Description
Technical Field
The utility model relates to a shaft coupling technical field, more specifically relates to a novel heavy load mining dump truck power spring coupling.
Background
The elastic coupling is used as a connecting part of the engine and the PTO, transmits the torque of the engine through the friction damping action of the rubber element, and plays a role in buffering and shock absorption under the elastic damping action of the rubber element. The elastic deformation of the elastic element can compensate the deflection and displacement between the two shafts, and the elastic connection improves the working performance of the transmission system.
The split elastic body 7 of the split elastic coupling (shown in figure 3) has extremely high elasticity under the working conditions of engine load and low rotating speed, and can remove resonance in a low rotating speed range and eliminate gear knocking. The structure can be used for small-tonnage vehicle types, but when large-tonnage vehicle types are used, particularly under the condition that overload generally exists on the site, the elastic element is extremely easy to damage due to no overload protection. Generally, the split coupling is too rigid and is only suitable for light load connection. Therefore, a novel power elastic coupling for the heavy-load mining dump truck is needed to make up for the industrial vacancy.
