Abstract
The utility model relates to a spray coated external framework oil seal which is composed of an oil seal metal framework (1), a rubber layer (2) which is compounded on the framework and a fluid dynamic backflow ripple (3) on the inner side of the rubber layer. The utility model is characterized in that the upper part of a top circle (4) of the metal framework is inwards folded to form a metal framework flanging which is provided with a guide angle (5), and the top circle (4) of the metal framework is sprayed with one layer of rubber mucilage (6) which is fixed on the top circle (4) of the metal framework through high temperature sulfidation. The utility model has the advantages of little rubber content of the oil seal, low manufacture cost, reliable sealing performance, good concentricity, good heat radiation performance, and long service life.
Description
The utility model is a kind of novel oil sealing, belongs to the technical field that Sealing is made.
Present oil sealing both domestic and external mostly is rubber cladding formula outside framework oil seal, and this oil sealing is to be surrounded by certain thickness rubber layer in the oil tight skeleton outside, and the top of the rubber layer on the skeleton circumference angle that invagination is certain in the middle of skeleton forms rubber flexible angle of deflection is installed.The oil sealing that has adopts the semi-showing type rubber framework grease seal, and the outer garden of this oil sealing skeleton Lower Half is compounded with rubber layer, first all skeleton be exposed conveying appliance.It installs angle of deflection is that the skeleton first half is cut the formation that has a certain degree, and is provided with fluid dynamic backflow line in the middle of each oil sealing inner ring rubber layer, and above-mentioned oil sealing is big with rubber mass, the manufacture cost height, and installing and locating is poor, weak heat-dissipating, concentricity is poor, and working life is short.
The purpose of this utility model provides a kind of spary coating type and exposes outside framework oil seal.This oil sealing low cost of manufacture, installing and locating is good, and thermal diffusivity is good, long service life.
For achieving the above object, the utility model is by oil sealing metal frame (1), being compounded in the rubber layer (2) on the metal frame (1) (on garden outside the oil sealing metal frame (4) not composite rubber layer) and the fluid dynamic backflow line (3) of rubber layer inboard forms, it is characterized in that it is 15～30 degree that the inside flanging in top, garden outside exposing the oil sealing metal frame (4) constitutes its inside flanging guiding angle of metal frame flanging installation angle of deflection (5), the height of angle of deflection part is 20%～35% of metal frame (a 1) height, the thickness of skeleton flanging part is attenuate or keep former skeleton thickness suitably, adopt above-mentioned angle of deflection, make oil sealing guiding is installed accurately, reliably, positioning performance is good.Go up spraying one deck rubber slurry using (6) in the outer garden (4) of oil sealing metal frame (1), this rubber slurry using is fixed on the garden outside the skeleton (4) through high temperature vulcanized, and the thickness of dry film of its sprayfused coating THICKNESS CONTROL after sulfuration is 0.05～0.10 millimeter.Above-mentioned rubber sprayfused coating is even, and is few with rubber mass, low cost of manufacture, and rubber adhesion height, sealability is reliable, rapid heat dissipation, good concentricity, long service life.
Because in the technique scheme, adopted the inside flanging in metal frame Wai Yuan top and the garden sprays rubber layer skeleton outside technological scheme, make whole oil sealing, rubber consumption is few, low cost of manufacture, sealability is reliable, good concentricity, rapid heat dissipation, long service life.
The utility model is described in further detail below in conjunction with accompanying drawing and specific embodiments.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is an A-A of the present utility model portion sectional view.
Each label symbol is among the figure: 1, oil sealing metal frame, 2, rubber layer, 3, fluid dynamic backflow line; 4, the outer garden of oil sealing metal frame; 5, the metal frame flanging is installed angle of deflection;
6, rubber slurry using.
The utility model is by oil sealing metal frame (1), being compounded in the rubber layer (2) on the metal frame (1) (on garden outside the oil sealing metal frame (4) not composite rubber layer) and the fluid dynamic backflow line (3) of rubber layer inboard constitutes, cutting is carried out at the position on top, garden (4) 30% outside above-mentioned oil sealing metal frame, keeping its skeleton is 1/3 of skeleton thickness, then inside flanging 25 degree of skiving back skeleton, make it become the metal frame flanging angle of deflection (5) is installed, go up with spraying machine spraying one deck rubber slurry using (6) in garden outside the oil sealing metal frame (4), this rubber slurry using is fixed on the garden outside the metal frame (4) after the fluidisation typing in high temperature, and the thickness of dry film of its sprayfused coating THICKNESS CONTROL after sulfuration is 0.05～0.10 millimeter.According to the above, just can constitute the utility model spary coating type and expose outside framework oil seal.
Claims (1)
- A kind of spary coating type exposes outside framework oil seal, by oil sealing metal frame (1), being compounded in the rubber layer (2) on the skeleton (on garden outside the oil sealing metal frame (4) not composite rubber layer) and the fluid dynamic backflow line (3) of rubber layer inboard forms, it is characterized in that exposing oil sealing metal frame foreign country (4) top inside flanging formation metal frame flanging installation angle of deflection (5), its inside flanging guiding angle is 15～30 degree, the height of angle of deflection part is 20%～35% of metal frame (a 1) height, and the thickness of skeleton flanging part is attenuate or keep former skeleton thickness suitably; Go up spraying one deck rubber slurry using (6) in the outer garden (4) of oil sealing metal frame (1), this rubber slurry using is fixed in after high temperature vulcanized on the garden outside the skeleton (4), and the thickness of dry film of its sprayfused coating THICKNESS CONTROL after sulfuration is 0.05～0.10 millimeter.
