#120-2 1-1/2" Pitch QD Sprocket Specifications

Basic Concept of QD Sprocket

The QD sprocket is a type of sprocket that utilizes a taper-lock bushing for mounting onto a shaft. The bushing fits within the sprocket hub, and the sprocket is affixed to the shaft using a set screw. This design simplifies the installation and removal process of the sprocket, eliminating the necessity for a keyway or other fastening devices.

QD Sprocket Definition and Structure

The QD sprocket comprises a sprocket body and a taper-lock bushing. The sprocket body, crafted from high-quality steel, is designed to transmit power from a driving shaft to a driven shaft. The taper-lock bushing, made of high-strength steel, provides a firm grip on the shaft, ensuring a secure connection between the sprocket and the shaft.

QD Bushing Features and Functions

The QD bushing boasts several key features and functions that make it a preferred choice for power transmission systems, including:

• Easy installation: The QD bushing can be installed onto the shaft without requiring special tools or equipment.
• High load capacity: Capable of handling substantial torque loads, the QD bushing is perfect for heavy-duty applications.
• Standardized design: Designed to meet industry standards, the QD bushing allows for straightforward replacement or upgrades of existing bushings.
• Compact design: With a small footprint, the QD bushing is suitable for use in confined spaces.
• Low maintenance cost: The QD bushing needs little to no maintenance, thereby reducing downtime and overall maintenance expenses.

QD Bushing Installation and Removal Process

The installation and removal of the QD bushing can be carried out easily by following these steps:

• Prepare tools and materials: Collect all necessary tools and materials, including the sprocket, taper-lock bushing, set screws, and a torque wrench.
• Clean shaft and sprocket surface: Ensure that both the shaft and sprocket surfaces are clean for a secure connection between the bushing and the shaft.
• Position sprocket: Place the sprocket onto the shaft at the desired location.
• Install QD bushing: Insert the QD bushing into the sprocket hub and tighten the set screws to the manufacturer's recommended torque.
• Secure sprocket: Ensure the sprocket is securely fitted onto the shaft, checking for proper alignment.
• Check: Verify that the installation is secure and the sprocket is correctly aligned.

QD Sprocket Manufacturing Process

The process of manufacturing the QD sprocket involves several steps:

• Prepare raw materials: Choose and prepare high-quality steel for sprocket production.
• Cut material: Employ cutting tools to shape the steel into the required dimensions.
• Forge or cast: Utilize forging or casting methods to form the sprocket into its final shape.
• Machining: Use precision machining tools to finish the sprocket and create the teeth profile.
• Rolling: Implement sprocket rolling machines to finalize the teeth profile.
• Heat treatment: Heat-treat the sprocket to enhance its strength and durability.
• Surface treatment: Apply a protective surface treatment to guard against corrosion and wear.
• Quality control: Execute a series of quality control tests to confirm that the sprocket meets industry standards.

Introduction

QD Sprocket No.120-2 Double Type is a type of sprocket used in power transmission systems. A sprocket is a profiled wheel with teeth that mesh with a chain, track, or other perforated or indented material. It is commonly used in bicycles, motorcycles, and industrial machinery.

Basic Concept of QD Sprocket

The QD sprocket is a type of sprocket that uses a taper-lock bushing to mount the sprocket onto the shaft. The bushing is mounted inside the sprocket hub, and the sprocket is then mounted onto the shaft with a set screw. This design allows for easy installation and removal of the sprocket without the need for a keyway or other fastening mechanism.

QD Sprocket Definition and Structure

The QD sprocket consists of a sprocket body and a taper-lock bushing. The sprocket body is made of high-quality steel and is designed to transmit power from a driving shaft to a driven shaft. The taper-lock bushing is made of a high-strength steel and is designed to grip the shaft tightly, providing a secure connection between the sprocket and the shaft.
