Abstract
The utility model relates to a mechanical sealing oil retainer for a drum-type coal mill and a large-sized turning machine, and a sealing oil retainer, in particular to a sealing oil retainer used on large-sized machinery like a drum-type coal mill and a large-sized turning machine. The sealing oil retainer comprises a stationary ring(1) and a movable ring(2), both of which are circular ring bodies made of elastic materials. Bolt holes(3) are evenly distributed on the head face of the stationary ring(1); and an extension body(4), hydraucone-shaped outward, is arranged at the outer edge of one end of the movable ring(2). The sealing oil retainer has the advantage of good sealing effect and can effectively solve the problems of untight sealing and serious oil leakage of the large-sized turning machine and the drum-type steel ball coal mill.
Description
Technical field
The utility model relates to the sealing flinger ring, is specifically related to be applied in the sealing flinger ring on the big machineries such as cartridge type coal pulverizer and large-scale favourable turn.
Background technique
The sealing means that original cartridge type coal pulverizer and large-scale favourable turn are adopted all is to adopt felt filler, gland seal, because installing to scrape watt causes the concentricity of cartridge type coal pulverizer to have error, thereby also there is corresponding error in filler space, the broadband of felt filler can not be assembled in the error ratio, sealing effect is poor, site environment is more abominable in addition, is in operation to be rotated action of centrifugal force, causes equipment oil leakage more serious.It more than is the common fault of countries in the world cartridge type coal pulverizer and large-scale favourable turn.
The model utility content
Technical problem to be solved in the utility model is: cartridge type coal pulverizer and large-scale favourable turn mechanical seal flinger ring that a kind of good sealing effect is provided.
Technical solution of the present utility model is: it comprises stationary ring and rotating ring, and stationary ring and rotating ring all are cirque body of being made by elastic material, the uniform bolt hole of stationary ring end face, and the outer rim place of rotating ring one end is provided with the stretching, extension body that outwards is bell mouth shape.
Technique effect of the present utility model is: it has advantage of good sealing effect, can effectively solve barrel-shaped steel ball mill and large-scale favourable turn is poorly sealed, leakage of oil is serious problem.
Description of drawings
Accompanying drawing is the structural representation that partly cuts open of the present utility model.
Embodiment
As shown in drawings, the cartridge type coal pulverizer of present embodiment and large-scale favourable turn mechanical seal flinger ring, comprise stationary ring 1 and rotating ring 2, stationary ring 1 and rotating ring 2 all are cirque body of being made by elastic material, the uniform bolt hole 3 of stationary ring 1 end face, the outer rim place of rotating ring 2 one ends is provided with the stretching, extension body 4 that outwards is bell mouth shape.
One end of described stationary ring 1 is in being provided with the annular protrusion 5 that is bell mouth shape near inner radius.
The inner edge of described stationary ring 1 is provided with sealing lip limit 6.
The periphery of described rotating ring 2 is provided with V-ring groove 7, and V-ring groove 7 can be established a plurality of, and V-ring groove 7 collar extensions are lower than stretching, extension body 4.
The inner edge of described rotating ring 2 is provided with sealing lip limit 6.
The outer rim of described stretching, extension body 4 is provided with sealing lip limit 6.
The stationary ring 1 of present embodiment and rotating ring 2 adopt compounded rubber or polyurethane to make.
Present embodiment is when using, process the gland 8 and the foundation ring 9 of ring-type as shown in drawings earlier, foundation ring 9 can be fixing by welding, also can be directly and bearing support process together, be respectively equipped with on gland 8 and the foundation ring 9 and corresponding open-work and the tapped hole of stationary ring 1 bolt hole 3.During assembling, rotating ring 2 is enclosed within on the axle, and stationary ring 1 is pressed on the foundation ring 9 by gland 8 by bolt, and stationary ring 1 is relative with the horn mouth of rotating ring 2, and the horn mouth of rotating ring 2 is enclosed within the horn mouth periphery of stationary ring 1.
The utility model design is ingenious, installation is simple, maintenance is convenient, made full use of the design of action of centrifugal force and horn mouth shape, make its sealing reach comparatively desirable effect, its sealing effect can guarantee an overhaul phase, if adopt better abrasion resistant polyurethane made to become the sealing flinger ring, then can prolong its working life greatly.The utility model is fit to present employed cartridge type coal pulverizer in countries in the world and large-scale favourable turn mechanical seal needs, and the exploitation that is suitable for new product reaches the transformation to existing equipment, has filled up the blank of cartridge type coal pulverizer and large-scale favourable turn mechanical seal.
