Mechanical moving parts to stop or slow down the drag torque to be applied

Mechanical moving parts to stop or slow down the drag torque to be applied is called the braking torque. Braking torque is the design, selection of brake basis, its size is determined by the type of mechanical work requirements and decisions. The brake friction material used (brake parts) directly affects the performance of the braking process, and the main factors affecting the performance of the operating temperature and temperature rise rate. Friction material should have high and stable friction coefficient and good abrasion resistance. Metallic and non-metallic friction material sub categories. The former are commonly used cast iron, steel, bronze and powder metallurgy friction materials, which has leather, rubber, wood and asbestos.
Realized using the electromagnetic brake brake effect, divided into electromagnetic powder brake and eddy current brake, electromagnetic brake friction and other forms of electromagnetic powder brake ①: forming a magnetic field excitation coil is energized, magnetic magnetization in the magnetic field, forming a magnetic particle chains and between fixed and rotor magnet guide polymerization, by combining magnetic powder brake force and frictional force. Magnetic disappear when the excitation current loose in a free state, the braking action lifted. This hydraulic cutting machine small size, light weight, small excitation power, and braking torque and rotational speed of unrelated parts, but parts of the magnetic powder can cause wear and tear. It facilitates automatic control for a variety of bsp thread port andmating stud end systems.
