Appended drawing reference: 1. reducer shells, 2. splined input shafts, 3 bearings, 4. adjustment ring, 4,5. defining flange, 6. oil sealings,
7. adjustment ring locking plate, 8.O type circle
Specific embodiment
The technical characterstic of this programme to clearly illustrate below by a specific embodiment, and combines its attached drawing, to this
Scheme is illustrated.
The bearing limiting device of a kind of jackshaft speed reducer assembly as described in Figure 1, which is characterized in that including reducer shell
1, splined input shaft 2 is provided in the reducer shell 1, is arranged between the reducer shell 1 and splined input shaft 2
Have rolling bearing 3, which is characterized in that the outer end of bearing outer ring is equipped with an adjustment ring 4, the excircle of the adjustment ring 4 according to
It is secondary to be equipped with locking groove, O-ring mounting groove and thread segment, the locking groove and the adjustment ring for being fixed on 1 outer end of reducer shell
Locking plate 7 cooperates, and for preventing adjustment ring 4 from threadingly rotating, O-ring, the thread segment are equipped in the O-ring mounting groove
With being threadedly engaged for decelerating casing 1, the adjustment ring 4 can carry out preload adjusting to rolling bearing 3；The outer end of bearing inner race
Equipped with a defining flange 5, the defining flange 5 is connect with the spline of splined input shaft 2, and is locked via flange nut,
For carrying out axially position to rolling bearing 3；The oil to seal is provided between the adjustment ring 4 and defining flange 5
Envelope 6.
The inner periphery of the adjustment ring (4) is equipped with oil sealing and cooperates section, the oil sealing 6 oil sealing described by preparatory indentation
Cooperate section.
The two sides of the O-ring mounting groove are equipped with guiding step, and the height of the guiding step is 2.5mm.
Sealant is coated between the external thread section of the adjustment ring 4 and the threaded hole of decelerating casing 1.
Installation step is as follows:
1) on packing line, the 4 inner hole predetermined bits of indentation adjustment ring that Special press machine and pressure head are gentle in advance by oil sealing 6 are utilized
It sets, and the loading of O-ring 8 is coated in a small amount of lubricating grease O-ring mounting groove.
2) on general assembly line, splined input shaft 2 is attached on reducer shell 1, sealant then will be coated on thread segment
Adjustment ring 4 manually screw in the threaded hole of reducer shell 1, until revolve it is motionless until.
3) adjustment ring 4 is screwed to prescribed torque using definite value electric tightening machine, then adjustment ring 4 retracts defined circle
Number, after determining that splined input shaft 2 cannot shake, loads onto adjustment ring locking plate 7.
The positive effect of the present invention is:
The present invention utilizes O-ring and sealing dual-seal, to reach good sealing effect, reduces the whole bridge claim frequency；
Due to using sealant, adjustment ring can be retracted when assembling without influencing sealing effect, advised so adjustment ring retracts when assembly
Fixed circle number, it is ensured that will not even at the cost of one's life between splined input shaft and perforation axis, it can be to avoid splined input shaft early stage excessively mill
Damage.
