Shedding mechanism of spacing link lever used for loom

Abstract

The invention provides a shedding mechanism with a spatial linkage used for a weaving machine. The shedding mechanism mainly comprises a small belt wheel, wherein the small belt wheel is fixedly connected with a main shaft; the small belt wheel is connected with a large belt wheel fixed on a crank shaft through a synchronous belt; the crank shaft is arranged on a machine frame through a bearing; one end of the spatial linkage is connected with the crank shaft through the bearing, while the other end o is connected with a swinging arm through the bearing; the included angle of axial leads of bearings on two ends of the spatial linkage is 90 degrees; the swinging arm is connected with a swinging axis arranged on the frame through the bearing, while the swinging axis is connected with a tracing frame through a linkage mechanism; the spatial linkage and the crank shaft can rotate relatively around the axial lead of an intermediate bearing; the spatial linkage and the swinging arm also canrotate relatively through the axial lead of a tapered roller bearing in the middle; the swinging arm rotates around the axial lead of the swinging axis; and the axial lead of the intermediate bearing, the axial lead of the tapered roller bearing, the axial lead of the crank shaft and the axial lead of the swinging axis are crossed in a point. The shedding mechanism has the characteristics of simple and compact structure, convenient use, good reliability, cost conservation and the like.

Description

technical field

[0001] The invention relates to a shedding mechanism specially used for looms to realize loom shedding movement, and belongs to the technical field of textile machinery. Background technique

[0002] In the prior art, the composition of the shedding mechanism that loom is used sees attached figure 1 As shown, it mainly includes a driving pulley 102 fixedly connected with the main shaft 101, and the main shaft 101 is connected with the frame through bearings. A driven pulley 104 and the bevel pinion 105 are respectively fixed on the two ends of the bevel pinion shaft 106, and the bevel pinion shaft 106 is connected with the frame through a bearing. The large bevel gear 107 and the cam are respectively fixed on the two ends of the large bevel gear shaft 108, the large bevel gear shaft 108 is connected with the frame through bearings, the upper roller 110 and the lower roller 111 are connected with the swing arm 112 through the bearings, and are connected with ...
