Abstract
A mechanical joint for transferring rotational motion between shafts at an angle and related assemblies. The assemblies can include both fixed and adjustable-angle joint housings for providing high torques in hard to reach areas. Other assemblies include improvements in inboard marine drives that correct the prop angle to generally align with the direction of travel of the boat and outboard marine drives with improved drive trains.
Claims24
An inboard marine drive system for a boat having a hull comprising:
- an inboard motor disposed within the hull;
- a transmission coupled with the inboard motor;
- and
- a drive shaft having a first end coupled with the transmission and a second end coupled with a propeller disposed outside of the hull;
- wherein the drive shaft comprises a first shaft segment and a second shaft segment, the first shaft segment coupled with the second shaft segment by a first joint for transferring rotational motion from the first shaft segment to the second shaft segment, the first joint comprising:
- a housing having a first end with a first concavity and a second end with a second concavity;
- and
- a first drive puck disposed within the first concavity and pivotable with respect to the housing about a first axis and a second drive puck disposed within the second concavity and pivotable with respect to the housing about a second axis, wherein the first and second drive pucks are cylindrical;
- wherein the first shaft segment is coupled with the first drive puck by a first pin and pivotable with respect to the first drive puck about a third axis, and the second shaft segment is coupled with the second drive puck by a second pin and pivotable with respect to the second drive puck about a fourth axis.
