Abstract
A transmission cam for thread needle of sewing machine comprises a vertical transmission cam and a posteroanterior transmission cam, an outer sleeve is arranged at the periphery of the transmission cam which contacts with the transmission swing rod directly. The utility model is characterized by easy processing, small transmission friction as well as low operation noise.
Description
The utility model relates to the parts on the sewing machine, specifically is that the concavo-convex of knee-action taken turns before and after being used for driving the line pin.
The concavo-convex structure of taking turns of band line pin transmission on the sewing machine is at present: the overcoat of an identical concavo-convex curve is respectively arranged in a pair of concavo-convex both sides, outer of taking turns, and a side of this overcoat connects with a side of corresponding concavo-convex outer of taking turns.The concavo-convex processing and manufacturing difficulty of taking turns of this structure, gearing friction is big, and operating noise is big.
The purpose of this utility model just provides a kind of easy processing, the concavo-convex wheel of sewing machine band line pin transmission that gearing friction is little.
The technical solution of the utility model is: the overcoat that removes both sides, prior art concave cam outer, its structure comprises that concavo-convex the wheel with the front and back transmission is concavo-convex of underdrive take turns, separate slot is arranged between the two, and its both sides, outer are the plane, and the concavo-convex outer of taking turns directly contacts with the transmission fork.
The utlity model has handling ease, gearing friction is little, operating noise is little characteristics.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model.
Referring to Fig. 1, structure of the present utility model comprises that underdrive is concavo-convex and takes turns 1 and the front and back transmission is concavo-convex takes turns 2, and separate slot 5 is arranged between the two, and they are fixed on the power transmission shaft 3, and its both sides, outer are planes, do not have overcoat, are directly contacted with transmission fork 4 by concavo-convex outer.Because the face of separating that connects between the two has only a bit (side), its friction reduces, and noise also diminishes.And the end of transmission fork is positioned at concavo-convex groove of taking turns 1 and 2 both sides in the prior art, a week of the end of the moving all transmission forks of revolution all will with above-mentioned groove two walls friction, so its abrasion is big, noise is also big.
Claims (1)
- The concavo-convex wheel of a kind of sewing machine band line pin transmission comprises that concavo-convex the wheel with the front and back transmission is concavo-convex of underdrive take turns, and separate slot is arranged between the two, and it is characterized in that: its both sides, outer are the plane, and the concavo-convex outer of taking turns directly contacts with the transmission fork.
