Abstract

The invention belongs to the technical field of sewing machines and particularly relates to a lubrication system of a sewing machine. A transmission chamber is arranged on the lower portion of a sewing machine shell, a feed lifting rock shaft drives a rotating hook shaft to rotate through a second transmission mechanism, an oil box is mounted on the lower portion of the transmission chamber, an oil storage cavity is arranged in the oil box which seals the lower end face of the transmission chamber, the second transmission mechanism is in gear transmission, a driving gear mounted on the feed lifting rock shaft meshes with a driven gear mounted on the rotating hook shaft, an oil storage tray is mounted in the transmission chamber and on the lower side of the driving gear, and the lower portion of the driving gear is immersed with oil fluid when a specific quantity of oil fluid is accumulated in the oil storage tray. The lubrication system of the sewing machine has the advantages that the oil fluid in the oil storage tray can be thrown out when the driving gear rotates at a high speed and sputtered on the inner walls of parts and components and the transmission chamber, so that lubrication oil is better in atomization effect in the transmission chamber, all the components can be lubricated effectively, and operating noise is reduced greatly.

Description

technical field [0001] The invention belongs to the technical field of sewing machines, in particular to a lubricating system of a sewing machine. Background technique [0002] There will always be noise during the working process of the sewing machine. As the use time of the sewing machine increases, the noise may increase. The reason is that the lubrication system design of the sewing machine is unreasonable. This kind of sound accompanying the operator for a long time will have a certain impact on his body. Therefore, the applicant has redesigned the lubricating system of the sewing machine. Contents of the invention [0003] The present invention provides a newly designed lubricating system for sewing machines aimed at the above problems. [0004] The purpose of the present invention is achieved like this: [0005] A lubricating system for a sewing machine. A transmission chamber is arranged at the lower part of the sewing machine housing, and a tooth lifting shaft,...
