The present invention relates to a lubricating oil removal assembly of a steering engine, which is mounted on a piston rod of a steering engine to prevent lubricating oil from penetrating into the upper portion of the piston.

First, the structure of the steering engine and its operation will be described to help the present invention.

Cylinder (1) and crankcase (2) of the steering engine, a displacer (3) installed in the cylinder to reciprocate to move the working gas in the cylinder, and a displacer rod (4) fixed to the displacer (4). ), A piston 5 installed below the displacer, a piston rod 6 formed integrally below the piston, a crosshead 7 coupled to the piston rod below and capable of reciprocating in the crankcase 2, Crankshaft 10 for rotational movement by reciprocating movement of piston connecting rod 8 coupled to crosshead, displacer connecting rod 9 coupled to bottom of displacer rod 4 and piston 5 And an oil spatula 12, which serves to scatter the lubricating oil 13 while rotating together with the crankshaft 10 while being fixed to the piston connecting rod 8.

Therefore, when the piston 5 is reciprocated by the working gas in the cylinder 1, the energy is transmitted to the crank shaft 10 by the piston connecting rod 8, so that the crank shaft is rotated. Part of the movement is transferred to the displacer connecting rod 9 and used as energy to keep the displacer 3 reciprocating in the cylinder 1.

Meanwhile, when the crankshaft 10 rotates, the oil spatula 12 fixed to the piston connecting rod 8 pivots along with the crankshaft 10 to scatter the lubricant 13 upward, thereby piston connecting rod. (8) Lubrication of all moving parts in the crankcase (2), such as crossheads (7) assembled on the piston rod (6), as well as lubricating the joints of the displacer connecting rods (9) It also works.

However, in the steering engine described above, the working gas inside the cylinder 1 purifies the heat accumulator 14 and the cooler 15, so that the lubricating oil scattered by the oil spatula 13 is in the upper space of the piston 5. Invasion of the piston causes a fatal effect on the efficiency and lifespan of the heat accumulator and the cooler. The lubricating oil removal assembly which prevents this is inserted in the outer circumference of the piston rod 6 and the piston 5 and the crosshead 7 Assembled between them.

The lubricating oil removal assembly of the conventional steering engine has a housing 31, a scraper ring 32, two semi-circular oil absorbers 33, also approximately semi-circular, as shown in FIGS. The housing 31 and the reinforcement 34 are fixed to the oil absorber 33 by the wrench bolts 35.

The housing 31 is in the form of a ring and has an approximately "b" shaped cross section.

The scraper ring 32 is formed on one side of the incision, the inner diameter is slightly smaller than the outer diameter of the piston rod 6, the material is made of a small-bonded metal body with sufficient elastic force and pores.

The two oil absorbers 33 have the same shape, and the protrusions 33a are formed on the bottom surface thereof, and the inner diameter thereof is processed to be the same as the outer diameter of the scraper ring 32.

The two oil absorbers 33 have the same shape, and the protrusions 33a are formed on the bottom surface thereof, and the inner diameter thereof is processed to be the same as the outer diameter of the scraper ring 32.

The two reinforcements 34 also have the same semicircular shape and have a “b” shaped cross section, the inner diameter of which is processed the same as the outer diameter of the scraper ring 32, and the outer diameter of the protrusion 33a of the oil absorber 33. This reinforcement 34 is for preventing the scraper ring 32 from falling into the groove portion of the oil absorber 33 and maintaining the rigidity of the oil absorber.

The process of assembling the various kinds of parts as described above in the piston rod 6 will be described. First, the scraper ring 32 is opened and inserted into the circumferential surface of the piston rod 6, and then the housing from the lower side of the piston rod 6 is removed. When the two oil absorbers 33 are placed on the upper surface of the housing 31 while the 31 is inserted, the respective oil absorbers form a circle and the inner diameter portion is connected to the outer diameter portion of the scraper ring 32.

Then, the two reinforcements 34 are inserted into the protrusions 33a of the oil absorber 33, and the holes formed in the oil absorber 33 and the housing 31 and the reinforcement 34 are vertically aligned. After the wrench bolts 35 are combined, the assembly of the lubricant removing assembly is completed.

On the other hand, in the state where the lubricating oil removal assembly is assembled, the semi-circular oil absorbent body 33 and the reinforcing body 34 are assembled such that their connecting surfaces are perpendicular to each other, and the upper inner portion of the crankcase 2 as shown in the first diagram. It is put on.

Therefore, the lubricating oil 13 is scattered upward by the turning of the oil spatula 12, and the scattered lubricating oil is sprayed in the particulate state by the reciprocating motion of the crosshead 7, and the piston rod 6 and It rises along the outer wall surface of the crosshead (7), wherein the lubricant rod rising along the outer wall surface of the piston rod (6) and the crosshead (7) is scraped by the scraper ring (32) to fall downward. Then, the lubricating oil buried in the scraper ring 32 is absorbed into the oil absorber 33, and the sprayed lubricating oil is absorbed into the oil absorber 33 as it is.

Since the oil absorber 33 is a sintered alloy having an excellent oil absorption capacity and containing capacity, the oil absorber 33 can sufficiently absorb and retain the lubricating oil, and since the working gas can pass through the oil absorber 33, the lubricant when the volume changes in the cylinder is changed. No unnecessary pressure is generated by the removal assembly.

However, the conventional lubricating oil removal assembly has a problem in that the oil absorber becomes saturated during the operation of the device by absorbing the lubricating oil by only one absorbent.

In addition, when the oil absorber is saturated, it must be replaced with a new oil absorber, and it is difficult to check the lubricating oil absorption of the oil absorber from the outside of the device, so the replacement time is missed and the operation of the device is not stable. There was also.

The present invention was devised to solve such a conventional problem, and constitutes an oil absorber by the first oil absorber and the second oil absorber, and installs a viewing window so that a part of the second oil absorber is visible on one side of the casing. When the lubricating oil scattered by the turning of the oil spatula is sprayed by the reciprocating motion of the crosshead, the spray oil can be absorbed by the first oil absorber and the second oil absorber and the absorption state of the lubricating oil can be confirmed by the sight glass. Its purpose is to.

According to the present invention for achieving the above object, a casing connected between a cylinder and a crankcase, a first oil absorber inserted into the piston rod and supported in the casing, and a ring-shaped first connection connected to an upper surface of the first oil absorber. Provided is a lubricating oil removing assembly of a steering engine of the present invention, which is composed of a two-oil absorber and a viewing window installed on one side of the casing to identify a second oil absorber from the outside of the device.

Hereinafter, the present invention will be described in more detail with reference to FIGS. 4 to 5 of the accompanying drawings showing an embodiment as follows.

4 is an exploded perspective view of the main oil absorber and the second oil absorber constituting the lubricating oil removing assembly of the present invention. A casing 16 connected between the cylinder 1 and the crankcase 2, a first oil absorber 17 fitted to the piston rod 6 and supported in the casing 16, and an upper portion of the first oil absorber. A second oil absorber 19 elastically installed with a plurality of springs 18 so as to be hermetically connected, and a sight window 20 installed at one side of the casing 16 to identify the second oil absorber 19 from the outside of the device. And the secondary oil absorber so that the lubricating oil particles sprayed by the reciprocating motion of the crosshead 7 are first absorbed by the first oil absorber 17 and then secondarily absorbed by the second oil absorber 19. Absorbing lubricant The amount through the viewing window 20 allows a user to be identified on the outside of the equipment.

When the blade piece 21 is formed on the outer circumferential surface of the first oil absorber 17 so that the second oil absorber 19 is elastically connected to the blade piece 21, the outer diameter of the first oil absorber 17 is reduced. Since the inner diameters of the second oil absorber 19 and the second oil absorber 19 are also connected to each other, the connection area is widened so that the first oil absorber 17 is smoothly moved to the second oil absorber 19.

On the other hand, although the blade piece 21 formed in the outer peripheral surface of the 1st oil absorber 17 may be formed in one disc shape, it does not need to limit to this and may be formed in multiple numbers.

In addition, the first oil absorber 17 is made of a porous sponge or a porous metal sintered body in order to have a hygroscopic power, and the second oil absorber 19 is capable of secondarily absorbing the lubricating oil absorbed first by the first oil absorber 17. As long as the material to be able to be used, that is, the material having superior hygroscopicity than the first oil absorber 17, there is no problem in using any one.

Referring to the operation, effects of the present invention configured as described above are as follows.

When the crankshaft 10 rotates, the oil spatula 12 turns and the crosshead 7 reciprocates. At this time, the lubricating oil 13 is scattered upward by the turning of the oil spatula 12. The lubricated oil is sprayed by the reciprocating motion of the cross head 7 and continues to move upward in the particulate state.

The lubricating oil, which is formed as particles, and moves upwards, is inserted into the piston rod 6 and touches the primary oil absorber 17 supported in the casing 16 so that it can no longer be moved upward and is absorbed by the primary oil absorber 17 as it is. When the operation of the device is continued and the absorption of the lubricating oil in the primary oil absorber 17 is saturated, the lubricating oil is immediately transferred to the secondary oil absorber 19 and is absorbed secondarily by the secondary oil absorber.

In the above, the absorbed lubricating oil of the primary oil absorber 17 is transferred to the secondary oil absorber 19. The secondary oil absorber 19 connected to and installed above the primary oil absorber than the primary oil absorber 17. Absorption force is large, and a plurality of springs 18 are installed above the secondary oil absorber 19 so that the secondary oil absorber 19 receives the elasticity of the spring 18 and is hermetically sealed with the primary oil absorber 17. It is possible because it is connected.

In this way, when the amount of lubricating oil is also saturated in the secondary oil absorber 19, the secondary oil absorber 19 should be replaced immediately. In this case, the user may see through the see-through window 20 formed at one side of the casing 16. Since the saturation state of the secondary oil absorber 19 can be confirmed, the replacement time can be immediately replaced with a new secondary oil absorber without missing an exchange time.

Therefore, the present invention improves the removal power of the lubricating oil by absorbing the lubricating oil by the primary oil absorber and the secondary oil absorber and identifies the lubricating oil absorption state of the secondary oil absorber by the sight glass from the outside of the device. It can be exchanged, which makes it possible to achieve stable operation of the device.
