Abstract

The invention discloses a hydrodynamic pressure lubrication demonstrator. The hydrodynamic pressure lubrication demonstrator comprises a movable ring, a static ring, an oil tank filled with silicone oil, a motor and a transmission device, wherein the movable ring and the static ring are arranged in the oil tank, the static ring is arranged above the movable ring, and the static ring is in oil seal with the static ring; the centre of the dynamic ring is connected with a main shaft by a flat key, and the main shaft is in transmission connection with the motor shaft of the motor by the transmission device; during rotation, an oil film is formed between the movable ring and the static ring; wedge-shaped projections are arranged on the lower surface of the static ring at intervals along a circumferential direction, and the lower surface of the static ring is matched with the upper surface of the movable ring to form the wedge-shaped gaps of the oil film; a through hole is formed in the upper surface of the static ring, the through hole is communicated with an oil pressure display tube and the wedge-shaped gaps, and the upper end of the oil pressure display tube is communicated with an external environment.

Description

technical field [0001] The invention relates to a fluid dynamic pressure lubrication demonstration instrument, which belongs to demonstration teaching aids. Background technique [0002] Construction machinery works under harsh working conditions, bears large loads and frequent impacts, and often breaks down. At this time, we need to reduce the friction between various mechanisms, and the most effective way to reduce the friction and wear between two friction pairs The method is to introduce a lubricant between the friction pairs to form a lubricating film, and the lubricating film bears part or all of the load, so that the friction pairs run smoothly, and the efficiency and life of the equipment are improved. It can be seen that the study of lubrication is of great significance in engineering. Hydrodynamic lubrication is the most effective among all kinds of lubrication. Its friction coefficient and wear are very small, and the oil film has good protection, cleaning, cooli...
