Summary of the invention
The utility model mainly provided a kind of simple in structure, quick and easy for installation, reliability is high, and the dustproof electromagnetic brake that can under the rugged environment of moist or many dust, normally use, solved and very easily occurred phenomenons such as brake slip, brake disc corrosion when using under the more or wet environment that exists in the prior art at dust, not only shorten the working life of break, also can cause braking failure, when serious even cause the technical problem of serious accident etc.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of dustproof electromagnetic brake, comprise junction surface and be located at break stator on the junction surface, between break stator and junction surface, be provided with armature, between armature and junction surface, be provided with rotor, rotor links to each other with machine shaft is coaxial, extend on corresponding to the break stator faces of junction surface side and be provided with annular case, the outboard end of described annular case is connected on the junction surface and with junction surface and constitutes confined space, and described armature and rotor are located in the confined space.By the annular case that an integral type connects is set on the junction surface side end face of break stator, and the exterior edge face that makes annular case is connected on the junction surface end face, thereby between junction surface and break stator, form a confined space, and armature and rotor is arranged in this confined space, dust in the environment or moist steam can't enter this confined space thus, make the normally operation in the environment of independence and drying of armature and rotor, simple in structure, the reliability height, and prolonged working life of break; In addition can be before installation go out relative position between junction surface, rotor, armature and break stator according to calculation of design parameters, need not to carry out gap adjustment, promptly finish assembly process when making annular case on the break stator be connected to the junction surface end face, quick and easy for installation, improved manufacturing efficiency.
As preferably, between described annular case and junction surface, be provided with first seal ring, described first seal ring is inlaid in first annular groove on the annular case end face.By first seal ring is set on the junction surface between annular case and junction surface, can prevent that dust or the moisture in the environment from entering confined space in the joint since then, improve the sealing of confined space.
As preferably, in the axis hole of the exterior edge face of described break stator, be embedded with dust cover or oil sealing.By in the axis hole of the exterior edge face of break stator, dust cover or oil sealing being set, can prevent that dust or the moisture in the environment from entering confined space from axis hole, further guarantee the sealing of confined space.
Junction surface can be a motor connecting end end face, and as preferably, described junction surface is located on the flange, is provided with second annular groove on the end face of the outside of flange, is embedded with second seal ring in described second annular groove.By the fixing break of flange, be convenient to break and install, on the end face of the outside of flange, second seal ring is set, can improve the sealing of break and motor connecting end, prevent that dust or the moisture in the environment from entering confined space.
As preferably, between described rotor and machine shaft, be provided with axle sleeve, described axle sleeve links to each other with rotor engaged.By between rotor and machine shaft, axle sleeve being set, be convenient to the rotor dismounting.
Therefore, a kind of dustproof electromagnetic brake of the present utility model has following advantage: by extending on the break stator faces of junction surface side an annular case is set, and make annular case be connected to confined space of formation on the junction surface, armature and rotor are placed in this confined space, make the normally operation in the environment of independence and drying of armature and rotor, dust in the environment or moist steam can't enter this confined space thus, simple in structure, the reliability height, and prolonged working life of break; Need not gap adjustment after the break assembling in addition, quick and easy for installation, improved manufacturing efficiency; By first seal ring is set between annular case and junction surface, flange is provided with second seal ring when connecting on the end face of the outside of flange, in the axis hole of the exterior edge face of break stator, dust cover or oil sealing are set, can prevent that dust or moisture in the environment from entering confined space, improve the sealing of confined space.
