Description

Technical Field

[0001] The utility model patent relates to an aircraft wheel bearing lubrication tool, in particular to a magnetic wheel bearing oiling machine. Background Art

[0002] Aircraft wheels are important parts of the landing gear. During takeoff and landing, the aircraft taxis at high speed, and the wheel speed is high, which generates friction and heat. In order to reduce friction, tapered roller bearings are usually used between the wheel and the axle to reduce friction, protect the wheel and axle from damage, and extend the service life of the landing gear and wheel. At the same time, during the landing process of the aircraft, the wheel can absorb part of the vertical load at the moment of landing. The wheel tapered bearing can convert part of the vertical longitudinal load into axial load, which plays a role in protecting the axle. It can be seen that aircraft wheel bearings are important parts of the wheel. After long-term use, wheel bearings are prone to hidden dangers such as grease contamination, increased sludge, roller drying, increased friction and even bearing frame breakage and damage. Therefore, during the maintenance of aircraft wheel components, the tapered bearings of the wheels need to be cleaned and lubricated regularly. Bearing lubrication mainly involves fully filling the inner and outer surfaces of the bearings and the gaps between the rollers and the inner rings of the bearings and the bearing frames and their joints with suitable brands of grease. The grease is required to be fully filled in all positions of the bearings, and all rollers must be fully soaked without leaving any cavities. The quality of bearing lubrication determines the service life of the bearings, and also has an important impact on the service life of the landing gear and wheels.

[0003] Oiling is a key step in the bearing maintenance process. In recent years, the bearing oiling method has gradually developed from the earliest manual application to the use of bearing oiling machines. The invention and use of bearing oiling machines have improved the oiling efficiency and oiling effect. At present, the bearing oiling machines on the market generally use pressure oiling, and the implementation method of pressure oiling is mainly to first fix and clamp the bearing on a special oiling mold, and then use pneumatic or electric booster to press the grease into the bearing so that the grease is fully filled. The advantages of this oiling method are good bearing oiling effect, comprehensive grease filling, and high oiling efficiency, but there are still certain shortcomings. For example, the pressure oiling method mostly uses electric or pneumatic oiling machines, and the use conditions of the oiling machine have power supply and gas supply requirements; and the operation of the oiling machine requires manual picking and placing of the bearing, and the oiling operation is controlled by the foot pedal, which requires hand and foot coordination, and there is a certain risk in the operation; in addition, this type of oiling machine generally has a complex internal structure and occupies a large space, which is not convenient to use and carry.

[0004] In order to solve the problems in the prior art, the technical solution adopted by the utility model is:

[0005] A magnetic wheel bearing oiling machine is provided, comprising a fixing component and an oiling component, wherein: the fixing component comprises a base plate, and an oil groove, a bearing positioning boss and a fixing bracket arranged on the base plate, and the bearing positioning boss is arranged in the oil groove; the oiling component comprises a magnetic suction cup, an oiling pipe, a lifting handle, an oil cavity, an oiling handle, and a refueling cap, the oil cavity is fixed on the fixing bracket, and lubricating oil can be injected into the oil cavity through the refueling cap, the magnetic suction cup can be pressed into the oil groove or pulled out of the oil groove by operating the lifting handle, and the lubricating oil in the oil cavity can be pressed out through the oiling pipe by operating the oiling handle.

[0006] When filling oil, first adsorb the wheel bearing on the lower surface of the magnetic suction cup (i.e., the side facing the oil tank), then operate the lifting handle to press the magnetic suction cup into the oil tank, and the wheel bearing enters the oil tank with the magnetic suction cup, and cooperates with the bearing positioning boss to be positioned and fixed, push the oil filling handle to open the oil cavity, and the lubricating oil in the oil cavity is pressed out to the inside of the bearing through the oil filling pipe until the entire bearing is filled. After the oil filling is completed, operate the lifting handle again to move the magnetic suction cup out of the oil tank, and the bearing after oil filling and lubrication can be removed.

[0007] Furthermore, the oil tank is cylindrical, the magnetic suction cup is disc-shaped, and the outer side of the magnetic suction cup is in contact with the inner wall of the oil tank.

[0008] Furthermore, the bearing positioning boss is cylindrical and is located at the center of the oil groove. Its shape matches the bearing and can position and fix the bearing.

[0009] Furthermore, the fixing assembly also includes a lifting handle bracket arranged on the bottom plate, and the middle part of the lifting handle is fixed to the lifting handle bracket and can be rotated around a fixed point in a lever-like manner.

[0010] Furthermore, the lifting handle bracket is provided with a fixing pin, and the fixing pin can keep the lifting handle fixed at a specific position.

[0011] Preferably, an oil filling nozzle is provided between the oil filling pipe and the magnetic suction cup.

[0012] Preferably, the bottom plate is made of resin material.

[0013] Preferably, the oil tank is made of non-metallic, oil-resistant and corrosion-resistant material.

[0014] The utility model adopts a magnetic wheel bearing oiling machine, which oils the bearing by manually operating a lifting handle to apply pressure, and uses the suction of a magnetic suction cup to pick up and place the bearing, thereby improving the convenience of operation. Compared with the electric or pneumatic oiling equipment in the prior art, while ensuring the oiling effect, the utility model has a reasonable structure, is lightweight, and has high operational safety. Moreover, compared with other oiling tools that require a certain amount of lubricating grease to be placed in the oil tank, the utility model provides an oil cavity on the oiling component, and no lubricating grease is required in the oil tank, which effectively avoids grease pollution and can save lubricating grease and avoid waste. In addition, the utility model has the characteristics of simple structure, small size, light weight, and easy carrying, which solves the problems of large size, complex structure, certain danger in operation, and high energy consumption of the existing oiling machine.
