Abstract

The invention discloses a trapezoid self-locking pin bearing retainer. The retainer is of a cylindrical structure and comprises multiple locking pin opening units, wherein the locking pin opening units are uniformly arrayed along the circumference of the retainer; each locking pin opening unit comprises two bar-shaped locking pin openings which are of the same shape and size and are in parallel with the axis of the retainer; the two locking pin openings are separated by a bar-shaped window beam which is arranged in the middle of the retainer and extends along the circumferential direction; each locking pin is formed between two adjacent bar-shaped window bars; trapezoid bosses are arranged at two ends of each window bar; clamping openings for clamping rolling pins are formed between bosses of the two adjacent window bars and are distributed along the circumference of the cylindrical retainer. The invention further provides a blanking die for manufacturing the trapezoid self-locking pin bearing retainer. The trapezoid self-locking pin bearing retainer has the advantage of uniform shapes of self-locking structures, no welding point, high intensity and long service life.

Description

technical field [0001] The invention relates to the field of needle bearings, in particular to a trapezoidal self-locking needle bearing cage and a blanking die. Background technique [0002] Needle roller bearings or roller bearings are required in many places in the field of construction machinery and heavy-duty vehicles. For example, in medium and heavy-duty vehicle gearboxes, needle bearings are used in each gear. The function of the needle bearing is to guide the gear to rotate. Because most of the needle roller bearings are of M-type structure, the needle roller bearings of the M-type structure are easy to be damaged due to the thinner wall thickness of the cage and insufficient strength, resulting in early failure of the bearing and serious consequences. Therefore, there is an urgent need to provide a high-strength, long-life needle roller bearing cage. [0003] In addition, in the prior art, two methods are generally used to manufacture needle roller bearing cages....
