Cone Crusher Gear Oil Pressure and Clearance Adjustment Method

1. Principle of cone crusher gear oil pressure adjustment

Cone crusher is a commonly used mining equipment, widely used in mining, chemical industry, road and bridge construction, construction and other industries. In order to ensure the normal operation of the cone crusher, its gear oil pressure needs to be properly adjusted. The gear oil pump delivers hydraulic oil to various parts to lubricate and cool the gears, thereby ensuring the stability and durability of the cone crusher.

2. Steps for cone crusher gear oil pressure adjustment

(1. Before adjusting the cone crusher gear oil pressure, you first need to turn off the power supply and oil circuit valve to ensure safety.

(2. The oil pressure can be adjusted by increasing or decreasing the displacement of the oil pump. Generally, the larger the oil pump displacement, the higher the oil pressure. Make appropriate adjustments according to actual conditions.

(3. Adjust the pressure reducing valve to the appropriate position to meet the required oil pressure.

(4. After adjusting the cone crusher gear oil pressure, it is necessary to test whether the oil pressure is appropriate. The test process needs to last for a period of time to ensure that the oil pressure is stable.

(5. After the test is completed, according to According to actual needs, make appropriate adjustments and lock the valve to ensure that there is no misoperation.

3. Cone crusher gear clearance adjustment method

(1. If possible, the large gear counterweight side on the eccentric sleeve should be placed directly above the small gear.

(2. Use a crowbar or other means to pull the small gear toward the drive side so that the thrust end face of the small gear is close to the end face of the bearing sleeve on the inner side of the drive shaft frame. Note: Before measuring, the belt or flexible coupling must be loosened.

(3. Slightly rotate the drive shaft until the large gear teeth are in the plumb position.

(4. Use a jack or crowbar to press the eccentric sleeve toward the small gear side to eliminate the eccentric sleeve of the cone crusher and the frame lining The clearance of the sleeve makes the large and small gears close to each other. Use the jack to push the small gear horizontally. The force of the jack and the pry bar should only be enough to eliminate the clearance, and the eccentric sleeve should not be tilted.

(5. Keep the large gear in the above position for measurement. The clearance value should be measured at three equal points, and then the average value should be taken. The average value should meet the above requirements.

IV. Matters needing attention

(1. When adjusting the oil pressure of the cone crusher gear, it is necessary to check whether the oil circuit and oil pump are normal to ensure the safety of the adjustment process.

(2. When adjusting the oil pressure, it is necessary to proceed step by step, and do not be impatient to avoid wrong results.

(3. The oil pressure adjustment should be based on According to the actual situation, it cannot be adjusted blindly, otherwise it may affect the normal operation of the equipment.

(4. During the test, it needs to continue for a period of time to ensure the accuracy of the test results.

(5. After the adjustment is completed, the valve needs to be locked to avoid losses caused by misoperation.

[Conclusion]

The adjustment of the gear oil pressure of the cone crusher is an important guarantee for the normal operation of the cone crusher. Through the introduction of Xin Gaonai Heavy Industry, we understand the principles, methods and matters needing attention of the gear oil pressure and clearance adjustment of the cone crusher. As long as the correct steps are followed, the normal operation and long-term use of the cone crusher can be guaranteed, thereby improving production efficiency.
