Abstract
The utility model provides a plastics oil blanket wear ring that floats, includes floating seal ring body, its characterized in that: the floating seal ring body is moulded plastics by engineering plastics and is formed. Be provided with inside " C " shape groove of antifriction metal (AFM) ring embedding floating seal ring body in the well lower part on the outer edge of floating seal ring body, the sealing weld of " C " shape inslot has a wear -resisting metal material, still sets up the oil -feed tank of the oil feed of being convenient for in the below in " C " shape groove. The utility model discloses a technique effect: the floating seal ring body adopts engineering plastics to mould plastics and forms, has replaced current metal floating seal ring body, and is energy -concerving and environment -protective, save material cost, manufacturing cost. Choose the more excellent wear -resisting metal material of wear resistance for use, " C " shape inslot is advanced in the sealing weld, as floating seal ring's friction working face. Can prolong the wear -resisting time that the oil blanket that floats encircled greatly like this, improve the life of product. The floating seal ring of this kind of production of moulding plastics is than metal floating seal ring, and production efficiency obviously promotes.
Description
Technical field
The utility model belongs to mechanical field, particularly relates to a kind of plastics float grease seal wear ring.
Background technique
Floating seal is the one of motive sealing, good sealing effect is had in the harsh environments such as many coal dusts, silt, aqueous vapor, be a kind of mechanical seal of compact type, be generally used in the structures such as handpiece of scraper conveyer (tail) chain wheel assembly, loading mechanism for tunneling machine, the left and right cutting drum of continuous miner and retarder.The structure of float grease seal is generally made up of a pair wear-resisting metal ring (floating sealing ring) and a pair rubber ring, is assemblied in Special seal cavity (floating sealing base) and uses.An one dynamic quiet floating sealing ring is when relatively rotating, the end face contacted forms the sealing surface perpendicular to axis, rubber ring produces resiliently deformable by compression in the Seal cage formed with floating sealing base, seal face is under the resilient force of rubber ring, produce certain face pressure, now, at the up one-tenth of seal face and the substantially complete oil film keeping one deck very thin, make between two seal faces, to be in boundary friction or semi-fluid friction operating mode, when seal face is along with relatively rotating of floating sealing ring during relative sliding, oil film serves seal action.
Existing floating sealed seals by two metal floating sealing ring faying surfaces, metal floating sealing ring is not wear-resistant, floating sealing ring faying surface is after wearing and tearing for a long time, faying surface gap can increase, lubricant oil can flow to the external world because of box house pressure difference, produce ooze, the seal failure phenomenon such as leakage of oil, carry out changing, keep in repair all very difficult, and metal floating sealing ring manufacture cost is higher, production difficulty is comparatively large, efficiency is low.
Model utility content
The utility model patent provides a kind of plastics float grease seal wear ring for the problems referred to above, replaces metal with engineering plastics, can larger reduction cost of production, improves product quality and production efficiency.
The technical solution of the utility model: a kind of plastics float grease seal wear ring, comprise wear ring body, it is characterized in that: described wear ring body is injection molded by engineering plastics, wear ring body offers the fluting for accommodate O-shaped rubber seal, " C " shape groove embedding wear ring body interior is provided with in the middle and lower part of the outer of wear ring body, in " C " shape groove, sealing weld has wear-resistant metal material, also offers in the below of " C " shape groove the oil-feed tank being convenient to oil-feed.
Described " C " shape channel opening is outside and concordant with outer.
The internal surface of described " C " shape groove is for ease of the iron sheet of sealing weld wear-resistant metal material.
Technique effect of the present utility model: wear ring body adopts engineering plastics injection molded, instead of existing metal body, energy-conserving and environment-protective, and save cost of production, " C " shape ring of embedding is tamped by built-up welding and becomes antifriction metal (AFM) ring; This wear ring is that the antifriction metal (AFM) built-up welding of selecting wear-resisting property more excellent becomes oil sealing frictional contact surface, greatly can extend wear time, improves the working life of product.The design of oil-feed tank can ensure that lubricant oil can to the supply of friction fit anchor ring, prevent the dry grinding between abrasion-resistant metal ring faying surface, strengthen oil sealing effect and working life, the floating sealing ring that injection moulding is produced can significantly promote compared with the floating sealing ring manufacturing efficiency of metallic material, reduces cost of material and cost of production.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Number in the figure represents respectively: 1-wear ring body, 2-fluting, 3-outer, 4-" C " shape grooves, 5-wear-resistant metal material, 6-oil-feed tank.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated:
As shown in Figure 1: a kind of plastics float grease seal wear ring, comprise wear ring body 1, it is characterized in that: described wear ring body 1 is injection molded by engineering plastics, wear ring body 1 offers the fluting 2 for accommodate O-shaped rubber seal, " C " shape groove 4 embedding wear ring body 1 inside is provided with in the middle and lower part of the outer 3 of wear ring body 1, in " C " shape groove 4, sealing weld has wear-resistant metal material 5, also offers in the below of " C " shape groove 4 oil-feed tank 6 being convenient to oil inlet lubricating rubbing surface.
Described " C " shape groove 4 outward opening and concordant with outer 3.
The internal surface of described " C " shape groove 4 is for ease of the iron sheet of sealing weld wear-resistant metal material 5.
Thick band iron skin is selected to be bent into " C " shape, opening towards the annulus of side, and is welded into closed full circle shape, controls round iron skin planeness through shaping;
The wear-resistant metal material that sealing weld is selected in " C " shape groove, fills up the built-up welding of " C " shape groove;
By " C " shape groove good for sealing weld, carry out the processing of end face barreling;
" C " shape groove is placed in desired location in injection machine mould chamber, injection moulding, " C " shape groove is embedded in float grease seal ring body.
During use, a pair wear ring correspondence is arranged, " C " shape channel opening is relative, the wear-resistant metal material relative movement at " C " shape channel opening place during seal friction, rub, owing to offering oil-feed tank in the below of " C " shape groove, lubricant oil can enter between two wear rings smoothly, forms good oil sealing effect.
A kind of plastics float grease seal wear ring of the present utility model, wear ring body adopts engineering plastics injection molded, instead of existing metal body, energy-conserving and environment-protective, save cost of production, the wear ring that the antifriction metal (AFM) built-up welding of selecting wear-resisting property more excellent is made carries out rubbing contact, greatly can extend wear time, improve the working life of product, the design of oil-feed tank can ensure the supply of lubricant oil, prevent the dry grinding between wear ring body, strengthen oil sealing working life, injection moulding produce wear ring body comparatively metal ring manufacturing efficiency can significantly promote, cost significantly reduces.
