Abstract
A drive system including a partition wall; a drive device positioned on a first side of the partition wall, wherein the drive device includes at least one first member positioned on said first side of said partition wall. An actuator for actuating the drive device, where the actuator is positioned on a second side of the partition wall so that the partition wall is between the drive device and the actuator, and where the actuator includes at least one second member positioned on the second side of said partition wall. The second member of the actuator is magnetically coupled to the first member of the drive device, where movement of the second member causes movement of the first member, and to a device including a drive system.
Claims17
A drive system for providing a driving force and/or motion, comprising:
- a partition wall (12);
- a drive device (14) positioned on a first side (18) of said partition wall (12), wherein said drive device (14) comprises at least one first member (20) positioned on said first side (18) of said partition wall (12);
- and
- an actuator (16) for actuating said drive device (14), wherein said actuator (16) is positioned on a second side (22) of said partition wall (12) so that the partition wall (12) is between said drive device (14) and said actuator (16), and wherein said actuator (16) comprises at least one second member (24) positioned on said second side (22) of said partition wall (12);
- wherein said second member (24) of said actuator (16) is magnetically coupled to said first member (20) of said drive device (14), so that movement of said second member (24) causes movement of said first member (20);
- and wherein at least one of said first member (20) and second member (24) is a bearing, namely a ball bearing or cylindrical roller bearing.
A device (1), comprising:
- a drive system (2, 2a, 2b, 2c) comprising:
- a partition wall (12);
- a drive device (14) positioned on a first side (18) of said partition wall (12), wherein said drive device (14) comprises at least one first member (20) positioned on said first side (18) of said partition wall (12);
- an actuator (16) for actuating said drive device (14), wherein said actuator (16) is positioned on a second side (22) of said partition wall (12) so that the partition wall (12) is between said drive device (14) and said actuator (16), and wherein said actuator (16) comprises at least one second member (24) positioned on said second side (22) of said partition wall (12);
- wherein said second member (24) of said actuator (16) is magnetically coupled to said first member (20) of said drive device (14), so that movement of said second member (24) causes movement of said first member (20);
- wherein at least one of said first member (20) and second member (24) is a bearing, namely a ball bearing or cylindrical roller bearing;
- and
- a chamber (10), a wall of which is the partition wall (12) of said drive system (2, 2a, 2b, 2c);
- wherein the drive device (14) of said drive system (2, 2a, 2b, 2c) is allocated within said chamber (10);
- wherein said drive device (14) comprises a component (28) or transmission (30) positioned within said chamber (10);
- and
- wherein said component (28) or transmission (30) is drivable by means of the first member (20) of said drive device (14), which first member (20) is connected to said component (28) or at least one member of said transmission (30), and
- wherein said first member (20) is drivable by said second member (24) of said actuator (16) of said drive system (2, 2a, 2b, 2c) by means of said magnetic coupling between said first member (20) and said second member (24) so that said component (28) or member of said transmission (30) is drivable by means of said second member (24) of said actuator (16).
