Synthetic resin bearing for photovoltaic tracking system
View Patent ↗A synthetic resin bearing for a photovoltaic tracking system includes first and second bearing members coupled with each other for forming a bearing assembly. Each of the first and second bearing members has a pair of side plate members facing each other. A friction member is positioned between outer peripheral portions of the pair of side plates has an arc-shaped section. A reinforcement member connects the pair of side plates and the friction member, and the first and second bearing members have a coupling protrusion and a concave portion for receiving the coupling protrusion.
1. A synthetic resin bearing assembly comprising first and second bearing members connected to one another, wherein each of the first and second bearing members include a pair of side plates facing one another and having outer peripheral portions; a friction member positioned between the outer peripheral portions of the pair of side plates and having an arc shaped section; and a reinforcement member for connecting the pair of side plates and the friction member, the first and second bearing members having a coupling protrusion and a concave portion for receiving the coupling protrusion.
2. The resin bearing assembly of claim 1 wherein the reinforcement member has a partitioning wall connecting the pair of side plates and the friction member.
3. The resin bearing assembly of claim 1 wherein the friction member includes a guide protrusion at ends thereof.
4. The resin bearing assembly of claim 3 wherein the friction member includes a friction surface having multiple grooves.
5. The resin bearing assembly of claim 4 wherein a width of the grooves increases toward the outer peripheral portions of the bearing members.
6. The resin bearing assembly of claim 1 in combination with a journal bearing housing including a first member and a second member, the resin bearing assembly mounted in the journal bearing housing.
7. The resin bearing assembly and journal bearing housing of claim 6 wherein the first member and the second member are connected to one another and surround the resin bearing assembly, wherein each member is positioned between the pair of side plates and adjacent to the friction members.
8. The resin bearing assembly of claim 1 including a void therethrough extending from one side of the bearing assembly to a second side of the bearing assembly opposite the first side.
9. The resin bearing assembly of claim 8 wherein the void in the assembly has a rectangular shape.
10. The resin bearing assembly of claim 8 further comprising a torque tube fixed within the void.
11. The resin bearing assembly of claim 10 wherein the torque tube is connected to at least one solar panel.
