Snekkeaksler og gearkasser

Hvis du har en gearkasse, spørger du dig måske selv, hvad den bedste snekkeaksel er til din anvendelse. Der er en række ting at overveje, såsom den konkave form, antallet af gevind og smøring. Denne artikel vil beskrive hvert eneste aspekt og hjælpe dig med at vælge den rigtige snekkeaksel til din gearkasse. Der findes mange muligheder på markedet, så tøv ikke med at shoppe rundt. Hvis du er ny i gearkassernes verden, så læs videre for at lære mere om denne almindelige type gearkasse.

Konkav tilstand

The geometry of a worm gear differs significantly dependent on its producer and its meant use. Early worms had a basic profile that resembled a screw thread and could be chased on a lathe. Later on, instruments with a straight sided g-angle were produced to make threads that had been parallel to the worm’s axis. Grinding was also designed to boost the finish of worm threads and minimize distortions that arise with hardening.
To choose a worm with the appropriate geometry, the diameter of the worm gear have to be in the very same device as the worm’s shaft. After the fundamental profile of the worm gear is identified, the worm gear teeth can be specified. The calculation also includes an angle for the worm shaft to prevent it from overheating. The angle of the worm shaft ought to be as shut to the vertical axis as possible.
Dobbeltomhuldende snekkegear har derimod ikke en hals hele vejen rundt om snekken. De er spiralformede gear med en lige snekkeaksel. Da snekkens emalje er i kontakt med hinanden, skaber de betydelig friktion. I modsætning til dobbeltomhuldende snekkegear er ikke-halsede snekkegear mere kompakte og kan håndtere mindre snekkehjul. De er også nemme at fremstille.
Snekkegear fra forskellige producenter tilbyder mange fordele. For eksempel er snekkegear en af ​​de mest effektive metoder til at øge drejningsmomentet, mens materialer af lavere kvalitet som bronze er vanskelige at smøre. Snekkegear har også en lavere fejlrate, fordi de giver betydelig spillerum i designprocessen. På trods af forskellene mellem de to specifikationer er den samlede effektivitet af et snekkegearsystem den samme.
Den kegleformede orm er endnu en type. Dette er en teknologisk plan, der kombinerer en lige ormeskaft med en konkav bue. Den konkave bue er også et nyttigt hjælpemiddel. Orme med denne form har mere end tre kontaktpunkter på samme tid, hvilket betyder, at de kan reducere en stor diameter uden unormal belastning. Det er også en relativt billig model.

A very good worm equipment requires a excellent thread sample. There are a couple of important parameters that decide how good a thread pattern is. First of all, the threading pattern must be ACME-threaded. If this is not possible, the thread need to be made with straight sides. Then, the linear pitch of the “worm” need to be the same as the round pitch of the corresponding worm wheel. In simple conditions, this indicates the pitch of the “worm” is the exact same as the circular pitch of the worm wheel. A fast-change gearbox is usually employed with this kind of worm equipment. Alternatively, guide-screw alter gears are utilized instead of a quick-change gear box. The pitch of a worm equipment equals the helix angle of a screw.
A worm gear’s axial pitch should match the circular pitch of a gear with a larger axial pitch. The circular pitch is the length amongst the points of tooth on the worm, although the axial pitch is the distance in between the worm’s tooth. Another element is the worm’s lead angle. The angle between the pitch cylinder and worm shaft is called its guide angle, and the increased the guide angle, the better the performance of a gear.
Snekkegearets tandgeometri varierer afhængigt af producenten og den tilsigtede anvendelse. I tidlige snekkegear lignede gevindskæringen gevindet på en skrue og var meget let at udføre ved hjælp af en drejebænk. Senere forbedrede slibning snekkegevindets overflader og minimerede forvridninger fra hærdning. Som følge heraf har de fleste snekkegear i dag en gevindprøve, der svarer til deres størrelse. Når du vælger et snekkegear, skal du sørge for at kontrollere antallet af gevind, før du køber det.
A worm gear’s threading is vital in its procedure. Worm teeth are generally cylindrical, and are organized in a sample related to screw or nut threads. Worm enamel are frequently formed on an axis of perpendicular in contrast to their parallel counterparts. Simply because of this, they have higher torque than their spur equipment counterparts. In addition, the gearing has a lower output speed and substantial torque.

Forskellige typer snekkegear bruger forskellige gevindstørrelser på deres planetgear. Et enkeltgevindet snekkegear bør ikke anvendes med en dobbeltgevindet snekke. Et enkeltgevindet snekkegear bør anvendes med en enkeltgevindet snekke. Enkeltgevindede snekker er mere effektive til hastighedsreduktion end dobbeltgevindede typer.
The quantity of threads on a worm’s shaft is a ratio that compares the pitch diameter and quantity of enamel. In basic, worms have 1,2,4 threads, but some have 3, 5, or 6. Counting thread starts can help you decide the amount of threads on a worm. A solitary-threaded worm has fewer threads than a numerous-threaded worm, but a multi-threaded worm will have more threads than a mono-threaded planetary gear.
To measure the amount of threads on a worm shaft, a modest fixture with two ground faces is utilized. The worm should be eliminated from its housing so that the completed thread area can be inspected. Right after identifying the amount of threads, simple measurements of the worm’s outside diameter and thread depth are taken. Once the worm has been accounted for, a solid of the tooth place is manufactured making use of epoxy content. The casting is moulded between the two tooth flanks. The V-block fixture rests from the outside the house diameter of the worm.
The round pitch of a worm and its axial pitch have to match the circular pitch of a more substantial equipment. The axial pitch of a worm is the distance amongst the points of the tooth on a worm’s pitch diameter. The direct of a thread is the length a thread travels in a single revolution. The guide angle is the tangent to the helix of a thread on a cylinder.
The worm gear’s speed transmission ratio is primarily based on the amount of threads. A worm gear with a high ratio can be effortlessly decreased in a single stage by using a established of worm gears. Even so, a multi-thread worm will have much more than two threads. The worm equipment is also far more effective than one-threaded gears. And a worm gear with a high ratio will permit the motor to be used in a range of applications.

Smøring

Smøring af et snekkegear er særligt vanskeligt på grund af dets friktion og høje glidende bevægelseshastighed. Heldigvis findes der mange alternativer til smøremidler, såsom blandingsolier. Blandede olier er mineralbaserede smøremidler formuleret med 10 % eller mere fedtsyrer, rust- og oxidationshæmmere og andre tilsætningsstoffer. Denne blanding resulterer i forbedret smøreevne, reduceret friktion og lavere glidende bevægelse.
When picking a lubricant for a worm shaft, make confident the product’s viscosity is correct for the type of gearing utilized. A low viscosity will make the gearbox difficult to actuate and rotate. Worm gears also bear a better sliding movement than rolling movement, so grease must be ready to migrate evenly all through the gearbox. Repeated sliding motions will push the grease away from the contact zone.
En yderligere overvejelse er gearets slør. Snekkegear har store udvekslingsforhold, nogle gange 300:1. Dette er kritisk til elektriske applikationer, men er samtidig ineffektivt. Snekkegear kan generere varme under glidebevægelsen, så et smøremiddel af høj kvalitet er afgørende. Denne type smøremiddel vil reducere varme og sikre optimal ydeevne. De følgende tips vil hjælpe dig med at vælge det rigtige smøremiddel til dit snekkegear.
In lower-pace programs, a grease lubricant may possibly be sufficient. In increased-speed apps, it is very best to apply a artificial lubricant to stop premature failure and tooth dress in. In each instances, lubricant option is dependent on the tangential and rotational pace. It is essential to follow manufacturer’s suggestions with regards to the selection of lubricant. But bear in mind that lubricant selection is not an simple task.
