Abstract: The invention relates to the field of metal electroerosion machining and may be used in the machining of mated surfaces of different machine parts.The process for the electroerosion machining of pieces with complicated contour and oblique surfaces, realized by means of an electrode-wire rewound onto two bearing elements placed on both sides of the workpiece, consists in that onto the rotary table of the machine tool rigidly joined with the fixed rectangular system of coordinates Oxyz there is fixed the piece-electrode, the axis of which coincides with the axis z, at the same time the electrode-wire is rigidly joined with the mobile rectangular system of coordinates Ox1y1z1. The origin of the rectangular system of coordinates Oxyz and Ox1y1z1 coincides with the precession centre, the axis z1 describes a conic surface with the peak in the precession centre, forming the nutation angle with the axis z. The electrode wire, placed into the spiral flute with arched section made onto the surface of the guide roller and placed at an angle with the axis of the guide roller, which passes through the precession centre, at an angle with the plane formed by the axes x1y1, is communicated a supplementary motion about the axes of coordinates x1 and y1, in accordance with the relation:x=(j+(dsr+rf)/tgβ)(1-cos θ)cosψsinψ,y=(j+(dsr+rf)/tgβ)(sin2ψ +cosθcos2ψ),z=(j+(dsr+ rf)/tgβ)(sinθ cosψ),whereβ - the taper angle of the guide roller;dsr - the diameter of the electrode-wire;j - the electrode clearance;rf - the distance from the axis of the guide roller up to the spiral flute;θ - the nutation angle between the axes z and z1;ψ - the precession angle.Per revolution of the crankshaft of the machine tool the electrode-wire makes a precession and an oscillatory motion around the axis of the guide roller and, the piece-electrode rotates at an angle determined by the relationψ =(Z1 - Z2) 2π/Z2,whereZ1 - the number of teeth of the machined gear-wheel;Z2 - the number of precession cycles.The spiral flute area of the guide roller is equal to the electrode-wire area.

Title: Storage battery
Inventor: BAZHENOV M D
IPC: H01M10/34
Filed: 1998-07-15
Granted: 2000-07-20
Abstract: FIELD: electrical engineering. SUBSTANCE: storage battery built around metal-gas cells has hermetically sealed spherical cylindrical case accommodating electrochemical pack of cells. Electrochemical pack is secured on central rod and braced by means of two flanges and nut turned onto rod. Flanges whose sectional area is specially selected are designed to build up equal compression pressure of 250-400 kgf/sq. cm over inner and outer circumferences of pack. Stiff polymeric rings on electrolyte-containing separators with sealing compound on surfaces being sealed are compressed over inner and outer circumferences of plates which prevents escape of oxygen to common gas space and electrolyte squeezing out of electrochemical pack. Stiff polymeric rings whose outer diameter is greater than that of plates are fitted between series-connected cells to prevent electrolyte leakage over electrochemical pack. Discontinuous compression of negative plates over outer diameter enables hydrogen transfer from common gas space to catalyst-containing layer during discharge and vice versa during battery charge. Electrolyte leakage over current leads and metal plates is excluded due to applying compression pressures to negative plates and current leads at same points. Catalyst-containing and gas-diffusion layers of negative plate constitute integral layer which simplifies assembly of electrochemical pack. EFFECT: improved power capacity of battery. 6 cl, 6 dwg
