摘要
锁紧盘属于典型的过盈联接装置,作为一种先进传动方式,具有装配拆卸简便、承载能力强等优点,在机械工程领域有着广泛的应用。本文基于传统设计方法,以MW级风电锁紧盘为例,建立锁紧盘的力学模型,得到各过盈结合面接触压力之间的关系表达式,推导出推进压力与过盈量的函数表达式,进而确定螺栓扭紧力矩与过盈量的函数表达式,提出一种考虑螺栓扭紧力矩的锁紧盘新型设计方法;通过有限元仿真计算,两种方法最大误差仅为5. 12%,验证本文设计算法的可行性;该设计方法进一步拓展和补充了过盈联接基础设计理论,利用参数化运算,实现锁紧盘的系列化设计,有助于实现传统机械设计向智能化创成设计的升级转变。
Shrink disk is a typical interference fit device.As an advanced transmission mode,it is easy to assemble and disassemble,and its bearing capacity is heavy.Shrink disk is widely used in mechanical engineering.In this work,taking shrink disk of MW grade wind turbine as an example,mechanical model of shrink disk is established based on the traditional design method,the expression of contact pressure between interference joint surfaces is obtained,the function expressions of between thrust pressure and interference,bolt torque and interference are determined,a new design method of taking bolt torque into account of shrink disk is proposed.The maximum error of the two methods is only 5.12%,which verifies the feasibility of the proposed algorithm.This design method further expands and supplements the basic design theory of interference connection.It can realize the series upgrade of shrink disk and complete by parametric calculation.It is helpful to realize the upgrade transformation from traditional mechanical design to intelligent generation design.
