Problems solved by technology

However, on the one hand, the cost of the traditional full CNC gear hobbing machine is expensive. On the other hand, when a single motor is used to drive the hob, the motor is too large, resulting in excessive weight of the hob shaft cantilever, and unbalanced force, which causes excessive deformation during processing and affects processing accuracy.

Abstract

Disclosed is a dual alternating current (AC) servo motor drive hob structure of a gantry type gear hobbing machine. A hobbing shaft is simultaneously driven by third and fourth AC servo motors to perform rotation cutting, stressing is more balance, the deformation is smaller, and processing accuracy is higher; during light load processing, a hob can be also individually driven by the third AC servo motor or the fourth AC servo motor; radial feeding is loaded in the middle of a sliding vertical column, the stressing condition is better, and the feeding is more stable. The dual AC servo motor drive hob structure is capable of improving dynamic characteristics of a gear hobbing module, improving the stressing balance condition of the hob, reducing machine tool vibration and improving processing accuracy.

Description

technical field [0001] The invention belongs to the field of gear cutting and processing equipment, and in particular relates to a hob structure driven by double AC servo motors of a gantry type gear hobbing machine. Background technique [0002] As we all know, gears are the most basic mechanical transmission components, which are in great demand and widely used. The gear machine tool is recognized by the machine tool industry as one of the products with the highest technical content, the most parts and the most complex structure. But my country's gear manufacturing machine tool industry has been in an embarrassing situation for a long time. Today, the mechanical processing level of developed countries such as Europe, America and Japan is constantly improving rapidly, while domestic machine tool manufacturers are relatively backward in technology, start late, and generally lack independent innovation capabilities and key and core technical support. Today's domestic gear h...
