Abstract
The invention relates to a weight compensation device for a drive of a lifting door, for the position-dependent compensation of the weight force of a door leaf of the lifting door, with a force transmission unit which can be coupled to the drive in order to carry out an opening movement which raises the door leaf and a closing movement which lowers the door leaf, wherein at least one compression spring is provided which is arranged in such a way that it supports the opening movement. The invention also relates to a lifting door, in particular an industrial lifting door, which has a door leaf, with a drive, such as a motor, and with a weight compensation device according to the invention.
Claims15
A weight compensation device for a drive of a lifting door for position-dependent compensation of a weight force of a door leaf of the lifting door comprising a drive shaft, which is configured to be coupled to the drive in order to carry out an opening movement which raises the door leaf and a closing movement which lowers the door leaf, wherein the drive is a straight bevel gear drive with a sprocket belt, wherein at least one compression spring is provided and arranged such that the compression spring supports the opening movement, and the compression spring is arranged in a stationary hollow-cylindrical guide element, characterized in that the stationary hollow-cylindrical guide element is non-rotatably attached to a mount for supporting a rotary motion of the drive shaft, and wherein the compression spring is supported at a base part and at an adjusting element, in a force transmitting manner, wherein the base part is fixed with respect to the hollow-cylindrical guide element and the adjusting element is translationally movable relative to the hollow-cylindrical guide element.
