Abstract
A carrier is suspended and moves on two shafts. The carrier includes a plurality of sealed roller bearings which form openings approximately equal to the dimensions of the shaft. One or more of the bearings is mounted on a leaf spring to provide a predetermined contact pressure between the bearings and the shaft. In addition, damping elements may be substituted for one or more of the sealed roller bearings to minimize interference from vibrations.
Claims1
A suspension system comprising:
- a bar;
- a carrier coupled to the bar and having a plurality of sealed bearings positioned on the carrier to contact the bar, at least one of said sealed bearings being coupled to the carrier by a leaf spring, thereby supplying a predetermined contact pressure between the plurality of sealed bearings and the bar;
- a second bar;
- a second plurality of sealed bearings positioned on the carrier to contact the second bar, at least one of the second plurality of sealed bearings being coupled to the carrier through a leaf spring;
- and at least one damping element coupled to the carrier and disposed to contact the second bar.
