The invention discloses a railway vehicle gear box lubricating structure and a railway vehicle gear transmission device. The lubricating structure comprises an oil storage tank body fixed in a small gear box and a lubricating oil pump fixed in a large gear box, and the lubricating oil pump is in transmission connection with a large gear through a transmission mechanism; the oil storage tank body is arranged above a small gear shaft, an oil hole is formed in the oil storage tank body, and the oil hole is used for communicating the oil storage tank body with a lubricating oil channel on a small gear bearing; the bottom wall of the gear box is sunken downwards to form a second oil storage tank, an oil baffle plate is arranged in the second oil storage tank, and the oil baffle plate divides the second oil storage tank into a first area located below the large gear and a second area located below the small gear box; and the lower end of the large gear extends into the first area, an oil suction pipe of the lubricating oil pump extends into the second area, and an oil discharge pipe of the lubricating oil pump extends into the first oil storage tank. According to the lubricating structure, lubricating oil channels do not need to be formed in all parts, complex lubricating pipelines do not need to be arranged, and thus the economical efficiency and reliability are greatly improved.

    本发明公开了一种轨道车辆齿轮箱润滑结构及轨道车辆齿轮传动装置,润滑结构包括固定于小齿轮箱内的储油槽体,和固定于大齿轮箱内的润滑油泵,润滑油泵通过传动机构与大齿轮传动相连;储油槽体设于小齿轮轴的上方,储油槽体上开设有油孔,油孔用于连通储油槽体与小齿轮轴承上的润滑油道;齿轮箱的底壁向下凹陷形成第二储油槽,第二储油槽内设有挡油板,挡油板将第二储油槽分隔为位于大齿轮下方的第一区,和位于小齿轮箱下方的第二区;大齿轮的下端伸入第一区内,润滑油泵的吸油管伸入第二区内,润滑油泵的排油管伸入第一储油槽中。该润滑结构无需在各部件上开设润滑油道,也无需设置复杂的润滑管道,经济性和可靠性大大提高。
