1 e. Working Principle:
Planetary gear box manufactured by AGNEE primarily have sun gear, planet gears, planet carrier assembly and ring gear.
Coaxial sun gear and planet carrier assembly (which comprises of carrier and 3 planet gears) rotates at constant centers along with the planet carrier
The input is from sun gear and the drive motion is through the planet carrier via planet gears and ring gears. The ring gear is generally stationary.
The rolling contact of the planet gears with the ring gear provides the appropriate reduction ratio.
The output shaft is connected to the planet gear assembly. Output shaft maintains the same direction of rotation as Input.
By varying the number of teeth of sun gear and planet gears it is possible to achieve various different ratios per stage.
Multi-stage gear boxes are manufactured by connecting the individual stages in sequence
When the input shaft that is na is rotated with n1 rotation it actually rotates sun gear (1). The sun gear simultaneously engages with planet gears (2) and also planet gears are in simultaneous engagement with Ring gear (3) which is stationary.
The input motion from sun gear is transmitted to coaxial planet carrier (5) through planet gears The ring gear (3) fixed to the frame functions as reacting gear component. Hence the planet carrier is rotated at lower rpm than the sun gear rpm. As the output shaft is connected to the planet carrier the output rpm n2 received at output shaft nb is lower than input shaft na.
The input rotation n1 applied to the sun gear is reduced to output rotation n2.
The planetary gear box are designed with the help of modern computer software using FEA method for weight and strength optimization.
1 f. Material Construction Ring Gear : Manufactured from high alloy steel and are hardened to absorb impact loads and increase wear resistance
Planet Gears : Manufactured from high tensile alloy steel and are case hardened or nitrated to achieve optimum strength and wear resistance. Bores of planet gears are ground. To increase load carrying capacity and uniform load distribution, planet gears are ground from and above size 401.
Sun Gear Manufactured from high tensile alloy steel and are case hardened or nitrated to achieve optimum strength and wear resistance. Sun gears are mounted on input shaft or carrier with the help of splined and in small models with keyways to achieve desired power transmission.
Planet Carriers : Planet carriers are manufactured from high alloy casting or forging or bars machined with CNC machining centers to achieve desired accuracy of planet pin holes run out and parallelism.
Shafts : Made from high tensile alloy steel & toughened to achieve maximum strength to transmit power and absorb impact load.
Casings : Made from close grained cast iron or cast steel to absorb vibration and support reaction loads and are designed using FEA. Bought out Parts : All standard parts such as bearings, seals hardware are procured directly from reputed manufacturers for genuineness & cost effectiveness
