stayed between each component Gap and the gap how is fixed, is just not elaborating herein of being easily achieved.

The running component actuation of the speed changer, driving wheel gear ring and the diameter change of driven wheel gear ring are always opposite； 2 speed change shaft gear rotation directions on main shaft are opposite；2 speed change shaft gear rotation directions on counter shaft are Opposite；When main shaft rotates, the axial action direction with 2 progress wheels that main shaft is threadedly engaged is opposite；Become When fast countershaft rotates, the axial action direction with 2 progress wheels that counter shaft is threadedly engaged is opposite；The change of the speed changer Speed is that the driven wheel diameter ring gear that become larger by driving wheel diameter ring gear becomes smaller or the driving wheel diameter ring gear driven wheel gear ring that becomes smaller becomes larger And it completes；When gear ring becomes smaller, due to the non-telescoping property of transmission belt, transmission belt can grow corresponding length than gear ring perimeter, The transmission belt of the length can be released between 3 axis and 4 axis, only when 3 axis and 4 axis are not transmitted with adjacent connection, ability The transmission belt for growing part is transferred out of, the gear ring that the transmission belt being transferred out of can be become larger by another receives；When gear ring becomes larger, Transmission belt on gear ring needs to increase, and due to the non-telescoping property of transmission belt, the transmission band part for needing to increase can be in 3 axis and 4 It extracts between axis, only when 3 axis and 4 axis are not transmitted with adjacent connection, could be obtained from the gear ring and tensioning wheel to become smaller； When two gear rings are not in synchronous change diameter, one of gear ring release or need to extract transmission strip length by tensioning wheel Carry out adjustment of handling up；Annular gear teeth and interaction (phase with the tooth of its (annular gear teeth) intermeshing transmission belt or roller bearing Mutually push) transmit power；3 axis with the rotation direction of 4 axis rotations be it is opposite, the region (indexing) between 3 axis and 4 axis is exactly The speed-change area；The cathode of all electric appliances of the speed changer is normal open electricity；When gear ring is in minimum state, pinion gear and pinion gear Between will not still touch." the adjacent connection " refer to, two pinion gear adjacent connection, that is, two pinion gears Between be not separated with the connections of other pinion gears.The speed change execution position refers to that combination wheel is gone in the combination wheel on 3 axis and 4 axis Position of pinion gear when not being transmitted with adjacent connection.

The operation of the speed changer and speed change and component actuation are that driving wheel receives external rotational power through power transmission shaft Input and rotate, driving wheel imparts power to transmission belt through gear ring, the gear ring that transmission belt imparts power to driven wheel make from Driving wheel receives power and rotates, and driven wheel exports rotational power through power transmission shaft；Speed changer in operation, when driving wheel or from When driving wheel goes to variable-ratio position (speed change execution position), triggering magnet on power transmission shaft can be closer to corresponding tongue tube And it is closed the tongue tube, the tongue tube on driving wheel and driven wheel is asynchronous closure (there is also synchronizing closes sometimes)；Turn Dynamic master control main shaft can assign gear-shift command, switch to increase shelves instruction to the left, switch to downshift command to the right；When rotation master control main shaft, The power is passed to master control countershaft through master control gear simultaneously by master control main shaft, and master control countershaft can be with the direction opposite with master control main shaft The rotation of same amplitude is made, the revolving speed of master control main shaft and master control countershaft is equal at this time but rotation direction is opposite；Master control main shaft With the rotation of master control countershaft, straight line shifting is done with the switch frame being threadedly engaged with its (master control main shaft and master control countershaft) by pushing respectively (switch frame is switched on and off the limit of frame limiting slot, cannot follow the master control main shaft or master control countershaft connecting with its (switch frame) for movement Rotation, switch frame can only do linear reciprocation movement)；The switch frame that master control main shaft and master control countershaft are pushed, direction of action are mutual Mutually opposite (instructs then: the switch frame that the promotion of master control main shaft is connect with the master control main shaft mobile, master control to the left side if it is shelves are increased Countershaft pushes the switch frame connecting with the master control countershaft mobile to the right；Then if it is downshift command: master control main shaft pushes and should The switch frame of master control main shaft connection is mobile to the right, and master control countershaft pushes the switch frame connecting with the master control countershaft to move to the left side It is dynamic)；The movement of switch frame can make corresponding master switch press to progress wheel driving lever, while compression reseting spring, to keep in master control The variable-speed dynamic (the contained spring elastic force that the elastic force of reset spring is greater than master switch) that main shaft transmits；It is instructed if it is shelves are increased, It is at this time closed state (energization shape with one group of master control main shaft of right master switch and with one group of master control countershaft of left master switch State)；If it is downshift command, the right master switch with one group of master control main shaft of left master switch and with one group of master control countershaft at this time For closed state (energized state).The closure of tongue tube at this time will make connect with the tongue tube 2 master switches connect electricity Source, wherein the master switch of closed state makes corresponding relay power work.Contact closure is made corresponding electricity by the relay Magnetic pressure disk powers on and works；Electromagnetism platen powers on work, will push speed change shaft gear and friction plate and clutch seated connection Touching, variable-speed shaft gear band movable friction plate and clutch seat rotate together at this time.The rotation for the clutch seat that main shaft is connected, by band Dynamic main shaft rotates together；The rotation for the clutch seat that counter shaft is connected will drive counter shaft to rotate together.Increasing shelves In instruction, the rotation of main shaft will be that the progress wheel being threadedly coupled with it is pushed to do among axis by the effect of screw thread Mobile movement；The rotation of counter shaft will be that the progress wheel being threadedly coupled with it is pushed to do to axis by the effect of screw thread The mobile movement in both ends.In downshift command, the rotation of main shaft will be by the effect of screw thread, pushes and it is connected with screw thread The progress wheel connect does the movement mobile to axis both ends；The rotation of counter shaft will be by the effect of screw thread, pushes and it is with spiral shell The progress wheel of line connection is done to movement mobile among axis.Progress wheel is by progressive push rod connected to it and pawl seat outer rim Bearing, which is passed into the pawl seat on driving wheel and driven wheel and so that the pawl seat is made corresponding movement (that is: increasing shelves refer to In order, 2 pawl seats on driving wheel draw close direction movement to wheel disc, and 2 pawl seats on driven wheel are moved to the direction far from wheel disc It is dynamic；In downshift command, 2 pawl seats on driving wheel are mobile to the direction far from wheel disc, and 2 pawl seats on driven wheel are leaned on to wheel disc It is mobile to hold together direction).2 pawl seats on driving wheel push the pawl foot connecting with the claw bar of the pawl seat by claw bar respectively, and with this Pinion gear axle bed, profile modified gear, pinion gear, pawl foot locking plate on the pinion shaft and the pinion shaft of the connection of pawl foot, take turns The movement that moves radially of disk (in increasing shelves instruction, does the movement from wheel disc axle center to outer rim direction, gear ring realization is made to become larger Movement；In downshift command, the movement from wheel disc outer rim to axis direction is done, the gear ring is made to realize the movement to become smaller), and make tooth The perimeter of circle realizes the variation of setting；Displacement rack gear through being fixed on wheel disc simultaneously converts the straight line power of profile modified gear At rotational power；It drives pinion shaft and pinion gear with corresponding rotational motion, and corrects transmission strip length and gear ring perimeter Difference and the tooth dislocation between transmission belt and pinion gear.2 pawl seats on driven wheel push the pawl with the pawl seat by claw bar respectively The pawl foot of bar connection, and pinion gear axle bed on the pinion shaft and the pinion shaft that are connect with the pawl foot, profile modified gear, Pinion gear, pawl foot locking plate, wheel disc move radially movement and (in increasing shelves instruction, do the shifting from wheel disc outer rim to axis direction It is dynamic, so that the gear ring is realized the movement to become smaller；In downshift command, the movement from wheel disc axle center to outer rim direction is done, makes the gear ring Realize the movement to become larger), and the perimeter of gear ring is made to realize the variation set；The displacement rack gear through being fixed on wheel disc will become simultaneously The straight line power of position gear is converted into rotational power, drives pinion shaft and pinion gear with corresponding rotational motion, and corrects and pass Dynamic band misplaces with the tooth between the difference and transmission belt and pinion gear of gear ring.When driving wheel or driven wheel go to speed change execution position position (per revolution just once speed change execution position), the triggering magnet on power transmission shaft can be closer to and its (the triggering magnet) Corresponding tongue tube is simultaneously closed the tongue tube, so that a series of shift movement is repeated, until progress wheel driving lever is no longer It is closed master switch.When triggering magnet turns to non-speed change execution position with power transmission shaft, tongue tube will be switched off circuit.Tongue tube Disconnecting circuit will make electromagnetism platen stop working and (return to original state), and speed change shaft gear is to separate shape with friction plate and clutch seat State, at this time shift movement terminate and are restored to normal drive state.Master switch carries out temporary master control main shaft by reset spring It make rapid and significantly acts；Then the turnning circle for cooperating driving wheel and driven wheel, carries out repeatedly orderly implementation With the entire gear shifting operation of completion.In non-speed change, resistance gauge prevents main shaft and counter shaft rotation；Change has been crossed in speed change Fast execution position, resistance gauge absorb the rotator inertia of main shaft and counter shaft, and main shaft and counter shaft is prevented to continue Rotation.Brake in resistance gauge remains that effective resistance turns resistance.

In summary the speed changer of the invention engages biography with toothed belt with transmission chain or toothed belt using sprocket wheel Dynamic, transmission efficiency may be up to 85% or more；In the structure of the speed changer, under the action of shift claw, driving wheel and driven rotation Dynamic part is all to maintain balance under any working condition, as long as part processing is accomplished to control precision (size and quality).? In speed changer operation, " centrifugal force " that the movable part of speed changer generates will not be loaded on the belt.It is transported in the speed changer It can be seen that, driving wheel and driven wheel have been in row, the sprocket wheel and transmission chain or toothed belt and toothed belt of general type Drive connection, it is existing mature technology that this drive connection, which reaches 2000r/min revolving speed,.Wherein using transmission chain and sprocket Large-torsion transmisson and existing mature technology may be implemented.In engagement system connection, the factor of component sizes (get over by component Can bear and transmit greatly bigger torque), it can accomplish very little or not influence transmission efficiency；It can be seen that the buncher is in height Still there is Large-torsion transmisson ability under transmission efficiency.The speed changer realize in high revolving speed smooth and efficient operation (speed change with Transmission), and can realize the purpose of transmitting large torque power.Simultaneously also achieve the speed changer driving wheel and driven wheel it Between, it can continuously be recalled in the case where power does not depart from state, any torque ratio and corresponding rotating ratio in setting range.Driving wheel and Rotating ratio and torque ratio transition activities between driven wheel are also equal to the increasing shelves and the shift-down action (change of driving wheel gear ring It is big and driven wheel gear ring to become smaller, it will make under driving wheel original revolving speed and torque, secondary speed gets higher torque and becomes smaller；Drive the gear teeth Circle become smaller and driven wheel gear ring becomes larger, will make under driving wheel original revolving speed and torque, the secondary speed torque that is lower becomes larger). Invention achieves expected purposes.
