Cycloid rotor pump of sewing machine

Abstract

The invention discloses a cycloid rotor pump of a sewing machine. The cycloid rotor pump comprises a base and is characterized by further comprising a pump body, an inner rotor and an outer rotor, wherein the base is round and is hinged to the pump body through screws, the outer rotor is arranged on the pump body and can move in the pump body freely, inner teeth are arranged on the inner side of the outer rotor, outer teeth are arranged on the outer side of the inner rotor, the inner teeth and the outer teeth can be partially meshed, and the inner teeth is one less than the outer teeth. The cycloid rotor pump of the sewing machine solves problems that quick and effective lubrication cannot be realized, usage of sewing machines is affected, parts of the sewing machines are abraded quickly and service lives of the sewing machines are greatly shortened due to the fact that the sewing machines suck and discharge lubrication oil in a very troublesome manner in the prior art, is simple in structure, convenient to use and lower in noise and can suck and discharge the oil relatively fully, and oil flows stably.

Description

technical field [0001] The invention relates to a cycloid rotor pump, in particular to a cycloid rotor pump for a sewing machine. Background technique [0002] A sewing machine is a machine that uses one or more sewing threads to form one or more stitches on the sewing material to interweave or sew one or more layers of sewing material. The sewing machine can sew cotton, hemp, silk, wool, artificial fiber such as fabrics and leather, plastic , paper and other products, the stitches are neat and beautiful, flat and firm, with fast sewing speed and easy use. At present, the suction and discharge of lubricating oil in the sewing machine is very troublesome, and fast and effective lubrication cannot be achieved, which affects the use of the sewing machine, also causes rapid wear of various parts thereof, and greatly reduces the service life of the sewing machine. Contents of the invention [0003] In order to solve the problem that the suction and discharge of lubricating ...
