Abstract

Be used for shaft sealing, assembly parts especially for the shaft sealing of the stern tube of ship, by the first fixing supporting ring of a shell, second supporting ring that shell is fixing and the elastic rubber sealing ring of packing between two supporting rings are formed, seal ring is made up of with an intermediate portion (thin slice) that is connected and supports the universal joint of sealing lip with clamping part a clamping part, wherein, first supporting ring has a cavity that is suitable for the clamping part of seal ring, the clamping part of seal ring can insert wherein, second supporting ring has a clamping boss that axially protrudes, and clamps above-mentioned clamping part with it.

Description

Be used for shaft sealing, especially for the assembly parts of the shaft sealing of the stern tube of ship
The present invention relates to a kind of shaft sealing that is used for, especially for the assembly parts of the shaft sealing of the stern tube of ship, it has the feature that the preamble of claim 1 provides.
In such assembly parts (DE-PS2609414), when the assembled group component, require seal ring is packed in the cavity that is made of a flange and circular groove with its back side.Because in this known assembly parts, the circular groove of first supporting ring extends to the intermediate portion (thin slice) of the universal joint of seal ring from flange, so at the near zone of axle an annular bump is set, the whole back side of seal ring is held tightly by pincer.
Therefore, particularly when the diameter of axle is big, may produce following difficulty, promptly seal ring tilt easily, thereby its back side can not be adjacent to the inwall of cavity fully when putting into.Sometimes, even if removing to clamp seal ring by the clamping boss of second supporting ring, this deficiency can not be eliminated, so the inclination of sealing the margin will cause pumping action at work and produce leakage.Because the seal ring axial thickness is less, the then necessary bending resistance in the back of seal ring, and the structure of this bending resistance must be revolted the engagement that hugs, so above-mentioned difficulties has strengthened.And then, because the unrestricted motion of holding the intermediate portion that has hindered the sealing lip universal joint tightly of described seal ring, so, because seal lip portion lacks back elasticity, the inclination meeting of described seal ring further aggravates when assembling, can see that the back elasticity of deficiency can cause leaking equally during the axle swing.Task of the present invention is to overcome these unfavorable factors, provide a kind of assembly parts, in the installation of this assembly seals circle, the engagement of the cavity of the seal ring and first supporting ring, clamping part is adjacent to the internal surface of cavity fully, and gives the big as far as possible degrees of freedom of lip part.
Because this task is finished according to the characteristic of claim 1, so the measure of Miao Shuing is applied on the assembly parts that is defined by preamble there.
Though said measure is used for shaft sealing in principle, but exceeded existing shaft sealing scope more or less, measure is a) open by Fig. 4 of DE-OS 2459732, measure b) and c) disclose by US-PS 4526385, measure d) open by Fig. 2 of US-PS3871666, yet these can not negate the present invention, because task proposed by the invention is to pass through a) to d) all measure and finished satisfactorily, and whether one or another be known in the combined feature, or whether the rudimentary combination of these features is known then unimportant.
By the following result of the combination results of four structure characteristics:
Because the conical expansion position has the common chamfering littler than cavity diameter, so, seal ring does not have resistance in a flash to the beginning that the cavity of first supporting ring pushes, and when further inserting the ring garden post part of cavity, the conical expansion position of seal ring is owing to the groove that is arranged on the clamping part back side rebounds, like this, expending less power can move forward, last, the chamfer site engagement of the conical expansion position and first supporting ring, seal ring is fixed on this unique position, can not tilt.Because the intermediate portion of seal ring universal joint (thin slice) is away from the internal ring wall of first supporting ring in whole insertion process, so therefore seal ring can not produce any inclination.
The embodiment who provides by accompanying drawing further explains the present invention below.
Fig. 1 is the assembly parts before the assembling;
Fig. 2 has been installed in an assembly parts in the shaft sealer, and shaft sealing has the seal arrangement of three axial arranged adjacent.
Among Fig. 1, for shape and the form that clearly illustrates that each ring, three rings of assembly parts, promptly above-mentioned first supporting ring 1, second supporting ring 2 and seal ring 6, space certain distance.In working order, seal ring 6 is packed between two supporting rings, and supporting ring 1 interconnects with 2 and is connected with the tailing axle propeller boss, and its shell is fixed.
In present this situation, first supporting ring is the medium (seawater) that will seal dorsad, in its side a toroidal cavity 3 is arranged towards seal ring, cavity 3 is that ring is columniform in its zone towards seal ring 6, but have annular chamfer 4,4 to cavity bottom expansion '.
In addition, in this embodiment, tilt to the inside at the ring wall 5 of the cavity 3 of axle side, inclined-plane 5 ' angle greater than the bevel angle 8 of the intermediate portion 8 of universal joint ', so this intermediate portion extends on the inclined-plane 5 ' free contact-type ground of installment state along ring wall 5.
Seal ring 6 usefulness elastic rubber materials are made, and it forms the intermediate portion 8 of sealing lip 7 promptly above-mentioned, universal joint and clamping part 9 by three parts.Sealing lip 7 is provided with an edge of a knife in common mode, and knife-edge support is on axle that will seal or axle sleeve.The intermediate portion of universal joint couples together sealing lip 7 and clamping part 9, and allows sealing lip 7 to move in any direction with respect to clamping part.The cavity 3 of the clamping part and first supporting ring 1 adapts, in zone be towards supporting ring 1 ring columniform, and have conical expansion position 10,10 '.
In this zone of in the end mentioning, seal ring 6 set in advance groove 11,11 ', groove 11,11 ' size be to determine like this, be that clamping part 9 is in the ring cylindrical region of cavity 3 when mobile, conical expansion position 10,10 ' resiliently deformable needn't expend too big power in the incipient stage of insertion process so.In order to insert easily, also have a common chamfering 12 on the conical expansion position.
When insertion process finishes soon, the conical expansion position 10,10 of seal ring 6 ' with chamfer site 4, the 4 ' engagement of supporting ring 1, and when guaranteeing that insertion process finishes, clamping part 9 comes to the bottom of cavity 3.
Second supporting ring 2 has a columniform clamping boss 13 of ring that axially protrudes, and in working order, clamps boss and is pressed on the clamping part 9 with certain pressure by its front surface towards seal ring 6, and like this, seal ring just is sandwiched between two supporting rings.
The assembly parts that in Fig. 2, has drawn and installed, here, seal arrangement has three axial adjacent lip seal that are bearing on the axle, wherein two lip seal 6,6 ' towards the medium that will seal (seawater), " direction is opposite in another lip seal 6.In this common seal arrangement, supporting ring 1 not only plays the first supporting ring effect of seal ring 6, and play seal ring 6 " the second supporting ring effect; supporting ring 2 not only plays the second supporting ring effect of seal ring 6; and play seal ring 6 ' the first supporting ring effect, and for seal ring 6 ' second independent supporting ring 2 of needs ', " need first an independent supporting ring 1 " for seal ring 6; at supporting ring 1 " in, annular chamfer 4,4 " is arranged on the ring cylindrical region.
