Self-aligning universal bearing

Abstract

The invention discloses a self-aligning universal bearing. The self-aligning universal bearing comprises a seat body, wherein a circular groove is formed in the seat body, a circular disc is arrangedin the circular groove, a plurality of steel balls are arranged between the side edge of the circular disc and the inner wall of the circular groove in an inlaid mode, and a rod end body is arranged at the top of the circular disc; and the rod end body penetrates through the seat body to extend to the position above the seat body, a hollowed-out through hole is formed in the upper part of the rodend body, a movable hole penetrating ball is arranged in the through hole, and a self-lubricating component is arranged between the hole penetrating ball and the rod end body in an inlaid mode. The self-aligning universal bearing has the beneficial effects that besides the functions of rotating and swinging of a common bearing, a head part and a handle part of the seat body are designed and manufactured in a split mode, the head part can perform 360-degree rotation action in the handle, and the firing dead angle is completely eliminated.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to a self-aligning universal bearing. Background technique [0002] In harsh environments such as alpine and desert, which are not suitable for soldiers to guard, or which are likely to cause casualties of one's own personnel, realizing automatic guarding or shooting of firearms has always been a key scientific research project in the military industry. The key breakthrough direction of reducing supply and difficulty is conducive to the realization of unmanned and automated defense and confrontation. Especially in the environment of high cold, desert and war, the significance is even more significant. [0003] However, at present, the automatic guarding and shooting range of firearms is basically limited to within 22 degrees of the center line of the gun barrel. When automatic guarding and shooting are carried out in a large area, the number of firearms required will increase grea...

AI Technical Summary

Problems solved by technology

At present, only the steel balls inside the bearings on the market have the function of rotation and a small amount of self-aligning swing, but the bearings are fixed after installation, and the swing angle of the entire product is completely determined by the steel balls inside, and the swing angle of the steel balls inside Generally, it is within 11 degrees, which cannot meet the requirements of the large holding angle of unattended firearms (above 90 degrees)
