The name of the seger rings comes from the name of the Seeger – Orbi company, located in Germany. The seger ring is a snap-on snap ring. It is a small element that has a wide range of applications. We can meet him in the processing industry, household, and automotive. It is mainly used to protect against axial displacement of other machine parts, thanks to which the remaining elements of the structure do not rub and may have a longer service life. In particular, the snap ring is the product of choice for blocking elements attached to shafts, axles or holes. Seger rings, thanks to their eccentric structure and various dimensions, perfectly adapt to special grooves.
Where can Seeger rings appear?
The seger ring is used in many industries, from industrial, machine to automotive. In the latter, it is used to protect pistons and pins in machine joints. Surprising information is the fact that the seger ring is also installed in household appliances where it is its actuating element.
Accessories, such as seger rings placed on shafts, axles or holes, have a wide range of applications due to the diversified diameter of the ring. The most common machine where there are rings are shafts, another name for journal rings. Shaft journals carry the torsional loads while rotating, and the embedded elements rotate with it. Most machine shafts have a stepped configuration, depending on the method of installation and strength. The shafts have journals intended for mounting bearings on them using a ring. The journal dimensions are from 8 to 1000 mm for holes, from 5 to 1000 mm for the dimensions of the shaft journal d. Most often, however, seger rings fit into the holes where the diameter dimensions are 300 mm.
What are the types of seger rings and their dimensions?
There are 2 types of seger rings, outer and inner rings, they are similar. The design by differs, however, in that the outer ring standard is defined as DIN471, with the ends extending outside the circle. Instead, the standard of the inner ring is DIN472, and the ends point inward, and you can see that the ring is open.
If you want to choose the size of the seger ringthat you currently need, appropriate measurements should be made. A special tool with two tips will be used for this. The first is shorter and is used to measure the diameter of the outer ring, and the second is longer and needed to measure the inside diameter. During measurements, the length and width of the rings should be determined, and the dimensions that will come out to us are determined in the following units: f h, max. b, d 1 f, d o g or d o min. The table with all possible dimensions will also be used to select the appropriate size of the rings.
How to remove the snap ring?
An important element is the proper assembly and disassembly of the seger rings. For this activity, you need to use a suitable tool, which is a serpentine pliers. It should be noted that there are two types, before you apply, read the symbol, because the outer ring pliers are different and the inner ring pliers. They often resemble ordinary pliers, but have a rounded tip. It is very important to use the right tool, because it will protect the rings and channels in which they are located. Covering the eyes plays a very important role during disassembly. Just a moment of inattention is enough and a badly caught ring may fly towards the operator, damaging e.g. eyes. It is essential to remove the rings slowly and with precision. In order to properly remove the seger rings, insert the pliers gently and deeply into the hole. Then we squeeze the handle so that the ring begins to gradually and evenly slide along its circumference. It is important to pull it out with the same force of pressure on the pliers, if you squeeze the pliers too much, the ring will break..
There are 4 types of seger tongs:
- internal straight
- internal bends
- external straight
- outer bends
Inner pliers are used for inner rings as evidenced by the name itself. Therefore, they are characterized by a slimmer structure compared to other types of tools. The outer pliers, on the other hand, are designed for outer rings and are distinguished by their more massive form. In addition, there is also a division into straight and curved violins. The former allow easy assembly and disassembly of spring rings, which are easily accessible. The bent pliers, as opposed to the straight ones, are used when the seger rings are located in hard-to-reach places.
When choosing the right tool, the size of the tongs should be taken into account, so that they are properly selected for the work performed. It is also worth paying attention to the handle, so that it is covered with a non-slip coating, which will greatly facilitate the comfort of work.
