Description
Technical field
The utility model belongs to a kind of body-building apparatus, more particularly to a kind of device for twisting waist.
Background technology
As shown in figure 1, the device for twisting waist of body-building apparatus, has waist torsional disk 1 and handle 16, waist torsional disk 1 can be installed rotationally
On base 8, in the fixed frame 15 of base 8, user stands (seat) on waist torsional disk 1, buttresses handle 16 and rotates waist torsional disk 1 and obtain
Taken exercise to swaying one's hips.
The waist torsional disk of structure often the selection of bearing or places irrational reason at present, after product installation, in a short time
I.e. can not normal use because of bearing damage.
Utility model content
The utility model provides a kind of novel waist twisting device tumbler, the purpose is to solve the shortcomings that prior art is present,
Device for twisting waist product is reached and the requirements such as rotation is smooth, does not fail are remained in standard service life.
Technical scheme is used by the utility model solves its technical problem：
A kind of novel waist twisting device tumbler, it is characterised in that：With the base and bearing holder (housing, cover) being connected as a single entity, bearing is arranged
Have through hole, be installed with annular damper in through hole, be installed with taper roll bearing in through hole above annular damper, in through hole
It is installed with deep groove ball bearing below annular damper, the rotating shaft that waist torsional disk stretches out down has the epimere and minor diameter of major diameter
Hypomere, hypomere sequentially pass through from top to bottom taper roll bearing, annular damper, deep groove ball bearing and with taper roll bearing, ring
Form drag Buddhist nun, deep groove ball bearing, which coordinate, to be arranged, and the lower surface of epimere is pressed in the upper surface of the inner ring of taper roll bearing.
It is of the present utility model to be beneficial in that：
When people stands in waist torsional disk apparent motion, because the lower surface of rotating shaft epimere is pressed in the inner ring of taper roll bearing
Load bearing support is played in upper surface by taper roll bearing, then the axial direction of waist torsional disk rotating shaft is fixed by deep groove ball bearing, makes
It only does circular-rotation, the swing without having other directions.The structure is born using the strong taper roll bearing of weight capacity
All loads, coordinate deep groove ball bearing that there is axial orientation effect again, can be with the solution waist torsional disk bearing of high degree along bad
Problem, and cost will not be increased so that device for twisting waist product can reach remained in standard service life rotate it is smooth,
Do not fail etc. and to require.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the utility model device for twisting waist outside drawing；
Fig. 2 is the utility model three-dimensional exploded view；
Fig. 3 is the utility model section view.
Embodiment
In order to illustrate more clearly of the technical solution of the utility model, the required accompanying drawing used in description will be made below
Simply introduce, it should be apparent that, drawings in the following description are only some embodiments of the utility model, for this area
For those of ordinary skill, on the premise of not paying creative work, other implement can also be obtained according to these accompanying drawings
Example.
As shown in Figure 2 and Figure 3, the utility model has base 8, and base 8 is in frame 15.
A bearing holder (housing, cover) 5 is installed with base 8 with M10 bolts and pad 4 to be integrally formed, bearing holder (housing, cover) 5 is provided with through hole 51, leads to
Annular damper 10 is installed with hole 51, dust-proof seal ring 11 is installed with above annular damper；In annular damper 10 in through hole 51
Top is installed with taper roll bearing 3, and the top of taper roll bearing 3 is installed with dust-proof seal ring 2；In annular damper in through hole 51
10 lower section is installed with deep groove ball bearing 6.
The rotating shaft 14 that waist torsional disk 1 stretches out down has the epimere 12 of major diameter and the hypomere 13 of minor diameter, and hypomere 13 is from upper
Sequentially passed through under taper roll bearing 3, annular damper 10, deep groove ball bearing 6 and with taper roll bearing 3, annular damper 10,
Deep groove ball bearing 6, which coordinates, to be arranged, and the bottom of hypomere 13 is external screw thread, and the round nut 7 set with external screw thread spiral shell locks stop washer 9
Tightly in the lower surface of deep groove ball bearing 6.
The lower surface of epimere 12 is pressed in the upper surface of the inner ring of taper roll bearing 3.
When people station is with 1 apparent motion of waist torsional disk, waist torsional disk 1 and rotating shaft 14 rotate, and the lower surface of epimere 12 is pressed in circular cone
The upper surface of the inner ring of roller bearing 3 by taper roll bearing 3 so that play load bearing support, then fixed by deep groove ball bearing 6
The axial direction of the rotating shaft 14 of waist torsional disk 1, makes it only do circular-rotation, the swing without having other directions.Damping 10 is used for
The inertia force of waist torsional disk is controlled, prevents waist torsional disk 1 from rapidly being rotated due to inertia.The structure uses the strong taper roller of weight capacity
Bearing 3 bears all loads, coordinates deep groove ball bearing 6 again with axial orientation effect, can be with the solution waist torsional disk of high degree
Bearing will not increase cost along bad the problem of.Protected all the time in standard service life so that device for twisting waist product can reach
Hold the requirements such as rotation is smooth, does not fail.
Each embodiment is described by the way of progressive in this specification, what each embodiment stressed be and other
The difference of embodiment, between each embodiment identical similar portion mutually referring to.To the upper of the disclosed embodiments
State bright, professional and technical personnel in the field is realized or using the utility model.A variety of modifications pair to these embodiments
It will be apparent for those skilled in the art, generic principles defined herein can not depart from this reality
