Abstract
The invention relates to a shaft sealing device which comprises a sealing ring seat, wherein the sealing ring seat is sleeved outside a shaft. An annular cavity is formed between the sealing ring seat and the shaft, a sealing ring is sleeved on the shaft and is arranged in the cavity, a material sealing flange is arranged on one side of the sealing ring seat and is sleeved outside the shaft, an annular boss is arranged on the side of the material sealing flange close to the sealing ring seat and is matched with the cavity, the material sealing flange is connected with the sealing ring seat through a bolt, and a limit ring is sleeved on the bolt and is arranged on a screw on outer side of the material sealing flange through a nut. The shaft sealing device disclosed by the invention can effectively judge the fixing position of the bolt so that the bolt can not be screwed too tightly or loosely.
Description
Technical field
The present invention relates to technical field of sealing technology, be meant a kind of shaft sealer especially.
Background technique
On the input of seal container, output shaft, for the seepage that prevents material all is provided with shaft sealer usually.The structure of present employed shaft sealer comprises the seal ring seat that is set in the axle outside; Form the cavity of a ring-type between seal ring seat and the axle, be arranged with seal ring in the cavity, a side of seal ring seat is provided with envelope material flange; It is outside that envelope material flange is set in axle; Sidepiece near the envelope material flange of seal ring seat is provided with annular boss, and annular boss matches with cavity, and envelope material flange is connected with seal ring seat through screw.Above-mentioned shaft sealer when mounted; At first the seal ring seat suit is arranged on the outside of axle; The outside and the seal ring that then ring set are arranged on axle are arranged in the cavity, will seals a outside that material flange suit is arranged on spool and the front end of annular boss at last and be arranged in cavity, then through tightening screw; Make of the direction motion of envelope material flange to seal ring seat; Even annular boss is to the motion of the direction of seal ring, thus through annular boss with the seal ring compacting in cavity, reach the purpose of sealing.The shortcoming of above-mentioned shaft sealer is: when tightening screw; Owing to can't see the compaction of seal ring intuitively; Often can only rule of thumb judge the fixed position of screw; Screw occurs and twist too tightly or the situation of stubborn De Taisong, when screw is twisted too tightly, seal ring is sustained damage, when screw is twisted De Taisong, can influence sealing effect.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of and can judge the shaft sealer of the fixed position of screw effectively, thereby make screw can not twist to such an extent that too tightly also can not twist De Taisong.
For addressing the above problem, the technological scheme that the present invention adopts is: shaft sealer comprises being set in the outside seal ring seat of axle; Form the cavity of a ring-type between seal ring seat and the axle, be arranged with seal ring on the axle, seal ring is arranged in cavity; One side of seal ring seat is provided with envelope material flange, and it is outside that envelope material flange is set in axle, is provided with annular boss near the sidepiece of the envelope material flange of seal ring seat; Annular boss matches with cavity; Envelope material flange is connected with seal ring seat through screw, is arranged with stop collar on the described screw, and stop collar is arranged on the screw in the envelope material flange outside through nut.
Described stop collar set inside has spring, and spring housing is located on the screw.
Described envelope material flange is connected with seal ring seat through eight screws, and eight screws are along the annular setting.
The invention has the beneficial effects as follows: above-mentioned shaft sealer; Carry out spacing through stop collar to screw; Thereby can judge the fixed position of screw effectively, thereby make screw can not twist to such an extent that too tightly can not twist De Taisong yet, thereby seal ring can not sustain damage, can not influence sealing effect yet.
Description of drawings
Fig. 1 is the sectional structure schematic representation of shaft sealer of the present invention;
Fig. 2 is the sectional structure schematic representation of A-A direction among Fig. 1;
Among the figure: 1, axle, 2, seal ring seat, 3, cavity, 4, seal ring, 5, envelope material flange, 51, annular boss, 6, screw, 7, stop collar, 8, spring, 9, nut.
Embodiment
Through specific embodiment shaft sealer of the present invention is done further to describe in detail below.
As shown in Figure 1, shaft sealer comprises the seal ring seat 2 that is set in axle 1 outside; Form the cavity 3 of a ring-type between seal ring seat 2 and the axle 1, be arranged with seal ring 4 on the axle 1, seal ring 4 is arranged in cavity 3; One side of seal ring seat 2 is provided with envelope material flange 5, and envelope material flange 5 is set in axle 1 outside, is provided with annular boss 51 near the sidepiece of the envelope material flange 5 of seal ring seat 2; Annular boss 51 matches with cavity 3, and is as shown in Figure 2, and envelope material flange 5 is connected with seal ring seat 2 through eight screws 6; Eight screws 6 are provided with along annular, are arranged with stop collar 7 respectively on each screw 6, and stop collar 7 is arranged on the screw 6 in envelope material flange 5 outsides through nut 9; Described stop collar 7 set inside have spring 8, and spring 8 is set on the screw 6.
Above-mentioned shaft sealer when mounted; At first seal ring seat 2 suits are arranged on the outside of axle 1; Then seal ring 4 suits are arranged on axle 1 outside and seal ring 4 and are arranged in the cavity 3, will seal at last that material flange 5 suits are arranged on an outside of spool 1 and the front end of annular boss 51 is arranged in cavity 3, then through tightening screw 6; Make of the direction motion of envelope material flange 5 to seal ring seat 2; Even annular boss 51 is to the motion of the direction of seal ring 4, thus through annular boss 51 with seal ring 4 compactings in cavity 3, reach the purpose of sealing.When tightening screw 6, carry out through 7 pairs of screws of stop collar 6 spacing, thereby can judge the fixed position of screw 6 effectively, thereby make screw 6 can not twist to such an extent that too tightly also can not twist De Taisong, thereby seal ring 4 can not sustain damage, can not influence sealing effect yet.In addition, along with the growth of service time, wearing and tearing can appear in seal ring 4, and make seal ring 4 loosening in cavity 3 inner appearance, and this moment, envelope material flange 5 can further carry out compacting to seal ring 4 under the elastic force effect of spring 8, thus the assurance sealing effect.
The above embodiments are the principle and the effect thereof of illustrative the invention only, and the embodiment of part utilization, but not is used to limit the present invention; Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the invention design, can also make some distortion and improvement, these all belong to protection scope of the present invention.
