Abstract
The utility model discloses a there is not oily rotating shuttle, include the shuttle race and install the shuttle frame on the shuttle race that the shuttle frame outside sets up wire board and yue quan, sets up the slot on the shuttle race, sets up the rib of scarf joint on the slot on the shuttle frame, sets up the air guide hole on the slot. It is eliminated lubricating oil and pollutes the phenomenon through getting rid of the oiling structure, reduces substantially the friction simultaneously, the noise reduction to improve product life.
Description
Technical field
The utility model relates to a kind of Sewing machines accessory, especially relates to a kind of without oily rotating shuttle.
Background technology
High speed rotating shuttle, as the critical component of industrial sewing machine, is seen as the heart of Sewing machines usually.Rotating shuttle is mainly made up of shuttle frame and shuttle race two parts, together with cooperatively interacting be installed in by shuttle frame muscle and shuttle race groove, this structure is in the process of High Rotation Speed, by generation wearing and tearing and calcination between shuttle frame muscle and shuttle race groove, so prior art usually adopts the mode arranging oil guide groove oil injecting lubricating, to reduce friction, reduce noise, increase the service life.But the complex structural designs of oil injecting lubricating, the product phenomenon that lubricant pollution is made is inevitable.
Utility model content
The utility model is for the deficiencies in the prior art, and technical problem to be solved is to provide a kind of without oily rotating shuttle, and it, by removing oil injection structure, eliminates lubricant pollution phenomenon, significantly reduces friction simultaneously, reduces noise, thus improves product service life.
The utility model makes above-mentioned technical problem be solved by the following technical programs.
A kind of without oily rotating shuttle, comprise shuttle race and be installed in the shuttle frame on shuttle race, shuttle frame arranged outside wire guide plate and Yue Quan, shuttle race arranges groove, shuttle frame is arranged the rib of interlocking on groove, groove arranges gas port.In the structure shown here, by arranging gas port at rib place chimeric with groove, when making High Rotation Speed, air forms air buffer via gas port at chimeric position, air buffer well prevents rib and groove mutually to wear and tear the noise greatly reducing simultaneously and wear and tear and bring, this structure not only extends service life, and avoids the phenomenon of lubricant pollution quilt.
As preferably, the surface of shuttle race is provided with tower screw.
As preferably, the moon circle surface on be provided with moon circle screw.
As preferably, the surface of wire guide plate is provided with wire guide plate screw.
As preferably, the outside of shuttle race is arranged with shell.
As preferably, groove and rib are equipped with as some groups and in circumferential uniform setting.
The beneficial effects of the utility model:
1. remove oil filling mechanism, structure is simplified greatly, reduce and use component, reduce costs, and eliminate the phenomenon of lubricant pollution product.
2. import air formation air buffer by gas port to reduce wear, reduce noise, significantly extend the service life of product.
3. it is convenient to safeguard, safe and reliable, long-term operation is not fragile, is applicable to large batch of production application.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the partial enlargement sectional structure schematic diagram of gas port of the present utility model.
In figure: 1-shuttle race, 2-shuttle frame, 3-wire guide plate, 4-month circle, 5-groove, 6-rib, 7-gas port, 8-tower screw, 9-month circle screw, 10-wire guide plate screw.
Detailed description of the invention
Also by reference to the accompanying drawings the utility model is described in detail below by embodiment.
The utility model as shown in Fig. 1 Fig. 2 is a kind of without oily rotating shuttle, the shuttle frame 2 comprising shuttle race 1 and be installed on shuttle race 1, shuttle frame 2 arranged outside wire guide plate 3 and the moon circle 4, shuttle race 1 is arranged groove 5, shuttle frame 2 is arranged the rib 6 of interlocking on groove 5.Groove 5 coordinates with rib 6 can be set to some groups and in circumferential uniform setting.Shuttle race 1 is in the process of High Rotation Speed, generation rubs with the fitting portion of groove 5 by rib 6, not only the large and friction scaling loss of noise can affect the service life of product, therefore, as shown in Figure 2, the utility model changes oil filling mechanism in the past, by arranging gas port 7 on groove 5, when making High Rotation Speed, air forms air buffer via gas port 7 at chimeric position, air buffer well prevents the mutual wearing and tearing of rib 6 and groove 5 to greatly reduce the noise wearing and tearing and bring simultaneously, this structure to prolong service life, and avoid the phenomenon of lubricant pollution quilt.In order to reduce production cost, shuttle frame 2 can adopt metal material, also can select the naval stores that coefficient of friction is little.The outside of shuttle race 1 can sheathed shell.The surface of shuttle race 1 arranges tower screw 8, the moon circle 4 surface on moon circle screw 9 is set, for fixing shuttle race 1 and the moon circle 4.The surface of wire guide plate 3 is arranged wire guide plate screw 10 for fixing cord plate 3.
The utility model is not limited to above-described embodiment, the embodiment of other malformation that equivalence is replaced in the middle of the known technology that the resemblance of shuttle race and shuttle frame and syndeton each other also can adopt those skilled in the art to obtain or prior art, as long as belong to technical conceive of the present utility model or spirit, by the chimeric groove between shuttle race and shuttle frame arranges gas port, realize reducing friction to form air buffer by gas port when High Rotation Speed, reduce noise, the embodiment eliminated for the purpose of oil pollution phenomenon all drops in protection domain of the present utility model.
