Detailed description of the invention
For making the purpose of the embodiment of the present invention, technical scheme and advantage clearly, below in conjunction with the embodiment of the present invention and accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described。It should be noted that described embodiment a part of embodiment that is only the present invention, rather than whole embodiment。Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention。
Embodiment
Refer to Fig. 1, the invention discloses a kind of biobelt heavy duty buncher, including the first speed governing rotating disk 4, actively rotating disk 2, driven turntable, the second speed governing rotating disk 5, steel belt 3, driving shaft 1, driven shaft the 8, first hydraulic speed regulating device and the second hydraulic speed regulating device；Driving shaft 1 and driven shaft 8 be arranged in parallel, and actively rotating disk 2 and driving shaft 1 are in transmission connection, and driven turntable and driven shaft 8 are in transmission connection；Actively rotating disk 2 is all the conical surface with the two sides of driven turntable, and the tapering on two sides is equal；Two the first speed governing rotating disk 4 mirror symmetries are placed in the left and right sides of actively rotating disk 2, and the first speed governing rotating disk 4 is slidably connected with driving shaft 1, and the outside of the first speed governing rotating disk 4 is equiped with the first hydraulic speed regulating device；Two the second speed governing rotating disk 5 mirror symmetries are placed in the left and right sides of driven turntable, and the second speed governing rotating disk 5 is slidably connected with driven shaft 8, and the outside of the second speed governing rotating disk 5 is equiped with the second hydraulic speed regulating device；Article two, steel belt 3 is around the both sides being connected on actively rotating disk 2 and driven turntable, and respectively by the first speed governing rotating disk 4 and the second speed governing rotating disk 5 axial compression。
The ultimate principle of buncher is to utilize friction to carry out transmission, realizes different gear ratios by adjusting the friction radius size of drive disk assembly。Owing to the adjustment of this friction radius is stepless, freely, uniformly, the adjustment change of arbitrarily gear ratio in variable range therefore can be realized。But relatively, frictional drive has the characteristic that overload is skidded, and the torque load of transmission has bigger restriction。Once at the higher heavily loaded environment of load, buncher is easy to skid。
Prior art has a kind of buncher, transmits moment of torsion only with wall scroll steel belt 3, and the effective skin friction of generation is limited all the time, so transferable moment of torsion is less。Consequent problem is, buncher has to reduce gear ratio with the increasing square that slows down, drive equipment such as motor, electromotor etc. then to need higher power to raise speed to realize accelerating transition, the gear ratio of buncher could improve in the transition of delayed ground, has thus resulted in the problem that power consumption is higher, be unfavorable for heavy duty driving。
The biobelt heavy duty buncher of the present invention adopts the structure of double; two steel belt 3, the transmission principle of steel belt 3 is to utilize the oppressive force between the first speed governing rotating disk 4 and active rotating disk the 2, second speed governing rotating disk 5 and driven turntable to ensure friction, its principle is similar to the effect between the friction plate of disc brake and friction clamp, it is desirable to oppressed steel belt 3 has certain intensity and wear-resisting。At this, material of steel belt 3 is not construed as limiting。When two the first speed governing rotating disks 4 are by the first hydraulic speed regulating device effect compressing, owing to the spacing between active rotating disk 2 and the first speed governing rotating disk 4 reduces, and actively rotating disk 2 is tapered, the frictional drive radius of steel belt 3 can increase, in like manner, corresponding second hydraulic speed regulating device that regulates makes the spacing between driven turntable and the second speed governing rotating disk 5 increase accordingly, so that the friction radius of steel belt 3 reduces, can complete to increase the speed regulation process of gear ratio。The operation reducing gear ratio is completely reverse with said process。
The structure of double; two steel belts 3 provides many one and retransmits kinetic force of friction, is more conducive to improve driving torque, thus the skidding reduced in transmission process, makes that driving equipment is more constant at one, provides power under the operating mode of lower power, saves energy consumption。Remain again the stepless speed governing characteristic of stepless transmission simultaneously, eliminate the pause and transition in rhythm or melody sense in speed-change process。Owing to being the structure of double; two steel belt 3, article two, the machining accuracy coordinating needs certain between steel belt 3 with each drive disk assembly coordinates, and need actually used break-in, principle is similar to piston and the cylinder of electromotor, when therefore generally keeping in repair, the installation site of steel belt 3 can not arbitrarily be exchanged, and otherwise can affect reliability and the balance of transmission。
As preferably, described steel belt 3 is saved gear unit series connection link by plural number and forms, the form and dimension of each gear unit is all equal, the cross section of gear unit is trapezoidal, and the one side angle of inclination of being close to actively rotating disk 2 and driven turntable is equal with the tapering of active rotating disk 2 and driven turntable, the first speed governing rotating disk 4 and the second speed governing rotating disk 5 is close in another side。
Owing to steel belt 3 needs to bear oppressive force, general flexible material is poorly suitable for the structure of the present invention。Its one side being close to actively rotating disk 2 and driven turntable tilts, then with the surface profiles of active rotating disk 2 and driven turntable, according to geometrical principle, when the spacing of the first speed governing rotating disk 4 and the second speed governing rotating disk 5 changes, can there is sliding diametrically in steel belt 3, thus completing speed governing。The angle of inclination of above-mentioned each parts is not especially limited at this, can be designed according to actual condition。
As one of which preferred version, described first speed governing rotating disk 4 and the second speed governing rotating disk 5 are in circular planar disk-like, and the one side that described gear unit is close to the first speed governing rotating disk 4 and the second speed governing rotating disk 5 is vertical with axial direction。
Under this scheme, the first speed governing rotating disk 4 and the second speed governing rotating disk 5 are comparatively direct to the oppressive force effect of steel belt 3, cut the pressure basic role of steel belt 3 on active rotating disk 2 with driven turntable, are conducive to moment of torsion to transmit。But owing to pressure is relatively big in speed regulation process, cause the speed governing sliding of steel belt 3 and have some setbacks。
As alternative preferred version, described first speed governing rotating disk 4 and the second speed governing rotating disk 5 are in the cone protruded, described gear unit is close to the one side of the first speed governing rotating disk 4 and the second speed governing rotating disk 5 and is tilted with axial direction, and angle of inclination is equal with the tapering of the first speed governing rotating disk 4 and the second speed governing rotating disk 5 surface。
Under this scheme, appropriateness makes the first speed governing rotating disk 4 and the taper at an angle of the second speed governing rotating disk 5, it is simple to provides certain radial forces to steel belt 3, is conducive to speed governing。Shortcoming is that steel belt 3 has the pressure loss of part on the surface of the first speed governing rotating disk 4 and the second speed governing rotating disk 5, makes the reduction that effectively rubs, reduces transferable moment of torsion。
As preferably, described first hydraulic speed regulating device includes the first hydraulic cylinder 6 and thrust bearing, and the first hydraulic cylinder 6 is located at the dorsal part of the first speed governing rotating disk 4 by thrust bearing top；Described second hydraulic speed regulating device includes the second hydraulic cylinder 7 and thrust bearing, and the second hydraulic cylinder 7 is located at the dorsal part of the second speed governing rotating disk 5 by thrust bearing top。Guarantee that the pressure of the first hydraulic cylinder 6 and the second hydraulic cylinder 7 will not hinder the rotation of the first speed governing rotating disk 4 and the second speed governing rotating disk 5 by thrust bearing。
As preferably, between described first speed governing rotating disk 4 and driving shaft 1, being also fixed with sliding bearing between the second speed governing rotating disk 5 and driven shaft 8。Generally, rotate together with the transmission that first speed governing rotating disk 4 is as steel belt 3 with the second speed governing rotating disk 5, velocity of rotation is very fast, and the first speed governing rotating disk 4 and the second speed governing rotating disk 5 need to move axially in speed regulation process, but motion amplitude axially is little, speed is slow, and only occurs when speed governing。The characteristic of sliding bearing is employing oil lubrication between inner ring and outer ring, and when the speed rotated is sufficiently large, according to fluid mechanics principle, lubricating oil can produce supporting force makes the inner ring of sliding bearing and outer ring disengage, and reaches the rotating effect of the best。Meanwhile, the inner ring of sliding bearing allows the axially-movable of certain amplitude with outer ring, meets the first speed governing rotating disk 4 and the second speed governing rotating disk 5 needs of axial slip in speed regulation process。
A kind of biobelt heavy duty buncher provided by the present invention, adopts the structure of double; two steel belt 3 to improve effectively friction, it is achieved heavy duty variable transmission, is conducive to transmitting bigger moment of torsion, and transmission process skids few, and reliable transmission is high。Power drive device such as motor, electromotor constant power change less, adopt lower rated power premise under realize uniform speed change, make power drive device operate an operating mode more constant, less, to saving energy consumption have remarkable effect。And overall structure is simple, it is easy to volume production, maintaining is convenient, and cost is relatively low。
Embodiment described above only have expressed one embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention。It should be pointed out that, for the person of ordinary skill of the art, without departing from the inventive concept of the premise, it is also possible to making some deformation and improvement, these broadly fall into protection scope of the present invention。Therefore, the protection domain of patent of the present invention should be as the criterion with claims。
