一、前言十字销型万向轴,是许多万向轴中有代表性的一种。由于这种万向轴可以采用大的折角而且传动效率又高,所以作为汽车传动轴获得了广泛的发展。目前,从造纸机械、轧钢机械的轧辊驱动,到净排水场的水泵驱动等,都广泛采用这种万向轴。此种万向轴在净排水场用于立式水泵驱动 I. Introduction Cross-pin universal shaft, is a representative of many universal shaft. As a result of this universal shaft can be used with large angle and transmission efficiency and high, so as a vehicle drive shaft has been widely developed. At present, such universal shafts are widely used from papermaking machines, roll drives for rolling machinery, to pump drives for net drains. This type of cardan shaft is used for vertical water pump drive in a net drain field
