Description

Technical Field

[0001] The utility model relates to a carbon fiber coupling. Background Art

[0002] Carbon fiber couplings are used in large processing machinery, especially the z-axis (equipment spindle) transmission of gantry machine tools. Large processing machinery is used to process hard parts, which needs to bear a large output torque and also needs to achieve a long service life. At present, the service life of this product far exceeds that of other brands on the market. It is more suitable for cutting more hard metals and even reduces the number of processing times for a single component, which may greatly improve the load performance of the equipment.

[0003] Secondly, the z-axis is the main axis of the equipment, and the main axis is connected to the motor in the vertical direction, so the z-axis also has a higher speed requirement. In the case of high speed, the speed is limited. In the case of low speed requirements, the torque can be increased to a higher level. For general large-scale processing equipment, since the output power of the motor is mature, the market demand for the processing speed of the main axis can actually reach 6000r / min. In the case of high speed, the rotation system of the equipment needs to have good dynamic balance performance (unit: g.mm / Kg). As an important component in the rotation system, if the coupling does not meet certain dynamic balance requirements, the customer will debug and test according to the maximum speed of the motor after the equipment is assembled, and the overall dynamic balance of the equipment is more likely to fail to meet the dynamic balance standards. Moreover, due to the different processing fields of the equipment, the spindle box has different lengths, so the change in length also makes it more difficult to ensure the dynamic balance index of the coupling. It is necessary to ensure the stability of the dynamic balance index of the coupling during the design and production of the coupling.

[0004] In the prior art, the diaphragm assembly cannot be disassembled relative to the carbon fiber intermediate body, so the dynamic balance cannot be calibrated independently, and the use requirements cannot be met when higher dynamic balance accuracy is required.

[0005] When the coupling parts are damaged, they can only be replaced by disassembling the whole or removing the diaphragm for replacement. The overall replacement cost is high, and disassembling the diaphragm for replacement will cause the accuracy to be lost after reassembly. The overall accuracy of the coupling cannot be guaranteed.
