Abstract
The utility model discloses an integral flywheel body with the spoke having rectangular section. A wheel hub (1), a plurality of spokes (2), and a wheel flange (3) are produced into a whole, thus the assembly of the flywheel is convenient, the rotation precision is high, and the reliability is high; the spokes (2) adopt rectangular section structure, the length-width ratio of the rectangular section is about 1.3, thus not only the inertia/mass ratio is greatly enhanced, but also the flywheel has good processing performance; the quantity of the spokes (2) is optimally designed to be five, the comprehensive effect is optimal when the inclination degree of the spokes (2) is 9 degrees, and a plurality of bolt holes are arranged on both end surfaces of the wheel hub (1). The utility model has the advantages of simple and compact structure, convenient assembly, high inertia/mass ratio, small magnification factor during harmonic resonance, high rotation precision, secure and reliable flywheel performance, and ability of the intensity and the rigidity meeting the requirement on the flywheel mechanics environmental test condition.
Description
Technical field
The utility model belongs to the satellite control system technical field, and specially referring to a kind of spoke is the integral flywheel body of rectangular cross-section.
Background technique
Satellite the time need stand abominable vibration in emission, impact test, and its quality directly determines the cost launched, and emission back satellite needs operation reliably and with long-term under space environment, therefore requires satellite momenttum wheel good anti-vibration, and quality is little.
Be divided into two kinds of integrated and divergence types at present both at home and abroad on the satellite momenttum wheel wheel body structure collectivity of producing, the integrated structure is that bearing directly is installed on the flywheel body endoporus, and separation-type structure is that flywheel body is installed on the bearing unit.No matter be integrated or separation-type structure, its flywheel body is divided into disc type and two kinds of structures of spoke type again.Integrated web-type flywheel body structure is simple, compact, the running accuracy height, and the wheel body process industrial art performance is good, and amplification factor is little during resonance, but the flywheel body quality is bigger, therefore is applied to the less momenttum wheel of rotary inertia more; For the bigger momenttum wheel of rotary inertia, for obtaining bigger inertia/mass ratio, the divergence type I-shaped cross section spoked flywheel body structures that adopt more, it helps the standardization of products, seriation, the flywheel body quality is little, but flywheel body vibration amplification factor is bigger, needs to increase damped system for reducing amplification factor on flywheel body, its complex structure, technology capability are poor, and cost improves greatly.
Summary of the invention
At the problems referred to above, the utility model has designed the integral flywheel body that a kind of spoke is the rectangular cross-section, this integral flywheel body is assembled on the satellite momenttum wheel, can obtain bigger inertia/mass ratio, have and have less resonance amplification factor, simultaneously can greatly improve momenttum wheel running accuracy and reliability, reduce product cost.
In order to realize the foregoing invention purpose, the utility model has adopted following technological scheme:
Described spoke is the integral flywheel body of rectangular cross-section, be to be made into wheel hub, spoke, wheel rim as a whole, wherein spoke adopts rectangular cross section structure, the rectangular cross-section Elongation is about 1.3, the spoke number is 5, the spoke inclination is 9 °, and is provided with several bolts hole at two end faces of wheel hub.
Owing to adopted technological scheme as mentioned above, the utlity model has following good effect:
1, simple and compact for structure, easy to assembly, have higher inertia/mass ratio, amplification factor is little during resonance, the running accuracy height, the flywheel performance is safe and reliable;
2, with integrated web-type flywheel body structure mutually specific mass reduced 37%, bigger by 8% than divergence type I-shaped cross section spoke type architecture quality;
3, the amplification factor of integrated web-type flywheel body structure is about 14, i shaped cross section spoke type divergence type flywheel body structure is 70～80 as not adding the damping device amplification factor, add that amplification factor is 20～25 behind the damping device, and resonance amplification factor of the present utility model is about 16;
4, momenttum wheel adopts structure of the present utility model, its best results, and the intensity of flywheel body and rigidity satisfy the requirement of flywheel dynamic environmental test condition, and performance is safe and reliable.
Description of drawings
Fig. 1 is that spoke is the integral flywheel body structure schematic representation of rectangular cross-section;
Fig. 2 is the left view of Fig. 1;
Among Fig. 1: the 1-wheel hub; The 2-spoke; The 3-wheel rim.
Embodiment
As shown in Figure 1: spoke of the present utility model is the integral flywheel body of rectangular cross-section, is wheel hub (1), spoke (2), wheel rim (3) are made into an integral body, makes flywheel easy to assembly, running accuracy height, reliability height; Spoke (2) adopts rectangular cross section structure, and its rectangular cross-section Elongation is about 1.3, has both improved inertia/mass ratio greatly, has good processing properties again; Through optimal design spoke (2) number being set is 5, and spoke (2) inclination General the best when being 9 °, and is provided with several bolts hole at (1) two end face of wheel hub.
With the 8Nms momenttum wheel is example, adopt whole spoked flywheel body structure, the optimum radius of at first optimizing wheel rim is 101.5mm, flywheel body rim section quality is 1.5Kg, determine that the spoke number is 5,9 ° of inclinations are analyzed and verification experimental verification as calculated, spoke rectangular cross-section length and width are defined as 14mm, 11mm respectively, and its resonance amplification factor is about 16.Simultaneously through the intensitometer calculation and Analysis, the tensile stress that the rectangle spoke bears when the flywheel maximum speed is less than the minimum yield stress of 1Cr18Ni9Ti material, strength assurance coefficient is 1.7, and intensity and rigidity all satisfy the requirement of flywheel dynamic environmental test condition, and performance is safe and reliable.
Claims (1)
1. integral flywheel body that spoke is the rectangular cross-section, it is characterized in that: flywheel body is to be made into wheel hub (1), spoke (2), wheel rim (3) as a whole, wherein spoke (2) adopts rectangular cross section structure, the rectangular cross-section Elongation is about 1.3, spoke (2) number is 5, spoke (2) inclination is 9 °, and is provided with several bolts hole at (1) two end face of wheel hub.
