiment of the invention, Fig. 2 is the differential design sectional drawing of one embodiment of the invention, a kind of differential speed type dual-reamer sludger provided by the invention, it comprises motor 9, reamer 8 and differential mechanism, wherein the follower (drive bevel gear 6 namely in the present invention) of motor 9 is fixedly connected with the differential carrier 3 of differential mechanism thus drives differential mechanism to operate, and 2 differential gears 1,2 of differential mechanism are connected with 2 reamers 7,8 respectively by reamer gear.In the present embodiment, for symmetric type bevel differential, symmetric type bevel differential comprises described differential carrier 3, differential carrier 3 is connected with the planet pin 5 of its inside, form planet carrier, respectively there is 1 planetary pinion 4 both sides of planet pin 5,2 planetary pinions 4 engage with described differential gear 1,2 respectively, contact points (in figure A and B), the planetary pinion 4 of planetary pinion 4 and differential gear are equal to the distance of differential mechanism rotating axis 5 with the contact points C of planet pin 5, be r, described reamer gear is bevel gear 10,11.
In this differential speed type dual-reamer sludger working procedure, motor 9 runs the rotating speed that produces and power reaches drive bevel gear 6(on symmetric type bevel differential and motor follower at first), drive bevel gear 6 drives symmetric type bevel differential to operate, by the adjustment of symmetric type bevel differential, the rotating speed that motor is exported and power delivery to bevel gear 10,11 place on the reamer of both sides, thus drive reamer 7,8 to carry out work.
Symmetric type bevel differential is a kind of planetary gears, and differential carrier 3 is connected with planet pin 5, forms planet carrier, because it connects together with electric drive bevel gear 6 again, pretends as driving link, if its angular velocity is ω
0; 2 differential gears 1 and 2 are as driven member, and its angular velocity is respectively ω
1and ω
2.A, B 2 are respectively the contact points of planetary pinion 4 and differential gear 1 and 2.Planetary center is C, A, B, C 3 distances to differential mechanism rotating axis are r.
When planetary pinion 4 just revolves round the sun around symmetric type bevel differential spin axis in company with planet carrier, the peripheral velocity being in A, B, the C 3 in same radius r is equal, is ω
0r.So now ω
1=ω
2=ω
0, differential mechanism does not play differential action, and half axis angular rate equals the angular velocity of differential carrier 3.
When planetary pinion 4 is except revolution, also around himself planet pin 5 with angular velocity omega

Above formula is the identical symmetric type bevel differential kinetic characteristic equation of two-semiaxle gear diameter.The rotating speed sum of left and right sides differential gear equals the twice of differential carrier rotating speed, has nothing to do with planetary pinion rotating speed.In the reamer working procedure of dredger, by planetary pinion with corresponding rotating speed rotation, both sides reamer can be made in earth, to carry out cutting with different rotating speeds and to roll and fricton-tight operation.
Above embodiment is only for illustration of design philosophy of the present invention and feature, and its object is to enable those skilled in the art understand content of the present invention and implement according to this, protection scope of the present invention is not limited to above-described embodiment.So all equivalent variations of doing according to disclosed principle, mentality of designing or modification, all within protection scope of the present invention.
