Abstract
The present invention discloses an environment-protecting type elastic metal plastic bearing liner. It includes steel brearing base, on the steel bearing base a metal wire elastic pad is firmly combined, on the metal wire elastic pad a surface plastic layer is inlaid, the described surface plastic layer is made of modified polytetrafluoroethylene powder material, said powder material is prepared by using (by wt%) 2-8% of aramid fibre, 20-30% of polyphenyl ester or polyimide and the rest is polytetrafluoroethylene.
Description
Technical field:
The present invention relates to a kind of hydraulic generator unit heavy-loaded thrust bearing elastic metal plastic bearing, especially a kind of environment protection elastic metallic plastic bush.
Background technique:
At present, elastic metal plastic bearing is equipped with steel tile base, and soldering has the compound tiling of metallo-plastic on steel tile base.
Have with the immediate prior art of present patent application technology that China Patent No. is 90103367.7, name is called the patent of invention of " elastic thrust block and manufacture method ", disclosed technological scheme is " being porous material with the tin bronze, is stuffing with surface and the plumbous modified surface plastics that mix " elastic force of making watt and preparation method thereof." its tin bronze porous material is that the tin bronze wire spiral spring of 0.4～0.6mm constitutes by some diameters; the degree of depth that its modified surface stuffing infiltrates in cushion is 1/2～1/3 of a cushion; the thickness of surface wear-resistant layer is 0.5～3mm; lead accounts for 5～40% in modified Teflon, and teflon accounts for 60～90 (weight percentages) ".This patented technology main purpose is the uneven phenomenon of contact pressure that is produced for thrust position mechanically deformation and the thermal distortion that solves existing hydraulic generator unit, but the elastic thrust block that provides a kind of tiling mechanical temperature distortion self to adjust, simultaneously in order to improve the product friction and wear behavior better, plastic layer is carried out modification handles, exist following problem:
1. owing to contained the enhancing and the metallic lead of wear-resisting effect in the surfacing,, be easy to generate shaft current and damage bearing shell so surfacing has electric conductivity.For this reason, bearing shell that uses on the existing hydraulic generator unit and associated components all need adopt insulation measures such as dead ring is installed, and make product structure complexity and cost height;
2. the use befouling environment of metallic lead is unfavorable for environmental protection.
Summary of the invention:
The present invention is easy to generate shaft current and environmental pollution problem in order to solve existing in prior technology, provide a kind of and can overcome the shaft current Issues on Static Electrification, satisfy environmental requirement, have low friction, the wear-resisting environment protection elastic metallic plastic bush that undermines stronger rigidity again.
Technical solution of the present invention is: a kind of environment protection elastic metallic plastic bush, comprise steel tile base 1, on steel tile base 1, be firmly combined with wire elastic pad 2, be embedded with surperficial plastic layer 3 on the wire elastic pad 2, described surperficial plastic layer 3 is the modified Teflon powder, and prepared by following material and weight percentage: aramid fibre 2～8, polybenzoate or polyimide 20～30, teflon are surplus.
Described aramid fibre preferably accounts for 3～4% of gross weight.
Surfacing of the present invention is unleaded modified Teflon plastic layer, and reasonably prescription not only helps environmental protection, and its abrasion resistance properties and mechanical property also are further enhanced.Unleaded modified Teflon plastic layer no longer has electric conductivity simultaneously, can not damage bearing shell owing to the generation of shaft current, need not to install on bearing shell and associated components insulation facilities such as dead ring on the hydraulic generator unit, product structure is simple, can reduce cost.
Description of drawings:
Fig. 1 is the structural representation of the embodiment of the invention.
Embodiment:
Embodiment 1:
A. make wire pads with prior art;
The teflon that b. will account for the aramid fibre of total weight percent 2～8, the polybenzoate that accounts for total weight percent 20～30 or polyimide and surplus mixes, raw material can be inserted in the cartridge type mixing machine, select rotating speed 100～150r, mix getting final product in 20～50 minutes;
C. with mixed powder spreading on wire elastic pad 2 blanks, mold pressing is combined into the tiling blank according to a conventional method;
D. sintering tiling blank according to a conventional method is formed in the tiling that is embedded with surperficial plastic layer 3 on the wire elastic pad 2;
E. with the tiling soldering on steel tile base 1, promptly make product as shown in Figure 1.
Embodiment 2:
Other is with embodiment 1, and just aramid fibre accounts for 3～4% of gross weight, and polybenzoate or polyimide account for 23～26% of gross weight, and surplus is a teflon.
Claims (2)
