Description

Technical Field

[0001] The utility model relates to the technical field of mechanical transmission, in particular to a sealing element used for an inclined surface. Background Art

[0002] The skeleton oil seal is a typical representative of oil seals. Generally speaking, the oil seal refers to the skeleton oil seal. The function of the oil seal is generally to separate the parts of the transmission components that need to be lubricated from the external environment to prevent the lubricating oil from leaking. The skeleton is like the steel bar in the concrete component, which plays a reinforcing role and enables the oil seal to maintain its shape and tension. According to the structural form, it can be divided into single-lip skeleton oil seal and double-lip skeleton oil seal. The auxiliary lip of the double-lip skeleton oil seal plays a dust-proof role to prevent external dust, impurities, etc. from entering the machine. According to the skeleton type, it can be divided into inner skeleton oil seal, exposed skeleton oil seal and assembled oil seal. According to the working conditions, it can be divided into rotating skeleton oil seal and reciprocating skeleton oil seal. It is used in gasoline engine crankshafts, diesel engine crankshafts, gearboxes, differentials, shock absorbers, engines, axles and other parts. Because there is an oil film controlled by the oil seal edge between the oil seal and the shaft, this oil film has fluid lubrication characteristics. Under the action of the surface tension of the liquid, the stiffness of the oil film just forms a crescent surface at the contact end of the oil film and the air, preventing the leakage of the working medium, thereby realizing the sealing of the rotating shaft. Generally, lubricating oil is used to lubricate bearings and other parts. In order to prevent leakage of lubricating oil, an oil seal structure needs to be provided near the end of the rotating shaft.

[0003] At the upper end of the input shaft of the steering gear housing, a sliding bearing is usually arranged to support the shaft body. In addition, a skeleton oil seal is arranged to seal. The two are distributed along the axial direction. However, when sealing at some inclined positions, the oil will be affected by gravity and converge downward. The density parts lack elevation and folding angles. If too much oil is gathered, it will push the seal and cause leakage. Utility Model Content

[0004] The utility model aims to provide a sealing element for an inclined surface, which can facilitate the installation of the seal and prevent the side leakage caused by the oil convergence and squeezing, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sealing member for an inclined surface, comprising a mounting ring, a fixing block, an outer sealing plate, a connecting ring and an inner sealing plate, wherein the fixing block is fixedly mounted on the mounting ring, the outer sealing plate is fixedly mounted on the bottom of the fixing block, the connecting ring is fixedly mounted on the inner wall of the fixing block, and the inner sealing plate is fixedly mounted on the bottom of the connecting ring.

[0006] Furthermore, the inner wall of the mounting ring is open, and the cross section of the mounting ring is C-shaped.

[0007] Furthermore, the outer sealing plate is bent, and the angle between the outer sealing plate and the fixing block is 45 degrees.

[0008] Furthermore, the inner wall of the connecting ring is convexly arranged in a triangular shape.

[0009] In summary, due to the adoption of the above technology, the beneficial effects of the utility model are:
