真空热处理炉能否好用的关键是工件传送机构运动必须可靠，能够满足动作要求和运动的时间要求。这是设计真空炉应考虑的中心思想。本文首先分析用于真空热处理淬火炉中料筐（装工件的筐）的各种传动机构的优缺点，并综合国外最近生产的淬火炉工件传动机构，我们认为气压传动很有发展前途。气压传动结构简单，没有污染，成本低。运动速度快．运动速度可以无级调速．而且活塞在开始运动和终了端有缓冲，无噪音， 运动非常可靠。由于气动元件现在已经进行标准化生产带来成本低。质量好。所以本文 对于气动传动元件选择，运动时活塞推拉力的计算进行比较详细的研究讨论，并根据实 验结果写出计算公式。
Vacuum heat treatment furnace can be easy to use the key is the workpiece transfer mechanism movement must be reliable to meet the movement requirements and movement time requirements. This is the design of vacuum furnace should be considered the central idea. This paper first analyzes the advantages and disadvantages of the various transmission mechanisms used in the vacuum heat treatment of quenching furnaces (baskets of workpieces), and integrates with the recently produced quenching furnace workpiece transmission mechanism in foreign countries. We think that the pneumatic transmission is promising. Pneumatic drive structure is simple, no pollution, low cost. Fast movement. Speed can be stepless speed regulation. And the piston in the beginning of exercise and the end of the buffer, no noise, exercise is very reliable. As the pneumatic components have now been standardized to bring the low cost. Good quality. Therefore, this article for the selection of pneumatic transmission components, the calculation of piston push-pull during exercise more detailed discussion, and write the formula based on experimental results.
