一、前言汽车起重机双桥转向摇臂机构是空间机构,设计时,可将它简化为平面机构处理,因此,必然带来机构简化误差。但误差大小和允许误差如何,怎样简化可以减少误差,以及误差对机构转角偏差的影响等至今缺乏探讨。本文在研究了空间和平面摇臂机构的解析设计法和明确提出对空间摇臂机构的设计要求的基础上,通过QY40汽车起重机的实例,对空间和平面摇臂机构的转化误差和健角偏差进行计算和分析。
First, the foreword Truck crane Shuangqiao steering rocker mechanism is a space agency, design, it can be simplified as a plane body processing, therefore, inevitably bring about institutional simplification error. However, the error size and allowable error how, how to simplify can reduce the error, as well as the error on the body angle deviation so far lack of discussion. Based on the analysis of the analytical design method of space and plane rocker mechanism and the design requirement of space rocker mechanism, the paper analyzes the conversion error and angular deviation of space and plane rocker mechanism through the example of QY40 truck crane, Calculate and analyze.
