Abstract

The present invention relates to a packing for preventing external leakage in the field of a rotating shaft (shaft) having a driving force in a closed state, and excludes non-metal packing and has a metal packing (metal sealing) with a metallic structure, there is no leakage and leakage even under thermal expansion or pressure It is about metal packing that can be semi-permanently packed. Specifically, the brass pipe and the brass rod casting are sealed in the cylinder or boss ring in the sealing process between the drive shaft having the power rotation force, that is, the blower shaft, the pump shaft, the drive shaft in the pressure tank or the vacuum tank, etc. It is machined with a wide cylindrical ring) and fixedly sealed to the packing part of the shaft to prevent the leakage and leakage in advance by protecting the shaft and the bearing by preventing the leak and leakage in advance even under high heat or pressure. Sealing is possible to protect, prevent wear and corrosion, and extend the life of machinery.

The present invention relates to a packing for preventing external leakage in the field of a rotating shaft (shaft) having a driving force in a closed state, and excludes non-metal packing and has a metal packing (metal sealing) having a metallic structure, there is no leakage and leakage even under thermal expansion or pressure It is about metal packing that can be semi-permanently packed. Specifically, brass pipes and round bar castings are used to seal cylinder pipes or round rod castings in the field of packing drive shafts with power rotation, that is, in the sealing process between the external drive of the drive shaft in a closed tank, such as a blower shaft, a pump shaft, a drive shaft in a pressure tank or a vacuum tank. It is processed with a boss ring (wide cylindrical ring) or fixedly sealed with a market product to prevent leaks and leaks by protecting the shaft and bearings in advance by rugged packing even at high heat or pressure, while gas or odorous substances do not leak out. Sealing is possible to protect the environment, prevent wear and corrosion, and extend the life of machinery.

In general, the external packing (sealing) of various rotary shafts in various sealed forms includes non-metallic material packing such as copper packing, ceramic packing, oil seal packing, and mechanical seal (carbon) packing. Tightening and replacement prevents leaks and leaks, so frequent tightening and replacement, and the shaft of the sealing part are abrasive, which reduces the life of the shaft and bearing due to corrosion caused by wear and leakage, while the metallic drive shaft receives heat to prevent thermal expansion. In this case, the non-metallic packing is not thermally inflated, causing a gap between the driving sealing parts due to shrinkage, which causes leakage, and the odor leaks out, which causes environmental pollution.

The present invention has been made with the following objectives to solve such a conventional problem.

An object of the present invention is to process metallic brass pipes and round bar castings into cylinders or maintenance rings (cylindrical rings) or market products in the airtight packing process of the drive shafts in a closed tank, such as a blower shaft, a pump shaft, a drive shaft in a pressure tank or a vacuum tank. By packing (sealing) the drive shaft bearings in the front of the power transmission unit, it prevents leaks and leaks in advance by protecting the shaft and bearings by preventing the leaks and leaks even under high heat or pressure, while gas or odorous substances do not leak out. It aims to be able to protect the environment and prevent corrosion to extend the life of machinery and so on.

In order to achieve the above object, the present invention excludes the packing that is tightened and replaced by packing presses with non-metallic packing such as copper packing, ceramic packing, oil seal packing, and mechanical (carbon) packing. To cope with the metal packing of brass structure, the bearing pre-stage of the power transmission device of the rotating shaft driven by the wide bosing (bushing) or the market driven by the wide shaft size according to the rotating shaft size with the brass pipe and the brass round bar casting As it is generally known to operate when the packing (sealing) is assembled on the front, brass (copper or bong or mixture thereof) has a very low loss even by friction caused by metal contact, thus extending the life.

Therefore, leakage and leakage are prevented by friction due to intimate metal contact, and are protected by a bearing of a later stage (back) and stabilized by being fixed by a bearing fixing frame or a supporting frame.

In addition, even when there is expansion by heat, the object of the present invention is provided such that it can be used semi-permanently without expanding the packing gap by expanding and contracting with heat transfer by close contact with a metallic material such as a rotating shaft structure.

Next, with reference to the accompanying drawings for the present invention described above will be described in more detail based on the preferred embodiment.

First, the metal packing of the present invention as a preferred embodiment, as shown in Figures 1 to 3, as shown in Figures 1 to 3 of the brass structure (11, 21, 31) of the copper shaft or a mixture thereof, the contact space of the axis into which the rotating shaft enters (10) , 20, 30, in contact with the rotating shaft and can be fixed by the steel structure (12, 32), or if there is a structure of the housing (fixing frame and packing space of the bearing) of the unitary boss ring as shown in FIG. Bushing) or dual boss ring (bushing) as shown in Figure 3 can be used by directly grafting can operate the rotating shaft.

Therefore, according to the present invention, the outer shaft of the driving shaft in the closed tank, such as the blower shaft, the pump shaft, the driving shaft in the pressure tank or the vacuum tank, which is a rotating shaft, is sealed, thereby preventing leakage and leakage, thereby protecting the rotating shaft and the bearing. The brass structures 11, 21, 31 of copper or column or its mixture are metallic and can be used semi-permanently.
