L'importance des boîtes de vitesses agricoles

Boîte de vitesses agricole pour les agriculteurs pour optimiser les performances de la machine, leur permettre de maximiser la productivité. Ces boîtes de vitesses sont composées de fermés dans la coque de l'arbre et de l'engrenage ; la puissance de transmission d'un arbre d'entrée à un ou plusieurs arbres de sortie se situe entre la direction, la vitesse et/ou les changements de rotation de l'arbre d'entrée et de l'arbre de sortie.


Gear wear can bring significant losses to farmers, and they are the primary users of this equipment. Agricultural applications require a high-quality gearbox. From soil preparation to sowing, harvesting, and preparing various goods, the whole food cycle is vital to the gearbox in agricultural equipment. Because with the growth of the population, the demand for food increases, the subsequent equipment wear increase, farmers will need they depend so much on the high quality of machine parts. Otherwise, costly downtime could seriously hinder production and can’t meet the growing demand.

Agricultural right-angle gearbox

Agricultural right-angle gearbox

Agricultural processing equipment, agricultural manufacturing equipment, and agricultural machine drive systems require reliable high-power performance. Delivering this level of performance in an agricultural right-angle gearbox requires high precision gearing as well as quality materials and construction.


High-quality agricultural right-angle gearbox


Right angle gearboxes from Sunfield feature an efficient and compact design, quiet operation, and reliable, economical speed and power transfer. Our right-angle gearboxes feature spiral bevel gears mounted on input and output shafts positioned at a 90-degree angle, allowing the gearbox to intersect one plane or two parallel planes.

The curved teeth of the premium spiral bevel gear improve high-speed contact and reduce vibration and noise. The fully enclosed design provides maintenance-free operation while ensuring that the internal gears will not be out of alignment, clogged, or contaminated with debris.

Standard and IP65 rated helical gear units are available in 1:1 and 2:1 ratio and in bidirectional (one output shaft) or three output shafts) versions.

  • Standard: Black anodized aluminum housing, non-magnetic stainless steel shaft
  • IP65 rating: Nickel-plated aluminum housing, non-magnetic stainless steel shaft, shaft seals, food-grade grease


Flexibility and enhanced traction make the Agricultural Right Angle Transmission an excellent choice for high-volume agricultural applications as well as tractor applications. All units are precision machined, carefully inspected, and pre-lubricated for long life and maintenance-free.

Agricultural Gearbox Repairs

If you own an agricultural machine, you may need agricultural gearbox repairs. These vital machineries must function under the most demanding conditions. Increasing weight loads and temperatures can make these gearboxes unreliable. That’s what Norfolk Bearings does. We rebuild and repair agricultural gearboxes to keep your machine running smoothly. We offer a wide range of services for all types of gearboxes.


Agricultural equipment manufacturers require high-performance, reliable power transmission systems. Bevel gearboxes provide high load capacity for modern harvesters. These systems require reliable, efficient control and easy operation. Leading agricultural equipment manufacturers choose Sunfield Gearbox Company to keep their machines running efficiently and safely. Here are some tips to help you choose the right agricultural gearbox. You can even customize the shaft configuration to suit your needs.


Bevel gearboxes are available in different configurations and design patterns. They are available in motors from 1 hp to 1000 hp. Depending on the application, the Bevel gearbox can use them in reduced-speed applications. Other gearboxes include spiral bevel gearboxes, worm gearboxes, helical gearboxes, cycloidal, inline, and parallel gearboxes.


Maintenance of agricultural gearboxes is a must for Sunfield cutters. Their design and quality have long been proven and passed the American National Standards Institute standards. Sunfield cutters have proven to work more reliably, and they have extra features like thick and durable laminated steel decks that are easier to use and last longer. They also feature a heavy-duty slip-clutch drivetrain for maximum driveline protection. These routers also feature a slip-clutch system and a positive-fitting stump jumper that protects the output shaft from sudden shocks.

Sunfield gearboxes are used for agricultural equipment in numerous industries, including bulk material handling, cement manufacturing, pulp and paper, food and beverage, and chemical processing. Sunfield gearboxes are also a popular choice in the food processing industry because they can handle various applications in pulping and grinding. These are areas where Sunfield systems are known for their quality and reliability.


Compared with other types of agricultural machinery, Sunfield gearboxes have many advantages, such as a high degree of flexibility. If your gearbox has been damaged or you need to get it fixed, you can rely on Sunfield Gearbox Company for your agricultural gearbox repair needs. We specialize in right angle, bevel, worm, helical, worm drives, and spindles for various applications. Our skilled and experienced staff will repair or replace damaged gears for your agricultural gearbox needs.


Sunfield Corporation is a leading manufacturer of high-performance agricultural gearboxes, including reverse engineered and custom-designed gearboxes. Agricultural gearboxes help farmers optimize the performance of their machines by transmitting power from the input shaft to the output shaft. They also allow changing speed, direction, and rotation. They can also repair and replace standard components, including bearings and seals, and help you design and build your custom gearbox.


Agricultural equipment is subjected to severe environmental conditions, including dust, moisture, and heat. For example, equipment used for sowing and tilling crops must remain operational in very wet conditions. In addition, agricultural gearboxes must withstand high temperatures, high-speed operation, and increased weight loads. Due to these factors, these components must maintain the highest level of performance and reliability. For this reason, Sunfield is committed to providing high-quality agricultural gearbox repairs.
