A kind of axle sleeve can seal by compensation machine for the assembly of unit load tool, comprise drive sleeve, bellows, dynamic sealing assembly, stationary ring, gland, axle sleeve and bearing, wherein drive sleeve is connected by bellows with axle sleeve, described drive sleeve is connected with running shaft, between described axle sleeve and running shaft, leave gap, described axle sleeve and gland are dynamically connected by bearing rotary, are provided with dynamic sealing assembly and stationary ring between described gland and axle sleeve, described stationary ring is connected with gland, and described dynamic sealing assembly is connected with axle sleeve and locates by bearing.
Between described stationary ring and gland, between dynamic sealing assembly and axle sleeve and be equipped with 0 RunddichtringO between drive sleeve and running shaft.Described dynamic sealing assembly and stationary ring are determined relative position by bearing, and described bearing is deep groove ball bearing.The end of described bearing is by the pressing plate axial limiting being connected with gland.
Weld with drive sleeve and axle sleeve respectively at the two ends of described bellows.Described bellows is metal bellows.
Advantage of the present utility model and good effect are:
1. the utility model is applicable to the centrifugal pump that vibration is larger.
2. the utility model good sealing effect, long service life.
3. the utility model is changed simply, reduces workload and cost.
4. the Vibration Synchronization of the utility model mechanical seal and the pump housing, guarantees that friction pair does not produce relative displacement, and practical application effect is better.
5. the utility model combines mechanical seal, bearing and welded metal bellow, compact structure, and convenient disassembly, brings into play mechanical seal superior function to greatest extent, uses reliable and stablely, has solved the sealing problem of this type of pump.
The utility model by the moment of torsion transmission of axle sleeve with locate the two and separate solution, axle sleeve is divided into two-part, centre connects with welded metal bellow, bellows plays sealing, vibration damping and transmitting torque effect, location is completed by the bearing being arranged in gland, rationally solves the leakage problem that this type of pump causes due to vibration.
7. the utility model is arranged on mechanical seal on axle sleeve and gland, and axle sleeve and gland are located by bearing, and inner hole of shaft sleeve and pump shaft have larger gap, and while producing vibration, the two is not interfered.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1 is plain cushion, 2 is drive sleeve, and 3 is axle sleeve 0 shape seal ring, and 4 is bellows, and 5 is dynamic sealing assembly, 6 is stationary ring, and 7 is that stationary ring 0 shape seal ring 7,8 is gland 0 shape seal ring, and 9 is gland, and 10 is axle sleeve, 11 is bearing, and 12 is jump ring, and 13 is pressing plate, and 14 is Cock screw.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, the utility model comprises drive sleeve 2, bellows 4, dynamic sealing assembly 5, stationary ring 6, gland 9, axle sleeve 10 and bearing 11, wherein weld with drive sleeve 2 and axle sleeve 10 respectively at the two ends of bellows 4, described drive sleeve 2 is connected with running shaft, the endoporus of described axle sleeve 10 is greater than running shaft, do not contact with running shaft, between axle sleeve 10 and running shaft, leave gap.Described axle sleeve 10 is dynamically connected by bearing rotary with gland 9, and the end of described bearing is by pressing plate 13 axial limitings, and described pressing plate 13 is connected with gland 9 by Cock screw 14, and Cock screw 14 is interior hexagon concave-end locking screw.Between described gland 9 and axle sleeve 10, be provided with dynamic sealing assembly bonded to each other 5 and stationary ring 6, described stationary ring 6 is connected with gland 9, and described dynamic sealing assembly 5 is connected with axle sleeve 10 and locates by bearing 11, and described bearing 11 is deep groove ball bearing.Between described stationary ring 6 and gland 9, be provided with stationary ring 0 RunddichtringO 7, between dynamic sealing assembly 5 and axle sleeve 10, be provided with rotating ring 0 RunddichtringO, between drive sleeve 2 and running shaft, be equipped with axle sleeve 0 RunddichtringO 3.Described dynamic sealing assembly 5 is prior art, adopts spring type mechanical sealing.
Working principle of the present utility model is:
The utility model is the relative displacement dynamic and static friction pair being produced by reducing pump housing vibration, realizes mechanical seal steady running.The axle sleeve that plays transmitting torque and positioning action is divided into two bodies and adopts welding manner to pass through metal bellows 4 be connected, bellows 4 plays sealing, vibration damping and transmitting torque effect.Axle sleeve 10 is installed seal rotary assembly position endoporus and is strengthened, and does not contact with pump shaft, and this section of pump shaft is that axle sleeve 10 is connected location by bearing 11 with gland 9, and sealing installment work is highly also determined by bearing 11.Static friction pair is arranged on gland 9, and pump shaft and housing are because the displacement of generation of vibration is regulated by the metal bellows 4 welding.When pump operation, seal rotary assembly and stationary ring and pump housing synchronous shift, dynamic and static friction pair does not have relative displacement, thereby realizes sealing steady running.
The utility model erection sequence is: the sealing of collection dress is installed, and fastening gland and sleeve nut, get final product running device.When the utility model operation, pump shaft vibration is effectively absorbed by bellows 4, and hull vibration is synchronously passed to mechanical seal by bearing 11, although there is vibration, dynamic and static friction pair is synchronous, less to sealing normal influence on system operation.
