Description
Technical field
Hit the present invention relates to a kind of ring for conical ring formula buncher and stop protection structure.
Background technology
Conical ring formula buncher (hereinafter referred to as KRG) is that a kind of bored using input clamps transmission ring with output cone, by rubbing
Wipe the buncher of transmission.KRG design concept is to avoid hydraulic pump in any manner, only with simple and durable machine
Tool part is controlled by motor.Compared with traditional infinitely variable transmission (CVT), KRG this design concept is manufacturing it
Possess big advantage in terms of cost and efficiency.
As shown in figure 1, in KRG transmissions, input 2 ＇ of cone and 3 ＇ of output cone clamp the ＇ of transmission ring 1, the ＇ of transmission ring 1 interior appearance
Face produces frictional force with input 2 ＇ of cone and 3 ＇ of output cone respectively, and power is delivered to 3 ＇ of output cone from input 2 ＇ of cone through the ＇ of transmission ring 1.
As shown in Fig. 2 a normal surface vertical with axis of cone line P ＇ is made with the contact point of poppet surface by the ＇ of transmission ring 1.
In KRG transmission process, if the ＇ of transmission ring 1 transverse plane is parallel with above-mentioned normal surface, the ＇ of transmission ring 1 axis of cone line P ＇ to
Position will keep constant, and the radius of turn of contact point and 3 ＇ of input 2 ＇ of cone and output cone is constant, and input 2 ＇ of cone protect with 3 ＇ of output cone
Hold specific gearratio.The positions of the ＇ of transmission ring 1 now are back positive position.
As shown in Figure 3, Figure 4, in transmission process, if the ＇ of transmission ring 1 transverse plane and above-mentioned normal surface are not parallel, i.e.,
There is deflection, then the ＇ of transmission ring 1 can move along transmission element of a cone direction, the rotation half of contact point and 3 ＇ of input 2 ＇ of cone and output cone
Footpath changes, and then changes input 2 ＇ of cone and 3 ＇ of output cone gearratio.KRG can be real by changing the ＇ of transmission ring 1 axial location
The change of existing gearratio.
Research shows, the inflow side of transmission ring speed at contact point, the deviation and transmission ring of plane where the ＇ of transmission ring 1
1 ＇ moving direction is consistent.When under the rolling condition shown in Fig. 1, if velocity of rotation directions of the ＇ of transmission ring 1 at contact point be to
Interior, if the ＇ of transmission ring 1 front portions have left avertence angle, the ＇ of transmission ring 1 is moved to the left, as shown in Figure 3；Conversely, then move right,
As shown in Figure 4.
, can be with the axle of two cones when the ＇ of transmission ring 1 axially moves to the extreme position at both ends in traditional KRG conical rings transmission
Other parts of shoulder or speed changer hit, so as to cause the damage of transmission ring or associated components.
The content of the invention
In order to overcome existing KRG transmission rings the limit hit stop in there is the problem of damage parts, the invention provides one kind
Ring for conical ring formula buncher, which is hit, stops protection structure.
The technical solution adopted by the present invention is：
Ring for conical ring formula buncher, which is hit, stops protection structure, including the first transmission cone, transmission ring, the first transmission cone
Surface contacted with a surface of transmission ring, described first transmission cone small end is provided with the shaft shoulder relative with poppet surface, institute
The shaft shoulder stated has the shape of revolving body；Described transmission ring, the shaft shoulder, poppet surface have following geometry matching relationship：Work as transmission
When ring contacts the shaft shoulder, there is first make contact between transmission ring and the shaft shoulder, while have the second contact point between transmission ring and poppet surface,
The distance of first make contact to axis of cone line is the first contact radius, and the distance of the second contact point to axis of cone line is the second contact half
Footpath, the first described contact radius are less than the second contact radius.
Further, on the axle section made by described axis of cone line, the bus of the described shaft shoulder is in first make contact
On tangent line form obtuse angle between transmission ring side and axis of cone line.Obtuse angle be advantageous between transmission ring and the shaft shoulder formed clearly and
Stable first make contact.
Further, the bus of the described shaft shoulder is straight line or curve.
Further, another surface of transmission ring contacts with the 3rd transmission parts, and transmission ring is in the first transmission cone and the
Passing power between three transmission parts.
Further, the 3rd described transmission parts are the second transmission cones, and the described first transmission cone is input cone, is driven
For ring set on the first transmission cone, the second transmission cone is output cone；The cone nut line of the cone nut line of first transmission cone and the second transmission cone
It is parallel.
The first described transmission cone is identical with the taper of the second transmission cone, the axis of cone line and second of the first described transmission cone
The cone diameter parallel of cone is driven, big end is oppositely arranged with small end.
Or the 3rd described transmission parts are the second transmission cones, the described second transmission cone is input cone, is driven ring set
On the second transmission cone, the first transmission cone is output cone；The cone nut line of first transmission cone is parallel with the cone nut line of the second transmission cone.

The course of work：
In conical ring transmission process, when transmission ring is bored with this lateral transmission of inflow of speed at some tapered joint contact
During small extreme direction deflection, transmission ring moves the shaft shoulder direction that small end is bored to transmission.When transmission ring contact the shaft shoulder when, transmission ring with
There is first make contact between the shaft shoulder, while have the second contact point between transmission ring and poppet surface, first make contact to axis of cone line
Distance is the first contact radius, and the distance of the second contact point to axis of cone line is the second contact radius, the first described contact radius
Less than the second contact radius.Therefore, two contact point linear velocities are unequal, and the linear velocity at the second contact point of transmission ring is more than the
New deflection will occur for the linear velocity at one contact point, transmission ring, and new yawing moment is opposite with foregoing deviation.Thus, pass
The deviation of rotating ring is corrected, transmission ring transmission the axis of cone to moving direction be also changed, transmission ring and axle can be avoided
The shock of shoulder, avoids parts damages.
Beneficial effects of the present invention are embodied in：When transmission ring is in the shaft shoulder extreme position fortune of input cone or output cone small end
When turning, transmission ring can avoid hitting with the shaft shoulder, avoid parts damages.
