Two gears of speed changer（Neutral gear can be set）.
The utility model has simple in structure, compact, and appearance and size is small, light-weight, and technical indicator is more advanced, using can
Lean on, it is convenient to install and maintain, it is at low cost the features such as.
Description of the drawings
Fig. 1 is the drive mechanism schematic diagram of the utility model.
Specific implementation mode
The utility model is described in detail below in conjunction with attached drawing：Shown in Fig. 1, described in the utility model a kind of two
High speed difference speed changer is kept off, mainly by input shaft 1, level-one sun gear 2, primary planet wheel 3, primary planet carrier 4, ring gear 5, two level
Planetary gear 6, secondary solar gear 7, secondary planet frame 8, shift control mechanism composition；The input shaft 1 and motor or hydraulic pressure horse
Up to connection, which is nibbled by level-one sun gear 2 connected thereon and the primary planet wheel 3 on primary planet carrier 4
It closes；The primary planet wheel 3 is connected with secondary planet wheel 6 by sharing a ring gear 5；It is solid on the primary planet carrier 4
It is connected with secondary solar gear 7, the secondary solar gear 7 is engaged with the secondary planet wheel 6 being nested on secondary planet frame 8；It is described
Secondary planet frame 8 with output shaft flange couple.
The shift control mechanism includes：The ring gear first line of a couplet, which is connected to, manipulates tooth shaft 9, which is connected with sliding
Tooth set 11, and so that the side of manipulation tooth shaft 9 is positioned over the toothholder 10 of shell connection by the sliding gear collar 11, the other side is positioned over
Second level planet carrier couples toothholder 12；Ring gear connection manipulations tooth shaft 9, couple with shell toothholder 10, sliding gear collar 11, and
Toothholder 12, the output flange 13 of output shaft connection.
When due to ring gear stop, speed changer just becomes the retarder of secondary planet transmission, and speed ratio is that 2 planets pass
The product of dynamic speed ratio, reduction ratio can reach 25-35 or even bigger；When ring gear and secondary planet frame（Output shaft）When connection,
Planet carrier, ring gear, sun gear are integral, rotate together, at this point, speed ratio is 1, i.e., it is identical as output rotating speed.Speed difference is I gear speed
Than divided by II keep off speed ratio, such speed difference can reach 25-35, realize high speed difference.
Embodiment：Two gears high speed difference speed changer described in the utility model, it includes to couple with motor or hydraulic motor
Input shaft, secondary planet transmission, shift control mechanism, and the output shaft and output flange that couple with second level planet carrier；
The shift control mechanism of the two gear high speed difference speed changers can be shift fork tooth noose according to use occasion difference
Structure can also be hydraulic friction clutches liquid structure, only by operating mechanism, dynamic could can export.
The two gear high speed difference transmission input shafts couple with the sun gear that primary planet is driven, primary planet transmission
Planet carrier couples with the sun gear that secondary planet is driven, and primary planet transmission shares ring gear, and internal tooth with secondary planet transmission
Circle connection is used as operating mechanism vital part, by making it couple with shell（Stop）, or couple with output shaft（At the same speed）It realizes
Two gears of speed changer（Neutral gear can be set）；It specifically includes：
Shown in Fig. 1, the utility model mainly by input shaft 1, level-one sun gear 2, primary planet wheel 3, primary planet carrier 4,
Level-one two level shares the manipulation tooth shaft that ring gear 5, secondary planet wheel 6, secondary solar gear 7, secondary planet frame 8, ring gear couple
The compositions such as the toothholder 10, sliding gear collar 11, the toothholder 12 coupled with output shaft, the output flange 13 that 9, couple with shell.
Input power is by the input shaft 1 that couples with motor or hydraulic motor, until level-one sun gear 2, reaches primary planet wheel
3, ring gear 5 enters secondary solar gear 7 by the output of primary planet carrier 4, ring gear 5 and second is reached by second level planetary gear 6
Grade planet carrier 8, second level planet carrier couples with output shaft flange, defeated since 3 components are at free state in Gear Planet Transmission
Go out the output that shaft flange 13 does not determine.Connection manipulates tooth shaft 9 on sharing ring gear, and places sliding gear collar 11, manipulates tooth
The toothholder 10 coupled with shell is placed in the side of axis 9, and placing second level planet carrier in the other side couples toothholder 12.When control stick is grasped
Even if sliding gear collar 11 shifts to toothholder 10, since toothholder 10 is integrally fixed on shell, make ring gear also locking, at this moment two gears are big
Speed difference speed changer becomes the retarder of secondary planet transmission, and speed ratio is the product of 2 Gear Planet Transmission speed ratios, and speed ratio is reachable
25-35 or bigger；When joystick manipulation sliding gear collar 11 shifts to toothholder 12, since toothholder 12 couples with the second planet carrier, make
Ring gear and the same rotating speed of the second planet carrier, in such Gear Planet Transmission, when two component rotating speeds are identical, the rotating speed of third component
It is identical, so that Gear Planet Transmission is become a rotor, synchronized to rotate, speed ratio at this time is 1, the speed obtained by the movement of control stick
It is just very bigger than difference.
Two gear high speed difference speed changer described in the utility model is, it can be achieved that vehicle fast running, slowly movement（In operation
It is mobile）It works under equal working environments.Test bench location is can also be used for test special equipment（Low-speed big experiment, high speed
Light duty test）Etc. occasions, it is above due to having the characteristics that, to make the structure novel of two gear high speed difference speed changers, compact, function
It is more, it can preferably meet the requirement of the actual conditions such as special vehicle, platform position.
