Abstract
The utility model relates to a compressor without oil lubrication, which is mainly composed of a motor, a compression head, and an air storage tank, wherein, a piston back-and-forth movement component composed of a main shaft, a piston, a piston pin, a cylinder, a guide holder, a cam, and a linking rod is arranged in the compression head. The structure causes the piston to be free from the influence of side force in the process of converting the rotary motion of the main shaft to the back-and-forth movement of the piston, and thereby, the deflective abrasion and the mechanical vibration caused by the side force in the working process of a piston ring are avoided, and the service life and the reliability of the piston ring and the complete machine are enhanced.
Description
The utility model relates to a kind of non-lubricated compressor.
At present, non-lubricated compressor generally adopts crankshaft-link rod or eccentric rod gear to come to be converted into the to-and-fro motion of piston rotatablely moving.The connecting rod that this type games mechanism constitutes conversion of motion is a rigid connector.Thereby all be hard driving mechanism.Connecting rod is being converted into rotatablely moving of main shaft in the to-and-fro motion process of piston, because connecting rod and piston axis are an angle that is changing, can apply a bigger and lateral force that changing to piston.Thereby, can make piston ring produce eccentric wear, can make the piston ring choke-out in annular groove when serious, also can cause the vibration of compressor, influence the life-span and the reliability of piston ring and compressor.
The purpose of this utility model is the influence that provides a kind of piston can eliminate lateral force in to-and-fro motion for the deficiency that solves above-mentioned technology, avoids the eccentric wear of piston ring and the non-lubricated compressor of caused mechanical vibration.
In order to achieve the above object, the non-lubricated compressor that the utility model is designed, mainly comprise motor, compressing head, gas holder, in compressing head, be provided with the reciprocating motion of the pistons assembly, it is characterized in that described reciprocating motion of the pistons assembly mainly is made up of main shaft, piston, wrist pin, cylinder, cam and linkage rod, cam is fixed on the main shaft, and linkage rod is provided with slotted hole and is enclosed within on the main shaft, one end of linkage rod connects with piston by wrist pin, and the other end is arranged in the guide holder.Guide holder can be arranged on the right opposite of cylinder, and in order to reduce the sliding friction between linkage rod and the main shaft, can be provided with between linkage rod and main shaft can the free rolling roller.In order to reduce the sliding friction of cam and piston space, on piston, energy free rolling roller is installed by wrist pin, roller described here can be the roller of sliding bearing or rolling bearing or sliding bearing band outer ring or the roller of rolling bearing band outer ring.In order to make the linkage rod of an end in guide holder held stationary in to-and-fro motion, in guide holder, can be provided with guide pad, also be provided with spring between guide holder and guide pad, this spring can be cylindrical helical spring or tapered coil spring or butterfly spring or rubber spring.In addition, for the circular movement held stationary in the to-and-fro motion that is converted into linkage rod that makes cam, cam can be a kind of garden camber dish cam, comprising single garden arc disc cam and many gardens arc disc cam.
Above-mentioned reciprocating motion of the pistons assembly in compressing head, can be arranged to four row, six row, eight row to the dynamic formula type, like this, their single order, second-order inertia power and centrifugal force can both be offset, and can by select for use every pair to moving row and other right to suitable cam alternate angle between moving being listed as, make also complete equilibrium of moment, the spring force of system also can obtain balance, power is not constituted added burden.
The resulting non-lubricated compressor of the utility model is owing to adopted the reciprocating piston motion that rotatablely moving of main shaft is converted into ductility by guide cam mechanism, in whole motion process, because piston is not subjected to lateral force, thereby the eccentric wear of piston ring and the mechanical vibration that caused by lateral force by piston have been avoided, improve the sealing and the working life of piston ring, and then improved the reliability of complete machine.
Fig. 1 is the overall structure schematic representation of non-lubricated compressor;
Fig. 2 is the compressing head structural representation,
Fig. 3 is the linkage rod structural representation.
The utility model will be further described by embodiment below in conjunction with accompanying drawing.
As Fig. 1, shown in Figure 2, the described non-lubricated compressor of present embodiment, mainly by motor 1, compressing head 2 and gas holder 3 are formed, in compressing head 2, be provided with reciprocating motion of the pistons assembly 4, reciprocating motion of the pistons assembly 4 is mainly by main shaft 5, piston 6, wrist pin 7, cylinder 8, cam 9 and linkage rod 10 are formed, cam 9 is fixed on the main shaft 5, as shown in Figure 3, linkage rod 10 is provided with slotted hole 11, and be enclosed within on the main shaft 5, one end of linkage rod 10 connects with piston 6 by wrist pin 7, and the other end is arranged in the guide holder 12, and guide holder 12 is arranged on the right opposite of cylinder 8, can be provided with energy free rolling roller 13 in linkage rod 10 and 5 on main shaft, but between linkage rod 10 and wrist pin 7, be provided with free rolling roller 14, in guide holder 12, be provided with guide pad 15, between guide holder 12 and guide pad 15, be provided with spring 16.The described non-lubricated compressor of present embodiment, four row reciprocating motion of the pistons assemblies 4 are set in compressing head 2, and two pairs of alternate angles to the cam 9 between moving row are 180 °, design resulting non-lubricated compressor thus, in guide holder 12, slide and the slotted hole 11 at linkage rod 10 middle parts slides on main shaft 5 and realizes reciprocating guiding by guide pad 15, make piston 6 not be subjected to lateral force, when cam 9 is done " rise " motion, cam 9 pushes roller 14, finish the motion of calming the anger of piston 6, pressure spring 16 makes spring 16 accumulation of energys, and makes that the motion of piston 6 is soft simultaneously.When cam 9 is done " backhaul " motion, through linkage rod 10 pulling pistons 6, finish the air-breathing motion of piston 6 by spring 16 retracting spring power, so go round and begin again, finish suction, the exhaust process of compressor.
