Description
Technical field
The utility model is related to a kind of bearing pre-tightening structures.
Background technology
In gear spindle drive system, bearing is improved by applying certain pretightning force to it to eliminate bearing clearance
Rigidity, the positioning accuracy of bearing and running accuracy, the vibration and noise for lowering bearing.Pretightning force can cause bearing working when excessive
Temperature liter is excessively high, be easy to cause the initial failure of bearing；Pretightning force is too small, and when running at high speed, bearing is unable to even running again, needs
The variable adjustment structure of pretightning force.At present in the variable adjustment structure of pretightning force, usually using butterfly spring as strength buffering and
Damping spring, butterfly spring have many advantages, such as that assembly space is small, and rigid scope is big, but that there are intensity is low, uses the longevity for butterfly spring
It orders short, the problem of stability and impact resistance force difference, influences use quality and the service life of product.
Invention content
The purpose of this utility model is to provide a kind of bearing pre-tightening structure, is ensureing that the assembly space of original structure is small, rigid
Other than the big feature of range, also has the characteristics that intensity is high, stability is good, impact resistance is strong, ensure quality and the use of product
Service life.
The technical solution of the utility model：Bearing pre-tightening structure includes shell, gear shaft, first bearing, second bearing, tune
Whole washer, waveform spring, gear shaft are mounted on by first bearing, second bearing on shell, and the first bearing and the
Two bearings are located at the both sides of gear, and adjusting washer, waveform spring, the tune are provided between shell and first bearing outer shroud
It is in impaction state that the thickness of whole washer, which can ensure waveform spring after mounting,.
The utility model ensures that waveform spring has the axial stroke of particular requirement by matching adjusting washer, ensures bullet
Spring compresses completely, is in Pre strained state always when realizing bearing working, has achieved the purpose that bearing axial pretightening.Outside waveform spring
Shape and disk spring adjoining dimensions, have the characteristics that assembly space is small, rigid scope is big, meanwhile, waveform spring is relative to butterfly
For spring, intensity is high, and buffering damping capaicty is stronger, keeps stability more preferable, impact resistance is stronger, advantageously ensures that the matter of product
Amount and service life.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the partial enlarged view of Fig. 1；
Fig. 3 is waveform spring schematic diagram.
Specific implementation mode
As shown, bearing pre-tightening structure include shell 1, gear shaft 3, first bearing 2, second bearing 4, adjusting washer 5,
Waveform spring 6, gear shaft 3 is mounted on by first bearing 2, second bearing 4 on shell 1, and the first bearing 2 and second
Bearing 4 is located at the both sides of gear, and adjusting washer 5, waveform spring 6 are provided between 2 outer shroud of shell 1 and first bearing, described
Adjusting washer 5 thickness can ensure waveform spring 6 after mounting be in impaction state.
