NOMIKOS, P. ... et al., 2018. Measurement of vibrations affecting the power transmission seals. Presented at the 4th Biennial International Conference on Powertrain Modelling and Control (PMC 2018), Loughborough University, 10-11th September.
Downsizing of transmission boxes and economic pressures in manufacture has gradually led to
changed sealing conditions in passenger cars. Radial shaft seals are widely used in power
transmission systems to prevent oil leakage from the system. Leaking transmission systems can
lead to both environmental pollution and excessive warranty costs. It is essential to develop a
dedicated experimental rig to simulate the transmission system operation under controlled
environment, providing access for various sensors and data acquisition systems. A pre-requisite
for representative rig design is to determine the in situ vehicle conditions which must be
replicated in such a design. The paper reports on the evaluation of these in situ conditions,
particularly the imposed vehicular vibration conditions.
