[0002] The PEEK cage of the bearing is a cage made of polyetheretherketone (PEEK) material. PEEK is a high-performance engineering plastic with excellent high temperature resistance, chemical corrosion resistance, wear resistance and fatigue resistance. Therefore, the PEEK cage of the bearing has high mechanical strength and durability, and can maintain good performance in harsh environments such as high temperature and chemical corrosion.

[0003] However, the PEEK bearing cages currently on the market still have the following shortcomings: the existing PEEK bearing cages have poor thermal conductivity, which is not conducive to the heat dissipation of the balls and bearings, and may affect the service life of the balls and bearings; and the existing PEEK cages are prone to aging under ultraviolet rays, so when used outdoors in sunlight conditions, their performance and life may be affected.

[0009] As a preferred solution of the utility model, the anti-aging layer is a titanium dioxide nano-coating, which is arranged on the outer surface of the retaining frame body through a coating process.

[0010] As a preferred solution of the utility model, the anti-deformation layer includes a carbon fiber material layer and a ceramic fiber layer, and a polypropylene material layer is fixed between the carbon fiber material layer and the ceramic fiber layer.

[0011] As a preferred solution of the utility model, the reinforcement layer is provided with first reinforcement ribs and second reinforcement ribs in a regularly distributed manner inside, and the first reinforcement ribs and the second reinforcement ribs are both made of high-strength reinforcement rib material.

[0012] As a preferred solution of the utility model, the outer ends of the first reinforcing ribs and the second reinforcing ribs are integrally fixedly connected to the inner wall of the retaining frame, and the first reinforcing ribs and the second reinforcing ribs are cross-arranged to form a triangular support structure.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] In the utility model, an integrated bearing PEEK retainer is provided. When the bearing PEEK retainer is used, on the one hand, the ventilation duct formed between the heat-conducting notch and the heat-dissipating hole can be utilized so that part of the heat inside the installation notch can be discharged from the ventilation duct to the external environment, thereby avoiding the situation that part of the heat cannot be discharged due to the obstruction of the ball and eventually accumulates on the ball, which eventually affects the service life of the ball; on the other hand, the titanium dioxide nano-coating on the anti-aging layer can resist ultraviolet rays in the external environment, thereby avoiding the hidden danger of easy aging of the PEEK retainer under ultraviolet rays, and the utility model is more practical.
