OPERATING MECHANISM OF ENGAGING SLEEVE SHIFTING AT ROTARY CENTRE

摘要

Disclosed is an operating mechanism of an engaging sleeve shifting at a rotary centre, comprising a moving drawbar (1), an engaging sleeve (2), a right gear (3), a main rotary shaft (4), a left gear (5), a spring pin (6), a rapid selection seat (7), and a steel balls (8), wherein the left gear (5) and the right gear (3) respectively are fixedly mounted on an outer ring of the main rotary shaft (4) by means of a bushing; the engaging sleeve (2) is connected to the rapid selection seat (7) by means of the spring pin (6); the rapid selection seat (7) is mounted in the main rotary shaft (4); and the rapid selection seat (7) is connected to the moving drawbar (1) by means of the steel balls (8) mounted thereupon. The operating mechanism of an engaging sleeve shifting at a rotary centre can make the arrangement of a transmission system more compact and the connections thereof more reliable.
