Shaftless screw conveyor is driven by the motor cycloidal needle reducer operation, relying on the mechanical seal shaft and shaftless screw body on the connection disk drive to rotate the spiral, when the material into the U-groove above the feed port, shaftless conveyor will rotate through the drive shaft to make the material along the spiral down, so that the material from the U-groove below the discharge port. Compared with the traditional shaftless screw conveyor, shaftless screw conveyor adopts the design of no central shaft and uses the integral steel screw with certain flexibility to push the material, so it has the advantages of strong winding resistance.
Shaftless screw conveyor is mainly composed of drive device, head assembly, housing, shaftless screw body, slot liner, feed port, discharge port, cover (optional), base, etc.
Shaftless screw conveyor structure
Drive device: Use cycloidal pinwheel reducer or shaft mounted hard tooth gear reducer, the design should be as far as possible to drive the device at the end of the discharge port, so that the helix in the running in the tension state. The head is equipped with a thrust bearing, which can withstand the axial force generated when conveying materials.
Shaftless screw conveyor drive device
Case: The case is U-shaped or O-shaped, and the upper part of the rainproof cover is made of stainless steel or carbon steel or fiberglass.
The working principle of shaftless screw conveyor
Shaftless screw conveyor material transportation is sliding by rotating blades, the direction of transportation determines the left and right rotation of the spiral blade and its rotation direction, so according to the need for one-way and two-way transportation, but also multi-point loading. It can be installed horizontally or tilted at a certain Angle, and the material enters the helix from the feed port, and the material is loaded from the discharge port through the rotation of the spiral or enters the press and is loaded after being pressed and dehydrated. The conveyor length L is selected by the user, the power drive device adopts double cycloidal gear reducer or worm gear helical gear reducer, it can be installed in the conveyor entrance end (push screw) can also be installed in the exit end (pull screw), the U-shaped groove of the equipment at the bottom, with anti-wear protective bushing, it is selected according to the different conveying materials.
