Description
Technical field
The present invention relates to the pneumatic motor in the Power Machinery Engineering, particularly, is a kind of magnetic type selfsealings blade pneumatic motor.
Background technique
Pneumatic vane motor is mechanical field a kind of dynamic power machine commonly used.Pneumatic vane motor commonly used at present, the quality of its service behaviour and its sealing are closely related with the blade that produces running torque.The blade release mode of pneumatic vane motor mainly contains following three kinds: the centrifugal force of blade self when one, utilizing pneumatic motor work, blade is released rotor; Two, through mounting spring formula blade ejecting mechanism, utilize spring force that blade is released rotor in the blade bottom; Three, the pressurized air that utilizes the blade bottom to feed is released rotor with blade.
There is following point in first kind of mode: when rotor speed was zero during the motor starting, the centrifugal force that blade receives was zero, and blade can not be pushed out, and can not form good Seal cage, thereby possibly cause pneumatic vane motor to start; When the pneumatic motor rotating speed is crossed when low; The centrifugal force that blade receives is too small; Sealing between blade and the stator inner surface also can be affected; These factors have a strong impact on the sealing between blade and the stator inner surface, cause a large amount of pressurized air to leak, and cause pneumatic vane motor starting performance and low speed torque performance to receive very big influence and waste pressurized air ability.
The problem that the second way exists: because the restriction of spring rate, it is stuck that blade takes place the motor that has a spring blade ejecting mechanism at work easily, influences motor operations; Perhaps, cause blade and stator inner surface frictional force excessive, have influence on motor operations performance and efficient; Moreover because motor runs up, under long-term loading, spring can lose efficacy because of tired.
The problem that the third mode exists: when the compressed air pressure that feeds when the blade bottom was crossed and hanged down, the thrust that blade receives was less, and blade and stator inner surface sealing are affected, even it is logical to cause the high low pressure air to scurry, and cause motor to lose driving force; When compressed air pressure is too high; The thrust that blade receives is excessive, and the frictional force of blade and stator inner surface increases, and causes the resisting moment increase of pneumatic motor and causes the blade wear aggravation; And the processing of the compression air flow channel of blade bottom acquires a certain degree of difficulty, and operability is affected.
