The utility model overcomes the defect s of the existing products, and has the characteristics of reasonable structure, simple preparing process, high working reliability, etc.
Description
The utility model relates to a kind of movable bearing support that supports pipeline or equipment.
Present low coefficient of friction sliding support mainly contains three classes:
One class is to adopt screw to do the low coefficient of friction sliding support of friction pair on steel plate the filled polytetrafluoroethylene blockage, and its shortcoming is: 1) the loosening back of set screw filled polytetrafluoroethylene square easily comes off.2) in case set screw does not have tightening nuts to exceed the filled polytetrafluoroethylene square, nut will scratch another friction pair.3) processed complex.
Second class is that the filled polytetrafluoroethylene nahlock is embedded on the steel plate that preformed hole is arranged low coefficient of friction sliding support as friction pair, its shortcoming is: 1) bad as the tolerance control of preformed hole, the teflon nahlock easily comes off, 2) the requirement on machining accuracy height of preformed hole, Economy is relatively poor.
The 3rd class is directly to be encased inside between the upper and lower substrate with the big plate of teflon, and its shortcoming is: the big plate of teflon is taken root nowhere, upper and lower substrate relative movement several times, the big plate of teflon both skidded off between upper and lower substrate, made stent failure; This product reliability is poor.
The purpose of this utility model is exactly to provide a kind of rational in infrastructure in order to address the above problem, and what reliability was high does the low coefficient of friction sliding support of friction pair with the teflon sintered plate.
Technical solution of the present utility model:
A kind of low coefficient of friction sliding support of making friction pair of the teflon sintered plate, it includes conduit saddle, upper substrate, mirror finished stainless steel plate and infrabasal plate, its conduit saddle is used to support pipeline or equipment, it is characterized in that between mirror finished stainless steel plate and infrabasal plate, being provided with sintered plate, this sintered plate is made up of the polyfluortetraethylene plate on upper strata and the steel plate of lower floor, they are an integral body, and steel plate and infrabasal plate are fixed with one, and polyfluortetraethylene plate and mirror finished stainless steel plate lower surface are slidingly connected.
The utility model compared with prior art, key is that wherein a friction pair has adopted teflon and steel plate sintering compound sintered plate (abbreviation sintered plate) together, the processing of sintered plate is with polyfluortetraethylene plate pressure sintering composite sheet together with a kind of special process, this sintered plate peeling strength at normal temperatures can reach more than the 70N/cm, shear strength can reach more than the 4MPa, and its good characteristic provides reliable assurance for the utility model.The utility model has overcome the shortcoming of above-mentioned three class existing products, has rational in infrastructurely, and processing is simple, and is good in economic efficiency, characteristics such as functional reliability height.
The utility model is described in further detail below with reference to accompanying drawing.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a sintered plate structural representation of the present utility model;
Fig. 3 is the welding schematic representation of the utility model sintered plate and infrabasal plate.
As Fig. 1,2, the utility model includes conduit saddle 1, upper substrate 2, mirror finished stainless steel plate 3 and infrabasal plate 5, its conduit saddle 1 is used to support pipeline 6 or equipment, characteristics of the present utility model are, be provided with sintered plate 4 between mirror finished stainless steel plate 3 and infrabasal plate 5, this sintered plate 4 is made up of the polyfluortetraethylene plate 7 on upper strata and the steel plate 8 of lower floor, and they are an integral body, steel plate 8 is fixed with one with infrabasal plate 5, and polyfluortetraethylene plate 7 is slidingly connected with mirror finished stainless steel plate 3 lower surfaces.
During the utility model actual fabrication, the compound sintered plate 4 that steel plate 8 sintering that polyfluortetraethylene plate 7 that can 2mm is thick and 3mm are thick form together, be welded on the infrabasal plate 5 of bearing as a friction pair, another friction pair is welded on the upper substrate 2 of bearing with mirror finished stainless steel plate 3, this upper substrate 2 and conduit saddle 1 welding, conduit saddle 1 the pipeline 6 final and user welds.Polyfluortetraethylene plate 7 surfaces produce slide relative with mirror finished stainless steel plate 3 surfaces, and the friction factor between it is 0.06～0.1.Mirror finished stainless steel plate 3 adopts with upper substrate 2 and is interrupted welding, guarantees that mirror finished stainless steel plate 3 is smooth smooth, and sintered plate 4 adopts intermittently with infrabasal plate 5, intermittent welding, guarantees not have around smooth smooth, the polyfluortetraethylene plate 7 of sintered plate 4 to warp.Mirror finished stainless steel plate 3 forms friction pair with sintered plate 4.
In the utility model, the shape of sintered plate 4 and size depend on the magnitude of load of the 6 pairs of bearings of pipeline on the conduit saddle 1, and load is big, require the gross area of sintered plate 4 just big, otherwise just little.Correspondingly, sintered plate 4 can be an entire plate, also can be the discrete little individual plates of polylith, and the piece number that the sintered plate 4 among Fig. 1 and Fig. 3 is selected is four.
Claims (2)
1, a kind of low coefficient of friction sliding support of making friction pair of the teflon sintered plate, it includes conduit saddle, upper substrate, mirror finished stainless steel plate and infrabasal plate, its conduit saddle is used to support pipeline or equipment, it is characterized in that between mirror finished stainless steel plate and infrabasal plate, being provided with sintered plate, this sintered plate is made up of the polyfluortetraethylene plate on upper strata and the steel plate of lower floor, they are an integral body, and steel plate and infrabasal plate are fixed with one, and polyfluortetraethylene plate and mirror finished stainless steel plate lower surface are slidingly connected.
