Gearbox parts & its Functions | Gearbox suppliers in delhi

The gearbox is a mechanical device which is used to increase the output torque or to change the speed (RPM) of a motor. The shaft of the motor is connected to one end of the gearbox and through the internal configuration of the gears of a gearbox, provides a given output torque and speed determined by the gear ratio. Precimotion is one of the leading Gearbox suppliers in delhi. While making our range of products such as Servo planetary, Strain wave gearboxes, Six axis robots, our team of personnel makes sure that international guidelines are being followed. The range is supplied to diverse industries for major industrial applications. Gearbox suppliers in delhi

To maintain engine speed on all the conditions of load and vehicle speed, the gearbox uses a system to maintain engine speed, while sacrificing the same road speed. To enable the engine to run faster on-road wheels as well as to multiply the torque, a gearbox is required.

PARTS OF GEARBOX:

1. Clutch Shaft / Driving Shaft / Input Shaft

It is a shaft that takes power from the engine to supply another shaft. The clutch shaft or driving shaft is connected through the clutch and when the clutch is engaged then the driving shaft also rotates. Only one gear is fixed on the clutch shaft and the engine rotates with the same speed as the crankshaft. In addition, the driving shaft and the main shaft are in the same line.

2. Counter Shaft / Layshaft

It is a shaft that connects directly to the clutch shaft. It has a gear which connects it to the clutch shaft as well as the main shaft. It can be run at the engine speed or below engine speed according to gear ratio.

3. Main Shaft / Output Shaft

The main shaft or output shaft rotates at different speeds and also provides the necessary torque to the vehicle. The output shaft is a splined shaft, so that a gear or synchronizer can be moved to engage or disengage.

4. Bearings

These are required to support the rotating part and reduce friction. The gear box has both a counter and the main shaft which is supported by the bearing.

5. Gears

They are used to transmitting the power from one shaft to another shaft. The amount of torque transmitted through the gears depends on the number of teeth and size of the gears. Higher the gear ratio and higher the torque / acceleration and lower the speed. All the gears except those on the main shaft are fixed to their respective shafts; they can slide in any of the directions along the shaft.

6. Gear Selector Fork

They are simple devices that use a lever that selects gears to engage in disengages mechanisms. The motion of the lever slides the engaging part on the shaft. It depends on the type of gearbox whether the lever slides the gear or synchronizer that is already forged along the main shaft.

PURPOSE OF GEARBOX:

1. It helps the engine to disconnect from the driving wheels.
2. It helps the running engine connect to the driving wheel smoothly and without any shock.
3. It provides the leverage between the engine and driving wheels to be varied.
4. This helps in reducing the engine speed in the ratio of 4: 1 in case of the passenger cars and in a greater ratio in case of heavy vehicles like trucks and lorries.
5. It helps the driving wheels to drive at different speeds.
6. It gives the relative movement between engine and driving wheels due to flexing of the road spring.

FUNCTION OF GEARBOX:

• Torque ratio between the engine and wheels should be varied for fast acceleration and for climbing gradients.
• It provides the means of reversal of vehicle motion.
• Transmission can disconnect from the engine by the neutral position of the gearbox.
