[0002] A crusher is an industrial device mainly used to crush, break or cut large solid raw materials by mechanical force for subsequent processing or reuse. Such devices are widely used in many industrial and construction fields. Crushers are usually driven by electric motors or diesel engines and use working components such as high-speed rotating blades, hammers or pressure rollers to impact, break or compress raw materials and decompose them into smaller particles or lumps of materials.

[0003] As an important industrial device, the crusher not only improves the utilization rate and reuse rate of raw materials, but also plays an important role in resource recovery and environmental protection. It is one of the indispensable important devices in modern industrial production. The crushing rollers of the crusher rotate through gear meshing, and the gears need a lubrication device for lubrication. However, most of the existing lubrication devices use static lubrication.
