#140-2 1-3/4″ Pitch QD Sprocket

#140-2 1-3/4" Pitch QD Sprocket Specifications

QD Sprocket No.140-2 Double Type is a type of sprocket that is widely used in power transmission systems. A sprocket is a wheel with teeth that meshes with a chain or track.

Definition and Basic Structure of QD Sprocket

QD Sprocket stands for Quick Detachable Sprocket. As the name suggests, it is designed for easy installation and removal. The basic structure of a QD Sprocket consists of two parts: the sprocket and the QD bushing. The sprocket has teeth that mesh with the chain, while the QD bushing is a split bushing that provides a tight fit between the sprocket and the shaft.

Features and Functions of QD Bushing

• Easy Installation: QD bushings are designed for easy installation and removal. They can be installed or removed quickly without the need for special tools.
• High Load Capacity: QD bushings have a high load capacity, which allows them to withstand heavy loads without deformation or failure.
• Standardized Design: QD bushings have a standardized design that allows them to be used with different sizes of shafts and sprockets.
• Compact Design: QD bushings have a compact design that allows them to be used in tight spaces.
• Low Maintenance Cost: QD bushings require minimal maintenance, which reduces maintenance costs.

QD bushings are essential components of QD sprockets. They provide a secure fit between the sprocket and the shaft, which ensures smooth and efficient power transmission.

Installation and Removal Process of QD Bushing

The installation and removal process of QD bushing involves the following steps:

1. Prepare Tools and Materials: Gather all the tools and materials needed for the installation or removal of the QD bushing.
2. Clean Shaft and Sprocket Surface: Clean the shaft and sprocket surface to remove any dirt or debris that may interfere with the installation of the QD bushing.
3. Position Sprocket: Position the sprocket on the shaft and align the keyway with the key.
4. Install QD Bushing: Slide the QD bushing onto the shaft and tighten the screws to secure it in place.
5. Secure Sprocket: Slide the sprocket onto the QD bushing and tighten the screws to secure it in place.
6. Check: Check the alignment of the sprocket and the QD bushing to ensure smooth and efficient power transmission.

The installation and removal process of QD bushing is simple and can be completed quickly without the need for special tools or skills.

Manufacturing Process of QD Sprocket

The manufacturing process of QD sprocket involves the following steps:

1. Prepare Raw Materials: Prepare raw materials such as steel or cast iron.
2. Cutting: Cut the raw materials into the desired sizes and shapes.
3. Forging or Casting: Forge or cast the raw materials into the shape of the sprocket.
4. Machining: Machine the sprocket to the desired dimensions and finish.
5. Teeth Cutting: Cut the teeth on the sprocket using a hob or shaper.
6. Heat Treatment: Heat-treat the sprocket to increase its hardness and strength.
7. Surface Treatment: Treat the surface of the sprocket to improve its corrosion resistance and appearance.
8. Quality Inspection: Inspect the quality of the sprocket to ensure that it meets the required specifications and standards.

The manufacturing process of QD sprocket is complex and requires advanced technology and equipment. However, it ensures that QD sprockets are of high quality and can meet the demanding requirements of power transmission systems.
