Abstract
The invention relates to a transmission mechanism of a sewing machine, in particular to a transmission mechanism of a semi-rotation rotating shuttle sewing machine. The transmission mechanism comprises a synchronous belt gear which is arranged in an upper machine shell and connected with a motor transmission shaft, the synchronous belt gear is connected with a synchronous wheel arranged in a lower machine shell, a synchronous wheel shaft is provided with an eccentric wheel connected with a swinging gear by a driving connection rod, the swinging gear is connected with a rotating shuttle driving gear arranged on a lower shaft, and the eccentric wheel, the driving connection rod, the swinging gear and the rotating shuttle driving gear are arranged in a sealed oil tank. The transmission mechanism has the advantages of good lubrication and heat dissipation effect, low cost and long service life.
Description
Technical field
The present invention relates to a kind of Sewing machines transmission mechanism, be specifically related to a kind of transmission mechanism of half spinning rotating shuttle sewing machine.
Background technology
Existing transmission mechanism of half spinning rotating shuttle sewing machine is that the drive link on the lower casing directly is connected going up on the axle of upper casing, and its forms of motion is for moving up and down, and this structure causes drive link long; It is overweight to conduct oneself with dignity; Also can cause eccentric wheel excessive, when rotating speed reached for 2700 commentaries on classics/times when above, because drive link and eccentric wheel and to put the friction of tie point of tooth excessive; Temperature rise is too high, makes transmission speed to increase again.Therefore, need regularly add lubricating oil at the tie point of drive link and eccentric wheel and pendulum tooth and reduce the mill sassafras,, avoid temperature rise too high to reduce resistance.But; Because eccentric wheel, drive link, pendulum tooth, rotating shuttle driven wheel all expose in upper and lower enclosure and turn round, when regularly after lubricating oil is added in the junction, under the high speed rotation of machine; Lubricating oil is prone to dished out; Cause the waste of lubricating oil and the pollution of environment, also make maintenance cost increase, cost improves.As apply oil not for a long time, can make that again the friction of tie point of drive link and eccentric wheel and pendulum tooth is excessive, temperature rise is too high, influences the service life of machine.
Summary of the invention
The objective of the invention is to defective, provide a kind of lubricated and good heat dissipation effect, cost low, and can prolong the machine transmission mechanism of half spinning rotating shuttle sewing machine in service life to existing Sewing machines transmission mechanism.
Technical scheme of the present invention is following: a kind of transmission mechanism of half spinning rotating shuttle sewing machine; Comprise the synchronous band gear that is connected with motor transmission shaft that is located in the upper casing; Synchronously the band gear is connected with synchronizing wheel in being located at lower casing through synchronous band, and wheel shaft is provided with eccentric wheel synchronously, and eccentric wheel passes through drive link and puts tooth and link to each other; The pendulum tooth is connected with rotating shuttle driven wheel on being located at lower shaft, and described eccentric wheel, drive link, pendulum tooth, rotating shuttle driven wheel are arranged in the fuel tank of sealing.
Aforesaid transmission mechanism of half spinning rotating shuttle sewing machine wherein, is provided with lubricating oil in the leakproof fuel cell, eccentric wheel, drive link, pendulum tooth, rotating shuttle driven wheel are immersed in the lubricating oil.
Aforesaid transmission mechanism of half spinning rotating shuttle sewing machine wherein, is provided with fin in the outer lower portion of leakproof fuel cell.
Beneficial effect of the present invention is following: owing to eccentric wheel, drive link, pendulum tooth, rotating shuttle driven wheel all seal and be located in the fuel tank; The friction point of drive link, eccentric wheel, pendulum tooth is fully lubricated, thereby make the sassafras that rubs bring resistance problem excessive and that temperature rise is too high to be resolved.Because the fuel tank in the lower body is hermetic, thereby makes the lubricating oil long preservation in fuel tank, can avoid because the lubricating oil that the machine high-speed rotation is caused is dished out in a large number; Simultaneously; Because eccentric wheel, drive link, pendulum tooth, rotating shuttle driven wheel are arranged in the hermetically sealed fuel tank of lower casing, the sassafras face that rubs is lubricated comprehensively, and the sassafras noise that rubs of transmission mechanism is reduced when making the mechanical high-speed running; Owing to fully lubricated, also make transmission speed significantly improve.In addition, maintenance cost of the present invention reduces significantly, obviously obtains service life prolonging, and the entreprise cost input reduces, and can play a role aspect the environment improving.The set fuel tank sealed heat-dissipating sheet in fuel tank bottom can be alleviated the too high problem of temperature in the fuel tank that causes because of running up of drive mechanism in the course of work.

The specific embodiment
Below in conjunction with accompanying drawing the present invention is carried out detailed description.
Like Fig. 1, Fig. 2, shown in Figure 3; Transmission mechanism of half spinning rotating shuttle sewing machine comprises and is located at the synchronous band gear 2 that the power transmission shafts with motor 1 in the upper casing 3 are connected; Synchronously band gear 2 through synchronously with 4 be located at lower casing 7 interior synchronizing wheels 6 and be connected; Wheel shaft is provided with eccentric wheel 9 synchronously; Eccentric wheel 9 links to each other with pendulum tooth 11 through drive link 10, puts tooth 11 and is connected with rotating shuttle driven wheel 5 on being located at lower shaft 13, described eccentric wheel 9, drive link 10, put tooth 11, rotating shuttle driven wheel 5 is arranged in the fuel tank 8 of sealing.Be provided with lubricating oil in the leakproof fuel cell 8, eccentric wheel 9, drive link 10, pendulum tooth 11, rotating shuttle driven wheel 5 are immersed in the lubricating oil.Outer lower portion at leakproof fuel cell 8 is provided with fin 12.
The course of work of above-mentioned transmission mechanism is following: the motor 1 on the upper casing 3 drives the synchronous band gear 2 that is located on the axle; Band gear 2 drives and is with 4 synchronously synchronously; Synchronously with the synchronizing wheel 6 of an end on the 4 synchronous wheel shafts that drive in the lower casings 7; Synchronizing wheels 6 in the lower casing 7 drive with being located at the other end on the synchronous wheel shaft and being positioned at the eccentric wheel 9 of leakproof fuel cell 8; Eccentric wheel 9 links to each other with pendulum tooth 11 through drive link 10, and pendulum tooth 11 drives lower shaft through the rotating shuttle driven wheel 5 that is located on the lower shaft 13, thereby accomplishes the half spinning rotating shuttle transmission process.
