The motion model of hypoid gear pair is established. The pinion of hypoid gear pair applies a speed of 60R / min and the driven gear applies a torque of 480nm. The simulation time is 2S and the frame rate is set to 20 frames / sec. The motion simulation and dynamic analysis are carried out respectively, and the simulation results of hypoid gear at low speed are obtained.
| Pinion speed (R / min) | Bearing torque of large gear (Nm) | |
| Low speed condition | 60 | 480 |
| High speed condition | 2800 | 210 |
According to the kinematic simulation and dynamic analysis results of the motion model under the condition of low speed (60R / min), it can be seen from the above figures that in the initial stage of hypoid gear transmission (about 0 ~ 0.98s), the speed and torque curve fluctuate, and the transmission of hypoid gear tends to be a straight line after 1s, which indicates that there is impact vibration between the two wheel teeth in the initial stage of hypoid gear transmission, which is due to the main and It is caused by the different rotation speeds of the driven gears. When the speeds of the two gears are synchronized (after 1s), the speed and torque curves tend to be close to a straight line.
Apply a speed of 2800r / min to the driving gear and a torque of 210nm to the driven gear. The initial speed of the driven gear is set to 2500 rpm, the calculation time is 3S and the frame rate is set to 10 frames / sec. Carry out motion simulation and dynamic analysis respectively, and obtain the results of motion simulation and dynamic analysis of hypoid gear at high speed.
It can be seen from the above figures that in the initial stage of hypoid gear transmission (about 0 ~ 1.95s), the speed and torque curves fluctuate, and the transmission of hypoid gear tends to be stable after about 2S, which indicates that there is impact vibration between the two gears in the initial stage of meshing. When the speeds of the two wheels are synchronized, the speed and torque curves tend to be stable.
From the speed curve and torque curve obtained from the motion simulation and dynamic analysis at high speed and low speed, it can be seen that the fluctuation time range of the curve is basically the same, which verifies the correctness of the motion simulation.
