What parameters are required for the selection of hollow rotating platform?
Hollow rotary platform is a kind of rotary motion occasions that can replace DD motor and cam divider. It has obvious advantages. It integrates high transmission efficiency, high precision, high rigidity and high cost performance. It can be easily combined with any servo motor and stepping motor. It is a high-performance product with high load and high-precision repetitive positioning performance.
So how to choose Motorized Hollow Rotary Tables?
- First of all, we need to determine the diameter of the rotary table (customer’s working surface), the rotation speed, the load of the rotary table, etc. With these parameters, we can choose whether the approximate model, calculated torque, inertia, speed ratio, power of matching motor, accuracy error and reserved safety factor value meet the use requirements.
- The operation is as follows: select the size of the turntable according to the size of the workpiece, and narrow the selection range according to the size of the turntable; According to speed, torque and reduction ratio; Select the positioning method according to the installation method; Select the accuracy according to the working condition requirements.
- According to the corresponding data, such as the required torque (T), calculate by multiplying the sum of the load torque caused by the friction resistance and the acceleration torque caused by the moment of inertia by the safety factor:
Required torque T = (load torque [N.m] + acceleration torque [N.m] * safety factor.
In a word, it is necessary to understand the working conditions and working number of equipment; The pause time when one station is connected to another station, and the time when one station is completed; Whether the diameter of the other station is directly connected to the turntable, whether there are structural members in the middle, or whether the turntable is irregular; Load of each station, etc.
