Description
Technical field
The present invention relates to a kind of coupling braking load limiter.
Background technique
Existing coupling has only the function of shaft coupling, is to connect that diaxon or axle together turn round in transmitting movement and dynamic process with revolving meber and a kind of device of not throwing off; Existing break is to be used for a kind of device that mechanism or machine slow down or stop, and also as the movement velocity of adjusting or limting mechanism or machine, it is the vitals that guarantees mechanism or machine safety proper functioning sometimes.Come branch to have two big types from aspect of performance: rigid coupling and flexible coupling; Though two types of coupling all can reach the effect of shaft coupling transmission; But under the situation that machine is overloading, can not protect machine, thereby be prone to cause machine breakdown, can not brake at once yet because of stopping of machine because of overload; Thereby be prone to cause the problem of quality and secure context, therefore existing coupling can not directly be suitable for overload protection and the working environment that needs the machine power-off brake to accomplish simultaneously.Equally, existing break also has only braking function, and load limiter also has only single limit for tonnage function, but possesses coupling/brake and the limit for tonnage function has not just had in the coupling braking load limiter of one.
Summary of the invention
The object of the invention: design a kind of existing shaft coupling function; The coupling braking load limiter that braking function and limit for tonnage protective function are arranged again remedies the not enough aspect of existing single coupling, break and load limiter, and their function is concentrated in together; Make more compact structure, cost is lower.
The technical solution adopted for the present invention to solve the technical problems is:
Housing is fixed on the frame of working machine; On housing, upper end cap, go up setting sleeve assembly, spring stress plate, brake spring assembly, spring seat, plane bearing, down setting sleeve assembly, half initiatively coupling, friction disc support assembly, half driven coupling assembly are arranged installation in order along direction of axis line.Wherein, upper end cap is fixed on the housing with hexagon socket head cap screw, and last setting sleeve assembly is made up of with the shaft block ring that is enclosed within the rolling bearing of setting sleeve cylindrical and be stuck on the setting sleeve the last setting sleeve of band internal spline; The brake spring assembly is by serving as to form with reference to evenly distributing and being fixed on the spring seat four guide rods, being enclosed within four brake springs on four guide rods and being enclosed within four guide rods and be pressed in four spring stress plate and four hexagon socket head cap screws that are through on the spring stress plate on the brake spring with spring seat cylindrical center line; Following setting sleeve assembly is made up of with the shaft block ring that is enclosed within down the rolling bearing of setting sleeve cylindrical and be stuck in down on the setting sleeve the following setting sleeve of band internal spline; The friction disc support assembly arrange to be fitted along shaft axis by friction plate, friction disc support and friction plate in order, rely on glued joint with the riveted joint of four copper rivets 31 be linked together, friction disc support is sandwiched in middle.Two rolling bearings that half driven coupling assembly is connected with interference fit by half driven coupling, form with the lower end cap of rolling bearing cylindrical transition fit and the circlip for shaft that is stuck on the half driven coupling.In above-mentioned; Half active coupling is multiple tooth profile of tooth (starting left hand screw face or starting right helicoid, plane, work left hand screw face or the right helicoid of working are wherein arranged) with half driven coupling tooth surface shape; Half active coupling endoporus is a splined hole, can move along active hub splines direction of axis line.
Half driven coupling is the half-coupling that is fixed on the driven shaft; Half active coupling (refers generally to motor shaft) through the spline inner hole sleeve on the active hub splines; Can on the active spline housing, slide along direction of axis line, friction disc support is stuck on the housing, and a certain amount of displacement is arranged vertically; Can not produce angular displacement, two friction plates are with the friction disc support splicing with being clipped in the middle after the copper rivet riveted joint.
Half active coupling and half driven coupling are realized the function of shaft coupling owing to helical tooth flank meshes the transmission that the axial pressure effect that adds four brake springs realizes moment of torsion; During overload; In order to reach the balance with four brake spring pressure, half initiatively coupling have only vertically to half further four brake springs of compression of coupling direction initiatively, up to being embedded on induction magnetite on the spring seat moves near the fixed position of switch at housing; Make the induction of accepting magnetite near switch; Signal to automatical control system near switch, impel main rotating motor outage, reached the function of overload protection working machine; When half active coupling runs out of steam; Energy stored discharged immediately when four brake springs were compressed; Promotion half initiatively coupling is slided to half driven coupling direction on the active spline housing vertically, makes half active coupling and half driven coupling all produce friction with adjacent friction plate, through being stuck in the friction disc support generation frictional force on the housing; Form braking moment, realize the purpose of braking.
The invention has the beneficial effects as follows to possess the function of coupling, have the function of break and load limiter again simultaneously, accomplish to shut down braking and overload protection working machine function immediately.
Below in conjunction with Figure of description the present invention is specified.
