Abstract
A low-offset drive motor system for a pool cover including an in-line torque limiter assembly dimensioned and configured to be positioned substantially within the rope reel of the drive motor system.
Claims20
A torque limiter assembly for a motorized pool cover system, the torque limiter assembly comprising:
- a spline shaft having a proximal end and a distal end, the spline shaft configured to be operatively connected to a drive motor of the motorized pool cover system for rotating the spline shaft;
- and
- a torque coupler operatively connected to the spline shaft adjacent the distal end of the spline shaft and dimensioned and configured to be positioned substantially within a hollow interior of a rope reel of the motorized pool cover system, the torque coupler including a disc assembly having at least one input disc, at least one output disc, and at least one friction disc disposed between the at least one input disc and the at least one output disc, wherein:
- the at least one input disc is operatively connected to the spline shaft such that rotation of the spline shaft causes a corresponding rotation of the at least one input disc,
- the at least one output disc is configured to be operatively connected to a shifting shaft such that rotation of the at least one output disc causes a corresponding rotation of the shifting shaft,
- during a standard operation, the at least one input disc transmits torque to the at least one output disc through the at least one friction disc causing a corresponding rotation of the at least one output disc, and
- when a torque threshold is exceeded, the at least one input disc rotates independently of the at least one output disc and the at least one friction disc.

A drive motor system for a pool cover, the drive motor system comprising:
- a drive motor;
- a torque limiter assembly, the torque limiter assembly including:
- a spline shaft having a proximal end and a distal end, the spline shaft operatively connected to the drive motor adjacent the proximal end for rotating the spline shaft, and
- a torque coupler operatively connected to the spline shaft adjacent the distal end of the spline shaft, the torque coupler including a drive mechanism, a driven mechanism, and a torque threshold such that rotation of the spline shaft causes a corresponding rotation of the drive mechanism and, so long as the torque threshold is not exceeded, rotation of the drive mechanism causes a corresponding rotation of the driven mechanism;
- a shifting gear assembly including a shifting shaft having a proximal end operatively connected to the torque coupler such that rotation of the driven mechanism is operable to rotate the shifting shaft;
- and
- a rope reel operatively connected to the shifting gear assembly such that rotation of the shifting shaft is operable to rotate the rope reel,
- wherein the torque coupler is positioned substantially within a hollow interior of the rope reel.
