Description
Technical field
The utility model relates to a kind of drg, relates in particular to a kind of elevator traction chance drg.
Background technology
Friction brake/the power-transfer clutch of prior art is being braked or during transferring power, capital produces larger impact and vibrations because positive pressure being applied to the body surface contacting with friction lining, therefore can affect the life-span of part and produce very large noise, harm people's physical and mental health when braking.When should brake/clutch changing into attracting state from braking mode or transferring power state, also can produce large impact and large noise because larger electromagnetic attraction of needs is retracted.In order to address this problem, people have installed the auxiliary devices such as damping element and friction lining on drg, can reduce to a certain extent impact damage and noise nuisance, but the auxiliary devices such as these damping elements and friction lining are due to simple in structure, there is lubricated wet goods utilization defect not fully, increased the heat producing in friction process.
Utility model content
The purpose of this utility model is to provide a kind of elevator traction chance drg, can make full use of lubricating oil, reduces the heat and the wearing and tearing that in friction schedules, produce, solves the shortcoming that prior art exists.
The utility model adopts following technical scheme to realize:
A kind of brake for traction machine of elevator, this drg has a disk body, described disk body is fixedly connected with armature by screw, hyoplastron is installed on armature, on described hyoplastron, be provided with friction lining, armature is corresponding with a brake wheel, it is characterized in that, described friction lining is discoid, upper surface and/or lower surface at friction lining have oil groove, described oil groove is uniformly distributed around the center of circle of friction lining, between adjacent oil groove, be provided with through hole, elastic-friction post is installed on through hole, the body of described elastic-friction post is cylindrical, the two ends of elastic-friction post are the force side of stretching out upper surface and/or the lower surface of friction lining.
Further, the diameter of described force side is greater than the diameter of the body of elastic-friction post.
Further, described force side is shaped as elliposoidal.
Useful technique effect of the present utility model is: elastic-friction post and oil groove are uniformly distributed on friction lining, scientifically be provided with the structure of oil groove, make drg when contact friction, utilize heat that friction lining heating produces by the lubricating oil expanded by heating in oil groove and overflow oil groove, surface at whole friction lining forms oil film, particularly can on the force side at elastic-friction post two ends, form oil film, thereby the wearing and tearing of elastic-friction post are reduced, the life-span of friction lining is extended, and reduced the noise of friction lining, reduced the fault rate of drg.

The specific embodiment
By the description to embodiment below; to more contribute to public understanding the utility model; but the given specific embodiment of applicant can't be considered as to the restriction to technical solutions of the utility model, any definition to parts or technical characterictic change and/or to integral structure do form and immaterial conversion all should be considered as the protection domain that the technical solution of the utility model limits.
Brake for traction machine of elevator as shown in Figure 1 to Figure 3, this drg has a disk body, and disk body is fixedly connected with armature 1 by screw, hyoplastron 3 is installed on armature 1, hyoplastron 3 is arranged on armature 1 by screw 2, is provided with friction lining 4 on hyoplastron 3, and armature 1 is corresponding with a brake wheel 5.Friction lining 4 is circular in the present embodiment, certainly friction lining 4 can be set in other embodiments solid discoid, friction lining 4 further can also be improved to lamination layer structure, as two friction linings are formed to a friction plate assembly by mode bonding or that screw is fixing, further increase the braking effect of friction lining.The brake action of drg is to be mainly achieved by friction lining 4, and armature 1 to brake wheel 5 transmitting torques, is realized the object of safety arrestment by friction lining 4.The materials of friction lining 4 itself can be made by steel disc, and a friction lining is set on it, and the mode by bonding, riveted joint or sintering realizes lamination layer structure, and the lining that wherein rubs can be selected rubber layer.Because friction lining 4 is high speed rotating at work, thus friction lining 4 the combination with brake wheel 5 with in separated process, can produce a large amount of heats, the temperature of self can raise, this phenomenon is kept away and can not be exempted from.From saving the angle of manufacturing cost, should control the thickness of friction lining 4, can either accomplish material-saving, can realize again good braking effect and reach best radiating effect.Through many experiments, prove, when the thickness of friction lining is 5cm～8cm, the effect of friction braking is best, manufacturing cost can also be reduced simultaneously, and reach radiating effect relatively preferably, so thickness that can single friction lining is set to 5cm～8cm, or the integral thickness of friction plate assembly is set to 5cm～8cm.Upper surface and/or lower surface at friction lining 4 have oil groove 6, oil groove 6 is uniformly distributed around the center of circle of friction lining 4, between adjacent oil groove 6, be provided with through hole 7, elastic-friction post 8 is installed on through hole, the body of elastic-friction post 8 is cylindrical, the two ends of elastic-friction post 8 are to stretch out the upper surface of friction lining and/or the force side of lower surface 9, and the diameter of force side 9 is greater than the diameter of elastic-friction post body, and the shape of force side 9 is preferably elliposoidal.Elastic-friction post 8 can be selected the elastic-friction post of quality of rubber materials, utilizes the favorable elasticity deformability of rubber column that enough friction force are provided, or selects the material with elastic deformation ability similar to rubber column and friction coefficient.When friction lining 4 comes in contact with brake wheel 5, first there is elastic deformation in the force side 9 of elastic-friction post 8, force side 9 produces friction force with brake wheel 5, after 9 bendings of force side, the friction lining of friction lining 4 or friction lining body can bump and form friction force with brake wheel 5 again, from face, reach the object of braking, because friction lining when contacting 4 can generate heat, so the lubricating oil in oil groove 6 can overflow oil groove 6 because of the characteristic of fluid expanded by heating, upper surface and/or lower surface at whole friction lining 4 form oil film, particularly between the force side 9 of elastic-friction post 8 and friction lining 4 bodies, form oil film, thereby the wearing and tearing of elastic-friction post 8 are reduced, the difficult generation vibrations of whole friction braking process and the noise of drg are less.
In another embodiment, within elastic-friction post 8 is not fixed on through hole 7, but detachable installation, after the long-time use of drg, impaired elastic-friction post 8 can be disassembled from through hole 7 like this, change the elastic-friction post 8 of same size, and do not need to change whole friction lining 4.Because the volume of elastic-friction post 8 is little, consumptive material is few, change simple and convenient, therefore the manufacture of brake for traction machine of elevator, maintenance cost are reduced.
Certainly; the utility model can also have other various embodiments; in the situation that not deviating from the utility model spirit and essence thereof; those of ordinary skill in the art can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the utility model.
