Abstract
A belt sander is disclosed that may include a sanding assembly having a first roller and a second roller, the sanding assembly being configured to receive a sanding belt around the first roller and the second roller to define a sanding surface therebetweeen. The belt sander may include a motor operationally coupled to the sanding assembly and opposite the sanding surface, the motor being configured to rotate at least the first roller and thereby rotate the sanding belt around the first roller and the second roller, as well as a handgrip formed around at least a portion of the motor and substantially encasing the motor.
Claims20
A drive mechanism for a belt sander comprising:
- a motor;
- a drive pulley operationally coupled to the motor and rotated by the motor;
- a driven pulley operationally coupled to a drive roller of the belt sander to rotate the drive roller;
- and
- a pre-tensioned drive belt around the drive pulley and the driven pulley to translate rotation of the drive pulley by the motor into rotation of the drive roller, the pre-tensioned drive belt having sufficient pre-tensioning to allow slippage of the pre-tensioned drive belt in response to a selected torque value of the motor.
A method comprising:
- determining a torque value of a motor of a belt sander associated with potential damage to the motor;
- selecting a drive belt for the belt sander having a pre-tensioning selected to allow slippage of the drive belt at the torque value;
- and
- fitting the drive belt around a drive pulley and a driven pulley of the belt sander, the drive pulley being operationally coupled to the motor and rotated by the motor, and the driven pulley being operationally coupled to a drive roller of the belt sander to rotate the drive roller.
A belt sander comprising:
- a sanding assembly having a front roller and a rear roller, the sanding assembly being configured to receive a sanding belt around the front roller and the rear roller to define a sanding surface therebetweeen;
- a motor operationally coupled to the sanding assembly, the motor being configured to rotate at least one of the rear roller and the front roller and thereby rotate the sanding belt around the rear roller and the front roller;
- and
- a drive mechanism comprising
- a drive pulley operationally coupled to the motor and rotated by the motor;
- a driven pulley operationally coupled to the rear roller to rotate the rear roller;
- and
- a pre-tensioned drive belt around the drive pulley and the driven pulley to translate rotation of the drive pulley by the motor into rotation of the rear roller, the pre-tensioned drive belt having sufficient pre-tensioning to allow slippage of the pre-tensioned drive belt in response to a selected torque value of the motor.
