Description
Technical Field
The patent of the utility model relates to a novel seal structure of underwater robot belongs to the sealed field of underwater robot.
Background
As marine and seabed resources are continuously explored and developed, underwater robots are also widely applied to the field. Because the underwater robot moves underwater, a plurality of movable joints of the underwater robot need to be sealed, and the good sealing performance directly influences the operation of the underwater robot. The existing commonly used underwater sealing ring generally utilizes the elasticity of an annular spiral spring to press the sealing ring part on a shaft to achieve the sealing effect, but the sealing structure has the following defects in the field of underwater application that (1) the abrasion is fast and the service life is low; (2) the underwater sealing performance is poor, and the leakage (3) is easy to assemble and disassemble.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a simple structure, sealing performance are stable, the novel seal structure of robot under water of easy assembly and dismantlement for solving the not enough of above-mentioned technique.
In order to achieve the purpose, the novel underwater robot sealing structure comprises a machine base (1), an O-shaped sealing ring (2), a sealing base (3), a star-shaped sealing ring (4), a wear-resistant sealing ring (5) and a shaft (6). The O-shaped sealing ring (2) is arranged in an outer groove of the sealing seat (3), the star-shaped sealing ring (4) is clamped on the inner groove of the sealing seat (3) and pressed on the wear-resistant sealing ring (5), the wear-resistant sealing ring (5) is pressed on the shaft (6), and the sealing seat (3) and the machine base (1) are fixedly connected through screws.
The star-shaped sealing ring (4) is made of Polytetrafluoroethylene (PTFE) material, so that the elasticity is high; the wear-resistant sealing ring (5) is made of polytetrafluoroethylene materials with fillers, and the materials are wear-resistant and relatively small in elasticity.

Detailed Description
As shown in fig. 1 and 2, the novel underwater robot sealing structure comprises an underwater robot sealing structure, which comprises a base (1), an O-shaped sealing ring (2), a sealing seat (3), a star-shaped sealing ring (4), a wear-resistant sealing ring (5) and a shaft (6). The O-shaped sealing ring (2) is arranged in an outer groove of the sealing seat (3), the star-shaped sealing ring (4) is clamped on the inner groove of the sealing seat (3) and pressed on the wear-resistant sealing ring (5), the wear-resistant sealing ring (5) is pressed on the shaft (6), and the sealing seat (3) and the machine base (1) are fixedly connected through screws.
The O-shaped sealing ring (2), the star-shaped sealing ring (4) and the wear-resistant sealing ring (5) are assembled with the sealing seat (3) firstly and then assembled with the machine base (1) and the shaft (6), and the structure is easy to assemble and disassemble.
The sealing seat (3) is used for installing the star-shaped sealing ring (4) and the wear-resisting sealing ring (5), the depth of the two sides of the groove is different by h, the shallow height T exceeds the thickness of the star-shaped sealing ring (4) by about 2-5 mm (depending on the structure size), the groove for installing the sealing ring is generally required to be deep, and one side of the groove is relatively shallow, so that the sealing ring is easy to install.
The star-shaped sealing ring (4) has better elasticity, the thickness is compressed after the star-shaped sealing ring is assembled, and the wear-resistant sealing ring (5) is pressed on the shaft by using the rebound force of volume compression, so that the sealing effect between the base (1) and the shaft (6) is achieved.
Claims (3)
