Abstract
The utility model discloses a conjugate cam transmission structure, which comprises a transmission shaft and a conjugate cam. A keyway is arranged on the transmission shaft which is integrally formed with the conjugate cam by normal forging, and the conjugate cam can be fixed on the transmission shaft by means of interference fit. The peak or the nadir of the conjugate cam is positioned on the symmetric center plane of the keyway of the transmission shaft. The conjugate and the transmission shaft cannot loosen in transmission process, and the conjugate cam transmission structure is stable and reliable in transmission, high in transmission precision, few in processing procedures, low in production cost and especially suitable for popularization and application to warp knitting machines.
Description
Technical field
The utility model relates to a kind of mechanical transmission structure, particularly relates to a kind of conjugate cam drive mechanism that is used for textile industry.
Background technique
It is reliable and stable that the conjugate cam transmission has transmission, and motion accurately and can adapt to many premium properties such as the requirement that runs up, thereby in textile industry, is especially obtaining extensive use through the volume industry.But, at present because conjugate cam adopts the Hough mode to be locked on the transmission shaft in assembly process usually, must use special tool when mounted and adopt complicated technology to guarantee assembly precision so on the one hand, on the other hand when running up, loosening phenomenon often takes place in Hough, so that the locking of conjugate cam and transmission shaft is unreliable, thereby causes fabric quality to descend, even causes the mechanical deterioration accident.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of in transmission process, and loosening phenomenon can not take place between conjugate cam and the transmission shaft, thereby guarantees the conjugate cam drive mechanism of transmission accuracy.
For solving the problems of the technologies described above, the utility model adopts so a kind of conjugate cam drive mechanism, comprises transmission shaft and conjugate cam, offers keyway on the described transmission shaft, and described transmission shaft and described conjugate cam are a single piece.
Described conjugate cam can be fastened on the described transmission shaft by interference fit, thereby makes both constitute a single piece.
Described transmission shaft and described conjugate cam also can be processed by forging, thereby become a single piece.
After adopting such structure, because transmission shaft and conjugate cam are a single piece structure, the utility model preferably constitutes a single piece by forging processing or interference fit with both, therefore, in transmission process, loosening phenomenon can not take place between conjugate cam and the transmission shaft, the transmission accuracy height, and omitted the assembly process of very complicated between the two, thus saved the production time, reduced cost of production.
As a kind of improvement of the present utility model, the peak of described conjugate cam or minimum point are positioned on the symmetry center face of keyway on the described transmission shaft.Adopt such structure, the symmetry center face of keyway is added the locating basis face in man-hour as cam, help improving the machining accuracy of conjugate cam.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Fig. 1 looks schematic representation for the master of the utility model conjugate cam drive mechanism.
Fig. 2 is the plan view of Fig. 1.
Fig. 3 is the schematic perspective view of the utility model conjugate cam drive mechanism.
Embodiment
To a kind of conjugate cam drive mechanism shown in Figure 3, comprise transmission shaft 1 and conjugate cam 2 referring to Fig. 1, offer keyway 1-1 on the described transmission shaft 1, transmission shaft 1 is driven by drive unit and rotates, and described transmission shaft 1 is a single piece with described conjugate cam 2.
In the utility model, described conjugate cam 2 and transmission shaft 1 can be distinguished processing separately, then described conjugate cam 2 is fastened on the transmission shaft 1 by interference fit, thereby both are constituted a single piece.
Described transmission shaft 1 also can adopt common forging manufacturing process with described conjugate cam 2, and one is processed into a single piece.Certainly, also can to process by means one such as roll are rolling be a single piece for transmission shaft 1 and described conjugate cam 2.
For ease of the processing of conjugate cam and the machining accuracy that improves conjugate cam, the peak or the minimum point of described conjugate cam 2 can be arranged on the symmetry center face 3 of keyway 1-1 on the described transmission shaft 1, the locating basis face during as machining cam with the symmetry center face 3 of keyway 1-1 like this helps improving the machining accuracy of conjugate cam.
Through on probation, transmission is reliable and stable on warp knitting machine for the utility model, and loosening phenomenon does not take place between conjugate cam and the transmission shaft, the transmission accuracy height, and manufacturing procedure is few, has obtained good practical effect.
