The KPS3-28J17 is a plastic spur gear with a module of 3 and 28 teeth, designed for metric applications. It features a hub with a finished bore of 17mm, making it suitable for various mechanical assemblies. The gear is manufactured from MC901 nylon, which provides a tooth hardness of 115 to 120 HRR. The pressure angle is set at 20 degrees, ensuring compatibility with standard gear systems. Engineers should note that the gear is susceptible to dimensional changes due to variations in temperature and humidity, which may affect its performance. The allowable torque values are calculated based on assumed usage conditions, and it is recommended to pair these plastic gears with steel gears to mitigate heat generation and expansion issues. The product is available on request, with a lead time of five working days for shipping.
