Front bar cradle cam

Abstract

The invention belongs to the technical field of warp knitting machine components, in particular to a front guide bar cradle cam of a multi-guide-bar warp knitting machine. The front guide bar cradle cam comprises a wheel disk and a journal arranged on the end face of one side of the wheel disk and integrated with the wheel disk, the journal is connected with a camshaft, the peripheral surface of the wheel disk is an external motion cycle curved surface, an internal motion cycle curved surface conjugated with the external motion cycle curved surface is further arranged on the end face on the other side, opposite to the journal, of the wheel disk, the internal motion cycle curved surface is a leading curved surface for having control over cycle motion of a front guide bar cradle, the internal motion cycle curved surface and the external motion cycle curved surface are respectively composed of a rapid ascending segment, a slow ascending segment, a pause segment and a rapid descending segment, and the motion segments of the internal motion cycle curved surface or the external motion cycle curved surface are in smooth transition. The front guide bar cradle cam is reasonable and compact in structure, and the radian of the control curved surface is gradual; in the control transmission process, impact is small, abrasion is low, transmission is stable, and the front guide bar cradle cam is applicable to high-speed control transmission, meets the requirement for high-speed running of the warp knitting machine, and is high in efficiency.

Description

technical field [0001] The invention belongs to the technical field of warp knitting machine components, in particular to a front bar cradle cam of a multi-bar warp knitting machine. Background technique [0002] The operation of the front bar of the warp knitting machine is mainly controlled by the front bar cradle cam and a series of transmission parts. The existing front bar cam structure is unreasonable, the curved surface arc for controlling transmission is relatively steep, and the span of the cam is too large. Moreover, the existing cams generally use the outer peripheral surface of the wheel disc as the main control surface, and the outer peripheral surface control requires multiple cams to be used in combination. The structure is complex. During the high-speed drive control transmission process, the vibration is very serious, the impact is large, easy to wear, and the transmission is unstable. , the operation stability of back bar is poor, and control transmission s...

Moreover, the existing cams generally use the outer peripheral surface of the wheel disc as the main control surface. The outer peripheral surface control requires a combination of multiple cams, and the structure is complex. During the high-speed drive control transmission process, the vibration is very serious, the impact is large, easy to wear, and the transmission is unstable. , the stability of the operation of the rear bar is poor, and the control transmission speed is low, which does not meet the needs of the high-speed operation of the current warp knitting machine, and the efficiency is low
