Description

Gear box with efficient heat dissipation function Technical Field The utility model relates to the technical field of mechanical transmission equipment, in particular to a gear box with an efficient heat dissipation function. Background Currently, in the field of industrial transmissions, gearboxes are key components widely used in various mechanical devices. When the equipment is operated under high load conditions, the temperature of the lubricating oil in the gear box can be increased remarkably, which not only affects the lubricating effect, but also can cause problems of ageing of sealing elements, aggravation of component wear and the like, thereby reducing the service life and the operation efficiency of the equipment. In the related art, a traditional gear box mainly relies on natural heat dissipation or a simple air cooling device to perform cooling treatment. However, because the heat dissipation efficiency of these methods is low, the cooling requirement under the high-load working condition cannot be met, and therefore, in practical application, the situation that the lubrication fails due to too high oil temperature often occurs.
