INDUSTRIAL CHAIN LUBRICANT NEEDS AND DIFFEENT APPLCIATION METHODS
Chain Pin and Drive Lubrication
Mainly, chain drives are used for the transmission of power used in different types of industries to slide, carry, push, pull or move the different materials from one end to another in various machineries. Chain being an integral part of the industry, chain lubrication is much more important.
About Chain Drive?
It is important to understand the basics of Chain Drive before lubrication need?
So, let us first understand what is a chain and the basic functions of a chain.
To begin with, chains are a series of links connected to one another by pin joints.
They are used to perform the three basic functions:
- Transmitting power,
- Conveying materials and
- Timing purpose.
Chain drives consist of a series of chains that are wrapped around the two sprockets. They are used to transfer the power from one component to another.
Applications of Chain Drives?
As mentioned above, chain drives are used for the transmission of power used in different types of industries to slide, carry, push, pull or move the different materials from one end to another.
Advantages & Disadvantages of Chain Drives
Advantages
Chain drives can be used for short as well as long-distance applications.
It can operate effectively at high temperatures.
Easy to install than belts.
They can withstand abrasive conditions.
They are simpler and less costly than gear drives.
Disadvantages
Chain drives are noisy can cause vibrations inside the machine.
Frequent lubrication is required.
Require precise alignment.
Their service life is less as compare to gear drives.
Load-carrying capacity is less as compare to gear drives.
How Chain Drives Fail and Why?
If a chain drive is overburdened in tension and get stretched or pulled very badly, little cracks will develop in the links or in sidebars of the chain drive if it is repeatedly loaded in tension or stress.
Solid particles, debris or foreign materials can cause wear and result in the failure of chain drive. Also, abrasion and corrosion can be the root cause of chain drive failure.
Why Chain Lubrication is essential?
Lubrication of chain drives is crucial to reduce the wear between the pins and bushings of the chain joints.
It also helps to flush out the solid particles, wear debris and foreign materials to smoothen the functioning.
It is also needed to inhibit rust and corrosion and to carry away heat.
Different lubrication methods for lubrication Chain?
To maximize both the operational life and efficiency of the chain drive, it is important to select perfect lubrication methods among below
Manual Chain Lubrication – Chain lubrication is done manually by using a brush, oil cans or aerosol spray. The gap between the inner and outer link plates of chain drives needs to get lubricate manually. It is one of the most cost-effective options for chain lubrication.
Oil Bath Chain Lubrication – Chain drive is installed in an enclosure and then the bottom of the chain drive dips into an oil basin or tank, forcing the chain lubricant into the chain joints. This is the most effective method as the whole chain drive is being lubricated thoroughly.
Drip Chain Lubrication – This is a semi-automatic method in which the drip cup which supplies the lubricating oil by drip-feeding is mounted in a manner such that the oil will drip on the chains. This is the ideal lubrication method for machinery as you can feed the chain oil to a particular part you want to lubricate.
Force-Feed Chain Lubrication – Continuous spray of oil is supplied to the chain drives with the help of oil feeding pipes. It is recommended for the heavily loaded, high-speed, large horsepower chain drives where other lubrication methods are ineffective. It is the most costly method, it is effective for the performance and life of the chain drives.
