characteristic

Flexible and adjustable: The expansion sleeve realizes the tensioning of the shaft by adjusting the position of the sleeve. This makes it suitable for applications where frequent adjustments or replacements are required, providing greater flexibility.

Simple and compact: the structure design of the expansion sleeve is simple, easy to disassemble, and can be reused. This makes it ideal for fixing shafts and parts in a small space.

Self-locking: The design of the tensioning sleeve makes it have better self-locking performance. This helps prevent the shaft from loosening or slipping, guaranteeing the stability and reliability of the connection.

material

Carbon steel: Carbon steel is one of the most common expansion sleeve materials. It has high strength and hardness and is able to withstand large loads and pressures. Carbon steel expansion sleeve is usually suitable for general mechanical transmission occasions, with good wear resistance and durability.

Alloy steel: Alloy steel is another commonly used expansion sleeve material, which adds some alloying elements to carbon steel to improve its hardness and corrosion resistance. Alloy steel tensioners are usually suitable for special conditions such as high temperature, high pressure or corrosive environments.

Stainless steel: Stainless steel tensioners have good corrosion resistance and are suitable for transmission systems in wet or corrosive environments. This material is often used in food processing, medical equipment and other fields that require high hygiene standards.

Special alloy materials: In some extreme or special working conditions, it may be necessary to use more advanced special alloy materials, such as titanium alloys, nickel alloys, etc. These materials typically offer higher corrosion resistance, high temperature performance and wear resistance.

performance

Tensioning performance: The design of the expansion sleeve enables it to realize the tensioning of the shaft, that is, by adjusting the position of the sleeve, the gap between the sleeve and the shaft is gradually smaller, so that the tensioning sleeve can firmly connect the shaft and the corresponding parts. The tensioning performance directly affects the stability and accuracy of the transmission system, which can effectively prevent the loosening or sliding of the shaft and ensure the reliability of the transmission.

Wear resistance: expansion sleeves are usually subjected to large loads and frictions in the transmission, so good wear resistance is required. The high-quality tensioner sleeve is made of material with good wear resistance, which can reduce wear and extend the service life during long-term work.

Corrosion resistance: Some expansion sleeve may be used in wet, corrosive environments such as offshore engineering, food processing, etc. In this case, the expansion sleeve needs to have good corrosion resistance to prevent corrosion from affecting the use effect.

Transmission efficiency: The transmission efficiency of the tensioner directly affects the energy conversion efficiency of the transmission system. Efficient expansion sleeve can reduce energy loss during transmission, improve transmission efficiency and save energy.

Self-locking: The expansion sleeve usually achieves the self-locking function through the design of the cone, so that the sleeve can be firmly locked on the shaft and prevent loosening or slippage during movement.

Load Carrying Capacity: expansion sleeves need to be able to withstand loads and torques between shafts and parts. Therefore, its carrying capacity is an important indicator of its performance.

Precision: The manufacturing accuracy of the expansion sleeve directly affects the matching accuracy between it and the shaft and parts, so for the transmission system with high precision requirements, it is necessary to choose the expansion sleeve with high manufacturing accuracy.
