“…Many experimental studies have meshed polymer gears with steel pinions [13][14][15], exploiting steel's relatively good thermal conductivity. Recent experimental comparisons between carbon fibre reinforced PEEK and nylon gears [16][17][18] showed that the load capacity under high running temperature of the former is superior to that of other composite gears. However, despite much empirical testing of different polymer composite gears, there is almost no information available to predict the thermo-mechanical contact performance of real tooth profiles.…”

“…Determined requirements are analysed by other authors to find the major material for polymer gears. Kurokawa et al 7,8 selected the poly-ether-ether-ketone (PEEK) composite gears varying the carbon fibre (CF) reinforcement and lubricating conditions to bending fatigue stress and weight loss criteria. Senthilvelan and Gnanamoorthy 9 analysed the PA 6/6 composites, varying the GF and CF reinforcement for spur gears, without lubricating, observing more heating during gears engagement in the last combination.…”

Polyamide worm gear: manufacturing and performance

The focus of this paper is to establish a characterisation method for seven polyamide (PA) grades to determine the major material to manufacture an automotive worm gear. The composite properties were measured according to the worm gear loadings: tensile strength, Young's modulus, abrasion and impact resistance. They were also correlated to the PA moisture absorption and its glass fibre (GF) reinforcement. The data from mechanical tests were applied in the finite element analysis (FEA) using the von Mises stress criterion. Before the rig tests of the PA worm gears, the injection process was evaluated, through the capillary rheometry. A higher difficulty to process PA 6/6 30% GF was found, due to its lower apparent viscosity. In the end, the influence of moisture absorption was as decisive to the gear's material selection as the GF to the pinion. Thus, the PAs with the best performance were: PA 6 with 30% GF (gear) and with PA 60% GF (pinion).

“…In fact, Kurokawa et al [4,5] reported the performance of plastic gears made of carbon fiber reinforced poly(ether ether ketone) (PEEK/CF), where PEEK/CF specimens with tensile strength of 150-225 MPa were used. These values were much higher than 90 MPa of PEEK itself.…”
