The utility model provides a planetary gear case please combine fig. 1 and fig. 2, planetary gear case includes box 10 and locates first part 20 in the box 10, and first part 20 can be rotating member such as gear, pivot in the box. The planetary gearbox further includes a blocking member 30, and the blocking member 30 is disposed in the casing 10, and may be specifically mounted on the casing 10, or may be mounted on a component in the casing 10, which is not limited herein. The barrier 30 is used to block the debris 1 of the first part 20 from entering the adjacent chamber, and to avoid that when the first part 20 is damaged, the debris of the first part 20 is involved in the operation of the adjacent part, and the adjacent part is damaged. There is a first gap between the end of the blocking member 30 and the first part 20 or a second gap between the end of the blocking member 30 and the case 10 to allow the lubricating oil to pass therethrough. Since the blocking member 30 can be mounted on the case 10 or the first part 20, when the blocking member 30 is mounted on the case 10, a gap is required between the end of the blocking member 30 and the first part 20 for the lubricating oil to pass through. When the blocking member 30 is disposed on the first member 20, a gap is left between the end of the blocking member 30 and the case 10 for the lubricating oil to pass through, so that the operation of the lubricating system of the planetary gearbox is not affected.

In one embodiment, as shown in fig. 2, the blocking member 30 is disposed on the first member 20, one end of the blocking member 30 is connected to the first member 20, and the distal end of the blocking member 30 extends toward the housing 10. The stop member 30 may be secured to the first member 20 by a fastener or may be integrally formed with the first member 20. As shown in fig. 3, the blocking member 30 is integrally formed with the first part 20, so that not only the mounting step of additionally mounting the blocking member 30 can be omitted, the assembly time can be saved, but also the integrity of the gear box can be improved, the number of parts can be reduced, and in addition, the connection strength between the blocking member 30 and the first part 20 can be improved by integrally forming.
