Application Differences And Advantages And Disadvantages of Clamping Type And Expansion Set

The two structural principles and common ground

Cpped synchronous wheel:

It usually holds the synchronous wheel and shaft firmly by the the device or structure.

Banded and tight set of synchronous wheel:

The fastening force of the bolt connection is converted to the surface pressure on the inner diameter side,

Hold the synchronization wheel to the shaft.

In common:

No need to extra shaft key groove or flat, will not reduce the strength of the shaft, can meet most use occasions, installation and disassembly convenient.

Advantages and disadvantages of gritype synchronous wheel

Advantages of the clamped synchronous wheel:

Installation and disassembly is simple and fast, high maintenance frequency or often need to replace the synchronization wheel is more advantageous.

Disadvantages of the clamped synchronous wheel:

In order to ensure the concentricity and coordination accuracy of the wheel and shaft, it may not be as good as the tight sleeve synchronous wheel, the transmission accuracy is relatively low, the structure is relatively not compact enough, and the space is not too narrow scene.

Advantages and disadvantages of expansion and tight set synchronous wheel

Advantages of the expansion and compact set of synchronous wheel:

It can better ensure the same comfort and coordination accuracy of the wheel and shaft, so as to provide more stable and accurate transmission, suitable for high precision transmission, compact structure, suitable for small space scene.

Disadvantages of tight synchronous wheels:

The installation and disassembly is relatively complex, not as fast and convenient as the clamped synchronous wheel.

The difference between holding type and expansion type

Installation and disassembly aspects:

The installation and disassembly of the clamping type synchronous wheel is relatively simple and quick.

The expansion and compact synchronous wheel may be slightly inferior in the ease of installation and disassembly.

Application scenarios:

Clamp type synchronous wheel is more common in general transmission scenarios.

Because of the compact structure, the synchronous wheel is more suitable for the environment with small space

Transmission performance aspects:

The synchronous wheel relies on the expansion and tight sleeve to provide uniform and large holding force, so that the synchronous wheel is closely connected with the shaft, which can reduce the relative movement and vibration of the shaft and the wheel, ensure the accurate and stable transmission, usually the transmission accuracy and stability are better.

The clamping type synchronous wheel closely connects the wheel and the shaft through the clamping force, and its transmission accuracy and stability are slightly inferior to that of the expansion and tight sleeve type, which is suitable for the scene with medium transmission accuracy and stability requirements.

Maintenance frequency aspect:

When the equipment often needs to replace the synchronous wheel or has a high maintenance frequency, the clamped synchronous wheel may be a better choice.

Cost:

The clamping synchronous wheel has simple structure and low manufacturing cost;

The structure and manufacturing process of the expansion and tight set are complex, especially the high quality expansion and tight set, and the material and processing cost are high.
