Abstract
The utility model relates to sewing machine technique field, particularly relate to a kind of Sewing machines gear-box, it has the casing being made up of gear block and gear box plates, in casing, be fixed with transmission mechanism, this transmission mechanism comprises Timing Belt, be located at the driving wheel of Timing Belt lower inside, be located at Timing Belt both upper ends thereof inner side driven pulley, be located at the gear of driven pulley on gear box plates one end face and be located at the regulating wheel in outside, Timing Belt middle part, the motor that is connected on said gear boxboard, the axle core of this motor runs through gear box plates to box house and is fixedly connected with driving wheel.The utility model adopts the motor that is connected on gear-box, connects the mode of driving wheel by the axle core of motor, realizes the power output efficiency that improves Sewing machines gear-box; The inapplicable spline of the utility model structure, makes gear-box mechanism compacter, and the usage space of Sewing machines inside is larger by contrast, has the effect that reduces cost of manufacture.
Description
Technical field
The utility model relates to sewing machine technique field, particularly relates to a kind of Sewing machines gear-box.
Background technology
Sewing machines gear-box in the past, as shown in Figure 1, have: on driving wheel (4), a spline is set, driving wheel (4) is arranged to the groove matching with spline-shaped by embodiment in the past, and spline is communicated with motor, and driving wheel (4) drives outputting power by spline, this spline is set, and there are the following problems: the one,, because the power of gear-box is transferred on driving wheel indirectly by spline, mechanical energy is loss to some extent, causes the power of gear-box to reduce; The 2nd,, can distortion after spline is of a specified duration between in use, again lose at power output facet; The 3rd,, the cost of manufacture of spline and maintenance cost, add lubricant often.Not only had that to reduce costs but also can improve Sewing machines performance be the technical problem that current Sewing machines gear-box market demand solves.
Utility model content
The technical problems to be solved in the utility model is to propose a kind of Sewing machines gear-box that has reducing costs, improves Sewing machines performance.
For solving the problems of the technologies described above, the utility model adopts following scheme:
A kind of Sewing machines gear-box, there is the casing being formed by gear block and gear box plates, in casing, be fixed with transmission mechanism, this transmission mechanism comprises Timing Belt, be located at the driving wheel of Timing Belt lower inside, be located at Timing Belt both upper ends thereof inner side driven pulley, be located at the gear of driven pulley on gear box plates one end face and be located at the regulating wheel in outside, Timing Belt middle part, the motor that is connected on said gear boxboard, the axle core of this motor runs through gear box plates to box house and is fixedly connected with driving wheel.
Above-mentioned gear block is fixedly connected with by screw rod with gear box plates.
Above-mentioned gear box plates is provided with two chutes, and these two chutes are symmetrically distributed in gear box plates with gear box plates center line.
The beneficial effects of the utility model are:
1. the utility model adopts the motor that is connected on gear-box, connects the mode of driving wheel by the axle core of motor, realizes the power output efficiency that improves Sewing machines gear-box;
2. the inapplicable spline of the utility model structure, makes gear-box mechanism compacter, and the usage space of Sewing machines inside is larger by contrast, has the effect that reduces cost of manufacture.
Brief description of the drawings
Fig. 1 is the explosive view of Sewing machines gear-box in embodiment.
1, gear block; 2, gear box plates; 21, chute; 3, Timing Belt; 4, driving wheel; 5, driven pulley; 6, gear; 7, regulating wheel; 8, motor.
Detailed description of the invention
Be below specific embodiment of the utility model by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
Embodiment, as shown in Figure 1: a kind of Sewing machines gear-box, there is the casing being formed by gear block 1 and gear box plates 2, in casing, be fixed with transmission mechanism, this transmission mechanism comprises Timing Belt 3, be located at the driving wheel 4 of Timing Belt 3 lower inside, be located at the driven pulley 5 of Timing Belt 3 both upper ends thereof inner sides, be located at the gear 6 of driven pulley 5 on gear box plates 2 one end faces and the regulating wheel 7 of being located at Timing Belt 3 outsides, middle parts, a motor 8 is connected on said gear boxboard 2, the axle core of this motor 8 runs through gear box plates 2 to box house and is fixedly connected with driving wheel 4, set motor 8 in the present embodiment, directly connect the mode of driving wheel 4 by the axle core of motor 8, make in power output procedure loss minimum, this structure setting has the effect that improves Sewing machines gear-box power output efficiency.
Gear block 1 is fixedly connected with by screw rod with gear box plates 2, and it is easy to maintenance that this connected mode is conducive to the dismounting of gear-box.
Gear box plates 2 is provided with two chutes 21, and these two chutes 21 are symmetrically distributed in gear box plates 2 with gear box plates center line, and this chute 21 has the effect of fixed tensioning wheel 7, and chute 21 has the degree of being close to that regulates regulating wheel 7 and Timing Belt 3 simultaneously.
The foregoing is only preferred embodiment mode of the present utility model; the scope that can not limit with this utility model protection, the variation of any unsubstantiality that those skilled in the art does on basis of the present utility model and replacement all belong to the utility model scope required for protection.
