Abstract

The invention provides a reduction gearbox lubricating system. The reduction gearbox lubricating system comprises a gearbox shell, a sun gear, a planet carrier, a gear ring, an annular oil baffle plate and a forced lubricating unit. The housing is provided with a first bearing and a second bearing. The central gear is rotatably arranged on the box shell. The planet carrier is simultaneously connected with the first bearing and the second bearing; the planet carrier is provided with a planet wheel assembly with a first oil conveying hole. The gear ring is connected with the box shell, and the planetary gear is meshed with the gear ring. The annular oil baffle plate is connected with the planet carrier, and the forced lubrication unit is configured to force lubricating oil to enter the first bearing. And at least part of the first bearing is located in an area defined by the annular oil baffle plate, so that lubricating oil leaving from the first bearing falls into the annular oil baffle plate, the annular oil baffle plate is used for pressing the lubricating oil into the first oil conveying hole in the rotating process, and the lubricating oil in the first oil conveying hole can sequentially enter the planet wheel assembly and the second bearing. The lubricating effect is good.

Description

technical field [0001] The invention relates to the technical field of lubrication, in particular to a reduction box lubrication system. Background technique [0002] The planetary gearboxes used in vehicles are mostly splash lubrication. With the development of new energy vehicles, the motor speed is getting higher and higher. If there is a lot of oil in the gearbox, the oil churning loss of the gearbox will be very obvious, which will seriously affect the transmission efficiency. If there is less oil in the gearbox, at high speed, the planetary gear will stir up most of the lubricating oil, filling the entire gearbox, and the lubricating oil attached to the gear will be removed from the tooth surface under the action of high-speed centrifugal force. It is difficult to provide enough lubricating oil for the gear meshing position. [0003] The inventor's research found that the existing reducer has the following shortcomings: [0004] Poor lubrication. SUMMARY OF THE INV...
