Abstract
There is provided a roller brake system comprising an inner annular member i connected to a bad shaft, an outer annular member 2 constituting a housing of the system, at least one wedge-shaped space at a position along a circumferential direction between said inner annular member i and said outer annular member 2, each said wedge-shaped space having a wider side and a narrower side, said narrower side being narrowing in the ends along said circumferential direction, a drive member 3 connectable to a crankshaft of an engine, said drive member coupled to the inner annular member and provided with protrusions that divide the wedge-shaped space into two sub-spaces each inc a roller 4a or 4b, rollers 4a and 4b, and coil spannular members 5 as elastic members to eject rollers from the ends of the the wedge-shaped space.
Claims (6)
1. A roller brake system comprising: • an inner annular member 1 connected to a load shaft; • an outer annular member 2 constituting a housing of the system; • at least two wedge-shaped spaces at equally distributed along a circumferential direction between said inner annular member 1 and said outer annular member 2, each said wedge-shaped spaces having a wider side and a narrower side, said narrower side being narrowing in the ends along said circumferential direction; • a drive member 3 connectable to a crankshaft of an engine, said drive member coupled to the inner annular member and provided with protrusions that divide the wedge-shaped space into two sub-spaces each including a roller 4a or 4b; • rollers 4a and 4b; and • coil spannular members 5 as elastic members to eject rollers from the ends of the the wedge-shaped space wherein the outer annular member 2 as well as adjacent end cabs and/or bearings establish a closed lubricatable environment.
2. A roller brake system according to claim 1, wherein the inner annular member and the outer annular member have a structure in which a wedge angle of each wedge-shaped space is set at 2° to 12°.
3. A roller brake system according to claim 1 or 2, wherein the inner and outer annular members are made from steel.
4. A roller brake system according to any one of the claims 1 to 3 comprising two wedge-shaped spaces with two sets of rollers.
5. A roller brake system according to any one of the preceding claims, wherein the inner annular member 1 constitutes an end of a load shaft.
6. A roller brake system according to any one of the preceding claims, wherein the drive member 3 constitutes an end of a crankshaft of an engine.
