12A-2 Walking Tractor Chain

The 12A-2 walking tractor chain is a type of chain used in agriculture machinery such as walking tractors. It is a roller chain, which means it consists of a series of interconnected rollers that engage with the sprockets of the machine to transmit power and motion.

Walking tractors are commonly used in small-scale farming and gardening, particularly in developing countries. They are versatile and can be fitted with various attachments such as plows, cultivators, and seeders. The 12A-2 walking tractor chain is an important component in these machines, as it helps to drive the wheels and other equipment.

Walking Tractor Chain Features

A walking tractor chain is an essential component of a walking tractor or two-wheeled tractor. Here are some of its key features:

  • Material: Walking tractor chains are usually made of high-quality steel, which makes them strong and durable.
  • Design: The chains are designed with interlocking links that mesh with the sprockets of the walking tractor. This design ensures efficient power transfer from the engine to the wheels.
  • Size: The size of the chain depends on the size of the walking tractor. It can range from small chains for small walking tractors to large chains for bigger machines.
  • Pitch: The pitch of the chain is the distance between the links, and it determines the speed and power of the walking tractor. The pitch can be adjusted by changing the sprocket size.
  • Tensile strength: The tensile strength of the chain is the amount of force it can withstand before breaking. Walking tractor chains have a high tensile strength to handle the stress of heavy workloads.
  • Lubrication: Walking tractor chains need to be properly lubricated to reduce friction and prevent wear and tear. Lubrication also helps to prolong the life of the chain.

Walking tractor chains are built to be strong, durable, and efficient, allowing the walking tractor to handle heavy workloads with ease.

Sprockets for Walking Tractor Chain

Sprockets are a crucial part of the chain system used in walking tractors, as they are toothed wheels that mesh with the chain and drive the wheels or implements of the tractor. These sprockets are typically made of hardened steel or cast iron and are designed to endure the high stresses and wear associated with tractor use.

When choosing sprockets for a walking tractor chain, it is essential to take into account the chain's pitch, the number of teeth on the sprocket, and the bore size of the sprocket. These specifications must match the corresponding specifications of the chain to ensure proper meshing and efficient power transmission.

It is also crucial to consider the quality of the sprockets when purchasing them, as high-quality sprockets will last longer and require less maintenance than low-quality ones. Using mismatched or worn sprockets can result in excessive wear on the chain and reduced tractor performance. WLY, a prominent manufacturer and supplier of mechanical transmission parts in China, also offers high-quality sprockets for sale in addition to chains.

Overall, selecting the correct sprockets for a walking tractor chain is essential for ensuring efficient and reliable operation of the tractor.
