Based on above-mentioned technical scheme, the contact of steel ball and holder internal lock structure department is two small sections circular arc line contacts (the steel ball rides on holder pocket toper and lower columniform linking edge circular arc line promptly), it only has two small sections to link up edge circular arc line, reduce the frictional contact area, reduce the friction themogenesis, thereby reduce the bearing temperature rise, also reduce the holder simultaneously to the influence of steel ball autogyration and circumference rolling rotation, improve bearing operation flexibility, guarantee that the bearing is high-speed and high accuracy, also can reduce the bearing noise.
Furthermore, a plurality of outer diameter bosses are arranged on the outer diameter surface of the retainer, and one outer diameter boss is arranged between two adjacent pockets.
Furthermore, the outer diameter boss is arranged in the axial middle of the outer diameter surface of the retainer, and the axial length of the outer diameter boss is smaller than the diameter of the second cylindrical section.
Based on above-mentioned technical scheme, both can improve the intensity of holder roof beam, help realizing again that minimum nominal wall thickness realizes reducing frame weight, and holder structure bilateral symmetry is favorable to the dynamic balance when the bearing rotates simultaneously, improves bearing rotational speed and operating stability, reduces bearing noise.
Furthermore, a plurality of inner diameter bosses are arranged on the inner diameter surface of the retainer, and one inner diameter boss is arranged between two adjacent pockets.
Furthermore, two sides of each inner diameter boss are respectively provided with a first cylindrical section of the pockets at two sides of the inner diameter boss.
Furthermore, the inner diameter boss is arranged in the axial middle of the inner diameter surface of the retainer, and the axial length of the inner diameter boss is smaller than the diameter of the second cylindrical section.
Based on the technical scheme, in a limited space, the inner diameter boss has two functions, namely the strength of the frame beam is ensured while the minimum nominal wall thickness is realized, and two short inner diameter boss locking balls adjacent to the inner side in the circumferential direction are arranged. The width of the inner boss is the minimum value determined through calculation, the inner diameter of the inner boss is the maximum value, the strength of the retainer beam is improved, the weight of the retainer is reduced, the rotating speed and the running stability of the bearing are improved, and the working noise of the bearing is reduced.
Furthermore, the retainer is made of polyamide resin.
Based on the technical scheme, the material has proper drawability and high strength, has a certain oil storage function, provides feasibility for realizing structural lightness and thinness of the retainer from the aspect of materials, can improve the long service life performance and the lubricating performance of the retainer, reduces the friction heat of the steel ball and the retainer, reduces the temperature rise of the bearing, and enables the retainer to have high safety coefficient. Thereby ensuring the low temperature rise, high rotating speed, high precision, high bearing capacity and long service life of the bearing.
It should be noted that the holder may be made of other materials, such as brass and nylon.
To the further explanation of the utility model: the utility model adopts the minimum nominal wall thickness to reduce the weight of the retainer and the rotating centrifugal force of the retainer under the condition of structurally ensuring the strength of the two side beams of the retainer, thereby improving the rotating speed and the running stability of the bearing and reducing the working noise of the bearing; the retainer adopts a simple structure, the due strength and the drawing performance of the retainer can be ensured, the processing difficulty of a die can be reduced, the size of the locking amount of the pocket hole of the retainer is effectively reduced, the running stability of the bearing is further improved, the manufacturing cost of the die is effectively reduced, and the economic benefit is improved.
