摘　　要：分析了涡旋压缩机动涡旋盘所受的各种气体力及力矩,得到了一个周期内气体力和力矩随曲柄转角变化的规律。并建立了小曲拐防自转机构受力模型,计算了小曲拐轴承的最短使用寿命。在此基础上提出了三维限位防自转机构,对其进行了受力分析和最短使用寿命计算,并与小曲拐防自转机构最短使用寿命进行对比,结果表明三维限位防自转机构最短使用寿命比小曲拐防自转机构长,是一种良好的新型防自转机构。The gas forces and torques suffered by the orbiting scroll of the scroll compressor are analyzed and the variation rule of the rotation angle with the gas force and torque in a cycle is obtained, the stressing model of the small crank of the anti-rotation mechanism is established, and the shortest service life of the small crank bearing is calculated. On this basis, a three-dimensional limit anti-rotation mechanism is proposed, the suffered stresses are analyzed, and the shortest service life is calculated and compared with the shortest service life of the small crank anti丒iDtation mechanism. The results show that the shortest service life of the three-dimensional limit antirotation mechanism is longer than that of the small crank anti-rotation mechanism and it is a good novel anti-rotation mechanism.
