A lubricating device for a reduction gear

Abstract

The invention belongs to the field of lubrication of speed reducing devices, particularly relates to a lubricating device of a speed reducing device, and solves the technical problem that gears and bearings in an existing large speed reduction box are hard to fully lubricate. The lubricating device of the speed reducing device comprises an oil pump which is mounted in a reduction gearbox body of a vehicle, and a lever; the lever is rotatably mounted on the reduction gearbox body, one end of the lever is connected with a roller, and a cam is fixedly arranged on an axle of the vehicle; the roller is tightly contacted with the cam; the other end of the lever is contacted with a plunger of the oil pump; an oil inlet of the oil pump is hermetically connected with an oil suction pipe, the oil outlet of the oil pump is hermetically connected with an oil drain pipe, and the other end of the oil drain pipe guides lubricating oil to a to-be-lubricated part. According to the lubricating device provided by the invention, power of the axle of the vehicle is effectively utilized and no extra power is required, so that the lubricating device is very practical and is just mounted in the existing device to realize the work of conveying the lubricating oil to the to-be-lubricated part. The whole device is simple in structure, practical and convenient.

Description

Technical field [0001] The invention belongs to the field of lubrication of a deceleration device, in particular to a lubrication device of a deceleration device. Background technique [0002] According to the purpose of some rail cars, the running speed is relatively slow. The reduction gear needs to adopt two-stage reduction. In order to ensure sufficient lubrication of the gears and bearings in the reduction gear, the secondary gears are immersed in lubricating oil. When the rail car is running, With the rotation of the secondary gear, the lubricating oil is thrown up, flows down the box of the reduction box, and flows to the bearing location, so that the bearing can be lubricated to a certain extent to ensure its normal operation. When the rail car is running fast, the lubricating oil There are also many splashes, and gears and bearings can be fully lubricated. However, when the reduction box is large, the installation position of the first-stage reduction gear is higher, and...

Problems solved by technology

[0002] According to the use of some rail cars, their running speed is relatively slow, and the reduction device needs to adopt two-stage reduction. In order to ensure the sufficient lubrication of the gears and bearings in the reduction device, the secondary gears are soaked in lubricating oil. When the rail car is running, With the rotation of the secondary gear, the lubricating oil is thrown up, flows down the box of the reduction box, and flows to the position of the bearing, so that the bearing can be lubricated to a certain extent to ensure its normal operation. When the rail car runs fast, the lubricating oil There is also a lot of splashing, and the gears and bearings can be fully lubricated. However, when the reduction box is large and the installation position of the first-stage reduction gear is higher, the lubricating oil thrown up by the second-stage gear alone is not enough to make the first-stage reduction. If the gears and bearings are fully lubricated, it is necessary to have a lubricating device for supplementary lubrication, so that the bearings and gears of the reduction gear can be fully lubricated, so as to ensure the normal operation of the entire reduction gear
