Abstract
The utility model relates to an oilless pendulum-type air compressor, which improves the service life of parts due to the change of structure and comprises a body shell, a crankshaft, a connecting rod, a rotor, a steam cylinder, a valve seat, a sensor seat and a belt pulley; wherein, the crankshaft is arranged on the body shell; the connecting rod is arranged on the crankshaft; the other end of the connecting rod is arranged at one end of a shaft of the rotor by a connecting part; the rotor is arranged in the steam cylinder; one end of the crankshaft is provided with the belt pulley and the other end thereof is provided with the sensor seat; and the steam cylinder is fixed with the valve seat. The utility model is characterized in that the connecting rod is arranged on the crankshaft by a pin shaft; a rolling bearing is arranged between the connecting rod and the pin shaft; a plurality of concave parts are respectively distributed on the connected end surface of the connecting part between the steam cylinder and the body shell; and an air inlet is respectively arranged at the steam cylinder and the body shell. The front end of the air inlet is provided with an air filter. As an oil supply device is removed, the utility model expands use range, prolongs working time, increases torque, reduces shaft power, improves lubrication effect and guarantees the safety of lubrication.
Description
Technical field:
The utility model relates to the field of air compressor, a kind of specifically oil-free pendulum type air compressor
Background technique:
The transmission device of the oil-free pendulum type air compressor that present cement bulk car is used all is to adopt the connecting rod bearing shell formula, mainly is made up of parts such as connecting rod, bent axle, connecting rod shank bearing housing, bearing shell, oil pump, gear, umbrella gear.Under prime motive power drives such as motor car engine or motor, make malaria seat mansion of a prince swing in cylinder by v belt drive bent axle, connecting rod, rocking arm, and then generation operation power, the bent axle of this transmission device lubricates with bearing shell, bearing shell needs to come oiling with oil pump, and oil pump need be used gear, companion's umbrella gear to connect transmission again and could work.
The defective that this device exists is: 1. because the bearing shell rubbing surface is beaten operating temperature original text, easily " tile kilning ", thereby stream time can only be about 60 minutes, and noise is bigger; Since oil pump can only when just changeing, give the bearing shell oiling, so this transmission device can only just change, can not reverse, thereby make installation, the use all be restricted.
In China Patent No. is that " 200320112831.5 " title " oil-free pendulum type air compressor transmission device " provides a kind of and replaces bearing shell with bearing, need not the oil-free pendulum type air compressor transmission device of parts such as oil pump, gear, umbrella gear.
Summary of the invention:
The purpose of this utility model is in order to solve above-mentioned existing problem, a kind of oil-free pendulum type air compressor is provided, it comprises body shell, bent axle, connecting rod, rotor, cylinder, valve seat, sensor holder, belt pulley, wherein bent axle 2 is contained on the body shell, connecting rod 3 is installed on the bent axle 2, the other end of connecting rod 3 is contained in an end of the axle of rotor 4 by link 10, rotor 4 is contained in the cylinder 5, and bent axle 2 one ends are equipped with belt pulley 9, and the other end is equipped with sensor holder 7; Be fixed with valve seat 6 on the cylinder 5, it is characterized in that: connecting rod 3 is contained on the bent axle 2 by bearing pin 11, between connecting rod 3 and bearing pin 11, rolling bearing 12 is housed, on the connection end face of link 10 between cylinder 5 and the body shell 1, be evenly distributed with several recesses, on cylinder 5 and body shell 1, leave suction port 13 and 14 respectively.Front end at suction port is equipped with air-strainer 8.
The utility model has the advantages that: crankshaft crank changes rolling bearing into by sliding bearing, has removed oil supplying device, increases using scope, has prolonged the operating time, adds high pulling torque, reduces air horsepower, improves lubrication effect, guarantees lubricated safety.Be evenly distributed with several recesses on the connection end face of link, reduce the link heat transfer area, make the driving mechanism lubricating oil temperature hang down 20 ° of C, reduce delivery temperature, improve air displacement, lengthen working hours.Change airintake wind-tunnel into two-chamber by single chamber, reduce impulse action, secondary reduces delivery temperature, improves component working life greatly.Owing to do not need oil supplying device, the fuel feeding that splashes is not strict with lubricant oil, compressor is not turned to require, and decides with need of work, and not strict to requiring season, rotation is steadily light and handy, and noise is low, also can bear moment of torsion and hit.

Embodiment:
The utility model oil-free pendulum type air compressor transmission device includes connecting rod, bent axle, body shell, rotor, cylinder, valve seat, sensor holder, belt pulley, wherein bent axle 2 is contained on the body shell, connecting rod 3 is installed on the bent axle 2, the other end of connecting rod 3 is contained in an end of the axle of rotor 4 by link 10, rotor 4 is contained in the cylinder 5, bent axle 2 one ends are equipped with belt pulley 9, and the other end is equipped with sensor holder 7; Be fixed with valve seat 6 on the cylinder 5, general air compressor factory all can produce.Connecting rod 3 of the present utility model is contained on the bent axle 2 by bearing pin 11, between connecting rod 3 and bearing pin 11, rolling bearing 12 is housed, on the connection end face of link 10 between cylinder 5 and the body shell 1, be evenly distributed with several recesses, on cylinder 5 and body shell 1, leave suction port 13 and 14 respectively.Front end at suction port is equipped with air-strainer 8.All can produce as general air compressor plant.The utility model air compressor belongs to the exhaust of big flow low-pressure one-level, Placement is directly to be connected with belt. referring to accompanying drawing 4: prime mover is by the vee belt drive pulley, bent axle 2 is rotated in crankcase, spur connecting rod 3 simultaneously, pass to transmission arm 4 at following powerful torque of the effect of connecting rod, transmission arm spurs rotor 4 again and does oscillating motion.Referring to Fig. 3: rotor is in the sealing cylinder, by suction port on the Aspirating valves platform, the air of inspiration is pressed onto rapidly in the air intake passage chamber, under the effect of Aspirating valves, air is pressed onto the chamber, exhaust passage, open in the channel lumens of sealing that outlet valve is pressed into exhaust box to the air of compression and outside relief opening is discharged cylinder. rotor swings in cylinder once, just finish a work cycle, so constantly swing, constantly pressurized air. use to supply with.Airintake wind-tunnel changes two-chamber into by single chamber, reduces impulse action, and secondary reduces delivery temperature, improves component working life greatly.
