Description

Technical Field

[0001] This invention relates to the field of sliding bearing technology, and in particular to a tooling for cleaning the oil grooves of sliding bearing bushes. Background Technology

[0002] A sliding bearing operates under sliding friction. Under liquid lubrication, the sliding surfaces are separated by lubricating oil, preventing direct contact and significantly reducing friction loss and surface wear. The oil film also provides some vibration damping. The portion of the shaft supported by the bearing is called the journal, and the part that mates with the journal is called the bearing bush. The friction material layer cast onto the inner surface of the bearing bush to improve its frictional properties is called the bearing liner. Oil grooves are created in the bearing bush to evenly distribute the lubricating oil between the journal and the bearing's working surfaces.

[0003] In the operation of sliding bearings, when friction occurs between the bearing retainer of the shaft and the thrust surface of the bearing bush, the bearing bush temperature rises and the bearing liner material is worn away. Since there is no gap between the bearing retainer of the shaft and the thrust surface of the bearing, the worn-away material of the bearing liner will be squeezed onto the thrust surface of the bearing to form a film, and then squeezed into the oil groove. When the bearing is disassembled and the bearing bush is cleaned, due to the lack of suitable tooling to clean the rubbed material in the oil groove, it will be difficult to clean or not clean it thoroughly. This will have an adverse effect on the subsequent operation of the sliding bearing, making it difficult to guarantee product quality and production efficiency. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the present invention provides a tooling for cleaning the oil groove of sliding bearing bush, which overcomes the shortcomings of the prior art and effectively solves the problem that the oil groove is difficult to clean and cannot be cleaned thoroughly.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A tooling for cleaning the oil groove of a sliding bearing bush includes an oil groove cleaner. The oil groove cleaner has a grip sleeve inside, and a first connector plate is connected to one outer wall of the grip sleeve. Limiting plates are provided on the top and bottom outer walls of the first connector plate. A cleaning plate is rotatably connected to the inner wall of the first connector plate, and a tapered tooth groove is opened at one end of the bottom outer wall of the cleaning plate. A cleaning cloth is adhered to the top outer wall of the cleaning plate.

[0007] A second connector plate is connected to the outer wall of the other side of the grip, and symmetrically distributed round rods are installed on one side of the outer wall of the second connector plate. A spoon head is welded to the outer wall of one end of the round rod.

[0008] Preferably, a groove is formed on the outer wall of one side of the spoon head.

[0009] Preferably, the rotation angle of the cleaning plate between the two limiting plates is 0-20°.

[0010] Preferably, the outer walls on both sides of the grip sleeve are provided with finger positioning grooves that are evenly distributed.

[0011] Preferably, the top and bottom outer walls of the cleaning plate are provided with index finger pressing plates.

[0012] Preferably, the oil tank cleaner is provided with a bearing shell on its exterior, and the outer wall of the top of the bearing shell is provided with bearing shell oil grooves distributed at equal intervals.

[0013] Preferably, the size of the cleaning plate is adapted to the size of the bearing oil groove.

[0014] The beneficial effects of this invention are as follows:

[0015] 1. The tooling for cleaning the oil groove of sliding bearing bush of the present invention has both removal and cleaning functions, which can solve the problems of inconvenience in cleaning the oil groove on site, low cleaning efficiency and poor cleaning effect. The tooling design is simple in structure and easy to use. At the same time, it has reference value for other occasions with cleaning needs, and has certain application value and promotion significance.

[0016] 2. The tooling for cleaning the oil groove of sliding bearing bush of the present invention allows the cleaning plate to tilt up and down at a certain angle under the action of two limiting plates during use. This conforms to ergonomics, making it easier for operators to clean the waste residue in the oil groove of the bearing bush, saving more effort and reducing the difficulty of cleaning.
