Abstract
An apparatus for adjusting a tension of a pulling device in a pulling-device drive includes a body and a lever arm. The pulling-device drive includes first and second shafts and the pulling device loops around the first and second shafts. The body includes a receptacle adapted to interact with the first shaft and a support point adapted to rotatably dispose the body about an axis of rotation. The lever arm extends from the body so that a spacing between the first and second shafts is modifiable by action of a force on the lever arm.
Claims17
An apparatus for adjusting a tension of a pulling device in a pulling-device drive, the pulling-device drive including first and second shafts and the pulling device looping around the first and second shafts, the apparatus comprising:
- a body having a receptacle and a support point, the receptacle adapted to interact with the first shaft and the support point adapted to rotatably dispose the body about an axis of rotation;
- and
- a lever arm extending from the body, a spacing between the first and second shafts being modifiable by action of a force on the lever arm.
A microscope comprising:
- a pulling-device drive having a first shaft and a second shaft;
- a pulling device operably connected to the first shaft and the second shaft;
- a body having a receptacle and a support point, the receptacle adapted to interact with the first shaft and the support point adapted to rotatably dispose the body about an axis of rotation;
- and
- a lever arm extending from the body, a spacing between the first and second shafts being modifiable by action of a force on the lever arm.
The microscope according to claim 12, wherein the drive axle is operably connected to a motor.
A method for adjusting a tension of a pulling device in a pulling-device drive, the pulling-device drive including first and second shafts and the pulling device looping around the first and second shafts, the method comprising:
- providing a body having a receptacle and a support point, the receptacle adapted to interact with the first shaft and the support point adapted to rotatably dispose the body about an axis of rotation;
- providing a lever arm extending from the body;
- and
- applying a torque via the lever arm so as to adjust the tension of the pulling device.
