Description
Technical field
The embodiment of the present invention relates to locomotive manufacturing technical field, particularly relates to a kind of driving structure for macro-axis heavy-duty machine car pinion bearing grease lubrication.
Background technique
The main trend of macro-axis heavy-duty machine Che Shi world railway freight development is also the developing direction of current railway freight.For improving the economic benefits of transportation efficiency, axle has progressively heavily been brought up to 30 tons by most of European countries, and GE company of the U.S. and EMD company also produce the heavy internal combustion locomotive of 32 tons of a large amount of axles for this reason.China is also just at the middle and south, newly-built Shanxi rail channel and prepare newly-built illiteracy to Central China heavy haul railway passage.Because of the increase of Locomotive Axle Load, tractive force, electric motor starting and rated torque, for bogie drive system, freely supported structure is selected to replace traditional motor driving gear cantilever structure, pinion bearing (traction electric machine output terminal bearing) moves in gear-box by this structure, adopts gear oil splash lubrication.This driving structure, being subject to easily to scurry out to the tremendous influence of bearing life, lubricant oil after gear oil pollutes causes traction electric machine scaling loss or the risk of catching fire and the restriction because of design space, cause the situations such as bearing lubricating oil circuit project organization complexity, have a strong impact on the driving safety of locomotive and the increase of processing cost.
Summary of the invention
The invention provides a kind of driving structure for macro-axis heavy-duty machine car pinion bearing grease lubrication, in order to solve defect of the prior art, guarantee the reliability of driving device for locomotives, so the security of operation of whole locomotive.
The embodiment of the present invention provides a kind of driving structure for macro-axis heavy-duty machine car pinion bearing grease lubrication, and this driving structure being used for macro-axis heavy-duty machine car pinion bearing grease lubrication comprises:
Gear-box, the tank wall of described gear-box has grease injection hole;
Pinion bearing, is arranged on the tank wall of described gear-box, is provided with between movable sealing structure and depot fat in the both sides of described pinion bearing, injects lubricating grease by described grease injection hole between described depot fat, to mend lubricating grease to described pinion bearing.
Driving structure for macro-axis heavy-duty machine car pinion bearing grease lubrication provided by the invention; by cancelling complicated pinion bearing lubricating oil path in gear-box; arrange in bearing both sides between good movable sealing structure and depot fat; and grease injection hole is had on gear-box tank wall; to mend lubricating grease in locomotive operation process at regular time and quantity to bearing; the reliability of driving device for locomotives can be guaranteed, so the security of operation of whole locomotive.
Accompanying drawing explanation
The plan view of the driving structure for macro-axis heavy-duty machine car pinion bearing grease lubrication that Fig. 1 provides for one embodiment of the invention.
Embodiment
For making the object of the embodiment of the present invention, technological scheme and advantage clearly, below in conjunction with the accompanying drawing in the embodiment of the present invention, technological scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
