Description
Technical field
This utility model is related to a kind of locking device of adjuster, diff. bearing, drive axle and wheel-type working machine tool.
Background technology
The assembly of the drive mechanism after the drive axle of wheel-type working machine tool is commonly referred to as power transmission shaft, before driving wheel,
Mainly include the mechanisms such as main reducing gear, differential mechanism, semiaxis, hub reduction gear and axle housing.Wherein, main reducing gear is for by variator
The power of output slows down after increasing torsion again, imparts power to differential mechanism.Differential mechanism is used to realize the automatic of both sides vehicle wheel rotational speed
Adjust so that vehicle is in turning driving, it is allowed to which left and right wheelses are rotated with different rotating speeds.
Fig. 1 shows the typical structure of main reducing gear and differential assembly in prior art, as illustrated, main reducing gear and
Differential assembly includes：Bevel housing 11 ', differential bearing lid 12 ', bolt of bearing cap 13 ', main tooth locking nut 41 ',
Main pinion holds 42 ', driving gear 43 ', differential bearing 51 ', differential assembly 52 ', adjuster, diff. bearing 2 ', locking
The part such as piece 14 ', bolt 15 ', driven gear 16 ', driven fixing bolt 17 ' constitutes.
In above-mentioned part, the bevel housing 11 ' linked together by bolt of bearing cap 13 ' and 12 ' group of bearing cap
Into main reducing gear housing assy 1 ', frame is played a part of in main reducing gear housing assy 1 ', can support driving gear 43 ', differential simultaneously
The part such as device assembly 52 ' and driven gear 16 '.Main pinion holds 42 ' and plays supporting role to driving gear 43 ', it is possible to pass through
Setting up pad and holding 42 ' to main pinion carries out pretension.It is after the position of driving gear 43 ' and driven gear 16 ' is adjusted, tight respectively
Gu main tooth locking nut 41 ', driven fixing bolt 17 ', can strengthen the rigidity of driving gear 43 ' and driven gear 16 '.
Half bore is formed with bevel housing 11 ', half bore on differential bearing lid 12 ', is formed with, each half bore adds respectively
After work has female thread, differential bearing lid 12 ' to be attached on bevel housing 11 ' by bolt of bearing cap 13 ', both half
Close and form a complete screwed hole with internal thread segment in hole.Differential bearing 51 ' is non-in the screwed hole
Screw thread fragment position, supporting differential assembly 52 ' and driven gear 16 '.The interior spiral shell of adjuster, diff. bearing 2 ' and screwed hole
Stricture of vagina section coordinates, and by turning adjuster, diff. bearing 2 ', pretension can be carried out to differential bearing 51 ', and then by poor
Fast device assembly 52 ' applies radial force to driven gear 16 ', to adjust the back lash of driving gear 43 ' and driven gear 16 '.
With reference to Fig. 2 is referred to, the rotation of adjuster, diff. bearing 2 ' is carried out to which by lock banking stop 14 ' and bolt 15 '
Locking.Specifically, it is circumferentially arranged on the periphery of adjuster, diff. bearing 2 ' to have multiple anti-rotating holes 20 ', lock banking stop 14 '
First end be attached on differential bearing lid 12 ' by bolt 15 ', the second end of lock banking stop 14 ' extend into anti-rotating hole 20 '
It is interior, moved back with the pine for preventing adjuster, diff. bearing 2 '.This kind of anti-loose structure, as lock banking stop 14 ' is adjusted with differential bearing
The anti-rotating hole of whole nut 2 ' can not be fitted completely, and gap is larger, it is impossible to play reliable locking effect, differential mechanism during use
Bearing adjusting nut 2 ' easily loosens, and causes 11 ' gap of differential bearing to become big so that driving gear 43 ' and driven gear 16 '
Engaged transmission can not carry out by normal path of action, produce the premature breakdown of grating of gears, abnormal sound and part.
