The invention discloses a gear box which comprises a box body, a small gear and a large gear which are meshed with each other are arranged in the box body, and the lower portion of the large gear is immersed in lubricating oil. The box cover is hermetically mounted at the top of the box body; wherein an oil collecting groove is formed at the combined part of the box body and the box cover, and an oil way is formed between the oil collecting groove and a small bearing of the small gear, so that lubricating oil which is stirred by the large gear and splashed to the oil collecting groove flows to the small bearing along the oil way to lubricate the small bearing. The problem that in the prior art, when a gear box operates under the low-speed and low-temperature working conditions, lubrication of a gear box bearing is poor is solved.

    本发明公开了一种齿轮箱,包括:箱体,箱体内部设置有彼此啮合的小齿轮以及大齿轮,大齿轮的下部浸没在润滑油中;以及箱盖,密封安装在箱体的顶部;其中,在箱体与箱盖结合的部位形成集油槽,集油槽与小齿轮的小轴承之间形成油路,使得经大齿轮搅动飞溅到集油槽的润滑油沿油路流至小轴承,以润滑小轴承。克服了现有技术中齿轮箱在低速、低温工况下运行时,齿轮箱轴承润滑不良的问题。
