Abstract

The design designs the technique of the field of the gear box in mechanical major. Arc gears are meshed; the meshed point completes the smooth gear shifting with the sliding of the arc and the rail so as to achieve the purpose of saving energy. The power is input by a transmission shaft to drive a fixed arc gear to rotate; the fixed arc gear is meshed with a sliding semicircular gear and drives the sliding semicircular gear to rotate; a sliding transmission shaft drives a sliding round platform gear to rotate, the round platform gear is meshed with the fixed sliding semicircular gear and drives the fixed sliding semicircular gear to rotate; and a power transmission shaft outputs the power. The arc of the sliding semicircular gear slides along the arc of the fixed arc gear; the arc of the sliding round platform slides along the arc of the fixed semicircular gear; the sliding transmission shaft slides in the slide rail of the sliding shaft; a sliding car slides in the rail thereof, thus realizing the steppless speed change by changing the meshed radius of the fixed original arc gear and the sliding round platform gear and the sliding round platform gear and the fixed semicircular gear.

Description

Circular arc cutting and slide formula buncher

Technical field:

This design belongs to the technology in mechanical major gearbox field.

Background technique:

Present gearbox is generally gear engagement gearshift and electrodeless variable-speed self shifter. stepless change divide again two kinds a kind of be with steel band or chain transmission; Another kind of automatic transmission is to change with fluid power to adjust gear transmission, the realization gear shift.

Summary of the invention:

This design is to adopt to connect in the circular arc to make gear engagement; Adopt the slide to implement the gearshift function. under both effects, finish smooth gear change.

Embodiment:

Shown in Figure 10 as Fig. 1 Fig. 2 Fig. 3 Fig. 8 Fig. 9, the radian of arc 1 and arc 2 is two 45 degree and parallel arc, arc 3 is two arcs that curvature is identical and parallel with arc 4, axle 10 is parallel with axle 11, axle 11 is vertical with slideway 12, and slideway 12 is parallel with axle 9, and coaster 13 is made up of slideway 19 and slide block 21, axle 11 be preced with mutually with slideway 19, and spools 11 can horizontally slip in slideway 19; Slideway 20 is preced with mutually with slide block 21 and is connected, and axle 11 horizontally slips in slideway 20, and coaster 21 can slide up and down in track 12; Coaster 13 is when sliding like this, and when driving axle 11 gears 5 and gear 6 slips, sliding gear 5 and sliding gear 6 remain engagement with fixed gear 7 and fixed gear 8.

Shown in Figure 12 as Fig. 6 Fig. 7 Figure 11, power is by axle 10 inputs and driven gear 7 rotations, and gear 7 and gear 5 engagements and driven gear 5 rotation .16 are the arc tooth above the gear 7; 17 is the arc tooth above the gear 5; Arc tooth 16 and arc tooth 17 are meshed, be that arc 1 and arc 4 are meshed, under the acting in conjunction of stressed size and arc 1 and arc 22 curvature, arc 22 and arc tooth 16 can move along the track of arc 1 and arc 18 and change tooth radius automatically, thereby reach the purpose that changes rotating speed, power is transferred to gear 6. clockwise by axle 11 afterwards

Shown in Figure 12 as Fig. 4 Fig. 5 Figure 11, power is by axle 11 inputs and driven gear 6 rotations, and 14 is the arc tooth above 6; 17 is the camber tooth above 8; Arc tooth 14 and arc tooth 17 are meshed, be that gear 6 and gear 8 are meshed, under the acting in conjunction of stressed size and arc 2 and arc 15 curvature, arc tooth 17 and arc tooth 14 can move automatic change tooth radius along the track of arc 2 and arc 15, thereby reach the purpose that changes rotating speed., power is exported counterclockwise by axle 9 afterwards.

Comprehensive above-mentioned shown in Figure 10 as Fig. 1 Fig. 9, power is turned clockwise by stationary axle 10 clockwise input tape moving gears 7, gear 7 driven gears 5 turn clockwise, under the effect of the outputting power size of exporting stationary axle 9, arc 2 is slided along arc 3, arc 4 slides along arc 1, and being slided by contact points changes tooth radius and change rotating speed; Because arc 4 and arc 2 be when sliding, because axle 11 can only horizontally slip in slideway 19, and coaster 13 can only sliding up and down in track 12, the displacement that cooperates sliding gear to produce by both; Move on two 45 degree of gear 7 and gear 6 and parallel arc 1 and arc 2 by gear 5 and gear 3 like this. and change the engagement cut point of gear 5 and gear 8 and gear 7 and gear 6, reach the cutting radius that changes gear, and realization changes the purpose of rotating speed. last power is finished speed change by axle 9 outputs.
