Abstract
The invention provides a sewing machine and belongs to the technical field of sewing machines. The sewing machine comprises a lower plate, a lower shaft, a transmission shaft, an upper shaft, a rotating shuttle and a gear mechanism, the lower shaft, the transmission shaft, the upper shaft and the gear mechanism achieve linkage motion, the rotating shuttle is installed at the left end of the lower plate and is in linkage motion with the end of the lower shaft, the lower shaft is shorter than the transmission shaft, the gear mechanism is installed on the lower surface of the lower plate and is close to the end, where the rotating shuttle is located, of the lower plate, and the lower shaft is located between the rotating shuttle and the gear mechanism; the position, located over the gear mechanism, of the lower plate is provided with a maintenance window and a cover plate. A gear box is arranged in front, the lower shaft is comparatively short, and the rotating speed of the lower shaft is twice that of a driving shaft of the upper shaft, so that the lower shaft is shortened, transmission stability is high, and the rotating shuttle thread hooking stability is better. An upper cover of the gear box can be opened from the upper portion of a machine, so that maintenance, observation of the height of the oil level of the gear box, gear box oil refilling and other operation are conducted, and maintainability is good.
Description
Technical field
The invention belongs to sewing machine technique field, more particularly, it relates to a kind of Sewing machines of convenient for maintaining gear-box.
Background technology
Long-armed machine or template machine need larger sewing space, and head can do long, and current long-armed car or template machine all adopt the technology of common flat seam machine.Upper lower shaft gear is positioned at after baseplate of sewing machine, and power transmission shaft therefore lower shaft is long, and by change-speed gearing or synchronizing wheel, the rotating speed of lower shaft is the twice of upper axle rotating speed, and lower shaft external diameter compares, power transmission shaft is little, rotating shuttle therefore can be caused to hook line stabilization and decline; Machine uses in factory may relate to the maintenance of speed change gear, long-armed car or template machine weight is large, volume large, thus directly above Sewing machines maintenance wait to operate and be quite necessary.
There is following defect in prior art:
Because long-armed car or template machine change-speed gearing or synchronizing wheel are positioned at after baseplate of sewing machine, sewing machine head lower shaft is long, thinner; There is shortcoming:
1, lower shaft is long and thin and become the twice of upper axle rotating speed by its rotating speed of speed change, and therefore transmission stability is poor, and rotating shuttle hooks the stability relative mistake of line;
2, gear can only assemble or keep in repair below base plate;
Shortcoming: long-armed car or the general volume of template machine is large, weight is large, particularly the general head of template machine can not overturn, and maintenanceability is poor.
3, lower shaft is long and thin, and part processing is more difficult, easily goes out defective work.
Summary of the invention
For the deficiency that prior art exists, the object of the present invention is to provide and a kind ofly can improve the Sewing machines that rotating shuttle hooks the stability convenient for maintaining gear-box again of line.
For achieving the above object, the invention provides following technical scheme: a kind of Sewing machines, comprise lower plate, lower shaft, power transmission shaft, upper axle, rotating shuttle, gear mechanism, described lower shaft, power transmission shaft, upper axle and gear mechanism realize interlock, described rotating shuttle is arranged on the left end of lower plate and links with lower shaft end, lower shaft is shorter than power transmission shaft, and gear mechanism is arranged on the lower surface of lower plate and that end of close rotating shuttle, and lower shaft is between rotating shuttle and gear mechanism; Lower plate offers maintenance window and is provided with cover plate directly over gear mechanism.
As preferably, be connected for removable between described cover plate and the maintenance window of lower plate.
As preferably, the described removable bolt that is connected to connects or absorption type.
As preferably, described lower shaft length is less than 400mm.
As preferably, described gear mechanism is provided with drain pan, and drain pan is arranged in lower plate.
The invention has the beneficial effects as follows: a kind of Sewing machines of the present invention, gear-box is preposition, and lower shaft is shorter, and simultaneously because lower shaft rotating speed is the twice of upper axle driving shaft, the lower shaft like this transmission stability that shortens is high, and it is better that rotating shuttle hooks line stabilization; And lower shaft shortens, part difficulty of processing reduces.Can open gear-box upper cover above machine, carry out keeping in repair or observe gear case oil liquid level, add the operation of gear-box wet goods, maintenanceability is good.

Detailed description of the invention
See figures.1.and.2 and a kind of Sewing machines embodiment of the present invention is described further.In order to more outstanding innovative point of the present invention, the present invention only depicts partial view and part-structure, and all the other structures are the same with prior art.
A kind of Sewing machines of the present invention, comprise lower plate 1, lower shaft 2, power transmission shaft 7, upper axle 8, rotating shuttle 3, gear mechanism 4, described lower shaft 2, power transmission shaft 7, upper axle 8 and gear mechanism 4 realize interlock, described rotating shuttle 3 is arranged on the left end of lower plate 1 and links with lower shaft 2 end, lower shaft 2 is shorter than power transmission shaft 7, gear mechanism 4 is arranged on the lower surface of lower plate 1 and that end of close rotating shuttle 3, and lower shaft 2 is between rotating shuttle 3 and gear mechanism 4; Lower plate 1 offers maintenance window and is provided with cover plate 5 directly over gear mechanism 4.Be connected for removable between described cover plate 5 and the maintenance window of lower plate 1.The described removable bolt that is connected to connects or absorption type.Described lower shaft 2 length is less than 400mm.Described gear mechanism 4 is provided with drain pan 6, and drain pan 6 is arranged in lower plate 1.
A kind of Sewing machines of the present invention, gear-box is preposition, and lower shaft is shorter, and lower shaft 2 length is less than 400mm, is preferably 350mm, and simultaneously because lower shaft rotating speed is the twice of upper axle driving shaft, the lower shaft like this transmission stability that shortens is high, and it is better that rotating shuttle hooks line stabilization.Be connected for removable between cover plate 5 and the maintenance window of lower plate 1, the removable bolt that is connected to connects or absorption type.Gear mechanism 4 is provided with drain pan 6, and drain pan 6 is arranged in lower plate 1, can open gear-box upper cover above machine, and carry out keeping in repair or observe gear case oil liquid level, add the operation of gear-box wet goods, maintenanceability is good.
