Dismantling and assembly of planetary mechanisms


Design of a planetary reducer

2 — the Forward planetary mechanism
3 — the Lock ring
4, 6, 8, 23 — Persistent bearings
5, 9 — Radial bearings
7 — the Connecting support
10 — the Solar gear wheel
11, 17, 22 — Washers
12, 20 — Sealing rings
13 — the Internal ring of the coupling of a free wheeling
14 — the Roller bearing

15 — the Spring
16 — Cylindrical rollers
18 — the Persistent washer
19 — the Internal disk of coupling К2
21 — the Blocking ring
24 — the Support
87 — the Leading shaft
99 — the Lubricant ring
167 — the Target shaft with the planetary mechanism
167a — Teflon rings


1. Disassemble a transmission (section 4).
2. Remove a lubricant ring (99).
3. Remove teflon rings (167a) from a target shaft (167).
4. Establish gear wheels with target shaft (167) on the assembly device.
5. By means of a screw-driver remove a lock ring (3).
6. Remove the forward planetary mechanism (2) and take the persistent bearing (3).
7. Remove the persistent bearing (4) and a leading shaft (37).
8. Remove the radial bearing (5) and the persistent bearing (6).
9. Remove a target shaft with the planetary mechanism (167).
10. Remove the radial bearing (9), the persistent bearing (8) and a solar gear wheel (10).
11. Remove the coupling (F2).


Assembly is carried out as it should be, the return to removal.
