A Guide to the Types of CG Gearboxes

The increasing competitiveness in every manufacturing segment doesn’t allow to compromise with efficiency and performance of any machine; because saving at production stages turns into profit. One such very common machine used in manufacturing units is gearbox. The blog will help you decide right to buy the best gearbox for the particular application.

Paper industry, cement industry, steel industry, sugar industry, rubber industry, construction industry, etc. are the major users of gearboxes. Gearboxes play an important role in handling a range of industrial and mending functions. The top gearbox manufacturers like the one Crompton Greave (CG) are expanding the range of Greaves Gearboxes to facilitate the end users with application-ready solution. The thick presence of authorized distributors of premium gear boxes facilitates users to get the right advice for choosing the best solutions for efficient energy transmission. The most used gearbox types are-

  1. Helical Gearbox: These case hardened profile ground steel gearboxes are designed to transmit the torque between parallel / right angle shafts with minimum noise. Authorized distributors of Greaves gear boxes offer helical gearboxes up to 5500 kW with reduction ratio up to 650: 1.
  2. Worm Gearbox: These gearboxes are preferred because of their high load carrying capacity and efficiency. These are made available up to 250 kW with reduction ratio up to 4900. These gearboxes commonly find applications in conveyor, material handling, ball mill, agitators, and cranes.
  3. Inline Helical Gear: These are modular in design. These gearboxes are preferred because of high power transmission-to-weight ratio. These are made available from 0.12 kW to 90 kW. These gearboxes find common applications in sugar, cement, paper, solvent extraction, rubber, steel, power plants, etc.
  4. Bevel Helical Cooling Tower Gearbox: The case hardened lapped steel spiral bevel gearboxes are used to transmit the torque between right angle shafts. Authorized dealers of premium gear boxes supply Bevel Helical cooling tower gearboxes up to 600 kW with reduction ratio up to 20.9: 1. More in common applications are in cooling towers and heat exchangers.
  5. Extruder Gearbox: These gearboxes are used transmit high torque required for pressurizing and plasticizing molding materials. These are capable to absorb the high axial thrust load. These are available up to 1410 kW with reduction ratio up to 25.6: 1. More in common applications are for plastic extrusion and PVC extrusion.
  6. Constant Speed Fluid Coupling: In these efficient gearboxes, hydro kinetic energy created by using oil / water is used for power transmission. These are available up to 1500 kW. These are most used in Conveyors, ID fans, ball mills, crushers, slurry pumps, agitators, cranes, etc.
  7. Planetary Mill Gearbox: These gearboxes are preferred because of optimum strength and high efficiency at minimum wear resistance. These are capable to transmit torque range up to 4072 kNm. These are commonly used in sugar mills, coal pulverizing mills, and cement industries.

The range of gearboxes is expanding fast; when you explore the top brands and their authorized distributors, you will find the best match for the cost efficient torque transmission. Selection of right capacity gearbox for a particular machine is very critical as it directly affects to machine performance and production cost. Pro-tip: Authorized dealers and distributors of top gearbox manufacturers provide consultancy also to help you buy the best suitable gearbox.
