適用范圍：1.1 This part of ISO 3019 specifies dimensions and establishes an identification code for mounting flanges of positive displacement rotary hydraulic fluid power pumps and motors having a geometry which cannot accept a flange covered in ISO 3019-2.1.2 This part of ISO 3019 also specifies dimensions and establishes an identification code for shaft ends of positive displacement rotary hydraulic fluid power pumps and motors of the following types :— cylindrical shaft end with key;— conical shaft end with key and external thread;— cylindrical shaft end with metric involute spline.1.3 This part of ISO 3019 establishes a metric series of mounting flanges and shaft ends for positive displacement rotary hydraulic fluid power pumps and motors.1.4 This part of ISO 3019 provides— a minimum number of flanges and shaft sizes to cover probable present and future requirements;— dimensional interchangeability of flange and shaft end mountings;— flange and spigot dimensions which allow for recom-mended sealing arrangements when sealing is required be-tween a flange and its mating housing;— identification codes for flanges and shaft ends — these codes can be used separately or in combination.
