Problems solved by technology

[0002] The rotor body of the existing claw-type dry vacuum pump generally adopts a solid structure. Although it has a relatively good vacuuming effect and is widely used in the industrial field; but due to unreasonable structural design, there are still the following shortcomings: The rotor is a solid structure, relatively heavy in weight, and uses a lot of materials. The same size consumes a lot of power during operation, and the load on the shaft is large, so it is easy to deform. Because the structure of the rotor is eccentric, it is difficult to process dynamic balance. , longer processing time

Embodiment Construction

[0018] Referring to Fig. 1, a claw-type dry vacuum pump rotor has several reinforcing ribs 103 evenly distributed on the circumference between the shaft hole 101 of the rotor body 1 and the wall thickness of the outer wall 102, so that the rotor body 1 is hollow. Wheel-shaped, forming hub 104 and hub-spoke 105, the radial width of hub 104 is greater than the radial width of hub-spoke 105; Described several road reinforcing ribs 103 can be arc type, straight line or oblique line type, each The axial width of the inner end of the reinforcing rib 103 from the hub 104 is smaller than the axial width of the outer end from the hub 105, and the hollowed out part of the rotor body 1 is approximately trapezoidal slot 106, which can also be circular, elliptical, Quadrilateral or other polygonal shapes, etc.; the radial dimensions of the slots 106 are the same, but the axial dimensions are different in depth.

[0019] Referring to FIG. 2 , the slot 106 is partly shallow in the A-A axial ...

Abstract

The invention relates to a device of rotor with jaw dry-type vacuum pump. Between the axle hole and ectotheca distributing strengthening rib according to circle. Base on confirming the strength and fatigue life. The weight of rotor wide-range reduced at 1 / 2 to 1 / 3 of the past. The consumption of material reduced effective. Because of light weight, the rotor's operation cost less electric energy. The loading and deforming are lightness, make the operating life longer. Strengthening rib make process time of dynamic balance wide-range shorten, and confirm the balance better. The design make commercial batch process has great value in use and huge potentiality.

Description

technical field [0001] The invention belongs to the field of pumps and relates to a rotor of a claw-type dry vacuum pump. Background technique [0002] The rotor body of the existing claw-type dry vacuum pump generally adopts a solid structure. Although it has a relatively good vacuuming effect and is widely used in the industrial field; but due to unreasonable structural design, there are still the following shortcomings: The rotor is a solid structure, relatively heavy in weight, and uses a lot of materials. The same size consumes a lot of power during operation, and the load on the shaft is large, so it is easy to deform. Because the structure of the rotor is eccentric, it is difficult to process dynamic balance. , the processing time is longer. Contents of the invention [0003] The object of the present invention is to solve the disadvantages of the existing technical problems and provide a claw-type dry vacuum pump rotor with rib structure, which has light weight, g...
