Lubricating oil self-circulation device for reduction gearbox of wire drawing machine

Abstract

The invention discloses a lubricating oil self-circulation device for a reduction gearbox of a wire drawing machine. The lubricating oil self-circulation device comprises an auxiliary box, a connecting pipe, an injection ball and an auxiliary pipe, the auxiliary box is filled with lubricating oil, and the upper surface of the lubricating oil in the auxiliary box is slightly higher than that of the lubricating oil in the reduction gearbox. The two ends of the connecting pipe horizontally communicate with the lower portion of the reduction gearbox and the lower portion of the auxiliary box respectively, and a one-way valve is arranged on the connecting pipe so that lubricating oil can only flow into the auxiliary box from the reduction gearbox. The injection ball is of a hollow structure, the lower portion of the injection ball communicate with a plurality of injection pipes in a scattering mode, and the injection ball is fixed to the center of the top of the reduction gearbox. The two ends of the auxiliary pipe communicate with the lubricating oil in the auxiliary box and the injection ball correspondingly, and a driving mechanism is further arranged in the auxiliary box so as to drive the lubricating oil in the auxiliary box to flow into the injection ball through the auxiliary pipe. According to the device, lubricating oil of the reduction gearbox can be cyclically replaced, meanwhile, all-directional lubrication in the reduction gearbox is achieved, and the working performance of the reduction gearbox is guaranteed.

Description

technical field [0001] The invention relates to the technical field of metal product processing equipment. More specifically, the invention relates to a lubricating oil self-circulation device for a reduction box of a wire drawing machine. Background technique [0002] The conventional method of lubricating the reduction box of the wire drawing machine is to pour lubricating oil directly into the reduction box, so that the lubricating oil is located in the casing of the reduction box, and the lower part of the worm wheel of the reduction box is immersed in the oil pool formed by the lubricating oil, and the lubricating oil can be released when rotating Splash to various parts of the gearbox to achieve lubrication of the gearbox. This conventional lubrication method will have the following problems: 1) The lower part of the gear or worm wheel is immersed in lubricating oil, which requires a lot of lubricating oil. When the amount of oil is too much, stirring will occur with ...

Problems solved by technology

This conventional lubrication method will have the following problems: 1) The lower part of the gear or worm wheel is immersed in lubricating oil, which requires a lot of lubricating oil. When the amount of oil is too much, stirring will occur with the rotation of the worm wheel, and the lubricating oil will heat up, thus affecting the reduction box. 2) With the work of the gearbox, there will be some iron chips, dust and sand and other impurities in the lubricating oil, and the gears or worm gears in the lubricating oil will be corroded, reducing the effect of the lubricating oil, and the lubricating oil needs to be replaced frequently , or replace the worm gear, the cost is high; 3) With the work of the gearbox, the lubricating oil heats up or is mixed with impurities, which affects the service life of the gearbox, and it is necessary to replace the lubricating oil or cool down in time; 4) The gearbox If the oil level of the lubricating oil in the gearbox is a little lower, the lubricating oil will not be able to achieve good lubrication, which will cause the parts in the reduction box to be worn or damaged due to poor lubrication
