What are sprockets?

These are wheels on the circumference of which teeth are formed by machining. Currently, the production of wheels is extremely specialized and precise. Suffice it to say that in most cases machine tools are numerically controlled, and different methods are used depending on the profile of the teeth and the material from which they are made.

The sprocket can be an energy supplier, transmitter or recipient. More precisely, the wheel performs two main functions:

  • He is a tensioner.

Tensions the chain in motor drives.

  • It is part of the propulsion system.

It transfers the drive to the mechanical system.

The sprocket is a key part of the transmission system. It can be found in agricultural and construction machines, cranes, vehicles, lifts, gates, production lines, etc. In other words, it opens, lifts, moves or sets in motion. In many cases, it is simply irreplaceable.

What and how are sprockets made of?

The sprockets are made of the material before it is hardened. As already mentioned, their production requires great precision. Otherwise, the teeth will not interact with the chain links or will damage the chain.

In the first phase, the circles are drawn, but it is important to maintain the so-called tight dimensional tolerance. Due to the repeatability of machining and the requirement to obtain low surface roughness, the precise boring operation is performed by a CNC machine, i.e. a computerized numerical control device. Then the semi-finished product is milled.

Sprockets are made of:

  • Carbon steel of various quality classes;
  • alloy steel;
  • Gray cast iron, unalloyed ductile iron and pearl black cast iron;

The use of the wrong material will result in the sprocket not fulfilling its tasks. The teeth will quickly lose their properties, chip, lose edge sharpness, etc.

Hence the conclusion that the low price of the wheel should raise doubts, and will certainly be the cause of downtime. The failure usually occurs very quickly.

An interesting fact may be the fact that plastic wheels are used in small chain transmissions.

We make sprockets:

  • one-, two- and three-row for standard chains,
  • with chain pitch p= 3/8″, 1/2″, 5/8″, 3/4″ or 1″ (chain reference 06B-1; 08B-1; 10B-1; 12B-1; 16B-1 , 06B-2; 08B-2; 10B-2; 12B-2; 16B-2,06B-3; 08B-3; 10B-3; 12B-3; 16B-3),
  • steel wheels can be in the following condition: raw, induction hardened or through hardened,
  • wheels can also be made of: stainless steel, cast iron, brass, bronze, aluminum, plastic, etc. depending on the requirements and needs.
