1. The screw shaft and the suspension bearing, the head and the tail shaft are all connected by the tongue type. The installation and disassembly do not need axial movement, and the maintenance is convenient. , the mandrel is long, the hanging is less, and the fault point is less;
2, the use of variable diameter structure, increase the volume of the hanging bearing, to avoid contact between the hanging bearing and the material, the life of the hanging bearing can reach more than two years;
3. The transmission parts are all connected by floating connection. The suspension bearing is a universal joint structure, so that the spiral body, the hanging bearing and the tail assembly form an integral spiral floating body, which can freely rotate and avoid with the conveying resistance within a certain range, without jamming. Do not block the material;
4. The head and tail bearing housings are all outside the housing. All bearings adopt multi-layer sealing and sealing technology, and the bearing has a long service life.
