Description
Technical field
The utility model relates to a kind of speed reducer, the reamer speed reducer in especially a kind of cutter suction dredger.
Background technique
Along with boats and ships maximize, maximize in the harbour, navigation channel deep water drive dredging market continues flourish.Urban development and industrialization construction, land resources is rare, has brought bright prospects for enclosing sea (enclosing the beach) with making.The seaway construction brings new market for the dredging industry.Dredge the flourish of industry, country greatly develops the engineering ship construction and revitalizes maritime works's cause, and the demand of dredger is very huge.Cutter suction dredger accounts for more than 60% of domestic dredger total amount as very important ship type in the dredging vessel, has wide application market.
Generally to be useful on the long axis system reamer and to be used for minor axis with speed reducer be the speed reducer of reamer to reamer on traditional cutter suction dredger, the speed reducer that wherein is used for the long axis system reamer is operated in more than the water surface, minor axis is that the speed reducer of reamer then is operated in below the water surface, because reamer several meters or tens of meters work under water, task requires it can proper functioning in 0 ~ 65 degree scope, reamer for several meters or tens of meters work under water, generally all adopt minor axis system, be in the rotating speed height of speed reducer under water, output power and moment of torsion are big, tightness requires high, and need bear very big thrust, not only operating mode is abominable under water, and reliability requirement is also high, can proper functioning in 0 ~ 65 degree scope, therefore, how to solve under water can proper functioning at tens of rice speed reducer just become the technical bottleneck of development deep water river cutter suction dredger.
The model utility content
The purpose of this utility model is: at cutter suction dredger reamer speed reducer rotating speed height, output power and moment of torsion are big, and need bear very big thrust, reliability requirement is also high, not only operating mode is abominable under water, tightness requires high, and practical problem that can proper functioning in 0 ~ 65 degree scope, and the reamer speed reducer in a kind of new cutter suction dredger is provided.
The purpose of this utility model is achieved in that the reamer speed reducer in a kind of cutter suction dredger, comprises casing, input gear shaft, intermediate gear shaft, and intermediate gear, output gear and output shaft is characterized in that:
A) be seal case in the casing, in casing, an end of output shaft stretches out casing to output shaft by bearings; Two input gear shafts that are parallel to each other, two first intermediate gear shafts and two second intermediate gear shaft symmetric arrays are in the output shaft both sides, and input gear shaft one end stretches out casing;
B) be installed with first intermediate gear on first intermediate gear shaft, be installed with second intermediate gear on second intermediate gear shaft, fixedly mount output gear on the output shaft;
C) described input gear shaft and first intermediate gear engagement, first intermediate gear shaft and the engagement of second intermediate gear form two-way transmission branch road arranged side by side, second intermediate gear shaft in the two-way transmission branch road and the engagement of same output gear;
D) pass through on the input gear shaft of casing and the output shaft and be equipped with floating seal.
In the utility model: the lubrication system of speed reducer comprises lubricating pump and lubricating oil path, and described lubricating pump is driven by first intermediate gear shaft.
In the utility model: described two-way transmission branch road and output gear all adopt angular gear; Be provided with on-line monitoring lubricant oil in the lubricating oil path and contain water sensor.
Advantage of the present utility model is: owing to adopt two-way transmission branch road acting in conjunction arranged side by side that the double input form makes up in output shaft, two-way transmission branch road and output gear all adopt angular gear, can improve output power and the moment of torsion of output shaft; Because output shaft is supported in the casing by Sliding bush, also be provided with the thrust ring that is solidified as a whole on the output shaft, be provided with thrust bearing shell between the front/rear end of thrust ring and the casing, an end of output shaft stretches out casing, and output shaft can bear bigger radially torsion and end thrust; Contain water sensor owing to be provided with on-line monitoring lubricant oil in the lubricating oil path, in case seepage takes place, just can in time report to the police, in order in time repair, guarantee the speed reducer proper functioning.Compact structure of the present invention is convenient to safeguard.
