Overview
The Xiberui brake USB3-I-500 is suitable for safe braking of large lifting equipment. It is mainly installed in the hoisting mechanism and motor parts of coal mine belt conveyors and steel plant smelting equipment. It has the characteristics of compact structure and large braking force. Due to its outstanding advantages such as simple structure, few parts, and easy maintenance, it has been widely used in most industrial machinery.
Product Details
detailed description:
Xiberui Brake USB3-I-500According to the different materials, friction materials can be divided into two categories: asbestos friction materials and non asbestos friction materials. Asbestos friction materials refer to friction materials that use asbestos as a reinforcing material. Depending on the form of asbestos material added, they can be further divided into the following types:
(1) Asbestos fiber friction material, also known as asbestos wool friction material. There are mainly various types of brake pads, clutch pads, train composite brake shoes, elevator brake shoes, asbestos wool rubber brake bands, etc.
(2) Asbestos wire friction materials mainly include wound clutch discs, etc. Used as friction plates on production engineering machinery, etc.
(3) Asbestos cloth friction materials mainly include drilling rig brake shoes, brake belts, clutch face plates, etc. The base material of asbestos fiber friction material (asbestos velvet friction material) is asbestos short fiber, with a fiber grade of five or six, among which grade five asbestos is used the most. This type of friction material has low cost and can meet the general requirements for material use, making it the most widely used friction material. Asbestos thread and cloth friction materials are made by utilizing the spinnability of asbestos to spin short asbestos fibers into threads, fabrics, or woven tapes. After impregnation with adhesive resin or rubber solution, various friction materials are produced, which have high mechanical strength,Xiberui Brake USB3-I-500Suitable for higher job requirements. Asbestos friction materials have the advantages of high melting point, decent friction coefficient, high mechanical strength, and strong adsorption force with adhesives. They have been widely used as brake friction materials for a long time, but they also have some difficulties to overcome.
Disadvantages:
(1) The friction coefficient of asbestos friction materials is not high, generally around 0.45, and some actual tests only show 0.35, and it is prone to thermal degradation of friction performance, leading to unstable friction coefficient;
(2) Asbestos has poor thermal conductivity, making it difficult for frictional heat to quickly dissipate, resulting in a thicker resin thermal degradation layer and increased wear;
(3) Asbestos materials are prone to environmental pollution, especially asbestos with a diameter less than 3um and a length of 1-100m;
(4) Due to the limitations of asbestos material properties, using high hardness fibers to improve friction coefficient and heat dissipation performance can cause cancerous friction agents and steel wool in the human body. This not only sparks and rusts the friction material, but also causes severe wear on the brake disc and generates high-frequency noise during braking.
