Gear, shaft and bearing combination

The pinion gear is integrated with the shaft and is called the gear shaft. This structure is used when the diameter of the gear is not related to the diameter of the shaft. If the diameter of the shaft is d, the diameter of the tooth root circle is df, then df- When d ≤ 6 to 7mn, this structure should be adopted. When df-d>6 to 7mn, the gear and shaft are separated into two parts, such as a low speed shaft and a large gear. At this time, the gear is fixedly coupled with the shaft in the circumferential direction, and the shaft is fixed axially with the shaft shoulder, the sleeve and the bearing cover. Both shafts are deep groove ball bearings. This combination is used to withstand radial loads and not


Large axial load condition. When the axial load is large, angular contact ball bearings, tapered roller bearings, or a combination of deep groove ball bearings and thrust bearings should be used. The bearing is lubricated by thin oil that splashes when the gear rotates. The oil in the oil pool in the box seat is splashed and splashed by the rotating gear onto the inner wall of the box lid. After flowing along the inner wall to the bevel of the box box, it flows into the bearing through the oil guide groove. When the circumferential speed of the oil-impregnated gear υ ≤ 2m/s, the bearing should be lubricated with grease. To avoid the grease that may splash off the thin oil, you can use the oil ring to separate it. In order to prevent the loss of lubricating oil and the outside dust entering the box, sealing elements are installed between the bearing end cover and the outreach shaft.
