Drive hub dampening posts
A window shade system may comprise a drive hub having a dampener comprised of dampening material, wherein the drive hub engages with at least one of a shade tube or a brake hub. The dampener may include one or more tabs that engage the brake hub. The dampener may be configured to dampen the torque from a spinning of the shade tube. The dampener may be comprised of urethane. The dampener may be incorporated onto an outside surface of the drive hub. The dampener may be located within the drive hub. The drive hub may be in the form of a cap that fits over the dampener. The drive hub may include rounded corners. The dampener may be configured in the form of one or more cylindrical rods.
1. A window shade system comprising:
a drive hub having a dampener comprised of dampening material,
wherein the drive hub is in the form of a cap that fits over the dampener,
wherein the dampener includes one or more spacers that engage the brake hub, and
wherein the drive hub engages with at least one of a shade tube or a brake hub.
2. The system of claim 1 , wherein at least one of the drive hub, the brake hub, a drive shaft or a bearing shaft are oil impregnated.
3. The system of claim 1 , wherein the dampener is configured to dampen the torque from a spinning of the shade tube.
4. The system of claim 1 , wherein the dampener is comprised of urethane.
5. The system of claim 1 , wherein another dampener is incorporated onto an outside surface of the drive hub.
6. The system of claim 1 , wherein the dampener is located within the drive hub.
7. The system of claim 1 , wherein the drive hub is at least partially hollow.
8. The system of claim 1 , wherein at least one of the drive hub, the brake hub, a drive shaft or a bearing shaft are comprised of a self-lubricating metal.
9. The system of claim 1 , wherein the drive hub includes rounded corners.
10. The system of claim 1 , wherein the dampener is configured in the form of a cylindrical rod.
11. The system of claim 1 , wherein the dampener comprises four rods.
12. The system of claim 1 , wherein the dampener is located around a shaft that is received by the drive hub.
13. The system of claim 1 , wherein a first end of the dampener interfaces with an actuator.
14. The system of claim 1 , wherein a spacer is located next to the dampener.
15. The system of claim 1 , wherein the dampener comprises two dampeners, and wherein a spacer is located between the two dampeners.
16. A window shade system comprising a drive hub having a dampener comprised of dampening material, wherein the dampener is configured in the form of a cylindrical rod, and wherein the drive hub engages with at least one of a shade tube or a brake hub.
17. The system of claim 16 , wherein the drive hub is in the form of a cap that fits over the dampener.
18. A window shade system comprising a drive hub having a dampener comprised of dampening material, wherein the dampener comprises four rods, and wherein the drive hub engages with at least one of a shade tube or a brake hub.
