[0009] As a further scheme of the utility model, the plastic body oil has saturated lubricating oil adsorbed inside, during operation, the lubricating oil moves to the surface of friction pair under the action of capillary action, forming a lubricating oil film, and when stopping operation, the lubricating oil is reabsorbed into the polymer and stored.

[0010] As a further scheme of the utility model, the plastic body oil is formed by mixing polyethylene PE, ultra-high molecular weight polyethylene, polyimide or PEEK polymer as matrix material with lubricating oil and additives to form a viscous fluid lubricating medium, which is injected into the bearing by injection molding, molding or vulcanization, and then hardened to form a porous oil-containing lubricating material. These micropores can accommodate lubricating oil and retain it in the material through surface tension.

[0011] The utility model has the following beneficial effects:

[0012] The cross universal joint bearing provided by the utility model can realize maintenance-free of the cross universal joint, solves the problems of pollution and oil leakage, greatly reduces the equipment maintenance cost caused by oil filling, does not need to add a self-lubricating device, the cross shaft also does not need an oil storage cavity, and the lubricating oil can be stored after use, so that it is not necessary to continuously add lubricating oil, unlike other powder lubricating materials which are continuously consumed, so that the use cycle is obviously reduced.

[0013] To make the structural features and effects of the utility model clearer, the utility model will be described in detail below in combination with the drawings and specific embodiments. BRIEF DESCRIPTION OF DRAWINGS

[0014] Figure 1 It is a cross universal joint bearing structure schematic view of prior art;

[0015] Figure 2 It is a cross universal joint bearing of the utility model; DETAILED DESCRIPTION

[0016] The utility model will be further described below in combination with the drawings and related knowledge, and is described clearly and completely, obviously, the described application is only a part of the embodiments of the utility model, not all the embodiments.

[0017] Referring to Figure 1 As shown in the figure, the cross universal joint bearing of prior art comprises a cross shaft 1, an oil cup 2 and an inner needle bearing 3, needs to be regularly or continuously oiled during movement, the lubricating oil leaks seriously, the equipment is polluted, needs to be regularly cleaned, and if the oiling is forgotten, the cross joint will be seriously worn and damaged. Embodiment 1

[0018] The cross universal joint bearing of the utility model comprises a cross shaft 1 and a plurality of bearings 4 arranged on the cross shaft, the bearing 4 is provided with a containing space 5 for containing plastic body oil 6, further preferably, the cross shaft is provided with a spiral groove, a circular groove, a circular hole and other various containing spaces 5 at the bearing cooperation shaft, the plastic body oil is inlaid at the containing space 5, so that the cross joint can continuously maintain the oil lubrication state during movement, and the oil will not overflow; the cross universal joint bearing can continuously discharge oil during movement, maintains the oil lubrication state and the oil will not overflow. The utility model does not need to add a self-lubricating device, the cross shaft also does not need an oil storage cavity, and the lubricating oil can be stored after use, so that it is not necessary to continuously add lubricating oil, unlike other powder lubricating materials which are continuously consumed.

[0019] In this example, see Appendix Figure 2 The accommodating space is an annular groove structure or a recessed structure; more preferably, the accommodating space is a number of annular groove structures or a number of recessed structures spaced apart, and the number of recessed structures are evenly distributed along the circumference of the bearing. That is to say, it can be used for embedding or injection molding of plastic body oil in the entire ten-byte structure, and is not limited to the annular groove structure or recessed structure mentioned above.

[0020] This invention utilizes a polymer-based lubricant that internally absorbs saturated lubricating oil. During operation, the lubricating oil moves towards the friction pair surface under capillary action, forming a lubricating oil film. When operation stops, the lubricating oil is reabsorbed into the polymer and stored, eliminating the need for a self-lubricating device. Furthermore, the cross shaft does not require an oil reservoir. The lubricating grease can be stored after use, eliminating the need for continuous refilling, unlike other powder lubricants which are constantly depleted. This significantly reduces the service life. The polymer-based lubricant lubricates the friction area, and during continuous friction, the lubricating material remains within the friction area, ensuring the friction pair is always lubricated and under effective lubrication conditions, thus eliminating the need for additional lubrication and achieving a maintenance-free effect.

[0021] In this invention, the plastic oil is made of polyethylene (PE), ultra-high molecular weight polyethylene, polyimide, or PEEK polymer as the base material, mixed with lubricating oil and additives to form a viscous fluid lubricating medium. After being injected into the bearing through injection molding, compression molding, and vulcanization, it is cured by heating to form a porous oil-containing lubricating material. These micropores can accommodate the lubricating oil and retain it in the material through surface tension. The specific form is not particularly limited, as long as it conforms to the morphology of the plastic oil, it meets the requirements of this invention.

[0022] Furthermore, in Figure 2 In the process, different bearings 4 can be provided with receiving spaces 5 of different shapes, such as groove or ring structure, and then plastic oil is embedded in the receiving space 5.

[0023] It should be noted that the lubrication method of the plastic body oil of this utility model is applicable to all joint bearings.

[0024] Compared with existing technologies, the universal joint bearing with embedded plastic oil described in this utility model has the following advantages: excellent heat resistance and self-lubrication; it can be injection molded and is environmentally friendly and pollution-free; it can be mass-produced, reducing costs. It achieves maintenance-free operation during use, reducing after-sales maintenance costs and extending product lifespan.

[0025] Although the part embodiments of the utility model have been shown and described, for the ordinary skilled in the art, it can be understood that can make multiple changes, modification, replacement and variation to these embodiments without departing from the principles and spirits of the utility model, all should belong to the scope of the utility model.
