摘要
组合机床是由大量的通用部件和少量专用部件组成的工序集中的高效率专用机床。它能够对一种(或几种)零件进行多刀、多轴、多面、多工位加工。在组合机床上可以完成钻孔、扩孔、铣削磨削等工序,在实际生产中广泛应用,生产效率高,加工精度稳定。
本文主要针对专机上主轴箱部分,进行装配设计以及计算。主轴箱是工序集中的、高效的组合机床的重要的专用部件之一,是用于布置(按所要求的坐标位置)机床工作主轴及其传动零件和相应的附加机构的。它通过按一定速比排布传动齿轮,把动力从动力部件——动力头、动力箱、电动机等,传递给各工作主轴,使之获得所要求的转速和转向等。绘出图纸,明确计算,通过设计的过程最终得到主轴箱精确的齿轮传动系统,和具体的分布情况,使之符合加工要求。

Abstract
Machine Tool is a small number mon parts and processes focus on specific parts of position of the high efficiency of machine tool. It can one (or several) components for multi-knife, multi-axis, multi-faceted, multi-bit processing. Machine tool can be done bination drilling, reaming, milling, grinding, etc. Processes, widely used in actual production, high efficiency, stability and precision.
This article will focus on the spindle box part of the plane, to assembly design puting. Headstock is a process focused, bination of machine-ponents important one is used for layout(coordinates according to the required location) machine tool spindle and its ponents and the corresponding additional institutions. It is arranged by a certain geat ratio, the power from the power unit-power head, power boxes,motors,etc., passed to the work spindle, and thus obtain the required speed and steering. Draw drawings, clear terms, through the design process finally be precise pear box drive shaft, and the specific distribution to conform to process requirements.
