Title: Ball race bearings with snap fit (polyamide) cages - so the cages inhibit axial track displacement
IPC: F16C33/38
Filed: 1975-04-18
Abstract: Ball bearing comprising two coaxial simple or split hoops with radiused steps to define one or more annular ball race tracks. The hoop faces have ancillary steps for engaging a pair of moulded track cage walls so that the cage walls can inhibit relative axial displacement of the coaxial bearing hoops. The cage wall mouldings are pref. made of a resilient material, viz polyamide. Use of the cage walls to maintain alignment allows a higher ball density, and hence working load, to be obtd. than equiv. designs based on hoops designed for eccentric engagement. The snap fit walls supercede use of permanent or temporary ancillary clips during assembly and installation.

Title: Packing between end windings of large machines - comprising fibre bundles with internal duct for resin impregnation
IPC: H02K3/50
Filed: 1976-11-12
Abstract: In large electrical machines, particularly turbo-generators, packing made of elastic tubes filled and expanded with resin is employed to make the whole end-winding assembly solid. The use of tubes of this type does not however necessarily give the required blocking in all directions. To overcome this deficiency long bundles of synthetic fibres are used which have a central duct through which an impregnating resin can be pumped. With the fibre lengths fitted in the correct places, a cold cure resin is pumped into the duct. The resin passes through perforations in the duct wall and, by displacing the air, impregnates the fibres. The outside of the bundle may be covered with a perforated plastic sleeve to contain the fibres.
