Abstract

The invention discloses a main drive gearbox of a twin-screw extrusion machine. The extrusion machine comprises the gearbox and a motor which are electrically connected; the gearbox adopts the transmission mode of primary shunting and secondary interflowing of a herringbone tooth gear pair; and the gearbox comprises a first output shaft, a second output shaft, a series bearing, an input shaft, a pull rod, a second shaft system, a third shaft system, a fourth shaft system, a fifth shaft system, a sixth shaft system, a first expanding sleeve adjusting mechanism and a second expanding sleeve adjusting mechanism. On the condition of given small central moment, when a certain rotation speed is input, two same rotation speed and torque with high rotation precision are output at the same time inthe same direction, and the transmission efficiency is twice that of a gearbox of the same specification.

Description

technical field [0001] The invention relates to the field of gear box manufacturing, and more specifically relates to a main drive gear box for a twin-screw extruder. Background technique [0002] At present, in the design and development process of the twin-screw extruder transmission system, the main contradiction is that the center moment of the two output shafts of the gearbox is limited by the center moment of the two screws, and must be precisely fixed. In order to make reasonable use of the limited space in the box, ensure the strength requirements of the gears, and solve the contradiction between large load and small space in the design of the distribution gear, it is necessary to optimize the combination of the distribution gear and so on. Therefore, it is necessary to make overall consideration, carry out targeted design, and on this basis, verify and analyze, and propose a set of programs with certain research and practical value, so that the design is more reason...
