Abstract
The utility model discloses a calathiform gasket comprises top structure, transition connection structure, polycrystalline substance that continuous thickness is the same in proper order, top structure centre is provided with the mounting hole, the top structure transition connection structure the polycrystalline substance has a same center pin, and with the center pin collineation of mounting hole, the top structure with the polycrystalline substance is the ring structure together, transition connection structure longitudinal section is conical, is used for connecting the top structure with the polycrystalline substance, calathiform gasket's gross thickness compares for 1 with the diameter size of mounting hole: 0.5 -0.8. The utility model has the advantages that the not enough of flat shim and drum -type gasket has been compensatied. The flat shim of comparing, the utility model discloses possess the stopping effect, and increased the lifting surface area, the drum -type of comparing gasket, the utility model discloses have bigger lifting surface area, disperseed the local pressure to winnowing pan installation position.
Description
Technical field
The utility model relates to fastening piece match equipment, specifically a kind of stopping shim.
Background technique
Noria is used for the vertical transport of powdery, granular and lump material, and its main working parts is elevator belt and winnowing pan.Winnowing pan is for holding the material of lifting, and elevator belt is used for the transmission of continuance lifting power.Fixing elevator belt and winnowing pan mainly adopt screw fastening, and screw mainly needs supporting nut and pad.
Because in lift running, winnowing pan constantly can be subject to material impact, nut loosening is easily caused to cause winnowing pan to come off, so nut retaining requires just higher than the fastening piece of other occasions.And, when winnowing pan stressed excessive time, nut, as fixing tight, very easily pull, causes winnowing pan to break from winnowing pan mounting hole.
At present, the domestic winnowing pan fastening means generally adopted is the combination of screw, nut, compression spring and flat gasket or drum type spacer.This configuration can not meet the locking requirement of winnowing pan under heavy duty or HI high impact environment.Flat gasket lifting surface area is too small, causes nut to pull from winnowing pan hole, and traditional drum type spacer is stressed concentrated, easily cause winnowing pan line stressed, thus it is bad to cause winnowing pan to draw.
Model utility content
Model utility object: for the problems referred to above, the purpose of this utility model is to provide a kind of in bowl-type, and lifting surface area is large, can the pad of effective retaining.
Technological scheme: a kind of bowl-type pad, be made up of the identical top structure of continuous print thickness, transition connecting structure, polycrystalline substance successively, described top structure center is provided with mounting hole, described top structure, described transition connecting structure, described polycrystalline substance have identical central shaft, and with the central shaft conllinear of described mounting hole; Described top structure and described polycrystalline substance are all circle structure, and described transition connecting structure longitudinal section is conical, in order to connect described top structure and described polycrystalline substance; The total thickness of bowl-type pad is 1:0.5-0.8 with the ratio of the diameter dimension of mounting hole.
Further, in order to make pad have larger lifting surface area, the described width at polycrystalline substance edge is 1:7-9 with the ratio of the diameter dimension of polycrystalline substance, and the diameter of described mounting hole is 1:3-4 with the ratio of the diameter dimension of described polycrystalline substance.
Beneficial effect: compared with prior art, the utility model has the advantages that the deficiency that compensate for flat gasket and drum type spacer.Compare flat gasket, the utility model possesses retaining effect, and increases lifting surface area; Compare drum type spacer, the utility model has larger lifting surface area, has disperseed the local pressure to winnowing pan installation position.When winnowing pan is subject to material impact or discharging shake, all the time can ensure that nut has metastable tension force, guarantee that nut does not produce loosening, and ensure that certain lifting surface area compresses winnowing pan surface all the time, can effectively prevent because the compression of nut causes the material deformation at winnowing pan mounting hole position, significantly improve stability and the Security of winnowing pan use, improve the working life of elevator belt and the stability and high efficiency of equipment.
Accompanying drawing explanation
Fig. 1 is plan view of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further, these embodiments should be understood and be only not used in restriction scope of the present utility model for illustration of the utility model, after having read the utility model, the amendment of those skilled in the art to the various equivalent form of value of the present utility model has all fallen within the application's claims limited range.
As shown in Figure 1 and Figure 2, a kind of bowl-type pad, being made up of continuous print top structure 1, transition connecting structure 2, polycrystalline substance 3 successively, three's thickness is all identical.Top structure 1 and polycrystalline substance 3 are all circle structure, and top structure 1 middle is mounting hole 4.The longitudinal section of transition connecting structure 2 is conical, in order to connect top structure 1 and polycrystalline substance 3.The central shaft of top structure 1, transition connecting structure 2, polycrystalline substance 3 is identical, and with mounting hole 4 central shaft conllinear.
The middle-carbon steel that the utility model adopts elasticity good is shaping through mould punching.The diameter d of mounting hole 4 is 1: 3-4 with the ratio of the diameter D size of polycrystalline substance 3, and the edge horizontal width h of polycrystalline substance 3 is 1: 7-9 with the ratio of base diameter D size.Consider that pad must possess certain retaining fastening effect, total thickness H of the present utility model is 1: 0.5-0.8 with the ratio of the diameter d size of screw mounting hole 4.
The utility model product is larger than common flat gasket lifting surface area more concentrated, bottom has more the horizontal circular ring expanding lifting surface area, the acting in conjunction of attaching nut and compression spring, can ensure more effectively to fix winnowing pan within the scope of pad largest deformation, avoid the winnowing pan because material impact causes and screw loosening, ensure that equipment effective and safe runs.
