Novel hydrodynamic lubrication demonstrator

Abstract

The invention discloses a novel hydrodynamic lubrication demonstrator. The novel hydrodynamic lubrication demonstrator comprises a movable ring, a stationary ring, an oil tank filled with silicone oil, a motor and a transmission device, the movable ring and the stationary ring are arranged in the oil tank, the stationary ring is arranged above the movable ring, and the movable ring and the stationary ring are performed with oil seal; the center of the movable ring is connected with a spindle through a flat key, and the spindle is in transmission connection with the motor shaft of the motor through the transmission device; when rotating, an oil film is formed between the movable ring and the stationary ring; wedge-shaped bumps are arranged on the lower surface of the stationary ring at intervals along the circumferential direction, and the lower surface of the stationary ring is matched with the upper surface of the movable ring to form wedge-shaped gaps of the oil film; through holes are formed in the upper surface of the stationary ring and communicated with an oil pressure display pipe and the wedge-shaped gaps, and the upper end of the oil pressure display pipe is communicated with the external environment.

Description

technical field [0001] The invention relates to a novel 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,...
