Description

Novel piston air compressor

Technical Field

The utility model belongs to the technical field of air compression equipment, a novel piston air compressor machine is related to.

Background

The piston air compressor is an air compressor which changes the internal volume by relying on an air cylinder and a piston which does reciprocating motion in the air cylinder, a motor drives a crankshaft to rotate after being started, the piston does reciprocating motion to work the volume and then can periodically change through the transmission of a connecting rod, the crankshaft rotates for a circle, the piston reciprocates once, the processes of air intake, compression and exhaust are successively realized in the air cylinder, namely, a working cycle is completed, two ends of a piston rod are respectively sleeved on an internal pin shaft of the piston and a crank to realize reciprocating motion, therefore, the two ends of the piston rod are preferably positioned on the same plane, but deviation is inevitable in the actual installation process, because the two ends of the existing piston rod are directly sleeved and installed, deviation is easy to generate in the process of moving, the abrasion between the piston ring and the air cylinder wall is aggravated, and the generated noise is also.

Disclosure of Invention

The utility model aims at providing a to the above-mentioned problem that exists among the prior art, provide a stability good makes the difficult wearing and tearing of piston ring and the novel piston air compressor machine of silence more.

The purpose of the utility model can be realized by the following technical proposal: the utility model provides a novel piston air compressor, includes crankcase and the cylinder that mutually supports the setting, on the bent axle was located to the pot head of air compressor piston rod, the both ends of bent axle passed through bearing and formation support between the crankcase, its characterized in that, piston rod and bent axle between through the axle sleeve connection, be provided with the adjusting shim between both of piston rod and axle sleeve and the lateral wall of bent axle, all seted up the stair structure on two adjusting shims and made its contact surface respectively with the piston rod and the axle sleeve between offset by, the end of bent axle is provided with the adjustable ring, the another side of adjustable ring offsets by with the crankcase inner wall and leans on, and should locate the crankcase and seted up the cavity structure and be used for the installation bearing and be provided with.

The technical effects of the novel piston air compressor are as follows: the piston rod has played the effect of shock attenuation and abrasionproof damage through the bushing, wherein after the piston rod installation, through the thickness that changes its both sides adjusting shim, an axial plane for adjusting piston and piston rod aligns, make the axiality between the two higher, prevent that the piston from accelerating in reciprocating motion because the wearing and tearing that the atress inequality leads to, and leakproofness and life are also better, wherein adjusting shim is through directly leaning on piston rod and axle sleeve, make both synchronous regulations, prevent to produce the clearance skew after mediating, furthermore, change the mounted position of bent axle through the adjustable ring and realize two sections and adjust, it is more convenient to make the debugging, and the tip of bent axle is sealed through integral sealed piece and apron, sealed piece has also played the effect of supporting this department bearing, the design is more reasonable, prevent inside fluid leakage.

In the novel piston air compressor, the crankshaft extends out of the front end of the crankcase and is sealed by installing an oil seal.

In the novel piston air compressor, the crankshaft is positioned outside the crankcase and is fixedly provided with the coupling and the flywheel through the flat key.

In the novel piston air compressor, the shaft sleeve is externally provided with a bushing, and two ends of the bushing are respectively abutted against the piston rod and the adjusting gasket.

Compared with the prior art, this novel piston air compressor machine realizes two sections through setting up adjusting shim and adjustable ring on the bent axle and adjusts, and the axial of the piston rod of being convenient for and piston is with the plane setting, and it is longer to help reducing the difficult wearing and tearing life of skew clearance piston to the silence effect is also better after the unit mount targets in place.
