What is the material and function of the cone crusher main shaft sleeve?

October 26, 2024

The material of the cone crusher main shaft sleeve is mainly high-lead bronze. High-lead bronze has high wear resistance and corrosion resistance, can withstand high pressure and friction, and ensure that the main shaft sleeve remains stable in long-term use.

Function

Reduce friction and wear: The main shaft sleeve can reduce the sliding friction of the equipment during operation, reduce power loss, and thus extend the service life of the equipment.

Protect steel parts: Effectively protect the steel parts in contact with it from wear. When the copper parts are worn, they are easy to replace, reducing repair and maintenance costs, and striving for higher equipment utilization.

Improve equipment stability: The material and size requirements of the main shaft sleeve are high, especially the matching clearance between the bowl-shaped bearing bracket and the crushing wall is the most important technical difficulty. Selecting a bowl-shaped bearing with guaranteed material and processing size is the key to whether the equipment can operate normally.

Installation and maintenance

Preparation before installation: Clear the debris in the oil tank and oil hole, check whether the dust ring and oil ring are damaged or deformed, and check whether the processing surfaces are damaged. If there is any damage, repair it immediately.

‌Precautions during installation‌: The bowl-shaped bearing frame should fit tightly with the base, and use a feeler gauge to check the tightness of the horizontal contact surface. After installation, immediately cover the bowl-shaped tile with a cover plate, and then remove the cover plate when installing the crushing cone. During installation, pay attention to protecting the water inlet pipe, drainage channel, oil retaining ring, and dustproof ring to avoid damage during installation‌.
