Description

Technical Field

[0001] This invention relates to the technical field of sealing oil stops, and more particularly to a pneumatically floating sealing oil stop. Background Technology

[0002] Oil baffles are made of metal and are generally used in large, high-speed rotating machinery, such as steam turbines. They use a relatively high-speed rotating oil film to seal the oil. Oil baffles are traditional comb-type seals with a simple structure. However, oil baffles have always had problems such as oil leakage, oil splashing, and even shaft wear and water / vapor ingress. These problems can easily cause fires and water ingress accidents, seriously threatening the safety of the unit.

[0003] Furthermore, the existing oil level gauge is relatively difficult to install, usually requiring the assistance of other parts, which is quite laborious. In addition, the existing oil level gauge's sealing structure is not adjustable, and it cannot be used on parts with slight dimensional deviations. Summary of the Invention

[0031] Example 1

[0032] Reference Figure 1 A pneumatic floating sealing oil baffle includes an oil baffle mechanism 100 and a locking mechanism 200. The oil baffle mechanism 100 is mounted on a stationary ring on the bearing bush to prevent lubricating oil leakage and to prevent foreign objects from entering the bearing and contaminating the lubricating oil.

[0033] Specifically, the oil baffle mechanism 100 includes an annular block 101, which is matched and set according to the size of the bearing to be installed. An outer fitting pad 102 is installed on the outer wall of the annular block 101. The outer fitting pad 102 is in contact with the outer bearing shell to prevent the lubricating oil from leaking out. An inner fitting pad 103 is installed on one side of the inner wall of the annular block 101. The inner fitting pad 103 is in contact with the inner side of the bearing shell to prevent the lubricating oil from leaking out.

[0034] Operating procedure: When using the oil stop, install the annular block 101 between the bearing bushes, so that the outer ring of the annular block 101 is slightly in contact with the inner side of the outer bearing bush, and the inner ring of the annular block 101 is slightly in contact with the outer side of the inner bearing bush. At this time, the bearing bushes can be sealed by the oil stop.

[0035] Example 2

[0036] Reference Figures 2-6 This embodiment differs from the first embodiment in that the locking mechanism 200 includes a rotating component 201 mounted on the annular block 101. The rotating component 201 is installed inside the annular block 101 and extends beyond the outer wall of the annular block 101, used to rotate and actuate the locking component 203, thereby causing the locking component 203 to quickly lock the annular block 101 onto the applied component. A transmission component 202 is mounted on the rotating component 201, used to transmit the rotation of the rotating component 201. The signal is transmitted to the locking assembly 203, which is then activated. When the locking assembly 203 is activated, it protrudes from the outer ring of the annular block 101, thus locking the annular block 101 in place. In use, the annular block 101 is placed on the component, and then the rotating assembly 201 is rotated. The rotating assembly 201 drives the transmission assembly 202, which in turn activates the locking assembly 203, thereby quickly installing the annular block 101.

[0037] Specifically, the rotating assembly 201 includes a rotating block 201a disposed on the annular block 101, the rotating block 201a being mounted on the outer side of the annular block 101 and capable of being rotated by a tool; a rotating shaft 201b disposed on the rotating block 201a, the rotating shaft 201b being mounted on one end of the rotating block 201a, and the rotating shaft 201b being rotated when the rotating block 201a rotates; and an embedded block 201c disposed on the rotating shaft 201b, the embedded block 201c being fixedly mounted on the rotating shaft 201a. The rotating shaft 201b is mounted on the rotating shaft 201b, and the embedded block 201c is embedded inside the large gear 202a, so that when the rotating shaft 201b rotates, it can drive the large gear 202a to rotate. The limiting member 201d is provided on the rotating block 201a, which is used to make the rotating block 201a protrude outside the annular block 101. When locking is required, the rotating block 201a rotates to drive the rotating shaft 201b to rotate, the rotating shaft 201b rotates to drive the embedded block 201c to rotate, and the embedded block 201c rotates to drive the large gear 202a to rotate.

[0038] Furthermore, the limiting member 201d includes a receiving groove 201d-1 formed on the rotating block 201a. A small spring 201d-2 is installed on the inner wall of the receiving groove 201d-1. The small spring 201d-2 causes the limiting block 201d-3 to protrude from the rotating block 201a, so that the rotating block 201a will not be embedded in the annular block 101. The limiting block 201d-3 set on the small spring 201d-2 causes the limiting block 201d-3 to protrude from the rotating block 201a, so that when the rotating block 201a is rotated with force, the rotating block 201a will not be pressed into the annular block 101.

[0039] Furthermore, the transmission assembly 202 includes a large gear 202a mounted on a rotating shaft 201b, which is driven by the rotating shaft 201b; a connecting rod 202b mounted on the annular block 101, which fixes a small gear 202c and an elliptical block 203b together; and the small gear 202c can drive the connecting rod 202b to rotate. The small gear 202c mounted on the connecting rod 202b meshes with the large gear 202a. The rotation of the large gear 202a drives the small gear 202c to rotate, which in turn drives the connecting rod 202b to rotate, and the rotation of the connecting rod 202b drives the elliptical block 203b to rotate.

[0040] Furthermore, the locking assembly 203 includes an arc-shaped block 203a disposed on the annular block 101, the arc-shaped block 203a being movably mounted inside the annular block 101 via a fixed shaft; an elliptical block 203b disposed on the connecting rod 202b, the elliptical block 203b being located on one side of the arc-shaped block 203a; and a mating part 203c disposed on the annular block 101, the mating part 203c being used to fix the rotated large gear 202a. The rotation of the connecting rod 202b drives the elliptical block 203b to rotate, and the rotation of the elliptical block 203b gradually presses against the inner side of the arc-shaped block 203a, causing the arc-shaped block 203a to gradually be pressed out of the annular block 101, so that the protruding arc-shaped block 203a contacts the mounting surface, thereby locking the annular block 101. When the fixing is secure, the mating part 203c can be used to lock the large gear 202a, so that the locking is maintained.

[0041] Furthermore, the mating component 203c includes a telescopic rod 203c-1 disposed on the annular block 101. The telescopic rod 203c-1 is installed inside the annular block 101. The telescopic rod 203c-1 prevents the locking ring 203c-2 from being driven by the rotating shaft 201b. The locking ring 203c-2 is installed at one end of the telescopic rod 203c-1 and is connected to the rotating shaft 201b via a bearing. A locking groove 203c-3 is disposed on the large gear 202a. The locking groove 203c-3 is formed on the end face of the large gear 202a. The locking ring 203c-2 is disposed on the locking groove 203c-2. Locking block 203c-4 is located on one side of locking groove 203c-3. When the annular block 101 is locked, the limiting block 201d-3 can be pressed to retract into the receiving groove 201d-1. Then, the rotating block 201a is pressed to make the locking ring 203c-2 and locking block 203c-4 on the rotating shaft 201b embed into the locking groove 203c-3. At this time, the large gear 202a can be locked. At this time, the embedding block 201c is separated from the large gear 202a, so that the rotation of the rotating shaft 201b does not affect the large gear 202a.

[0042] The rest of the structure is the same as in Example 1.

[0043] Operation process: When locking is required, the rotating block 201a rotates, driving the rotating shaft 201b to rotate. The rotating shaft 201b rotates, driving the embedded block 201c to rotate. The embedded block 201c rotates, driving the large gear 202a to rotate. The small gear 202c meshes with the large gear 202a. The large gear 202a rotates, driving the small gear 202c to rotate. The small gear 202c rotates, driving the connecting rod 202b to rotate. The connecting rod 202b rotates, driving the elliptical block 203b to rotate. The rotation of the elliptical block 203b gradually squeezes the inner side of the arc-shaped block 203a, causing the arc-shaped block 203a to gradually squeeze out of the outer side of the annular block 101, so that the protruding arc-shaped block 203a contacts the mounting surface, thereby locking the annular block 101. When the locking installation is performed and the device is securely fixed, the large gear 202a can be locked with the mating part 203c to maintain the lock. When the annular block 101 is locked, the limiting block 201d-3 can be pressed to retract the limiting block 201d-3 into the receiving groove 201d-1. Then, the rotating block 201a is pressed to make the locking ring 203c-2 and the locking block 203c-4 on the rotating shaft 201b embed into the locking groove 203c-3. At this time, the large gear 202a can be locked. At this time, the embedding block 201c is separated from the large gear 202a, so that the rotation of the rotating shaft 201b does not affect the large gear 202a. This structure allows for quick installation of the oil stop and secure locking without loosening.

[0044] Example 3

[0045] Reference Figures 6-8 This embodiment differs from the above embodiments in that it further includes an adjustment mechanism 300, comprising an airbag 301 disposed on the annular block 101, the airbag 301 being located between the outer bonding pad 102 and the inner bonding pad 103. The airbag 301 inflates to bond the outer bonding pad 102 and the inner bonding pad 103 to the mounting surface, thereby completing the seal. A column 302 is disposed on the airbag 301 and fixed inside the annular block 101. An adjustment component 303 is disposed on the column 302. The adjustment component 303 can inject gas from the column 302 into the airbag 301 or draw gas from the airbag 301 into the column 302, thereby changing the bonding force between the outer bonding pad 102 and the inner bonding pad 103, and adjusting the seal according to different needs.

[0046] Specifically, the adjustment component 303 includes a connector 303a disposed on the column 302, the connector 303a connecting the extruder 303b to the rotating shaft 201b, the extruder 303b disposed on the connector 303a, the extruder 303b can be rotated to de-inflate or inflate the airbag 301.

[0047] Furthermore, the connector 303a includes a hexagonal block 303a-1 mounted on the rotating shaft 201b, the hexagonal block 303a-1 being installed at the end of the rotating shaft 201b, a connecting shaft 303a-2 mounted on the column 302, the connecting shaft 303a-2 being connected to the inside of the column 302 via a bearing, and a hexagonal groove 303a-3 mounted on the connecting shaft 303a-2, the hexagonal groove 303a-3 being formed at one end of the connecting shaft 303a-2 and located on one side of the hexagonal block 303a-1. When the large gear 202a is locked, its rotating shaft 201b is pressed and displaced, and the displaced rotating shaft 201b causes the hexagonal block 303a-1 to embed into the hexagonal groove 303a-3. At this time, when the rotating block 201a rotates, it can drive the connecting shaft 303a-2 to rotate.

[0048] Furthermore, the extrusion component 303b includes a screw 303b-1 mounted on the connecting shaft 303a-2, the screw 303b-1 being installed at one end of the connecting shaft 303a-2; an internally threaded rod 303b-2 mounted on the screw 303b-1, the internally threaded rod 303b-2 being threadedly engaged with the screw 303b-1; a piston block 303b-3 mounted on the internally threaded rod 303b-2, the piston block 303b-3 being in contact with the inner wall of the cylinder 302; and a limiting rod 303b-4 mounted on the piston block 303b-3, limiting the movement of the piston. The plug 303b-3 does not rotate. When the connecting shaft 303a-2 rotates, the rotation of the connecting shaft 303a-2 drives the screw 303b-1 to rotate. The rotation of the screw 303b-1 drives the internal thread rod 303b-2 to move. The movement of the internal thread rod 303b-2 drives the piston to move. The movement of the piston causes the airbag 301 to inflate or deflate, thereby changing the adhesion force between the outer bonding pad 102 and the inner bonding pad 103. Thus, the degree of bulging of the outer bonding pad 102 and the inner bonding pad 103 can be adjusted according to the specific mounting surface, thereby improving the sealing effect.

[0049] The rest of the structure is the same as in Example 2.

[0050] Operation process: Hexagonal slot 303a-3 is formed at one end of connecting shaft 303a-2 and located on one side of hexagonal block 303a-1. When locking the large gear 202a, its rotating shaft 201b is pressed and displaced. The displaced rotating shaft 201b causes hexagonal block 303a-1 to embed into hexagonal slot 303a-3. At this time, when rotating block 201a rotates, it can drive connecting shaft 303a-2 to rotate. When connecting shaft 303a-2 rotates, the connection... The rotation of shaft 303a-2 drives the screw 303b-1 to rotate, the rotation of screw 303b-1 drives the internal thread rod 303b-2 to move, the movement of internal thread rod 303b-2 drives the piston to move, the movement of piston causes airbag 301 to inflate or deflate, thereby changing the adhesion force between outer bonding pad 102 and inner bonding pad 103. Thus, the degree of bulging of outer bonding pad 102 and inner bonding pad 103 can be adjusted according to the specific mounting surface, thereby improving the sealing effect.
