Foregoing paired thrust ball bearing pre-tightening apparatus, the elastic component are annular angled section spring 9.
Thrust ball bearing pre-tightening apparatus in pairs proposed by the present invention uses annular angled section spring, its contact area compared with
Greatly, elastic force is uniform.Spring stress is set to produce certain precommpression by tightening nut to some extent when mounted, by spring
Automatic recovery deformation characteristic compensate automatically rolling element and raceway abrasion caused by gap value.
Described above is only the general introduction of technical solution of the present invention, in order to better understand the technological means of the present invention, and
It can be practiced according to the content of specification, and to allow the above and other objects, features and advantages of the present invention can be brighter
It is aobvious understandable, below especially exemplified by preferred embodiment, and coordinate accompanying drawing, describe in detail as follows.

Embodiment
Further to illustrate the present invention to reach the technological means and effect that predetermined goal of the invention is taken, below in conjunction with
Accompanying drawing and preferred embodiment, to according to thrust ball bearing pre-tightening apparatus its embodiment in pairs proposed by the present invention, structure,
Feature and its effect, describe in detail as after.
Referring to Fig. 1, paired thrust ball bearing pre-tightening apparatus, includes nut 1,9, two folders of angled section spring of annular
Plate is held, two thrust ball bearings 3 are back-to-back to be sleeved on power transmission shaft 10, and the outer ring of two thrust ball bearings 3 is supported on bearing
On seat 4；The inner ring of two thrust ball bearings 3 is fixed by nut 1, the first axle sleeve 2, the first axle sleeve 2 be clamped in nut 1 with it is close
Between the inner ring of the thrust ball bearing 3 of the end of power transmission shaft 10, nut 1 is arranged on the ground end of power transmission shaft 10 and compresses the first axle sleeve 2,
It can be moved axially by rotation；The outer ring of two thrust ball bearings 3 is fixed by bearing (ball) cover 6, the second axle sleeve 5, the second axle
Set 5 is clamped between two thrust ball bearings 3, and bearing (ball) cover 6 is arranged on bearing block 4.
(position that i.e. external diameter changes) is provided with the first grip block 7 of annular at the shaft shoulder of the power transmission shaft 10, close to biography
The inner ring of thrust ball bearing 3 at the shaft shoulder of moving axis 10 is provided with the second grip block 8 of annular, the first grip block 7, the second grip block 8
Between be folded with annular angled section spring 9, the stress of annular angled section spring 9 produces certain precommpression during tightening nut 1.
As the further improvement of the present invention, the both sides of the annular bottom of angled section spring 9 abut a thrust respectively
Ring plate 11, two thrust ring plates 11 are between two grip blocks and are set on power transmission shaft 10.The work of thrust ring plate 11
With being：Ensure that spring force is respectively acting on the shaft shoulder and bearing inner race when spring stress compresses, realize optimal pretension effect
Fruit.
Using annular angled section spring 9 as elastic component in the present embodiment, but the present invention does not limit the species of elastic component.
A kind of operation principle of thrust ball bearing pre-tightening apparatus in pairs of the present invention is：
After foregoing assembled relation installation, by tightening nut 1, the annular stress of angled section spring 9 produces one
Fixed precommpression, spring force push away the inner ring of thrust ball bearing 3 to the left, produce two inner rings of thrust ball bearing 3 adjacent to each other
Pretightning force, make two bearing pre-tighteneds, while raceway in the outer raceway of the inner ring for eliminating two thrust ball bearings 3, rolling element and outer ring
Between gap.It is now annular because abrasion can produce gap between raceway and rolling element after bearing uses a period of time
The meeting recovered part deformation of angled section spring 9 is compensated due to gap caused by abrasion automatically.
The above described is only a preferred embodiment of the present invention, any person skilled in the art is not departing from
