gear transmission error meaning in English

齿轮传动误差

It is well known that the gear contact ratio has a close relation with the gears transmission error , contact pattern , load distribution , influences the gears meshing smooth , noise , dynamic strength and stiffness . based on development of the meshing theory , using tca , ltca and experiments , spiral bevel gears with high contact ratio are researched systematically
众所周知，齿轮的重合度与齿轮传动误差、接触印痕与载荷分配密切相关，进而影响到齿轮啮合的平稳性、噪声、动刚度与动强度等。
