摘要
电站汽轮机或者舰船用汽轮机在传动过程中,经常需要减速器结构来进行传动,该类减速器一般均采用渐开线圆柱齿轮。同时,由于汽轮机产品的结构尺寸大,因此齿轮结构也较大,结合渐开线圆柱齿轮的技术要求,需要保证齿轮的接触面积及间隙,在加工中需要进行特殊的工艺流程保证这种技术要求,通常采用机械加工及配对研磨,进行齿廓修形和倒坡,以满足接触面积要求,进而保证震动噪声和传动的要求。
In the transmission process of power station steam turbines or marine steam turbines,the structure of the reducer is often required for transmission. These reducers generally use involute cylindrical gears. At the same time,due to the large size of the steam turbine product,the gear structure is also large. In combination with the technical requirements of the involute cylindrical gear,it is necessary to ensure the contact area and clearance of the gear. In the processing,special process flow is required to ensure this technical requirement. It is usually machined and matched with grinding to perform profile modification and downslope to meet the contact area requirements,thus ensuring vibration noise and transmission requirements.
