Interior, ball-screw 2 is used as power input shaft；The screw 5 is sleeved on ball-screw 2, and the driving gear group fixes suit
On screw 5；The driven gear group is fixedly set on power output shaft 3, and driven gear group is engaged with driving gear group matches somebody with somebody
Close；The thrust spring 4 is sleeved on the outside of ball-screw 2, and the one end of thrust spring 4 is fixedly connected with by baffle plate with casing 1；Described
The end fixed cover of screw 5 is equipped with thrust bearing 6, and the outer ring of thrust bearing 6 is fixedly connected with by baffle plate with the other end of thrust spring 4.
It is at least two-stage gear between the driving gear group and driven gear group.
The driving gear group is made up of high speed level driving gear 7 and slow speed turbine stage driving gear 8, high speed level driving gear 7
Positioned at centre, slow speed turbine stage driving gear 8 is symmetrically distributed in the both sides of high speed level driving gear 7；The driven gear group is by high speed level
Driven gear 9 and slow speed turbine stage driven gear 10 are constituted, and high speed level driven gear 9 is located at centre, and slow speed turbine stage driven gear 10 is symmetrical
It is distributed in high speed level driven gear both sides.
The high speed level driving gear 7 is corresponding with high speed level driven gear 9, the slow speed turbine stage driving gear 8 and low speed
Level driven gear 10 is corresponding.
The quantity of the thrust spring 4 is two, and two thrust springs 4 are symmetricly set on the two ends of screw 5.
Illustrate the first use process of the present invention below in conjunction with the accompanying drawings：
As shown in figure 1, two-stage gear is used between the driving gear group and driven gear group of the present embodiment, and in master
High speed level driving gear 7 both sides of moving gear group are symmetrically distributed with two slow speed turbine stage driving gears 8, in the high speed of driven gear group
Level driven gear 9 both sides are symmetrically distributed with two slow speed turbine stage driven gears 10, during original state, high speed level driving gear 7 and height
Fast level driven gear 9 is meshed；
Power is inputted from ball-screw 2, the external load of power output shaft 3.Understand screw 5 and thereon high speed level driving gear
7 have the free degree of straight line and rotation both direction on ball-screw 2, and load and pass sequentially through power output shaft 3, high speed level
Driven gear 9 limits screw 5 and thereon the direction of rotation free degree of high speed level driving gear 7, while thrust spring 4 limits screw
5 and the rectilinear direction free degree of high speed level driving gear 7 thereon.
After power inputs ball-screw 2, ball-screw 2 is driven to rotate forward first, when loading smaller, high speed level master
The twisting resistance that moving gear 7 is exported can overcome load resistance and drive high speed level driven gear 9 to rotate, while high speed level driving tooth
The turn-back power born of wheel 7 are not enough to force thrust spring 4 to compress again, now screw 5 and thereon high speed level driving gear 7
The rectilinear direction free degree will be limited by thrust spring 4, and screw 5 and thereon high speed level driving gear 7 are in can only be with ball-screw 2
The state of synchronous axial system, and then drive high speed level driven gear 9 and power output shaft 3 to rotate, the transmission of power is finally completed, this
When running status schematic diagram it is as shown in Figure 2.
When load resistance occur and increasing suddenly, the twisting resistance that high speed level driving gear 7 is exported can not continue to overcome load
Resistance drives high speed level driven gear 9 to rotate, while the turn-back power that high speed level driving gear 7 is born is enough to force thrust
Spring 4 compresses, now screw 5 and high speed level driving gear 7 can be along ball-screw 2 to one side shifting, thrust spring 4 thereon
Be gradually compressed, until high speed level driving gear 7 is disengaged from high speed level driven gear 9, and slow speed turbine stage driving gear 8 with it is low
When fast level driven gear 10 meshes together, the twisting resistance that now slow speed turbine stage driving gear 8 is exported can overcome load resistance again
To drive slow speed turbine stage driven gear 10 to rotate, but the turn-back power that slow speed turbine stage driving gear 8 is born is not enough to continue to force
Thrust spring 4 have compressed, now the screw 5 and rectilinear direction free degree of slow speed turbine stage driving gear 8 will be by compressive state thereon
Thrust spring 4 limit, screw 5 and thereon slow speed turbine stage driving gear 8 return to shape that can only be with the synchronous axial system of ball-screw 2
State, and then drive slow speed turbine stage driven gear 10 and power output shaft 3 to rotate, the continuation transmission of power is finally realized, while also real
Automatic reduction of speed gearshift is showed, running status schematic diagram now is as shown in Figure 3.
When load resistance from large to small when, the twisting resistance that slow speed turbine stage driving gear 8 is exported can also diminish therewith, and slow speed turbine stage
The turn-back power that driving gear 8 is born is not enough to continue to force thrust spring 4 to maintain compressive state, and thrust spring 4 is gradually stretched
Grow and promote screw 5 and slow speed turbine stage driving gear 8 is moved backward along ball-screw 2 thereon, until slow speed turbine stage driving gear 8 with
Slow speed turbine stage driven gear 10 is disengaged from, and high speed level driving gear 7 recovers to engage again with high speed level driven gear 9, simultaneously
Realize automatic speed-raising gearshift.
Similarly, when power input driving ball-screw 2 is rotated backward, running status is ibid.Further, can be according to actual negative
Carry increase in demand gearshift series.
Scheme in embodiment and the scope of patent protection for being not used to the limitation present invention, it is all without departing from carried out by the present invention etc.
Effect is implemented or changed, and is both contained in the scope of the claims of this case.
