Description

Technical Field

[0001] This utility model relates to the field of decimal slider technology, and in particular to a large decimal slider with high cold resistance and long life. Background Technology

[0002] The universal joint slider is the core load-bearing component of the universal joint transmission system. Large universal joint sliders are mostly used in heavy equipment. Their cold resistance and service life directly determine the reliability of the equipment. In extremely cold regions, the performance defects of the slider can lead to equipment downtime, soaring maintenance costs, and even safety accidents.

[0003] To improve the service life of existing large decant sliders, polyurea grease is usually applied manually to the friction area of ​​the slider for lubrication. However, due to the excellent low-temperature stability of polyurea grease, existing technologies are not suitable for temporarily storing a certain amount of polyurea grease, resulting in low practicality.

[0004] To address this, we propose a large decabyte slider with high cold resistance and long lifespan. Utility Model Content
