高速重载的各种宽斜齿轮,例如船用大型减速箱齿轮,在承载运转中产生扭转变形、热变形及离心力变形的情况下,要求齿轮在齿宽全长上均匀接触。为此,在精加工齿轮时,需要在齿向上进行修整,其修整量在节圆处为5～30微米。本文所述系统,是在线自动控制的大型齿轮高精度齿向修整的剃齿系统,它比以往常用的依据接触斑点来修整的方法,更为精确省时,能保证1～3微米的精度。本系统由下列三大部分组成(图1)。 Various widely used high-speed heavy-duty helical gears, such as marine gearboxes with large gearboxes, require torsional deformation, thermal deformation and centrifugal deformation during bearing operation, requiring uniform contact of the gear over the entire tooth width. For this reason, when finishing the gear, the tooth needs to be trimmed upward, and the dressing amount is 5 to 30 microns at the pitch circle. The system described herein is a large-scale, gear-automatic, toothed gear shaving system that is automatically controlled on-line and is more accurate and time-saving than conventional methods of trimming contact spots to ensure 1 to 3 micron accuracy. The system consists of the following three major components (Figure 1).
