Research output: ThesisMaster's Thesis


A consisting concept model is to be developed and constructed from the existing concept designs of a belt conveyor drive. The aim is to convey the bulk material from ground level to a discharge height of 100 vertical meters at a gradient angle of 32°. Six modular drive units are installed to drive the system, which transmit the necessary power via form fit (gearing). The idea behind this drive variant has already been tested for its feasibility in a test model. In the course of this work, this concept assembly will be developed and converted into a product-ready model. Another topic in this work is the execution of several belt tests on the drive belt. The aim is to find important parameters (elongation, breaking force, profile pitch) as well as a computational estimate of whether tooth engagement is possible and which conveying heights can be achieved with the current system. In addition, the drive system is to be tested in operation in order to be able to assess the behaviour on the real system. Two conveyor belts will be used for this project. The material belt, which is designed as a corrugated edge belt with cleats, is responsible for transporting the bulk material. Since no material samples are yet available for this belt, only the drive belt will be tested for its mechanical and physical properties in this work. The tests required for this purpose take place in Vienna at TÜV Austria GmbH. The material tests can be divided into two main tests. The first test, which is similar to a tensile test, is concerned with finding the elongation function of the drive belt. Here, a distinc-tion is made between elastic and permanent elongation. These parameters are to be determined in the tensile tests. Function graphs can then be formed from the measurement data obtained in order to be able to make a statement about the elongation behavior. The tensile test shows that a residual elongation of 0.2% occurs in the belt. Under maximum prestressing of 450 kN, the elastic elongation component is 0.57%. With the aid of these test results, it was possible to ensure that there is faultless meshing between the material and the drive belt. In the second test, the shear strength of the vulcanized tooth profile was determined. The tooth forces acting during operation result in defined shear stresses that must be absorbed by the material. In the test, it was shown that the teeth can withstand the stresses. Failure of the tooth profile only occurred after a 15-fold increase in the operating force.
