In today's highly automated production equipment, the chain has become one of the main transmission components of mechanical transmission.

In today's highly automated production equipment, the chain has become one of the main transmission components of mechanical transmission. Today, Xiaobian mainly introduces the knowledge about the type of chain and lubricant.

Chain

Type of chain

There are many types of chains, which can be divided into transmission chains, conveyor chains, decorative chains, tightening chains, and special chains according to their uses; according to the structure of the chains, they can be divided into: roller chains, sleeve chains, plate chains, nylon Roller chain, scraper chain, collar chain, etc.

Selection of chain lubricants

Selection principles of chain lubricants: Lubricant should be selected as much as possible. For special chains and under special circumstances, grease and dry film lubricants can be selected. It should meet the requirements of lubricants during chain operation to the greatest extent, combined with equipment. And production requirements, the most suitable and economical lubricant is selected.

The main factors to consider when selecting a chain lubricant: the type of chain, the application environment of the chain, the working environment of the chain, the working condition of the chain, the way of lubrication of the chain, and other factors.

Lubrication form of chain

The type of chain lubrication will vary depending on the way the chain is used. Most chain transmissions will use drip oil lubrication and oil bath lubrication, but there are also oil injection lubrication and oil line lubrication.

1. Drip oil lubrication is generally used on fast, long-distance conveyor chains. For example, the chain of baking equipment, the chain of textile equipment and so on. The characteristics of this lubrication method are: good lubrication effect, less waste, without any restrictions, but poor lubrication uniformity.

2. Most of the high-speed transmission chains use oil injection lubrication. The characteristics of this lubrication method are: good lubrication effect, good uniformity, certain limitations, but large waste.

3. Oil bath lubrication method is generally used for closed chain transmission, such as oilfield drilling equipment. The characteristics of this lubrication method are: this should be said to be the most ideal lubrication method, but it has many limitations.

4. There are other ways of lubricating, especially those very short chains, almost all of which are applied by hand: this should be said to be one of the least ideal lubrication methods.

Common types of chain lubricants on the market

At present, there are many types of chain lubricants on the market, but the composition of the chain lubricants is not as follows: mineral oil-based chain lubricants without solid lubricants, mineral oil-based chain lubricants with solid lubricants, and no solids Synthetic base chain lubricants for lubricants, synthetic base chain lubricants with solid lubricants, aerosol chain lubricants, and chain greases.
