55mm Shaft Pulley

The 55mm shaft pulley is designed to connect directly to a 3-phase electric motor with a capacity of 30kW (40Hp), facilitating power transmission from the motor to other parts of the system. This device is widely used in many industries thanks to its superior durability, good load-bearing capacity, and stable operation in harsh conditions.

Overall design of the 55mm shaft pulley

This pulley is made from high-strength materials such as cast iron, steel, or iron, enhancing wear resistance and heavy load capacity. With a sturdy structure and simple design, this pulley is easy to install and maintain, saving time and costs for operational activities.

Structure of the 55mm pulley

The 55mm pulley has a basic structure consisting of 3 main parts: the pulley wheel (with an outer diameter of 55mm), the shaft bore (for mounting to the motor), and the bearing to reduce friction. Depending on the design, the pulley can be a smooth groove type (used for V-belts) or a timing belt pulley with notched grooves for synchronous power transmission.

Detailed structure of the 55mm pulley includes:

• Pulley wheel: Usually made of cast iron, aluminum, steel, or hard plastic. The outer diameter of the wheel is 55mm. The surface is designed with V-grooves, trapezoidal grooves, or timing grooves to mesh with the belt.
• Shaft bore and pin: The center part located between the pulley used to connect directly to the motor shaft or machine shaft. This size is precisely drilled according to the actual shaft to ensure concentricity during operation.
• Bearing and keyway: In types of pulleys requiring flexibility, bearings are installed in the shaft bore to help the pulley rotate smoothly and minimize friction. The keyway inside the shaft bore helps fix the pulley to prevent slipping when the motor rotates with high torque.

Technical specifications of the 55mm pulley

The 55mm pulley is designed to be installed on a 55mm motor shaft, suitable for many industrial belt-driven systems. Below are the basic technical specifications of the product.

Applications of the 55mm shaft pulley

The 55mm shaft pulley is widely applied in many industrial fields thanks to its powerful and stable transmission capacity. Typical applications include:

• The 55mm shaft pulley converts and transmits motion and force from the electric motor to other machinery parts in industrial systems, making operation smooth and efficient.
• The pulley is also used in conveyor systems, cranes, and lifting equipment in construction, helping to move materials quickly and efficiently from one place to another.

The 55mm shaft pulley is a transmission accessory suitable for systems using a 55mm motor shaft, well-meeting requirements for durability, load capacity, and stable power transmission.
