Technical field
The present invention relates to a kind of special reduction gear of plate bending rolls, especially a kind of Combined speed reducer for plate-rolling machine of low-speed heave-load of 3 input output on single points.
Background technique
Along with the high speed development of the industries such as the energy, chemical industry, the demand of the key equipments such as process equipment especially pressurized container is also increased day by day.Overwhelming majority pressurized containers are by the processing of curling sheet metal, and plate bending rolls is that sheet metal is carried out to bending, curling key equipment, and powerful plate bending rolls need to configure that to transmit speed ratio large, the special reduction gear that transmitting torque is large.
At present, speed reducer for plate bending rolls is all generally the speed reducer that adopts single input mode, such speed reducer all adopts the man-to-man mode of operation of directly driving, adopt a heavy-duty motor directly to drive the input shaft of speed reducer, by speed reducer, after multi-stage speed-reducing, directly by output shaft, drive plate bending rolls, the plate bending rolls special reduction gear of this structure, general volume ratio is larger, transmit speed smaller, transmitting torque is less, should not be for to super thick, super wide, the sheet metal that particularly hardness is higher carries out stample fiber.
Summary of the invention:
The object of the invention is to: for the current speed reducer for plate bending rolls, especially directly drive the volume that the plate bending rolls speed reducer of mode of operation exists large, transmit speed little, transmitting torque is little, should not be for to super thick, super wide, the sheet metal that particularly hardness is higher carries out the problem of stample fiber, and a kind of new Combined speed reducer for plate-rolling machine is provided.
The object of the present invention is achieved like this: a kind of Combined speed reducer for plate-rolling machine, comprise casing, output shaft and input gear axle, and it is characterized in that:
A) output shaft is fixed on casing by bearings, and output shaft is provided with output gearwheel;
B) three input gear axles that contain actuation gear are evenly distributed on the periphery of exporting gearwheel, described actuation gear and the engagement of output gearwheel, each input gear axle is fixed on casing by bearings respectively, and the input end of input gear axle is provided with external splines;
C) the planetary speed reducer assembly of three same sizes is positioned at the input end of input gear axle, the input end of planetary speed reducer assembly is provided with oil hydraulic motor, output terminal is inner spline housing, described inner spline housing docks with the external splines on described input gear axle, and the housing of planetary speed reducer assembly is fixedly connected on casing.
In the present invention: described planetary speed reducer assembly is two-stage planetary speed reducer.
In the present invention: have two input gear axles to be positioned in the plane parallel with bottom half.
In the present invention: described casing is divided into upper box and lower box, at grade, three described input gear axles lay respectively at upper box or lower box the separatrix of upper box and lower box and the medial axis of output shaft.
In the present invention: on upper lower box, be equipped with stiffening rib, one end starting point of described stiffening rib is distributed in output shaft and three input gear axle periphery casings.
In the present invention: on the corresponding casing of output shaft and each input gear axle Vertical direction, a vertical stiffening rib is at least set, two stiffening ribs that extend along directions of rays are set at least respectively on the corresponding casing of each input gear axle both sides
The invention has the advantages that: because prime deceleration adopts planetary speed reducer, especially adopt two-stage planetary speed reducer, final stage is slowed down and adopted actuation gear and export gearwheel, compact structure, volume is little, transmits speed ratio large; Owing to adopting the planetary speed reducer assembly of three same sizes to be uniformly distributed driver output gearwheel, greatly improved the moment of torsion of output shaft; Input end employing oil hydraulic motor due to planetary speed reducer assembly, makes speed reducer obtain soft drive, even if three planetary speed reducer assemblies exist machining error or assembly error, oil hydraulic motor also can be realized power reasonable distribution, and overload release channel is provided; Because casing is divided into upper box and lower box, the separatrix of upper box and lower box and the medial axis of output shaft make complete machine easy accessibility at grade; Upper lower box is provided with stiffening rib, can improve the bearing capacity of speed reducer.
