German Desoutter shaft Desoutter model Desoutter price

Desoutter shaft is a shaft with very low rigidity, elasticity, and the ability to bend freely for transmission. It is used to connect two shafts with different axes, not in the same direction, or with relative motion to transmit rotational motion and torque. It can flexibly transmit rotational motion and torque to any position. It consists of a wire bundle with 4 to 5 layers of steel wire spirally wound on a central steel wire, with adjacent layers having opposite lay directions. It has a structure similar to single-lay steel wire rope, but with a very small lay pitch and a very large lay angle, and the outer layer of steel wires is mostly right-lay.

Desoutter shaft application

Flexible shafts are named after their use. In mechanical design, they are used as transmission components for non-linear transmission or transmission between non-coplanar planes. They can simplify transmission machinery while offering high transmission accuracy. They are widely used in various sectors, such as concrete vibrators, pneumatic picks, marine pumps, medical instruments, machine tool transmission devices, and automotive odometers, all of which can use flexible shafts for transmission. Additionally, flexible shafts can cushion shocks.

Desoutter shaft classification

Flexible shafts are divided into 3 types: wound type, universal joint type, and spring type. 1) Wound-type flexible shaft: Composed of a steel wire (or steel strip) shaft, a hose, and shaft connectors. The steel wire shaft is wound with 4 to 10 layers of high-carbon steel wire. The outermost layer is generally left-hand lay, and the torque is mainly borne by this layer. The shaft rotation direction should be such that this layer tightens (forward rotation); during reverse rotation, it can only bear about 15% of the forward torque. If the outer layer is tightly wound with thick steel wire, the torque capacity can be increased by 70 to 80%. The structure of the steel strip shaft is similar to that of the steel wire shaft. The hose is mostly made of formed steel strips rolled up, mainly used to store lubricant and prevent dust. Steel wire shaft connectors are used to connect two shafts, and hose connectors are used to connect the support parts of the two shafts. Connectors are integrated with the shaft and hose through welding or threaded connections, available in various connector types. 2) Universal joint-type flexible shaft: Composed of many connected shaft joints, including ball-tube joints and yoke-and-spider joints, etc., adaptable to shaft bending; the more joints, the greater the flexibility. 3) Spring-type flexible shaft: A long cylindrical helical spring, with various tools attached to one end for different operations; this type of shaft does not require a hose.

Desoutter shaft advantages

The advantages of flexible shafts include easy installation, compact structure, the ability to transmit motion and power over long distances, and ease of movement. They are mostly used for high-speed, low-torque transmission, such as driving portable sandblasters and grinders, automotive tachometers, and starting valves and switches of certain devices. However, flexible shafts have low torsional stiffness; if there are large changes in direction and significant torque fluctuations, the unevenness of the driven end speed is also large. Under normal conditions, the power transmitted by a flexible shaft does not exceed 5.5 kW; the torque without bending does not exceed 50 N·m, and the speed can reach 20000 rpm. During use, the speed depends on the shaft diameter and the bending radius during operation. Before use, the connectors must be securely fastened, and regular cleaning and lubrication are required. 1) The mandrel maintains a large contact area with the hole, resulting in higher positioning accuracy; 2) Uses the elastic deformation of the spring collet to center and clamp the workpiece, resulting in higher positioning accuracy; 3) The fit clearance of the positioning surface affects positioning accuracy; 4) Uses Pascal's principle to elastically deform the thin-walled sleeve for centering and clamping the workpiece, achieving high positioning accuracy with coaxiality reaching 5μm; 5) Can reduce clamping deformation of thin-walled sleeve workpieces, improving machining accuracy; 6) Has a positioning interference fit of 0.002mm, achieving extremely high positioning accuracy.
