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 with respectively tailstock and ring seat, and described retainer is sheathed on tailstock and with tailstock and is connected, 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 projection and the friction pair of described shift fork is connected.Described shift fork is two.
On the connecting end outer surface of described friction pair and ring seat, along being circumferentially with seam, be arranged with O RunddichtringO II on described seam, described O RunddichtringO II is spacing by the shift fork in ring seat.
The inwall of described tailstock is provided with groove, is provided with O-ring seals 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 utility model and beneficial effect are:
1. the utility model changes the processing technology of welded metal bellow seal structural part, the Vehicle Processing moulding with bar is changed into the shaped by fluid pressure of plate, reduces materials and processing cost, is conducive to universal use.
2. the utility model compact structure, good sealing effect, convenient disassembly, long service life.
3. the utility model adopts shaped by fluid pressure production ring seat and tailstock, has improved the manufacturing efficiency of welded metal bellow, reduce production costs, and weight reduction, standardized designs, interchangeability is good, and using scope is more extensive.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1 is retainer, 2 is Cock screw, and 3 is O-ring seals I, and 4 is tailstock, and 5 is bellows, and 6 is ring seat, and 7 is O-ring seals II, and 8 is friction pair.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, the utility model comprises retainer 1, tailstock 4, bellows 5, ring seat 6 and friction pair 8, wherein the two ends of bellows 5 are welded with respectively tailstock 4 and ring seat 6, described retainer 1 is sheathed on tailstock 4 and by Cock screw 2 and is connected with tailstock 4, 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 O-ring seals 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 ends, and the end of each shift fork is radially inwardly equipped with projection, for relatively rotating of friction pair 8.Position corresponding with the projection of two shift forks on the excircle of described friction pair 8 is provided with anti-rotation groove, the projection of described two shift forks respectively with friction pair 8 on two anti-rotation grooves be connected.On the connecting end outer surface of described friction pair 8 and ring seat 6, along being circumferentially with seam, be arranged with O RunddichtringO II7 on described seam, described O 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 is by the thick corrosion resistant plate of 1mm by shaped by fluid pressure, and described ring seat 6 punching two place's shift forks, are met the structure shape of seal request.Ring seat 6 and tailstock 4 are one-body molded, are then divided into two bodies, and friction pair 8 is arranged in ring seat 6, and static seal point seals by O-ring seals II7, and torque drive is by ring seat shift fork.Ring seat 6 is welded at the special weld bond place of outer rim processing with bellows 5.Bellows 6 plays sealing and elastic compensating effect.Tailstock 4 welds at special weld bond and the bellows 5 of outer rim processing, 3 through holes of tailstock 4 and retainer 1 cooperation place processing, and Cock screw 2 is connected tailstock 4 by this through hole with retainer 1, prevent from relatively rotating, and O-ring seals 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, guarantees 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 the welding of standard measure corrugated plate, and friction pair 8 adopts silicon carbide material.The utility model overall dimensions compactness, favorable sealing property.The utility model sealing configuration compactness, spin balancing is good, long service life, processing cost is low, is conducive to promote the use of.
