Abstract A new method for in situ deformation and wear measurement of polymer gears has been developed at the LKT validated polyamide-66 (PA66) constant loading torque rotational speed. This contribution contains a more comprehensive validation newly test by examining polybutylenterephtalate (PBT) under varying conditions. The is based on measuring analysing timing differences between index pulse signals rotary encoders input output shaft rig. Since total tooth combination different effects,...
An in situ gear test rig has been developed at the Institute of Polymer Technology (LKT) to characterize deformation plastic gears during operation. It analyses timing differences between following index pulses rotary encoders on input and output shaft. This measurement principle enables continuous elastic tooth permanent deformations wear operating speed by switching a high low torque. Gear tests using steel-polybutylene terephthalate (PBT) set were performed different rotational speeds...
A new steel-plastic gear set testing methodology has been developed at the Institute of Polymer Technology (LKT). The in situ test rig analyses timing differences between index pulses rotary encoders on input and output shaft. This measurement principle enables continuous elastic tooth deflection one hand permanent deformations wear other by switching a high loading torque low measuring torque. However, using this not yet validated. Therefore, tests polybutylene terephthalate (PBT) gears...
The wear behaviour of PBT-steel gear sets under temporarily changed load has been investigated using an in situ test rig developed at the LKT. method is based on analysing timing differences between index pulses rotary encoders input and output shaft rig. loading torque was varied two levels compared to permanently applied equivalent average terms resulting tooth flank wear. Moreover, number changes analyse influence results show that spectrum determines even if same. it could be shown...
Abstract Friction and wear in a tribological system are directly dependent on the surface structure roughness of friction partners involved. In this article, clear interaction between topologies their depth was identified for material pairing polyamide 66 – steel. The typical correlation wear, initially decreasing increasing after minimizing roughness, found all topologies, albeit at different levels. effect topology is negligible low ( S z < 2.0 µm) with adhesive processes determining...
