FULLY AUTOMATIC HELICAL OR SPUR FIXED POWER GEARBOX COMPLETE WITH AUTO-BLOCKING FOR STEPLESS SPEED ADJUSTMENT BETWEEN ZERO AND MAX. SPEEDS

摘要

The subject invention of the patent is a fully automatic gearbox (the transmission) that ensures stepless speed adjustment between zero and max. speeds in all lever systems, defense industry, tanks, armored vehicles, aerial industry, elevators, escalators, conveyor and similar lifting and transportation systems and rope capstans, etc., where braking is required under the load. The subject invention of the patent is a fully automatic gearbox design that is capable of providing the auto -blocking thanks to its inherent feature and driveline system solely consisted of the helical gears and ensure stepless speed adjustment between zero and max. speeds with very high mechanical efficiency for all rope lever systems, rope capstans, and shipyard windlass without any electromagnetic or electromechanic brake.
