Rock drilling tools manufacturer Prodrill produces shank adapters for most models of current prevailing rock drill machines. All Prodrill shank adapters are carburized, CNC manufactured, and made from premium steel. Thus ensure them with superior toughness and anti-fatigue strength to meet the most demanding drilling conditions. Moreover, all shanks could be produced with ether male or female threads if there is actually necessary.

HD709-T45-590 Drill Shank Adapter

 

Male shank adapters are generally better suited for drifting, tunneling and extension applications where high bending stresses are present. While female shank adapters are used when the drilling space is limited and the total feed length is important, for example underground roof bolting.

The task of the shank adapter is to transmit rotation torque, feed force, impact energy and flushing medium to the drill string (extension drill rods, drifting drill steels). 
Prodrill shank adapters are there fore designed to with stand the high impact power of modern rock drills and made from specially selected material which also is hardened through cauterizing. Around 300 different shank adapters suitable for different rock drills are currently available from CZPT series drifters, Tam rock series drifters, Garden Diver series drifters etc. 
 

Two flushing options of shank adapters: internal or external

– Internal flushing uses a water tube that fits through the center of the drill and into an o-ring seal in the end of the shank, to transfer flushing into the drill string

– External flushing, holes or a slot are required in the side of the shank adapter.These line up between seals inside the front head or water box of the rock drill, when the shank is installed. Flushing medium is supplied directly to this device and is introduced into the drill string through the shank

– External flushing is considered superior to internal flushing, as greater volumes of flushing agent can be delivered with less risk of leakage and hammer damage from water

The shanks for hydraulic drills and some pneumatic drills have external or front head flushing. Hydraulic shanks generally have at least 5 to 14-spline configuration,  Pneumatic shanks tend to have internal or through flushing and can generally be identified by their lugs or 4-spline configuration.

Standard Length Splined Shafts

Standard Length Splined Shafts are made from Mild Steel and are perfect for most repair jobs, custom machinery building, and many other applications. All stock splined shafts are 2-3/4 inches in length, and full splines are available in any length, with additional materials and working lengths available upon request and quotation. CZPT Manufacturing Company is proud to offer these standard length shafts.

Disc brake mounting interfaces that are splined

There are 2 common disc brake mounting interfaces, splined and center lock. Disc brakes with splined interfaces are more common. They are usually easier to install. The center lock system requires a tool to remove the locking ring on the disc hub. Six-bolt rotors are easier to install and require only 6 bolts. The center lock system is commonly used with performance road bikes.
Post mount disc brakes require a post mount adapter, while flat mount disc brakes do not. Post mount adapters are more common and are used for carbon mountain bikes, while flat mount interfaces are becoming the norm on road and gravel bikes. All disc brake adapters are adjustable for rotor size, though. Road bikes usually use 160mm rotors while mountain bikes use rotors that are 180mm or 200mm.

Disc brake mounting interfaces that are helical splined

A helical splined disc brake mounting interface is designed with a splined connection between the hub and brake disc. This splined connection allows for a relatively large amount of radial and rotational displacement between the disc and hub. A loosely splined interface can cause a rattling noise due to the movement of the disc in relation to the hub.
The splines on the brake disc and hub are connected via an air gap. The air gap helps reduce heat conduction from the brake disc to the hub. The present invention addresses problems of noise, heat, and retraction of brake discs at the release of the brake. It also addresses issues with skewing and dragging. If you’re unsure whether this type of mounting interface is right for you, consult your mechanic.
Disc brake mounting interfaces that are helix-splined may be used in conjunction with other components of a wheel. They are particularly useful in disc brake mounting interfaces for hub-to-hub assemblies. The spacer elements, which are preferably located circumferentially, provide substantially the same function no matter how the brake disc rotates. Preferably, 3 spacer elements are located around the brake disc. Each of these spacer elements has equal clearance between the splines of the brake disc and the hub.
Spacer elements 6 include a helical spring portion 6.1 and extensions in tangential directions that terminate in hooks 6.4. These hooks abut against the brake disc 1 in both directions. The helical spring portion 5.1 and 6.1 have stiffness enough to absorb radial impacts. The spacer elements are arranged around the circumference of the intermeshing zone.
A helical splined disc mount includes a stabilizing element formed as a helical spring. The helical spring extends to the disc’s splines and teeth. The ends of the extension extend in opposite directions, while brackets at each end engage with the disc’s splines and teeth. This stabilizing element is positioned axially over the disc’s width.
Helical splined disc brake mounting interfaces are popular in bicycles and road bicycles. They’re a reliable, durable way to mount your brakes. Splines are widely used in aerospace, and have a higher fatigue life and reliability. The interfaces between the splined disc brake and BB spindle are made from aluminum and acetate.
As the splined hub mounts the disc in a helical fashion, the spring wire and disc 2 will be positioned in close contact. As the spring wire contacts the disc, it creates friction forces that are evenly distributed throughout the disc. This allows for a wide range of axial motion. Disc brake mounting interfaces that are helical splined have higher strength and stiffness than their counterparts.
Disc brake mounting interfaces that are helically splined can have a wide range of splined surfaces. The splined surfaces are the most common type of disc brake mounting interfaces. They are typically made of stainless steel or aluminum and can be used for a variety of applications. However, a splined disc mount will not support a disc with an oversized brake caliper.
