Abstract

The invention provides a lubricating structure for a low-speed compressor, which includes a compressor body, a base and a shaft seat are fixed on the compressor body, a liquid storage chamber is arranged on the shaft seat, and at least one side of the liquid storage chamber An oil injection hole is provided, and the oil outlet end of the oil injection hole is connected to the gap between the rotating shaft and the shaft seat; a fixed block is fixed on the rotating shaft, and a top block is slidably connected to the shaft seat, and the fixed block The vertical distance between the outer edge and the rotating shaft is greater than the vertical distance between the bottom end of the top block and the rotating shaft; the top of the top block is provided with a seal for opening and closing the oil hole; the present invention uses the fixed block Push the top block up to make the seal close or open the oil injection hole, push the lubricating oil in the liquid storage chamber into the gap between the shaft and the shaft seat through the oil injection hole, and perform intermittent automatic lubrication on the shaft and shaft seat to prevent the rotation of the shaft and the shaft seat. The wear between the shaft seats reduces the wear of the shaft due to frequent shutdowns due to adding lubricating oil.

Description

technical field

[0001] The invention belongs to the field of electromechanical technology, and in particular relates to a lubricating structure for a low-speed compressor. Background technique

[0002] The compressor is used to increase the air pressure entering the engine and supply the compressed air required for the engine to work. It is a component that uses the rotating blades to do work on the air to increase the air pressure. The traditional compressor has a high working speed and the shaft bearing part It is easy to form an oil film and has good lubrication conditions. For low-speed compressors, due to the friction loss between the shaft and the shaft seat during the rotation of the shaft, it is difficult to work the impeller, and it is necessary to stop frequently for oil lubrication between the shaft and the shaft seat. When the compressor restarts after frequent shutdowns, it is easy to cause shaft wear, reduce the service life of the compressor, and affect the no...
