How to install the Rossi planetary reducer gear motor tighten and tighten the torque
Use screws and tightening torques according to the design and dimensions specified on the nameplate; At least level 10.9 is required, but in the case of heavy stress, alternating load and impact, level 12.9 is used (if m2<70% × Mn2 can use grade 8.8).Screws must be equipped with ISO 7089 washers (at least 300 HV). Carefully tighten the 12.9 screws. Over tightening will damage them.
flange installation
Please clean and carefully install the surface before installation. In the presence of external radial load or required torque m2>=0,7 ×. For Mn2, it is suitable for locking adhesive.
install the gear reducer with rotary output
For the gear reducer with rotating output (output design RSH), in order to ensure the correct operation and good power transmission between the gear reducer and the machine, the gear reducer needs a rigid connection structure to bear the radial load.
shaft installation layout
When installing the shaft, the gear reducer must be supported axially and radially by the shaft end of the driven machine, and only the reaction force with axial movement freedom and sufficient clearance in its coupling to allow slight vibration is used to prevent rotation - always evidence - will not cause dangerous overload to the gear reducer.
install hollow shaft with shrink disk
Carefully remove the surface of the hollow shaft and the shaft end of the driven machine to be installed. Install the shrink disc on the hollow shaft of the gear reducer. First, lubricate only the outer surface of the hollow shaft. Tighten the first three screws and place them at about 120 °. Install the gear reducer on the shaft end of the machine; Slowly insert the shaft so that air escapes. Use a force wrench to tighten gradually and evenly in a continuous sequence (without crossing), about ¼ Circle several times until you can't reach it again ¼ Circle. Continue to apply torque for more than 1 to 2 times and verify the bolt tightening torque. In heavy load cycles with frequent reversals, verify the bolt tightening torque again after several hours of operation.
adjustment of meshing clearance
In order to adjust the meshing clearance, it is recommended to put itself in the initial minimum clearance state, which can be obtained by manufacturing the maximum eccentricity on the surface of the gear reducer:
-If it is an internal gear, it faces the center of the rack; For the outer gear, 180 ° from the center of the rack. In this case, the meshing clearance shall not be less than 0,03 ÷ 0,04 x M. It is also recommended that the measured clearance be within the range recommended by the frame manufacturer. It is recommended to use a calibrated thickness to measure the gap. Only high-quality grease suitable for high load gear lubrication can be used for pinion and rack lubrication.
