Description

Coupling {COUPLING}

The present invention relates to a coupling for connecting a shaft for transmitting a driving force, and more particularly, to a coupling in which permanent magnet assembly is easy and an interlayer intermediary member is installed between the couplings for easy assembly and noise reduction.

A pump is a machine that transports a fluid through a pipe by using a pressure action. A pump is used to transport a liquid or gas fluid through a pipe by a pressure action, or a fluid in a low pressure container through a pipe to a high pressure container. It is a machine for pumping by. Water pumping, such as draining groundwater from mines and irrigation of agricultural water, has become a major problem, and several pumping devices have been devised. Today, pumps are usually used where fluids are used, from rural areas to mines, civil engineering works, factories and homes. Pumps are widely used not only for water but also for the transportation of petroleum, various chemicals, or special fluids such as pulp, viscose and sludge. The basic performance of a pump is represented by a head representing the height at which the pump can push up the liquid and a flow rate representing the volume of liquid that can be pumped out in unit time. Therefore, there are many types of pumps depending on the head, the flow rate and the type of liquid to be handled.

The present invention relates to a drainage pump for draining the water remaining in the foreign substance of the underground to the ground.

Such a conventional drainage pump is equipped with a drive device 1 for supplying rotational force to the upper portion of the pedestal 6, as shown in Figure 1 and 2, the drive shaft 2 of the drive device 1 is It is connected to the upper end of the coupling (3), and the driven shaft (4) is connected to the lower end of the coupling (3). Therefore, the rotational force of the driving device 1 is transmitted to the driven shaft 8 in a state in which the coupling 3 coupled to the two couplers 3a and 3b is coupled. The driven shafts 4, 8 extend through the pedestal 6 and penetrate the inside of the pipe column 7 and are connected to the impeller 11 of the casing 9. Reference numerals 5 and 10 denote bearings for supporting the driven shaft.

As shown in FIG. 2, when the driving device 1 is driven while two couplers 3a and 3b are coupled, the rotational force of the drive shaft 2 is driven through the coupling 3 to the driven shafts 4 and 8. ), And the impeller 11 is rotated accordingly. When the impeller 11 is rotated, since the casing 9 is submerged in water, the water is discharged to the ground through the drain pipe 12 by the pressure generated by the impeller 11.

The drive device 1 may use an engine using chemical fuel, or may use a motor using electricity.

The coupling 3 is configured such that two couplers 3a and 3b are coupled and disengaged. A tooth is formed at a lower end of the first coupler 3a, and a tooth engaging with the tooth is a second coupler 3b. It is formed to the upper end of the. Thus, the engagement and disengagement of the coupling 3 is determined by the engagement of the teeth of the two couplers 3a and 3b.

However, in the case of using such a drain pump, when the foreign matter contained in the water for draining is caught by the impeller, an excessive load is generated on the impeller, and the load is transmitted to the driving device so that the impeller and the driving device, etc. There is a problem that destroys or breaks down the components. In particular, when the impeller is stuck to the iron or stone, the impeller stops rotating, when using the motor as a driving device due to the overload has a problem that the coil of the motor burns out.

In addition, a buffer of silicone material is installed between the teeth of the coupling, and when the silicone wears out, there is a complicated trouble of periodically changing the silicone, and when operating in the worn state, the metal couplers collide with each other to generate a loud noise. There is a problem.

There is a coupling of a drain pump constituting a coupler having a permanent magnet developed to solve this problem. The coupling protects the components of the drive shaft by allowing the permanent magnet to be coupled to each other so that the coupling is naturally released when the load is severely applied to the driven shaft.

However, when the coupling is configured using such a permanent magnet, there is a problem in that disassembly and assembly are very difficult because of the strong magnetic force.

The present invention has been made in order to solve the problems according to the prior art, assembling the permanent magnet to the magnetic panel radially, and assembling the bearing panel to the magnetic panel so that the shaft can be fitted to provide a very convenient coupling in a simple configuration. Its purpose is to.

Here, when the bearing panels are bonded to each other by magnets, a slip sheet is installed between the bearing panels, and a groove in which a protrusion of the slip sheet is seated is formed in one of the bearings.

In addition, a groove is formed in each of the magnet panel and the bearing panel, and a spring fitted into the groove is provided.

In addition, key grooves are formed on the outer side of the central through hole of the magnet panel and the outer surface of the bearing portion so that the position thereof can be fixed when the bearing portion of the bearing panel penetrates through the central through hole of the magnet panel. It is characterized by.

Since the coupling according to the present invention can adjust the gap between the magnetic panel and the bearing panel using a screw, assembling and disassembling are made smoothly, and interlayer paper is installed in the middle to provide noise reduction effect.

In figure 3 a coupling according to the invention is shown. As shown, the coupling 100 includes a driving side coupler 110 to which the drive shaft 102 is fastened and a driven side coupler 120 to which the driven shaft 104 is fastened. The two couplers 110 and 120 are brought into contact with each other by the force of the magnet. Therefore, even if the driven shaft 104 does not rotate due to a problem in the driven shaft 104 side, the drive side coupler 110 does not affect the drive shaft 102 because it is turned. Of course, when the problem caused by the driven shaft 104 is solved, the driven shaft 104 is turned because the coupler 120 is stuck by the magnetic force.

Coupling 100 according to the present invention is composed of two couplers (110, 120) bar, one coupler 110 is made of a disk shape and a through hole (111c) is formed in the center of the hole 111c The through-hole is formed in the center so that the plurality of permanent magnets 200 are radially assembled, and the shaft 102 can be assembled, and the center through hole 111c of the magnet panel 111. The bearing part 112a which protrudes so that it may fit in the is formed, and consists of the bearing panel 112 in which the magnet hole 112b into which the magnets 200 and 300 enter is formed. Key grooves 111d and 112e are formed in the bearing portion 112a and the center through hole 111c, respectively, and the key 150 is assembled in the key grooves 111d and 112e to fix the position of each other. When assembling the coupler 110, it is very difficult to adjust its position due to the magnetic force. The key 150 and the key grooves 111d and 112e help the assembly by fixing the position during assembly.

The couplers 110 and 120 are composed of the magnet panels 111 and 121 and the bearing panels 112 and 122, and have the same structure as the driving side or the driven side. However, a groove 112d is formed in the rear side of the bearing panel 112 of the driving side coupler 110 to seat the protrusion 160a of the slipper 160 so that the protrusion 160a of the slipper 160 is seated. Of course, it is natural that the groove can be formed on the driven side.

Referring to FIG. 4, the magnet panels 111 and 121 are formed in a disc shape, and a plurality of magnets 200 and 300 are assembled radially on a rear surface thereof. The center through hole 111c is formed in the center of the magnet panels 111 and 121 so that the bearing portion 112a of the bearing panel 112 penetrates and is assembled. In addition to the center through hole 111c, four bolt holes 11a are formed on the outer side, and the holes 111a are formed to fit the bolt holes 112c formed in the bearing panel 112 to fasten the bolts 130. The magnet panel 111 and the bearing panel 112 are combined. In addition, two bolt holes 111b are formed to face each other around the bearing hole 111c, and this is where the distance adjusting bolt 140 is assembled. Of course, no hole is formed in the bearing panel 112 corresponding to the portion. Therefore, it is possible to adjust the distance between the panels (111, 112) by turning the distance adjusting bolt 140.

Referring to FIG. 5, the bearing panel 112 is also formed in a disc shape, and a portion in which a hole into which a shaft is fitted is formed to protrude forward to form a bearing portion 112a. In particular, the bearing portion 112a protrudes forward through the through hole 111c of the magnet panel 111. In addition, a groove 112d on which the protrusion 160a of the slip sheet 160 is seated is formed at the rear side.

When the distance adjusting bolt 140 is tightened, the end of the bolt 140 enters and pushes the bearing panel 112. Then, as shown in FIG. 6, the magnets 200 may be separated from each other easily. The assembly can of course be done in the reverse order.

9, grooves for accommodating the springs 180 are formed between the panels 111 and 112, and springs 180 are installed therebetween so as to be disassembled conveniently.
