Design and Development of Synchro Resolver of Specification “Rotary Conveyor 2.5BT 0.1” which is being used in Hatch door position sending unit. Reduction Gear Unit assembly of code-94, of T-90 Tank.

Synchro Resolver is used in Hatch Door Position Sending Unit Reduction Gear Units of Code-94 Assembly of T-90 Tank. It will synchronise the precise movement of Turret Rotation unit with the cabin position of the commander.

MTPF is manufacturing Hatch door position sending unit reduction gear Assembly of T-90 Tank by using imported Synchro Resolve 2.5 BT/0.1/nw.3.010.399. Due to the ongoing Russia - Ukraine conflict, there are extreme delays in the import of Synchro Resolver / Rotary Transformer.

Hence, production of Hatch door position sending Unit reduction gear Assembly is hampering.

Technical Specification is as below:

• Nominal Excitation Voltage: 27V.
• Operating Voltage Range above: 0 to 27V.
• Nominal Frequency of excitation Voltage: 400 Hz.
• Input impedance at no-load: 1600 Ohms.
• Nominal ratio of conversion: 1.00 ± 0.05.
• Transformation sine dependence error % should not exceed ± 0.1.
• Axial Clearance of Rotor at alternate load 0.75-0.80 Kgf, applicable to shaft end 0.002 – 0.012 mm.
• Radial run out of shaft taper end should not exceed 0.012 mm (during rotation in combination with Bearings).
• Torque of tightening screws M1.6 should not exceed 0.012 N.M (0.25 Kgf cm).
• Misalignment of transformer shaft coupling with drive should not exceed 0.01 mm.
• Mass 0.105 Kg. (Synchro Resolver) & with coupling Assembly 0.127 kg.
