Abstract
An underwater moving sealing device comprises a rudder face (1), a rudder shaft (2), a cabin body (3), a bearing A (4), a bearing B (5), a bearing cover (6), a front moving sealing part (7) and a rear moving sealing part (8), wherein the front moving sealing part (7) comprises a friction ring (9) and a rubber ring (10); the front moving sealing part (7) and the rear moving sealing part (8) are totally same in structure; the contacting face between the cabin body (3) and the rudder shaft (2) is sealed by the front moving sealing part (7) and the rear moving sealing part (8). The underwater moving sealing device effectively solves the underwater moving sealing problem of small-sized devices, is compact in structure, small in size and easy to realize, and can be used for working under the conditions of external pressure of 30MPa and the circular velocity of 0.5-10m/s; meanwhile, the anti-abrasion and reliability at the condition of underwater navigation are effectively improved by the design of the two paths of sealing parts.
Description
Technical field
The utility model relates to a kind of seal arrangement, particularly a kind of dynamic seal apparatus under water.
Background technique
Water tightness is prerequisite and key, the especially motive sealing of underwater navigation device that the underwater units function realizes, need to be in guaranteeing the underwater navigation process on the basis of moving element Sealing ne-leakage, can also bear necessarily the destructive pressure on the degree of depth under water.
Dynamic seal apparatus is developed for the Large Underwater navigational equipment mostly under water at present, complex structure, and size is large, application difficult on the small-scale underwater vehicle device.And small-sized sealing part O type circle commonly used is while being applied to rotary dynamic seal, the frictional heat because rotatablely moving and producing, will make O type circle tighten up, and tightening force increases, and iterative cycles, just impel ageing of rubber and Fast Wearing, therefore is not suitable for motive sealing under water.
As national inventing patent ZL200610156882.6 dynamic seal apparatus, described seal arrangement mainly comprises pedestal, rotating shaft, a bearing in the form of a ring, is positioned at the seal ring group of pedestal, the seal ring group is comprised of inner seal ring and outer seal ring, be installed between axle and casing, be sheathed on axle, can be with the axle free floating while doing, seal wears is fast, easy to leak, navigate by water application difficult on device under water.
The model utility content
The purpose of this utility model is to provide a kind of dynamic seal apparatus under water, solve current dynamic seal apparatus application difficult on the small-scale underwater vehicle device, and small-sized sealing part O type circle commonly used is not suitable for the problem of rotary dynamic seal under water.
A kind of dynamic seal apparatus under water comprises: rudder face, rudderpost, cabin body, bearing A, and bearing B, bearing cap also comprise: front dynamic seal and rear dynamic seal, wherein, front dynamic seal, comprise: friction ring and rubber ring, the structure of rear dynamic seal and front dynamic seal are identical, rudder face and rudderpost screw are fixed, body top, cabin is useful on the step hole that rudderpost is installed, rudderpost coaxially is placed in the body step hole of cabin, bearing A and bearing B coaxial sleeve are at the rudderpost two ends, its middle (center) bearing A outer ring is near cabin body step hole wall, bearing B inner ring is close to the bearing cap lower surface, bearing cap is connected with rudderpost bottom screw, the rudderpost front end has front rectangular seal groove and rear rectangular seal groove, front dynamic seal is embedded in the front rectangular seal groove on rudderpost, rear dynamic seal is embedded in the rear rectangular seal groove of rudderpost, friction ring and rubber ring are respectively along the radially inside and outside distribution of rudderpost.
Rudder face directly contacts with water in the navigation process with the cabin external surface, and cabin body and rudderpost surface of contact are realized sealing by front dynamic seal and rear dynamic seal; The front rectangular seal groove of the relative rudderpost of rubber ring of front dynamic seal and rear dynamic seal and the size of rear rectangular seal groove are larger, guarantee to still have the decrement of 5%-6% after front dynamic seal and the assembling of rear dynamic seal, thereby realize the ne-leakage requirement.
This device has effectively solved midget plant motive sealing problem under water, and this compact structure, size be little, be easy to realize, and the working condition of rubber ring also improves greatly, can be used under the peripheral velocity of 0.5m/s ~ 10m/s and works; Twice dynamic seal design simultaneously effectively raises the reliability of wear resistance and underwater navigation; Before and after in rudderpost and cabin body, the step design, can bear and be not less than 30MPa pressure, can be used for small-sized deep water navigation device.
