Rotary Joints in Hydraulic Power Transmission
Hydraulic power transmission is a method of transmitting power using pressurized fluid, typically oil, to drive mechanical components. The motors, cylinders, and actuators are examples for mechanical components. Rotary joints transmit the fluid from a stationary part to a rotating part of machinery or equipment.
A rotary joint consists of a stationary housing and a rotating ring. These parts are connected by a set of seals. The stationary housing is connected to the fluid source. Then, the rotating ring is connected to the machinery. When the machine rotates, the ring rotates. Therefore the seals to move along with it.
The rotary joint transmits the pressurized fluid from stationary part to rotary part without leakage. The rotary joint ensures continuous flow of fluid. The leakage can cause of system failure, damage or accident. So this condition can cause costly repair. Therefore rotary joints are important for wide range of applications.
Where is the rotary joints in hydraulic transmission?
Rotary joint is preferred in a wide range of hydraulic power transmission applications. These applications can be broadly listed as follows:
