Balanced Spiral Retaining Ring

Product Description

Balanced 2-Turn Spiral Retaining Ring Internal


balanced feature statically balances the retaining ring. A series of slots, opposite the gap end, account for the missing material in the gap. This characteristic is very useful when the balance of the assembly is critical and it is necessary to reduce eccentric loading.

A balanced spiral retaining ring, also known as a balanced circlip, is a type of spiral retaining ring that has been specifically designed to reduce the centrifugal forces that are exerted on the ring during operation. This is achieved by creating a symmetrical, or “balanced,” design that distributes the forces evenly around the ring.

Balanced spiral retaining rings are typically used in applications where high speeds or heavy loads are present, such as in motors, gearboxes, and other high-performance mechanical systems. Because they are able to withstand these forces better than traditional spiral retaining rings, they can help to extend the life of the mechanical system and reduce the risk of failure.

When choosing a balanced spiral retaining ring, factors to consider include the diameter and width of the ring, the material it is made of, the load capacity, corrosion resistance, temperature range, and ease of installation. Additionally, it is important to consider the specific requirements of the application, such as the speed and load conditions that will be present, and the compliance standards of the industry.

In general, balanced spiral retaining rings are more expensive than the standard ones, but they can offer significant advantages in terms of performance and reliability in certain applications.

Classification of retaining rings

Spiral retaining ring is different from traditional stamping retaining ring, spiral circlips adopts winding manufacturing process for precise diameter size. They have a uniform cross section (anti-interference earless fit) and are free of burrs. Spiral circlips meet military and aerospace industry specifications and are used in thousands of mechanical products worldwide.

Ordinary snap-type retaining ring has ears on its structure, which cause interference with internal parts. The elastic spiral circlips made of stainless steel has a consistent cross-section without ears, so it will not interfere with matching parts after installation, and the cost of the retaining ring is lower than that of the cassette spiral circlips, the use of the retaining ring can save the pillow block design, reduce the size of the shaft, save materials and processing time.

A wave retaining ring is a removable spiral circlips with a wave shape. A wave retaining ring can replace a retaining ring and a wave spring, which can apply pressure to the ball bearing in advance, and is also assembled in the groove like a normal spiral circlips.

The double-turn offset type outer retaining ring is used to replace the pillow block. It is used to hold the nozzle part and make it easy to assemble. The width of the spiral circlips is designed for zero interference, and its outer diameter is smaller than the diameter of the thread root. In the pressure gauge, the wave spiral circlips is installed in the shallow groove, and only produces very little pressure on the surface glass. This retaining ring can not only fix the surface glass, but will not crush the glass.

The retaining ring forms side walls on both sides of the synchronous pulley. This method eliminates the press-in side wall. In order to facilitate the replacement of the belt, the retaining ring on one side adopts the easy-to-remove type. The wave spiral circlips is easy to meet the requirements of on-site maintenance. For example, the hydraulic cylinder seal when the ring needs to be repaired, the spiral circlips can be quickly removed with a screwdriver and easily reinstalled.

Features of balanced spiral retaining ring

The main features of balanced spiral retaining rings include:

  1. Symmetrical design: The ring is designed to be symmetrical, which helps to distribute the forces evenly around the ring and reduce the risk of failure.
  2. Reduced centrifugal force: The symmetrical design of the ring helps to reduce the centrifugal forces that are exerted on the ring during operation, making it more suitable for high-speed and high-load applications.
  3. Improved performance and reliability: The reduced centrifugal forces and symmetrical design of the ring can help to extend the life of the mechanical system and reduce the risk of failure, resulting in improved performance and reliability.
  4. High-speed and high-load applications: Balanced spiral retaining rings are typically used in high-speed and high-load applications such as motors, gearboxes, and other high-performance mechanical systems.
  5. Material: Typically made of spring steel, stainless steel, or other durable materials that are able to withstand the environmental conditions in which the ring will be used.
  6. Load capacity: The ring must be able to withstand the forces that will be exerted on it during normal operation.
  7. Corrosion resistance: If the ring will be used in an environment where corrosion is a concern, it should be made of a material that is resistant to rust and other forms of corrosion.
  8. Temperature range: The ring should be able to operate within the temperature range of the application.
  9. Compliance: It is important to check if the ring is compliant with any relevant industry standards or regulations, such as those set by ASTM, ASME, or ANSI.
  10. Balance: the ring is balanced, which means that the weight is distributed evenly around the ring. This ensures that the ring will not vibrate excessively and affect the performance of the machinery.
