A motor and gear unit assembly comprising a gear unit, a motor and a structural connector to which the gear unit and motor are secured, said structural connector being of a substantially elongate shape which extends substantially parallel with the rotational axis of a transmission member which interconnects the axially spaced motor and gear unit, said structural connector having at least a part which is substantially planar and which, in use, is orientated to lie in a substantially vertical plane, one of the gear unit end and motor end of the structural connector being a supported end which is secured to or adapted for securing to supporting structure and the other of the gear unit end and motor end of the structural connector being secured or securable relative to said supporting structure substantially solely by the length of said elongate structural connector between the supported end and said other of the gear unit end and motor end, wherein the motor has a primary direction of rotation, and the motor and gear unit are secured to that side of the structural connector which, in use, with the motor rotating in said primary direction, results in the structural connector experiencing a reactive torque which acts in a direction opposite to the torsional load transmitted along the length of the structural connector to the supported end due to the weight of said motor or gear unit acting at a centre of gravity position displaced horizontally from the plane of said structural connector. |
