设计简介
摘 要
本次设计对象是竹材旋切机的液压系统。首先简要介绍了竹材旋切机的组成及其工作原理，其次对该液压系统负责的竹材旋切机的进给运动进行了设计。本设计在对液压进给系统的设计过程中，先进行了总体方案设计。在选择液压的控制回路的时候，在对各个回路进行了对比后我选择了进油口节流调速回路；确定了基本回路后，又确定了液压系统的传动形式，由于开式系统所具有的系统简单和散热条件好等优点，所以把传动系统确定为开式系统。在拟定液压系统原理图后，对液压元件及辅件进行了设计、选择，并对其进行校核。经过计算后液压缸选定为80毫米的液压缸，液压泵选定为叶片泵，根据系统工作的最大功率我选择的电动机为YB-A9B-L三相异步电动机。在确定泵后，又对其他的元件及辅件进行了合理的选择，最后确定各种元件后,进一步完成了我的设计题目。关键词：竹材，旋切机，液压系统，液压传动
Design on Hydraulic System of Bamboo Veneer Peeling
Abstract:The graduation project is bamboo peeling machine hydraulic system. First of all, briefly introduced the composition of bamboo peeling machine and its working principle, followed by the hydraulic system is responsible for the peeling machine of Bamboo to the movement into the design. The design of the hydraulic drive system in the design process, the first overall program design. In the selection of the hydraulic control circuit in all the time, in contrast to all carried out after the loop speed control loop, I opted for cutting into the oil port speed loop; unloading loop with I chose the manual four-way valve 2 unloading of the loop; pressure loop, I chose a one-way valve controlled by fluid pressure of the loop. Fundamental loop defined after a hydraulic system to determine the form of the drive, open the system as a result of the system with simple and good thermal conditions, etc., so as to open the transmission system. In the preparation of schematic diagram of hydraulic system, the hydraulic components and accessories for the design, selection, and check them. After calculating the selected after the hydraulic cylinder 80 mm hydraulic cylinder, hydraulic pump selected for the gear pump, in accordance with the system I chose the ma×imum power for the motor line YB-A9B-L three-phase asynchronous motor. In determining the pump after the other components and accessories for a reasonable choice, after the finalization of the various components, and further to complete the design of my subject.
