Overview

Gearboxes, also known as gear drives, are the arrangement of their shafts or the way that they mount to the driven equipment. However, it is important to realize that shaft arrangement and mounting are two different characteristics of the drive.

Therefore, it is important to know both aspects to successfully determine the best gearbox for your application. The shaft arrangement on a gear drive is the location of the high-speed and low-speed shaft extensions relative to each other.

This is dictated by the position of the motor and driven equipment and is sometimes constrained by the physical space of the application. The orientation of high and low-speed shafts as they relate to the naming of the different types of gear drives may seem very simple, but there are reasons why you would choose one over the others when determining the best gearbox for your application.

The primary determinant for selecting the type of gearbox is space limitations in a system. Because the shafts are oriented differently, your driving equipment, or motor, will be in a different location depending on which type of gear drive is selected.

Speed Variations:

By feeding fixed speed to Variator, steeples speed variation can be obtained from

Max. Speed = 1.7 x Input speed to
Min. Speed = 1/7 x input speed
Max.Speed/Min.Speed = 12:1 to 3:1 depending upon selection

_________________________________________________________________

Torque Multiplier:

When speed is reduced, Variators can replace Gear Boxes.

_________________________________________________________________

Speed Multiplier:

Up to 1.7 times input speed without necessity of speed increasing gear.

_________________________________________________________________

High Output Torque – Over Load Capacity:

Up to the standstill of an electric motor of the same power acting as a mechanical clutch.

_________________________________________________________________

High Efficiency:

Overall 85% throughout full speed range ideally used for constant power transmission applications in all types of Industries.

__________________________________________________________________

Speed Holding:

Quite stable with uniform load and within 0.25% with Max. Load.

__________________________________________________________________

Reliability:

Drive is highly reliable with long life as load is equally distributed on number of conical Rollers, which are hardened, and ground to close tolerance.

__________________________________________________________________

Simple Design:
Can be attended by skilled fitter as no electronic/electrical parts/circuits are involved.

__________________________________________________________________
Compactness:
High Power Transmission capacity with small dimensions.

__________________________________________________________________
Speed Control:
Quick and simple. By rotating control knob in running condition only.

__________________________________________________________________
Free From Noise And Vibrations:
No moving parts like Chins, Belts, etc. Drive is through rolling action of PRECISION ROLLERS, which are continuously lubricated. All components are well balanced.

__________________________________________________________________
Bi-directional Rotation Of Output Shaft:
Clockwise/Anti Clockwise depending upon Input shaft rotation, viz. Anti Clockwise/Clockwise respectively.
__________________________________________________________________
Totally Enclosed Unit:
Ideal for hazardous zones.
__________________________________________________________________
Maintenance:
Practically maintenance free. Only ensure proper lubrication.
__________________________________________________________________
Collinear Input & Output Shaft:
In-Line Input and Output Shafts.
__________________________________________________________________
Before Selecting the Variator Consider Following:

Load Factors:

Uniform load: 1
Medium shock load: 1.5
Heavy shock load: 2

Service factors:

8 Hours running – 1
16 Hours running – 1.25
24 Hours running – 1.5

Efficiencies of various driving elements used in drive system.

For frequent start/stop, reversal operation, and high moment of inertia load consult us

For Further Reduction Use At The Output Shaft Of The Variator:

Chain drive (positive)
Belt drive (slip occurs) For reduction up to 4:1
Suitable reduction gear boxes (worm/helical) by Elmrad

Uses

Extruder Gear Box Uses and Applications

We shall use fA to designate the application factor (Ca or Ka in AGMA standards and Ka in ISO standards) pr external overload factor deriving from the operating characteristics of the driving and driven engines are defined according to uniform operation. Operation with light shocks and operation with medium shocks: also three classes of driven machine are defined according to uniform loads, medium shock loads, or heavy shock loads. Consult Table 1 for a general explanation.

Table 1 :-

Driven Machine
U	M	S

Uniform Operation	Electric Motors, Turbines, Hydraulic Motors	1	1.25	1.75
Operation With Light Shocks	Combustion engine with 4-6 cylinders	1.25	1.5	2
Operation With Medium Shocks	Combustion engine with 1-6 cylinders	1.5	1.75	2.25

	U = Machine with Uniforms Load
	M = Machine with Medium Shock Load
	S = Machine with Heavy Shock Load
