螺旋输送机的头节装置(止推轴承装置)和尾节装置(平轴承装置)一般采用滚动轴承。由于螺旋叶是通过中间轴连接在一起的,在设备运转中,其同轴度误差引起的振动加剧了止推轴承装置和平轴承装置损坏,特别是离驱动装置较远的平轴承装置(图1),其单列向心球轴承和尾轴极易磨损,更换频繁,且检修十分不便。 Screw head knuckle device (thrust bearing device) and the tail section device (flat bearing device) generally use rolling bearings. Due to the helical blades being connected together via the countershaft, vibrations due to their coaxiality errors during operation of the device exacerbate the deterioration of the thrust bearing arrangement and of the plain bearing arrangement, in particular of a flat bearing arrangement far from the drive arrangement ), Its single radial ball bearings and tail shaft wear easily, frequent replacement, and maintenance is very inconvenient.
