[0017] specific implementation
[0018] image 3 The wedge-shaped shape 5 of the middle rectangular groove is viewed from A-A, and the cross-sectional shape of the rectangular groove 2 is a triangle; figure 1 It can be seen that the cross-sectional shape of the rectangular groove 2 is a rectangle when viewed from the front, and the wedge shape of the rectangular groove 2 is the wedge shape in common engineering applications. Therefore, the floating sealing ring 3 is evenly arranged with rectangular grooves 2 in the circumferential direction, the rectangular grooves 2 are rectangular, and the groove depth gradually decreases from the outer diameter to the inner diameter of the floating sealing ring 3 .
[0019] Figure 4 It is the installation diagram of the sealing ring in the wet clutch. with a certain pressure P The oil is supplied to the wet clutch along the oil inlet passage 7 through the oil inlet bush 6, and the oil inlet bush 6 does not rotate; the oil distributi...

The invention discloses a floating sealing ring with double effects of static pressure and dynamic pressure, solving the problem that a sealing ring is severely worn under a high-speed high-pressure working condition. The floating sealing ring is characterized in that throttle holes which are uniformly distributed in the periphery direction are formed on the end face of the sealing ring, a static pressure effect is formed under the action of high-pressure oil, oil film of certain rigidity is formed at the sealed end face, and an adequate opening force is realized; and meanwhile a plurality of rectangular grooves which are unequal in groove depths in the radial direction are arranged uniformly in the periphery direction, so that a dynamic pressure effect is formed during the work process of the sealing ring. With the adoption of the floating sealing ring, the wearing degree of the sealing ring can be reduced effectively, and meanwhile the lubrication performance of the sealing ring is improved, the working stability of the sealing ring is enhanced, the service life is prolonged, thus the floating sealing ring is applicable to the technical field of dynamic fluid sealing, and especially applicable to being used in a high-speed high-pressure wet type clutch.
Description
technical field [0001] The invention belongs to the technical field of fluid sealing, and is a fluid dynamic sealing part, more specifically a floating sealing ring applied in a wet clutch. Background technique [0002] Floating seal ring is a type of fluid dynamic seal, which plays a key role in preventing leakage and maintaining the normal operation of equipment. At the same time, it helps to eliminate or reduce environmental pollution, prevent or reduce material and energy consumption, and improve equipment efficiency. , The purpose of resource conservation. The vehicle wet clutch uses a floating sealing ring as a fluid sealing device to realize the establishment of its joint oil pressure. The sealing performance affects the power and stability of the transmission device, and is an important indicator for evaluating the overall transmission performance. [0003] The expansion of the industrial field puts forward stricter requirements on the sealing performance of mechani...
