Description

Power-free oil supply device of cone crusher

Technical field

The invention relates to a power-free oil supply device of a cone crusher, which belongs to the technical field of mechanical lubrication.

Background technique

During the operation of the machine, the parts that contact and move relatively need to use lubricants to reduce the friction of the contact parts to extend the service life of the equipment. The crusher is an indispensable machine for mining operations. It is used to crush ore. According to the crushing method and mechanical structural characteristics, it can be divided into six categories, including jaw crusher, cone crusher, roller crusher, impact crusher, impact crusher, hammer crusher, of which jaw type Crushers, cone crushers, roller crushers mainly crush materials by squeezing force, impact crushers, impact crushers, hammer crushers mainly crush materials by impact force.

Among them, the cone crusher is widely used in mining machinery, mainly used to crush some medium and medium hardness ores and rocks. When it is necessary to control the size of crushed material particles or when encountering hard materials such as iron blocks, it is necessary to timely control the up and down movement of the main shaft to adjust the gap between the moving cone lining plate and the static cone lining plate; hydraulic pressure developed in recent years The cone crusher is adjusted by the hydraulic system to move the spindle up and down compared with the previous use of mechanical transmission or manual operation, which greatly improves the work efficiency. The effective crushing of the mineral material by the cone crusher is driven by the high-speed operation of the drive shaft The work piece is broken, so the lubrication and cooling of the drive shaft is extremely important. However, the hydraulic system in the prior art still has the problems of low sensitivity, low response speed, and low sealing of the oil circuit. The bearing load of the moving parts of the cone crusher is large, so the reasonable lubrication system directly affects the working efficiency of the cone crusher and the service life of the parts.

Currently, solid lubricating oil or liquid lubricating oil is usually used to lubricate the drive shaft. However, it is very inconvenient to disassemble the machine to apply the solid lubricating oil during use. The mechanical disassembly is troublesome, and frequent manual replacement is required to increase the workload. Solid lubrication The oil application is easy to be uneven, and can only be partially lubricated, and cannot be circulated. The temperature rises quickly under the action of friction. It needs to be stopped and cooled, which seriously affects the efficiency of the machine. Liquid oil lubrication can achieve circulation, and the oil supply and oil change are convenient, but the liquid Lubricating oil needs to provide additional power for pumping, consumes energy and provides necessary assembly space.
