According to the actual load condition of the system, define the input and output of the involute spur bevel gear model. After the system load spectrum is formed, run romax for static analysis, and the system static analysis results can be obtained, including shafting deformation and stress diagram, strength of gear, shaft and bearing, service life and safety factor. Through these results, we can get whether the involute spur bevel gear transmission can operate safely and reliably, and the system can operate normally, so as to carry out the following dynamic analysis of the system.
The first gear load condition is defined. When taking the straight driving condition of the vehicle, the input speed is 1500r / min, the torque is 100nm and the duration is 5h, and the static analysis of the model is carried out. The service life of involute spur bevel gear and the safety factor of involute spur bevel gear can be obtained. It can be seen from the table that the service life (contact life and bending life) of involute spur bevel gear is longer than the operation time set under working conditions, and the safety factor (contact and bending) of involute spur bevel gear is greater than 1, Therefore, the involute spur bevel gear system can operate safely and reliably under the set working conditions.
