Abstract
A pier for a solar tracking system includes a bearing housing assembly, a frame, the frame defining an A-profile having a pair of legs and a crown at a center portion thereof, and a mounting bracket, the mounting bracket coupled to a portion of the crown of the frame at a first portion thereof and coupled to a portion of the bearing housing assembly at a second portion thereof.
Claims15
A support for a solar tracking system, the support comprising:
- a bearing housing assembly, the bearing housing assembly configured to rotatably support a torque tube of the solar tracking system;
- a pair of legs coupled to the bearing housing assembly, each leg of the pair of legs extending downwardly and outwardly from the bearing housing assembly;
- and
- a damper assembly configured to provide resistance to rotation of the torque tube rotatably supported by the bearing housing assembly, the damper assembly comprising:
- an upper damper mount, the upper damper mount operably coupled to the bearing housing assembly;
- a pair of lower damper mounts, each of the lower damper mounts coupled to a corresponding leg of the pair of legs, at least one of the lower damper mounts including an upper plate and a lower plate, the upper plate having a lower surface including a tab extending downwardly from the lower surface, the tab including a post extending outwardly from the tab, the tab including a protuberance extending downwardly from a lower portion of the tab, the protuberance configured to be received within a corresponding dimple defined in an upper surface of the lower plate to inhibit movement of the upper plate relative to the lower plate;
- and
- a pair of struts, each of the struts operably coupled to the upper damper mount at a first end portion of each respective strut, and each of the struts operably coupled to a corresponding lower damper mount of the pair of lower damper mounts at a second, opposite end portion of each respective strut, at least one of the struts configured to be operably coupled to the post of the at least one lower damper mount,
- wherein rotation of the upper damper mount effectuates a compression of a first strut of the pair of struts and an extension of a second strut of the pair of struts.

A support for a solar tracking system, the support comprising:
- a bearing housing assembly, the bearing housing assembly configured to rotatably support a torque tube of the solar tracking system therein;
- a pair of legs coupled to the bearing housing assembly, each leg of the pair of legs extending downwardly from the bearing housing assembly;
- and
- a damper assembly configured to provide resistance to rotation of the torque tube rotatably supported by the bearing housing assembly, the damper assembly comprising:
- an upper damper mount, the upper damper mount configured to be operably coupled to a portion of the torque tube of the solar tracking system;
- a pair of lower damper mounts, each of the lower damper mounts coupled to a corresponding leg of the pair of legs, at least one of the lower damper mounts including an upper plate, a lower plate, and a split collet interposed between the upper plate and the lower plate, the upper plate and the lower plate each having a tapered surface thereon, the tapered surfaces of the upper plate and the lower plate configured to abut corresponding tapered surfaces of the split collet;
- and
- a first strut and a second strut, each of the first and second struts operably coupled to the upper damper mount at a first end portion of each of the first and second struts, and each of the first and second struts operably coupled to a corresponding lower damper mount of the pair of lower damper mounts at a second, opposite end portion of each of the first and second struts,
- wherein rotation of the upper damper mount effectuates a compression of one of the first strut and the second strut, and an extension of the other of the first strut and the second strut, and
- wherein drawing the upper plate and the lower plate towards one another causes the tapered surfaces of the upper plate and the lower plate to abut the tapered surfaces of the split collet and effectuate a perpendicular translation of the split collet relative to the upper plate and the lower plate.
