SHAFT MANUFACTURING PROCESS:

The main steps involved in manufacturing a shaft are machining, turning, finishing and packing.The manufacturing process begins with roughing, which essentially cuts the shaft into accurate small pieces. During the turning process, the shaft pieces forms the final shape. A milling machine then transforms the pieces into the desired shape. Finally, the package is delivered to the customer.

SHAFT MACHINING PROCESS:

The shaft machining process produces precise and accurate shapes on a metal shaft. Shaft machining is necessary for a support roller to function correctly and efficiently.

Shaft machining process are as follows:

Design: The first step is to create a design for the shaft in the CAD/CAM software. Use this design to create the paths for the tools and cutting areas for the CNC machine. Also set the specifications of the shaft, including length, diameter, and other necessary specifications.

Set up the machine: set up the machine (CNC VTL) with the correct fittings and tools for the shaft. This includes a tool chuck or joint to hold the workpiece, cutting tools for roughing and finishing, and coolant to wet and cool the cutting process.

Grooving process: Horizontal boring machines are used to drill end faces, center holes, and tapped holes. A cutting tool is used to enlarge an existing hole or bore in the shaft

Drilling process: Drilling is a common process in CNC VTL (vertical turning lathe) machining to drill or make holes in a workpiece. Usually, a drill, a cutting instrument with a pointed tip, is placed on the workpiece, which rotates rapidly.

Mounting: Once the machine is set up, mount the support roller on a lathe or other machining tool  to form the shaft. The shaft is securely fastened to the tool, making sure that it is properly aligned and positioned.

Turning process: Turning uses a cutting tool to remove material from the shaft.

Shaft Machining and Inspection Process

Roughing process: Roughing is the process of using a roughing tool to remove the bulk of the material from the workpiece. A roughing tool removes excess material from the workpiece while avoiding collisions.

Chamfering process: In the chamfering process, the edge of a workpiece, such as a shaft, is cut or turned to form a specific angle or shape. Chamfering is usually done on a CNC VTL (vertical lathe) with special cutters to make a precise cut on certain edges.

Finishing: After roughing, finishing tools produce a smooth surface on the workpiece. Grinding, polishing, and buffing are various methods to finish the shaft. This ensures that the surface of the shaft is clean and free of defects.

Inspection and Quality Control: The last or final step is to test the shaft to ensure that it meets the standards set by the manufacturer. This involves checking the diameter, length, and any other specific requirements identified during the preliminary test. Quality control measures are necessary to ensure that the support roller operates efficiently.

FEATURES OF SUPPORT ROLLER SHAFT:

• The support shaft holds the substantial weight of the rotary kiln.
• Robust and powerful tool.
• Proper alignment and machining is necessary to ensure the smooth rotation of the kiln.
• Ensures effective and secure functioning.
• To prevent possible safety risks and guarantee the long-term dependability and performance of the kiln, proper maintenance and routine inspection of the support shaft is crucial.

• Protection: The bearing housing guards against contamination of the bearings by dust, grime, and other foreign objects. Additionally, it aids in cooling down the heat produced by the revolving kiln and its bearings.
• Maintenance: The bearing housing has access panels or removable covers that make it simple to examine and lubricate the bearings. For the kiln to operate safely and effectively, routine upkeep is necessary.
• Heat resistance: The bearing housing needs to be able to endure the kiln’s potentially 1000°C-plus temperatures. To prevent deformation or failure under these harsh circumstances, the materials used to construct the housing must have great heat resistance.

4. ROTARY KILN SUPPORT ROLLER LABYRINTH RINGS:

The mechanical part known as kiln support rollers assembly with bearings and labyrinth rings is used to support and move a kiln, which is used in many fields to heat and dry materials.The roller supports the kiln, while the bearings allow the kiln to rotate.The labyrinth rings are sealing mechanisms that prevent dirt, dust, and other contaminants from entering the bearing, thereby extending its life.

5. ROTARY KILN SUPPORT ROLLER END PLATES:

A component that is located at the end of the rotary kiln support roller shaft is the end plate.

6. ROTARY KILN SUPPORT ROLLER END COVERS:

A component that covers the end of the support roller and gives the rotary kiln extra support and protection. The end cover uses high-strength steel or other sturdy materials to support both the weight of the kiln and the substance to process. End covers protect the ends of the support rollers in a rotary kiln. The end covers assist to prevent dust and debris from entering the roller bearings which can harm the roller bearings and reduce the duration of the roller.

To prevent deformation or failure under these harsh conditions, the materials used to create the end cover must have high heat resistance. For the kiln to run smoothly and effectively and to prevent early wear or support roller failure, proper alignment is necessary. To ensure that support roller end covers are in excellent shape and provide adequate protection to rolling bearings, it is important to inspect and maintain them regularly.
