Description

Technical Field

[0001] This utility model discloses a permeation-type adaptable oiling fixture, which belongs to the field of adhesive coating business. Background Technology

[0002] Currently, automotive electric power steering systems often employ a gear shaft and rack meshing together to convert the rotational motion of the gear into the reciprocating motion of the rack, transmitting steering power and achieving steering operation, thus satisfying the requirements of easy steering at low speeds and stable steering at high speeds.

[0003] During the meshing process between the gear shaft and rack, the pressure and friction between them generate heat. Without proper grease distribution, this will accelerate wear on both and cause instability in the entire mechanical system. Too little grease will result in uneven distribution, while too much grease will lead to wasted resources and contaminate surrounding components.

[0004] Existing methods for applying grease to gear shafts mostly involve coating the grease onto the surface of the gear shaft and then transferring it between the teeth using a scraping motion. Due to the adhesive nature of grease, it is not possible to effectively distribute the grease to the tooth root or to uniformly coat the designated area with a fixed amount of grease, which affects subsequent processes and long-term reliable use. Summary of the Invention

[0005] To solve the above problems, this utility model provides a permeable, adaptable oiling fixture.

[0006] To achieve the above functions, the present invention adopts the following technical solution:

[0007] A permeable adaptable oiling fixture is provided, including an oil stop plate, an oil stop pad, an oil sealing shell, an oil sealing plate, a fixture base plate, an oil seepage plate, a one-way valve, a throttle valve, and an adjusting wrench, etc., characterized in that the oil seepage plate and the oil sealing plate can be adjusted to adapt to the gear shaft, and the oil seepage plate can uniformly permeate grease.

[0008] The adjusting wrench is U-shaped, with studs at both ends that are equidistant from the oil seepage plate and the oil sealing plate. This adjusting wrench allows adjustment of the positions of the oil seepage plate and the oil sealing plate on the oil sealing shell, thus accommodating gear shafts of different axial dimensions.

[0009] The throttle valve is a necessary component for adjusting the flow rate and stabilizing the grease penetration rate.

[0010] The one-way valve can lock the amount of oil entering the oil sealing shell to prevent the pressure inside the oil sealing shell from exceeding the external supply pressure and causing grease backflow.

[0011] The oil seepage plate has external threads on the upper part, and its position in the oil sealing shell can be adjusted to match the oiling length requirements of the gear shaft; the lower part has uniformly distributed through holes of gradually changing size, so that grease can stably and evenly fill the gear teeth through the through holes on the oil seepage plate; the middle part has a structure that fits with the gear shaft with clearance, so that the gear shaft is accurately positioned in the tooling.

[0012] The oil sealing plate has a clearance fit with the gear shaft at the top to effectively shield the area where coating is prohibited; the bottom has external threads, and its position inside the oil sealing shell can be adjusted to fit gear shafts of different lengths; the bottom has evenly distributed through holes to allow grease to enter the closed space formed by the oil sealing shell, the oil sealing plate, the oil seepage plate, the oil stop pad, and the oil stop plate.

[0013] The oil sealing shell has internal threads and a set screw on the side, allowing the oil sealing plate and oil seepage plate to be adjusted and then locked; the lower part forms a grease buffer space with the tooling base plate through a sealing ring.

[0014] The oil-stop pad is a soft material that is interference-fitted with the gear shaft. It, together with the oil-permeable plate and the oil-sealing plate, forms a closed space to effectively shield the area where coating is prohibited.

[0015] The oil stop plate is a rigid material that fixes the oil stop pad and can suppress the deformation of the oil stop pad. Attached Figure Description

[0017] Figure 1 In the middle: 1 is the oil stop plate; 2 is the oil stop gasket; 3 is the oil sealing shell; 4 is the oil sealing plate; 5 is the tooling base plate; 6 is the oil seepage plate; 7 is the one-way valve; 8 is the throttle valve; 9 is the adjusting wrench. Detailed Implementation

[0018] Install the oil sealing plate into the appropriate position on the oil sealing shell using an adjusting wrench, and secure it with a set screw; install the one-way valve onto the oil sealing shell, and connect the throttle valve through a pipeline; fix the oil sealing shell to the tooling base plate, and seal the two together with a sealing ring.

[0019] Fix the oil-stop pad and oil-stop plate together onto the oil-seeping plate. Adjust the position of the oil-seeping plate, oil-stop pad, and oil-stop plate according to the coating requirements of different gear shafts by adjusting the wrench. After matching, fix them with the set screw.

[0020] The gear shaft is passed sequentially through the oil stop plate, oil stop pad, and oil seepage plate to the oil sealing plate and placed there. A fixed amount of grease is introduced into the tooling. The grease enters between the tooling base plate and the oil sealing plate through the throttle valve and the check valve. Then the grease enters between the oil sealing shell, the oil seepage plate, the oil stop pad, and the oil stop plate. Finally, the grease evenly fills the gear shaft teeth through the oil seepage plate, achieving the ultimate goal of effectively lubricating the gear shaft and rack and reducing their wear.
