Abstract
Motor dampening provisions are described. Incorporation and use of the motor dampener(s) in a rotary type drain cleaning machine enables elimination of a clutch in the machine. Also described are clutch-free drive systems using the motor dampener(s). Also described are torque countering members that are used in conjunction with the motor dampener(s).
Claims15
A drain cleaner comprising:
- a drain cleaner housing defining an interior region and at least one cradle member therein;
- a motor having a drive shaft rotatable about a center axis, and a motor enclosure, the motor enclosure received and supported by the at least one cradle member within the interior region of the drain cleaner housing;
- a torque countering member protruding outward from the motor enclosure generally perpendicular to the center axis of the motor and defining a first side and an oppositely directed second side;
- a first dampener member defining a first longitudinal axis oriented perpendicular to the center axis and offset by a first distance from the center axis extending between the first side of the torque countering member and the drain cleaner housing and configured to resist rotation of the motor enclosure about the center axis in a clockwise direction,
- a second dampener member defining a second longitudinal axis oriented perpendicular to the center axis and offset by a second distance from the center axis extending between the second side of the torque countering member and the drain cleaner housing and configured to resist rotation of the motor enclosure about the center axis in a counterclockwise direction,
- a drum connected to the drive shaft, and
- a drain cleaning cable connected to the drum such that it is configured to be advanced into or be retrieved from a drain pipe.
