摘　　要：目前使用的支撑轮式转杯纺纱机的纺杯杆支撑装置的径向定位方法是用2对能自由转动的支撑轮沿轴线形成的契形夹缝来支承纺杯杆。此技术的优点是用低轴承转速实现高纺杯转速,降低了对轴承的要求并延长了轴承寿命。但在实际应用中,因为纺杯杆给支撑轮的压力太大,使得支撑轮的表面易磨损,因而介绍了一种纺杯支撑装置的改进方法,改进装置不仅能减小纺杯杆对支撑轮表面的压力,延长支撑轮寿命,同时也减小了纺杯杆的弯曲变形,提高纺纱系统的动态稳定性。At present, the actually radial positioning method of the advanced rotor spinning supporting device is to support the rotor pole using the wedge-shaped crack formed by two pairs of rotating support wheels which are along with the direction of axis. The advantage of this technique is to achieve high speed of the rotor by using low-speed bearing, thereby reducing the requirement of the bearing and prolonging its life-span as well. While putting this in real practice, the rotor pole applies too much pressure on the supporting wheels and this will result in the premature wear of the wheel＇s surface. This paper introduces a method to improve the rotor spinning supporting device, this improved device not only reduces the pressure on the wheel＇s surface and effectively prolong its life span, but also reduces flexural deformation of the rotor pole and increases the dynamic stability of the spining system.
