Below in conjunction with accompanying drawing, the utility model is described in further detail:
With reference to accompanying drawing: the milling machine porose disc formula selector gear instruments used for education in the present embodiment, comprise support baseboard 1, on support baseboard 1, be fixed with two blocks of wallboards 2 perpendicular to support baseboard 1, on the top of two blocks of wallboards 2, be connected with the worktable 3 for demonstrating speed changing effect, on worktable 3, be connected with the leading screw 4 for driving worktable 3 to move left and right, leading screw 4 is connected to the below of worktable 3 by feed screw nut 4-1, leading screw 4 is arranged between two blocks of wallboards 2, the first gear 5 is installed on leading screw 4, the below of leading screw 4 is provided with and is arranged on two axles 1 between wallboard 2, the second gear 7 is installed on axle 1, the second gear 7 engages with the first gear 5, on axle 1, be provided with three with the meshing gear 8 of the second gear 7 coaxial rotatings, the diameter of each meshing gear 8 is all not identical, the below of axle 1 is provided with and is arranged on two axles 29 between wallboard 2, three shifting slide gears 10 that can engage with single meshing gear 8 on axle 1 are installed on axle 29, on three shifting slide gears 10, be connected with the shift fork 11 moving for stirring three shifting slide gears 10 on axle 29, on axle 29, be connected with the motor 12 rotating for driving shaft 29, the below of axle 29 is provided with rack shaft 1 and rack shaft 2 14, rack shaft 1 and rack shaft 2 14 are installed between two blocks of wallboards 2, shift fork 11 is connected on rack shaft 1, between rack shaft 1 and rack shaft 2 14, be connected with the 3rd gear 15, the 3rd gear 15 is arranged on wallboard 2, the outer end of rack shaft 1 and rack shaft 2 14 is all stairstepping setting, the outer end of rack shaft 1 and rack shaft 2 14 is connected with porose disc 16, on porose disc 16, be distributed with one group of size and rack shaft 1, the through hole 17 that every section of ladder of the stepped appearance outer end of rack shaft 2 14 mates respectively, the big or small through hole 17 that is connected rack shaft 2 14 with porose disc 16 of through hole 17 that porose disc 16 connects rack shaft 1 varies in size.
Motor 12 is by Timing Belt 18 coupling shafts 29.
On porose disc 16, be connected with the rotating disk 19 for driving porose disc 16 to rotate, rotating disk 19 connects porose disc 16 by rotating shaft 20.
Rotating disk 19 is arranged on support baseboard 1 by rotary disk basement 21, and rotating shaft 20 is connected in rotary disk basement 21, and rotating disk 19 is connected in rotating shaft 20.
Axle 1, axle 29 are all provided with bearing 22 with the junction of wallboard 2.
The stepped appearance outer end of rack shaft 1 and rack shaft 2 14 is divided into three sections, diameter increases from outside to inside successively, in the time that the first paragraph of the stepped appearance outer end of rack shaft 1 penetrates the diameter through hole 17 corresponding with this section of stepped appearance outer end, corresponding through hole 17 through hole 17 corresponding with the stepped appearance outer end of rack shaft 1 in stepped appearance outer end of rack shaft 2 14 varies in size, therefore, porose disc 16 must need to keep balance by promoting rack shaft 1 or rack shaft 2 14, therefore, in the time that porose disc 16 promotes rack shaft 1, or promote rack shaft rack shaft at one 13 o'clock at porose disc 16, because rack shaft 1 and rack shaft 2 14 engage by the 3rd gear 15, rack shaft 2 14 moves and will inevitably drive rack shaft 1 to move like this, therefore, rack shaft 1 moves and can drive shift fork 11 to move, thereby three shifting slide gears 10 are moved, three shifting slide gears 10 move from different meshing gear 8 and coordinate the change that realizes rotating speed.
The principle of the utility model embodiment is: first porose disc 16 is pulled and left from rack shaft 1 and rack shaft 2 14, again porose disc 16 is rotated to certain angle, when porose disc 16 rotates after certain angle, through hole 17 corresponding with the second segment step size of rack shaft 2 14 stepped appearance outer ends on porose disc 16 is aimed at, again porose disc 16 is pushed in rack shaft 1 and rack shaft 2 14, when the second segment ladder of rack shaft 2 14 stepped appearance outer ends and porose disc 16 against time, the big or small through hole 17 that is connected rack shaft 2 14 with porose disc 16 of through hole 17 that connects rack shaft 1 due to porose disc 16 varies in size, like this in the time that porose disc 16 is resisted against on rack shaft 2 14, thereby porose disc 16 promotes rack shaft 1 to make porose disc 16 keep balance, the 3rd gear 15 is for realizing the mutual movement between rack shaft 1 and rack shaft 2 14, rack shaft 1 is pushed rear drive shift fork 11 and moves like this, stir three shifting slide gears 10 and move on axle 29 thereby shift fork 11 moves, thereby three shifting slide gears 10 are engaged from the different meshing gears 8 on axle 1, thereby change ratio of gear, thereby change the rotating speed of axle 1, the change of axle one 6 rotating speeds makes the second gear on axle 1 turn 7 speed changes like this, after changing, the second gear 7 rotating speeds drive the change of the first gear 5 rotating speeds, the change of the first gear 5 rotating speeds changes the speed of leading screw 4, because worktable 3 is moved and moved by leading screw 4, the change of leading screw 4 speed changes the translational speed of worktable 3 like this, thereby be intuitively clear that the variation of speed, porose disc 16 and rack shaft 2 14 different phase positions, stepped appearance outer end are corresponding so just can obtain different speed, thereby realize the effect of speed change.
Thereby motor 12 starts and drives Timing Belt 18 transmissions, thus Timing Belt 18 transmission driving shafts 29 rotations, thereby it is mobile to make worktable 3 produce by transmission, make student can clear view to the speed of movable workbench, easy to use.
Because rotating disk 19 links together by rotating shaft 20 and porose disc 16; so just can realize by rotating rotating disk 19 rotation of porose disc 16; easy to use; rotary disk basement 21 is for installing rotating shaft 20 and rotating disk 19; easy to use; bearing 22, for the protection of axle 1 and axle 29, reduces the wearing and tearing of axle 1 and axle 29, increases the serviceable life of instruments used for education.
The feature of the present embodiment is: can intuitively clearly observe the variation of speed by the variation of worktable 3 translational speeds, can clearly express the mechanical principle of milling machine porose disc formula selector gear, make teacher's teaching simpler, lively and vivid, can make student's easy to understand, can strengthen the ability of student's perceptual knowledge directly perceived, can make teacher's guiding student observe, analyze, think deeply and ask a question, and can therefrom learn the method for dealing with problems, can motivate students' interest in learning, can improve student's learning efficiency, result of use is good, be beneficial to popularization.
Although the utility model illustrates and describes by reference to preferred embodiment,, those skilled in the art should understand, and in the scope of claims, can do the various variation in form and details.
