Abstract
A gear stage assembly having a gear stage with two meshing gearwheels for mechanically transmitting a torque includes individual magnets arranged in the form of a ring on each of the gearwheels in a manner corresponding to that of the teeth of the gearwheels, for producing magnetic forces in the gear stage, individual magnets of respective ones of the magnets formed in a ring being arranged with alternating polarity in the direction of rotation and forming a stage of magnets in a ring disposed parallel to the gear stage, for producing a preload torque in the gear stage; and a varnishing unit including the gear stage assembly.
Claims10
A gear stage assembly, comprising:
- a gear stage with two meshing gearwheels for mechanically transmitting a torque, said gear stage including individual magnets each having a magnetic axis, said magnets disposed in the form of non-meshing rings separate from and respectively mounted to each of said gearwheels in a manner corresponding to that of the teeth of said gearwheels, for producing magnetic forces in said gear stage, individual magnets of respective ones of said magnets formed in said rings being disposed with said magnetic axis aligned substantially parallel to a direction of rotation of said gearwheels and with alternating polarity in the direction of rotation and forming a stage of magnets in said rings disposed parallel to said gear stage, for producing a preload torque in said gear stage.
A varnishing unit with a gear stage assembly, comprising:
- a gear stage with two meshing gearwheels for mechanically transmitting a torque, said gear stage including individual magnets each having a magnetic axis, said magnets disposed in the form of non-meshing rings separate from and respectively mounted to each of said gearwheels in a manner corresponding to that of the teeth of said gearwheels, for producing magnetic forces in said gear stage, individual magnets of respective ones of said magnets formed in said ring being disposed with said magnetic axis aligned substantially parallel to a direction of rotation of said gearwheels and with alternating polarity in the direction of rotation and forming a stage of magnets in said ring disposed parallel to said gear stage, for producing a preload torque in said gear stage.
A gear stage assembly, comprising:
- a gear stage with two meshing gearwheels for mechanically transmitting a torque, said gear stage including individual magnets each having a magnetic axis and being disposed in a ring separate from and mounted to each of said gearwheels in concordance with the teeth of said gearwheels, said rings having a defined air gap between one another, and said magnets generating magnetic forces in said gear stage, individual magnets of respective ones of said magnets formed in said ring being disposed with said magnetic axis aligned substantially parallel to a direction of rotation of said gearwheels and with alternating polarity in the direction of rotation and forming a stage of magnets in said ring disposed parallel to said gear stage, for producing a preload torque in said gear stage.
