Introduction to HTD Pulleys

HTD (High Torque Drive) pulleys are an essential component in the mechanical operation of scooters. These pulleys are precision-engineered to provide efficient power transmission, ensuring smooth and reliable performance.

What is an HTD Pulley?

An HTD pulley is a specialized component designed to work with HTD belts. These pulleys have a distinct tooth profile that engages with the corresponding belt teeth, creating a positive engagement and preventing slippage.

HTD pulleys are known for their high efficiency in power transmission. This efficiency is crucial for scooters, where every bit of power needs to be utilized effectively.


The materials used in HTD pulleys are typically robust and wear-resistant, ensuring a long lifespan and reduced maintenance costs.


HTD pulleys are manufactured with high precision, ensuring perfect alignment and engagement with the belt. This reduces the risk of mechanical failures.


These pulleys are compatible with a variety of HTD belts, making them versatile components for different scooter models.

Load Capacity

HTD pulleys can handle significant loads, making them ideal for high-torque applications such as scooters.

What is the Minimum Pulley Size for HTD 5M?

The minimum pulley size for HTD 5M varies depending on specific requirements and belt characteristics.

Number of Teeth

The minimum number of teeth for an HTD 5M pulley typically ranges from 12 to 16. This range ensures adequate engagement with the belt while maintaining the pulley¡¯s structural integrity.

Pitch Diameter

Pitch diameter is a critical factor in determining the minimum pulley size. For HTD 5M, the pitch diameter should be calculated based on the number of teeth and the belt pitch.

Application Requirements

The specific application requirements, such as torque and speed, will influence the minimum pulley size. For scooters, these requirements must be carefully evaluated.

What is the Difference Between GT and HTD Belts?

GT and HTD belts differ in their design and application, despite having similar functionalities.

Tooth Profile

GT belts have a curvilinear tooth profile, whereas HTD belts have a trapezoidal tooth profile. This difference affects the engagement and load distribution.

Load Capacity

GT belts typically offer higher load capacities and better performance in high-torque applications compared to HTD belts.

Noise Reduction

GT belts are designed to operate more quietly than HTD belts, making them suitable for applications where noise reduction is critical.

Choosing the Right HTD Pulley

Selecting or customizing the appropriate HTD pulley involves several key parameters.

Number of Teeth

The number of teeth on the pulley affects the engagement with the belt and the overall performance. It’s essential to match this with the belt¡¯s specifications.


Choosing the right material for the pulley can influence its durability and performance under different operating conditions.

Bore Size

The bore size must fit the scooter¡¯s shaft perfectly to ensure proper alignment and power transmission.


Matching the pulley’s width with the belt¡¯s width is crucial for optimal performance and to prevent misalignment or slippage.


Incorporating flanges into the pulley design can help to retain the belt and maintain proper tracking, reducing the risk of belt derailment.
