1 Preface
The enclosed instructions review the transportation, storage, assembly, usage and maintenance of Kuma worm speed reducers, etc.
2 Safety Notes
•
Please read the instructions carefully before operation of the gearbox and present the instructions to the user for proper usage and care.
•
Following the instructions in the manual is a prerequisite for the trouble-free operation and long operating life, which also helps avoid
personnel injury and property loss.
•
Whenever the worm gear reducer has any abnormal phenomena (like temperature increasing, noise level, vibration in an improper level)
during the operation, please urgently stop the reducer and check the cause. The machine should stop operation until the cause is deter-
mined and the conditions are eliminated. Please consult our service department if you have any questions.
3 Transportation
•
Once you received the shipment, please inspect items. In case any damage occurred, please don’t use the product and inform the trans-
port company immediately.
•
Before mounting the reducers, please tighten the eyebolt which is selected according to the weight of reducers and can’t bear additional
weight. If there is additional load, please select proper device to move the reducer.
•
Please remove all transportation fi xtures prior to startup of reducers.
4 Installation
4.1 Installation Notes
•
Check if the data on nameplate conforms to the operating requirement on site.
- Environment requirements for standard speed reducer:
- Ambient temperature:-10°C---40°C
- No oil, acid, smoke, noxious gas and radiation.
•
Check the mounting position, the rotation direction and the shaft direction are correct.
•
The base-plate must be fl at and secure, and the base-bolts must be screwed down and shockproof.
•
The shafts of prime mover, reducer and operation device must be coaxial after installation.
•
The diameter tolerance of input and output shaft is h6. The bolt hole (such as couplings, belt-pulley, sprocket wheel and so on) must
properly mate with the shaft, and this prevents the bearing from breakage due to being over-tightened and avoids poor power trans-
mission due to a loose connection.
Installation Tolerances(as follows)
Shaft End
Flange
Diameter tolerance
• ISO h6 (ISO h6 for solid shafts)
• ISO E8 (ISO E8 for input hollow shafts)
• ISO F8 (ISOE8 ISO E8 for output hollow shafts)
Register diameter shoulder tolerance
• ISO F7
• The input, output shafts, and fl anges receive an anti-corrosion coating before shipping. Please clean the output shafts
and fl ange surfaces thoroughly to ensure they are free from anti corrosion agents, contamination or grease using a
commercially available solvent. Do not let the solvent come into contact with the seals in order to prevent damage to the
material.
• Be sure that worm reducer had been fi lled with lubricant according to the following provisions before startup:
- Kuma series worm reducers are fi lled with lubricant in our factory. Please check if the oil level conform to the specifi ca-
tion prior to running for the model Kuma 110 to 150 frame. In case of any deviation for the oil level, please adjust to the
proper oil level. For lubricants and capacity, Please refer to the appendix” table 5 and table 8”.
• Drives such as sprocket wheel and gear must be fi tted closely to the bearing in order to reduce bending stress of a no off -
set load. Please refer to chart 1:
