28、ociated EFTA Regulations. The extent to which hazards are covered is indicated in the scope of this standard. 1 Scope This European Standard sets out the requirements and/or measures to remove the hazards and limit the risk on work holding chucks which are defined in 3.1. This European standard cove
29、rs all the hazards relevant to this component. These hazards are listed in clause 4. The requirements of this standard concern designers, manufacturers, suppliers and importers of work holding chucks. This standard also includes information which the manufacturer shall provide to the user. This stan
30、dard is primarily directed to components which are manufactured after the date of issue of this standard. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications.

37、ted chuck chuck in which workpieces are clamped with the aid of manual energy (e.g. by means of a key) 3.3 power-operated chuck chuck in which workpieces are clamped with the aid of pneumatic, hydraulic or electric energy 3.4 centrifugally compensated chuck chuck in which there is a system which per
38、mits compensation of the loss of clamping force due to centrifugal force 3.5 base jaw radial moving part of the chuck which receives the top jaw 3.6 top jaw element mounted on a base jaw for the clamping of workpieces 3.7 clamping force algebric sum of the individual radial forces applied by the chu

NOTE The centrifugal force (Fc) is expressed in Newtons (N) 22230=nmrrvmrmFc where: m is the mass in kilograms of the moving parts (usually jaws); r is the distance in metres of the centre of gravity of the moving parts (usually jaws) from the axis of rotation; is t

46、e means listed below shall be used during the design and construction of chucks in order to protect any person from being exposed to hazards: a) The chuck and its proper actuating equipment (e.g. cylinder) shall be compatible (see 6.1.9); b) The balance quality factor G shall be provided by the manu
47、facturers accompanying documents (see ISO 1940-1:1986); c) Base jaws of chucks shall be positively prevented (e.g. by locking pins) from being flung out by centrifugal force (see 3.23.6 of !EN ISO 12100-1:2003“); d) Chucks with mass greater than 20 kg shall be equipped with means (e.g. threaded hole
48、s) for their handling (see 6.2). Verification: by checking the relevant drawings, inspection and type test certificate. 5.2 Special requirements For compensated chucks, nmaxshall be stated by the manufacturer. For non compensated chucks, nmaxshall not exceed the speed corresponding to a calculated l
49、oss of 67% of the total measured static clamping force with the manufacturers standard jaws, e.g. hard top jaw of stated mass mounted on the base jaws positioned at the stated radius of gyration. Verification: by checking the relevant technical file. 5.2.1 Power operated chuck Chuck or chucking equipment (cylinders) shall be equipped with devices to ensure that the clamping force is effectively applied (e.g. travel sensors before stroke end).
