Description

Technical Field

[0001] The utility model relates to the technical field of pneumatic motor blades, in particular to a blade structure of a pneumatic motor. Background Art

[0002] Pneumatic motors, also known as air motors, are devices that convert the pressure energy of compressed air into rotational mechanical energy. Among them, vane-type pneumatic motors are one of the most widely used types of pneumatic motors.

[0003] The vane-type pneumatic motor is provided with a rotor and blades inside. When the motor is started, the blades will cling to the inner wall of the motor housing through centrifugal force, thereby forming an air cavity. However, currently the blades are directly placed in the slide groove of the rotor. When the air supply is just started, it is difficult for the upper blades to quickly contact the inner wall of the motor housing. Therefore, when it is just started, there is a problem of insufficient power or delay. Therefore, an improved technology is urgently needed to solve this problem existing in the prior art.

The end at which the non-magnetic alloy blade 2 is connected to the magnet B4 is provided with a plurality of second screw holes 8.

The second countersunk holes 9 correspond to the second screw holes 8 one by one and are connected by bolts, thereby realizing The connection and disassembly of magnet B4 and non-magnetic alloy blade 2, non-magnetic alloy blade 2 and magnet B4 are movably arranged in the slide groove 10 of non-magnetic alloy rotor 1, the magnetic pole of magnet B4 is close to the magnetic pole of corresponding magnet A3, the non-magnetic alloy rotor 1 is penetrated with axial hole 5 along the central axis direction, a keyway is arranged on one side of axial hole 5, and the axial hole 5 with keyway is used to realize connection with the central axis, and the central axis is the power output shaft, the length of non-magnetic alloy rotor 1 and non-magnetic alloy blade 2 is consistent, so as to ensure that when non-magnetic alloy rotor 1 and non-magnetic alloy blade 2 are installed inside the motor housing, and are limited by two end plates, non-magnetic alloy blade 2 will not swing left and right, the length of magnet A3 and magnet B4 is not greater than the length of non-magnetic alloy rotor 1 and non-magnetic alloy blade 2, so as to ensure that non-magnetic alloy rotor 1 and non-magnetic alloy blade 2 can be smoothly installed between the two end plates of pneumatic motor.

[0019] Assembly method and principle: First, the first countersunk hole 7 of magnet A3 is matched with the first screw hole 6 in the slide slot 10 of the non-magnetic alloy rotor 1 and fastened by bolts, so that magnet A3 is installed in the slide slot 10. Then, the second countersunk hole 9 of magnet B4 is matched with the second screw hole 8 of the non-magnetic alloy blade 2 and fastened by bolts to complete the connection between magnet B4 and the non-magnetic alloy blade 2. It should be noted that the polarity of magnet B4 needs to be installed in the opposite direction to the polarity of magnet A3, so as to achieve like-pole repulsion. Then, the center axis is passed through the shaft hole 5 of the non-magnetic alloy rotor 1, and then the non-magnetic alloy rotor 1 is eccentrically installed in the motor housing, and then the non-magnetic alloy blade 2 is inserted into each slide slot 10 of the non-magnetic alloy rotor 1 to complete the assembly.

At the same time, the cooperation of the magnet is more reasonable than the spring structure and has a longer service life.
