Problems solved by technology

[0002] At present, most of the propulsion motors and marine propulsion motors with high environmental protection requirements use forced lubrication sliding bearings. Due to the special application occasions, it is required to ensure the uninterrupted supply of lubricating oil, which brings a lot of inconvenience to the overall system design. For example It is required that the overall must be equipped with low-pressure oil supply system and other issues
The lubrication of motor bearings in the prior art cannot guarantee a sufficient supply of lubricating oil at each speed, and the oil scraping effect is better when the speed is lower than the critical speed, but when the speed is higher than the critical speed, the lubricating oil splashes around, and the oil scraping effect is poor , the effect of receiving oil is not good, resulting in insufficient supply of lubricating oil, which greatly reduces the reliability of self-lubricating sliding bearings

Abstract

The invention relates to a contact mechanical oil carrying device for a sliding bearing. The mechanical oil carrying device is suitable for propulsion motors and wind power generation equipment, particularly ship propulsion motors. The mechanical oil carrying device comprises an oil carrying disc, an oil scraping device and an oil receiving device; the oil carrying disc is a whole annular circular disc which is formed by combining two semi-rings; one end face of the annular circular disc is provided with an annular oil carrying groove; the oil carrying disc is fixedly connected with a rotation shaft; one end of a support of the oil scraping device is provided with an oil scraping plate, and the support is fixedly connected with the upper part of the oil receiving device; and the oil receiving device has a box shape, and the bottom of the oil receiving device is fixedly connected with the sliding bearing, namely the upper part of a bearing bush, and is also provided with an oil outlet which is communicated with an oil injection hole of the sliding bearing. The mechanical oil carrying device has an extremely excellent oil scraping effect, realizes the reliable lubrication of the bearing in high and low speed and an inclination state, has the advantages of compact and simple structure, high reliability, and the like, is convenient to maintain, radically solves the oil supply problem of a self-lubricating sliding bearing, and provides technical support for engineering application of a large-diameter self-lubricating sliding bearing.
