AI Technical Summary
Technical Problem
The shuttle structure of existing sewing machines cannot be effectively lubricated, resulting in severe transmission wear, short service life, and high noise.
Method used
A sealed, fully lubricated shuttle transmission structure is designed, in which the driven gear of the lower shaft, the bevel gear of the lower shaft, the eccentric device and the connecting rod are set in the lower oil tank of the frame. The eccentric device drives the bevel gear of the lower shaft to swing back and forth, thus achieving full lubrication.
Benefits of technology
It significantly reduces transmission wear, extends the service life of the transmission structure, and reduces noise.

Abstract
The utility model discloses a sealed full lubrication swing shuttle transmission structure, it includes: the lower shaft driven gear of installation in the lower main shaft, the lower shaft bevel gear of setting in the lower shaft driven gear side and mutually meshed, the lower swing axle of parallel setting in the lower main shaft side and be used for supporting the lower shaft bevel gear, the eccentric device of setting in the lower shaft bevel gear side and through transmission belt pulley subassembly with main shaft module connection and the connecting rod of connecting eccentric device and the lower shaft bevel gear, wherein, the lower shaft driven gear, the lower shaft bevel gear, eccentric device and connecting rod all are located in the oil tank of frame lower. Adopt eccentric device through connecting rod and promote the lower shaft bevel gear swing, then through the lower shaft driven gear and drive the lower main shaft reciprocating rotation, thereby reduce the motion stroke, thereby can set up the lower shaft driven gear, the lower shaft bevel gear, eccentric device and connecting rod in the oil tank of frame lower, make transmission structure can be soaked in lubricating oil and realize full lubrication, greatly reduce transmission wear, promote transmission structure service life, can reduce the noise.
