Composition of harmonic transmission deviceThe harmonic transmission machine mainly consists of 3 traditional parts: wave generator, flexible wheel, and metal wheel. Wave generator: composed of flexible bearings and elliptical cams. The radio wave generator is always installed on the input end of the reducer, and the internal ring of the bendy bearing is fixed on the cam. The outer circle becomes an oval shape by means of forming beads. Flexible wheel: A bendy thin-walled elastic factor with an outer toothed ring, veritably installed at the output end of a reducer. Wheel only: The rigid ring section with an internal toothed ring, veritably with two extra gears than the comfortable wheel, is usually fixed on the reducer body.2、 Harmonic deceleration principleHarmonics are used as reducers, usually within the variety of lively wave generators, fixed inflexible wheels, and versatile wheel outputs.When the wave generator is put in into the internal circle of the flexible wheel, it forces the flexible wheel to suffer elastic deformation and form an elliptical shape, causing the teeth of the flexible wheel at its lengthy axis to be inserted into the groove of the inflexible wheel, fitting totally engaged; And the 2 wheel teeth at its brief shaft are completely out of contact and in a dry indifferent state. During the process of engagement to disengagement, it's in a state of dry engagement or engagement. When the wave generator continuously rotates, it forces the bendy wheel to constantly deform, causing the 2 wheel tooth to constantly substitute their respective operating states through the process of meshing, meshing, meshing, and detachment, resulting in the so-called staggered enamel motion, thus achieving the motion transmission between the lively wave generator and the flexible wheel.3、 Characteristics of harmonic drive1. High accuracy: Multiple teeth mesh simultaneously in two a hundred and eighty degree symmetrical positions, so the impact of gear pitch error and gathered pitch error on rotational accuracy is relatively average, leading to extremely excessive positional and rotational accuracy.2. Large transmission ratio: The transmission ratio of a unmarried degree harmonic gear drive can attain i=30~500, with a simple structure. Three basic substances on the same axis can obtain a excessive discount ratio.3. High load-bearing capacity: In harmonic transmission, the meshing between teeth is surface contact, and the variety of teeth engaged simultaneously is comparatively large, leading to a small unit subject load and higher load-bearing potential compared to other transmission forms.4. Small size and light-weight weight: Compared to bland gear devices, the amount and weight would be vastly reduced, achieving miniaturization and lightweight.5. High transmission performance and long service life.6. Smooth transmission, no impact, and coffee noise.Terms and definitionsStarting torqueThe minimum torque required to be utilized on the input finish when using a harmonic reducer for no-load startingOutput rated torqueThe output torque of a harmonic reducer that may function for a long time while retaining its ordinary functionality indicatorsPermissible top torque at birth stopThe allowable peak torque throughout startup and shutdown refers to the maximum affect torque of the harmonic reducer throughout startup or shutdownPermissible maximum average load torqueThe allowable maximum common load torque refers to the maximum torque that a harmonic reducer can function for a long timePermissible most instant torqueThe allowable most on the spot torque refers to the maximum torque that the harmonic reducer can withstand in a quick timePermissible maximum input speedThe maximum allowable input speed refers to the utmost allowable enter velocity of the harmonic reducerPermissible common enter speedThe allowable common enter pace refers to the typical cost of the input velocity of the harmonic reducerDorsal gapWhen the rigid wheel and enter end (wave generator) of the reducer are constant and ± 2% of the rated torque is utilized to the output end (flexible wheel), there will be a small angular displacement at the output end, which is expressed as backlash.Precautions on circular spline1.Mounting surfaces deserve to have enough flatness. smoothness, and no distortion.2.Especially in the area of the screw holes, burrs or international matter shouldn't be present.3.Please ensure the chamfering and avoidance machining are performed at the housingassembly, to bypass the interference with the round spline .4.The round spline needs to be rotatable in the housing. Be sure there is not any interferenceand it would not catch on anything.5. When mounting the bolt, make sure the bolt hole is true and aligned Bolts should rotatefreely when tightening and shouldn't have any irregularity due to bolt hole beingmisaligned or oblique.6. Don't tighten the bolts with the desired torque all at once. Tighten the bolts temporarilywith about halfthe specified torque, and then tighten them with the desired torque. Tightenthem in an even,crisscross pattern.7, Avoid pinning the round spline if probable because it can cut the rotational precision andsmoothness of operation.Precautions on flexspline1.Mounting surfaces need to have adequate flatness, smoothness, and no distortion.2.Especially within the subject of the screw holes, burrs or overseas matter should not be present.3.Please ensure the chamfering and avoidance machining are performed at the housingassembly, to bypass the interference with the circular splin.4.When mounting the bolt, make sure the bolt gap is right and aligned. Bolts must rotate freelywhen tightening and shouldn't have any irregularity due to the bolt hole being misaligned oroblique.5.Dont tighten the bolts with the desired torque all at once. Tighten the bolts briefly withabout half the specified torque, after which tighten them with the specified torque. Tighten them inan even,crisscross pattern.6Avoid unilateral meshing and deviation when assembling with circular spline.Rust preventionThe surface of the product has now not undergone rust prevention treatment. When rust prevention is required, please practice rust inhibitor to the surface. When our company needs to enforce floor rust prevention treatment, please seek the advice of customer support
