Abstract
The invention discloses a gear case of a sewing machine. The gear case is provided with a case body which is provided with a driven chamber for installing a driven gear. The driven chamber is provided with a cover plate. A driving chamber communicating with the driven chamber for installing a driving gear is arranged on one side face of the case body. The driving gear and the driven gear are meshed with each other. A driving shaft and a driven shaft are respectively arranged in the centers of the driving and driven gears. A positioning hole for installing the driven shaft is arranged in the center of the cover plate. A positioning pin is arranged above the cover plate and on the side face of the driven shaft. A threaded hole for installing a bolt is respectively arranged at four corresponding corners of the connecting face of the cover plate and the case body. According to the gear case of the sewing machine provided by the utility model, the gears are more reasonably connected, so that the gear case is convenient to install, detach and maintain and lower in cost.
Description
Technical field
The present invention relates to the Sewing machines field, relate in particular to a kind of Sewing machines gear-box.
Background technology
Sewing machines is to use one or more sewing thread, forms one or more stitchings, the machine that makes one or more layers sewing interweave or unite by a seam on sewing.The sewing function is made goods such as fabric such as cotton, fiber crops, silk, hair, artificial fibre and leather, plastics, paper, the stitching neat appearance of stitching out, smooth firm, and sewing velocity is fast, easy to use.Because the main skill of handling needles of Sewing machines realizes by cam, for the Sewing machines cam is turned round flexibly, cam-type on the Sewing machines is by gear drive, but structure more complicated between the existing Sewing machines cam driving gear, installing/dismounting is more loaded down with trivial details, be not easy to maintenance and maintenance, and fragile.
Summary of the invention
Technical problem to be solved by this invention is that a kind of Sewing machines gear-box that is used to drive the Sewing machines cam rotation is provided.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions: a kind of Sewing machines gear-box, has casing, be provided with the driven chamber that is used to install driven gear above the described casing, driven chamber is provided with cover plate, casing one side is provided with described driven chamber and connects the active chamber that is used to install driving gear, described driving gear and driven gear are meshing with each other, driving gear and driven gear center are respectively arranged with driving shaft and driven shaft, and the cover plate center is provided with the locating hole that is used to install driven shaft.
Preferably, described driven shaft side is positioned at the cover plate top and is provided with alignment pin.
Preferably, four jiaos of described cover plate and casing joint face correspondence respectively are provided with a screwed hole that is used for construction bolt.
Compared with prior art, usefulness of the present invention is: this Sewing machines gear-box makes the connection between the gear more reasonable, is convenient to installation and removal, convenient for maintaining and maintenance, and cost is lower.
Description of drawings:
The present invention is further described below in conjunction with accompanying drawing.
Fig. 1 is a kind of Sewing machines gear box structure of the present invention schematic diagram.
Among the figure: 1, casing; 2, driving gear; 3, driven chamber; 4, screwed hole; 5, locating hole; 6, cover plate; 7, driving gear; 8, active chamber.
The specific embodiment:
Describe the present invention below in conjunction with the drawings and the specific embodiments:
A kind of Sewing machines gear-box shown in Figure 1, has casing 1, be provided with the driven chamber 3 that is used to install driven gear 7 above the described casing 1, driven chamber 3 is provided with cover plate 6, casing 1 one sides are provided with described driven chamber 3 and connect the active chamber 8 that is used to install driving gear 2, described driving gear 2 is meshing with each other with driven gear 7, and driving gear 2 and driven gear 7 centers are respectively arranged with driving shaft 11 and driven shaft 9, and cover plate 6 centers are provided with the locating hole 5 that is used to install driven shaft 9; Described driven shaft 9 sides are positioned at cover plate 6 tops and are provided with alignment pin 10; Be used to locate the cam that is arranged on the driven shaft 9; Fixing for the ease of between cover plate 6 and the casing 1, described cover plate 6 and casing 1 joint face correspondence four jiaos respectively are provided with a screwed hole 4 that is used for construction bolt.
During work, motor drives driving gear 2 by driving shaft 11 and rotates, driving gear 2 and driven gear 7 engagements, thereby driving driven gear 7 changes, because driven gear 7 fixes with driven shaft 9, rotate thereby drive driven shaft 9, on the driven shaft 9 cam is installed, cam is spacing by the alignment pin 10 on the driven shaft 9, thereby drives cam rotation.
This Sewing machines gear-box makes the connection between the gear more reasonable, is convenient to installation and removal, convenient for maintaining and maintenance, and cost is lower.
It is emphasized that: above only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment did.
