Abstract
A device comprises an implement configured to be driven and a first motor and a second motor. Each motor includes a rotational output shaft and a transmission assembly connected to the output shaft. The output shafts of the first and second motors are coupled together by the transmission assemblies such that the output shafts turn at the same rate. The first and second motors contribute equally to the driving of the implement.
Claims20
A device comprising:
- an implement configured to be driven;
- and
- a first motor and a second motor, each motor including a rotational output shaft and a transmission assembly connected to the output shaft, the output shafts of the first and second motor being coupled together by the transmission assemblies such that the output shafts turn at the same rate, the first and second motors contributing equally to the driving of the implement.
A concrete saw comprising:
- a generally rectangular frame having a front end, a read end and a longitudinal length;
- a first motor and a second motor supported by the frame, each motor including a rotational output shaft aligned generally transverse to the longitudinal length of the frame and a sprocket assembly connected to the output shaft, the output shafts of the first and second motors being coupled together by the sprocket assemblies such that the output shafts turn at approximately the same rate, the first and second motors contributing equally to the driving of a saw blade
- the saw blade rotatably connected to the frame via a saw blade shaft oriented parallel to the outputs shafts of the first and second motors, the saw blade shaft having at least one sheave pulley;
- and
- a rotatable jack shaft oriented parallel to the outputs shafts of the first and second motors, the jack shaft having a sprocket and at least one sheave pulley, the sprocket being operably connected to one of the sprocket assemblies of the first and second motors, the at least one sheave pulley being operably connected to the at least one sheave pulley of the saw blade shaft.
