1. The first is the speed ratio, which is simply understood as the multiple of the speed reduction. Speed ratio = motor speed ÷ reducer output speed, which directly determines the running speed of the slitting machine. High-speed film slitting machines are equipped with small speed ratio reducers to ensure sufficient speed; heavy-duty paper tube and thick material slitting machines are equipped with large speed ratio reducers to reduce speed and amplify torque to meet heavy-load cutting needs.
2. The second is torque, which determines the cutting power of the reducer. The greater the torque, the stronger the cutting resistance and the higher the load capacity of the equipment. When processing thick materials, hard materials, and large coiled materials, a high-torque reducer must be selected, otherwise there will be inability to cut and stalling. For light materials, regular torque can be selected to avoid excess power and waste of energy.
3. The last step is to match the power. The reducer power must match the motor power. If the power is too small, the reducer will be overloaded and burned out frequently; if the power is too large, resources will be wasted. Conventional slitting machines can be matched 1:1 according to the motor power. It is recommended to reserve about 1.2 times the power margin under heavy load conditions to improve equipment stability.
By mastering these three core parameters and combining your own materials and equipment working conditions, you can accurately match the reducer and eliminate various production problems caused by errors.
