Example Embodiment

[0009] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. This embodiment is implemented on the premise of the technical solution of the present invention. Detailed implementation modes and specific operation procedures are given, but the protection scope of the present invention is not limited to the following Mentioned examples.

[0010] Such as figure 1 As shown, the vertical reducer with vertical shaft bearing lubricating oil circulation device according to the present invention includes a vertical reducer body 1. The gear box 2 of the vertical reducer body 1 is located on the bottom wall of the gear box 2 and the power output shaft 3. An end cover 7 is provided at the position of the lower bearing chamber 4, and an oil guide tube 5 is provided at the bottom of the end cover 7. One nozzle of the oil guide tube 5 communicates with the lower bearing chamber 4 and the other nozzle is connected to the oil sump 6...

Abstract

The invention discloses a vertical reducer with a vertical shaft bearing lubricating oil circulation device, comprising a vertical reducer body, the bottom wall of the gearbox of the vertical reducer body, and a bearing chamber located under the power output shaft of the gearbox An oil guide pipe is arranged at the position, one nozzle of the oil guide pipe communicates with the lower bearing chamber and the other nozzle communicates with the oil pool in the gearbox; the lower end of the gearbox power output shaft extends to the bearing In the chamber, an impeller is fixed on the power output shaft of the gearbox extending into the bearing chamber. The invention has the advantage of realizing the forced circulation of the lubricating oil in the lower bearing chamber of the power output shaft, preventing the occurrence of super high temperature rise of the bearing caused by the impurity precipitation due to the failure of the lubricating oil at the bearing position of the lower bearing chamber.

Description

technical field [0001] The invention relates to a vertical reducer, in particular to a vertical reducer with a vertical shaft bearing lubricating oil circulation device. Background technique [0002] Vertical reducer is widely used in large powder processing equipment such as vertical mill, and its vertical shaft (power output shaft) is used as the main power to drive the mill to work. The bottom bearing of the vertical shaft of the vertical reducer is installed in the bearing sleeve, and the bearing sleeve is installed or connected to the bottom plate of the reducer, and is directly immersed in the oil pool of the gearbox. When the vertical reducer is working, the lubricating oil entering the bearing sleeve is difficult to exchange and circulate with the lubricating oil in the gearbox oil pool due to the cup-shaped structure of the bearing sleeve, resulting in rapid oil deterioration. Impurities are easy to deposit in the bearing sleeve, causing serious heating of the bear...
