Durability and design parameters of a Steel/PEEK gear pair
(2019) In Mechanism and Machine Theory 140. p.825-846- Abstract
- The parameters necessary for the reliable design of PEEK gears were determined. The effect of a steel gear's surface on the polymer gear's wear was investigated. Values for the wear coefficient of a steel/PEEK gear pair in dry and lubricated conditions are proposed. Testing showed that, on average, grease lubrication extends the lifespan of PEEK gears by a factor of 1.23, while the additional treatment of steel gears with trovalisation and lubrication extends the lifespan by a factor of 2.54. Temperature measurements were used to determine the coefficient of friction that is required to compute the operating temperature of a steel/PEEK gear pair. Using numerical simulations it was found that a proper tooth tip relief can improve the... (More)
