An oil core 16 is stretched between the hook shaft base 8 and the hook shaft gear 6. The vicinity of the lower end of the oil core 16 is fixed to the hook shaft base 8 by a fixing means, for example, an oil core support 18, and the vicinity of the upper end of the oil core 16 is fixed to the frame of the sewing machine by the same fixing means (not shown). Can be fixed to the part.
[0015]
The oil core 16 absorbs the lubricating oil flowing out from the discharge hole 22 of the hook shaft base 8 near the lower end thereof, and can supply the absorbed lubricating oil to the meshing portion between the hook shaft gear 6 and a driving gear (not shown). Placed in.
[0016]
The lubricating oil that has served to lubricate the hook drive mechanism gears falls to the oil pan 14 below.
The lubricating oil in the oil pan 14 is reused after being filtered by the sponge-like filter 20 to remove lint and the like.
[0017]
【The invention's effect】
According to the present invention, in an oil supply device for a horizontal hook having an oil supply path formed inside a hook shaft and having a hook oil supply mechanism for supplying oil to the hook in conjunction with a sewing machine main shaft, oil is supplied from the oil supply path to the outside of the hook shaft. It is easy to supply oil to the meshing part of the hook shaft gear and the drive gear by providing a discharge hole for letting out the oil and an oil core hung between the gear and the discharge hole of the hook drive mechanism. This makes it possible to reliably supply lubricating oil to the hook shaft gear.
