Air film forming device and reciprocating motor

Abstract

The invention is applicable to the technical field of air film lubrication devices for machines, and provides an air film forming device, which is characterized in that it includes: a cavity, which is a cylindrical structure, and two ends of the cavity are provided with installation holes; The cover includes a front sealing cover and a rear sealing cover. The front sealing cover and the rear sealing cover are respectively connected to both sides of the cavity through installation holes. The rear sealing cover is provided with an air filling port and a limiting A pressure valve; a piston, which is arranged inside the cavity, and the piston is provided with an air channel, the air channel includes an air inlet, an air storage channel and an air outlet, and the air inlet is provided with a single The air outlet is arranged on the side of the piston, and both the air inlet and the air outlet are in communication with the air storage channel. In this way, the traditional oil film lubrication needs to replace the lubricating medium and is greatly affected by the ambient temperature. Through the air film forming device, the air film is formed between the parts to reduce the friction loss of the parts and simplify the structure of the machine.

Description

technical field [0001] The invention relates to the technical field of air film lubrication devices for machines, in particular to an air film forming device and a reciprocating motor. Background technique [0002] In traditional moving parts, especially those involving reciprocating and rotating motions, the lubrication is achieved by adding liquids such as lubricating oil or solid lubricating media such as grease, which will be lubricated during operation. An oil film is formed between the parts that move with each other to ensure that there will be no dry friction between the parts, but with this lubrication method, an additional lubricating mechanism needs to be added to ensure the formation of the oil film, which increases the manufacturing cost of the machine; Moreover, it is necessary to replace the lubricating medium regularly to ensure the cleanliness of the lubricating medium; it is difficult to form an oil film when the ambient temperature is low, which leads to s...
