Brief Introduction

1. Screw conveyor is widely used for transporting powdery, granular, and bulk material. It mainly consists of tube (head/trail/hanging bearings, conveying spiral, housing, cover plate and base plate), inlet and outlet chutes, as well as driving device (electric motor, gearbox, coupling and base plate).

2. We provide 3 kinds of screw conveyors.
—GX series screw conveyor: 150/200/250/300/400/500/700mm screw diameter, with length from 3 to 70m, inclination angle below 20 degree.
—LSY series screw conveyor: 90/115/135/163/185/237/285/362mm screw diameter, with length up to 22m, inclination angle below 60 degree.
—LS series screw conveyor: 100/160/200/250/315/400/500/630/800/1000/1250mm screw conveyor, with length up to 70m, inclination angle below 20 degree.

Application Scope

1. Chemical, metallurgical, paper making, construction industries, etc.
2. Cement, concrete, coal dust, carbon black, soda ash, flour, grain, paper pulp, etc.
3. Specially suitable for field flowing work, such as concrete mixing station, bulk material transit storage, etc.

Characteristics and Performance

1. It has the features of simple structure, good sealing, large capacity, easy operation and low power invest cost.
2. Working temperature is -20~50 degree, with material temperature below 200 degree.
3. Axle head and conveying spiral adopt spline connection, with features of convenient mounting&disassembling, large load capacity and stability.
4. All sections of screw conveyor are connected with flange. Also screw blades are integral connection.
5. Inlet and outlet chutes have many kinds of connections, such as flange, sack, universal joint, etc.
6. ISO9001: 2008, CE certificate, SGS report

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.
