Sandvik Cone Crusher pinion shaft

The pinion shaft of the cone crusher is an important part in the drive motor assembly. The following is a detailed introduction and general manufacturing process of the pinion shaft of the cone crusher: Detailed Introduction: The pinion shaft is set on the cone crusher and connected to the output end of the drive motor through a coupling. It plays a role in transmitting power and transfers the rotational motion of the drive motor to other parts of the crusher to achieve the crushing operation. Manufacturing Process: 1. Material Selection: According to the working requirements and load conditions of the cone crusher, select appropriate materials, which usually need to have high strength, wear resistance, and good mechanical properties. 2. Forging or rolling: Forge or roll the raw materials to improve the material's microstructure and properties. 3. Rough machining: Use equipment such as lathes for preliminary turning processing to make it close to the final shape and size, including turning the outer circle and end faces. 4. Milling processing: If there are keyways or other features on the pinion shaft that need to be processed, perform corresponding milling processing. 5. Heat treatment: Conduct appropriate heat treatment processes such as quenching and tempering to improve the hardness, strength, and wear resistance of the pinion shaft. 6. Fine turning processing: Perform fine turning on the pinion shaft to achieve higher dimensional accuracy and surface finish. 7. Hobbing or gear shaping: According to the design requirements of the pinion, use a hobbing machine or gear shaping machine to perform gear tooth processing to create accurate gear teeth. 8. Grinding processing (if necessary): Grind the tooth surface to further improve the tooth profile accuracy and surface quality. 9. Flaw detection: Use non-destructive flaw detection methods such as ultrasonic flaw detection to detect whether there are internal defects in the pinion shaft. 10. Surface treatment (such as rust prevention treatment): According to the use environment and requirements, perform corresponding surface treatment to protect the pinion shaft and extend its service life. In the actual manufacturing process, the specific process steps and parameters may vary depending on the manufacturer, equipment conditions, and product requirements. At the same time, to ensure the quality and performance of the pinion shaft, it is also necessary to strictly control the machining accuracy and quality of each process and conduct necessary inspections and tests. The referenced patent document also mentions the installation process of the pinion shaft, as follows: First, install a spacer sleeve on the pinion shaft; then heat the hub with a through hole; then install the hub on the pinion shaft; then install a retaining gasket, and the bolts of the retaining gasket must be tightened so that the retaining gasket is connected to the hub; then loosely install the hub and taper sleeve on the motor shaft so that it can be adjusted; finally, install one of the flexible elements on the hub and tighten the self-locking bolts. In addition, the flexible element of the coupling is made of special polyurethane containing additives, which can ensure the best performance and minimize the impact of aging. At the same time, setting a speed sensor on the pinion shaft can play a good role in transmitting speed signals and is convenient for control. It should be noted that for different models and specifications of cone crushers, the design and manufacturing process of their pinion shafts may be different. In practical applications, targeted design and manufacturing need to be carried out according to the specific crusher model and working conditions to meet the normal operation and production requirements of the equipment.
