Optional accessories include tapered bushing kits, screw conveyor flanges, screw conveyor drive shafts, belt guards, motor mounts, backstops and more. Screw conveyors are used in a variety of applications where moving bulk material horizontally or vertically is required. Applications where screw conveyors are utilized are: aggregate and cement agriculture, grain, mining, water, wastewater and more.
The screw conveyor gearbox mounts on the trough end of a screw conveyor. We offer a variety of gear ratios and sizes of gear boxes as well as screw conveyor flanges and drive shafts. Simply add a screw conveyor flange. The screw conveyor flange includes mounting hardware – in this case 4 bolts and washers.
Don't forget, we offer a belt guard to be used in this application as well as electric motors to drive the gearbox. Our Shaft mounted Gearboxes can be mounted horizontally or vertically as shown making integration for screw conveyor applications simple.
Don't forget: we sell Worm Gearboxes, Motors, Motor controls and more.Please conact us, if you have any questions.
The primary drive shaft typically contains a stationary electromagnet which is fixed with a flange or torque tab. A rotor is fixed to the primary driving shaft with a key or other connection. Next, an armature is riveted to a flat spring. The flat spring is then riveted or screwed to a hub, or in this case, a pulley, which is then connected to a secondary shaft with a belt.
When a DC voltage is applied to the electromagnet coil a magnetic field is created. The magnetic circuit passes through the clutch rotor and armature. The force is large enough to deflect the flat spring and the armature is pulled across a small air gap into the rotor face. The friction between the rotor and armature allow the driving shaft and armature to rotate at the same speed.
You'll usually find at least two escalators alongside each other. One going up and the other going down. They can extend from multiple levels. Sometimes to save space, they'll be arranged in a crisscross pattern. But the layout will change depending on the needs of the place. Some escalators might need to be longer or shorter depending on the height of the next floor.
Maybe they'll need to be wider to fit more people, or several escalators might need to be right next to each other. Sometimes stairs are in the middle for those that want to walk.
Let's just focus on one of the steps as it comes down. You can see what would happened at this bottom wheel was just a little bit higher, the step would no longer be flat.
The same thing happens once we get back to the top here. The escalator motor is usually up at the top, it has to move this axle and two big gears that pull the step chain.
