Abstract
The utility model belongs the technical field of automation, particularly relates to a single-wheel double-coil electromagnetic brake. An end cover is in threaded connection with a shell, an armature is in sliding connection with the shell, central spindles at two ends of the armature extend out respectively from the shell and an end cover orifice, a small-resistance coil and a large-resistance coil are fixedly connected through a bracket and the shell, the small-resistance coil is arranged at an inner end inside the shell, and the large-resistance coil is arranged at an outer end inside the shell. The single-wheel double-coil electromagnetic brake has the advantages of novel structure, reasonable design, lowed cost, added starting force, improved performance, lowered temperature rise, reduced power and saved energy.
Description
Technical field
The utility model belongs to technical field of automation.
Background technique
Electromagnetic brake is the key components of lift machine.Though adopt unicoil convenient for production, unreasonable for singly pushing away electromagnetic brake.The working gas gap δ of electromagnetic force F and electromagnet square is inversely proportional to, and air gap is big, and suction is little.When δ is one regularly, whole adhesive of electromagnet or releasing course be, δ from certain certain value to δ=0, be certain definite value from δ=0 to δ perhaps, the former be adhesive, the latter is release.The magnetic resistance value of working gas gap δ decision in this air gap, because fixed when size unshakable in one's determination, then δ is big, magnetic resistance Rm is big, keep enough flux values, requires to increase field current I.Conversely, iron core is adhesive, δ=0, and this moment, the Rm minimum needed field current I minimum.Because singly push away electromagnetic brake generally is long stroke, 20-30mm.Start, in service, air gap delta changes very greatly when keeping, it is also very big that such power that produces differs.Cause the tripping force deficiency, maintenance energy is excessive.Not only waste energy, and the inconvenience raising singly pushes away the electromagnetic brake performance.
Summary of the invention
The utility model provides a kind of dual coil electromagnetic break that singly pushes away, to solve the problem that tripping force deficiency, maintenance energy are excessive, waste energy.The technological scheme that the utility model is taked is: end cap is threaded with housing, armature and housing are slidingly connected, armature two ends mandrel is stretched out by housing and ending cover hole respectively, little resistance coil is fixedlyed connected with housing by support with big resistance coil, little resistance coil is in the housing inner end, and big resistance coil is at the about end of housing.
The utility model is replaced the unicoil that singly pushes away in the electromagnetic brake by twin coil, two coils are controlled by the starter of prior art, and the effect of starter is with two coils from parallel connection of coils when starting, as Fig. 2 (a), behind the instantaneous starting, the series connection of two coils is kept, as Fig. 2 (b).Because the maintenance process air gap delta levels off to zero, then power is very big, and little electric current just can.
The utility model has the advantages that novel structure, reasonable in design, reduce cost, increase tripping force, improve its performance, reduce temperature rise, reduce power, energy saving.
