What Is Centrifugal Clutch? – In the fully centrifugal type of clutches, the springs are eliminated altogether and only the centrifugal force is used to apply the required pressure for keeping the clutch in the engaged position.

What Is Centrifugal Clutch?

Centrifugal Clutch

A centrifugal clutch is a type of clutch that uses centrifugal force to connect two concentric shafts, with the driving shaft nested inside the driven shaft.

In the fully centrifugal type of clutches, the springs are eliminated altogether and only the centrifugal force is used to apply the required pressure for keeping the clutch in the engaged position.

Parts of Centrifugal Clutch

  1. Shoes – Shoes can move radially outwards and are held in position by spring.
  2. Guide or Spider:- Hold the shoes and guide their movement.
  3. Springs – Springs are used to engage and disengaging the shoe with the drum by centrifugal force.
  4. Friction lining:- The friction lining is provided to the outer surface of the driving shoe.
  5. Drum – The drum is connected to the driven member of the this clutch.

Construction of Centrifugal Clutch

This clutch consists of one driving member and one driven member. The driving member is made of a spider or guide which contains spring and brake shoes. It is manufactured in different designs as per the need. The driven member consists of friction lining on the inner surface. The driving member is connected with the engine crankshaft while the driven member advances to the transmission of the vehicle.

Working of Centrifugal Clutch

It works on a straightforward principle. The driving member rotates on the movement of the engine crankshaft. When engine speed reaches specified rpm it generates enough centrifugal force on the brake shoes. It pushes the shoes outward of the center, which results in the connection of brake shoes to the friction lining of the driven member, it generates friction and transmits the power.

When engine speed reaches the desired rpm clutch engages itself eliminating the need for manual operating linkage. To reduce or Increase the engagement rpm of the clutch, the spring is replaced. To increase the engagement rpm stiff spring is used; while to decrease the engagement speed soft spring is used.

Advantages and Disadvantages of Centrifugal Clutch

Advantages

  1. It is low in price because of fewer components and simple construction.
  2. Easy to operate.
  3. It doesn’t require any separate control mechanism like clutch pedal etc.
  4. It requires less maintenance.

Disadvantages

  1. Power transmission is limited due to slippage of shoes.
  2. It can not be used to transmit a high amount of torque.
  3. There will always be a power loss due to friction and slipping.
  4. Overheating problem due to quick engagement during running conditions.

Application of Centrifugal Clutch

  1. This clutch is used in an automatic transmission system.
  2. It is used in scooters, mopeds, and go-karts.
  3. It is used in chainsaws, lawnmowers, textile industries, etc.

Principle Centrifugal Clutch

This works on the principle of centrifugal force, which means when engine speed reaches a specific rpm (Revolutions per minute) it generates enough centrifugal force inside the clutch which results in clutch engagement and it transmits the engine power. At lower speeds, it disconnects itself to stop power transmission.

FAQ‘s

What is a clutch?

A clutch is a mechanical device that is used to transmit rotating motion or torque from the driving shaft to the driven shaft.

What is Centrifugal Clutch?

A centrifugal clutch is a type of clutch that uses centrifugal force to connect two concentric shafts, with the driving shaft nested inside the driven shaft.

What does centrifugal clutch do?

The basic purpose of a centrifugal clutch is to engage the engine with a load that is accelerated. It uses centrifugal force to turn the driveshaft and acts as a transmission activated by the engine’s increasing rpm.

How much HP can a centrifugal clutch handle?

Noram Centrifugal Clutch is designed to fit engines with fractional horsepower to 50 HP applications.

What are the advantages and disadvantages of centrifugal clutch?

Advantages
1. It is low in price because of fewer components and simple construction.
2. Easy to operate.
3. It doesn’t require any separate control mechanism like clutch pedal etc.
4. It requires less maintenance.
Disadvantages
1. Power transmission is limited due to slippage of shoes.
2.It can not be used to transmit a high amount of torque.
3. There will always be a power loss due to friction and slipping.
4. Overheating problem due to quick engagement during running conditions.

Why Do you need a centrifugal clutch?

A centrifugal clutch can be useful for a range of engine driven devices with high starting inertia. The speed at which the mechanically driven shaft engages can be controlled by using this type of clutch between the drive and the driven device. This allows the operator to operate the engine at a specified speed without having to operate the equipment, thus allowing the engine to reach its optimum torque before the load is experienced.

How Centrifugal Clutch Works?

In the centrifugal clutch, the driving member rotates on the movement of the engine crankshaft. When engine speed reaches specified rpm it generates enough centrifugal force on the brake shoes. It pushes the shoes outward of the center, which results in the connection of brake shoes to the friction lining of the driven member, it generates friction and transmits the power.

What is a Noram Centrifugal Clutch?

Noram Centrifugal Clutch is designed to allow safe, no-load, quiet starting of power tools. Noram clutches help reduce vibration, peak torque for more efficient engine performance, and offer overload protection for operator and equipment safety.

What is a Hilliard Centrifugal Clutch?

Hilliard centrifugal clutch delivers automatic, gradual, cushioned engagement over a speed range on high-inertia loads. This smooths out and reduces the starting current surge. They protect against overload by absorbing shock, limiting torque and eliminating torsional resonance.

Centrifugal Clutch Used In Which Vehicle?

This clutch is used in an automatic transmission system. Centrifugal clutch is used in scooters, mopeds, and go-karts.

What Is Semi-Centrifugal Clutch?

In the Semi-centrifugal clutch, the clutch springs are designed to transmit the torque at normal speeds, while for higher speeds, centrifugal force helps in torque transmission. The clutch pedal is used in the Semi-centrifugal clutch.
