Ventilator hub, particularly for large ventilators, has hub body, which is partially made of anisotropic substance, where hub body has rotation symmetric outer circumference and inner circumference concentric to outer circumference

摘要

The ventilator hub has a hub body (1), which is partially made of anisotropic substance. The hub body has a rotation symmetric outer circumference and an inner circumference concentric to the outer circumference. The hub body has blade bushings (10) for retaining of units for fixing ventilator blade to the hub body, where an axle clamp is connected with the blade bushings by multiple spokes (5). The hub body is made of oriented materials such as Dyneema(RTM: Ultra-high molecular weight polyethylene fiber), aramide, glass fiber or carbon fiber.
