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
The invention belongs to pump class field, relate to a kind of device of rotor with jaw dry-type vacuum.
Background technique
Existing device of rotor with jaw dry-type vacuum body generally adopts solid structure, though the reasonable effect that vacuumizes is arranged, and obtain using very widely at industrial field; But because structural design is unreasonable, also exist following deficiency: because rotor is a solid construction, weight is heavier relatively, and is many with material, and same external dimension are the power consumption height in operation process, and the load of axle is big, easy deformation; Because the structure of rotor is an eccentric structure, makes that the dynamic balancing difficulty of processing is big, process time is longer.
Summary of the invention
The objective of the invention is to solve the deficiency in the prior art problem and a kind of pawl-type dry vacuum pump rotor with reinforcing rib structure is provided, it is in light weight, and dynamic balancing is effective, and prolong working life.
The technical solution used in the present invention: a kind of pawl-type dry vacuum pump rotor, between the axis hole of its rotor body and the wall thickness of outer wall by being evenly distributed in stiffening rib.
Described rotor body is hollow wheel shape, forms propeller boss and axle spoke, and the radial width of propeller boss is greater than the radial width of axle spoke.
Described stiffening rib is camber or straight line or bias type, and the axial width of end distance axle is less than the axial width of outer end distance axle spoke in each stiffening rib.
The cut-out of described rotor body is the slotted eye shape of approximate trapezoid, or circle, ellipse, quadrilateral, polygon-shaped, and its radial dimension is identical, axial dimension depth difference, and top is shallow, the bottom is dark.
The forward and backward two-part slotted eye degree of depth of the turning handle of described rotor body is identical, is provided with stiffening rib therebetween.
The present invention compared with prior art has following actively useful effect:
1. by removing to reset meter cleverly, under the prerequisite of proof strength and fatigue life, reduced weight significantly, it is original 1/2 to 1/3 that weight is reduced to, and reduced raw materials consumption effectively;
2. because in light weight, its power consumption in operation process is reduced, the load of pump shaft is little, be out of shape for a short time, and arranged the relatively working life of length;
3. reinforcing rib structure design makes dynamic balancing shorten significantly process time, can guarantee better dynamic balancing simultaneously, makes industrialized mass production that very large use value and tremendous potential be arranged.

Embodiment
Consult shown in Figure 1, a kind of pawl-type dry vacuum pump rotor, between the axis hole 101 of its rotor body 1 and the wall thickness of outer wall 102 by several stiffening rib 103 that is evenly distributed in five equilibrium, make rotor body 1 be hollow wheel shape, form propeller boss 104 and axle spoke 105, the radial width of propeller boss 104 is greater than the radial width of axle spoke 105; Described some roads stiffening rib 103 can be camber, straight line or bias type, the axial width of end distance propeller boss 104 is less than the axial width of outer end distance axle spoke 105 in each stiffening rib 103, the cut-out of rotor body 1 is slotted eye 106 shapes of approximate trapezoid, also can be that circle, ellipse, quadrilateral or other are polygon-shaped etc.; The radial dimension of slotted eye 106 is identical, axial dimension depth difference.
Consult shown in Figure 2ly, described slotted eye 106 is shallow on the A-A of rotor body 1 axial dimension top, is 60-88mm, and the bottom is dark, is the 90-100mm degree of depth.
Consult shown in Figure 3ly, described slotted eye 106 is shallow on the B-B of rotor body 1 axial dimension top, is 10-40mm, and the bottom is dark, is the 90-100mm degree of depth.
Consult shown in Figure 4ly, described slotted eye 106 is shallow on the C-C of rotor body 1 axial dimension top, is 50-88mm, and the bottom is dark, is the 90-100mm degree of depth.
Consult shown in Figure 5ly, the D-D of the turning handle 107 of described rotor body 1 is identical to forward and backward two-part slotted eye 109 degree of depth, and axial dimension is 30-50mm, is provided with stiffening rib 108 therebetween, and stiffening rib 108 width are 5-15mm.
Because the model difference of rotor, its thickness, diameter also has nothing in common with each other, the degree of depth of cut-out slotted eye 106 and the thickness of rotor have direct relation, so, the degree of depth of slotted eye 106 also is different, each road stiffening rib 103 at each position of above-mentioned rotor body 1,108 positions that are provided with and the slotted eye 106 of formation, 109 degree of depth and layout, all consider the intensity and the dynamic balance performance of rotor body 1, by removing to reset meter cleverly, in the main performance that does not influence vacuum pump and under the prerequisite of proof strength and fatigue life, the weight of rotor body 1 is reduced significantly.
