Balance machine purchase basic knowledge

Even if you have used a multi-year balancing machine, you will not necessarily be aware of the differences between the various brands and price products on the market. The following will introduce some basic knowledge on several issues frequently asked by users for reference.

Soft support and hard support

The dynamic balance machine is divided into two kinds: soft support and hard support. Theoretically, the soft support balancer can obtain higher test accuracy. However, this can only be distinguished in extremely sophisticated tests. For the driveshaft balancing machine, the precision that can be achieved by the hard support is far beyond the actual needs. If the accuracy of a drive balancing machine is found to be insufficient, it must be the result of other factors. Among the factors affecting the balance accuracy, soft and hard support is only a trivial factor.

Accuracy

Since the technology is very mature, the error generated by the electronic measurement part is already very small. There are two main influencing factors:

1. The connection mode between the transmission shaft and the balancing machine. 2, balancing machine spindle machining accuracy.

Weight loss rate

The weight loss rate of the balancing machine is relatively high, and the balance can be completed with a small number of rotations. The factors that affect the rate of weight loss are:

1. Is the calibration of the balance machine accurate?

2. The weight and position of the balance weight placed during operation are accurate.

3, the size of the gap between the transmission cross shaft and telescopic slide keys.

Rotating speed

A soft-support balancing machine must detect more than three times the resonance speed (the higher the speed, the higher the rate of weight reduction), so higher speeds are generally used.

Hard-supported balancing machines generally use lower speeds (especially heavy-duty drives), and the speed of rotation is also related to the sensitivity of the sensors used.
