Abstract
A speed-adjustable belt-disc sander is provided. The speed-adjustable belt-disc sander includes an electric motor, a first pitch adjustable pulley driven by the electric motor, a second pitch adjustable pulley driven by the first pitch adjustable pulley, a v-belt connecting the first pitch adjustable pulley and the second pitch adjustable pulley, a first pulley driven by the second pitch adjustable pulley, a second pulley driven by the first pulley, a belt sander assembly driven by the second pulley, and a speed adjusting device designed to control an effective belt diameter of the second pitch adjustable pulley, thereby controlling the speed of the belt sander assembly.
Claims20
A speed-adjustable belt-disc sander comprising:
- a belt sander assembly including a sanding belt, a first assembly pulley, and a second assembly pulley;
- an electric motor;
- a first pitch adjustable pulley mounted on a motor shaft of the electric motor;
- a second pitch adjustable pulley mounted on a first shaft different from the motor shaft and a second shaft of the first assembly pulley, the second pitch adjustable pulley being driven by the first pitch adjustable pulley via a v-belt connecting the first pitch adjustable pulley and the second pitch adjustable pulley;
- a first pulley coaxial with and fixed to a fixed flange of the second pitch adjustable pulley on the first shaft;
- a second pulley coaxially mounted to the first assembly pulley and connected to the first pulley through a belt;
- and
- a speed adjusting device designed to control an effective belt diameter of the second pitch adjustable pulley, thereby controlling a speed of the belt sander assembly.
A method for manufacturing a speed-adjustable belt-disc sander, the method comprising:
- providing a belt sander assembly including a sanding belt, a first assembly pulley, and a second assembly pulley;
- providing an electric motor;
- providing a first pitch adjustable pulley mounted on a motor shaft of the electric motor;
- providing a second pitch adjustable pulley mounted on a first shaft different from the motor shaft and a second shaft of the first assembly pulley, the second pitch adjustable pulley being driven by the first pitch adjustable pulley via a v-belt connecting the first pitch adjustable pulley and the second pitch adjustable pulley;
- providing a first pulley coaxial with and fixed to a fixed flange of the second pitch adjustable pulley on the first shaft;
- providing a second pulley coaxially mounted to the first assembly pulley and connected to the first pulley through a belt;
- and
- providing a speed adjusting device designed to control an effective belt diameter of the second pitch adjustable pulley, thereby controlling a speed of the belt sander assembly.
