Gear Teeth Matching Method of Power Six-branch Herringbone Gear Transmission System
Power shunt transmission system has been widely used in high-power transmission due to its advantages of strong bearing capacity,large transmission ratio,and compact structure.When each branch gear is fitted,the adjacency condition and transmission ratio condition are considered,and the collision between the gears is avoided,and the interference caused by each pair of gear meshing has become one of the key problems to be considered in the design of the system.Based on the six-branches coaxial transmission power configuration in this paper,a judgment condition is proposed which is easier to determine whether four gear mesh produce interference;and combined with modified gear,they established the teeth matching method of six-branch herringbone gear,which not only can quickly calculate the displacement coefficient of gear mesh not to produce interference,but also obtain the multi-group schemes satisfying transmission ratio and interference error requirements.The calculation results show that the gear design parameters obtained by this method meet all the requirements,which provides a practical method and theoretical basis for the design of a six-branch herringbone gear transmission system in a ship power system.
