Gear, Rack & Pinion

Mechanical Drive Gears

Owing to the years of industrial experience, we have been able to serve our valued clients with a wide range of Mechanical Drive Gears. These drives are manufactured using medium grade carbon steel that ensures their durability. Our precision machined gears are acknowledged for their robust design , sturdy construction , hassle free long service life, excellent surface finish, customization capability and can be utilized for various applications like Speed Reduction or Increase, Torque Multiplication, Resolution and Accuracy Enhancement for Positioning System. We offer these drives in different grades and dimensions and can be Induction / volume hardened for more rugged application as per the requirement of our valued clients.

Our range comprises :

  • Pinion Shaft, Shaft Sprocket and Splined Shaft
  • Helical and Double Helical Gears (max. OD 600 mm, Module 12)
  • Internal Gears (max ID 325 mm, module 12)
  • Spur Gears (maximum OD 825 mm, Module 16)
  • Bevel & Spiral Bevel Gears (up to 425 mm OD, Module 12)
  • Worm Wheel Gear (up to 10 inch CD, Module 16) & Worm Shaft
  • Gear Racks (up to 4000 mm length, Module 26) & Spur Pinion, Helical Rack

Worm Wheel Gear

We manufacture Worm Wheel and Worm Shaft (Worm Gear) using superior quality Phosphor Bronze & Aluminium Bronze Casting in various design and dimension specification. All the three types of Worm Gears i.e. non throated, Single and Double throated, are acknowledged for their rugged construction and robust performance. These worm gears are the apt choice for a combination of high velocity ratio and right angle drive and they provide a large speed reduction (up to 200 : 1) but with significant sliding in minimum possible space. Available in various sizes (Up to Module 16, Center Distance 10", Worm Wheel O.D. 450 mm, Start 8), these worm gears are designed to provide high angular velocity between the nonintersecting shafts. Helically cut for maximum mating, worm wheels have conclave faces to fit the curvature of the Worm Pinion in order to offer line of contact instead of point contact. Depending on the lubricant type, lead angle, surface quality and installation condition, Worm Gears offer smooth and quiet operation and they are perfect for accurate transmission of torque.
