3 Terms and definitions

The following terms and definitions defined in GB/T 35089 and GB/T 36491 apply to this document. 3.1 Precision gear transmission Use gears as an important component, and a transmission device with index requirements for angular position accuracy (such as backlash, transmission error, etc.). 3.2 Test sample Installed on the test bench, purposely used for testing and measuring transmission devices. 3.3 Loadcurve The curve of torque, speed and time at the output end of the test piece. Note. According to the preset value and actual measured value, it is divided into target loading curve and actual loading curve. 3.4 Failure One or more technical indicators of the transmission device irreversibly exceed the allowable value of the product, or the components that make up the transmission device (not including Vulnerable parts) are physically damaged.
