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