Abstract

The invention discloses a direct connection air compressor set. The direct connection air compressor set comprises a diesel engine and an air compressor. The diesel engine comprises a diesel engine crankshaft and a diesel engine crankshaft case. The air compressor comprises an air cylinder, an air compressor crankshaft case and an air compressor crankshaft. The diesel engine crankshaft is connected with a diesel engine flywheel, the diesel engine flywheel is arranged in a diesel engine flywheel shell, and the diesel engine flywheel shell is fixedly arranged on the diesel engine crankshaft case. The air compressor crankshaft is connected with an air compressor flywheel, the air compressor flywheel is arranged in an air compressor flywheel shell, and the air compressor flywheel shell is fixedly arranged on the air compressor crankshaft case. The air compressor flywheel shell is in direct rigid connection with the diesel engine flywheel shell, and the air compressor flywheel is in transmission connection with the diesel engine flywheel through a coupler. According to the direct connection air compressor set, direct connection between the air compressor and the diesel engine is achieved, and the direct connection air compressor set is small in occupied space, small in vibration as a whole, high in reliability and not prone to damage.

Description

technical field [0001] The invention relates to the technical field of air compressors, in particular to a direct-coupled air compressor unit. Background technique [0002] At present, the air compressor used on the powder transport vehicle is generally driven by a diesel engine. The air compressor and the diesel engine form a diesel-powered air compressor unit. The diesel engine and the air compressor are installed independently, and the power input end of the air compressor is provided with a space Compressor pulley, the power output end of the diesel engine is connected to the diesel engine pulley through a clutch, and a V-belt is connected between the air compressor pulley and the diesel engine pulley, and the power output end of the diesel engine and the crankshaft power input end of the air compressor are connected to transmit power through a V-belt . This installation and connection method of the diesel-powered air compressor unit formed after the existing air compre...

AI Technical Summary

Problems solved by technology

With the existing installation and connection method of the diesel engine, the air compressor is under alternating load during operation, which will generate alternating force and cause large vibrations. If the air compressor and the diesel engine are connected through a V-belt, through Force transmission to connect, so that the whole unit generates horizontal vibration, and this horizontal vibration is very harmful, resulting in high damage rate and low reliability of the whole vehicle and parts

[0004] 2. Make the structure of the unit complex

In the existing installation and connection method of the diesel engine, the power output device of the diesel engine needs to be equipped with a V-belt pulley, and the power input device of the air compressor needs to be equipped with a larger V-belt pulley. The belt connection will generate a large radial force, and the requirements for the radial bearing capacity of the power output device of the diesel engine and the air compressor will be correspondingly increased, which will make the structure of the unit more complicated.

[0005] 3. Make the unit larger

In the existing installation and connection method of the diesel engine, the diesel engine and the air compressor are installed independently, which takes up a large space. In addition, the transmission ratio of the air compressor and the diesel engine is greater than 2, and the diameter of the pulley of the air compressor is relatively large, making the diesel engine The distance between the air compressor and the air compressor has to be increased, making the volume of the entire diesel air compressor unit larger

[0006] 4. The existing installation and connection method of the diesel engine, the power transmission efficiency is low through the connection of the V-belt, the fuel consumption is high, and the economy is poor, and the V-belt is easy to be damaged and needs to be replaced frequently, which is laborious and laborious

[0007] 5. The speed of the existing air compressor is relatively low, generally between 950 and 1000r / min, and the air compressor with the same volume has a relatively low displacement
