Problems solved by technology
This type of compressor and vacuum pump is sealed by a contact line between the blades and the cylinder body, so the sealing performance is poor, the output pressure is low, and there is a lot of friction between the blades, the rotor and the cylinder body during rotation, resulting in air motor The overall wear is fast, the life is short, and the efficiency is low
In addition, in order to ensure that the blades can safely enter and exit the rotor during rotation, the rotor must have a considerable diameter, so the displacement is bound to be small. Although there are double-blade air motors, since there are only two blades, the output torque pulsation is relatively large, and the output Too little torque

Embodiment Construction
[0037] The structure of the present invention is as Figure 13 As shown, the rotor 2 is located at the center, the housing 1 is located outside, the gas distribution cone 5 is located in the hollow circular table at both ends of the rotor 2, and the blade 3 is placed in the hollow ring (guide groove) at the opposite corner of the housing 1, and also It is located in the groove of the rotor 2 and forms an angle with the rotor 2. One plane of the vane 3 fits the side of the round table of the air distribution cone 5. The sealing strip 4 is located between the rotor 2 and the vane 3, and one side of the plane is in contact with the rotor 3 fit, one side of the circular table surface is bonded to the circular table surface E1 of the blade 3, and the spacer 6 is located in the hollow ring at the opposite corner of the housing 1, just filling the housing 1, the blade 3, the rotor 2 and the seal Article 4 forms the vacancy.

The invention discloses a vane type air motor which comprises a casing, a rotor, vanes, seal strips, air distribution cones and cushion blocks, wherein the rotor is arranged in the center; the casing is arranged outside; the air distribution cones are arranged in the hollow circular-truncated-cone surfaces at the two ends of the rotor; the vanes are arranged in hollow circular rings at the opposite angles of the casing and also arranged in the grooves of the rotor, and form angles together with the rotor; one plane of each vane is fitted with the circular-truncated-cone side surface of corresponding air distribution cone; the seal strips are arranged between the rotor and the vanes, one side of the plane of each seal strip is fitted with the rotor, and one side of the circular-truncated-cone surface of each seal strip is fitted with the circular-truncated-cone surface E1 of the corresponding vane; the cushion blocks are arranged in the hollow circular rings at the opposite angles of the casing, and gaps formed by the casing, the vanes, the rotor and the seal strips are just filled up with the cushion blocks. All sealed parts are face seal; the vane type air motor is large in discharge capacity, high in pressure, efficiency and specific power, compact in structure, easier to process, lower in cost, hard to wear and long in service life.
Description
technical field [0001] The invention relates to an air motor, in particular to a vane air motor. Background technique [0002] The structure of the existing vane air motor is that the rotor is placed eccentrically in the cylinder body, and the vanes are placed in the rotor radially or at a certain angle with the rotor radius. The body forms a sealed cavity, and the volume change generates pressure when it rotates. The number of leaves is two or more. This type of compressor and vacuum pump is sealed by a contact line between the blades and the cylinder body, so the sealing performance is poor, the output pressure is low, and there is a lot of friction between the blades, the rotor and the cylinder body during rotation, resulting in air motor The overall wear is fast, the life is short, and the efficiency is low. In addition, in order to ensure that the blades can safely enter and exit the rotor during rotation, the rotor must have a considerable diameter, so the displacem...
