Description
Technical field
The present invention relates to the axis of a kind of bicycle rim, particularly relate to the adjustable axis of a kind of bicycle rim.
Background technology
The axis of bicycle rim is mounted in the flower-drum in bicycle rim centre, and the position, both sides of axis has the Bearing screens for installing Bearing, and Bearing is i.e. bearing, is used for installing flower-drum.
But, owing to Bearing screens is fixing, assemble flower-drum, problems with will be produced: because of flower-drum when Bearing and axis, axis, all there is machining tolerance man-hour adding in Bearing screens, the flower-drum width machining tolerance variation of wheel rim, Bearing is caused to be likely to occur Bearing and axis after having assembled, Bearing and flower-drum excesssive gap or too small, such as flower-drum machining tolerance walks the upper limit, flower-drum width will become big, just axis card bit width machining tolerance is gone down in limited time, Bearing is contained in width in axis screens and just diminishes, and flower-drum width becomes big, therefore just there is gap between Bearing and flower-drum；If instead flower-drum width tolerance diminishes, axis screens width tolerance becomes big, then will be stuck on flower-drum after Bearing is contained on axis, cause assemble between axis, Bearing and flower-drum three bad.Excesssive gap can cause axis and wheel rim to occur rocking, and gap is too small or very close to each other, then Bearing can be stuck, and causes wheel rim to rotate and has some setbacks.
Summary of the invention
It is an object of the invention to provide a kind of simple in construction, be easily achieved, can improve wheel rim axis assemble precision, ensure that wheel rim rotates the adjustable axis of bicycle rim smoothly.
The purpose of the present invention is realized by following measures: the adjustable axis of a kind of bicycle rim, including axis body, the position, both sides of described axis body is provided with a pair for the Bearing screens installing Bearing, it is characterised in that: Bearing screens is implemented regulation so that the spacing of the two is adjustable by governor motion by this.
Spacing between two Bearing screens of the present invention is adjustable, after flower-drum, axis and Bearing are assembled, flower-drum can be arranged on the suitable position of Bearing by the spacing between two Bearing screens of regulation, improve wheel rim axis and assemble precision, axis and wheel rim not only can be avoided to occur rocking, and it is smooth and easy to be able to ensure that wheel rim rotates.
As one embodiment of the present invention, described axis body is mainly formed by left section of axis body and right section of axis body docking, described Bearing screens lays respectively on left section of axis body and right section of axis body, described left section of axis body and right section of axis body are respectively provided with linkage section, described linkage section is docked by described governor motion, and the entire length making axis body is adjustable while, the spacing between two Bearing screens is adjustable.
A kind of preferred implementation as the present invention, the linkage section of one of described left section of axis body and right section of axis body is tubular and is provided with female thread, another linkage section is cylindricality and is provided with external screw thread, governor motion described in the suitable composition of described internal and external threads, being matched by the linkage section of left section of axis body and right section of axis body is screwed in or to screw out the spacing that realizes between two Bearing screens adjustable.
As another embodiment of the invention, one of them Bearing screens is the adjusting nut that thread bush is connected on this side of axis body, and described adjusting nut moves the governor motion described in constituting so that the spacing of two Bearing screens is adjustable on axis body.
In order to avoid adjusting nut after regulating position freely rotatable and be subjected to displacement, as a modification of the present invention, on described axis body, thread bush is connected to stop nut, described stop nut is positioned at the inner side of described adjusting nut, the thread segment of the axis body at described stop nut place is major thread section, the thread segment of the axis body at described adjusting nut place is minor thread section, the major diameter of thread of described major thread section is more than the major diameter of thread of described minor thread section, described stop nut in major thread section towards outer side shifting to press described adjusting nut and adjusting nut is locked.
Compared with prior art, the present invention has a following significantly effect:
Spacing between two Bearing screens of the present invention is adjustable, after flower-drum, axis and Bearing are assembled, flower-drum can be arranged on the suitable position of Bearing by the spacing between two Bearing screens of regulation, improve wheel rim axis and assemble precision, axis and wheel rim not only can be avoided to occur rocking, and it is smooth and easy to be able to ensure that wheel rim rotates.It addition, present configuration is simple, be easily achieved, it is widely portable to the axis of various wheel rim.
