Abstract

The invention relates to a same-direction double-screw transmission with oil motors, and belongs to the field of plasticizing extrusion molding. The same-direction double-screw transmission is characterized in that two output gear shafts of the same-direction double-screw transmission are transversely parallelly arranged in the center of a transmission case, transmission gears on the output gear shafts are arranged in a front-back dislocation manner, and front ends of the two output gear shafts are used as driving shafts of double screws; two transitional gear shafts are respectively arranged on two sides of the output gear shafts in the vertical direction, a front transmission gear and a rear transmission gear are fixed onto each transitional gear shaft, the two front transmission gears of the two transitional gear shafts are simultaneously meshed with the transmission gear of one output gear shaft, the two rear transmission gears of the two transitional gear shafts are simultaneously meshed with the transmission gear of the other output gear shaft, and two input gear shafts are respectively in gear transmission with the two transitional gear shafts via the oil motors. The same-direction double-screw transmission has the advantages that the double screws can rotate in the same direction, torque born by each output shaft can be greatly increased, and radial force on the output shafts is balanced.

Description

technical field [0001] The invention relates to a co-rotating twin-screw transmission device using an oil motor, which belongs to the field of plasticizing extrusion molding. Background technique [0002] Usually, in the plasticizing molding process of heat-sensitive materials, the co-rotating parallel twin-screw plasticizing extrusion device is driven by a motor, and the screw is driven to rotate through a reducer and a distribution box. Due to the special requirements of the plasticization molding process of heat-sensitive materials, the screw needs to work at ultra-low speed and ultra-high torque. Restricted by the structural characteristics of the output shaft of the distribution box of the co-rotating parallel twin-screw plasticizing extruder, the axial dimension is very long and the machining accuracy is high. The mechanical transmission requires a huge reduction device and a complicated transmission chain. An oil motor-driven screw device with co-rotating parallel tw...
