Detailed Introduction to the Manufacturing Process of Gears for Cone Crushers The manufacturing process of gears for cone crushers typically includes the following steps: Design and Material Selection: Based on the working requirements and load conditions of the cone crusher, appropriate gear parameters such as the number of teeth, module, tooth width, etc., are designed. Simultaneously, materials with high strength, high wear resistance, and good processing performance are selected. Commonly used materials include alloy cast steel, etc.
1. Structure: Usually includes the gear body, with specific shapes and sizes of teeth on its outer surface. The tooth shape may be arc-shaped teeth to optimize the transmission performance. 2. Dimension Parameters: Such as the top angle and root angle of the teeth, the length and diameter of the shaft hole, the width and position of the keyway, etc. These parameters may vary depending on the specific crusher model and design requirements. 3. Material Selection: Generally, high-strength and wear-resistant materials are used to ensure that it can withstand large loads and wear in the working environment of the crusher. 4. Function: Engages with the large bevel gear to transfer the power of the motor to components such as the eccentric sleeve of the crusher, thereby driving the moving cone for rotary and swing motion to achieve the crushing of materials.
When designing the frame, it is necessary to consider the parts of the crusher frame where the highest stress occurs. Usually, the highest stress areas are near the flanges of the upper and lower frames. During the specific design, the crushing force can be decomposed into horizontal and vertical forces, and the intensity can be calculated at 5 MPa to obtain the magnitude of the crushing force. The magnitude of the force at the middle of the top bushing can also be obtained based on the moment balance. When calculating the strength of the flange section, the bending endurance limit can be calculated according to the symmetrical cyclic load to determine whether the section is safe. When calculating the strength of the lower frame, it is necessary to analyze the force situation of the lower frame flange before conducting the specific calculation. Among them, the calculation of the peripheral frame of the lower frame can calculate the maximum bending moment with the uniformly distributed load between the two ribs, and then determine whether the strength of each part of the lower frame is sufficient based on the previously obtained allowable stress for the symmetrical cycle.
Detailed Introduction: The hydraulic cylinder of the cone crusher is mainly used to achieve various functions, such as adjusting the size of the discharge opening, providing overload protection, and automatically discharging the crushed materials. By injecting or draining oil into the hydraulic cylinder through the oil pump, the main shaft can be moved, thereby changing the distance between the bowl liner and the crushing wall and achieving the adjustment of the discharge opening. When non-crushable foreign objects enter the crushing cavity or the machine is overloaded, the hydraulic cylinder can play the role of overload protection. Under the action of the hydraulic system, the hydraulic cylinder can make the moving cone automatically retreat, discharge the foreign objects from the discharge opening, and then automatically return to the normal working state.
It mainly functions to support and protect the pinion shaft. The pinion shaft meshes with the large gear to transfer power to the working components of the crusher to achieve the crushing operation. The pinion shaft housing needs to have sufficient strength and stiffness to withstand various loads and vibrations generated during the operation of the crusher. At the same time, it also needs to ensure the installation accuracy of the pinion shaft and good lubrication conditions to reduce wear and ensure the stable operation of the equipment.
This locking nut includes the locking nut body connected to the main shaft of the cone crusher through the threaded structure. Between the locking nut body and the crushing wall, a cutting ring is connected. Both the cutting ring and the locking nut body are provided with multiple pin holes, and internal threaded cylindrical pins are connected within the pin holes. One end of the pin is connected within the pin hole of the locking nut body, and the other end is connected within the pin hole of the cutting ring.
