What is sprocket (Sprockets Category)?

Basically, a sprocket(Category) is a groove wheel with teeth that mesh with links to transfer motion between one wheel and another. Wheels are apply to machinery to convey heavy loads.

  1. They come in different designs and sizes and we can use a variety of materials to produce.
  2. They are available in single strand, double strand, and triple strand.
  3. We can  make a single piece or a hub. They are usually flat or curvy.

The most common type of sprocket is the roller chain sprocket. This type is typically apply to transmission equipment. It operates along chains apply by rollers that are interconnecte by pins. Each pin forms a gap which allows the teeth of the sprocket to move. We often manufacture the sprockets from cast iron, mild steel, or stainless steel.

Someone design sprockets for multi-strand chains which drive higher torque. These sprockets’ applications: in power transmission equipment, agriculture equipment, and bicycles. They are also apply to conveyor systems.

These sprockets are usually bolt-on back together to make installation easier. The sprockets’ typically materials: cast iron, graded stainless steel, or mild steel. The chain sprockets are characterized by high tensile strength and high wear resistance.

Some sprockets have a hub that helps to keep the sprockets from being overhung on the equipment. They are also available in a variety of tooth counts and diameters.

The chain sprockets are available in a variety of sizes, including smaller ones for ash-handling applications. They can also be installed by slackening the chain. Custom-made sprockets are also available a Powertrans, one of the experienced China sprocket suppliers and manufacturers.

How to Select Sprocket Material?

  1. The sprocket material shall ensure that the teeth have sufficient strength and wear resistance, so the sprocket tooth surface is generally heat in order to achieve a certain hardness
  2. The following table shows the heat treatment methods and applicable conditions of different materials.
Materials Heat treatment Tooth surface hardness Applicable conditions:
15#, 20# Carburizing, quenching, tempering 50-60 HRC Z ≤ 25 sprocket with impact load
35# normalizing 160-200HBS Z > sprocket
45#, 50#, ZG310-570 quenching, tempering 40-45HRC Sprocket wheel without severe impact, vibration and wear resistance
15Cr, 20Cr Carburizing, quenching, tempering 50-60HRC High power drive sprocket with Z < 25
40Cr, 35SiMn, 35CrMo quenching, tempering 40-50HRC Important sprocket requiring high strength and wear resistance
A3, A5 welding annealing 140HBS Large sprocket with medium-low speed and medium power
≥HT200 Grey cast iron  quenching, tempering 260-280HBS Sprocket with Z > 50
