For the purpose of developing the gear for mini-gear pump, the experimental equipment which combined the electric gear-load testing machine with the thermostatic oven was designed and manufactured. By using this equipment, the strength of the injection molded plastic (CFRP) gear with an axis was investigated under the various water temperature conditions. As the results of this experiment, it is proved that the load of constant speed can be applied on the gear tooth under the environment of fixed temperature. Furthermore, from the results of static-load test in hot water, it is found that the tooth breakage occurs and that the tooth flank deforms plastically and the cracks occur at the dedendum flank of the CFRP gear with an axis. Therefore, the influence of the water temperature on the failure of the CFRP gear with an axis which received static-load is clarified.
