Structure is applied to speed reducer assembly.
Background technique
In domestic automobile drive axle, adjuster, diff. bearing uses band, and there are two the locking plates of bolt hole to lock, such
Structure also increases the material cost of locking plate and bolt firstly, increasing the weight of locking plate；Secondly, locking plate is fixed by bolts to
Differential bearing covers, and increases the machining cost of differential bearing lid；In addition, need to screw in two bolts when assembly,
Reduce assembly efficiency.To sum up, in existing drive axle, exist due to using bolt, the fixed differential bearing adjustment of lock plate structure
Nut leads to the weight for increasing bolt, locking plate, increases the material cost of bolt, locking plate, increases differential bearing lid
Machining cost, and assembly efficiency is led to problems such as to reduce.
Summary of the invention
The purpose of this utility model is that in view of the above shortcomings of the prior art, provides a kind of screw-type differential bearing
Lockable mechanism realizes drop weight, cost declining and promotes assembly efficiency.
The purpose of this utility model is achieved through the following technical solutions:
A kind of screw-type differential bearing lockable mechanism, it is characterised in that: by adjustment ring 3, spring washer 4 and stud pin 5
It constitutes；Two tapered roller bearings 2 of the differential mechanism are mounted in two semicircle orifices of reducing gearbox 1, two differential axles
The semicircle orifice and two tapered roller bearings 2 for holding lid 6 cooperate, and connect reducing gearbox 1 and differential bearing lid with four bolts 7
6；
The threaded hole that the adjustment ring 3 is constituted with reducing gearbox 1 and differential bearing lid 6 is fixed, and reducer gear reaches
The backlash of standard；The stud pin 5 passes through the screw hole of spring washer 4 and differential bearing lid 6, before stud pin 5
In the end-tooth groove of the journal diameter portion insertion adjustment ring 3 at end.
Further, the diameter of axle of the stud pin 5 is cylinder, is used for locking adjustment ring 3, and stud pin 5 passes through its screw thread
Diameter is spirally connected with differential bearing lid 6, and stud pin 5 is additionally provided with the turret head for connecting spanner.
It further, is the arch with boss at the top of the differential bearing lid 6, the center of boss is equipped with a screw thread
Hole is used for screw pitch stud pin 5, and differential bearing lid 6 is connect by its semicircle threaded hole with adjustment ring 3, and differential bearing lid 6 is also
