Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following instance is used for illustrating the utility model, but is not used for limiting scope of the present utility model.
In description of the present utility model, it should be noted that, orientation or the position relationship of the indication such as term " left side ", " right side " are based on orientation shown in the drawings or position relationship, only the utility model and simplified characterization for convenience of description, rather than indicate or imply that the device of indication or element must have specific orientation, with specific orientation, construct and operation, therefore can not be interpreted as restriction of the present utility model.
Conical surface line: refer to the line between the same angle of circumferential edges of two circular sections of cone dish.
As illustrated in fig. 1 and 2, the utility model stepless speed variator, comprises main shaft 1, the output shaft 4 parallel with main shaft 1; Be fixed on the end initiative taper dish 2 concentric with main shaft 1 of main shaft 1, the end that is fixed on output shaft 4 and output shaft 4 concentric from mantle dish 5, initiative taper dish 2 is with identical from the tapering of mantle dish 5, and both conical surfaces arrange in opposite directions; Be arranged on initiative taper dish 2 and between mantle dish 5 and respectively with initiative taper dish 2 with from the driving component 3 of mantle dish 5 rolling friction transmissions, driving component 3 is transmission ball; And moving assembly 6, moving assembly 6 drives driving component 3 to move along initiative taper dish 2 with from the conical surface line of mantle dish 5.
Initiative taper dish 2 with from the conical surface of mantle dish 5, arrange in opposite directions, because the tapering of two cone dishes is identical, immediate conical surface line parallel between two conical surfaces (being that the conical surface is parallel), driving component 3 respectively with initiative taper dish 2 with from mantle dish 5, contact, by rolling friction transmission.As shown in Figure 2, when initiative taper dish 2 is rotated in the forward, the driving component 3 of contact rotates backward with it; Counter-rotational driving component 3 drive contact with it from the 5 forward transmissions of mantle dish, thereby complete by initiative taper dish 2 to the transmission from mantle dish 5.At any time, the linear velocity of initiative taper dish 2 and driving component 3 point of contact circular sections is with identical from the linear velocity of mantle dish 5 and driving component 3 point of contact circular sections, i.e. ω 2r 25r 5(r 5and r 2refer to initiative taper dish 2 and the radius with driven member 3 circular sections, point of contact place from mantle dish 5), the velocity ratio=ω of main shaft 1 and output shaft 4 1/ ω 42/ ω 5=r 5/ r 2.Therefore only need to change r 5and r 2size just can change velocity ratio, in the situation that the constant rotational velocity that changes output shaft 4 of the rotating speed of main shaft 1.By moving assembly 6, drive driving components 3 to move along the conical surface line of the conical surface, thereby change driving component 3 with initiative taper dish 2 with from the point of contact between mantle dish 5, thus change r 5and r 2, change velocity ratio, realize speed change.The method that changes point of contact by driving component 3 is continuous, is a kind of stepless change.
Stepless speed variator of the present utility model, adopts two cone dishes and rolling friction driving component to carry out transmission, by changing the position of driving component, changes velocity ratio, and more present technology adopts the structure of four cone dishes comparatively simple, and cost is lower; By moving assembly, control the position of driving component, only need to control driving component and move, compared with prior art, need to control the position of two removable cone dishes, greatly simplified control procedure; Compared with prior art, point of contact is restricted less, and velocity ratio excursion is larger; Parts are less, and space is arranged comparatively compact, and speed changer is smaller and more exquisite.
As shown in Figure 3, moving assembly comprises shifting axle 8, power end cap 7, positioning end cover 9 and hydraulic package (not shown), the axis of shifting axle 8 and initiative taper dish 2 and from the conical surface line parallel of mantle dish 5, the two ends of shifting axle 8 are nested in respectively in power end cap 7 and positioning end cover 9; Power end cap 7 is provided with hydraulic pressure cavity 12, and hydraulic pressure cavity 12 is connected with hydraulic package by oilhole 13; In positioning end cover 9, be nested with elastic component 10, elastic component 10 tops press shifting axle 8 to be arranged in one end of positioning end cover 9; Driving component 3 is arranged on shifting axle 8, with 8 while of shifting axle moving axially along shifting axle 8.
When hydraulic package is pressed into hydraulic oil by oilhole 13 in hydraulic pressure cavity 12, utilize the pressure of hydraulic pressure to overcome the elastic force of elastic component 10, driving component 3 is moved right with shifting axle 8; When hydraulic package Extract force feed, the masterpiece used time with no pressure, elastic component 10 recovers, and driving component 3 is moved to the left, and returns to initial position.When controlling speed changer, only need to control hydraulic package and can change the position of point of contact to force feed in hydraulic pressure cavity 12 or oil pumping, just can change contact radius, realize stepless change, simple to operate, it is convenient to control, lower to the control accuracy demand of controller.
As shown in Figure 4, driving component 3 is rotatably installed on shifting axle 8, and the two ends of driving component 3 are provided with axial direction positioning device 11.Axial position between driving component 3 and shifting axle 8 is fixed, and driving component 3 can rotate along shifting axle 8.During speed changer work, the moment of rotation of transmission only needs to overcome driving component 3 actings, does not need to overcome shifting axle 8 actings, and the merit of consumption is less, is conducive to greatest extent the moment of main shaft 1 is sent to output shaft 4, by output shaft 4, is outwards exported.
Preferably, elastic component 10 is selected helical spring.Helical spring has good recovery capability, and is widely used, and selects conveniently.
As shown in Figure 5, driving component 3 also can be selected transmission cylinder.Use transmission cylinder to carry out transmission, surface of contact is larger, is not easy to skid, and is applicable to the speed changer that driving torque is larger.
