Role and Classification of Clamping Retaining Rings Industrial Solutions

A clamping retaining ring is commonly used in mechanical transmission to clamp the connection between the shaft and bearing or shaft and fasteners. Its function is to ensure that mechanical parts are firmly connected and prevent loosening between the shaft and bearing or shaft and fasteners to ensure the regular operation of mechanical devices. According to the standard, "Clamping Retaining Ring" stipulates the terminology and definition of the clamping retaining ring, model labeling, fundamental size error, and other provisions; the role of the clamping retaining ring and the classification of in-depth analysis is as follows.

What is the function of the clamping retaining ring?

1. Clamping function: A clamping retaining ring can clamp the connection between the shaft and bearing or shaft and fastener to prevent them from loosening. Attaching rings generally use countersunk head bolts for fastening so that it is in close contact with other components of the equipment machine to ensure that the parts are closely connected.

2. Transfer load: The clamping retaining ring can also withstand and transfer the various loads generated by the equipment's operation, such as axial tension, radial load, torque, etc., to ensure the mechanical device's regular operation.

3. Adjustment function: The clamping retaining ring can adjust the clearance between the shaft and bearing or shaft and fastener by loosening and tightening bolts to realize the equipment transmission system's adjustment, calibration, and optimization.

What are the classifications of clamping retaining rings?

1. Spring Retaining Ring: The spring retaining ring realizes the clamping function through elastic deformation. There are two kinds of standard flat and coil spring retaining rings. Flat spring retaining rings are small and lightweight, have good resilience and fatigue resistance, and are suitable for high-speed bearing connections. The coil spring retaining ring is made of a coil spring with a simple structure and strong bearing capacity. It is ideal for high-load and low-speed connections.

2. Fixed Retaining Ring: Fixed Retaining Ring is a kind of retaining ring that realizes clamping function through a threaded connection, and there are two kinds of common ones, namely, bolt fixing retaining ring and nut fixing retaining ring. Bolted retaining rings are threaded through bolts and equipment holes to clamp shafts, bearings, shafts, and fasteners. The nut retaining ring is threaded to connect the nut with the clamping retaining ring, and the clamping retaining ring then clamps the shaft to the bearing or the rod to the fastener.

3. Locking Retaining Ring: A locking Retaining Ring is a kind of retaining ring that realizes the clamping function through the locking piece, and there are two kinds of common ones: flat locking retaining ring and conical locking retaining ring. A flat locking retaining ring consists of a flat locking piece and equipment with a hole composition, a fixed and reliable, simple installation, and other characteristics suitable for low-speed, significant torque connections. The conical locking retaining ring comprises a conical locking piece with a compact structure and adjustable tightening force, which can be used to connect a large-diameter shaft.

Through an in-depth analysis of the role and classification of the clamping retaining ring, we understand the function and types of connecting retaining rings. Hooking retaining rings are commonly used mechanical connection parts widely used in a variety of equipment and automatic transmission systems; their performance directly affects the stability of the operation of the equipment and life, so the selection and use of clamping retaining rings need to be based on the specific needs of the careful consideration of all aspects of the factors.
