Rubber extrusion sheet press gearbox
Large capacity rubber extrusion sheet press gearbox
The main gearbox, namely the bipyramid twin screw extruding and sheeting machine group (for short Extruding 8^1 Sheeting Machine) is a kind of high precision, heavy duty and tooth-flank hardened product matched for the downside assistant machine of the internal batch mixer, which is comprised of the gearboxes for the extrudering and the sheeting machine. There are five types of driving of this main gearbox, and left and right driving kinds for each type.
The gearbox of extruder (type A) includes left and right sets of gear boxes (a cylindrical gearbox and a bevel gearbox respectively), and one of the bevel gearbox is connected to motor through resilient coupling with its input shaft. Input shafts of the two bevel gearboxes are connected by flexible coupling. Both bevel gearboxes are reversed the rotation director by bevel gears, and reduced the speed by parallel gears, and finally the speed of two output shafts Ihollow shaft) get the same but rotate on opposite directions and drive the meshing thread rod respectively.
The gearbox of extruder (type B) is connected to the motor by resilient coupling, and through three stages of gears reducing the speed, the output shaft (hollow shaft) gets the output speed. As the rotor shaft of the extruder has been assembled into the hollow shaft, the movement and power are transmitted to the rotor shaft through hollow shaft, after that, through a pair of bevel gearboxes, it drives the meshing thread rod of the extruder.
The input shafts of gearboxes of extruder (type C) and sheeting machine Type D) are connected to motors through resilient couplings. Reduced by three stages of parallel gears, the rotation speed at the output shaft I is n1, and then the power is distributed by a gear between two output shafts with has the same teeth number, shaft 11 gets the same rotation speed with shaft I . These two output shafts are connected to rotor shafts of the working machine through flexible couplings, thus the two rotor shafts work under same rotation speed and opposite directions.
The input shaft of geabox of sheeting machine (type E) is connected to the motor through resilient coupling. By three stages' reduction, the output shaft gets it speed, this speed is transmitted to the rotor shaft of sheeting machine through crowned teeth coupling.
1.The material of the gear is high strength alloy carburizing steel material.
2.The gear goes through carburizing and quenching gear grinding.
3.The gearbox can bear larger axial thrust.
4.Distribution box goes through gear cutting by CNC gear hobbing machine and nitrogen treatment.
5.The gearbox all use high-quality skeleton oil seal, and the high speed shaft use double seal with oil seal and mechanical seal.
Rubber machinery is a machine used to manufacture various rubber products such as tires, including general rubber machinery, tire machinery, and other rubber product machinery. General rubber machinery is a machine for preparing rubber or semi-finished products, including raw material processing machinery, rubber refining machines, extruders, calenders, curtain canvas pretreatment devices and cutting machines. Mixers are divided into two types, open and closed. The open-type rubber mixing machine is mainly used for rubber refining, tablet pressing, plastic breaking, plastic mixing and mixing. Closed-type rubber mixers are mainly used for plasticizing and mixing of rubber. It has one more mixing chamber than open-type rubber mixers.
