Specific embodiment
As shown in Fig. 2, linear rack gear 1 that this device is mainly connected by two with engine piston 3 and with linear tooth
The semi-circular gear 2 that item 1 is meshed forms, and rack gear does linear reciprocating motion with piston, semi-circular gear 2 is driven to do circumference fortune
It is dynamic, thus output power.It is its complete operation from Fig. 2 to Fig. 4.In Fig. 2, linear rack gear 1 is past from lower dead center
Upper movement drives semi-circular gear 2 to be clockwise to Fig. 3, i.e., arrival rack gear top dead centre, gear rotate 180 degree.Straight line in Fig. 3
Shape rack gear 1 moves downward, and continues that semi-circular gear 2 is driven to be clockwise to Fig. 4, that is, returns to rack gear lower dead center and complete a work
Make process.
The device course of work thus above, but there are also some detailed problems, need to add several servo mechanisms and solve.It asks
Topic and solution are as follows:
1, Fig. 2 into Fig. 4 at A the problem of: will be with linear tooth moving to the movable teeth 2-1 in Fig. 4 at A on gear from Fig. 3
Tooth on 1 left side rack gear of item engages, but during this, the two is to go in the same direction, it may occur that tooth butt can not engage.For solution
Certainly this problem, the movable teeth 2-1 at A are connected with a connecting rod 5, and the other end of connecting rod 5 is vertically fixed with baffle 6, the work at the A
Movable tooth 2-1 is slidably connected with semicircular gear 2 by track 7, and the center rotating of semicircular gear 2 connects a camshaft 8,
Baffle 6 is pushed in the rotation of camshaft 8, moves the movable teeth 2-1 at A along the radial expansion of semicircular gear 2.To real
Now when semi-circular gear 2 turns to a certain position, the movable teeth 2-1 at A is started to shrink into, prevents tooth butt, is rotated another
When a little positions, then the movable teeth 2-1 at A released and the tooth engagement on linear rack gear 1, participates in transmission.And at one
In the course of work, it may appear that the case where shrinking release twice.It shrinks, discharge as shown in Figure 5.
2, the problem of when Fig. 2 to Fig. 4 at B: in Fig. 2, the movable teeth 2-2 at B on gear is nibbled with the tooth on the rack gear of right side
It closes, rack gear moves upwards movable teeth 2-2 at drive and B and rotates counterclockwise and live at A on the right side of from Fig. 2 to Fig. 3 in motion process
Movable tooth 2-1 rotates clockwise just opposite.To solve this problem, movable teeth 2-2 and semicircle as shown in figure 5, at B are answered at B
Type gear 2 separates, and is connect by connector 9 with the center rotating of semicircular gear 2, and the center power of semicircular gear 2 is defeated
There are two camshaft 10,11 and a pinion gear 12, the pinion gears 12 to pass through activity at connecting rod 13 and B for the rotation connection of shaft 4
Tooth 2-2 connection, and engaged with a spur rack 14；The spur rack 14 is slidably connected with semicircular gear 2, and it two is held level with both hands
Row is provided with connecting rod 15, and baffle 16,17 has been respectively fixedly connected in the opposite sides of the connecting rod 15, when the rotation of camshaft 10,11 pushes away
Dynamic baffle 16,17, makes 14 straight reciprocating motion of spur rack, so that pinion gear 12 be driven to rotate, and then controls movable teeth 2-2 at B
Rotate counterclockwise or clockwise, realize the separation or combination of itself and 2 main part of semicircular gear.
And a course of work as shown in Figures 2 to 4, appearance separate the case where recombining again twice.Activity at certain B
It the separation of tooth 2-2 and recombines, can also be realized by planetary gear mechanism.
3, the limit of upper and lower stop.It realizes that rack gear is stationary at upper and lower stop, needs the control of two position-limit mechanisms 18,
Specific structure includes: two camshafts 19,20, and the gag lever post 21 between two camshafts 19,20, the both ends of gag lever post 21
It is respectively equipped with baffle 22,23, for gag lever post 21 by 1 Hard link of connecting rod 24 and two linear rack gears, the rotation of camshaft 19,20 can
Push baffle 22,23 that gag lever post 21 is driven to move up and down；The camshaft 19,20 has been respectively fixedly connected shaft 25,26, shaft 25,
Transmission gear 27,28, the transmission gear 27,28 and the power output shaft 4 for being installed on semicircular gear 2 are coaxially fixed on 26
On driving gear 29 engage.When gag lever post 21 moves to the position of the top, spur rack arrives at top dead centre；Gag lever post 21 moves
When to the lowermost position, spur rack arrives at lower dead center, as shown in Figure 6.
Although it is more complicated than crankshaft-link rod that semi-circular gear 2 is driven structure, rack gear, gear, several cams are mainly increased
Axis, but the friction between associated components, loss problem can solve very well under prior art conditions, in automobile gearbox
There are a large amount of gear drives, inlet and outlet door switch is also controlled by camshaft, and the semi-circular transmission of gear 2 can increase torque and then mention
Rise engine efficiency.
The converter output torque arm of force is the radius R of semi-circle gear 2 at any time, so the arm of force is constant, torque
The pressure change only generated with cylinder so that overall output efficiency be made to greatly improve compared with crankshaft rod structure, and exports and stablizes.Always
For body, the semi-circular transmission of gear 2 is driven better than crankshaft-link rod.
