Abstract
The invention refers to transmission chain technology, it provides a kind of U shape chain board which has two ends assorted with the inner holes of two rotors, the end of chain board has arc plane which can assort with rotor, the other end of the chain board has brake mechanism which can stop the rotation. In this invention, the position of rotor and chain board can keep fixed; the other end and rotor is free.
Description
Affiliated technical field:
The present invention relates to a kind of Transmitted chains technology, mainly propose a kind of carrier bar.
Background technique:
In the stepless change transmission of the circle kind of drive of switching political loyalty, its Transmitted chains is the key of energy transmitted power and torque capacity.In the rubbing contact motion of Transmitted chains and V-arrangement wheel, must guarantee the correct location of friction driving element (being roller), effectively transmitted power and moment of torsion.
Summary of the invention:
The purpose of this invention is to provide a kind of carrier bar, use is in the stepless change transmission, can make the friction driving element (being roller) of Transmitted chains, keep correct positioning at the volley, can transmit enough big power and moment of torsion with the assurance Transmitted chains, and improve its transmission efficiency, reliability and working life.
Technological scheme of the present invention is: the carrier bar external form takes the shape of the letter U, have two ends that cooperate with the endoporus of two rollers respectively, an end of its intermediate plate has the arc surface that is rotatably assorted with the roller endoporus, the another one end of carrier bar have limit that itself and roller endoporus rotate mutually only revolve structure, all have the attachment hole that is connected with roller by bearing pin on two ends.
Only revolving structure is the projection that has on the end main body.
Only revolving structure is the depression that has on the end main body.
Only revolve structure and can be two planes that are positioned at arc surface top and protrude in arc surface, limit relatively rotating between itself and the roller.
Only revolve structure and can be the projection that is positioned on the arc surface, cooperate, limit relatively rotating of the two with the depression of roller endoporus.
Only revolve structure and can be the depression that is positioned on the arc surface, cooperate, limit relatively rotating of the two with the projection of roller endoporus.
The carrier bar that the present invention proposes because an end is provided with and only revolves structure, can make the roller and the carrier bar relative position that cooperate with this end be maintained fixed; The other end and roller are free movement state.Like this, both keep the fixed-site of roller and carrier bar, satisfied requirement movable between adjacent rollers again.
Description of drawings:
Accompanying drawing 1 is the structural representation of the embodiment of the invention 1.
Accompanying drawing 2 is structural representations of the embodiment of the invention 2.
Accompanying drawing 3 is structural representations of the embodiment of the invention 3.
Among the figure: 1-carrier bar, A, B-carrier bar end, 1a, 1b-convex plane, 1c-projection, 1d-depression.
Embodiment:
In conjunction with the accompanying drawings embodiment is further specified:
In the embodiment in figure 1: carrier bar 1 external form takes the shape of the letter U, have two end A, B cooperating with the endoporus of two rollers respectively, the end B of its intermediate plate has the arc surface that is rotatably assorted with the roller endoporus, the end A of carrier bar have limit that itself and roller endoporus rotate mutually only revolve structure.Certainly, the structure of end A and end B can be exchanged.
Two end A, B respectively have an attachment hole, are used for the plug-in mounting bearing pin.Carrier bar is connected with roller by bearing pin.
The end B of carrier bar is the arc surface structure, and during use, itself and roller endoporus are and relatively rotate mated condition.The end A main body of carrier bar is an arc surface, and have limit that itself and roller endoporus rotate mutually only revolve structure.Only revolve structure and can be two convex plane 1a, 1b that are positioned at arc surface top and protrude in arc surface.Carrier bar can be metallic material, also can be other material and makes.
As shown in Figure 2: its agent structure is identical with embodiment 1; Only revolving structure is the protruding 1c that is positioned on the arc surface, during use, cooperates with the depression of roller endoporus, limits relatively rotating of the two.
As shown in Figure 3: its agent structure is identical with embodiment 1; Only revolving structure is the depression 1d that is positioned on the arc surface, during use, cooperates with the projection of roller endoporus, limits relatively rotating of the two.
During use, two ends of one group of a plurality of carrier bar are inserted in the groove of adjacent two sleeve-barrel roollrs, and bearing pin is connected as a single entity carrier bar and sleeve-barrel roollr by two attachment holes that the end had of carrier bar; A plurality of sleeve-barrel roollrs are interconnected to constitute the endless drive chain by carrier bar and bearing pin.Because carrier bar one end is provided with and only revolves structure, and the roller and the carrier bar relative position that cooperate with this end are maintained fixed; The other end and roller are free movement state.Like this, both keep the fixed-site of roller and carrier bar, satisfied requirement movable between adjacent rollers again.The Transmitted chains of this kind carrier bar is housed, use is in the Transmitted chains of stepless change transmission, end face with sleeve-barrel roollr cooperates with the inclined-plane of V-arrangement wheel, rely on the friction carry-over moment of the two, can make enough big power of infinitely variable speed transmission transmission and moment of torsion, and improve its transmission efficiency, reliability and working life.
