Abstract
The invention discloses a test tool for preventing muddy water invasion and oil leakage of an oil seal, and relates to the technical field of sealing. This experimental frock includes experimental axle, experimental dish, has the muddy water tank of import and export, its characterized in that: the testing device is characterized in that a sealing medium box with an inlet and an outlet is arranged beside the muddy water box, the testing disc is arranged between the muddy water box and the sealing medium box, an oil seal is arranged between the testing shaft and the testing disc, and a motor shaft penetrates into the sealing medium box and is connected with the testing shaft. According to the invention, the sealing medium box is added on the basis of the original oil seal muddy water experiment tool, so that the muddy water invasion prevention of the oil seal can be verified, the outward leakage of the sealing medium (lubricating oil or lubricating grease) in the oil seal can also be verified, and the influence on the normal use of the product is avoided.
Description
Technical Field
The invention relates to the technical field of sealing, in particular to a test tool for preventing muddy water invasion and oil leakage of an oil seal.
Background
The oil seal is a mechanical element for sealing lubricating oil of a lubricating system, and separates a part needing lubricating from a power output part in a transmission part, so that the lubricating oil is prevented from leaking, and impurities such as external muddy water and dust are prevented from entering the lubricating system. The damage of external impurities such as muddy water and dust to the oil seal can be fatal, so that the adaptability of the oil seal to the muddy water or the dust is required to be considered at the beginning of the oil seal design, and therefore, the use of a test tool for preventing the oil seal from being invaded by muddy water and leaking oil is indispensable.
To the experimental frock of oil blanket prevention muddy water invasion and oil leakage, provided a technical scheme in patent No. 201220543346.2 oil blanket muddy water experiment frock, its concrete technical scheme is: the oil seal is fixed on the test shaft and the test disc, the muddy water tank is connected with the test disc, and during the rotation test of the test shaft, muddy water is filled in the muddy water tank, so that the test oil seal is guaranteed to be externally immersed in the muddy water. However, in the technical scheme, only the mud water is prevented from invading the inside of the oil seal, so that the problem that the sealing medium in the oil seal leaks outwards cannot be verified at the same time exists.
Disclosure of Invention
The invention aims to provide a test tool for preventing muddy water invasion and oil leakage of an oil seal, which can simultaneously verify the muddy water invasion prevention of the oil seal and the outward leakage of an internal sealing medium.
In order to solve the problems, the invention adopts the technical scheme that:
the device comprises a test shaft, a test disc and a muddy water tank with an inlet and an outlet; the method is characterized in that: the testing device is characterized in that a sealing medium box with an inlet and an outlet is arranged beside the muddy water box, the testing disc is arranged between the muddy water box and the sealing medium box, an oil seal is arranged between the testing shaft and the testing disc, and a motor shaft penetrates into the sealing medium box and is connected with the testing shaft.
In the above technical solution, a more specific technical solution may also be: the test disc is simultaneously connected with the sealing medium box and the muddy water box through bolts.
Furthermore, the connection positions between the test disc and the sealing medium box and between the test disc and the muddy water box are provided with additional sealing rings.
Further, the test shaft is connected with the motor shaft through a bolt.
Furthermore, the motor shaft sealing device also comprises a bearing cover, and the bearing cover is simultaneously connected with the motor shaft and the sealing medium box through bolts.
Furthermore, a sealing ring is arranged between the motor shaft and the bearing cover.
In the above technical solution, a more specific technical solution may also be:
due to the adoption of the technical scheme, compared with the prior art, the invention has the following beneficial effects:
according to the invention, the sealing medium box is added on the basis of the original oil seal muddy water experiment tool, so that the muddy water invasion prevention of the oil seal can be verified, the outward leakage of the sealing medium (lubricating oil or lubricating grease) in the oil seal can also be verified, and the influence on the normal use of the product is avoided.
