Abstract
The utility model discloses a kind of high stable type piston compressor eccentric discs, including compresser cylinder and driving motor, compresser cylinder inner cavity lower removable is plugged with connecting rod, the connecting rod lower end is fixedly installed with bearing, eccentric disc is fixedly installed in the bearing, inserting groove is offered in the middle part of the eccentric disc, activity is plugged with motor shaft in the inserting groove, and the motor shaft right end is provided with driving motor.Pass through the structure of eccentric disc, eccentric disc can be made both to be able to satisfy balance reciprocal inertia force, it can play the role of flywheel again, it is fluctuated simultaneously to make compressor not generate excessive rotation speed, flywheel is served as by eccentric disc, it is adjusted the speed using the effect of its energy storage, when there is being full of function in compressor, eccentric disc can get up extra energy absorption, when compressor occurs losing function, and the energy release that can be stored, to make up the deficiency of energy, compressor is operated in this way with even speed, reaches steady reliable, the effect improved service life.
Description
Technical field
The utility model relates to Compressor Technology field, specially a kind of high stable type piston compressor eccentric disc.
Background technique
Compressor (compressor) is a kind of driven fluid machinery that low-pressure gas is promoted to high pressure gas, is
The heart of refrigeration system.It from air intake duct sucking low-temp low-pressure refrigerant gas, by motor operate band piston to its into
After row compression, to the refrigerant gas of exhaust pipe discharge high temperature and pressure, power is provided for refrigeration cycle, due to piston compressor
The balance of inertia force and moment of inertia is one of the major issue in compressor design.Compressor during operation, can generate
Inertia force and moment of inertia need to add a balance weight to balance them.Further more, being exactly the rotational resistance that compressor also suffers from variation
Square causes additional dynamic load in the junction of movement parts, and perpendicular to crankshaft if the variation of rotational resistance square is excessive
Vibration is generated in plane, influences the intensity of parts.If motor directly drives, to cause pulsation of current and confession in motor
The voltage fluctuation of power grid, so that the normal operation of power grid and motor is destroyed, and act on driving moment and resistance mechanically
Torque is often the periodic function of driving link corner φ, and during compressor operation, kinetic energy can constantly change, so as to cause
The acceleration or deceleration of compressor during operation, has a machine in operation abnormal, influences service life of a machine.For this purpose, it is proposed that one
Kind high stable type piston compressor eccentric disc.
Utility model content
The purpose of this utility model is to provide a kind of high stable type piston compressor eccentric discs, to solve above-mentioned back
The problem of being proposed in scape technology.
To achieve the above object, the utility model provides the following technical solutions: a kind of high stable type piston compressor use
Eccentric disc, including compresser cylinder and driving motor, compresser cylinder inner cavity lower removable are plugged with connecting rod, the connecting rod
Upper end is fixedly installed with piston, and the connecting rod lower end is fixedly installed with bearing, and eccentric disc is fixedly installed in the bearing, described
Inserting groove is offered in the middle part of eccentric disc, activity is plugged with motor shaft in the inserting groove, and inserting groove bottom end left part is flexibly connected
There is fastening bolt, the motor shaft right end is provided with driving motor.
Preferably, the piston and the activity grafting of compresser cylinder inner cavity, and piston race diameter is equal to compresser cylinder
Intracavity diameter.
Preferably, the fastening bolt is mutually clamped with motor shaft.
Compared with prior art, the utility model has the beneficial effects that this kind of high stable type piston compressor is eccentric
Disk can make eccentric disc not only be able to satisfy balance reciprocal inertia force, but also can play the role of flywheel, be simultaneously by the structure of eccentric disc
So that compressor is not generated excessive rotation speed fluctuation, flywheel is served as by eccentric disc, is adjusted the speed using the effect of its energy storage, works as pressure
When function occurs being full of in contracting machine, eccentric disc can get up extra energy absorption, when compressor occurs losing function, and can be stored
Energy release, to make up the deficiency of energy, such compressor is operated with even speed, is reached steady reliable, is improved service life
Effect.
Detailed description of the invention

Every other embodiment obtained, fall within the protection scope of the utility model.
Please refer to Fig. 1-3, the utility model provides a kind of technical solution: a kind of high stable type piston compressor is eccentric
Disk, including compresser cylinder 1 and driving motor 7, the 1 inner cavity lower removable of compresser cylinder are plugged with connecting rod 2, connecting rod 2
Effect is to push 2 reciprocating operation of connecting rod by eccentric disc 3 and do manual work in compresser cylinder 1 with piston, 2 upper end of connecting rod
It is fixedly installed with piston 21, the piston 21 and 1 inner cavity activity grafting of compresser cylinder, and 21 race diameter of piston is equal to compression
1 intracavity diameter of machine cylinder, 2 lower end of connecting rod are fixedly installed with bearing 4, are fixedly installed with eccentric disc 3 in the bearing 4, partially
The effect of cartridge 3 is to serve as flywheel to make compressor not generate excessive rotation speed fluctuation by eccentric disc 3, utilize eccentric disc 3
The effect of energy storage adjusts the speed, and when function occurs being full of in compressor, eccentric disc 3 can get up extra energy absorption, when compressor goes out
When now losing function, and the energy release that can be stored, to make up the deficiency of energy, inserting groove is offered in the middle part of the eccentric disc 3
31, convenient for 5 plug fixing of motor shaft, activity is plugged with motor shaft 5 in the inserting groove 31, is driven by driving motor 7
Eccentric disc 3 operates, and 31 bottom end left part of inserting groove is connected with fastening bolt 6, convenient for eccentric disc 3 and motor shaft 5 is fixed
