HTD Pulley for Textiles Machinery

What is an HTD Pulley?

HTD pulley

High Torque Drive

HTD stands for High Torque Drive. An HTD pulley is designed to deliver high torque transmission from the motor to the driven machinery, which is essential for heavy textile machinery operations.

Synchronous Drive

The HTD pulley ensures synchronous drive between the motor and the machinery, which means the pulley’s teeth engage precisely with the corresponding belt teeth, ensuring no slippage and maintaining timing accuracy.

Profile Design

HTD pulleys have a unique curvilinear tooth profile that allows for better load distribution and reduces the risk of belt wear and tear, thus enhancing the lifespan of the textile machinery.

Material and Durability

Typically made from robust materials such as steel or aluminum, HTD pulleys are designed to withstand high operational stress and provide long-term durability, which is essential for the continuous operation of textile machinery.

Variety of Sizes

HTD pulleys come in various sizes and pitches to fit different machinery requirements, offering flexibility in design and application within the textiles industry.

What is the Minimum Pulley Size for HTD 5M?

Understanding HTD 5M

The HTD 5M pulley has a 5mm pitch between the teeth, making it suitable for precise and high-torque applications in textile machinery.

Minimum Number of Teeth

The minimum number of teeth for an HTD 5M pulley is typically 12, which ensures adequate engagement with the belt while maintaining smooth operation.

Diameter Consideration

The diameter of the smallest HTD 5M pulley is approximately 19.1mm. This ensures that the pulley can handle the required torque without compromising the structural integrity of the belt.

Load Capacity

The minimum size is also influenced by the load capacity requirements of the textile machinery. Smaller pulleys may be suitable for less demanding applications, while larger pulleys may be needed for higher load requirements.

Application Specificity

The specific application within textile machinery will dictate the exact minimum size, with considerations such as speed, torque, and operational environment playing critical roles.

What is the Difference Between GT and HTD Belts?

Tooth Profile

HTD belts have a curvilinear tooth profile, while GT belts have a modified curvilinear profile. The GT profile allows for improved stress distribution and reduced backlash.

Load Capacity

GT belts generally offer higher load capacities due to their improved tooth engagement and distribution of forces, making them suitable for more demanding applications.


GT belts provide higher precision and less backlash compared to HTD belts, which is critical in applications requiring exact timing and positioning.


Both belts are durable, but GT belts often have a longer operational life due to their optimized tooth profile and material composition.


GT belts may be more expensive than HTD belts due to their advanced design and performance characteristics, but the cost can be justified by their superior performance and longevity.

How to Select or Customize the Right HTD Pulley

HTD pulley

Determine Torque Requirements

First, determine the torque requirements of your textile machinery. This involves calculating the operational load and ensuring the pulley can handle the specified torque without failure.

Evaluate Speed Specifications

Check the speed specifications of the machinery. The HTD pulley should match the operational speed requirements to ensure efficiency and prevent slippage.

Material Selection

Choose the appropriate material for the pulley based on the operational environment. Options include steel, aluminum, and composite materials, each offering different benefits in terms of durability and weight.

Pitch and Size

Select the pitch and size of the pulley according to the belt being used and the machinery’s design constraints. Ensure compatibility with the HTD belt to achieve optimal performance.

Customization Options

Consider any customization options available, such as coatings or special treatments, to enhance the pulley¡¯s performance in specific operational conditions. Customization can lead to improved efficiency and longevity.
