Traction motor bearing lubricating device

The invention discloses an oil lubricating device for a traction motor bearing. The technical problems that in the prior art, lubricating oil is prone to splashing and loss in a gearbox and pollutes the surrounding environment are solved. The device comprises an oil receiving box which is arranged on a bearing cover and used for collecting lubricating oil splashed out along with a gear, an oil inlet hole communicated with a bearing and the oil receiving box is formed in the bearing cover, and the lubricating oil in the oil receiving box is injected into the bearing through the oil inlet hole. The stainless steel pipe is simple in structure, scientific and reasonable in design, convenient to use and manufacture and low in cost, and is formed by welding austenitic stainless steel plates; the lubricating oil can be collected, oil sludge, scrap iron and other impurities in the lubricating oil can be effectively filtered, the bearing lubricating effect is finally achieved, reliable operation of the motor bearing c
