Problems solved by technology
Design criteria for structural support mounts can be difficult to determine due to variations in the size and height of the motors and gear sets desired to be interconnected and the space required for the gear sets and motors, such as when accommodating different types of couplings and brakes
In addition, the manufacture, handling and transportation of support bases are difficult, especially for those structural support bases that require large lengths
The current structure is therefore expensive and inconvenient

Embodiment Construction
[0018] FIG. 1 shows a motor 4 and a gear set 5 each having mounting feet secured to a cast iron support base plate 6 . The base plate 7 has machined surface regions 7 , 8 to which the motor and the gear set are fastened, respectively. In order to ensure that the alignment of the axes of rotation of the motor and gear set is not negatively affected, it is necessary to ensure that the machining of the surfaces 7, 8 of the support base is precisely controlled.
[0019] A gear set and motor assembly according to the invention is depicted in FIG. 2 .
[0020] The motor and gear set assembly 10 shown in FIG. 2 includes a motor 11, a gear set 12, a transmission coupling 13 for transmitting torque between the motor and the gear set, and a structure providing between the motor and the gear set interconnected connector board 14 .
[0021] The connector plate 14 comprises two end sections, a motor end 15 and a gear set end 16, each of which is substantially flat in shape, and said sect...

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.
Description
technical field [0001] The present invention relates to motor and gearset assemblies, and in particular to such assemblies wherein a structural connector is provided to form a structural interconnection between the gearset housing and the motor housing. [0002] The invention also relates to the use of a structural connector for providing a structural interconnection between a foot-mounted motor and a right-angle or parallel gear set such that the motor and gear set are positioned for torque transmission between the two, and by means of The structural connector is supported relative to the output shaft of the gear set to which the equipment is attached. The motor may thus be secured to the distal end of the structural connector where the connector is substantially unsupported except for connection to the support structure at the gear set end. Background technique [0003] For the drive transmission, a shaft-mounted gear set type comprising a hollow shaft is conventionally u...
