Construction machinery
Gears for the drivetrains of excavators, loaders, cranes and other construction machinery.
On construction machinery, gears work under high torque, shock loads and harsh conditions. The right choice of material and heat treatment therefore directly determines the life of the part.
Frequently made parts
- Gearbox and transmission gears
- Slewing ring and travel drive gears
- Helical and bevel gear pairs
- Gear couplings and drive shafts
Material and heat treatment
Construction machinery gears usually use case-hardening steels such as 16MnCr5, 20MnCr5 and 8620 or through-hardening steels such as 4140. Case hardening hardens the tooth surfaces while keeping the core tough.
Gears commonly produced for this sector
-
Spur gears
The most common gear type: teeth parallel to the axis, transmitting motion and power between parallel shafts.
-
Helical gears
Gears with teeth cut at an angle to the axis, running more quietly and carrying higher loads than spur gears.
-
Bevel gears
Cone-shaped gears that transmit motion between intersecting shafts, usually at 90°.
-
Couplings
A connecting element that joins two shafts to transmit torque while tolerating misalignment.
Frequently asked questions
Do you make large-diameter gears?
The diameter and module that can be produced depend on the machine capacity of the workshop doing the job. Give the dimensions in your request and we will state feasibility with the quote.
Can I get a quote with the original part number?
A part number is useful as background, but production needs dimensions. Sharing a technical drawing, sample or photo with measurements along with the part number speeds up the quote.
