Lubricating oil is leaked, and the maze is prevented. The pressure difference is reached, the pressure difference is reached - the money flow, the air flow is dust-proof by water [Prior technology] The labyrinth seal is also called a comb seal. It is a non-contact seal, end seal, or other dynamic seal front seal for a wide range of applications. The mechanism of the (four) of the two social divisions can be roughly divided into two media for liquid and gas, and the effect of hydraulic friction on the liquid; the thermodynamic effect on the gas. The friction effect is caused by the friction between the liquid viscosity and the labyrinth wall when the liquid flows in the labyrinth, so that the flow rate is slowed down and the leakage amount is reduced. The longer the labyrinth flow path, the more obvious the friction effect. The liquid along the flow path has a mixed effect, and the length of the former is related to the shape of the cross section, and the latter is related to the number of bends and geometry of the labyrinth. The labyrinth runner model consists of a throttle gap and an expansion cavity. The cavities are equal in volume. The thermodynamic effect is that when the gas enters the dilation cavity, the gas forms a strong vortex in the cavity, and the airflow rubs against the cavity. As a result, most of the kinetic energy of the airflow becomes heat energy, and the cavity can be a function of temperature and volume. The gas inside the cavity can gradually increase, and the airflow passes through the labyrinth process close to the isothermal process, when the process is equal. The gas internal energy plus the product of its pressure and volume is the enthalpy value. 'The cavity energy can be increased so that the pressure must be reduced. The gas flow is gradually reduced in each expansion cavity of the labyrinth. The pressure is reduced, indicating that the liquid leaks. The force is reduced and the purpose of leak prevention is achieved. Μ3Ό7704 Second.

When the rotation speed is high, the non-contact labyrinth seal can be used. At the free end of the working spindle u, because the diameter of the main shaft 11 is small and the line speed is low, the contact oil seal is used to seal the jade with the oil seal 52. Holding the tightness and improving the sealing effect, this design and the second In the comparison of the prior patents of Figs. (a) and (b), the labyrinth seal is mounted on the free end face of the work spindle u. The design is mounted on the fixed end face of the work spindle, and the free end face is mounted with the oil seal 'but the application is due to the work spindle For the high-speed centerless grinding wheel, the high speed, the free end face can also be changed to install the labyrinth seal. As shown in the fourth figure, the shaft seal seat 24 and the lock nut 42 are machined into the zigzag labyrinth ring because of its small diameter. The line speed is low, so the number of labyrinths must be increased to achieve a good sealing and waterproofing effect. The design industry has good marriage, can meet a variety of tool ages, and achieve waterproof and dustproof effect, such as this design is finer than the centerless grinding wheel spindle. Please refer to the plan view shown in the fifth figure. 'This design mainly provides the working spindle in this application example.
