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.
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.
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.
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 recommended sealing arrangements when sealing is required between a flange and its mating housing;
— identification codes for flanges and shaft ends — these codes can be used separately or in combination.
