Dynamic reversible multi-cross section universal modular driveline coupler
View Patent ↗Apparatus and method for an improved driveline coupler having a reversible saddle thereon which allows it to be configured to work with different sizes and shapes of shafts. The reversible saddle is configured on one side to work with one size of driveline shaft and configured on the opposite side to work with a different size driveline shaft so that in the field, an operator can modify the driveline coupler from use with a first size of drive shaft to a second size of drive shaft easily and quickly by turning the saddle upside down.
1. A method for assembling a driveline coupler for a sprinkler irrigation system, comprising the steps of:
a) providing a first load arm on a first end of the driveline coupler for connection to a first shaft;
b) providing a second load arm on a second end of the driveline coupler for connection to a second shaft;
c) mounting a reversible saddle on a portion of at least one of either the first or second load arm;
d) providing an upper side and a lower side on the reversible saddle, wherein the upper side is sized for a first size of either the first or second shaft and the lower side is sized for a second size of either the first or second shaft; and
e) turning the reversible saddle upside down so that it can be used with different sizes and shapes of drive shafts.
2. The method of claim 1 , wherein either the first or second shaft is selected from the group consisting of a round shaft, a rectangular shaft, a triangular shaft, and a octagonal shaft.
3. The method of claim 1 , wherein the reversible saddle has a hole therein capable of receiving a retainer bolt.
4. The method of claim 3 , further comprising a step of providing a retainer bolt disposed in the hole.
5. The method of claim 1 , further comprising a step of providing a center pin disposed in at least one of either the first or second load arm.
6. The method of claim 1 , further comprising a step of providing a PUC disposed between the first and second load arms, the PUC being made of material designed to absorb shock between the first and second load arms during startup of the sprinkler irrigation system.
7. The method of claim 6 , further comprising a step of providing a centering protrusion mounted on at least one of the first and second load arms.
8. The method of claim 1 , wherein the driveline coupling is shimless to permit the driveline coupler to be more easily configured to accommodate drive shafts of differing shapes and sizes while maintaining axial alignment of the first and second shafts.
9. The method of claim 1 , wherein the reversible saddle further comprises a pair of projections each having an angular surface thereon to accommodate drive shafts of differing shapes and sizes.
10. The method of claim 1 , wherein the driveline coupler is modular to permit it to accommodate multiple configurations of the first and second load arms.
