How to install Rossi Planetary Reducer Gearmotor

❶Screw and tighten 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.

❷Flange installation

Before installation, please pay attention to cleaning and carefully fitting the surface. In the presence of external radial load or required torque M2 > = 0,7 ×. In the case of Mn2, it applies to locking adhesive.

❸Installation of gear reducer with a rotary output

For the gear reducer with rotary output (output design RSH), to ensure the correct operation and excellent power transmission between the gear reducer and the machine, the gear reducer needs a rigid connection structure to bear the radial load.

❹Shaft 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 freedom of movement and sufficient clearance in its coupling to allow slight vibration is used to prevent rotation – always evidence – will not cause dangerous overload on the gear reducer.

❺Installation of the 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, only lubricate the outer surface of the hollow shaft. Settle tighten the first 3 screws and position them at about 120 °. Install the gear reducer on the shaft end of the machine; Slowly insert the shaft to allow air to escape. Use a force measuring wrench to tighten it gradually and evenly in a continuous sequence (without crossing), about ¼ Turn several times until you can’t reach it again ¼ circle.  continue to apply the torque more than 1 or 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.

❻Adjustment of meshing clearance

To adjust the meshing clearance, it is recommended to put itself in the initial minimum clearance state, which can be obtained by making a maximum eccentricity on the gear reducer surface:

-If it is an internal gear, it faces the center of the rack; In the case of external 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 is within the range recommended by the frame manufacturer. It is recommended that a calibrated thickness be used to measure the gap. Only high-quality grease suitable for high load gear lubrication can be used for pinion and rack lubrication.
