Description
Technical field
The utility model belongs to field of mechanical technique, relates to the shaft coupling of a kind of shaft coupling, particularly a kind of Sewing machines.
Background technology
Shaft coupling is that two axles (driving shaft and driven shaft) that are used for connecting in the different institutions make it common rotation to transmit the machine components of moment of torsion.At present, be used in the driven shaft Connection Block that the shaft coupling on the Sewing machines generally comprises the driving shaft Connection Block and is fixed together with the driving shaft Connection Block, driving shaft Connection Block and driven shaft Connection Block all adopt metal material to process.In order to eliminate the hard connection noise that transmission produced between the metal, between driving shaft Connection Block and driven shaft Connection Block, increase cushion pad.In concrete assembling, earlier with driven shaft Connection Block interference fit on cushion pad, again with the cushion pad interference fit on the driving shaft Connection Block, at last with the bearing cone place of driving shaft Connection Block interference fit to bearing.Because driving shaft Connection Block, cushion pad and driven shaft Connection Block three are three separate parts, the cooperation between them is the very few gap that all exists too much, and the cushion pad easy abrasion influences service life of shaft coupling, can not effectively reduce noise.In addition, when driving shaft Connection Block interference fit arrives the bearing cone place of bearing, if the magnitude of interference between the two is less, inconvenient installation; If the magnitude of interference between the two is bigger, both can occur again relatively rotating, and influence is normally used.
Summary of the invention
The purpose of the utility model is to have the problems referred to above to existing technology, has proposed a kind of shaft coupling of Sewing machines, and this shaft coupling has that use is not easy to wear, noise is little, the easy-to-install characteristics.

The shaft coupling of this Sewing machines is used for two axles are linked together, such as motor output shaft and machine spindle are linked together.When this shaft coupling is used for connecting motor output shaft and machine spindle; The bearing fitted shaft bearing of the shaft coupling of this Sewing machines is fixed on the casing place of Sewing machines; The connecting portion of bearing cone can be used for being connected mutually with motor output shaft or machine spindle, and the shaft coupling fuse that is arranged in the bearing cone mounting groove can be used for being connected mutually with machine spindle or motor output shaft; The machine operation rear output shaft just can drive the rotation of machine spindle through the shaft coupling of this Sewing machines like this, power is provided for the work of Sewing machines.Because the shaft coupling fuse is wrapped with and the integrated cushion pad of shaft coupling fuse; Mounting groove through cushion pad and bearing cone forms interference fit; Cushion pad is a rubber-like, therefore, is not easy to produce wearing and tearing between shaft coupling fuse and the bearing cone; The noise that the shaft coupling that has also reduced this Sewing machines produces when rotating has prolonged service life of the shaft coupling of this Sewing machines.In addition, the shaft coupling of this Sewing machines directly is used for linking to each other with axle through the connecting portion that bearing cone is outwards protruded, and has saved the step of former shaft coupling and bearing cone assembling, installs easier.
In the shaft coupling of above-mentioned Sewing machines, described cushion pad is a rubber blanket, and described rubber blanket is solidly fixed through the mode and the shaft coupling fuse of sulfuration.Mode through sulfuration is solidly fixed shaft coupling fuse and rubber blanket, makes not have the gap between the two, reduces wearing and tearing between the two; Simultaneously, between the two connectivity robustness is better.
In the shaft coupling of above-mentioned Sewing machines, has the connecting hole that is connected with above-mentioned mounting groove on the connecting portion of said bearing cone.
In the shaft coupling of above-mentioned Sewing machines, also offer the locating hole that runs through connecting portion on the hole wall of said connecting hole.
Machine spindle or motor output shaft are located in connecting hole, pass locating hole through screw again machine spindle or motor output shaft are fixed on the connecting portion.
In the shaft coupling of above-mentioned Sewing machines, said shaft coupling fuse has several key teeth with respect to shaft coupling mandrel body protrusion.Through such design, make in the mounting groove that is installed in bearing cone that the shaft coupling fuse can be more stable.
In the shaft coupling of above-mentioned Sewing machines, said shaft coupling fuse have one run through the shaft coupling mandrel body installing hole.
In the shaft coupling of above-mentioned Sewing machines, all offer the tightening hole of running through the key tooth and being connected on the key tooth of said shaft coupling fuse with above-mentioned installing hole.
Motor output shaft or machine spindle are located in the installing hole, and screw passes the tightening hole motor output shaft or machine spindle are fixed on the key tooth of shaft coupling fuse.
Compared with prior art, the utlity model has following advantage:
1, through outside the shaft coupling fuse, being fixed with rubber blanket, make the mounting groove of rubber blanket and bearing cone form interference fit, because the rubber blanket rubber-like makes to be not easy to produce wearing and tearing between shaft coupling fuse and the bearing cone, improve service life; The noise that the shaft coupling that has also reduced this Sewing machines produces when rotating.
2, the shaft coupling of this Sewing machines through with bearing cone outwards the connecting portion of protrusion directly be used for being connected with axle, saved the step that former shaft coupling and bearing cone assemble, install easylier, connect more stable.
