Description
Technical Field
The invention discloses an axle-hung traveling driving speed reducer of a large-axle-weight self-propelled metallurgical vehicle, relates to the technical field of driving speed reduction, and particularly relates to an axle-hung traveling driving speed reducer of a large-axle-weight self-propelled metallurgical vehicle with the axle weight of more than 40 tons.
Background
The large-axle-weight self-propelled metallurgical vehicle is one of core devices in a metallurgical transportation link, has the advantages of environmental protection and efficiency improvement, and can realize the self-propelled and unmanned functions. And the driving speed reducer is a core driving part of the large-axle-weight self-propelled metallurgical vehicle.
The metallurgical vehicle as large metallurgical transport equipment has the main characteristics of large axle weight, large torque and short wheelbase, and the axle weight can reach over 40 tons. The existing axle-holding traveling driving speed reducer technology is mainly applied to occasions with low axle weight, low torque and large axle distance, such as a traction locomotive, a tramcar, an electric locomotive, an electric flat car and the like, the maximum axle weight is only about 30 tons, no design is provided for adapting to the working condition of a self-propelled metallurgical vehicle, and the requirements of axle weight, axle distance and the like cannot be met.
Because the short wheelbase limits the bottom space of the bogie, the installation space of the speed reducer is narrow, the motor and the large gear of the existing axle-holding walking drive speed reducer technology are large, a large amount of space is occupied, and the space requirement of a large-axle-weight self-propelled metallurgical vehicle cannot be met. Meanwhile, the problem that the driving speed reducer is difficult to lubricate and radiate is also caused by compact structure. The prior art adopts a single lubricating mode, the lubricating and heat dissipating capabilities cannot meet the requirements, and the phenomena of poor lubrication and heat dissipation of the high-speed shaft bearing are easy to occur.
The medium for metallurgical vehicle transportation is scrap steel, molten iron and other materials, and especially when the molten iron is transported, stopping and maintaining are forbidden midway before primary transportation is not completed, otherwise major production accidents occur. The single lubrication mode in the prior art has to be immediately stopped and repaired in midway when a fault occurs, and a great production accident is caused.
Because the space of the bogie is limited, the oil seal of the speed reducer cannot be replaced on the premise of not removing the wheel, and the wheel and the axle are scrapped when the wheel is removed. The prior art adopts a single sealing mode, so that the oil leakage risk exists, and if the oil seal is only used for sealing, the oil seal needs to be replaced periodically, so that the maintenance cost and the construction period are wasted.
The large axle weight characteristic of metallurgical vehicles increases the flexural deformation of the drive axle. The prior art does not have a special design for compensating the deflection deformation of the driving axle of the large-axle-weight metallurgical vehicle, so that the problem that the service life of the speed reducer is influenced by the deflection deformation is easy to occur, and meanwhile, the risk of sealing and locking the axle exists, so that the consequence that the vehicle can not be dragged away even if the vehicle stops midway is caused, and a major production accident is caused.
The self-propelled metallurgical vehicle also has an unmanned function, the intelligent level must be satisfied, and the prior art has no design in the aspect of intelligent function and is only a traditional mechanical transmission part.
