Introduction to Road Sweeper Machine

Road cleanliness is essential for maintaining hygiene, ensuring safety, and enhancing the overall
appearance of urban and rural areas. This project presents a manual road sweeper machine designed
to efficiently remove dust, debris, and small particles from roads and pavements. The machine is
constructed using two bicycle wheels and two caster wheels, ensuring smooth movement and
maneuverability.

A key feature of this design is the combination of a chain drive and a gear drive on each side, which
efficiently transmits power to the horizontal cylindrical brush. As the machine moves forward, the
brush rotates, sweeping debris toward a designated collection area. This mechanism eliminates the
need for external power sources, making it an eco-friendly and cost-effective solution for road
cleaning.

This innovative and simple road sweeper offers an effective alternative to traditional sweeping
methods, reducing manual effort while increasing efficiency. It is particularly suitable for cleaning
streets, sidewalks, parks, and other public spaces with minimal maintenance requirements.

Chain Drive Mechanism in the Manual Eco-Friendly Road Sweeper Machine

1. Introduction to Chain Drive

A chain drive is a mechanical power transmission system that transfers motion and force from one
rotating element (such as a wheel or motor) to another using a chain. It is widely used in bicycles,
motorcycles, and industrial machinery due to its efficiency, durability, and ability to transmit power
over long distances.

2. Chain Drive in the Road Sweeper Machine

In the Manual Eco-Friendly Road Sweeper Machine, the chain drive mechanism is used to transmit
rotational motion from the bicycle wheels to the cylindrical brush, ensuring efficient sweeping action.

3. Components of the Chain Drive System

The chain drive system in the sweeper consists of the following components:

1. Driving Sprocket (Input) – Mounted on the axle of the bicycle wheel, which acts as the power
source.

2. Roller Chain – A continuous loop of metal links that transfers motion from the driving sprocket
to the driven sprocket.

3. Driven Sprocket (Output) – Connected to the cylindrical brush, which rotates when power is
transmitted.

4. Tensioner (Optional) – A mechanism that maintains proper chain tension and prevents slippage.

4. Working Principle of the Chain Drive

 When the operator pushes the machine, the bicycle wheels rotate.

 The rotation of the wheel turns the driving sprocket, which is attached to the wheel axle.

 The roller chain transmits this rotational motion to the driven sprocket, which is connected to
the cylindrical brush.

 As the driven sprocket rotates, the cylindrical brush spins, sweeping dust and debris from the
road surface.

5. Advantages of Using a Chain Drive in the Sweeper

✔ Efficient Power Transmission – Provides a direct and reliable transfer of motion with minimal energy
loss.
✔ Durability – Strong and long-lasting, capable of withstanding rough road conditions.
✔ Low Maintenance – Requires occasional lubrication but has fewer complex parts than belt drives.
✔ Cost-Effective – Affordable compared to other power transmission systems.

8
✔ Compact and Lightweight – Does not add excessive weight to the machine, making it easy to
maneuver.

Gear Drive: An Overview

9
A gear drive is a mechanical system used to transmit power and motion between rotating shafts using
gears. It is widely used in industrial machines, automobiles, robotics, and various mechanical systems
where precise motion and power transmission are required.

Components of a Gear Drive

1. Driver Gear (Input Gear) – The gear that receives power from the prime mover (e.g., motor,
engine).

2. Driven Gear (Output Gear) – The gear that receives motion from the driver gear.

3. Intermediate Gear (Idler, if present) – A gear between the driver and driven gear that changes
the direction of rotation without altering the speed ratio.

4. Shafts – Rotating elements on which gears are mounted.

5. Bearings and Housing – Support the shafts and ensure smooth rotation.

6. Lubrication System – Reduces friction and wear between meshing teeth.

Types of Gear Drives

1. Spur Gear Drive – Uses straight teeth parallel to the shaft. Simple and efficient but noisy at high
speeds.

2. Helical Gear Drive – Teeth are cut at an angle, providing smoother and quieter operation.

3. Bevel Gear Drive – Transmits power between shafts at an angle (usually 90°).

4. Worm Gear Drive – Consists of a worm (screw) and a worm wheel. Provides high torque with a
compact design.

5. Rack and Pinion Drive – Converts rotational motion into linear motion. Used in steering systems.

6. Planetary Gear Drive – Uses multiple gears (sun, planet, ring) for compact, high-torque
applications (e.g., automatic transmissions).

Working Principle

 When the driver gear rotates, its teeth mesh with the driven gear, causing it to rotate.

 The speed and torque depend on the gear ratio:

Gear Ratio=Number of teeth on driven gearNumber of teeth on driver gear\text{Gear Ratio} = \

10
 frac{\text{Number of teeth on driven gear}}{\text{Number of teeth on driver
gear}}Gear Ratio=Number of teeth on driver gearNumber of teeth on driven gear

 If the driven gear has more teeth than the driver gear, speed decreases, and torque increases
(and vice versa).

Advantages of Gear Drives

✔ High efficiency in power transmission.

✔ Provides precise speed and torque control.
✔ Works in both high-speed and high-load applications.
✔ More compact than belt and chain drives.

Disadvantages of Gear Drives

✘ Requires lubrication and maintenance.

✘ More expensive to manufacture compared to belt drives.
✘ Generates noise and vibrations at high speeds.
