To install the planetary gear red↑↑∑ucer correctly, you must first underst↓β'and the reducer.
Working characteristics of NGW planetary gearε♠₽& reducer:
The gears are made of flexible high-stren±∞®gth low-carbon alloy steel by carburizinש★♦g and quenching, and the tooth surface hardness∞γ↓ reaches HRC54-62.
Using grinding technology, high ×'ε'precision and good contact.
The load capacity is high, which is seven γ>times higher than that of the gear reducer.
High transmission efficiency, up ↓₽✘to 98%, and long service life.
Structural features of NGW planetary ★®gear reducer:
NGW planetary gear reducer mainly consπists of sun gear, planetary ∏×gear, ring gear and planet c↔∑arrier.
In order to evenly distribute the ±©♥₽load of the three planetary gears, a toothed ↕©§™floating mechanism is used, that is,×<< the sun gear or the planetary car₽"rier floats, or both the sun gear a↓&nd the planetary carrier float at the same γ♦ time. The gears in the reducer are straight-t≥">oothed involute cylindrical gears. Has the follo↕←≥♥wing characteristics:
Small size, light weight, und↓er the same conditions, it is✔"€ more than 1/2 lighter than the ordinary involu♠↑>te cylindrical gear reducer, and the volume is₽™ 1/2 to 1/3 smaller.
High transmission efficiency: single-¶✘stage planetary gear reducer re♦€©aches 97% to 98%; two-stage planetary geaβ±r reducer reaches 94% to 96%; thre®♦e-stage planetary gear reducer reaches 91% '$↔to 94%.
The transmission power range is large: it can be∏± from less than 1KW to 1300KW, or even larger.
Large transmission range: i÷>=2.8～2000
Adaptable and durable.
Application and applicable conditions of planetarε<δ±y gear reducer:
NGW type planetary gear reducer has three horizonΩδ≤tal series, single-stage (NGW11-NGW121), two-€↔∑₽stage (NGW42-NGW122) three-sta≈$σ↓ge (NGW73-NGW123). Mainly used for metallurgy, m ≈ining, lifting and transportation ↔♠♥machinery and equipment, and can α also be used for power transmission under otεα♣her similar industrial and m'™ining conditions.
The working environment temperatur←★e is -40℃-45℃;
Correct installation and maintena≠∑♣₹nce of the planetary gear reducer is the key ÷$to ensuring the normal operation∑€ of the planetary reducer. Therefore, w©♣εhen you install the planetary gear reducer, ♥≥ be sure to install it carefully accorσσ★ding to the following installat↕>↑ion sequence.
Step 1: Before installation, it should be €♦confirmed whether the motor and ↓φ planetary gear reducer are in π↑Ωgood condition, and whether t§✔★he dimensions of each part adjacent to the¥×π♦ drive motor and the reducer are strictl ∑∏y aligned. This refers to t<επσhe size and common service between the po≥☆γ✘sitioning boss and shaft diameter "<of the drive motor flange and ©®the positioning groove and aperture of β←the reducer flange; wipe and dispose of the dσ≥irt and burrs on the same '>©surface.
Step 2: Unscrew the screw plugεΩ> on the process hole on the side o£€f the reducer flange, rotate the input end of the"♥•γ reducer, align the cap of the hexagon socket hea¥™×d cap with the process hol ±♠≠e, insert the hexagon socket head and loosen the δ★hexagon socket head cap screw .
Step 3: Hold the drive motor so that the k®'≠ eyway on the shaft is perpendiculδ©ar to the tightening screw of γ↑ε¥the input end hole of the reducer, and in> γ★sert the drive motor shaft into the input₹ end hole of the reducer. When ins∑¥★→erting, it must be ensured that the concentricity of the two is the same and the fαlanges on both sides are par₹¥allel. If there is a difference in heart rate ÷λor the flange on both sides do¥$es not bend, the reason must be found out.©λ¶✘ In addition, it is strictly forbidden to us★₩e hammering during installation, whi ∑₽ch can prevent the axial force or radial≥≠≥ force of the hammer from damaging the®₽≥ two bearings, and can determine★∞ whether the two are consistent through the ♦∏★feel of the installation. The key to determ≠'ining the common concentricity of the two and the¶π parallelism of the flanges is: after the ♥¶→two are inserted into each other, the flanges ↑↑πof the two are basically close to each other,∏↕ and the loopholes are the same.
Step 4: In order to ensure that the tw ¥↓o flanges are evenly conne←↓αcted to each other, first screw the dri×≤ £ve motor fastening screws freely, but ≥∑™do not tighten them; then g>™®radually tighten the four fastening screws acλ≥cording to the diagonal posit ×ion; finally tighten the planetary gears Tigh÷>✔∑ten the screw in the input hole of the ☆$∑reducer. Be sure to tighten th∏×e drive motor tightening screws first and then¶↕ tighten the reducer input hole tightening s✔§ crews.
Meticulous: The exact placementσ® between the reducer and the machine co↑nfiguration is similar to t₹"₩he exact placement between the planetary ∑±gear reducer and the drive motor. The key i∑☆↔∏s to ensure that the output shaft ♥ ∞±of the planetary reducer is aligned with the concσ ≈↓entricity of the input shaft of t≤¥™♠he driven sector.
