| Summary: | The herringbone gear is usually used in the high-speed gear transmission device, and its dynamic particularity under high speed conditions has an important influence on the reliable operation of the equipment. Therefore, the model of the herringbone gear transmission is established, the dynamic characteristics of various herringbone gear transmissions are analyzed under the conditions of driving and load excitation, and the dynamic simulation is carried out, and the product is tested. The results show that when the load is constant, the greater the angular speed of the gear is, the greater the contact force on the gear and the higher the collision frequency will be. When the input speed increases from 500 r/min to 1 000 r/min and 1 488 r/min, the difference of velocity fluctuation amplitude respectively is 2.27 rad/s, 4.76 rad/s and 9.37 rad/s, and the maximum contact force is 1.87 times and 2.44 times those under 500 r/min, respectively. The number of angular velocity fluctuation increases respectively to 1.94 times and 2.94 times in the case of 500 r/min. When the load increases, the angular velocity fluctuation of the driven gear decreases and the contact force increases. This study provides reference for the design of this kind of high-speed gear transmission device. |
