DESCRIPTION
Technical Description
This training kit provides the necessary material for joining workpieces with threaded joints. In the process, specific influencing factors (e.g. type of bolt locking, bolt length) can be analysed independently of each other. Bolt tightening and breakaway torques are measured using a torque wrench. The workpieces are held securely in a vice during the experiments.
The material, including the torque wrench, is clearly laid out on a plastic tray. The well-structured instructional material outlines all the necessary technical information and provides a step-by-step guide through the exercises.
Learning Objectives / Experiments
- tightening a threaded joint to a preset torque
- measuring the breakaway torque as a function of the bolt length, property class, bolt locking type and tightening torque
- familiarisation with the relevant standard designations and terms, including graphical representation
