Abstract
The invention discloses an integrated spring piece for an electromagnetic brake. The integrated spring piece is fixed above a friction plate of the electromagnetic brake; each tension spring of the spring piece has an integrated structure; the spring piece comprises a round connecting belt; a plurality of arc-shaped tension springs with the same structure extend out of the periphery of the connecting belt through connecting parts; each tension spring is provided with a fixing hole; each fixing hole is positioned above a concentric circle; and each tension spring passes through each fixing hole through a rivet and is fixed above the friction plate of the electromagnetic brake. The integrated spring piece for the electromagnetic brake is fixed above the friction plate and each tension spring has the integrated structure, so the integrated spring piece has the advantages of simple structure, convenient installation, high concentricity and consistency and capability of ensuring always balanced tensile force.
Description
Technical field
The present invention relates to a kind of electromagnetic braking equipment, particularly relate to a kind of integrated spring piece that is used for electromagnetic brake.
Background technique
At present, permanent-magnet type electricity loss brake has been widely used on the brake assemblies of various power, 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, the spring sheet that traditional permanent-magnet type electricity loss brake is fixed on the friction plate assembly is made up of the identical circular arc extension spring of the structure of three monomers, each extension spring all is fixed on the friction plate by rivet, and the fixed point of three extension springs is on concentric circle, obvious this spring sheet exists installation loaded down with trivial details, the shortcoming of concentricity difference and conformity difference.
Summary of the invention
The object of the present invention is to provide a kind of integrated spring piece that is used for electromagnetic brake, it has simple in structure, and is easy for installation, the characteristics of good concentricity and high conformity.
The objective of the invention is to be achieved through the following technical solutions:
A kind of integrated spring piece that is used for electromagnetic brake, it is fixed on the friction plate of electromagnetic brake, wherein, each extension spring of described spring sheet is an integral structure, comprise connecting band, be extended with most extension springs by joint on the described connecting band, offer fixed hole in the described extension spring.
Described connecting band is a round structure, and its periphery is extended with the identical arc extension spring of most structures by joint, and the fixed hole in the described arc extension spring is on the concentric circle.
Described each extension spring is fixed on the friction plate of electromagnetic brake by rivet.
Beneficial effect of the present invention is that described each extension spring that is used for the integrated spring piece of electromagnetic brake adopts integral structure to be fixed on the friction plate, and is not only simple in structure, easy for installation, and can guarantee that pulling force is balanced all the time, good concentricity, high conformity.
