Abstract
An attachment by which a hydraulic pump is to be driven by an outboard motor has a coupling by which the pump shaft is or can be connected to the support established by the fly wheel of the motor or the fly wheel and the upper end of the crankshaft with the weight of the attached pump transmitted to the support. The attachment also includes torque opposing and pump stabilizing means by which the pump is or may be attached to the motor laterally of the fly wheel. In one embodiment of the invention, misalignment forces are accommodated solely by the torque opposing means and in another embodiment the coupling is flexible.
Claims13
An attachment for securing a drive shaft of a hydraulic pump to an outboard motor having a vertical crankshaft and a fly wheel secured to the upper end thereof by a nut threaded on the crankshaft, said attachment including a coupling attachable to said fly wheel and to said drive shaft then to hold said shaft vertical with the weight of the pump transmitted to the crankshaft, and resiliently yieldable torque opposing means connected to the pump and to said motor laterally of the fly wheel, said torque means laterally yieldable to accommodate misalignment forces.
An outboard motor including a vertical crankshaft, a fly wheel on the upper end thereof, and a nut threaded on said crankshaft end and securing said fly wheel, a hydraulic pump including a drive shaft, a coupling secured to said pump shaft and to said fly wheel with said pump shaft vertical and transferring the weight of the pump to said crankshaft, and resiliently yieldable torque opposing means connected to the pump and to said motor laterally of the fly wheel, said torque means laterally yieldable to accommodate misalignment forces.
