Snekkeaksler og gearkasser

Hvis du har en gearkasse, spekulerer du måske på, hvad den ideelle snekkeaksel er til din maskine. Der er mange ting at tage højde for, såsom den konkave form, antallet af gevind og smøring. Denne rapport vil forklare hvert eneste element og hjælpe dig med at vælge den rigtige snekkeaksel til din gearkasse. Der er mange muligheder tilgængelige på markedet, så tøv ikke med at lede. Hvis du er ny i gearkassernes verden, så læs videre for at lære meget mere om denne velkendte type gearkasse.

Konkav form

The geometry of a worm gear differs significantly depending on its manufacturer and its supposed use. Early worms had a basic profile that resembled a screw thread and could be chased on a lathe. Afterwards, resources with a straight sided g-angle had been designed to create threads that were parallel to the worm’s axis. Grinding was also produced to enhance the finish of worm threads and minimize distortions that arise with hardening.
To select a worm with the suitable geometry, the diameter of the worm gear must be in the identical unit as the worm’s shaft. After the fundamental profile of the worm equipment is determined, the worm gear teeth can be specified. The calculation also includes an angle for the worm shaft to stop it from overheating. The angle of the worm shaft need to be as shut to the vertical axis as attainable.
Dobbeltomhuldende snekkegear har derimod ikke en hals tæt på snekken. De er spiralformede gear med en lige snekkeaksel. Da snekkens tænder er i kontakt med hinanden, genererer de betydelig friktion. I modsætning til dobbeltomhuldende snekkegear er ikke-halsede snekkegear mere kompakte og kan håndtere mindre belastninger. 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 komponenter af lav kvalitet som bronze er vanskelige at smøre. Snekkegear har også en lav fejlrate, fordi de giver betydelig spillerum i designprocessen. Trods forskellene mellem de to forventninger er den samlede ydeevne af et snekkegearsystem den samme.
Den kegleformede orm er en anden type. Dette er en teknologisk plan, der kombinerer en lige ormeskaft med en konkav bue. Den konkave bue er også et nyttigt brugsmønster. Orme med denne form har mere end tre kontakter på samme tid, hvilket betyder, at de kan reducere en stor diameter uden at have for meget tøj i. Det er også et forholdsvis billigt design.

Trådeksempel

A excellent worm equipment calls for a ideal thread sample. There are a few important parameters that determine how very good a thread pattern is. To start with, the threading pattern must be ACME-threaded. If this is not possible, the thread have to be produced with straight sides. Then, the linear pitch of the “worm” need to be the exact same as the round pitch of the corresponding worm wheel. In easy phrases, this indicates the pitch of the “worm” is the same as the circular pitch of the worm wheel. A quick-adjust gearbox is typically used with this variety of worm gear. Alternatively, guide-screw modify gears are utilized instead of a swift-change equipment box. The pitch of a worm equipment equals the helix angle of a screw.
A worm gear’s axial pitch must match the circular pitch of a equipment with a larger axial pitch. The round pitch is the distance amongst the details of enamel on the worm, while the axial pitch is the distance amongst the worm’s enamel. One more element is the worm’s lead angle. The angle among the pitch cylinder and worm shaft is called its direct angle, and the larger the guide angle, the greater the performance of a equipment.
Tandgeometrien på snekkegear kan variere afhængigt af producenten og den tilsigtede anvendelse. I tidlige snekkegear lignede gevindskæringen gevindet på en skrue og blev blot fræset med en drejebænk. Senere forbedrede slibning snekkegevindets overflader og minimerede forvrængninger fra hærdning. Som følge heraf har de fleste snekkegear i dag en gevindprøve, der svarer til deres dimension. Når du vælger et snekkegear, skal du sørge for at tjekke antallet af gevind, før du køber det.
A worm gear’s threading is crucial in its operation. Worm enamel are usually cylindrical, and are arranged in a pattern related to screw or nut threads. Worm enamel are often shaped on an axis of perpendicular compared to their parallel counterparts. Since of this, they have greater torque than their spur equipment counterparts. Furthermore, the gearing has a low output velocity and large torque.

Antal tråde

Forskellige typer snekkegear bruger forskellige mængder gevind på deres planetgear. Et enkeltgevindet snekkegear bør ikke anvendes med en dobbeltgevindet snekke. Et enkeltgevindet snekkegear skal anvendes med en enkeltgevindet snekke. Enkeltgevindede snekker er mere effektive til hastighedsreduktion end dobbeltgevindede typer.
The number of threads on a worm’s shaft is a ratio that compares the pitch diameter and number of tooth. In standard, worms have 1,2,4 threads, but some have three, five, or 6. Counting thread commences can aid you decide the number of threads on a worm. A single-threaded worm has much less threads than a a number of-threaded worm, but a multi-threaded worm will have much more threads than a mono-threaded planetary equipment.
To measure the quantity of threads on a worm shaft, a small fixture with two ground faces is utilized. The worm must be taken off from its housing so that the completed thread location can be inspected. Following identifying the quantity of threads, easy measurements of the worm’s exterior diameter and thread depth are taken. When the worm has been accounted for, a forged of the tooth place is manufactured utilizing epoxy content. The casting is moulded amongst the two tooth flanks. The V-block fixture rests against the outdoors diameter of the worm.
The circular pitch of a worm and its axial pitch must match the circular pitch of a greater equipment. The axial pitch of a worm is the distance between the details of the enamel on a worm’s pitch diameter. The guide of a thread is the distance a thread travels in one particular revolution. The direct angle is the tangent to the helix of a thread on a cylinder.
The worm gear’s speed transmission ratio is dependent on the amount of threads. A worm equipment with a large ratio can be effortlessly diminished in one particular step by making use of a established of worm gears. Nevertheless, a multi-thread worm will have a lot more than two threads. The worm equipment is also far more successful than single-threaded gears. And a worm gear with a high ratio will enable the motor to be utilised in a assortment of applications.

Smøring

Smøringen af ​​et snekkegear er særligt krævende på grund af dets friktion og store glidekontaktdrev. Den gode nyhed er, at der findes en række alternativer til smøremidler, såsom sammensatte olier. Sammensatte olier er mineralbaserede smøremidler formuleret med ti % eller flere fedtsyrer, rust- og oxidationshæmmere og andre tilsætningsstoffer. Denne blanding resulterer i forbedret smøreevne, reduceret friktion og reduceret glidebevægelse.
When selecting a lubricant for a worm shaft, make sure the product’s viscosity is right for the type of gearing utilized. A reduced viscosity will make the gearbox challenging to actuate and rotate. Worm gears also undergo a increased sliding motion than rolling motion, so grease have to be ready to migrate evenly throughout the gearbox. Repeated sliding motions will press the grease away from the make contact with zone.
En anden ting at overveje er gearets slør. Snekkegear har høje udvekslingsforhold, nogle gange 300:1. Dette er vigtigt til energiapplikationer, men er samtidig ineffektivt. Snekkegear kan producere varme under glidebevægelsen, så et smøremiddel af høj kvalitet er afgørende. Denne type smøremiddel reducerer varme og sikrer den bedste ydeevne. De følgende tips vil hjælpe dig med at vælge det rigtige smøremiddel til dit snekkeudstyr.
In lower-pace programs, a grease lubricant may possibly be enough. In increased-speed purposes, it’s very best to use a artificial lubricant to stop premature failure and tooth put on. In the two situations, lubricant selection is dependent on the tangential and rotational velocity. It is essential to stick to manufacturer’s suggestions relating to the choice of lubricant. But bear in mind that lubricant decision is not an effortless job.
