SURFACE TEMPERATURE REDUCTION METHODS BRAKE PAIR FRICTION

Abstract

One of the promising industries is oil engineering, the main task of which is the creation of drilling equipment of increased reliability and durability. A band- block brake (LKT) is one of the main units of hoisting and transport machines and equipment widely used in the oil, gas, mining industry, construction and transport. LCT, which has a number of advantages, differs sharply from other types of brakes. We have rich oil and gas deposits in the republic, which are located in deep and hard-to-reach places. During braking, all factors and parameter values, depending on their interconnected action on each other, change to a large extent, which further complicates the friction process. It is also known that, depending on the materials used, the design of the brake and the operating conditions, there is a sharp change in the friction parameters, especially in braking devices operating under heavy loads. Considering the complexity of the nature of the braking process, the deep analysis shows that, along with the interrelated action of various factors, depending on the design, materials of friction pairs and operating conditions of a given brake, the main dominant factor may be the temperature factor that occurs on the friction surface during the braking process.
