Hinge shaft two-point lubrication rotatable joint

Abstract

The invention discloses a high shaft two-point lubrication rotatable joint. The two-point lubrication rotatable joint comprises a shell, an inner core, a first oil storage tank and a second oil storage tank. The two-point lubrication rotatable joint has the beneficial effects that by arranging the shell, the inner core, a connecting piece, a first oil inlet hole, a second oil inlet hole, a nylon guide plate, a first O-shaped ring, a second O-shaped ring, a third O-shaped ring, an oil seal, the first oil storage tank and the second oil storage tank, normal rotation of a hinge shaft can be guaranteed, meanwhile, lubricating sealing of the hinge shaft connecting lubricating part is achieved, overall rotation of the hinge shaft connecting lubricating part is effectively avoided, the use of a stainless steel pipe at the hinged shaft connecting lubricating part is facilitated, the attractiveness of the hinge shaft lubricating part is ensured, the service life of a protective part at the hinge shaft connecting lubricating part is prolonged, and meanwhile, the cost of hinge shaft lubricating connection is reduced; and by arranging a rotating groove, a bottom plate, a limiting table and an inserting hole, all parts of the whole rotating joint can be conveniently disassembled, the later-stage efficient overhaul and maintenance of the hinge shaft connecting lubricating part are facilitated, and the use flexibility of the rotating joint is greatly improved.

Description

technical field [0001] The invention relates to the technical field of double-point lubrication of hinge shafts, in particular to a rotatable joint for double-point lubrication of hinge shafts. Background technique [0002] In the port machinery industry, there are three ways to combine steel structures, one is two-two welding, the other is bolt connection, and the third is hinge connection. Among them, the hinge shaft connection method is most used on carts, rigid legs and flexible legs; for the lubrication industry, the hinge points of carts are relatively complicated, and there are many lubrications. The hinge point connection means two There is an amount of activity between the steel structures. This mutual movement will cause deformation, leakage, and rupture of the lubricated and connected stainless steel pipes, which will cause problems such as incomplete lubrication and grease leakage. With the development of technology, now Many hinge points on port machinery equip...

Problems solved by technology

Among them, the hinge shaft connection method is most used on carts, rigid legs and flexible legs; for the lubrication industry, the hinge points of carts are relatively complicated, and there are many lubrications. The hinge point connection means two There is an amount of activity between the steel structures. This mutual movement will cause deformation, leakage, and rupture of the lubricated and connected stainless steel pipes, which will cause problems such as incomplete lubrication and grease leakage. With the development of technology, now Many hinge points on port machinery equipment adopt the lubrication form of double lubrication points on one side of a single shaft. The advantage of this is that there is no relative movement in most parts of the hinge shaft. There is a new problem, that is, stainless steel pipes cannot be used for the lubricating part of the hinge shaft, which returns to the original problem

[0003] At present, the solution to the problem of the rotating hinge shaft in the market is to connect it with a rubber hose, and use the length of the rubber hose to ensure the ductility and freedom during the movement. However, such a lubrication method can reduce the impact of relative movement to a certain extent. But there are also great defects; for example: 1. The rubber hose is exposed to the wind and the sun for a long time, and it is bound to age faster than the steel pipe made of stainless steel, which shortens the service life of the protective parts of the lubricating parts connected to the hinge shaft; 2. The equipment Excessive use of upper rubber hoses results in serious unsightly joints on the joints of the hinge shaft; 3. The application of rubber hoses increases the number of pipe joints required and increases a lot of costs; in addition, the rubber hoses are mostly one-piece structures, which are inconvenient to disassemble. Greatly reduce the maintenance efficiency of the hinge shaft connection lubrication part in the later stage
