Specific implementation mode
The present invention is described in detail below in conjunction with the drawings and specific embodiments, but the present invention is not limited to following embodiments.
One end of crank 3 is fixedly connected with main shaft 1 in Fig. 1, and the other end is fixedly connected with moving axis 7.Sliding block 6 is fixed with countershaft 5
Connection, the equal length of the distance and crank 3 of countershaft 5 to main shaft 1, the length of sliding block 6 are more than the thickness of opening flute length+sliding block 6.
It is fixedly connected axle sleeve 9 at the middle part of half bull stick 8, there is the longitudinal chute along rod axis direction on half bull stick 8, the longitudinal chute
Length has to be larger than 4 times of the length of crank 3, and longitudinal chute passes through axle sleeve 9, corresponding notch is formed in one end of axle sleeve 9.Half
8 one side of bull stick can be rotated by axle sleeve 9 and 7 clearance fit of moving axis around moving axis 7；On the other hand pass through longitudinal chute and cunning
6 clearance fit of block can be slided along sliding block 6.
Engine driving main shaft 1 rotates, and main shaft 1 drives crank 3 to be rotated with rotating speed Ω, is connected in the moving axis 7 of 3 end of crank
The movement of half bull stick 8, while constraint of the movement of half bull stick 8 also by the sliding block 6 being placed in longitudinal chute are driven by axle sleeve 9,
Half bull stick 8 is thus generated not only around the rotation at 5 center of countershaft but also relative to the movement at the center, the angular speed of rotation is Ω/2.
Fig. 2 is the overlooking structure diagram of the half-rotating mechanism of dead axle V belt translation of the present invention.Main shaft 1 is parallel with 5 axis of countershaft,
It is separately mounted in rack 12, it can be relative to gantry rotation.The small transmission wheel 13 and large drive wheel 4 being generally aligned in the same plane use tooth
Shape belt wheel or sprocket wheel are fixedly connected with main shaft 1 and countershaft 5 respectively, transmission belt 2 use tooth form synchronous belt or chain, while with it is small
Driving wheel 13 and large drive wheel 4 engage.
Half bull stick 8 and axle sleeve 9 are fixedly connected by welding manner or interference fit, the axis weight of moving axis 7 and axle sleeve 9
It closes, the cylindrical surface of moving axis 7 and the internal surface gaps cooperation of axle sleeve 9 can realize that relative rotation, the end of moving axis 7 are contacted with baffle 10
Blending bolt 9 is fixed against axle sleeve axial float.
When position of the moving axis 7 close to countershaft 5, the open slot entrance on moving axis 7 is connected to the longitudinal chute of half bull stick 8,
The front end of sliding block 6 enters the open slot of moving axis 7, and the rear end of sliding block 6 is contacted with the longitudinal chute of half bull stick 8；And the rear end of sliding block 6
Into the open slot of moving axis 7, the front end of sliding block 6 is contacted with the longitudinal chute of half bull stick 8.
Due to the pulling force energy balance slide block front end of transmission belt or the contact force of rear end, when moving axis 7 can be improved close to countershaft 5
Mechanism bearing capacity.Since small transmission wheel 13 and the speed ratio of large drive wheel 4 are 2, the rotating speed of sliding block constrains the rotating speed of half bull stick, from
And avoid the uncertainty for instantaneous half bull stick 8 rotation that moving axis 7 is overlapped with countershaft 5.
