Industrial Gear Box

We are engaged in offering quality certified range of Industrial Gear Box that is widely demanded in rolling mills, sugar mills, cold rolling mill plants, steel industry and automotive industry. Our gear boxes are tested on the international parameters under the supervision of experienced professions. These are made from supreme cast iron inoculated for grain refinement. In this, helical and spiral bevel gearing is offered with addendum correction based on latest scientific finding. The gears are made from genuine chrome nickel molybdenum steel, which are integral or alloy steel rings, shrink fitted onto casted iron or casted steel centers. The internal parts are heat treated up to 300BHN for pinions and up to 260BHN for gear proceeding to teeth cutting.

Helical Gear Box

Our company develops supreme quality Helical Gear Box that is widely used in applications involving high shock loads. These gearboxes maintain superior efficiency and can bear supreme high load applications. It is constructed from cast iron for small and medium size units. In this, the stress zones are amply ribbed against distortions under dynamic load. The internals are heat treated up to 300 BHN for pinions and upto 260 BHN for gears prior to teeth cutting. The shaft extension is provided with long holes at ends and grooves under bearing seats for removal of bearing & coupling with hydraulic injections.

Features

  • External heat exchangers are provided at necessary places
  • Made of casted iron and casted steel
  • Stress zones are adequately ribbed against distortion under dynamic load
  • Provided with long holes in shaft extensions at ends

Double Helical Gear Boxes

Double helical gear has both left- right helical teeth, is used to balance the thrust force and provide additional gear shear area. Also known as Herringbone gears, which resemble two helical gears that have been placed in an adjacent manner. Being double helicals, the thrusts are counter-balanced with no thrust loading on the bearings.

Features

  • Teeth grinded on hofler gear grinder, mot is checked post operation, surface finish, geometrical accuracy, contact with the mating part are checked, 70%, backlash is checked whether it is within the limits.
  • Apex is checked in case of shrink, distance between two gears is checked, and material is 18crnimo6.
  • Gear quality –Din1 and Din 2
  • Teeth cutting on hobbling operation maintaining the teeth grounding allowance. Gear machined using tools and inserts from world’s best tool manufacturer like seco and sandvik
  • Sharpening of gear cutters done on German machine klingenberg sharpener Grinding is done on cnc gear grinder using grinding wheels of Winterthur

Applications
  • Heavy machinery
  • External gear pumps
  • Required on higher pressures & larger percentage of filled materials

Technical Specification:
  • These gears are placed in V shape as two mirrored helical gears joined together. The mirrored arrangement revokes net axial thrust as each half of gear thrusts in opposite direction.
  • To operate in rotational directions, these gears are extended in two possible arrangements for oppositely oriented helical gears/gear faces, one stable and the other unstable.

Spur Gear

Spur gears are the most common type of gears, with straight teeth and parallel to the axis of the wheel. Its simplicity in design, economy of manufacture and maintenance, and absence of end thrust are some of the advantages. Also known as slow speed gears, these impose only radial loads on the bearings. With the only shortcoming of noise, it can be utilized at almost any speed.

Features

  • Highly durable & economical
  • Efficient quality
  • Up to 150 mm OD and 3.5 modules in steel

Applications
  • Gearboxes
  • Mining Equipment
  • Gear Pump Unit
  • Tandem arrangement with internal or external teeth

Technical Specification:
  • Spur helps in transmitting rotational torque by applying force on the teeth of other gear. Being unequal in size, when combined it produces transmission where rotational speed and torque of the second gear needs to vary from the first one.
  • To operate in rotational directions, these gears are extended in two possible arrangements for oppositely oriented helical gears/gear faces, one stable and the other unstable.
