Abstract
Method for measuring the bearing play in a highly dynamic mechanical transmission chain between a setting member and a functional member on which it acts, wherein a control unit actuates the setting member with a square-shaped desired signal of at least half a period and a measuring device is provided with a sensor for sensing the position of the functional element measures its distance from a reference point of the functional element, and the bearing play is determined from the comparison of the actual deflection with the command signal of the setting member.
Claims14
Method for measuring the bearing play in a highly dynamic mechanical transmission chain comprising a setting member which acts on a functional element and the interaction of which generates the bearing play to be measured, comprising a control unit to actuate the setting member and an evaluator to gather the measured values, wherein
- a measuring device is provided with a sensor for sensing the position of the functional element, whereby the sensor measures its distance from a reference point of the functional element,
- the control unit actuates the setting member by means of a square-shaped desired signal of half a period and the bearing play is determined from the comparison of the actual deflection with the command signal of the setting member.
A method for measuring a bearing play in a highly dynamic mechanical transmission chain having a setting member which acts on a functional element, comprising the steps of:
- actuating the setting member, wherein a control unit commands actuation of the setting member in accordance with a predetermined signal to cause a commanded deflection of the functional element;
- measuring a deflection of the functional element during the actuation of the setting member, wherein a measuring device provided with a sensor senses a distance between the sensor and a reference point of the functional element;
- and
- determining the bearing play between the setting member and the functional element from a comparison of the measured deflection with the commanded deflection.
An apparatus for measuring a bearing play in a highly dynamic mechanical transmission chain having a setting member which acts on a functional element, comprising:
- a control unit, wherein the control unit commands actuation of the setting member with a predetermined signal to cause a commanded deflection of the functional element;
- a measuring device provided with a sensor which senses a distance between the sensor and a reference point of the functional element, wherein the measuring device measures a deflection of the functional element during actuation of the setting member;
- and
- an evaluator which determines the bearing play between the setting member and the functional element from a comparison of the measured deflection with the commanded deflection.
