Abominable based on trailing suction hopper dredger dredge pump gear box operating mode, overloading ratio is large, power is large, and rotating speed is high, and moment of torsion is large, reliability requirement is high, at present the reduction gear box on drag suction dredger is generally single-input single-output or the single output of double input, although the single output of double input can be according to the bearing capacity of the load variations regulating tooth roller box of dredger,, no matter adopt which kind of form, basically all have the reduction gear box of single transmission ratio.
Summary of the invention
The object of the invention is to: have the practical problem of single transmission ratio for the reduction gear box on present drag suction dredger, a kind of compact structure is provided, have simultaneously the gear-box that Dual-speed-ratio slows down.
The object of the present invention is achieved like this: a kind of trailing suction hopper dredger dual-speed-ratio speed reducer, comprise casing, input shaft, actuation gear, output gear and output shaft, one end of parallel input shaft and output shaft stretches out casing, and by bearings in casing, it is characterized in that:
A) a large actuation gear of fixed installation and a small drive gear on the input shaft, by bearing, a little output gear and a large output gear are installed on output shaft, wherein, small drive gear and large output gear engagement, large actuation gear and the engagement of little output gear;
B) external splines cover of fixed installation on the output shaft between big or small output gear, be respectively equipped with the external splines boss that is solidified as a whole on size output gear opposing side, the external splines cover that is fixedly mounted on output shaft is identical with external splines boss radius on big or small output gear, and profile of tooth is mated;
C) external splines that is fixedly mounted on output shaft puts the inner spline housing that is provided with coupling, and the outer wall of inner spline housing is provided with the annular fork slot of one closure, and shift fork drives inner spline housing by fork slot and slides on spline housing and external splines boss outside;
D) inner spline housing of slip or independent and external splines cover engagement, or the while overlaps with external splines and the external splines boss of one end meshes.
In the present invention: described large small drive gear and big or small output gear are angular gear.
In the present invention: the end of described input shaft is provided with pneumatic clutch; Described shift fork is the gas control shift fork.
In the present invention: trailing suction hopper dredger is comprised of lubricating oil bath, lubricating pump, oil leab, oil leab distributor and filter with the lubrication system of dual-speed-ratio speed reducer, and oil leab extends to each bearing.
The invention has the advantages that: owing to being provided with shifting fork gear-shifting mechanism on output shaft, can be trailing suction hopper dredger realizes Dual-speed-ratio output with speed reducer, changed existing trailing suction hopper dredger with speed reducer can only the single transmission ratio idea; Pneumatic clutch is set on input shaft due to the present invention; Shift fork is the gas control shift fork, makes gear-box more convenient to operate; Because lubrication system is delivered to each bearing by oil leab with the lubricant oil of cleaning, guarantee their reliable operations.Compact structure of the present invention is easy to maintenance.
