Abstract
The utility model discloses a transmission shaft connection structure. The transmission shaft connection structure comprises a first transmission shaft, a second transmission shaft and a lock sleeve, wherein the lock sleeve is connected with one adjacent ends of the first transmission shaft and the second transmission shaft in a sleeved mode. A key groove is formed in the connection position of the first transmission shaft and the second transmission shaft, and a connection key is correspondingly inserted into the key groove. By means of the transmission shaft connection structure, a long transmission shaft of a seam quilting machine can be divided into a plurality of short shafts, and all the short shafts are connected through transmission shaft connection mechanisms. Therefore, convenience is brought to production and assembly. If one headpiece goes wrong, corresponding short shafts are taken down, disassembly and assembly are easy, and maintenance is convenient. If parts of the transmission shafts are damaged, the damaged short shafts need to be replaced only. Therefore, maintenance costs are lowered.
Description
Technical field
The utility model relates to a kind of transmission shaft, especially a kind of transmission shaft connecting structure.
Background technique
At present, the pin shuttle drive part of general quilting machine (bull) all is to realize the two-part running of pin shuttle by the fixed pulley on one to two transmission shaft, the drawback of this structure is to have brought very large trouble to indivedual head section maintenances and maintenance, a head goes wrong and will dismantle a whole set of drive part, and relatively effort is installed after having changed component again.If transmission shaft partly damages, whole axle just needs to change, and has greatly increased so again cost.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of transmission shaft connecting structure, so that transmission shaft assembling-disassembling is convenient, maintenance cost is low.
In order to solve the problems of the technologies described above, the utility model transmission shaft connecting mechanism is one to be socketed in the lock sleeve on the outer circumferential face of the first transmission shaft and second driving shaft abutting end, described two transmission shaft bonds connect, in the flange that described lock sleeve comprises a sleeve and two described two conical rings of conical ring snaps in gap between sleeve and two transmission shafts from the two ends of sleeve respectively, and pass through bolt-locking with sleeve.
Described the first transmission shaft and second driving shaft two abutting ends are formed with respectively a breach accordingly, respectively be formed with a semi-circular recesses on the side end face of two described breach, each described semi-circular recesses only has an end to be connected with the outer circumferential face of the first transmission shaft or second driving shaft.
Described keyway is the blind cylindrical hole of two described semi-circular recesses splicings.
After adopting such structure, transmission shaft long on the quilting machine can be divided into a plurality of minor axises, by transmission shaft connecting mechanism each minor axis is coupled together again.So just give and produce and assemble and brought convenience, a head goes wrong and just takes off corresponding minor axis, both has been easy to dismounting, is convenient to again maintenance, damages if there is the part of transmission shaft, and the minor axis that only needs replacing to damage gets final product, and has reduced so again maintenance expenses.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is the schematic representation of the utility model transmission shaft connecting structure;
Fig. 2 is the schematic representation of the first transmission shaft in the utility model transmission shaft connecting structure;
Fig. 3 is the sectional view of connecting key in the utility model transmission shaft connecting structure;
Fig. 4 is the use phase diagram of the utility model transmission shaft connecting structure.
Embodiment
Referring to Fig. 1 to Fig. 4, the utility model transmission shaft connecting mechanism is one to be socketed in the lock sleeve 3 on the outer circumferential face of the first transmission shaft 1 and second driving shaft 2 abutting ends, described two transmission shaft bonds connect, in the flange that described lock sleeve 3 comprises a sleeve 31 and two conical ring 32 described two conical rings 32 snaps in gap between sleeve and two transmission shafts from the two ends of sleeve 31 respectively, and with sleeve 31 by bolt 33 lockings.
Described the first transmission shaft 1 is formed with respectively a breach 21 accordingly with 2 liang of abutting ends of second driving shaft, respectively be formed with a semi-circular recesses 22 on the side end face of two described breach 21, each described semi-circular recesses 22 only has an end to be connected with the outer circumferential face of the first transmission shaft 1 or second driving shaft 2.
Described keyway 4 is the blind cylindrical hole of two described semi-circular recesses 22 splicings.
Described connecting key 5 is a cylindrical keys, its upper-end surface and transmission shaft outer circumferential face are complementary, the lower end surface is a circular flat, and described connecting key 5 adapts with keyway 4 and connecting key 5 forms a complete outer peripheral surface with the joint that makes the first transmission shaft 1 with second driving shaft 2 cooperating of keyway 4.
After adopting such structure, transmission shaft long on the quilting machine can be divided into a plurality of minor axises, by transmission shaft connecting mechanism each minor axis is coupled together again.Realize rotating synchronously in order to make each minor axis that links together, joint between described two adjacent minor axises is formed with a keyway 4, guarantee the Synchronous Transmission of each section minor axis by a connecting key 5, meanwhile two abutting ends at two adjacent minor axises are socketed with a lock sleeve 3, connecting key 5 is fixed on 4 li in keyway under the effect of lock sleeve 3 sleeves 31 inwalls, the effect one of above-mentioned lock sleeve 3 is in order to guarantee that connecting key 5 can not break away from keyway 4 in rotation process, the 2nd, in order to guarantee the coaxality of each minor axis, make its stable drive.
Such structure is just given and is produced and assemble and brought convenience, and a head goes wrong and just takes off corresponding minor axis, both has been easy to dismounting, be convenient to again maintenance, part if there is transmission shaft is damaged, and only needs to change the minor axis that has damaged and gets final product, and has reduced so again maintenance expenses.
In sum, content of the present utility model is not limited in the above-described embodiment, and those skilled in the art can propose other embodiment within technological guidance's thought of the present utility model, but these embodiments are included within the scope of the present utility model.
