Abstract
The utility model discloses an electrical block resilient shaft coupling belonging to the hoisting equipment, and adopts the following main structure: a spring is arranged between a kinetic friction pair and a static friction pair; the elasticity of the spring can just burst through the kinetic friction pair. Through the kinetic friction pair and the static friction pair of the resilient shaft coupling with the inside provided with the spring, the utility model can absorb and compensate the axial displacement generated by a hoisting tapered rotor motor braking device, thereby ensuring the normal running of an electrical block.
Description
Technical field
The utility model relates to a kind of crane gear, particularly a kind of electric wire hoist elastic coupling flexible coupling.
Background technique
Electric wire hoist generally is made up of parts such as motor, retarder, reels, and motor drives reel by retarder and rotates, and utilizes the wire rope hoisting heavy that is wrapped on the reel.Electric wire hoist is a kind of frequent crane gear that uses, the security requirement height, so the electric wire hoist planted agent is provided with braking device.Existing electric wire hoist utilizes the conical rotor motor of band brake to reach the braking purpose.During this motor outage, under the effect of spring, rotor moves to big end, drags the brake sticking brake of rotor small end; During energising, electromagnetic force overcomes the active force of spring, and rotor is moved to small end, and band-type brake unclamps, and rotor enters working state.Hence one can see that, and during the motor outage, can spring force rotor in time to move to big end, is the key that drags the braking of rotor small end band-type brake device.
Retarder, reel and machine analysis, motor output shaft, elastic coupling flexible coupling, jack shaft, spline housing and reducer input shaft become axis to contact mutually.Motor after the speed reducer deceleration, is delivered to roll device with transmission of power through elastic coupling flexible coupling, jack shaft, spline housing, drives suspension hook and carries out hoisting operation.The relative position of retarder, reel and motor is fixed, and the axial displacement that the conical rotor motor rotor motion produces can only be absorbed between motor output shaft, elastic coupling flexible coupling, jack shaft, spline housing and reducer input shaft.The wear-resisting grade of elastic coupling flexible coupling spline is higher than the wear-resisting grade of motor output shaft, jack shaft, and the area of contact between the sliding friction pair that has of elastic coupling flexible coupling itself is much larger than the area of contact of elastic coupling flexible coupling and motor output shaft, jack shaft.Area of contact is little, and surface friction drag is just little, just slides easily, so the just wearing and tearing distortion easily of the spline of motor output shaft, jack shaft.Splined shaft after the wearing and tearing distortion is difficult in time enter in the elastic coupling flexible coupling, and bridge motor just can not in time be braked, and this has just caused stopping distance to exceed standard.
Summary of the invention
The utility model provide a kind of sliding friction pair can with the timely opening and closing of the rotor of conical rotor motor, ensure the electric wire hoist elastic coupling flexible coupling that electric wire hoist runs well.
The purpose of this utility model is achieved in that a kind of electric wire hoist elastic coupling flexible coupling, comprises elastic coupling flexible coupling 4, is provided with pressure spring 9 between kinetic friction of elastic coupling flexible coupling 4 secondary 7 and the static friction pair 8.
Electric wire hoist elastic coupling flexible coupling provided by the utility model, by between and the static friction pair secondary spring being set in the kinetic friction of electric wire hoist elastic coupling flexible coupling, during the conical rotor motor outage, rotor moves to big end under spring action, the secondary just inwardly motion of the kinetic friction of elastic coupling flexible coupling, pressuring spring shrinks, and rotor drags the brake sticking brake of small end; During energising, electromagnetic force overcomes the active force of spring, rotor is moved to small end, band-type brake unclamps, rotor enters working state, the just outwards motion under the effect of spring of the sliding friction pair of elastic coupling flexible coupling is eliminated motor output shaft and is shunk the axial clearance that produces, and has ensured the electric wire hoist normal operation effectively.
Description of drawings
Fig. 1 is the utility model embodiment schematic representation.
Fig. 2 is a kind of structural representation of electric wire hoist.
Below in conjunction with accompanying drawing the utility model is done detailed explanation.
Embodiment
Shown in Figure 2: as to establish a spring 9 between kinetic friction of electric wire hoist elastic coupling flexible coupling secondary 7 and the static friction pair 8.The size of pressure spring 9 elastic force is just in time pushed kinetic friction pair 7 open.
In conjunction with Fig. 1,2, working procedure of the present utility model: electric wire hoist generally is that the rotation by reel 2 fulfils assignment.During conical rotor motor 1 outage, secondary 7 pressure springs 9 of the kinetic friction of elastic coupling flexible coupling 4 slide in static friction secondary 8; During energising, the kinetic friction pair 7 of elastic coupling flexible coupling 4 is under the thrust of pressure spring 9, outside static friction secondary 8, slide, in the entire work process, the relative position of conical rotor motor 1, elastic coupling flexible coupling 4, jack shaft 5, spline housing 6 and retarder 3 all is not subjected to displacement variation, is subjected to displacement just kinetic friction pair 7, the static friction pair 8 of elastic coupling flexible coupling 4 of variation.
