Abstract
The utility model discloses a box body of a gear box. The box body comprises an upper box body and a lower box body fixedly connected with the upper box body, wherein the lower box body is composed of two horizontal side plates, two longitudinal side plates and a bottom plate; a lubricating oil for lubricating a gear is stored on the bottom of the lower box body, and an oil-storing box is arranged in the lower box body; the oil-storing box is enclosed by the two horizontal side plates which can horizontally extend along the lower box body, the two longitudinal side plates which can longitudinally extend along the lower box body and the bottom plate of the lower box body; and the lubricating oil is stored in the oil-storing box and the gear teeth of the gear are immersed in the lubricating oil, and the lubricating oil in the oil-storing box is communicated with the lubricating oil on the bottom of the lower box body. The box body of the gear box provided by the utility model has the advantages that the structure is simple, the bottom of the gear box can keep stable lubricating oil liquid height, a bearing and the gear can be fully lubricated, and the box body is particularly suitable for being used in railway vehicles such as subways.
Description
Technical field
The utility model relates to a kind of casing for transmission part is installed, and particularly relates to a kind of casing of gear-box.
Background technique
Existing gear case body, the gear case body that uses as rail vehicles such as subways, comprise upper box and the lower box that is fixedly connected with this upper box, described lower box is surrounded by two horizontal side plates, two longitudinal side plates and a base plate, bottom at lower box has lubricant oil, in the gear teeth floodlubrication oil of gear.When work, because gear-box adopts splash lubrication, like this when the gear teeth enter at a high speed in bottom half lubricant oil, because velocity attitude and lubricant oil surface have an inclination angle, there is downward component velocity at vertical direction, lubricant oil is forced to a direction motion, and the speed of motion is different and different with the gear rotating speed.When the gear rotating speed is very fast, lubricant oil is poured into surrounding, its horizontal component velocity can have along the thrust on velocity attitude lubricant oil, inhibition because of the last flank of tooth, form again the thrust of dividing to both sides, therefore when the gear teeth enter lubricant oil, can force lubricant oil along gushing on casing surrounding inwall, cause the actual liquid level of lubricant oil when working gear to descend, the actual surface of contact of gear and lubricant oil is reduced, worsen like this working environment of gear, weakened the using effect of lubricant oil, be 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 gear-box bottom of making and keeps stable lubricant oil liquid level height, thereby guarantees that gear can obtain the gear case body of sufficient lubrication.
for solving the problems of the technologies described above, the utility model adopts a kind of like this gear case body, comprise upper box and the lower box that is fixedly connected with this upper box, described lower box is by two horizontal side plates, two longitudinal side plates and a base plate surround, have the lubricant oil of oilgear in the bottom of described lower box, be provided with an oil storage box in described lower box, this oil storage box is by surrounding along two horizontal side plates of described lower box horizontal expansion with along two longitudinal side plates of lower box longitudinal extension and the base plate of lower box, the gear teeth that have lubricant oil and gear in described oil storage box immerse in this lubricant oil, lubricant oil in described oil storage box is connected with the lubricant oil of described lower box bottom.
In the utility model, offer respectively a circular hole bottom two horizontal side plates of described oil storage box, offer respectively an oval hole in two longitudinal side plates bottom of described oil storage box, the lubricant oil bottom described lower box is connected the lubricant oil in described oil storage box by described circular hole and oval hole.
Oil storage box end face of the present utility model flush with described lower box end face or described oil storage box end face lower than 2～5 centimetres of described lower box end faces.
After adopting said structure, an oil storage box is set in lower box due to the utility model, therefore, during gear-box work, when the gear teeth enter the lubricant oil rotary drive, described oil storage box can stop lubricant oil upwards to gush along gear case body surrounding inwall, thereby make the stable lubricant oil liquid level height of gear-box bottom maintenance, guarantee that gear-box can be lubricated fully at operation process middle (center) bearing and gear, lubricant oil can be brought into play effect better when work like this, greatly optimize the working environment of gear, be conducive to improve the Safety performance of locomotive operation.The utility model has solved the problem of the gear-box that in the prior art, lubricant oil causes along gushing on casing surrounding inwall bottom lubricant oil liquid level height decline.
