What are shaft collars, locking rings and clamp hubs?
Shaft collars are mechanical components use to precisely set the axial position of shafts, bearings and other rotating parts. They are frequently used in machine construction, the automotive industry and other technical applications. Shaft collars typically consist of a ring with one or more slots and a screw. The screw is used to tighten or loosen the ring. By tightening the screw the shaft collar is fastened, accurately attaining axial positioning of the component. Shaft collars offer a simple and reliable approach of setting the position oof rotating components and can easily be adjusted or removed if required. The KIPP range includes shaft collars in various sizes, materials and styles to meet requirements of different applications.
By using a clamping ring components can be fixed in place. The locking ring allows for precise axial positioning at the same time. Operating parts are often used in mechanical engineering, the automotive industry and other technical applications. Locking rings typically consist of a ring-shaped body with one or more clamping elements that create a non-positive connection between ring and shaft or axle when tightened. This is usually done using screws or other fastening elements. Clamping elements in the locking ring apply equal pressure to the shaft providing secure gip and precise fixation of the component.
A clamp hub secures components such as wheels, gear wheels or other rotating elements on a shaft or axle. A clamp hub is often used in areas such as machine and vehicle construction. It consists of a cylindrical part with a central bore that fits onto the shaft or axle, as well as fastening elements that serve to mount the hub securely.
The difference between the three operating parts
Clamp hubs, just like shaft collars and locking rings, are mechanical fastening elements. Operating parts are used to fasten component on a shaft or axle. Despite having very similar functions, there are some differences between them.
The main difference here is the way in which they fasten and position components. Shaft collars are mainly used to precisely determine the axial position of components. So does the locking ring but compared to a shaft collar it often offers stronger fixation. Clamp hubs, on the other hand, are used to fasten rotating components.
While a shaft collar is a ring with one or more screws the component to be clamped is clamped in the locking ring. The inner diameter of the shaft collar limits the size of the component, which fastened by the screws. With locking rings, the ring-shaped body secures the component by tightening the body with the screws.
Clamp hubs consist of a cylindrical part with a central bore. These bores fit the shaft. To fasten the hub securely, they have additional fastening elements.
Types of shaft collars, locking rings and clamp hubs
The category "operating elements includes 12 different products. These are differentiated by the inside or outside diameter.
Locking rings
The KIPP range includes eight different locking rings.
- Locking rings slitted inside as well as wide locking rings slitted inside . Locking rings slitted inside provide forequal distribution of clamping forces. This results in a precise fit and high clamping forces without damaging the mating component. The shaft tolerance should be h11 or better. The wide locking ring has two grub screws.
- Locking rings slitted outsideare also available as wide locking rings slitted outside. The slit on the outside of the locking ring, compared to the one with the slit on the inside, allows for clamping forces of up to 15 % higher to be achieved. The bore remains cylindrical, in doing so precisely enclosing the shaft. The wide style has two grub screws.
- Slitted shaft collars with clamping lever Have a dimensionally accurate fit and very high clamping forces. The clamping lever allows for clamping and loosening of the locking ring with only one handle.
- Two-piece locking rings differ from conventional locking rings in that they are divided into two or more sections. The division allows for easier installation and disassemblywithout having to remove other components from the shaft. Locking rings made of A4 stainless steel additionally have a small centre point mark on the OD. The mark makes it easier to align and install the ring.
- Wide two-piece locking rings have to grub screws with hexagon socket. This type of locking ring can be used at temperatures of -40 to +175 °C. Thanks to their two-piece design wide two-piece locking rings permit simple and quick installation. Two-piece locking rings with an inner slit surround the shaft with equal distribution of clamping forces. This leads to precise fit and high clamping forces.
- Locking rings with thread Threaded locking rings can also be used in a temperature range from -40 to +175 °C. Threaded locking rings can be used on threaded rods or shafts with a thread tolerance of 6g. The thread surround the shaft with an equal distribution of clamping forces.
