According to the utility model, the bearing mounting end and the graphite mounting end of the guider are sealed during the tightness detection of the guider, so that the phenomenon that lubricating oil enters the air cavity from the oil cavity through a peripheral gap and the sealing performance of the guider is unqualified due to the fact that the air cavity is communicated with the oil cavity is avoided.
Description
Technical Field
The utility model belongs to the technical field of tool parts, and particularly relates to a sealing device.
Background
If the relevant parts of the guider have damages such as welding failure, cracks and the like, phenomena such as lubricating oil leakage, sintering and the like are easy to occur, and when the gas turbine starter is used under the working condition for a long time, damages such as bearing failure and shaft explosion of a gas generator shaft can be caused, and the airplane, the engine or personnel can be seriously damaged.
When the gas turbine starter is repaired, whether the relevant part of the guider has damages such as welding failure, cracks and the like can be identified through the detection of sealing performance. However, the structure of the guider is complex, and lubricating oil is easy to permeate into a peripheral gap through a bearing mounting end or a graphite mounting end during the tightness detection, so that the phenomenon that an air cavity is communicated with an oil cavity occurs, and the false phenomenon that the tightness of the guider is unqualified is caused.
SUMMERY OF THE UTILITY MODEL
The utility model provides a sealing device, which is used for sealing a bearing mounting end and a graphite mounting end of a guider during the detection of the sealing property of the guider, so that lubricating oil is prevented from entering an air cavity from an oil cavity through a peripheral gap, and the false phenomenon that the sealing property of the guider is unqualified due to the fact that the air cavity is communicated with the oil cavity is caused.
The technical scheme of the utility model is as follows: a sealing device comprises a sealing seat, a connector and a sealing plate, wherein the sealing seat and the connector are connected through a ventilation plug; the sealing seat is connected with the bearing mounting end of the guider, and a sealing seat sealing gasket is arranged between the sealing seat and the bearing mounting end of the guider; the graphite mounting end of the guider is fixed on the connector, a connector sealing gasket is arranged between the graphite mounting end of the guider and the connector, and a sealing ring is arranged on the connector; one end of the ventilating plug is sealed by a ventilating plug sealing gasket, and the other end of the ventilating plug is provided with a hexagon bolt; the sealing plate is fixed on the connector, and a sealing plate sealing gasket is arranged between the sealing plate and the connector. The sealing plate is fixed through a hexagon bolt.
The utility model has the beneficial effects that: when the guider is sealed and detected, the air in the oil cavity of the guider is removed through the air discharging function of the ventilating plug, so that the oil cavity is full of oil, and then the air cavity and the oil cavity can be effectively isolated by matching the sealing plate, the sealing seat, the connector, the sealing gasket and the sealing ring, so that a multi-sealing structure is formed, the oil is prevented from entering the air cavity through a peripheral gap, and the working efficiency and the tightness detection accuracy are improved.

FIG. 1 is a schematic view of a disassembled structure of the sealing device of the present invention;
the reference numbers in the drawings are respectively: 1-hexagon bolt, 2-ventilation plug, 3-ventilation plug gasket, 4-sealing seat, 5-sealing seat gasket, 6-connector gasket, 7-sealing ring, 8-connector, 9-sealing plate gasket, 10-sealing plate and 11-guider.
Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and examples.
Examples
As shown in the figure, the sealing device comprises a sealing seat 4, a connector 8 and a sealing plate 10, wherein the sealing seat 4 and the connector 8 are connected through a ventilation plug 2; the sealing seat 4 is connected with the bearing mounting end of the guider, and a sealing seat gasket 5 is arranged between the sealing seat 4 and the bearing mounting end of the guider; the graphite mounting end of the guider is fixed on a connector 8, a connector sealing gasket 6 is arranged between the graphite mounting end and the connector, and a sealing ring 7 is arranged on the connector; one end of the ventilating plug 2 is sealed by a ventilating plug sealing gasket 3, and the other end of the ventilating plug is provided with a hexagon bolt 1; the sealing plate 10 is fixed on the connector 8, and a sealing plate gasket 9 is arranged between the two.
The sealing seat 4 is connected with the connector 8 through the ventilating plug 2, and forms a first sealing structure of the bearing mounting end and the graphite mounting end with the sealing seat sealing gasket 5 and the connector sealing gasket 6 respectively. The ventilating plug 2 is sealed by a ventilating plug sealing gasket 3, sealed and deflated by a hexagon bolt, and a sealing ring 7 is installed on the connector 8 to form a second sealing structure at the graphite installation end. The sealing plate 10 is fastened through the hexagon bolt 1 and the connector 8, and forms a third sealing structure of the graphite mounting end with the sealing plate sealing gasket 9.
In the above embodiment, the graphite mounting end passes through the three sealing structures, and the bearing mounting end passes through the sealing structure and the air release structure, so that the isolation of the air cavity and the oil cavity can be effectively realized, and the misjudgment condition of the detection result caused by the fact that oil enters the air cavity through the peripheral gap during the detection of the sealing performance is prevented.
