10、rganization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been estab

11、lished has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardizat

12、ion. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 %

13、 of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this part of ISO 3019 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. International Standard ISO 3019-1 was prepared by Techn

14、ical Committee ISO/TC 131, Fluid power systems, Subcommittee SC 2, Pumps, motors and integral transmissions. This second edition cancels and replaces the first edition (ISO 3019-1:1975), which has been technically revised. ISO 3019 consists of the following parts, under the general title Hydraulic f

16、ems, power is transmitted and controlled through a liquid under pressure within an enclosed circuit. Pumps convert mechanical power into hydraulic fluid power, while motors convert hydraulic fluid power into mechanical power. This part of ISO 3019 provides composite dimension reference and identific

17、ation codes for both pumps and motors, simplified dimensional interchangeability for their flanges and shafts, and preferred sizes and dimensions for new designs.INTERNATIONAL STANDARD ISO 3019-1:2001(E)1 Hydraulic fluid power Dimensions and identification code for mounting flanges and shaft ends of

18、 displacement pumps and motors Part 1: Inch series shown in metric units 1 Scope This part of ISO 3019 specifies sizes and dimensions and establishes an identification code for the two- and four- bolt mounting flanges and the shaft ends of positive-displacement, rotary hydraulic fluid power pumps an

19、d motors. It is applicable to cylindrical keyed shaft ends with an external thread, as well as to those without a thread, to conical keyed shaft ends with an external thread and to 30 involute spline shaft ends. NOTE Involute spline is in accordance with SAE J744 1 . 2 Normative references The follo

Shaft ends according to Figure 3 and Figure 6

25、may be provided with a tapped hole. 4.3 Mating components The dimensions and related tolerances of the mating components shall be compatible with the dimensions and tolerances specified in this part of ISO 3019, thus avoiding undue body strain as well as transverse loads on shafts in excess of those

26、 permitted by the pump or motor manufacturer. 5 Identification code 5.1 Mounting flanges Use the mounting flange identification code given in Table 1 and Table 2. The number preceding the hyphen (-) is an approximation, in millimetres, of the mounting flange pilot diameter. The number following the

27、hyphen is the number of mounting bolt holes in the flange. 5.2 Shaft ends Use the shaft end identification codes shown in Tables 3 to 6. The number preceding the hyphen is an approximation, in millimetres, of the shaft major diameter. The number following the hyphen is arbitrarily assigned as follow

28、s: cylindrical keyed shaft ends without thread, -1; cylindrical keyed shaft ends with external thread, -2; conical keyed shaft ends with external thread, -3; 30 involute spline shaft ends, -4. 6 Flange/shaft end combinations Use the preferred flange or shaft end combinations given in Table 7. Use ot

29、her combinations only when necessary, by agreement between the purchaser and the supplier. 1002:19103OSISBBSISO30191:2001 ISO 3019-1:2001(E)3 7 Flange/shaft end concentricity and perpendicularity Maintain flange or shaft end concentricity within 0,25 mm and perpendicularity within 0,002/1, in accord
