Embodiment

[0017] The passive non-pre-lubricated gear transmission is the key equipment supporting the nuclear secondary charging pump. There are only a few gearbox transmission manufacturers in the world who can manufacture it. The passive non-pre-lubricated gear transmission device of the present invention is matched with the nuclear secondary charging pump, from emergency start to normal operation of the gear box, during this period of time it is entirely dependent on natural phenomena and passive lubrication, and no one is involved in it, so artificial Minimizing the risk of operating errors, avoiding human error, and ensuring the safety of effective nuclear measures are the design goals. Since the gear transmission is used in nuclear secondary equipment, when the nuclear secondary charging pump in the specially designed safety facility receives the start signal, it needs to be put into operation immediately. There is no pre-lubrication process for gears and sliding bearings, which i...

Abstract

The invention relates to a non-motile non-prelubricating high-speed gear device aiming to the condition that a non-motile non-prelubricating device technology is blockaded by foreign enterprises, and the assorted application of national nuclear secondary charging pumps is directly influenced. The non-motile non-prelubricating high-speed gear device is designed for realizing that a nuclear secondary charging pump of a nuclear power system can immediately start in danger without preliminarily providing gear and sliding bearing lubricating oil processes and solving the technical problems of misoperation caused by manual operation, and the like. The non-motile non-prelubricating high-speed gear device mainly comprises a gearbox and a lubricating oil station, wherein the gearbox is provided with two oil storage cavities, i.e. an oil storage cavity tank for gear bearing lubrication and an oil delivery cavity for gear lubrication, the lubricating oil station is communicated with the oil storage cavity tank for gear bearing lubrication through an oil intake pipeline, and the oil storage cavity tank for gear bearing lubrication is communicated with the oil delivery cavity for gear lubrication and forms a loop with an oil tank of the lubricating oil station as the base of the gearbox through an oil return pipeline on an oil return tank. The invention has the advantages that non-motile non-prelubricating gears and bearings are realized in emergence by utilizing the physical phenomena of the earth gravity and the substance gravity, misoperation caused by manual operation is lessened and avoided, and the safe, reliable and stable operation of the gears and the bearings are guaranteed.

Description

Technical field: [0001] The invention relates to a gear transmission device, in particular to a passive high-speed gear device without pre-lubrication. It belongs to the gear transmission device used in the secondary charging pump of the nuclear power system. Background technique: [0002] As a safe, clean and efficient energy source, nuclear power has become the second largest energy source in the world after thermal power. For this reason, the country plans to build another 18 million kilowatts of nuclear power units on the basis of reaching 40 million kilowatts of nuclear power installed capacity in 2020. There are various levels and types of pumps in operation in each system of a nuclear power plant. The high-speed gear transmission matched with the charging pump is one of the indispensable gear transmissions in the nuclear power industry. This product is different from gear drives in other industrial fields. Since the gear device is used in nuclear secondary equipme...
