Abstract
A transmission for an adjustable-height platform includes at least one drive shaft, at least one output shaft, at least one first gear wheel configured to transmit a rotational movement of the drive shaft to the output shaft, and at least one second gear wheel configured to drive a hollow second output shaft. The at least one first gear wheel is formed from or includes at least portions formed from plastic.
Claims18
A transmission for an adjustable-height platform comprising:
- a drive shaft;
- a first gear wheel, wherein the first gear wheel is configured to transmit a rotational movement of the drive shaft to a first output shaft, and
- a second gear wheel to transmit a rotational movement of the drive shaft to drive a hollow shaft in a rotational motion, the hollow shaft being a second output shaft,
- wherein the first gear wheel is made from a plastic material, coated with the plastic material, or comprises the plastic material, thus minimizing or avoiding vibration and noise during operation of the transmission,
- wherein a hollow portion of the hollow, second output shaft is in radial alignment with a thickness of the second gear wheel, enabling a threaded rod to pass through the hollow portion of the hollow second output shaft,
- wherein the arrangement enables a first end of the threaded rod to be located on a first axial side of the second gear wheel and wherein the arrangement enables a second, opposite end of the threaded rod to be located on a second, opposite axial side of the second gear wheel.

A transmission for an adjustable-height platform comprising:
- a drive shaft having a steel worm gear;
- a first output shaft having a first worm gear wheel comprising plastic and engaged with the steel worm gear;
- and
- a hollow second output shaft having a second worm gear wheel engaged with the steel worm gear,
- wherein a hollow portion of the hollow second output shaft is in radial alignment with a thickness of the second worm gear wheel, enabling a threaded rod to pass through the hollow portion of the hollow second output shaft,
- wherein the hollow portion of the hollow second output shaft and the second worm gear wheel are arranged enabling a first end of the threaded rod to be located on a first axial side of the second worm gear wheel and wherein the arrangement enables a second, opposite end of the threaded rod to be located on a second, opposite axial side of the second worm gear wheel,
- wherein the first worm gear wheel is made from a plastic material, coated with the plastic material, or comprises the plastic material, thus minimizing or avoiding vibration and noise during operation of the transmission.

A transmission for an adjustable-height platform comprising:
- a drive shaft;
- a first output shaft;
- a first gear wheel, wherein each first gear wheel is configured to transmit a rotational movement of the drive shaft to the first output shaft, wherein the rotational movement of the first output shaft drives a first shaft assembly in a first direction respective to the transmission, and
- a second gear wheel configured to transmit a rotational movement to a hollow, second output shaft, the hollow, second output shaft being a second output shaft, wherein the rotational movement of the respective hollow, second output shaft drives a second shaft assembly in a second direction respective to the transmission,
- wherein the first direction and the second direction are opposite one another,
- wherein a hollow portion of the hollow, second output shaft is in radial alignment with a thickness of the second gear wheel, enabling a threaded rod to pass through the hollow portion,
- wherein the arrangement enables a first end of the threaded rod to be located on a first axial side of the second gear wheel and wherein the arrangement enables a second, opposite end of the threaded rod to be located on a second, opposite axial side of the second gear wheel,
- wherein the first gear wheel is made from a plastic material, coated with the plastic material, or comprises the plastic material, thus minimizing or avoiding vibration and noise during operation of the transmission.
