Abstract
The utility model discloses a self-positioning coaxiality connecting pair which comprises a drum-shaped sleeve with the inner circle in a drum shape, and a shaft seat with an outer circle in a drum shape and matched with the drum-shaped sleeve. The drum-shaped sleeve is matched with the shaft seat, balls are further arranged, and therefore the connecting pair can swing automatically in the peripheral direction to adjust coaxiality, reaction flexibility is guaranteed, in the mounting process, friction pairs can be adjusted automatically, partial friction can not be caused, unbalance force can not be caused, the service lives of friction pair components can be prolonged, and driving safety of a vehicle can be guaranteed at the same time. The diameter of an inner hole, matched with a bearing seat, of the shaft seat increases gradually from the middle to two ends, the inner hole is matched with the bearing seat in a line contact mode, and therefore if assembly deviation happens, a wheel shaft can swing in a small range relative to the shaft seat, and the centering purpose is achieved.
Description
Technical field
The utility model relates to a kind of mechanical structure of automatic adjustment coaxality.
Background technique
In the mechanical connection cooperating structure, more situation requires cooperation coaxality both, and particularly the problems such as eccentric wear, can appear in some structure in relative rotation if coaxality can not guarantee, affects the normal operation of device.Particularly, if can not guarantee when the axis hole coaxality of rotating shaft, the bearing of rotatable parts is rubbed partially, improve the cost of overhaul of sports equipment.Even can produce additional moment, just can not guarantee that moment accurately transmits, affect machine regular event and operation.
Therefore, need a kind of linkage structure, during installation if there is artificial deflection, can automatically adjust coaxality by mechanical force during use, avoid partially rubbing, extend the working life of friction pair parts, the equipment of assurance has smoothness preferably, and conveniently adjusts coaxality in installation process.
Summary of the invention
In view of this, the purpose of this utility model is to provide a kind of self-align coaxality auxiliary connection, during installation if there is artificial deflection, can automatically adjust coaxality by mechanical force during use, avoid partially rubbing, extend the working life of friction pair parts, the equipment of assurance has smoothness preferably, and conveniently adjusts coaxality in installation process.
Self-align coaxality auxiliary connection of the present utility model, comprise inner circle be the cydariform cover of cydariform and cylindrical be cydariform and with cydariform overlap coordinate axle bed.
Preferably, the axle bed cylindrical is provided with the ball telescoping groove, and the ball telescoping groove is embedded with rotatable ball, and described cydariform cover is coated at the axle bed cylindrical and rolls by ball with it and coordinate.
Preferably, described ball telescoping groove and ball corresponding setting and along axle bed cylindrical circumferencial direction with axially form array-type and distribute one by one.
Preferably, the interior diameter of a circle of described axle bed is increased gradually to two ends by the centre and is arc-shaped transition to two ends by the centre.
The beneficial effects of the utility model are: self-align coaxality auxiliary connection of the present utility model, adopt the cydariform cover to coordinate with axle bed, and be provided with ball, can adjust coaxality at the circumferencial direction automatic swing, and guarantee the flexibility of reaction, in installation process, each friction pair can be mediated automatically, can not cause partially and rub, avoid causing unbalanced force, guarantee the driving safety of vehicle when extending working life of friction pair parts; The diameter of the endoporus that axle bed coordinates with bearing support is increased to two ends gradually by the centre, and the mode that contacts with line coordinates, and therefore if there is assembling deviation, wheel shaft can swing by a small margin with respect to axle bed, reaches the centering purpose.
Description of drawings
Below in conjunction with drawings and Examples, the utility model is further described.
Fig. 1 is the utility model structural representation.
Embodiment
Accompanying drawing is the utility model structural representation, as shown in the figure: the self-align coaxality auxiliary connection of the present embodiment, comprise inner circle be the cydariform cover 1 of cydariform and cylindrical be cydariform and coordinate with the cydariform cover axle bed 3.
Preferably, axle bed 3 cylindricals are provided with the ball telescoping groove, and the ball telescoping groove is embedded with rotatable ball 2, and described cydariform cover 1 is coated at axle bed 3 cylindricals and coordinates by ball 2 rollings with it.
Preferably, described ball telescoping groove 4 and ball 2 corresponding setting and along axle bed cylindrical circumferencial direction with axially form array-type and distribute one by one; Has stability preferably.
Preferably, the interior diameter of a circle of described axle bed 3 is increased gradually to two ends by the centre and is arc-shaped transition to two ends by the centre.
For the utility model can clearly be described; above embodiment makes specifically clearly explanation to the utility model; can not limit protection domain of the present utility model; therefore; those of ordinary skill in the art all drops in the middle of claim scope of the present utility model the apparent modification that the utility model carries out.
