Balancer drive system design is very important. What factors should be considered? Huakezhi Creative Balancer technician mainly analyses the following aspects about the drive system: design considerations of the drive system of the balancer, types of drive systems, selection of drive motor types and power, and installation of the drive system.
Drive system is one of the three major systems of the balancing machine (i.e. drive, display measurement and support). Its performance has a great influence on the performance of the balancing machine. The balancer drive system not only enables the balancer to work at full load to the rated operating speed, but also requires economy, reliability and easy control. In addition, smooth driving is required in high-precision balancing machines. In some balancers operating at a constant speed, the stability of the speed is required.
The design of the drive system considers the following points when designing (or selecting) the drive system of the balancer:
I. Motor driving power shall ensure that the balancer has sufficient starting torque and has the ability to work to the required balancing speed under maximum load (full load).
2. Drive stability shall ensure smooth rotation of balancer, i.e. the influence of instability caused by drive on unbalanced signal shall be limited to a minimum.
3. Acceleration time and deceleration time should be reduced as much as possible to improve the balancing efficiency of the balancer. In this way, the speed increases or reducers should be set in the speed range as appropriate.
IV. The speed range drive system shall meet the requirements of the speed range of the balancer, especially the maximum speed of the balancer.
V. The nature of machine work shall mainly consider the following two aspects:
1. Does the machine only need to work at one to several rated speeds or does it require continuous speed adjustment
2. Whether the balancing workpiece (rotor) is a flexible or rigid rotor. Generally, when the flexible rotor is balanced dynamically, the requirement for fine-tunability and stability of machine speed is high. For rigid rotors, the requirements can be reduced accordingly.
6. If the operation of the machine is technically possible by using two or more drive systems, then further consideration should be given to the specific operation characteristics of the balancing machine, such as the convenience of loading and unloading the rotor, before deciding the drive mode.
Seventh, each drive of economy can not be perfect, and always has its own shortcomings. Usually the more functions the system has, the more expensive it is. Therefore, economic compromise should be considered and its gains and losses should be measured comprehensively.
