Abstract
The utility mode discloses an oil-storing structure of a gear box. The gear box is internally provided with a small gear and a large gear matched with the small gear, and the small gear is driven by an input shaft to rotate; the input shaft is rotatablely arranged on a box body of the gear box through a bearing; lubricating oil is stored on the bottom of a box body of the gear box, and the gear teeth of the large gear are immersed in the lubricating oil; a first oil collecting groove and a second oil collecting groove are respectively arranged on the inner wall of the box body of the gear box and are respectively positioned above and below the a rotation shaft line of the input shaft; and the first oil collecting groove and the second oil collecting groove are respectively provided with a first through hole and a second through hole, and the first through hole and the second through hole are respectively communicated with the bearing on the input shaft. The oil-storing structure provided by the utility model has the advantages that the structure is simple, whatever the gear box rotates in forward direction or in reverse direction, the bearings on the two sides of the input shaft are fully lubricated, the work environment of the bearing is optimized, and the oil-storing structure is particularly suitable for being used in railway vehicles such as subways.
Description
Technical field
The utility model relates to a kind of gear-box, particularly relates to the gear-box oil-bearing structure of the rail vehicles such as subway.
Background technique
The gear-box of existing use in the rail vehicles such as subway, comprise small gear and with the gearwheel of this small gear engagement fit, described small gear is driven by input shaft and rotates, described input shaft is arranged on the casing of gear-box rotationally by bearing, bottom half at described gear-box has lubricant oil, and the gear teeth of described gearwheel immerse in described lubricant oil.The gear-box of this structure because the bearing that meshes input shaft both sides in operation process at gear can not get lubricating fully, thereby has worsened the working environment of bearing, is unfavorable for the safe operation of locomotive.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of bearing of input shaft both sides that can make and obtains sufficient lubrication in the gear-box operation process, thereby optimizes the gear-box oil-bearing structure of bearing working environment.
for solving the problems of the technologies described above, the utility model adopts a kind of like this gear-box oil-bearing structure, be provided with in described gear-box small gear and with the gearwheel of this small gear engagement fit, described small gear is driven by input shaft and rotates, described input shaft is arranged on the casing of gear-box rotationally by bearing, bottom half at described gear-box has lubricant oil, the gear teeth of described gearwheel immerse in described lubricant oil, on the cabinet wall of described gear-box and the above and below that is positioned at described input shaft rotational axis be respectively equipped with the first oil trap and the second oil trap, at described the first oil trap, offer respectively the first through hole on the second oil trap, the second through hole, described the first through hole, the second through hole is connected with bearing on described input shaft respectively.
As a kind of preferred implementation of the present utility model, described the first oil trap is arranged on gear case body inwall directly over described input shaft rotational axis, and described the second oil trap is arranged on the gear case body inwall of contiguous described input shaft rotational axis horizontal position below.
After adopting said structure, the first oil trap and the second oil trap are set on the cabinet wall of gear-box due to the utility model, described the first oil trap and the second oil trap lay respectively at the above and below of input shaft rotational axis, offer respectively the first through hole, the second through hole on the first oil trap, the second oil trap, described the first through hole, the second through hole are connected with bearing on input shaft respectively.Like this in the gear-box operation process, when gearwheel turns clockwise, when being the running of gear-box forward, the lubricant oil that gearwheel will stick on its flank of tooth is thrown to the first oil trap, and the lubricant oil that then is gathered in the first oil trap carries out sufficient lubrication to bearing in the first through hole flows into the bearing of input shaft both sides; When gearwheel is rotated counterclockwise, when being the gear-box antiport, the lubricant oil that small gear will stick on its flank of tooth is thrown to the second oil trap, then the lubricant oil that is gathered in the second oil trap carries out sufficient lubrication to bearing in the second through hole flows into the bearing of input shaft both sides, therefore, no matter gear-box is forward running or antiport, the bearing of input shaft both sides can be lubricated fully, lubricant oil has been brought into play effect better when work, greatly optimize the working environment of bearing, be conducive to improve the Safety performance of locomotive operation.
