Abstract

922,058. Electromagnetic brakes. AUTRONIC DEVELOPMENTS Ltd. July 2, 1959 [Aug. 5, 1958], No. 26074/58. Class 103 (1). [Also in Group XXIV] In a magnetic or electromagnetic friction clutch, coupling or brake of the type described in Specification 655,126, wherein one or more members such as discs of magnetic material is or are freely mounted between friction faces of driving and driven elements constituted respectively by a permanent or energizable magnet and an armature, at least one and preferably both of the elements is or are formed of low carbon soft iron the friction surface of which is case-hardened by cyanide hardening and quenching or by coating with a metallic carbide, e.g. tungsten carbide. The freely mounted member is made of soft iron with less than 0.08% carbon and with low silicon manganese and phosphor content, and is coated with phosphate by treating with an insoluble metal phosphate, e.g. p.t.f.e., molybdenum disulphide, or other corrosive resistant dry lubricant or a solution of phosphoric acid and ferrous and manganese dihydrogen orthophosphates. The disc may be case hardened prior to coating with phosphate. The engaging surfaces are highly polished and supplied with lubricant by an oil bath or oil mist.
