In the automatic turntable machine, the matching of the cam divider and the selection of the motor and reducer are very important. According to the indexing time, intermittent time, rotation torque and other factors, the appropriate motor and reducer type, power, and reduction ratio should be determined. The correct matching and selection can ensure the stable operation and working efficiency of the turntable machine. The following will introduce the matching common sense in detail.
1. Determine the motor selection: If the continuous operation of the motor can meet the indexing time and intermittent time of the rotary table, you can choose a normal motor. If the intermittent time is not enough, you need to stop the motor to extend the intermittent time. If the number of brakes is less than 20 times, you can choose a brake motor. If it is more than 20 times, it is best to choose a brake clutch to avoid excessive heating and burning of the motor. If using a frequency converter drive, you can set the deceleration time to the minimum and add a resistor to achieve rapid braking.
2. Determine the motor power: First calculate the output torque of the cam divider, then convert it into the torque of the input shaft, and finally determine the required motor power based on the torque.
3. Determine the reduction ratio of the reducer: The reduction ratio is determined by the indexing time of the cam divider . Calculate the intermittent time based on the indexing time and the drive angle, and then calculate the input shaft speed based on the time required to complete one division. Finally, determine the reduction ratio of the reducer based on the input shaft speed and the indexing time.
4. Determine the reducer type: Select the appropriate reducer type according to the installation space and customer needs. The worm reducer can be directly connected to the cam divider, and the gear reducer can be driven by a synchronous belt or chain.
Through the above process, the matching scheme of cam divider, motor and reducer can be determined. Reasonable selection and matching can ensure the stable operation and working efficiency of the turntable machine. In practical applications, calculation and selection need to be made according to specific circumstances to ensure the accuracy and reliability of the matching scheme.
The matching of cam divider, motor and reducer involves many factors, such as indexing time, intermittent time, rotation torque, etc. When selecting a motor, the operation mode, braking times and braking method should be considered. When selecting a reducer, the reduction ratio and reducer type should be determined. Through reasonable matching and selection, the stable operation and working efficiency of the turntable machine can be guaranteed, and the production benefits can be improved.
