Abstract
Disclosed is a 'double cone gear rack gear change device'. According to the 'double cone gear rack gear change device', a novel 'double cone gear rack gear synchronous rotation combination device' is adopted. Through the fact that a sliding gear moves up and down along an inclined plane between two cones and under the function of adding or reducing of the gear rack of the cone, rotating speed of the sliding gear is increased or decreased. The 'double cone gear rack gear change device' is used in existing cars and motorcycles, and stepless speed change of a gear is achieved. Further, the problems large weight, large size and complex structure of an existing speed changer are overcome. Meanwhile, the defect that the existing speed drives depending on friction is also overcome.
Description
The present invention relates to " bicone tooth bar speed change gear ", is that the inventor is about the innovation and creation " cone cage tooth bar speed change gear " by name of proposition on 07 10th, 2012; Application number is to be to transform on the principle basis of applying for a patent in 07 month 10 days in 2012 to form 201210236056.8 applyings date.What " cone cage tooth bar speed change gear " adopted is tooth bar, speed change tooth bar, speed change friendship place assembly, restricted by the speed change intersection during rotation speed change, can not move up and down speed change, makes this device can not be applied to the automobile aspect.Disadvantage that Here it is " cone cage tooth bar speed change gear ".
" bicone tooth bar speed change gear " that this name proposes just solved above shortcoming, original " single cone, tooth bar, speed change tooth bar, the combination of speed change intersection " made into " bipyramid, rack combination ", removed original speed change tooth bar and speed change tooth bar intersection assembly " steady when the rotation speed change, greatly improved rotational speed.
" bicone tooth bar speed change gear " provided by the present invention, it is a kind of by left cone 1, left cone tooth bar 2, left cone loam cake 3, left cone upper shaft hole 4, axle 5 on the left cone, left cone lower cover 6, left cone lower shaft hole 7, left cone lower shaft 8, the synchronous umbrella gear 9 of left cone lower shaft, right cone 10, right cone tooth bar 11, right cone loam cake 12, right cone upper shaft hole 13, axle 14 on the right cone, right cone lower cover 15, right cone lower shaft hole 16, right cone lower shaft 17, the synchronous umbrella gear 18 of right cone lower shaft, middle vibration gear 19, middle vibration axis hole 20, middle vibration axle 21, middle synchronously angular wheel shaft 22, middle synchronously umbrella gear axis hole 23, middle synchronously umbrella gear 24, the mechanism that framework 25 forms.Further specify structure characteristic of the present invention and purpose below in conjunction with accompanying drawing.
Brief Description Of Drawings:
Fig. 1 is the basic structure schematic representation of " bicone tooth bar speed change gear " provided by the present invention.
Fig. 2 is the basic structure plan view of " bicone tooth bar speed change gear " provided by the present invention.
Fig. 3 is the basic side view of " bicone tooth bar speed change gear " provided by the present invention.
Fig. 4 is the basic rear view of " bicone tooth bar speed change gear " provided by the present invention.
Fig. 1, Fig. 3, Fig. 4 also are speed change elemental motion figure of the present invention.
Please see Figure 1, Fig. 2, Fig. 3, Fig. 4, shown in, it mainly is in framework 25, have respectively to be with the tooth bar 2 and 11 that spacing, size, number equate above two cones 1 and 10, around being fixed on cone 1 and 10, and and 19 interlocks of vibration gear; When vibration gear 19 can tooth bar 2 intervals on cone 1 and 10 rotates vibration up and down, tooth bar and 19 interlocks of vibration gear of one side are arranged all the time, under three synchronous umbrella gear 9,24,18 rotary actions, the tooth bar on the left cone 1 and the tooth bar on the right cone 10 are regular to replace interlock formation one circle unitary closed tooth bar with vibration gear 19; The vibration gear can corresponding change form the whole overlapping tooth bar number of the circle of one on two cones during vibration about in the of 19; Rotate vibration gear 19, under umbrella gear 9,24,18 synchronous effects, left cone 1 and right cone 10 are rotated thereupon, by umbrella gear 24 power output in the middle of lower.When vibration gear 19 was up pushed away, the tooth bar number of a synthetic circle had played acceleration progressively increasing on two cones; When vibration gear 19 was up shifted onto left cone and right cone 3,12 loam cake position, maximum with the diameter of two cones 1 and 10 interlocks, the tooth bar number on the cone 1 and 10 became at most, has played maximum speed.Otherwise, when vibration gear 19 is down shifted onto left cone and right cone 6,15 lower cover position from the top and the diameter of two cones 1 and 10 interlocks minimum, the tooth bar number on the cone 1 and 10 becomes minimum, has played minimum speed.
One of the example of executing of the present invention: should " bicone tooth bar speed change gear " be used for the vapour speed-changing mechanism of motorcycle, and can realize gear stepless speed changing, slewing range is wide; Experimental results show that this device can change arbitrarily riding speed; Large and the easily operation of slewing range; Grade ability is strong; Speed-raising is fast; Save the advantages such as fuel oil.
