What is retaining ring?
Retaining rings are thin, circular, metal components that can be either stamped from a sheet or coiled from wire.
What are retainer rings used for?
They are used in assemblies as a cost-saving solution … to avoid machining a shoulder onto a mating component. Retaining rings exist in many forms including, stamped, spiral or Spirolox, constant section, hoop, e-clip, beveled, and wave-ring forms.
How are stamped rings installed?
Stamped rings are installed with the help of a special tool — snap ring pliers. The pliers are inserted into the lugs to separate or compress the ends so the retaining ring can clear the shaft or bore. Stamped rings can replace cotter pins and other traditional fasteners in an array of applications.
What are the different types of flat wire rings?
Currently there are two additional types of flat wire rings, hoop rings and constant section rings . Hoop rings feature a narrow radial cross-section and a larger axial cross-section. They are installed into shallow grooves which makes them suitable for thin walled applications. In contrast, a constant-section ring is similar to a traditional spiral ring but is made from wire with a thicker cross-section and square edges. Constant-section rings are used in heavy-duty applications. Traditionally, both hoop rings and constant-section rings are single-turn.
What is a stamped ring?
Another version of stamped rings are e-clips. These rings are installed by pressing them radially onto a shaft groove. This can be a standard shaft or a stepped shaft. Similar to stamped rings, they become less cost effective as the required diameter increases in size. E-clips are used when it is preferable not to slide a ring along the axis of a shaft.
How to extract spiral rings from groove?
Instead spiral rings are wound one turn at a time into a groove. To extract a spiral ring from a groove, there is a removal notch that creates a gap between the end of the ring and the mating component. A blunt object (such as a screwdriver) can be inserted to pry the ring free.
What is a constant section ring?
In contrast, a constant-section ring is similar to a traditional spiral ring but is made from wire with a thicker cross-section and square edges. Constant-section rings are used in heavy-duty applications. Traditionally, both hoop rings and constant-section rings are single-turn.
What is a retaining ring?
Retaining rings are used to hold components onto a shaft or into a bore. The smooth, round finish of most shafts or bores makes them difficult to attach to with alternative methods, whereas retaining rings clamp around them and create a shoulder that keeps parts in place.
Why are retainer rings important?
Retaining rings serve an important purpose no matter what type of project they are installed in. These rings are one of the smallest and most inconspicuous components in the assembly, but are crucial to the performance as well, since they help to absorb vibration, split tolerances, or make the assembly as cost-efficient as possible.
What are the three types of retaining rings?
Smalley offers three types of retaining rings for use in your design— Spiral retaining rings, constant sections and Hoopsters® .
What are retention rings used for?
Retaining rings are also used in several other applications, such as fitness equipment, wind turbines, bearing retention, bicycles, doorknobs, gas pumps, office equipment, and many others. Retaining rings can be classified into three main categories based on design.
What is a spiral retaining ring?
Retaining rings — also known as snap rings or circlips — are metal fasteners installed into a groove on a shaft, or in a housing or bore to retain an assembly. The devices keep parts in place using a compact, lightweight design that requires fewer machining operations than other fastening techniques.
What is a spiral ring?
Spiral rings are made from flat wire that’s coiled two or three times around the circumference. They make a 360-degree contact within their groove and have a constant width around their circumference. Spiral rings are rarely designed with installation lugs but, instead, have notched ends that aid in their removal.
How big are retaining rings?
Retaining rings can range in size from 1mm to 1m in diameter. Different combinations of size, shape, style, and material result in designs that work in a variety of industries and applications. A standard automobile, for example, can have more than 50 retaining rings in systems including the powertrain, steering, and passenger safety.
What is constant section ring?
Constant section rings, in contrast, have the same width throughout their circumference. A stiffer cross-section results in contact at three points within the installation groove. These simple, easy-to-produce rings typically do not have lugs. Constant section retaining rings or snap rings.
Do spiral rings work?
Spiral rings tend to work well with high loads and, particularly, in applications where resilience to dynamic loading is necessary. Generally, spiral rings have lower RPM capabilities than tapered section rings. However, some designs like spiral rings with patented locking features, keep the product tightly in place.
Why is a retaining ring not easy to maintain?
For a retaining ring in a power tool, this is no easy feat as it is regularly exposed to high axial and vibrational force. The retaining ring must maintain its integrity, despite the various types of forces acting against it. Understanding why failure happens and how to prevent it is imperative. The consequences of retaining ring failure include ...
What causes retaining rings to fail?
Impact loading can also be a cause of retaining ring failure. It must be considered in both housing and shaft rings. As an impact load is applied, the shock causes the diameter of the ring to expand/contract, depending on whether it is a housing or a shaft ring. This change in diameter causes the ring to expand/contract out of the groove.
What is the maximum diameter of a retaining ring?
For a retaining ring with a diameter larger than 1 in., it is .010 in. maximum. If the radius on the groove bottom is too large, the ring may not engage properly and slip out of the groove.
How does groove depth affect radial wall?
Groove depth determines how much of the ring protrudes from the groove. The more the ring sticks out, the more of a moment arm there is, which results in a higher chance of the ring coming out. Smalley engineers recommend that at least one-third of the radial wall should be in the groove as a general rule of thumb.
What causes a ring to move out of the groove?
Similarly, cyclic loading and vibration can cause the ring to move out of the groove over time. Increasing the cling (interference fit between the ring and the groove) or using a heavier cross-section will help increase the radial force against the groove.
Why should the groove bottom be flat?
Groove Bottom. Ideally, the groove bottom should be flat so that the ring has the appropriate geometry for optimal cling. To allow for tooling capabilities or machining capabilities during the cutting of the groove, we have a recommended maximum groove radius.
What is retained component?
Retained Components. The retained component should have a relatively square corner and contact the ring as close as possible to the housing or shaft. A chamfer or radius on the retained component minimizes the ring contact, which can decrease the retention of the ring.
How a snap ring works
To understand a snap ring even better, let’s take a look at how it works. A snap ring or retaining ring has a C-shape or circular shape with a gap. The gap allows the ring to expand or compress.
Types of snap rings
There are many types of snap rings or retaining rings. They are classified broadly into 2 main categories: external snap rings and internal snap rings.
How to measure snap rings
As I said, internal circlips make contact on their external circumference. So, to measure their size, you measure the external diameter. Here is how to do it with vernier calipers.
How to install snap rings or circlips
There is more than one way to install a snap ring fastener. You can install it with a tool or without. Installing a snap ring without a tool means sitting the ring fastener in its groove by hand.
