Abstract
The utility model relates to a diaphragm coupler, which is characterized in that a diaphragm is arranged at two sides of an intermediate section, the outer side of the diaphragm is provided with an isolation sleeve and a connection disc, the connection disc is provided with a buffering ring, the connection disc is fixedly connected with a motor half pivot journal through a connection bolt, and the other end of the connection disc is connected with a half pivot journal of a compressor. Since two ends of the intermediate section are provided with the connection disc with the buffering ring and by utilizing the effect of the buffering ring on damping the vibration system, the natural frequency (omega n) of the coupler is reduced, and the power amplification coefficient of the coupler is reduced; at the same time, the buffering ring also plays the effect on preventing the vibration, so the vibration is minimized. A midbody has the safety protection function, so once the diaphragm and the bolt are broken, the midbody is still remained inside the coupler and is free from being thrown out, thereby, no serious accident can be caused.
Description
Technical field
The utility model relates to a kind of mechanical transmission component, relates to a kind of diaphragm coupling specifically.
Background technique
In refrigeration industry, the diaphragm coupling that the helical-lobe compressor unit uses is the intermediate member that connects motor and compressor drum, is the device of transmitting movement and power and compensation three direction displacement in the unit, is the key element that influences whole unit vibration and noise.Common diaphragm coupling, as shown in Figure 2, couple together by the articulation hole bolt by two ends semiaxis joint, middle segmentum intercalaris, diaphragm unit, there are matching gap in bolt and link, therefore the balance and the interchangeability of coupling are relatively poor, the resiliently deformable that only depends on diaphragm to produce in addition in operation process reduces vibration, and its effectiveness in vibration suppression is relatively poor, causes equipment acoustic noise higher.Because diaphragm or bolt fatigue fracture, make that segmentum intercalaris flies out in the coupling of high speed rotating, can cause serious accident.
Summary of the invention
At the defective that existing diaphragm coupling exists, the utility model provides a kind of and makes the unit running steadily, vibrate little, noise is low, the diaphragm coupling of security of operation.
Solving the problems of the technologies described above the concrete technical measures of being taked is: a kind of diaphragm coupling, it is characterized in that: diaphragm (6) is housed in middle segmentum intercalaris (4) both sides, in diaphragm (6) outside spacer (8) is housed, in spacer (8) outside land (3) is housed, on land (3) mesopore, buffering ring (2) is housed, in middle segmentum intercalaris (4) through hole, clamping sleeve (9) is housed, clamping bolt (5) passes the through hole on middle segmentum intercalaris (4) one end through holes and the land (3), fastening with nut (7), by fixedly connected dish of connecting bolt (10) (3) and motor semiaxis joint (1), the other end land (3) is fixing with compressor semiaxis joint (11).
Beneficial effect of the present invention: because the land of tapedbuffer loop is housed at middle segmentum intercalaris two ends, utilize the damping of buffering ring to vibration system, reduce the natural frequency (ω n) of coupling, reduced the coupling dynamic magnification factor, buffering ring has also played the effect of separating vibration simultaneously, and it is minimum that vibration is dropped to.Intermediate has safety protection function, in case diaphragm and bolt fracture, intermediate still rests in the coupling, can not throw away, and can not cause serious accident.

Fig. 2 is existing diaphragm coupling structural representation.
Embodiment
Accompanying drawings structure of the present utility model.
A kind of diaphragm coupling, as shown in Figure 1, in order to improve the damping capacity of diaphragm coupling, must increase its damping constant, mainly take to increase the way of disturbance torque frequency (ω) and eigentone (ω n) ratio, when ω/ω n increased, the dynamic magnification factor of coupling diminished, thereby reaches effectiveness in vibration suppression.The structure of coupling is: in middle segmentum intercalaris 4 both sides diaphragm 6 is housed, in diaphragm 6 outsides spacer 8 is housed, in spacer 8 outsides land 3 is housed, on land 3 mesopores, buffering ring 2 is housed, the buffering ring material is a rubber, utilize the damping of buffering ring to vibration system, reduce the natural frequency (ω n) of coupling, reduced the coupling dynamic magnification factor, buffering ring has also played the effect of separating vibration simultaneously, and most of vibrational energy is cut down, and is converted into the potential energy of deformation of buffering ring, thereby overcome resonance, it is minimum that vibration is reduced to.In middle segmentum intercalaris 4 through holes, clamping sleeve 9 is housed, clamping bolt 5 passes the through hole on middle segmentum intercalaris 4 one end through holes, diaphragm 6 through holes and the land 3, with nut 7 they are carried on the back tight composition intermediate, land 3 on the intermediate is fixing with motor semiaxis joint 1 by connecting bolt 10, and intermediate the other end land 3 is fixing with compressor semiaxis joint 11.Nut is connected with land and diaphragm, guarantee that absolute no backlash cooperates, original rivet and riveting ring have been cancelled simultaneously, dwindled the stressed aperture of diaphragm, nut directly contacts with diaphragm, has improved the coupling bearing capacity greatly, also can be according to demand, quantity by the change diaphragm obtains different transmitting torques, centering capacity reaches each to rigidity, and under the same working condition, coupling can dwindle a specification at least.
