| Thermal Rating & Hollow I/p Sizes |
| Planetary Gear Boxes, being very small in size & volume compared to other types of equivalent gear boxes, have a limitation on the heat dissipation capacity. Hence, in some cases, even though a particular size of gear box is mechanically / torque wise safe, it may so happen that thermally, it is not suitable for the Power being transmitted. Hence, it is necessary that while selecting the gear box, particularly for a continuous duty application, the thermal rating of the gear box should be checked for the suitability. The thermal rating of the gear box should be equal or more than the of the gear box should be checked for the suitability. The thermal rating of the gear box should be equal or more than the power to the gear box is more than the thermal rating (but well within the torque rating), it is necessary to provide a separate cooling arrangement for the gear box. It is not necessary to check the thermal rating of the gear box if it is sparingly used or used for in frequent duty. |
