Description

Technical Field

[0001] This invention relates to the field of automation control technology, and in particular to an automatic lubrication system and method for the high-speed shaft of a horizontal gearbox. Background Technology

[0002] Most existing stacker-reclaimer horizontal gearboxes with cantilever rotary gearboxes use passive lubrication gear pumps for their high-speed shafts. During operation, these pumps, under abnormal loads or after emergency braking of the cantilever rotation, can rapidly rotate in the opposite direction, generating significant torque and causing buffer failure. During prolonged, uncontrolled operation, the transmission shaft of the lubrication gear pump is highly susceptible to material fatigue deformation, leading to shaft breakage. Once the transmission shaft breaks, it cannot supply lubricating oil to the high-speed shaft and bearings, resulting in lubrication deficiency and equipment damage. Therefore, providing an automatic lubrication system and method for the high-speed shaft of a horizontal gearbox is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

This invention uses a cycloidal pinwheel lubricating oil pump instead of a traditional lubricating gear pump, and combines it with an automated control method to effectively avoid mechanical damage to the lubricating oil pump caused by frequent operation of the rotary gearbox. When the rotary gearbox is working, the lubricating oil pump changes the lubrication time to lubricate the bearings and gears in the gearbox, ensuring that the equipment operates effectively and smoothly.

[0128] In summary, this invention uses a detection unit to monitor the working status of the horizontal gearbox in real time. When the gearbox is in rotational operation, the cantilever rotation speed is monitored in real time. The control unit then controls the lubrication time of the high-speed shaft of the gearbox based on this cantilever rotation speed. This changes the traditional lubrication method, reduces the failure rate of the drive shaft, and improves the overall operational stability of the equipment. This invention offers advantages such as accuracy, automation, and a low failure rate.
