Embodiment
Embodiment of the present utility model as shown in Figure 1, Figure 2, Fig. 3, shown in.
The combined type infinitely variable speed transmission of the utility model design mainly comprises oscillating tooth cone pulley and novel metal silent chain.The structural representation of novel metal silent chain as shown in Figure 1, novel metal silent chain is made up of chain link and shank, wherein the end face of chain both sides chain link to be designed to cone dish conical surface bus relative to the inclination angle of vertical direction is same numerical value, both sides chain end face is contacted just with cone dish end face, when cone dish axial grip, chain can bear larger power and non-slip, and the contact of chain and cone dish increases, frictional force increases, and the clamping realizing chain and cone pulley better controls.The top on chain link inclined-plane, two ends and bottom design are fillet, when infinitely variable speed transmission carries out speed-ratio regulation, because the chain that moves axially of cone dish has eccentric phenomena appearance, the wearing and tearing of the chain that the chain bias that can reduce the fillet design of two ends contact edge causes and cone pulley, middle chain link is common metal chain link, all there is sprocket the bottom of all chain links, and chain link connects into chain by shank.
Oscillating tooth gear in the utility model is primarily of cone pulley, oscillating tooth body composition, each oscillating tooth gear has four oscillating tooth bodies, each oscillating tooth body has two oscillating tooth grooves, oscillating tooth groove built with oscillating tooth sheet, as Fig. 2, shown in Fig. 3, oscillating tooth gear has caulking groove along bus, and oscillating tooth body two ends are provided with roller, and roller embeds in caulking groove and can move up and down along caulking groove, moving up and down of oscillating tooth body can promote the change that chain has moved up and down principal and subordinate wheel diameter chain, thus realizes the adjustment of speed ratio.Fig. 2 is the metal chain of oscillating tooth sheet when not engaging with sprocket and the position relationship of oscillating tooth sheet, and Fig. 3 is the metal chain of oscillating tooth sheet when engaging with sprocket and the position relationship of oscillating tooth sheet.
The combined type infinitely variable speed transmission of the utility model design adopts two kinds of kinds of drive, i.e. fricting transmissioning mode and oscillating tooth engagement driving mode.Fricting transmissioning mode is the kind of drive of traditional stepless speed variator, namely rely on hydraulic pressure installation to promote cone dish and move axially grip chain, rely on frictional force between metal chain and cone pulley to carry out the transmission of power, adopt the novel metal silent chain of the utility model design can increase the frictional force of chain and cone pulley simultaneously.Engagement driving mode relies on oscillating tooth sheet to engage transferring power with the sprocket of novel metal silent chain, when oscillating tooth gear reaches certain rotating speed, centrifugal force is enough to when in oscillating tooth groove, slide plate throws away, and oscillating tooth sheet engages with sprocket and is freely formed required profile of tooth, realizes stepless engagement.The utility model adopts the Composite Transmission mode two kinds of kinds of drive combined, namely the different kinds of drive is adopted according to different operating mode, as adopted fricting transmissioning mode in the starting stage, starting stage centrifugal force is not enough to slide plate is thrown away, when namely cannot realize engagement driving, adopt the phenomenon that friction driving can avoid chain to skid, along with the raising of rotating speed, when centrifugal force is enough to oscillating tooth sheet to throw away engagement, can the kind of drive be changed into engagement driving, to realize the transmission of power of large torque, the engagement of oscillating tooth sheet and sprocket as shown in Figure 3.Meanwhile, chain can clamp by fricting transmissioning mode, and controlled the tensioning of chain by the size of hydraulic pressure installation control clamping force, therefore this device does not need other tension device.
