Abstract
The utility model relates to a main shaft sleeve of a flat seaming machine, belonging to parts of a sewing machine. The scheme of the utility model is as follows: the inner wall of the main shaft sleeve of the flat seaming machine is manufactured with a spiral oil groove; the cylinder wall is manufactured with an oil inlet hole radially; the inner wall at the right end of the shaft sleeve is manufactured with a groove to form an oil return groove which is connected with the oil inlet hole. The outer wall of the shaft sleeve is manufactured with a strip groove which is communicated with the oil inlet hole; and the axial length of the strip groove is larger than the diameter of the oil inlet hole. The main shaft sleeve has the advantages that due to the adoption of the shaft sleeve with the structure, the redundant lubricating oil flows out of the right side of the shaft sleeve and enters an oil disc, thus reducing the oil supplying amount of the position of a guide rail of a tooth frame of a machine head, and further avoiding that the sewing materials is polluted by the lubricating oil due to the excessive oil leakage of feeding teeth ; and the outer wall of the shaft sleeve is manufactured with a long groove, thus being convenient to install the shaft sleeve.
Description
Technical field:
The utility model relates to the main shaft sleeve of the part of Sewing machines, particularly flat seaming machine.
Background technology:
The main shaft sleeve inwall of flat seaming machine is shaped on helical oil groove, and barrel radially is shaped on fuel feed hole, and this fuel feed hole links to each other with the casing oil duct; The sleeve lining left end is shaped on axial notch and forms oil-recovery tank, and this oil-recovery tank links to each other with fuel feed hole.Main shaft sleeve is assemblied in the flat seaming machine casing, and the left side is a Flat Seaming Machine Head, and parts such as retainer guide rail are equipped with in below, casing left side.During flat seaming machine work, lubricating oil enters sleeve lining from the oil duct of casing through fuel feed hole, overflows parts such as supplying with the retainer guide rail left by helical oil groove again; Unnecessary lubricating oil flows back in the food tray of bottom by the oil-recovery tank of axle sleeve left end, in reflux course, parts of lubricating oil flows to the parts such as retainer guide rail of below, causes part fuel delivery such as retainer guide rail excessive, cause feeding tooth oil impregnate easily, thereby cause sewing to pollute.
Summary of the invention:
The purpose of this utility model provides a kind of simple structure and can improve the flat seaming machine main shaft sleeve of principal axis lubrication environment.
Scheme of the present utility model is: the inwall of flat seaming machine main shaft sleeve is shaped on helical oil groove, and barrel radially is shaped on fuel feed hole, and axle sleeve right-hand member inwall is shaped on groove and forms oil-recovery tank, and oil-recovery tank links to each other with fuel feed hole.
The axle sleeve outer wall is shaped on rectangular groove, and this rectangular groove communicates with fuel feed hole, rectangular fluted shaft to length greater than the fuel feed hole diameter.
The utility model has the advantages that: adopt the axle sleeve of said structure, unnecessary lubricating oil flows out from the axle sleeve right side and enters food tray, has reduced the fuel delivery of head retainer guide rail position, thereby has avoided too much feeding tooth oil impregnate to cause the lubricant pollution sewing; The axle sleeve outer wall is shaped on elongated slot, makes things convenient for axle sleeve to install.
Description of drawings:
Fig. 1 is the utility model sectional arrangement drawing.
Fig. 2 is a front view of the present utility model.
Fig. 3 is a right view of the present utility model.
The specific embodiment:
Referring to figs. 1 through Fig. 3, axle sleeve 1 is assemblied in the casing 2, and casing 2 is provided with vertical oil duct b, and the left side that present embodiment is set casing 2 is a head.The inwall of axle sleeve 1 is shaped on helical oil groove c, and barrel radially is shaped on fuel feed hole a, and the right-hand member inwall is shaped on groove, and the afterbody of this groove links to each other with fuel feed hole a, forms oil-recovery tank d.Axle sleeve 1 outer wall system elongated slot e, elongated slot e links to each other with fuel feed hole a, and after axle sleeve 1 assembling, oil duct b, elongated slot e and fuel feed hole a communicate.All greater than the diameter of fuel feed hole a and oil duct b, axle sleeve 1 axial installation site is easy to adjust, guarantees that oil circuit communicates for rectangular groove e axial length.During flat seaming machine work, lubricating oil enters into axle sleeve 1 inwall by oil duct b on the casing 2 and the fuel feed hole a on the axle sleeve 1, a part of lubricating oil is seeped into the left side of casing 2 by helical oil groove c, supply with the lubrication needs of parts such as retainer guide rail, unnecessary lubricating oil then flows directly in the food tray by the right side that oil-recovery tank d gets back to casing 2, reduce the fuel delivery of head retainer guide rail position, thereby avoided too much fuel delivery to cause the lubricant pollution sewing.
