Description

A kind of electronic driving main shaft of directly driving Sewing machines

Technical field

The utility model relates to a kind of electronic driving main shaft of directly driving Sewing machines.

Background technology

At present the mode of the motorized motions main shaft of Sewing machines mainly is divided into two kinds: a kind ofly give last spool by the belt wheel with transmission of power for motor, another kind of mode is a direct drive sewing machine, and promptly motor is by intermeshing shaft joint transferring power.Because of the former noise, vibration are big, the power consumption height, external form is not attractive in appearance, and direct-drive motor is significantly improved with respect to these problems, enjoys people's welcome.Yet existing most of direct drive sewing machine back space is bigger, and the structure assembling is complicated, and easy to wear, noise is big, unstable properties.Therefore a kind of assembling of invention design is simple, and cost is little, and noise is little, and the Sewing machines driving main shaft mechanism of stable performance necessitates.

The utility model content

The purpose of this utility model provides a kind of electronic driving main shaft of directly driving Sewing machines, and is bigger to overcome the existing product back space, and the structure assembling is complicated, and easy to wear, noise is big, the deficiency of unstable properties.

The purpose of this utility model is to be achieved through the following technical solutions:

A kind of electronic driving main shaft of directly driving Sewing machines, comprise axle, motor and connector I, II, described upward axle is a long column shape, last axle is provided with the hollow shaft of screw hole and end perforation, the top that last shaft hollow axle connects is plugged the shafting oil amount by crank oil mass restriction felt cover and is regulated pin, the described shafting oil amount that goes up is regulated pin and is fitted and go up the shafting oil amount and regulate pin O type snare and connect crank fuel-flow control pin, and another top of last is meshed with connector II; The end outside socket needle bar crank assembly that last shaft hollow axle connects links to each other, and described needle bar crank assembly comprises needle bar crank, and needle bar crank is fixed in by screw and is interspersed in interior going up on the axle; Described needle bar crank assembly links to each other with last axle bottom bracket axle by being socketed on the outer axle front shaft sleeve of going up of axle, the described axle bottom bracket axle of going up is fixed on the axle by screw, the described axle bottom bracket axle of going up links to each other with the feeding offset assembly by last shaft retaining ring assembly, described feeding eccentric wheel assembly comprises the feeding eccentric wheel and lifts tooth pitman shaft back-up ring, the feeding eccentric wheel is fixed in by screw and is interspersed in interior going up on the axle, described feeding eccentric wheel links to each other with bearing by feeding eccentric shaft cover plate sidewall, and bearing links to each other with motor by last shafting oil envelope; Described motor links to each other with connector I by the axle of going up in hollow shaft, and connector I links to each other with connector II by connector damping rubber circle, and described connector II die casting is on handwheel.

The beneficial effects of the utility model are: the design of adopting motor directly to link to each other with shaft joint with last axle, connect simply, and be convenient to installation, reduced cost, reduced noise, not easy to wear, and improved the overall performance of machine.
