Abstract

The utility model relates to a sewing machine, including hypoplastron, lower, transmission shaft, upper shaft, rotating shuttle, gear, lower, transmission shaft, upper shaft and gear realize the linkage, the rotating shuttle install the left end of hypoplastron and with axle head portion linkage down, lower weak point in transmission shaft, gear install the lower surface of hypoplastron just near that end of rotating shuttle, lower position of axle is between rotating shuttle and gear, the hypoplastron has been seted up the maintenance window and has been equipped with the apron directly over gear. The gear box is leading, and lower axial ratio is shorter, simultaneously because the speed of spindle is the twice of upper shaft drive shaft down, so lower shortens the transmission stability height all, and it is better that the rotating shuttle colludes line stabilization nature. Can follow and open the gear box upper cover above the machine, maintain or observe gear box oil liquid level, add operation such as gear box oil, maintainability is good. The utility model belongs to the technical field of sewing machine.

Description

A kind of Sewing machines

Technical field

The utility model belongs to sewing machine technique field, and 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.

Utility model content

For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of Sewing machines that can improve stability that rotating shuttle hooks line convenient for maintaining gear-box again.

For achieving the above object, the utility model 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 beneficial effects of the utility model are: a kind of Sewing machines of the utility model, and 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 utility model is described further.In order to more outstanding innovative point of the present utility model, the utility model 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 utility model, 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 utility model, 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.
