Abstract
The invention discloses a permanent magnet safe brake. The permanent magnet safe brake comprises a pedestal, wherein the pedestal is provided with a magnet steel frame for placing permanent magnet steel; the permanent magnet steel has a circular structure; correspondingly, the magnet steel frame is provided with a plurality of circular magnet steel mounting holes and a plurality of positioning holes; a live exciting magnetic coil is also sleeved on the pedestal; outer shells are arranged outside both the permanent magnet steel and the live exciting magnetic coil; friction plates are arranged to match the outer shells and provided with spring leaves; and the permanent magnet steel in the permanent magnet safe brake has the circular structure; and thus the permanent magnet safe brake has the advantages of simple structure, easy machining, convenient installation and capability of reducing the magnetic leakage of the permanent magnet steel to the greatest extent, and bringing the magnetic energy function of the permanent magnet steel into full play, more uniform magnetic conductance distribution, capability of reducing the magnetic resistance, and increasing the acting force of the magnetic field and more reliable work of the brake.
Description
Technical field
The present invention relates to a kind of break, particularly relate to a kind of permanent-magnet type electricity loss brake.
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, permanent-magnet steel on traditional permanent-magnet type electricity loss brake generally adopts square structure, and there is following shortcoming in this structure:
1) inconvenience is installed, processing cost is higher, and the permanent-magnet steel of square structure is difficult for processing, and because of permanent-magnet steel will be installed in the mounting hole on the magnet steel skeleton, wants careful corresponding four jiaos during installation, otherwise will not install;
2) the permanent magnet leakage field is more, and the magnetic conductance skewness, and magnetic resistance is bigger, can not give full play to the magnetic energy effect of magnet steel.
Summary of the invention
The object of the present invention is to provide a kind of permanent-magnet type electricity loss brake, it is simple in structure that it has permanent-magnet steel, is easy to processing, the less and magnetic resistance features of smaller of leakage field.
The objective of the invention is to be achieved through the following technical solutions:
A kind of permanent-magnet type electricity loss brake, it comprises base, described base comprises permanent-magnet steel assembly department and charged excitation magnetic coil assembly department, described permanent-magnet steel assembly department is provided with the magnet steel skeleton that is used to install permanent-magnet steel, described charged excitation magnetic coil assembly department is provided with charged excitation magnetic coil, and described permanent-magnet steel and charged excitation magnetic coil are provided with shell outward, cooperate described shell to be provided with friction plate, described friction plate is provided with spring sheet, wherein, described permanent-magnet steel is a round structure, corresponding to offering circular magnet steel mounting hole on the magnet steel skeleton.
Also offer most positioning holes on the described magnet steel skeleton.
Described charged excitation magnetic coil assembly department is a cylindrical shape, and the one end extends to the periphery out the permanent-magnet steel assembly department.
Described shell is fixed on the base by fixing bolt, and described spring sheet is fixed on the friction plate by rivet.
Beneficial effect of the present invention is, permanent-magnet steel in the described permanent-magnet type electricity loss brake is set to round structure, not only simple in structure, be easy to processing, easy for installation, and reduced the leakage field of permanent-magnet steel to greatest extent, given full play to the magnetic energy effect of permanent-magnet steel, magnetic conductance is distributed more evenly reduced magnetic resistance, increased the active force in magnetic field, break operation work is more reliable.
