Drive Types & Correction Systems

Universal Horizontal Balance Machines are available in 3 drive configurations to suit all applications. The first is “Belt Drive” which requires no adapters and no direct connection to the component. The belt can either “over drive” as the photo below which is common for smaller machines and automated machines when fast load time is required.

The second “belt drive” system is an “under drive” which means the belt loops around the job, this variant allows a larger range of diameters that can be driven thus very flexible. The second drive type is an “End Drive” which usually means a cardan shaft is connected to the component through an adapter (can be quick fit), this means the drive speed is the actual speed that the drive unit outputs. This option allows a greater amount of torque to be applied at a greater rate so components like fan impellers and other parts with high inertia can be accelerated and decelerated at a faster safer rate.

The third option is “dual drive” which means the machine is fitted with both end and belt drive to allow an even greater flexibility, this option can be common when a large range of different components are to be balanced on one machine. All 3 options have great flexibility and Universal balancing will advise the correct method of drive type to suit your application. All drive types have infinitely variable speed via an AC inverter control system.

Correction Systems

Correction systems can be fitted to any horizontal balancer, this allows correction actually on the machine. A common system is a drill unit that can be either vertically or axially mounted. Correction systems can be manual or automatic or a high breed of a manual machine which is to have "auto depth control" on a manual machine thus taking any guess work from correcting unbalance by drilling on a machine, the operator just turns the component to the prompted highlighted position the drills at that point until the cursor disappears ie the correct depth is achieved, this with software vector segmenting program provides an intermediate between manual and auto status.

A Semi-Automatic Horizontal Balance with twin drill heads to allow correction to be made actually on the machine via axial drilling. The machine operation is as follows:

The operator loads the part, closes the guard door, machine is started and runs to the balance speed. Balance results are taken and the rotor decelerates to the first correction position. Air clamps are activated to hold the rotor for drilling. An air feed drill corrects the part at positions determined by the measuring system many special features are included in the software for this whole process. Once all correction in planes 1 and 2 are complete an Audit check balance is carried out, the audit can be every part or every set number of parts. If the audit check is within the programmed tolerance then the rotor decelerates to zero so the part can be removed from the machine. If the audit check is outside of the required tolerance then the rotor decelerates to the required position for further correction routine.
