摘　　要：针对直驱涡旋压缩机动、静涡旋盘安装相角无法调整的问题,提出了一种基于摆角电机的直驱涡旋机相角调整方法。首先,提出了基于摆角电机的直驱涡旋机架构方案,分析了动涡旋盘型线特点及其相角调整的机理;然后,提出了动涡旋盘相角调整的方法,即通过动涡旋盘运行轨迹上任意3个非重合点,推算出了动涡旋盘的平动轨迹圆半径,在确定动涡旋盘的调整相角方向后,进行了相角调整寻优;最后,搭建了直驱涡旋压缩机相角调整的实验平台,对上述方法的可行性进行了验证。实验结果表明:当动涡旋盘的调整相角为-4°时,推算的平动轨迹圆半径达到最大R=4.686 mm,理论计算平动轨迹圆半径r=4.721 mm,两者之间相对误差为0.73%。研究结果表明:利用该方法可有效调整涡旋压缩机动涡旋盘的相角。Aiming at the problem that the installation phase angle of the direct drive scroll and the fixed scroll could not get adjusted,a method of adjusting the phase angle of direct drive scroll based on swing angle motor was studied.Firstly,the architecture of direct drive scroll based on swing angle motor was proposed,the characteristics of the movable scroll profile and the mechanism of phase angle adjustment were analyzed.Then,the method of adjusting the phase angle of the orbiting scroll was proposed,that was,the radius of the orbiting scroll's translational trajectory circle was calculated through any three non-coincident points on the orbiting scroll's running trajectory,and the phase angle adjustment was optimized after confirming the direction of the adjusting phase angle of the orbiting scroll.Finally,an experimental platform for phase angle adjustment of direct-drive scroll compressors was built to verify the feasibility of the above methods.The experimental results show that,when the adjusted phase angle of the orbiting scroll is-4°,the calculated translational trajectory circle radius reaches the maximum R=4.686 mm,and the theoretical translational trajectory circle radius r=4.721 mm.The relative error between the two is 0.73%.The research results show that this method can effectively adjust the phase angle of the orbiting scroll compressor.
