A friction disc is a component of a machine that works with the brake shoes to create the braking power. It is used to resist pressing forces as the brake shoe moves through an arc against the wheel of the machine being used. When deciding which friction disc to use for an application, machine owners will look at the kind of machine they are working with, the braking power required, and the area of operation.
In the case of heavy industries where machines like excavators, forklifts, dump trucks, and loaders are used, the Komatsu brand is preferred because it has specialised discs for specialised machines. Some functions they have that set them apart are to enable wet and high-energy braking applications, to withstand high levels of abuse and longer periods of use, and to minimise noise and vibration levels. Some examples of Komatsu excavator friction discs are listed below:
Aside from the excavator, other devices have their specific functions. Knowing the exact machine and part numbers is crucial in finding the right Komatsu friction disc for the required machinery. The job the machine does and the area it works in are also pivotal because mining industries may require a different type of friction disc compared to one used in an excavator dumper in an urban setting.
Another way discs can be differentiated is by the material used to manufacture them. Steel discs are called steel-backed discs, while those manufactured with graphitised material, better known as GMA, are called GMAs. The latter produces less metal noise when in use and is therefore preferred in urban settings where people are living near the area of operation. Those mining more rugged terrain may choose to use a GMA disc that has a higher level of noise so that they can have a more efficient disc working to make their jobs easier.
The specifications of Komatsu friction discs will vary depending on the models and applications. Here are some of the general specifications that are usually matched.
Material
It includes asbetos, semi-metallic, biomimetic material, and ceramic. The materials used for Komatsu friction discs will offer different performance, durability, and heat resistance.
Diameter
The diameter of the Komatsu friction disc will correspond with the size of the machine. It usually ranges from 5 inch(127mm)to 16 inch(406mm).
Thickness
The thickness of the Komatsu friction discs plays a crucial role in determining their performance characteristics. Generally, the thickness of the discs can be very thin, such as 1/8 inch(3.2mm), thinner than 1/8 inch, 1/4 inch(6.4mm)or thicker than 1/4 inch. For heavy machinery equipment, the thickness can up to 1 inch(25.4mm).
Configuration
Generally, Komatsu friction discs will include the external discs, internal discs, and configuration of stack-up. External discs are typically located on the outside of the set, while internal discs are situated inside. Some specific models can also feature a hybrid configuration that combines external and internal discs.
Generally, the durable Komatsu friction clutch discs don't need too much maintenance. However, some minor maintenance tips can extend the lifespan of the friction discs and improve performance.
Inspection
Regular inspections will help users promptly find signs of wear, damage, or deterioration, allowing them to make timely repairs and replacements. The quality and functionality of the machine can be maintained, ensuring safety and stability.
Cleaning
Owners should clean the surfaces of the friction discs regularly to remove dust, debris, and oil. This helps maintain the friction characteristics and ensures the even distribution of the clutches, prolonging the service life.
Lubrication
Doing lubrication to some specific parts of the friction discs can reduce the wear and tear caused by friction and extend their service life. Before doing the lubrication, please make sure the parts need lubrication and the suitable lubricants.
Friction discs face varying scenarios in application and use. Some of them include the following:
Several things must be considered when buying Komatsu friction discs for construction machines and equipment. This is the reason buyers should take the time to research suppliers and their products before making any purchasing decision.
It is crucial first to understand what a friction disc does and why it is vital to the overall working condition of machine equipment. An impact machine's outer metal case called the flywheel is connected to the motor spindle. The job of friction discs is to connect the flywheel and spindle so that the machine can work effectively. The number of friction discs in a machine can vary – usually, there are between three to five. Their work is to support the smooth and seamless functioning of the machine's motor. Without the friction discs, the motor's power would not get transmitted to other parts of the equipment to carry out the intended work functions.
Apart from knowing what a friction disc does, buyers need to understand that friction discs for excavators can be different from those required by other machinery. Seek expert advice and ask questions on the website and product catalog of the supplier to get a better understanding of what kind of Komatsu friction discs are needed to repair particular machines.
The installation manual that shows how to install the friction disc should also be included with the product. The manual will include diagrams and images that clearly depict how to install discs and will show what part of the machine they go into. If there's no manual or the manual is not clear, it should be ok to ask the supplier or seller for further guidance and support.
Know what material friction discs are made of, as this will determine how long they last in the machine. Generally, asbestos was used in many friction discs, but this was soon phased out because of the health risks and dangers associated with the material. Today, semi-metallic materials, steel, rubber, carbon, aramid, or nylon are commonly used in the making of friction discs. This should be looked into as it also impacts the machine's overall functioning when the friction disc is put in place.
Finally, before hitting the purchase button, buyers should compare prices and freight charges. The final price, including freight charges and customs duties, should be calculated before placing the order.
Q1: How can people determine when they need to replace the Komatsu brake disc?
A1: Some indicators can help people to know when to replace the brake disc. One is if they notice a deep groove on the disc. Another is if the disc develops a crack. Moreover, people can tell the disc needs a replacement if it gets thinner than usual. Also, people should replace the disc if they hear strange or loud braking noise. Finally, if the machine brakes are not working properly, it is time to replace the friction disc.
Q2: Are Komatsu brake discs difficult to install?
A2: The good thing about Komatsu friction discs is that they come ready for installation. Therefore, with a little mechanical knowledge, skill, and experience, people can install the disc with ease. However, in order to install it properly and safely, they should follow the manufacturer's guidelines.
Q3: What are some tips for maintaining the Komatsu braking disc?
A3: Generally, the better people maintain their discs, the longer they will last. To maintain the disc well, your machine's braking system should be checked regularly. Also, remember to clean the discs frequently to avoid build-up of debris and dust. Most importantly, ensure the disc is installed properly to avoid premature wear and tear.
