FLANGE OUTPUT ULTRA PRECISION GEARBOX
FLANGE OUTPUT ultra precision gearbox with high output torque provides performance and efficiency with torque and sturdiness. The helical toothed and one piece carrier design provides maximum radial load capacity as well as system reliability and stiffness. Four frame sizes are available with gear ratios from 1:3 to 1:100.
ZIPP GEAR Offers a complete series of inline and right angle, high precision, high dynamic, low backlash planetary precision gearboxes as well as fully customized gear train to meet your project requirements.
FLANGE OUTPUT ultra precision gearbox
A planetary gearbox refers to a gear system in which one or more ‘planet’ gears rotate around a central ‘sun’ gear. Typically, a planet carrier is driven by the input torque which rotates the planets around a fixed outer ring (sometimes referred to as the annulus). This in turn drives the sun gear which then provides the output torque. However there are examples of the other combination, such as the sun gear being fixed and the ring providing output torque.
FLANGE OUTPUT ultra precision gearbox advantages and disadvantages
The main advantage of planetary gearboxes are their high power transmission efficiencies. Typically this can be around just 3% per stage. Further to this, the high efficiency is delivered despite the compact design giving a large torque to size / weight ratio. Some of this is thanks to the load sharing that occurs across the multiple planet gears.
FLANGE OUTPUT ultra precision gearbox planetary gear sets & gear ratios
Any planetary gear set has three main components:
- The sun gear
- The planet gears and the planet gears’ carrier
- The ring gear
Each of these three components can be the input, the output or can be held stationary. Choosing which piece plays which role determines the gear ratio for the gear set. Let’s take a look at a single planetary gear set.
One of the planetary gear sets from our transmission has a ring gear with 72 teeth and a sun gear with 30 teeth. We can get lots of different gear ratios out of this gear set.
|A||Sun (S)||Planet Carrier (C)||Ring (R)||1 + R/S||3.4:1|
|B||Planet Carrier (C)||Ring (R)||Sun (S)||1 / (1 + S/R)||0.71:1|
|C||Sun (S)||Ring (R)||Planet Carrier (C)||-R/S||-2.4:1|
Also, locking any two of the three components together will lock up the whole device at a 1:1 gear reduction. Notice that the first gear ratio listed above is a reduction — the output speed is slower than the input speed. The second is an overdrive — the output speed is faster than the input speed. The last is a reduction again, but the output direction is reversed. There are several other ratios that can be gotten out of this planetary gear set, but these are the ones that are relevant to our automatic transmission.
