Description
[
Technical field]
The utility model relates to small-sized and micromachine, particularly relates to the bracket component of small-sized or micromachine.
[
Background technology]
Bracket component small-sized or micromachine adopts the bearing compressing tablet that ball bearing is fixed on support, because the moment of small-sized or micromachine is less, therefore require the bearing compressing tablet to ball bearing, an appropriate precompression to be arranged, can make ball bearing can automatically adjust its sphere center position, can guarantee that again ball bearing itself can not rotate with rotating shaft when small-sized or micromachine operation.Referring to Figure 11 to Figure 13, the bracket component of the small-sized or micromachine of prior art, the bracket component of AC/DC universal series small-power series machine particularly, comprise support 10 ', ball bearing 20 and bearing compressing tablet 30 ', ball bearing 20 be placed in support 10 ' bearing chamber 11 ' in, again ball bearing 20 axial with the riveting method with bearing compressing tablet 30 ' be fixed on support 10 ' on, so just by bearing compressing tablet 30 ' strain with ball bearing 20 be pressed on support 10 ' bearing chamber 11 ' in, bearing compressing tablet 30 ' all the time ball bearing 20 has been applied a precompression; This type of fixing means is called the axial restraint method, and its shortcoming is as follows:
One, bearing compressing tablet 30 ' structure is more complicated, and material usage is many, and cost is high, and its force variation scope is also large, and elastic force is not easy to regulate;
Two, support 10 ' bearing chamber 11 ' be the tubular structure of both ends open, ball bearing 20 by double team support 10 ' bearing chamber 11 ' and bearing compressing tablet 30 ' between, cross-ventilation is bad, cooling effect is relatively poor, the ball bearing heat radiation is not good enough, causes ball bearing of short duration useful life;
Three, reliability is bad, and is fixing inconvenient: in 30 ' time of riveting bearing compressing tablet, if pressure is too small fixing not firm, can cause damage parts again if pressure is excessive;
Four, support 10 ' mould complicated; Bearing compressing tablet 30 ' processed complex.

Compare with prior art, the beneficial effect of the bracket component of the small-sized or micromachine of the utility model is:
1, simple in structure, material usage is less and cost is low: one section circular arc supporting part of holding ball bearing only is set on support, bearing chamber need not be set separately, can reduce the material usage of whole support, structure is also simple; And the bearing compressing tablet is to use the spring steel plate punch forming, only needs one section very narrow spring steel plate to get final product, and has also reduced the material usage of bearing compressing tablet, and structure is very simple; Due to all minimizings to some extent of material usage of support and bearing compressing tablet, therefore reduced the cost of whole bracket component;
2, convenient fixing, efficiency of assembling is high and easy dismounting: compare with the axial restraint method of prior art, this kind radially fixation do not need riveting to fix the bearing compressing tablet, and be less to " injury " of support, guaranteed simultaneously the precision of support yet; This Standard is simple and convenient, and is easy to dismounting, the efficient when having improved assembling;
3, the ball bearing heat radiation is good, be conducive to improve the useful life of motor: between the bearing chamber and bearing compressing tablet of support, cross-ventilation is bad by double team for the ball bearing in prior art axial restraint method, and cooling effect is relatively poor, the ball bearing heat radiation is not good enough, causes ball bearing of short duration useful life; And the utility model adopts the radially structure of fixation, and the ball bearing major part is exposed in air, and cooling effect is better, and the ball bearing temperature is low, and the ball bearing heat radiation is good, ball bearing long service life, the useful life that also is conducive to improve motor;
4, reliability is high: prior art axial restraint method, when riveting bearing compressing tablet, if pressure is too small fixing not firm, can cause damage parts again if pressure is excessive; And the utility model adopts the radially structure of fixation, the first hook part of bearing compressing tablet and the second hook part free end are separately caught on by the back-off structure of the back-off structure of the first column free end of support and the second column free end respectively, automatic fastening under the elastic force effect of bearing compressing tablet, strain only occurs in the bearing compressing tablet, but not plastic deformation, reliability is higher;
5, elastic force is easy to regulate: the angle that elastic force can be shaped by thickness and the bearing compressing tablet of bearing compressing tablet is regulated, and is easy to adjust.
The advantages such as in sum, small-sized or bracket component micromachine of the utility model has simple in structure, cheap, convenient fixing, efficiency of assembling is high, reliability is high, elastic force is easy to regulate and the bearing heat radiation is good.
