General This catalog refers to worm gears type U... or worm gear motors type KU... Square housings made of die-cast aluminum are used for this new gear series have a contemporary form. The excellent surface quality makes painting unnecessary. The housing and output flanges of the new worm gears are designed for universal mounting. Also new are the ratios of 70:1 and 5:1 for gearbox sizes 40, 50 and 63 Torque range from 15 Nm to approx. 700 Nm covered, which corresponds to an engine power of 0.12 to 7.5 kW at output speeds between 9 rpm and 280 rpm. The housing parts of the foot and flange versions can be adapted to any installation position due to their variable assembly. The standard program with hollow output shafts avoids expensive ones Coupling connections in favor of a compact and price-conscious machine construction. For Suitable stub shafts can be supplied for special operating conditions. The choice of materials corresponds to the high requirements of rough long-term operation. the Strong aluminum housings are processed as series products on the most modern reusable machines with the highest degree of accuracy. The material pairing of the wheel sets results in a excellent wear resistance, a high fatigue strength and smooth running. The worms made of case-hardened steel are finely ground according to DIN 3967. The wheel rims are made of wear-resistant sling bronze. Most careful controls gearing on modern flank testing machines and the ready-to-install gears Noise test benches guarantee error-free Products. The drive shafts of the gears are equipped with internal threads according to DIN 332, sheet 2, executed. The parallel keys and grooves of the input and output shafts have dimensions according to DIN 6885. Worm gears with drive flange fit all standard motors with B 5 or B 14 Mounting flanges according to DIN 42948. The table shows the motor connection dimensions according to the IEC standard.
