Connecting rod and air compressor with the connecting rod

Abstract

The invention discloses a connecting rod and an air compressor with the same. The main point of the technical scheme lies in that the connecting rod includes a big head end, a small head end and a connecting part, the big head end and the small head end are connected by the connecting part, the big head end is provided with a regulating mechanism for regulating the axial thickness and a limiting mechanism for limiting axial movement of the regulating mechanism, and by disposing the regulating mechanism for regulating the axial thickness at the big head end of the connecting rod, when a spacing exists between the connecting rod and a crank arm, the axial thickness can be adjusted by the regulating mechanism, so that the connecting rod can abut against the crank arm. When the air compressor works, the stability is good, the connecting rod is unlikely to shake, so that the noise is low. Also, as the axial thickness is adjustable, the connecting rod is applicable to multiple occasions and crankshafts of various specifications, and has significant practicability. At the same time, due to small shake, the connecting rod is unlikely to break down, has no need for frequent replacement, and has long service life.

Description

technical field [0001] The invention relates to the field of air compression, more specifically, it relates to a connecting rod and an air compressor with the connecting rod. Background technique [0002] As an air source that can provide clean air, air compressors have a very wide market in medical, food, chemical and other industries that have high requirements for air quality. There are many compression methods for air compressors, among which there is a piston air The compressor realizes air compression by driving the connecting rod piston to reciprocate in the cylinder through the rotation of the crankshaft. In the piston air compressor, the connecting rod is one of its important components. [0003] The crankshaft mainly includes a main shaft, a crank pin and a crank arm, wherein the main shaft and the crank pin are arranged on different axes, and the main shaft and the crank arm are connected by the crank pin, and the big end of the connecting rod is sleeved on the cr...

Problems solved by technology

[0003] The crankshaft mainly includes a main shaft, a crank pin and a crank arm, wherein the main shaft and the crank pin are arranged on different axes, and the main shaft and the crank arm are connected by the crank pin, and the big end of the connecting rod is sleeved on the crank pin. Corresponds to a crankshaft of one specification, but in the usual installation process, due to the mismatch of specifications or the deviation of precision in the production and processing process, it is often encountered that the axial thickness of the large head of the connecting rod is smaller than the distance between the two crank arms , the end face of the big head does not interfere with the crank arm, which is prone to shaking when the air compressor is working, poor stability, and increased noise, and even causes the connecting rod to be easily damaged, which needs to be replaced frequently, which is not practical

[0004] At present, the air compressors on the market generally have a displacement of about 250L / min, but in some specific occasions in life, a large amount of compressed air is needed, and if an ordinary air compressor on the market is used, it can also provide Compressed air, but the exhaust volume is small, the efficiency is low, and it needs to consume more energy to produce the same air volume, which is not practical and needs further improvement
