Description

Technical Field

[0001] This utility model belongs to the field of sealing equipment, and specifically relates to an oil-separating sealing structure for a gearbox baffle. Background Technology

[0002] A transmission baffle is a functional component inside or outside the transmission, primarily used to separate different areas within the transmission, secure parts, or provide sealing. Currently, some transmission baffles have shortcomings in design and practical use. Due to structural design factors, they are difficult to effectively constrain the transmission fluid during operation, leading to fluid leakage from the joint between the baffle and the transmission housing. This is mainly due to poor sealing performance at the joint surface, failing to adequately consider the effects of fluid pressure and vehicle vibration during operation. A conventional solution is to apply sealant to the joint surface, which can alleviate leakage to some extent. However, the sealant is prone to aging and failure due to high temperatures and fluid immersion, requiring periodic reapplication. Furthermore, removing residual sealant during baffle removal is difficult and may damage the baffle or transmission housing surface, affecting resealing effectiveness. Therefore, a new structure is needed to address these technical problems. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1 to 3 As the first embodiment of this utility model: an oil-separated sealing structure for a gearbox baffle, comprising: a baffle assembly and a sealing assembly, the baffle assembly comprising a baffle body 100, the surface of the baffle body 100 having an oil hole 101 for oil passage, the front side surface of the baffle body 100 integrally forming an annular part, the sealing assembly comprising a sealing cover 200 for sealing, the inner side surface of the sealing cover 200 being fitted with a sealing element for sealing the oil hole 101, the sealing element being sealed inside the oil hole 101;

[0020] An oil hole 101 is provided at the center of the baffle body 100. A groove is formed by the inward recess of the rear surface of the baffle body 100. A sealing ring 120 is installed on the outer edge of the rear surface of the baffle body 100. The diameter of the sealing ring 120 is larger than the diameter of the oil hole 101.

[0021] The annular component includes an annular block 110. The annular block 110 is integrally formed on the front surface of the baffle body 100. The central axis of the annular block 110 is collinear with the central axis of the oil hole 101. The diameter of the sealing cover 200 is smaller than the diameter of the annular block 110. The outer surface of the sealing cover 200 is connected to the inner surface of the annular block 110.

[0022] The sealing cover 200 has a U-shaped cross section. The sealing cover 200 is installed inside the annular block 110. The sealing element includes a sealing block 220 and a sealing ring 210. The sealing block 220 is integrally formed at the center of the inner surface of the sealing cover 200.

[0023] When in use, if the user needs to seal, the user can install the sealing cap 200 of the sealing assembly on the front surface of the baffle body 100. At this time, the sealing cap 200 will be snapped onto the front surface of the baffle body 100 by the annular block 110. When the sealing cap 200 is snapped and fixed on the front surface of the baffle body 100, the sealing block 220 on the inner surface of the sealing cap 200 will also be snapped and fixed inside the oil hole 101, thereby fixing the sealing assembly on the front surface of the baffle body 100 and forming a sealing effect. Since the oil hole 101 is sealed by installing the sealing assembly on the inner surface of the baffle assembly during use, the lubricating oil in the gearbox can be effectively prevented from leaking from the oil hole 101, avoiding problems such as insufficient gear lubrication and accelerated wear caused by oil leakage.

[0024] Please see Figures 1 to 3 As a second embodiment of the present invention: based on the description in the above embodiments, the sealing block 220 is further annular in structure, and a sealing groove 221 is formed by inward recessing at the center of the outer surface of the sealing block 220. The cross section of the sealing block 220 is I-shaped, and the diameter of the sealing groove 221 of the sealing block 220 matches the diameter of the oil hole 101.

[0025] A sealing ring 210 is installed on the outer surface of the sealing groove 221 of the sealing block 220. The outer surface of the sealing ring 210 abuts against the front surface of the baffle body 100. The sealing block 220 is set inside the oil hole 101. The width of the sealing groove 221 matches the width of the oil hole 101. The sealing block 220 is fixed inside the oil hole 101 by the sealing groove 221.

[0026] In use, after the sealing cover 200 is installed inside the annular block 110 through the operation steps of the first embodiment, the sealing block 220, being a plastic structure with a sealing rubber structure, will be squeezed and fixed inside the oil hole 101. This causes the sealing groove 221 on the outer surface of the sealing block 220 to be snapped and fixed inside the oil hole 101, and the inner wall of the sealing groove 221 to abut against the sealing ring 120 and the sealing ring 210. Subsequently, the sealing ring 120 and the sealing ring 210 are squeezed and sealed against the baffle body 100. Then, the sealing block 220, together with the sealing groove 221, the sealing ring 120, and the sealing ring 210, seals the oil hole 101. In use, by setting the sealing block 220 inside the sealing cover 200 and tightly installing it inside the oil hole 101 to form a seal, the leakage of gearbox lubricating oil through the oil hole 101 can be effectively prevented, avoiding gear wear and equipment failure caused by insufficient lubrication.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
