Belt Grinder 2x72 Knife Making Include Idler, Tracking, and Drive wheels (As Shown in pictures). Search 2" x 72" Belt Grinder from Pulley-Wheel on youtube. Steel Chassis is made from 10, and 6 mm thick steel. 30 mm x 30 mm solid steel arm.
2 x 50 mm Idler wheel, 1 x 80 mm Tracking wheel, and 1 x 100 mm Drive wheel. Drive wheel is mounted on a 20 mm diameter steel axle which also holds a 70 mm diameter belt pulley wheel. From experince this is the most flexible mounting method, because it allows for mounting the motor anywhere (even under the table) to protect it from grinding dust.
Tracking Wheel is attached to an arm that can be continously regulated (Spring tension is adjustable via a knob). Arm Rest 10 x 16 cm. We use the heaviest duty bearings 6302 RS which has a 15 mm bore, but we use 15/12 mm reduction spacer to allows for the use of M12 bolts for mounting. The structure is extremely solid, and the weight of the machine is about 20 kg. The machines allows for the use of belts up to 2200 mm in length (86 inch).Please take a look at the CAD screen shots that shows possible ways to mount your motor. You can acheive different speeds by having step pulley attached to the motor. Belt surface speed is usually somewhere around 1000 meter/min.
Therefore if you will use a 2850 rpm motor, you should think of using a step pulley of 60, 80, and 100 mm in diameter. The pulley on the drive shaft is 60 mm diameter, and the drive wheel is 110 mm in diameter. Therefore with this size step pulley you will achieve 1000, 1350, and 1650 meter/min surface speeds.If you will use a 1450 rpm moto then you should have almost twice as large diameter step pulley. Machine will be sent out next day as we have to order a courier.
