Product Description

1. Revolutionary Innovation for Coupling

The successful development of hydraulic coupling is a great revolution to traditional coupling industry.

A. Where It Is Originated

Years ago, scientist Blaise Pascal found the law of liquid delivering pressure. Liquid will exert pressure evenly to the wall of its container who has a certain shape. By using this law, Beijing Baska Guanhua Technology Co., Ltd, the exclusive strategic cooperative partner of Sweden Baska in China, has successfully developed many high quality products. Today, we have developed a new generation productHydraulic Press Coupling, through combining Sweden Baska advanced technology and the characteristics of the market demand in China.

B. Application of the Law

Inject a certain amount of hydraulic medium into a bushing who has interlayer, and with the help of screw and piston or an external working pump, pressure will be evenly delivered to the contact surface of shaft and hub. With the influence of pressure, the bushing will expand evenly around the contact surface to generate an evenly distributed contact pressure. With applying the law, Baska hydraulic press coupling are featured by compact design, quick installation, easy positioning, small vibration, high transmission efficiency, no joint surface damage and quick removal. These characteristics will help clients to save more time and cost, creating more value.

2. Advantages of hydraulic press drum gear coupling over traditional couplings

A. Comparison with expanding-sleeve coupling

B. Troubles brought by traditional keyed-connection coupling

a. Traditional coupling transmits torque through various keyed connection. To those whose rated torque is comparatively large, the key groove will weaken the intensity and loading capacity of shaft. Under the certain working conditions, this can be solved by increasing the shaft diameter, which results the bigger equipment size and cost.

b. The installation and dismantling of traditional coupling is very hard and time-consuming. Forcibly removing the coupling may also damage the coupling and shaft, which will influence the normal operation of equipment and bring an economic loss.

All problems mentioned above can be well resolved with using hydraulic grid coupling.
