Abstract
The invention discloses a permanent magnet safe brake with high friction coefficient. The brake comprises a base, wherein the base is provided with a magnetic steel framework used for installing permanent magnet steel; the permanent magnet steel has a circular structure; an electrified excitation winding is sleeved on the base; the outsides of the permanent magnet steel and the electrified excitation winding are separately provided with a shell and a friction plate corresponding to the shell; a spring piece is arranged on each friction plate; a plurality of auxiliary balk rings with high friction coefficient are embedded on the contact surface of each shell and the corresponding friction plate; the auxiliary balk rings and the friction surface of the shell are on the same plane; and a plurality of auxiliary balk rings are embedded on the contact surface of the shell of the permanent magnet safe brake with high friction coefficient and the friction plates. The invention has simple structure and is easy to realize; the friction coefficient of the brake is increased, the noise generated in the contact braking process is reduced, the service life of the brake is prolonged, and the brake torque is increased so that the brake can operate more reliably.
Description
Technical field
The present invention relates to a kind of break, particularly relate to a kind of permanent-magnet type electricity loss brake of tool high coefficient of friction.
Background technique
At present, permanent-magnet type electricity loss brake has been widely used on the various electric drivers, its working principle is for leaning on the powerful attraction force of permanent-magnet steel when the power-off brake dead electricity, the absorption that friction plate assembly is firm utilizes the frictional force of friction plate to make the friction plate assembly braking of turning round; When coil electricity, coil produces the magnetic field cancellation that magnetic field produces permanent-magnet steel, spring sheet on the friction plate assembly flicks friction wheel, friction plate assembly just can rotate freely, traditional permanent-magnet type electricity loss brake is when friction disc brake, bump than great dynamics will take place with shell in friction plate, exists noise bigger, break short shortcoming in working life.
