Abstract
The utility model discloses a connecting structure of shafts, consisting of the two shafts; the end parts of the two shafts are respectively provided with a step structure; the directions of the two step structures are opposite to each other; the two step structures have excircle coaxiality of the shafts; and a hoop which is shorter along the axial direction and higher in external diameter strength is additionally arranged at the joint part and is provided with a screw. The connecting structure of the shafts is applicable to an embroidery machine.
Description
Technical field
The utility model relates to a kind of joining shaft, especially relates to a kind of connecting structure.
Background technique
Along with embroidery machine develops apart from direction towards large-scale, bull, microcephaly, a kind of axle connects reliable with axle, and it is the difficult problem that must solve that precision height, axial distance require short connecting mode.The technology that the axle that adopts on embroidery machine at present connects with axle is that the two ends of tack axle connect, and adopts the anchor ear parcel, with the connecting mode of screw-driving, the axle that this connecting mode connects is because conjunction plane is smooth, surface of contact is little, and in use loosening easily, working life is short.
Summary of the invention
The purpose of this utility model is at the existing shortcoming of above-mentioned joining shaft, provides a kind of connection firm, a kind of connecting structure of long service life.
In order to achieve the above object, the utility model is mainly realized by the following technical solutions.The utility model mainly is made up of two axles, is respectively equipped with ledge structure in the end of two axles, and the direction of two ledge structures is opposite, has an outer circles, add at seam crossing one axially shorter, the anchor ear that external diameter intensity is big, anchor ear is provided with screw.
The utility model compared with prior art has following tangible advantage.The shaft coupling mode that the utility model adopts is the mode that adds anchor ear with the ladder step, has solved the unstable shortcoming of traditional shaft coupling well.Because adopt and process the opposite step of direction respectively at the spindle nose place of shaft coupling, the cylindrical of axle was unison when step was combined together, pack tightly with anchor ear, the high pulling torque that axle is transmitted, by the effect of pillow block rank and anchor ear, reliable transmission under the less space of spacing.
The utility model is applicable to embroidery machine.
Following structure is closed the drawings and specific embodiments the utility model is described in further detail.
Description of drawings
Accompanying drawing is the utility model overall structure decomposing schematic representation.
Embodiment
As shown in the figure, the utility model mainly is made up of 1,6 on two axles, be provided with in the end of two axles 1,6 and be respectively equipped with ledge structure 4,5, the direction of two ledge structures 4,5 is opposite, has an outer circles, add at seam crossing one axially shorter, the anchor ear 2 that external diameter intensity is big, anchor ear 2 is provided with screw 3.
The utility model is applicable to embroidery machine.
