Can Plastic Gear Racks Be Used in Electric Vehicle Drivetrains?

Plastic Gear Rack is a type of rack made of plastic, used for transmitting power and motion. This article explores the viability of using plastic gear racks in electric vehicle drivetrains.

Structure and Materials

A. Composition of Plastic Rack

The basic structure of a Plastic Gear Rack consists of a series of teeth and gaps. These teeth are designed to mesh with the teeth of a pinion gear to convert rotational motion into linear motion or vice versa. The design of the rack and the profile of the teeth are crucial for efficient power transmission and motion control. Properly designed teeth profiles ensure smooth operation, reduce wear and tear, and enhance the overall efficiency of the system.

B. Commonly Used Plastic Materials

Common plastic materials used in gear racks include:

  • Polyamide (PA)
  • Polyethylene (PE)
  • Polypropylene (PP)

Plastic Gear Rack


1. Lightweight and Corrosion Resistance

Plastic gear racks are significantly lighter than their metal counterparts, which reduces the overall weight of the system and contributes to energy efficiency. Additionally, they are resistant to corrosion, making them ideal for environments where metal racks would degrade over time.

2. Low Noise and Low Friction

The inherent properties of plastic materials result in quieter operation and lower friction compared to metal gears, enhancing the comfort and efficiency of electric vehicle drivetrains.

3. Cost-Effective and Easy to Process

Plastic gear racks are often cheaper to produce and process compared to metal racks. The material can be molded into complex shapes without the need for extensive machining, reducing production costs.

4. Design Flexibility

Plastic offers greater design flexibility, allowing for the creation of customized gear racks tailored to specific applications and requirements.

5. Resistance to Chemicals and Moisture

Plastic materials are resistant to a wide range of chemicals and moisture, making them suitable for harsh industrial environments where exposure to corrosive substances is common.

6. Reduced Wear on Other Components

The softer nature of plastic reduces wear on meshing components, extending the lifespan of both the gear rack and the pinion gear.
