Description
Technical field
The utility model belongs to automobile drive axle retarder technical field, and in particular to a kind of control differential bearing preload
The adjustment structure of power.
Background technique
Differential mechanism in automobile driving axle main gear box plays critically important effect in running car, and differential bearing
The rotation of differential mechanism is support, the position of bearing also affects the engagement of driving and driven bevel gear, design requirement differential axle simultaneously
Holding needs certain pretightning force, and the support stiffness and running accuracy of bearing can be improved in suitable pretightning force.Currently, generally adopting
The difference of front and back differential mechanism bearing cap diagonal distance is pre-tightened with measurement to judge whether pretightning force meets the requirements.It is now most of
In factory, the adjustment of pretightning force is all the experience by master worker, and there are the risks that pretightning force does not meet design requirement, and is filled
It is time-consuming and laborious with needing to adjust repeatedly.
Utility model content
The utility model aiming at the above shortcomings existing in the prior art, provides a kind of control differential bearing pretightning force
Adjustment structure, within the scope of reasonable pretightning force, relatively large pretightning force is advantageous the operating of bearing, and limits axis
Hold pretightning force increase is exactly the space of installation retarder in axle housing.
The utility model is achieved through the following technical solutions:
A kind of adjustment knot controlling differential bearing pretightning force, including adjustment sleeve 1, the adjustment sleeve 1 are a cylinder
Body sleeve, upper and lower end face diameter of a circle is different, and lower end surface circular diameter is greater than upper surface circular diameter；In being provided on the lower end surface
Seam allowance, matches with the male half coupling of the flange face of reducer shell, 4 tapped through holes is additionally provided on lower end surface, for connecting
Reducer shell；Respectively there are an oblong hole in 1 two sides of sleeve, for adjusting adjustment ring 6.
Further, the upper surface diameter of a circle is 1mm smaller than the diameter of 9 center hole of axle housing.
Further, the sleeve 1 connect by adjusting sleeve fixing bolt 7 with reducer shell.
Compared with prior art, as follows the advantages of the utility model:
A kind of adjustment structure for controlling differential bearing pretightning force of the utility model, realizes differential axle by adjusting sleeve
Pretightning force maximization is held, the quantitative maximum pretightning force for controlling bearing does not need assembler and by virtue of experience estimates, and covers
Barrel structure is simple, and installing and dismounting is time saving and energy saving, and the slotted hole on sleeve is that sufficient space has been reserved in the adjusting of adjustment ring, convenient fast
Prompt improves regulated efficiency, has very high practicability.

Specific embodiment
The utility model is described further with reference to the accompanying drawing.
Embodiment 1
A kind of adjustment knot controlling differential bearing pretightning force, including adjustment sleeve 1, the adjustment sleeve 1 are a cylinder
Body sleeve, upper and lower end face circle φ A, the diameter of φ B are different；
It is provided with inner stopper on the lower end surface, is matched with the male half coupling of the flange face of reducer shell, on lower end surface
4 tapped through holes are additionally provided with, for connecting reducer shell；
Respectively there are an oblong hole in 1 two sides of sleeve, for adjusting adjustment ring 6.
Further, the upper surface diameter of a circle is 1mm smaller than the diameter of 9 center hole of axle housing.
Further, the sleeve 1 connect by adjusting sleeve fixing bolt 7 with reducer shell.
φ A=422mm, φ B=424mm, 9 Circularhole diameter of axle housing are φ 423mm in the present embodiment.
A kind of application method for the adjustment structure for controlling differential bearing pretightning force of the utility model, specific as follows:
Differential assembly 3 is packed into differential casing 2, differential bearing lid 4 is covered, tightens differential bearing lid and fix
Bolt 5 screws in adjustment ring 6, speed reducer assembly is horizontally arranged, and puts on adjustment sleeve 1, makes the inner stopper and the deceleration that adjust sleeve
The male half coupling of device shell matches, and the face 1-1 for adjusting structure is in contact with the face 2-1 of speed reducer assembly, then installs 4 adjustment sleeves
Fixing bolt 7, and hex nut 8 is tightened, continue to adjust adjustment ring 6, adjustment ring 6 screw-in depth in two sides is consistent, and works as adjustment
When adjustment ring, differential bearing lid is expanded outwardly, and increases differential bearing pretightning force, when pretightning force reaches permission maximum value, until
Differential bearing lid 4 encounters adjustment 1 inner wall of sleeve, and adjustment stops, and removes 4 hex nuts 8 and adjustment sleeve fixing bolt 7,
Adjustment sleeve 1 is taken down, the adjustment of differential bearing pretightning force is completed.
