Abstract
The utility model discloses a diaphragm coupling used for a natural gas compressor, and relates to a power transmission device between a driver and a compressor. The diaphragm coupling used for the natural gas compressor comprises a shaft end coupling half and a motor end coupling half which are located at two ends, a middle shaft located in middle, and two sets of diaphragms, wherein the two sets of diaphragms are arranged between the middle shaft and the shaft end coupling half and between the middle shaft and the motor end coupling half respectively, are fastened through pressing rings and pressing seats, and are fixed through bolts, nuts and gaskets. The diaphragm coupling used for the natural gas compressor has the advantages that transmission efficiency is high, a transmission part is long in service life, the reliability is strong, and transmission components are small in size, light in weight and small in starting torque.
Description
Technical field
The utility model relates to the actuating unit between a kind of driving machine and the compressor.
Background technique
Transmission of power between driving machine and the compressor can be divided into two big classes by traditional mode: direct connection transmission and non-direct connection transmission.Non-direct connection transmission (as belt transmission, big belt pulley serves as flywheel) mechanical efficiency is lower, generally about 95%, adds speed changer as the centre, and then efficient is lower; Direct connection gearing efficient is higher, generally can reach about 97%, but the coupling position between driving machine and compressor is provided with flywheel, with stabilized (steady-state) speed (except the micro-compressor).The volume and weight of its drive part of direct connection transmission of band flywheel is big, the starting torque height during compressor start (making heavy flywheel accelerate to the moment of torsion of rated speed from state of rest).
The model utility content
The purpose of this utility model is: propose a kind of diaphragm coupling for natural gas compressor, have the transmission efficiency height; The driving component life-span is long, good reliability; The transmission part volume is little, and is in light weight, the characteristics that starting torque is little.
The purpose of this utility model realizes by following technical proposals:
A kind of diaphragm coupling for natural gas compressor, the axle head half-coupling and the motor side half-coupling that comprise two ends, the jack shaft at middle part, and be located at respectively between described jack shaft and axle head half-coupling, the motor side half-coupling, and, bolt and nut fastening by retainer ring and pressed seat and two groups of fixing diaphragms of packing ring.
As optimal way, described nut is the nylon locking nut.
As optimal way, described diaphragm is built up by steel disc.
The beneficial effects of the utility model: the application's diaphragm coupling transmission is to adopt two groups of diaphragm transferring power that built up by stalloy between the input shaft flange of the output shaft flange of driving machine and compressor.Owing to adopted this finite elasticity element of diaphragm transferring power, effectively isolated most of fluctuation of speed of compressor, the remaining fraction fluctuation of speed also can come balance by the rotary inertia of rotor.Therefore, adopt diaphragm coupling as the power delivery mode of compressor, can omit flywheel part.Like this, both reduced the volume and weight of drive part greatly, the starting torque when having reduced compressor start again (making heavy flywheel accelerate to the moment of torsion of rated speed from state of rest).Simultaneously, the diaphragm coupling transmission also has very high efficient as a kind of novel kind of drive, and mechanical efficiency can reach 99.86%.Because there is not nonmetallic (as rubber) to reverse damper element, so the driving component life-span is all longer, reliability increases greatly.Has the transmission efficiency height; The driving component life-span is long, good reliability; Omit flywheel part, make the transmission part volume little, in light weight, reduce characteristics such as starting torque, be worth protection and popularization.
Description of drawings
Fig. 1 is the utility model embodiment's sectional view;
Among the figure, 1 is the axle head half-coupling, and 2 is bolt, and 3 is diaphragm, and 4 is packing ring, and 5 is nut, and 6 is jack shaft, and 7 is pressed seat, and 8 is retainer ring, and 9 is the motor side half-coupling.
Embodiment
Below in conjunction with specific embodiments and the drawings the utility model is further described.
As shown in Figure 1, a kind of diaphragm coupling for natural gas compressor, the axle head half-coupling and the motor side half-coupling that comprise two ends, the jack shaft at middle part, and be located at respectively between jack shaft and axle head half-coupling, the motor side half-coupling, and, bolt and nut fastening by retainer ring and pressed seat and two groups of fixing diaphragms of packing ring.As optimal way, as shown in this embodiment, nut is the nylon locking nut, and diaphragm is built up by steel disc (preferred 1Cr18Ni9Ti).
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
