Gearboxes, Hardened & Ground

Nu-Teck Engineering Company has served a wide range of industries with its standard and made to order Mechanical Power Transmission Equipments having various applications such as cranes, extruders, turbines, agitators and aerators, conveyors, wind mills, excavators and stackers, rolling mills, rubber and plastic machinery and in industry like chemical, food, mining, oil, iron and steel, etc. The company offers a range of Hardened & Ground Gearboxes. Salient features: the 'Nu-Ratio' gear reducers are designed as per DIN standards. A starting torque equal to two times running torque is considered while designing 'Nu-Ratio' gear reducers. The gear cases are manufactured in two pieces form graded CI castings with rugged design, free from any blowholes. They are corrosion resistant and can absorb shock and vibration. The housing can also be manufactured from MS fabricated plates, and stress relieved. Inspection covers are provided for viewing gear contacts. Oil level, dispstick and drain plug are fitted at proper places. The helical/spiral gears are manufactured from high quality alloy steel, hobbed with protuberance type cutter. The gears are case carburised, hardened and tempered and precisely ground to give high efficiency and quiet running. Shafts are from alloy steel forgings or bars heat treated to suitable BHN value. The bearings are antifriction; Taper roller or/and spherical roller type fitted on the ground journal. Low speed shaft can be solid or hollow. The bearing life is 15000 working hours (min). Suitable spring loaded single lip type seals are used to prevent the leakage of oil and entry of atmospheric dust. Where the natural cooling from the exposed surface of the gearbox is not sufficient, the gear units are provided with on/two cooling fans mounted on high speed shaft. The gear units are also supplied with external forced feed lubrication system where fan cooling is also not sufficient to keep the temperature of the gear units up to optimum.
