Ved drift lineære aktuatorer, er der mange produktspecifikationer, som brugerne skal forstå. Nogle eksempler på aktuator specifications that are important may include speed, force, current draw, and dimensions. There is however one element of a linear actuator that can be tricky to gauge, the støjniveauMange brugere kender ofte ikke de ideelle støjniveauer eller begrænsninger med sikkerhed, før deres applikation med lineære aktuatorer kører, hvorved de indser, at støjniveauet kan være for højt. Selvom det er muligt at tilbagevenden tidligere aktuatorer og udskifte den med en anden enhed for at opnå en lavere støj fra en lineær aktuator, vil det kræve tid og ressourcer at sende enheden tilbage og købe en ny. I andre tilfælde kan det også være muligt, at der ikke findes en enhed med et lavt nok støjniveau til at opfylde kravene i en bestemt applikation. Heldigvis er der måder at overvinde støjen fra den aktuator, der blev brugt. I denne artikel vil vi gennemgå flere løsninger til at overvinde den høje mekaniske støj, der genereres fra lineære aktuatorer.
Driftsstøjen fra vores aktuatorer vil være angivet på hver af vores aktuatorer. datablad.
Gearkasse
Den mest almindelige mekaniske støj i lineære aktuatorer usually comes from the gearbox. The gears can turn incredibly fast depending on the gear ratio the gearbox uses. Since the noise created can be very loud, you can apply grease to the gearbox to reduce this noise. This will also reduce the friction between the gears and therefore reduce the noise. Note that when the actuator is operating in a high-temperature environment, the grease inside the gearbox can melt away, so it is ideal to reapply some gear grease after the units have been operated for a long time in a high-temperature environment.
On the other end of the spectrum, if the actuator is operating continuously in a very cold environment, the grease that acts as a lubricant can become condensed or even frozen. This will cause the unit to generate a lot of noise and may even break down. If that is the case, it is better to replace the grease in the gearbox with new lubricant that has a lower functional temperature.
Den sidste ting at være opmærksom på vedrørende støj fra gearkassen er typen af gear, som den lineære aktuator bruger. Metalgear genererer typisk mere støj, mens polymer- eller plastgear genererer mindre støj i sammenligning. Det er muligt at udskifte de indvendige gear i en aktuator fra metal til plastik, men denne type procedure skal udføres omhyggeligt. Metalgear anvendes generelt på grund af deres lange levetid og stærke struktur. Ved at udskifte dem med plastikgear risikerer brugerne at reducere aktuatorens levetid eller endda reducere lasteevnen.

Monteringsposition – Reducer overfladearealet
A lot of the noise from a linear actuator comes from the vibration in the actuator housing. As the electric motor runs, it causes vibration throughout the body of the linear actuator. When that vibration makes physical contact with a hard surface area, it will generate a lot of noise as a result. Therefore, it is a good idea to reduce the surface area that is making physical contact with the linear actuator as this will prevent most of the vibration noise. If that was not possible, users can also consider applying some soft material between the actuator housing and the hard surface area to reduce the linear actuator noise.
Find en ny aktuator
If the above options still don't reduce the noise from your actuator, then it would be time to find a new one. When looking for a replacement actuator to the current one, there are a few points that you should pay attention to. If your old actuator is a ball screw type, you may want to consider looking for an actuator that uses an ACME screw instead. Ball screw generally has great efficiency on power but tends to make a lot more noise when operating. On the other hand, ACME screw type actuators have lower efficiency, but the actuator sound is much quieter when running.

When a linear actuator is operating closer to its full load capacity, it tends to generate more noise. We recommend finding an actuator with a higher load rating when possible as it can still drive the application but with lower linear actuator noise. The actuators that have a higher load rating would usually have a slower speed as well so this method of reducing noise is more suitable for applications that can work with slower speeds.
