Description

Technical Field

[0001] The present application relates to the technical field of bearings, and in particular to an anti-deformation plastic bearing retainer. Background Art

[0002] The working surfaces of plastic sliding bearings generally have self-lubricating functions; plastic sliding bearings are generally made of engineering plastics with relatively good performance; more professional manufacturers generally have self-lubricating modification technology for engineering plastics, and use fibers, special lubricants, glass beads, etc. to enhance the self-lubrication of engineering plastics to achieve certain performance, and then use the modified plastics through injection molding to make self-lubricating plastic bearings.

[0003] Compared with metal, plastic materials have some limitations in performance, especially when running at high speed or bearing large loads. The heat generated by friction may cause the plastic material to soften or deform, resulting in a gap between the ball holder and the ball, which can easily cause the ball to shake, thereby increasing the wear between the ball and the ball holder, and increasing the rotational resistance of the inner ring. In severe cases, the ball can easily fall out of the ball holder. Utility Model Content

It solves the problem that the heat generated by friction may cause the plastic material to soften or deform, thereby causing a gap between the ball holder and the ball, which easily causes the ball to shake, thereby increasing the wear between the ball and the ball holder, and at the same time increasing the rotational resistance of the inner ring. In severe cases, the ball may easily fall out of the ball holder.

[0005] To achieve the above-mentioned purpose, the present application provides the following technical solutions: an anti-deformation bearing plastic retainer, comprising a frame body, the upper surface of the frame body is provided with a plurality of ball grooves arranged at equal distances in a circle, a ball holder is fixedly embedded in the interior of each ball groove, and pressure plates are fixedly connected to the two side surfaces of each ball holder;

[0006] An inlay groove is provided on the upper surface of the frame, a connecting sleeve is fixedly connected inside the inlay groove, a thread is arranged inside the connecting sleeve, a fixing rod is threadedly connected inside the connecting sleeve, a rotating disk is rotatably connected to the top end of the fixing rod, and two extrusion blocks are fixedly connected to the outer surface of the rotating disk.

[0007] Through the above scheme, a portion of the lubricating oil can be stored through the oil storage tank, which is convenient for the subsequent continuous lubrication of the ball. The extrusion block can squeeze the pressure plates on both sides of the ball holder close to each other during the rotation, so that the ball holder and the ball are in close contact. At the same time, the extrusion block can enter the interior of the bayonet to limit and support the pressure plate, thereby preventing the ball holder from deforming and expanding outward after being subjected to load and heat, thereby effectively ensuring the close fit between the ball and the ball holder.

[0008] Furthermore, an oil storage tank is provided inside each of the ball holders.

[0009] Through the above scheme, by setting the oil storage tank, the lubricating oil can be stored, thereby improving the lubrication effect of the external ball.

[0010] Furthermore, a plum blossom groove is formed on the upper surface of each fixing rod.

[0011] Through the above solution, the setting of the hexalobular slot makes it convenient for the user to use an external screwdriver to rotate the fixing rod.

[0012] Furthermore, a bayonet is provided on the upper surface of each of the pressure plates.

[0013] Through the above scheme, by setting the bayonet, it is possible to facilitate the entry of the extrusion block, thereby achieving the purpose of limiting the extrusion block.

[0014] Furthermore, the edges of the sides of each two adjacent pressure plates close to each other are rounded, and the end of each extrusion block away from the fixing rod is rounded.

[0015] Through the above scheme, by setting the rounded corners of the extrusion block and the pressure plate, the purpose of moving the pressure plate by extruding it can be achieved when the extrusion block rotates and contacts the pressure plate.

[0016] Furthermore, a knob is fixedly connected to the upper surface of each rotating disk.

[0017] Through the above solution and the setting of the knob, it is convenient for the user to rotate the rotating disk.

[0018] Furthermore, the threads inside each connecting sleeve are self-locking threads.

[0019] Through the above solution, by setting the self-locking thread, it is possible to prevent the fixing rod from loosening.

[0020] Furthermore, the frame and each of the ball holders are made of plastic.

[0021] Through the above solution, by setting the frame and the ball holder with plastic materials, the overall weight can be reduced and the cost can be reduced.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] The anti-deformation bearing plastic retainer can store part of the lubricating oil through the oil storage tank, which is convenient for the subsequent continuous lubrication of the ball. The extrusion block can squeeze the pressure plates on both sides of the ball holder close to each other during the rotation, so that the ball holder and the ball are in close contact. At the same time, the extrusion block can enter the interior of the bayonet to limit and support the pressure plate, so as to avoid the ball holder from deforming and expanding outward after being subjected to load and heat, thereby effectively ensuring the close fit between the ball and the ball holder.
