一种带保护装置的轨道螺母
摘要：
一种带保护装置的轨道螺母，包括螺母本体、钢珠，在螺母本体的内壁上开设有至少一个横向半楔型槽，该横向半楔型槽匀沿螺栓旋入方向由浅而深，并且每个横向半楔型槽较深一侧预设弹簧，较浅的一侧活动放置钢珠。本发明由于省去螺母本体的环型深槽，降低螺母成本，安装时也省去了在环形深槽内嵌放防松环的步骤，而且由于弹簧的作用，使钢珠始终被顶向横向半楔型槽较浅的一端，从而保证钢珠与螺栓始终配合作用，提高防盗功能。
摘要（英）：

A track nut with a protective device comprises a nut body and steel balls, and the inner wall of the nut body is provided with at least one transverse half wedged slot; all the transverse half wedgedslots are from shallow to deep in the screwing direction of bolts, and a spring is preinstalled on the deeper side of each transverse half wedged slot; and the shallower side of each transverse half wedged slot is provided with the steel balls. According to the track nut, since a ring deep groove of the nut body is omitted, the nut cost is reduced, and the step of embedding a lock ring in the ringdeep groove is further omitted during installation; and the steel balls are jacked to the shallower end of the transverse half wedged slot all the time under action of the springs, so that the cooperation effect of the steel balls and the bolts is ensured all the time, and the anti-theft function is improved.
