Modernization of an old balancing machine with hard-bearing supports
Earlier in the article, I described the modernization of an old balancing machine with soft-bearing supports. For such machines, we install the Balanset-1A balancing device in the case of machines with two supports, and the Balanset-4 in the case of machines with more supports.
Hard-bearing supports: design and advantages
In this article, we will consider the modernization of an old balancing machine with hard-bearing supports. Their supports are made in the form of rigid plates with shaped grooves (slots). The natural vibration frequencies of these supports are significantly (at least 2-3 times) higher than the maximum rotational speed of the rotor being balanced on the machine.
Machines with hard-bearing supports are more versatile than machines with soft-bearing supports, as they usually provide the ability to balance rotors with a larger range of mass characteristics. An important advantage of these machines is also that they allow for high-precision balancing of rotors at relatively low rotational speeds, which can be within the range of 200-500 rpm and below.
Figure 1 shows a photograph of a typical balancing machine with hard-bearing supports.

How the support reacts to unbalance forces
From this figure, it can be seen that individual parts of the support formed by the shaped grooves have different stiffness, which under the influence of unbalance forces on the rotor can lead to deformations (displacements) of some parts of the support relative to others. (In figure 2, the more rigid part of the support is highlighted in red dotted lines, and its relatively compliant part in blue).

Sensors for measuring support deformation
To measure the specified relative deformations in machines with hard-bearing supports, either force sensors or highly sensitive vibration sensors of various types, including non-contact displacement sensors, can be used.

Nikolai Shelkovenko
Nikolai Shelkovenko is a vibration analysis engineer and the founder and CEO of Vibromera. For more than 15 years he has balanced rotating equipment in the field rather than on a test bench: mulchers, industrial fans, crushers, centrifuges, shafts and spindles. That work is what the Balanset instruments grew out of — they were designed as a tool a specialist can carry to the machine and use alone, on site, not as laboratory equipment. Vibromera was founded in 2017 and has been based in Porto, Portugal, since 2023. Development, assembly and support of the Balanset line all happen here. The flagship instrument is the Balanset-1A, a portable analyser for single- and two-plane balancing and for vibration diagnostics. Nikolai is personally involved in customer support, in working through difficult balancing cases and in the development of the software. He works with customers worldwide, in any language.
