Propeller shaft

Propeller shaft

Propeller shaft is used to transmit the drive force generated by the engine to the axles when the engine and axles are separated from each other. When the shaft is longer it is more liable to bend and bending is further promoted when rotation is applied causing vibrations and resulting in an increase in noise. Hence in order to suppress vibrations arising from any cause the propeller shaft is designed.

All rear drive type vehicle must have a propeller shaft to move a vehicle. We will discuss about the main functions of propeller shaft.

Main functions of propeller shaft

Propeller shaft or a cardan shaft is a mechanical component for transmitting torque and rotation, usually used to connect other components of a drive train that cannot be connected directly because of distance or the need to allow for relative movement between them. Propeller shaft make any machine move. Drive shafts are carriers of torque: they are subject to torsion and shear stress, equivalent to the difference between the input torque and the load. They must therefore be strong enough to bear the stress, whilst avoiding too much additional weight as that would in turn increase their inertia.

In case, the propeller shaft fails, the rear wheels wouldn’t be able to move. But don’t worry because propeller shafts won’t just fail instantly. Propeller shaft slowly deteriorate over time and gives you the chance to notice the symptoms of the failure shaft early on. After recognizing the failure you have to take immediate action and replace the propeller shaft.

Single and multiple piece propeller shafts: 

A single piece shaft is a wonderful tool that helps to impart torque to the drive gears. A universal joint shaft connects the device to the driving assembly that helps in the movement of the vehicle. The transmission system is located between the propeller shaft and differential. You can contact the cardan shaft supplier to replace the device if it is not transmitting power from the gearbox to the axle.

• In a two-piece system, the shaft is supported with the help of the rubber mounted bearing. Make sure to buy the stuff from reputed retailers to get the desired results. Division of the propeller shaft into two or three parts helps to lower the critical number of revolutions to eliminate the vibration problems.
• Dynamic damper is inserted into the pipe to decrease the noise level to a great extent. You should buy propeller shafts from cardan shaft manufacturers in India at lower costs to optimize the operational expenses. It will go a long way in making the business profitable.

Propeller Shaft

Propeller Shaft is the shaft that transmits power from the gearbox to the differential gear in a motor vehicle from the engine to the propeller in a boat or flying machine.

Propeller shaft, sometimes called a cardan shaft, transmits power from the gearbox to the rear axle. Regularly the shaft has a tubular section and is made in maybe a couple piece constructions.

The two-piece arrangement is supported at the midpoint by an elastic mounted bearing. In order to transmit the power from the last drive assembly to the road wheels short drive shafts are needed to be incorporated in both front and rear wheel drive layouts.

Types of Propeller Shaft:

1. Single-Piece-Type Propeller Shaft:

• Used in vehicles with a short distance between the engine and axles, and MR based four-wheel-drive vehicles.
• The friction weldingadopted at the junction contributes to an improvement in the strength, quality, and durability of the junction.

2. 2-piece-type/3-piece-type Propeller Shaft:

• Utilized as a part of vehicles with a long distance between the engine and axles, and Front engine front drive base four-wheel-drive vehicles.
• The division of the propeller shaft into two- or three-parts allows the critical number of revolution to lowered preventing vibration issue from occurring, when the overall length of the shaft increased.

Need for Offset Shaft Alignment

Cardan Shaft or Offset Shaft with u-joints or typically called as drive shaft is used to transfer power from a driver shaft to a piece of driven shaft. Offset shaft means the shafts of the driver and driven elements are not in line with each other. In the cardan shaft assembly there can be any number of u-joints. For example a single Cardan shaft means in a cardan shaft assembly there is a u-joint at each end of a shaft. If cardan shaft assembly contains double Cardan shaft then it means that three or more u-joints in a shaft are used. But the most encountered shaft in an industry is a single Cardan shaft.

There are two parts that must be understood, proper phasing and angularity of the input and output shafts.

1.      Phasing refers to the position of the yokes that are part of the shaft. The two ends, or yokes, must be positioned parallel, or in line with each other. Failure to do this will cause the driven machine to speed up and slow down twice for every revolution of the driver. This will cause runability problems, as well as high vibration issues.

2.      The angularity of the input (driver) and output (driven) shafts in relation to the main shaft element must be equal at each end of the shaft. Based on speed and load some guidelines are established cardan shaft manufacturers industry about maximum allowable angle between the shaft and the yokes. The best place to get the proper information is from the cardan shaft manufacturers.

Alignment part of the job

When the driven machine and the drive are aligned correctly, place the shaft ends in the correct position. Shafts when aligned correctly make the angle of the yokes on both shaft ends equal when the driven and driver are on parallel planes in the vertical and horizontal axes. When driver and driven machines are not aligned, it directly affects on the speed of the driven machine and it is fluctuated.  That means the worse the angular misalignment, the worse the speed fluctuation.
