Description
Technical field
The present invention relates to the technical field of mechanical seal, specifically a kind of reduced form welded metal-bellows mechanical seal.
Background technique
Welded metal-bellows mechanical seal, as a kind of typical seal, has obtained comparing widely using.Meet the installation dimension of DIN24960 (mechanical seal standard), good with the interchangeability of other standard seal, possess the condition of batch production.The welded metal-bellows mechanical seal of present production, ring seat and tailstock adopt bar processing, and adopt cutting technology to complete, batch production efficiency is lower, and cost is high.
Summary of the invention
For the problems referred to above, the object of the present invention is to provide a kind of reduced form welded metal-bellows mechanical seal.Sealing improves the manufacturing efficiency of welded metal bellow, reduces cost of production, weight reduction.
To achieve these goals, the present invention is by the following technical solutions:
A kind of reduced form welded metal-bellows mechanical seal, comprise retainer, tailstock, bellows, ring seat and friction pair, wherein the two ends of bellows are connected to tailstock and ring seat, and described retainer to be sheathed on tailstock and to be connected with tailstock, and described friction pair is connected with ring seat.
The connecting end of described ring seat and friction pair is provided with shift fork, the end of described shift fork is radially inwardly equipped with projection, position corresponding with the projection of shift fork on the excircle of described friction pair is provided with anti-rotation groove, and the anti-rotation groove on the projection of described shift fork and friction pair is connected.Described shift fork is two.
The connecting end outer surface of described friction pair and ring seat is circumferentially provided with seam, described seam is arranged with 0 RunddichtringO II, described 0 RunddichtringO II is spacing by the shift fork in ring seat.
The inwall of described tailstock is provided with groove, is provided with 0 shape seal ring I in described groove.Described retainer is connected by Cock screw with tailstock, and described Cock screw is connected with revolving part.The two ends of described bellows are connected with tailstock and ring seat respectively by welding manner.Described tailstock and ring seat adopt corrosion resistant plate shaped by fluid pressure.
Advantage of the present invention and beneficial effect are:
1. the present invention changes the processing technology of welded metal bellow seal structural part, by with the shaping shaped by fluid pressure changing plate into of the Vehicle Processing of bar, reduces materials and processing cost, is conducive to universal use.
2. compact structure of the present invention, good sealing effect, convenient disassembly, long service life.
3. the present invention adopts shaped by fluid pressure production ring seat and tailstock, improves the manufacturing efficiency of welded metal bellow, and reduce cost of production, weight reduction, standardized designs, interchangeability is good, and using scope is more extensive.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Wherein: 1 is retainer, 2 is Cock screw, and 3 is 0 shape seal ring I, and 4 is tailstock, and 5 is bellows, and 6 is ring seat, and 7 is 0 shape seal ring II, and 8 is friction pair.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, the present invention includes retainer 1, tailstock 4, bellows 5, ring seat 6 and friction pair 8, wherein the two ends of bellows 5 are welded with tailstock 4 and ring seat 6 respectively, described retainer 1 to be sheathed on tailstock 4 and to be connected with tailstock 4 by Cock screw 2, and described Cock screw 2 is interior hexagon concave-end locking screw.The inwall of described tailstock 4 is provided with groove, is provided with 0 shape seal ring I3 in described groove.Described friction pair 8 is connected with ring seat 6, and described ring seat 6 is provided with two shift forks with friction pair 8 connecting end, and the end of each shift fork is radially inwardly equipped with projection, for relatively rotating of friction pair 8.On the excircle of described friction pair 8, the position corresponding with the projection of two shift forks is provided with anti-rotation groove, and the projection of described two shift forks is connected with the anti-rotation groove of two on friction pair 8 respectively.Described friction pair 8 and the connecting end outer surface of ring seat 6 are circumferentially provided with seam, described seam are arranged with 0 RunddichtringO II7, described 0 RunddichtringO II7 is spacing by two shift forks in ring seat 6.Described tailstock 4 and ring seat 6 adopt corrosion resistant plate shaped by fluid pressure, compact structure, and rotational stabilization is good.
Embodiment
Described ring seat 6 and tailstock 4 are by the thick corrosion resistant plate of 1mm by shaped by fluid pressure, and described ring seat 6 punching two place shift fork, is met the structure shape of seal request.Ring seat 6 and tailstock 4 one-body molded, be then divided into two bodies, friction pair 8 is arranged in ring seat 6, and static seal point seal by 0 shape seal ring II7, and torque drive passes through ring seat shift fork.The special weld bond place that ring seat 6 is processed in outer rim with bellows 5 welds.Bellows 6 plays sealing and elastic compensating effect.The special weld bond that tailstock 4 is processed in outer rim welds with bellows 5, and tailstock 4 and retainer 1 cooperation place process 3 through holes, and tailstock 4 is connected with retainer 1 by this through hole by Cock screw 2, prevents from relatively rotating, and 0 shape seal ring I is arranged in tailstock 4 inner wall trench.Retainer 1 is sleeved on tailstock 4, and Cock screw 2 is fastened on revolving part by the through hole on tailstock 4, ensures synchronous rotary.The moment of torsion of tailstock 4 passes through independently retainer 1 and completes, and retainer 1 adopts foundry goods, and bellows 5 adopts standard measure corrugated plate to weld, and friction pair 8 adopts silicon carbide material.Overall dimensions of the present invention is compact, favorable sealing property.Sealing configuration of the present invention is compact, and spin balancing is good, long service life, and processing cost is low, is conducive to promoting the use of.
