Housing
It is targeted to provide gear boxes with good quality cast iron, and that too with Torsion resistant housing in order to reduce the vibration and its effect and absorb the heat produced by the Engine. Providing the flexibility of producing as per the client's requirements in all kinds of capacity required and give the option of housing of iron to client is also among the aims of the firms.
Gears and pinions
The material used to produce pinion and Gear wheel is made of hard wearing special steel of graded quality in order to allow the individual load conditions. The selection of the raw material like module, foot profile are done in accordance with speeds, ration, and load requirements to give maximum tooth contact and overlap, thus ensuring most preferable meshing and running without any sound.
Shafts
Shafts pinions cut integral used in the manufacture of gear boxes consists of heat treated alloy steel bars or alloy steel forging. Except these, all other shafts are of heat-treated carbon steel and are finished to facilitate high precision tolerance by grinding.
Bearings
The huge success rate of gear boxes is because of the use of quality material and Anti-friction bearings of ample size to ensure that gear boxes have long service life. Antifriction bearings are used to provide high efficiency, best centre distance and accurate shaft alignment. Shaft extensions are fitted with best quality seals to stop oil leakage and dust entry.
Lubrication
In order to achieve the Normal speeds, splash lubrication by dipping gears in oil is provided. The oil level indicator located in the housing is to make sure a required amount of lubricant in the housing.
Cooling
In order to make sure that the heat generated within the gear units is spread and absorbed by a sufficiently large surfaced area of the housing for higher capacities, additional cooling by fans, cooling inside lower housing is used depending on heat dissipation requirement based on power to be transmitted and ambient temperature. Several options are provided to clients regarding some of the features like Shaft extension input/output, integral tooth male clutch with the output shaft and Special Seals.
