1. General Status:
Comparing with general worm transmission, Arccolumn worm transmission's contact linc benefits to dynamic pressure oil mcmbranc' s generation. During operation, lower oil temperature, stonger anti-aggludination capacity, stablc work, less shake, lower norse, higher transmission efficiency, excellent proccss technology. Arecolumn worm. Transmission is high technology product for widely application which is assigned by State. Arccolumn. Worm speed reducer is substitute designated by Mechanical Bureau. It has got Gb914788series worm red ucer standard. This worm speed reducer could be applied for reduced speed transmission for all different industrics, like: metallurgy. Mine, lifting, chemicals, light industry, construction ctc. It is substitute of the general speed redueers used for above in dustrics. The suitable work temperature is among40ºCtill+40ºC input speed is less than 1,500 rpm, worm could turn in forward and backward dircctions.
2. Installation, operation and maintenance of secd reducer:
a) Speed reducer should be installed on a stable place where it's convenient to fill or drain oil and good air circulation;
b) The original driver and working machine of speed reducer must be centralized, and the tolerance can't exceed acceptable data of coupler.
c) After installation the speed reducer could work flexible when turning by hand, no block.
d) After installation, speed reducer must have trial run without load before formal use, when the trial running successfully, then have trial with load as the following steps:
. With 25% of designed loading;
. With 50% of designed loading;
. With 100% of designed loading;
When every step trial run, wait the temperature reach to the balance point, and no less than 2 hours; the highest oil temperature can' exceed 100ºC;speed reducer run stably; no shock or noisc; lubricate weel, all sealing points and contact surfaces have no lcak.
e) Preventive maintenance should be applied regularly, once any scratches or agglutinations were found, they must be climinated effeetively, All spare parts must be manufactured as standard to cnsure good quality, Renewed spare parts can,t be uscd until trial with load is executed.
3. Lubrication of speed reducer:
a) This type speed reducer use lubrication oil generally.
b) When ambicnt temperature is lower than 0ºC, should use low viscosity oil. When ambient temperature is above 45ºC, should consider of cooling lubrication oil or decreasing load capacity of speed reducer.
c) Height of oil should reach lubrication window of speed reducer ease body.
d) Lubrication oil's replacement period
When the lst time to use new reducer(or renew worm wheel).new oil should be replaced after machine run for 714 days. In the following working life. Oil's quality should be cheeked periodically, once degenerative oil foumd should be replaced immediatcly.Generally, replace oil every month for continualiy working machine, replace oil every 8-10 months for those machinc working time less 8 hours per day.
Speed reducer should use original brand oil, can't mix with different brand or type of oil, and worm wheel shoud use same oil during exchanging oil, cleaning after heat.
e) For continually working speed reducer, oil temperature should be checked frequcntly when running. When oil tempcrature exceeds 100ºC, machine running should be stopped at once to investigate Reason. If surface teeth is scratehed or glued, maintenance should be made a.s.a.p, and lubrication oil need to be replaced.
4. This speed reducer's oil volume as following sheet for reference.

Oil volumc(L) | 1.6 | 2.7 | 4.7 | 6.7 | 8.8 | 16 |
5. Storage condition
Speed reducer could be stored indoor for 30 days, fill up speed reducer with recommended lubrication oil, and use bolt to replace acrator. Turn around couple set worm once very 30 days in order to protect oil scaling and bearing. When working, lubrication oil depth should be reduced to the corrct position, and acrator be re-installed. If the speed reducer had been stored indoor over one year or need to be removed to outdoor, machine supplier company should be contacted, and ask for extra user's manual.
a) If there is no oil inside spced reducer, woum wheel oil of N320 must be filled to correct oil positi on level as regulation before running. Under special ease(if can't found oil of N320. N320 gear whecl oil be permitted to use also), working load and transmission efficiency of speed reducer dccreasel.
b) N320 worm wheel oil and N320 gear wheel oil can't be mixed together.
c) Without permission, installed speed redueer can't be dismanted.
For those who haven't read our usage menu about how to install, Iubrieate and maintain mahine leading to damage of machine, our company would cancel quality assurance.
