Product Description

HangZhou ADVANCE HF/HI/HS cpp  propeller are widely used in CZPT engineering ships, tanker, dredger, public service ships, container vessels, tugboats and fish ships 

Based on shafting types, HF/HI/HS series CPP can be designed as multiple modes of single-engine-single-propeller, double-engine-double-propeller and double-engine-single-propeller etc. Through hydrodynamic calculation, structural design analysis, material well selection, the products are high in reliability, simple in structure and convenient in maintenance. Besides, the CPP system can be equipped with sorts of PTO via the transmission, to drive 1 or more load (shaft generator etc), thus satisfying demands of different hull forms and functions.

 

Features

1. Customized design: Since each ship has different hull forms, our engineers, based on the calculations of latest hydrodynamics theory and tank test results, will design the most suitable propeller on actual wake of each ship, ensuring best propeller efficiency with reducing vibration and noise as much as possible.

2. Serialization: Take use of FEM design tool to do optimization on blades and hub mechanism. Three CPP hub series that have been developed can satisfy ships with different hull forms. The hub diameter is up to 2m at maximum.

3. Low Pressure and Smoothness: Though successively optimizing and improving, the CPP system can produce a low oil pressure, thus increasing smoothness and reliability when blade adjusting pitch.

4. Integration: CPP control system based on PLC has very high flexibility and redundancy. With convenient visualized system setting, users may select control lever / DP system on demand.

5. Blade section geometry: Cooperated with Marin Company, it makes optimization to effectively reduce cavity, thus increasing propulsion efficiency.

6. OD-Box (Distributor): It is installed at front end of the gearbox, convenient to install, inspect and maintain.

7. Unique security design: In case of hydraulic trouble, pitch will be secured at the current position no matter at forward or backward condition.

8. Integration of hydraulic systems of CPP and gearbox: Save installation space and lower installation cost.

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 two 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 six 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, three 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.
