Mining Machine Spare Parts Asbestos Free Mine Hoist Disc Brake Shoe
1. Product description of disc brake shoe for mining machine spare parts
The brake is realized by the friction of friction, which is a process of transforming kinetic energy into heat energy. The friction material used for friction is the first guarantee of the safety and reliability of the brake. Brake shoe is the main part of mine hoist brake, if the friction coefficient of brake shoe can not meet the design requirements, there will be equipment and personal accidents.
2. Wsm-3 environmental protection asbestos free brake shoe, is a resin based friction material and other reinforced fibers instead of asbestos, features:
(1) High friction coefficient, good mechanical strength, small thermal decline;
(2) Does not contain steel wool and high hardness friction agent, low hardness, not easy to damage the brake disc;
(3) Asbestos free, green environmental protection;
(4) Low wear, long service cycle.
3. Material and characteristics of disc brake shoe for mining machine spare parts
The original brake shoes used in China are mostly made of asbestos material, which is characterized by high melting point, large friction coefficient, good mechanical strength, and strong adsorption with adhesive. But asbestos brake tiles also have insurmountable disadvantages:
(1) Because of the poor thermal conductivity of asbestos, friction heat is difficult to disappear quickly, resulting in the thickness of the thermal recession layer wear aggravation, and pollution of the environment, especially asbestos fiber dust will make the human body carcinogenic;
(2) In order to improve the friction coefficient and heat dissipation performance, most of the use of high hardness friction agent and steel wool
(3) The strength of asbestos decreases after complete dehydration and decomposition at 650℃-700℃;
(4) Asbestos is prone to friction "heat recession".
