SHE Series, Normal Duty Planetary Gearbox

SHE Series, Normal Duty Planetary Gearbox

Description

The planetary gearbox is used to change the speed and increase the torque in power transmission. More precisely, this gearbox is used when you need to change the speed and convert a fast rotational movement into a slower rotational movement with more torque.
As a brief explanation, the working process of the planetary gearbox is as follows:
This gearbox includes a sun gear, a ring gear and a pinion carrier. When the sun gear connected to the motor rotates, it rotates the carrier gears and, in connection with the fixed ring gear, reduces the output speed and increases the torque proportionally.
planetary gearboxes are used in industrial machineries, cars, energy equipment, power generation and many other applications. Due to the ability to change speed and increasing the torque, this gearbox is very useful when there is a need to accurately control speed and torque changes.

General specifications

In this category of gearboxes, according to the input speeds, 1500, 1000, 500 (R.P.M) the following values are considered:
Reduction ratio (i), output speed (n2), output torque (T2), nominal power (P2), maximum torque (T2max), thermal power (PT)

Tips:
1- The maximum torque column is for selection in short periods.
2- If the nominal power is more than the thermal power, oil cooler should be used.
PD = Foot mounted.
PDA = Foot mounted 90 degrees.
EM, ED, ET, EQ = Flange mounted (vertical).
EC =Flange mounted 90 degrees.

Different mounting positions

In this category of gearboxes, the input and output are aligned, and according to the place of consumption, hollow output, solid output, shearing disk output, and splined output can be produced in foot mounted and flange mounted (vertical) types.
In addition, the input is produced as B5 flanged or a half-flange B14 according to the type of connection.

Overall dimensions

In overall dimensions tables and figures, we have tried to provide useful dimensions and characteristics. These characteristics should include the number of modules, the type of output connection, and the frame of the input connection in vertical, 90-degree vertical, foot mounted, and 90-degree foot mounted gearboxes.
