Component smooth rotation, and power input shaft 60 is measured with amesdial, it beats within 0.02mm；By two parts group above and below installation cavity
Dress together, is adjusted after fixing fixing seat, vibrating sensor 90, vibrating sensor bracket, vibrating sensor fixed frame, by mandrel
80 pass through damper 20 and driven gear 40 from the bottom up, and 80 upper end of mandrel and driven gear 40 are six side's shaft hole matchings, with double
Nut fixed central spindle is after 80s, using amesdial air plug gauge 80, beats within 0.03mm；Finally install driven gear, driven
Gear cap measures driven gear outer circle centre using amesdial, guarantees bounce within 0.02mm.
The principle of the invention is that the present invention mainly uses gear speed increaser and damper, realizes speedup function and damping
Function.Wherein gear assembly transmission ratio is 1/3.05, adjusts electric machine frequency by frequency converter, reaches different output experiment revolving speeds,
Damper uses rubber cushion assembly, reduces the influence to impeller overspeed testing machine, makes equipment speedup stage vibrated interference reduction.
Its action process is as follows, early period motor-driven belt, belt drives power input wheel 50, and power input wheel 50 passes through
Taper shaft hole matching drives driving gear 30, and driving gear 30 drives driven gear 40, and driven gear 40 is matched by six square shaft holes
Driving mandrel 80 is closed, mandrel 80 drives experiment impeller and its tooling.
It can be seen from the above description that the above embodiments of the present invention realized the following chievements:
1, due to using second level speed increasing mechanism of the invention, revolving speed increases, and vibration reduces, and the present invention is super relative to tradition
Fast testing machine revolving speed increases by 100%, and vibration reduces 30% under identical speed.
2, oil pocket divides upper layer and lower layer, using oil jet lubrication, is effectively prevented gear assembly immersion oil, and gear operation is avoided to generate
" stirring oil " phenomenon, the additional power for consuming motor；
3, power input shaft and power input wheel 50 use tapered shaft hole matching, realize axially driving and axially position, again
Guarantee dynamic balancing.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any to repair
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
