Abstract
The invention relates to a drive mechanism for mowing knives moving to and fro on harvesting machines, with a rotor which rotates in a housing and on which a planet wheel has a double mounting, this planet wheel rolling in a fixed inner toothed ring and being connected to a crank, the diameter of the planet wheel corresponding to the radius of the inner toothed ring and the radius of the planet wheel corresponding to the radius of the crank, and the planet-wheel bearing located furthest away in the housing being mounted on the rotor by means of a releasable bearing holder.
Claims19
Drive mechanism for mowing knives moving to and fro on harvesting machines, with a rotor which rotates in a housing and on which a planet wheel has a double mounting, this planet wheel rolling in a fixed inner toothed ring and being connected to a crank, and the diameter of the planet wheel substantially corresponding to the radius of the inner toothed ring and the radius of the planet wheel substantially corresponding to the radius of the crank, wherein a bearing (7) of the planet wheel (5) located furthest in the housing is mounted on the rotor (2) by means of a releasable bearing holder (11, 13 or 16).
Drive mechanism for mowing knives moving to and fro on harvesting machines, with a rotor which rotates in a housing and on which a planet wheel has a double mounting, this planet wheel rolling in a fixed inner toothed ring and being connected to a crank, and the diameter of the planet wheel substantially corresponding to the radius of the inner toothed ring and the radius of the planet wheel substantially corresponding to the radius of the crank,
- wherein a bearing holder (11) is provided for mounting at least one of two bearings (6,7) and peripherally surrounds the rotor (2) and said at least one bearing,
- said bearing holder (11) being fixed to the rotor (2), and
- a substantially circular segment of said at least one bearing being located in a respective recess (15) formed in said rotor (2) and a remaining segmental portion of said at least one bearing being located in the bearing holder (11),
- whereby radial positioning of said at least one bearing and bearing holder (11) at the rotor (2) is effected.
Drive mechanism for mowing knives moving to and fro on harvesting machines, with a rotor which rotates in a housing and on which a planet wheel has a double mounting, said planet wheel rolling in a fixed inner toothed ring and being connected to a crank, and the diameter of the planet wheel substantially corresponding to the radius of the inner toothed ring and the radius of the planet wheel substantially corresponding to the radius of the crank,
- wherein at least one of two bearings (6,7) of a shaft of the planet wheel (15) is fixed upon the rotor (2) by means of a bearing holder (11) pushed in an axial direction onto the rotor shaft (2), with a substantially circular segment of the at least one bearing located in a corresponding recess (15) of the rotor (2) and a remaining substantially circular segment of the at least one bearing being positioned in the bearing holder (11).
