Embodiment Construction

[0015] The subject matter provides a clutchless drive system for plumbing tools, such as drain cleaners, particularly rotary drain cleaners. The drive system includes an electric motor, a torsion member extending from the motor, and one or more damper members disposed alongside the torsion member. This drive system is clutchless.

[0016] The subject matter also provides a rotary drain cleaner using such a clutchless drive system.

[0017] High starting torques are often present in rotary or drum drain cleaners with a direct drive between the drum and the electric motor. This high torque builds up when the motor starts without a soft start or variable speed switch. This torque can cause excessive wear on the driveline and housing. The tool may "jump" when on a stationary surface, or turn when the operator is holding the tool in a hand-held application. Therefore, it is common to utilize a clutch between the driveline and the rotor, allowing the clutch to slip to regulate t...

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).

Description

[0001] priority information [0002] This application claims priority to U.S. Provisional Application No. 62 / 310,076, filed March 18, 2016. technical field [0003] This topic concerns motor dampers and drive trains for plumbing tools such as rotary drain cleaners. This topic also covers motor-driven plumbing tools, such as some drain cleaners that utilize motor dampers and drive trains. Background technique [0004] Powered drain cleaning machines typically utilize a clutch between the motor and the mechanism used to advance or retract the drain cleaning cable or "whip". The incorporation of such clutches may be beneficial, but adds complexity and cost to the machine. [0005] Accordingly, it would be desirable to provide a drain cleaning machine that is clutchless but still provides the characteristics and / or benefits of a machine that utilizes a clutch. Contents of the invention [0006] The difficulties and shortcomings associated with previous approaches are addres...
