Special Machinery Co. Ltd. Yuhuan fly - China

The company's FT-type series expansion sleeve (the taper-lock) is a non-bond linked structure, which is inside the jacket by the axial force under the effect of reduction in inflation and the outer shaft and hub to generate sufficient friction fit closely in order to transfer torque, axial force, so as to achieve the purpose of functioning institutions. Features: Join the centering performance is good; assembly without heating; dismantling or adjusting the relative position of shaft and hub to facilitate; no stress concentration; carrying ability. Usage: Hub and shaft coupling, through the bolt tightening effect after the play closed. Since the product is cone or a cone structure, movement through the axial force into radial force's role, resulting in friction to achieve the required

torque. Demolition will be all of the bolts can be loosened without having to remove the bolts, and then will fit within the hex wrench into the demolition of rotation of the bolt hole, the demolition of the top loose parts can be. Products are widely used in: construction machinery, textile machinery, mining machinery, metallurgy machinery, printing machinery, tobacco machinery, packaging machinery, forging machinery, rolling mill, all kinds of machine tools (machining centers, CNC machine tools with servo motor, stepper motor phase coupling) and mechanical transmission circuit.
