Three Factors Affecting Torque Value of Cam Indexer

In a turntable type automation device, under the premise that the motor is used as the driving source, the motor is connected with the input shaft of the indexer, and the input shaft drives the output shaft for mechanical movement. As the whole mechanism of the indexer, the stability of the action of the input shaft , Determines the stability of the entire indexer, which is what we call the torque value of the cam indexer.

From the perspective of the principle of mechanical motion, there are three main factors that affect the input axis of the indexer:

1. Mechanical inertia, any machine will produce mechanical inertia when it is in motion, but the inertia is different due to the performance of the machine itself. The input axis of the indexer rotates continuously, and the output axis performs intermittent or rocking mechanical actions. The process of moving to stop will produce inertia of power switching. Similarly, the process of moving from stop to moving will also produce corresponding mechanical inertia. The inertia generated by this indexer itself is largely derived from the cam structure curve of the indexer. The smoothness of the point, line and surface transmission action of the cambered cam and the needle bearing of the output shaft can also be called the degree of mechanical coordination, and the processing curve of the cam comes from the processing program design of the cambered cam, so different equipment The processed cams will be essentially different in application, and this is the reason. For the distinction between imported equipment and domestic processing equipment, from the current stage, this is also a very important factor. I believe that in the near future, with the advancement of technology, our domestic processing equipment will also be able to reach the level of machinery technology in developed countries.

2. The reaction force is mainly generated by the input shaft of the indexer in the case of chain transmission or multi-angle transmission. The transmission of chains or gears causes mechanical gaps in the input. Noise and vibration are unavoidable, and it will also aggravate the indexer. Inertia other than one's own inertia. If it is necessary to use, it is recommended to use it at a low speed and with increased lubrication.

3. In the rotary transmission equipment, the bending, eccentricity, deformation and displacement of the connecting hole between the motor and the indexer shaft will also affect the stability of the indexer torque value. This requires that when the indexer is installed, the rules for mechanical installation must be observed, and the connection between the shaft and the bearing used should be tested under conditions before the connection is made.
