Abstract:
The present invention relates to an arrangement (100) for a sailing boat furling system, and for reception of or comprising an outgoing shaft (11) exposed to external torque loads. It comprises a furling drive unit (20) with a gear mechanism (22) and a motor unit (23) connected to an ingoing, motor, shaft (21) and a ratchet mechanism (10) comprising a locking functionality. The ratchet mechanism comprises a housing (17A,17B) and takes up the outgoing shaft (11). The furling drive unit (20) is connectable to ratchet mechanism (10) and is so arranged that the motor unit (23) will be located distant from the outgoing shaft (11), and it further comprises a control unit (30) arranged to control the motor unit (23) driving the ingoing shaft (21). The outgoing shaft can be switched between an engaged mode, in which the outgoing shaft (11), when exposed to external torque loads in a first direction, is allowed to rotate in an opposite, second, direction but prevented from rotating in a said first direction, hence protecting the motor unit and the gear mechanism (22) from external torque loads on the outgoing shaft (11) which are transferred to or taken up by the ratchet mechanism (10), and a disengaged mode in which the outgoing shaft (11) and the ingoing shaft (21) are allowed to rotate in both directions, by controlling, by means of the control unit (30), the movement of the ingoing shaft (21), and thereby, via the ratchet mechanism (10), the outgoing shaft (11) between being in the engaged mode and in the disengaged mode.
