Abstract
A device for transmitting a movement between a first member and a second member, namely from a driving member to a driven member, of the type having a cylindrical journal with a circular base mounted so as to rotate in a recess of the driven member or of the driving member. At least one of the ends of this journal is hollowed out by a groove capable of forming, on either side thereof, two shoes that are symmetrical with respect to an axial and diametral plane of the journal and capable of engaging, by a flattened surface, with the driving member or the driven member, the cross-section of each shoe being delimited by an arc of a circle matching the external surface of the journal, ending in a line segment that is part of the flattened surface.
Claims7
A device for transmitting a movement from a driving member to a driven member, the device comprising a cylindrical journal with a circular base rotatably mounted in a housing of the driven member or of the driving member, wherein at least one of the ends of the journal is hollowed out by a groove capable of forming on either side thereof two symmetrical shoes with respect to an axial and diametral plane of the journal and capable of coming into contact with the driven member or the driving member via a flattened surface, the straight section of each shoe being delimited by an arc conforming to the outer surface of the journal, ending with a straight segment belonging to the flattened surface,
- wherein the driving member comprises a ramp against sides of which the flattened surfaces of the shoes are capable of being applied,
- wherein the sides of the ramp are symmetrical with respect to a plane, and
- wherein the sides of the ramp form with said plane an angle comprised between 5° and 30°.
A device for transmitting a movement from a driving member to a driven member, the device comprising a cylindrical journal with a circular base rotatably mounted in a housing of the driven member or of the driving member, wherein at least one of the ends of the journal is hollowed out by a groove capable of forming on either side thereof two symmetrical shoes with respect to an axial and diametral plane of the journal and capable of coming into contact with the driven member or the driving member via a flattened surface, the straight section of each shoe being delimited by an arc conforming to the outer surface of the journal, ending with a straight segment belonging to the flattened surface,
- wherein the journal is rotatably mounted in the housing of the driven member, and
- wherein the driving member comprises at least one pair of ramps arranged facing each other;
- between each of the pairs of ramps is arranged the journal rotatably mounted in the housing of the driven member, each of the two ends of this journal forming the pair of shoes whose flattened surfaces are respectively applied against sides of the ramps.
