10、deration 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 established has the right to be represented on that com
11、mittee. 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 standardization. International Standards are drafted in accord
12、ance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard require

ISO 23848 consists of the following parts, under the general title Machine tools Ball splines: Part 1: General characteristics and requirements Part 2: Dynamic and static load ratings and rating life ISO 23848-1:2009(E) ISO 2009 All rights reserved vIntroduction
15、 The ball spline is a power transmission component based on recirculating balls, which is designed to translate axially while transmitting torque by an anti-friction means. The ball spline is selected for its smooth operation, high speed capability, low friction and high-radial and high-torsional lo
16、ad capacity. This part of ISO 23848 specifies and standardizes the following characteristics of ball splines: the shapes and dimensions; the test methods; the inspection; the designation; the marking. ISO 23848-2 specifies and standardizes the following properties of ball splines: the basic static a
17、nd dynamic load ratings; the basic static and dynamic torque ratings; the rating life.
