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.

• 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
• Coupling with hydraulic injection system
• Dimensional accuracy
• Optimum performance
• Shaft ends with u6 tolerance
• Offered with scrapers and forced lubrication, available as per the suitability
• Positive flow of oil into the bearing on either direction of rotation

• Automotive industry
• Steel industry
• Rolling mill industry
• Precisely design

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.

• 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 worlds 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

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

• 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.

We "Nav bharat Engineering Works" is engaged in manufacturing, supplying, trading and exporting high quality range of Industrial Gear Boxes & Gear Coupling , etc. Our products are in high demand across industries such as Stone Crushing Plants, Quarry Plants, Conveyor Equipments, Asphalt Plant, and Road Construction Plants.
