Transmission system of high pressure double-roller extrusion mill

Abstract

The invention discloses a transmission system of a high pressure double-roller extrusion mill. The transmission system comprises a fixed shaft with a fixed axle center position, a movable shaft with a movable axle center position, a movable pressurization seat used for fixing the two ends of the movable shaft, a movable shaft gear and a fixed shaft gear respectively arranged on the movable shaft and the fixed shaft, and a synchronous gear pair used for driving the movable shaft gear and the fixed shaft gear to rotate in opposite directions at equal angular velocity, wherein the synchronous gear pair comprises a driving gear and a driven gear, which are mutually engaged; the movable pressurization seat comprises a hinge connecting end and a moment acting end, the hinge connecting end is fixedly arranged through a hinge connecting shaft, and the axial line of the hinge connecting shaft is a first line; the axial line of the driving gear or the driven gear engaged with the movable shaft gear is a second line; the first line and the second line are collinear. The transmission system can overcome the problem of rotating speed difference of two rollers caused by respective drive of two motors so as to further reduce the relative slippage probability of the rollers.

Description

technical field [0001] The invention relates to a transmission system of a high-pressure double-roll extrusion mill, belonging to the technical field of high-pressure grinding equipment. Background technique [0002] The main working parts of the roller press mill are two cylindrical rollers arranged in parallel, one of which rotates with a fixed axis, and the axis of the other roller can move during the rotation to adapt to the The unevenness of the material. The pressure between the two rollers of the high-pressure roller mill is usually 50-300 MPa, and the material can be rolled into a powder cake in an instant, and a certain external force is applied, and the powder cake becomes a powder. Because the material passes through the working space of the roller press wheel very smoothly, without impact, and the noise is very low, so the crushing efficiency of the high-pressure roller press mill is very high. [0003] The wear of the roller surface of the roller is the main l...

AI Technical Summary

Problems solved by technology

[0004] The present invention is aimed at the deficiencies of the prior art, and provides a transmission system for a high-pressure double-roll extrusion mill, which can overcome the gap between the two roller press wheels caused by the use of two sets of motors and reducers to drive the two roller press wheels respectively. There is still a difference in the speed of the roller, so as to further reduce the probability of relative slippage of the roller, so as to reduce the wear of the roller surface of the roller, that is, to reduce the maintenance cost of the high-pressure roller extrusion mill
