Abstract
The utility model discloses a kind of contact ratio and overlap ratio page plate.Mechanical principle course is abstract, and mechanical principle mechanism Display Rack price is high, and Portable belt not.The utility model comprises transparent coating, top book frame, Ye Ban mechanism, base plate, active thumb wheel and driven thumb wheel; Top book frame and base plate are bonding, and initiatively all and base plate hinged, and initiatively thumb wheel meshes with driven thumb wheel for thumb wheel and driven thumb wheel; Initiatively a side of thumb wheel is exposed the side of Ye Ban mechanism; Ye Ban mechanism comprises registration driving gear, the first follower gear and the second follower gear; Registration driving gear, the first follower gear and the second follower gear are all and base plate hinged; Registration driving gear and driven thumb wheel are fixed, and the first follower gear and the second follower gear mesh with registration driving gear respectively; Transparent coating is bonded on the book frame of top.The utility model becomes the gear mechanism in mechanical principle course into stereoscopic mechanism, intuitively lively.
Description
Technical field
The utility model belongs to educational aid field, relates to textbook, is specifically related to a kind of contact ratio and overlap ratio page plate.
Background technology
Show by inquiry, it is too abstract that each large college student generally reacts mechanical principle course, and classroom indigestion causes achievement not increase.Although for this problem, most of industry science class colleges and universities have all been equipped with mechanical principle mechanism Display Rack, extracurriliar or visit while testing for students, be intended to serve better student and learn mechanical principle course well.Yet Display Rack exists two defects, and on the one hand, Display Rack is expensive, a Display Rack just needs fund up to ten thousand, and the mechanism of mechanical principle has a lot, has increased burden to the infusion of financial resources of school, mechanical principle course.On the other hand, Display Rack is bulky, cannot take the classroom use of attending class, and some school is even locked in laboratory by Display Rack, and student seldom has an opportunity really to touch mechanism, and the meaning of Display Rack is reduced.How to school, to reduce costs, and Neng Ba mechanism takes classroom to, for student, attend class, play good aided education, allow course become more vivid, allow student's study become a happy process, these problems have to be solved.Therefore, develop an operable stereoscopic mechanism book in this classroom, will on classroom, classroom, bring into play huge effect.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, a kind of contact ratio and overlap ratio page plate is provided, be applicable to the explanation of mechanical principle course contact ratio and overlap ratio, by stirring the gear of books side, gear mechanism is moved, demonstration is lively, to classroom, heighten the enjoyment, the intuitive that elevating gear principle knowledge Focal point and difficult point is lectured and interactive; By mechanism, demonstrate and add basic theoretical knowledge, contact ratio and overlap ratio is analyzed, designed, cultivate student's knowwhy application power, overcome stiff, the abstract problem of standard machinery principle books.
The utility model comprises transparent coating, top book frame, Ye Ban mechanism, base plate, active thumb wheel and driven thumb wheel; Described top book frame and base plate are bonding, and described Ye Ban mechanism, initiatively thumb wheel and driven thumb wheel are all arranged between top book frame and base plate, and all and base plate hinged, and initiatively thumb wheel meshes with driven thumb wheel for described active thumb wheel and driven thumb wheel; One side of described active thumb wheel is exposed the side of Ye Ban mechanism.Described Ye Ban mechanism comprises registration driving gear, the first follower gear and the second follower gear; Described registration driving gear, the first follower gear and the second follower gear are all and base plate hinged; The lower surface of described registration driving gear and the upper surface of driven thumb wheel are fixed, and the first follower gear and the second follower gear mesh with registration driving gear respectively.Described transparent coating is bonded on the book frame of top, is printed on knowledge piece of writing title, contact ratio and overlap ratio figure and registration computing formula on transparent coating; Described contact ratio and overlap ratio figure is arranged on directly over Ye Ban mechanism.
The beneficial effects of the utility model:
1, the utility model carries out physical object simulating by the gear mechanism in mechanical principle, and be integrated in page plate, by 3 D stereo mechanism, contact ratio and overlap ratio figure and knowledge point statement combination, abstract, the complicated knowledge point of script is transformed into three-dimensional movable stereoscopic mechanism, make knowledge point become more directly perceived lively, be convenient to promote student's learning interest, for mechanical principle course teaching, make teaching process lively, vivid.
2, the utility model compact, be convenient for carrying, be convenient to change, cost is low, is highly suitable on the course (as Machine Design, Graphing of Engineering) that needs to demonstrate mechanism on colleges and universities classroom and promotes, and has higher economic worth and application value.
3, the utility model is applicable to standardization production, and production cost is low, and using value is high.
Accompanying drawing explanation
Fig. 1 is stereographic map of the present utility model;
Fig. 2 is the schematic diagram of transparent coating in the utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As illustrated in fig. 1 and 2, a kind of contact ratio and overlap ratio page plate, comprises transparent coating 1, top book frame 2, Ye Ban mechanism 3, base plate 4, active thumb wheel 5 and driven thumb wheel 6; Top book frame 2 is bonding with base plate 4, and Ye Ban mechanism 3, active thumb wheel 5 and driven thumb wheel 6 are all arranged between top book frame 2 and base plate 4, and initiatively thumb wheel 5 and driven thumb wheel 6 are all hinged with base plate 4, and initiatively thumb wheel 5 and 6 engagements of driven thumb wheel; Initiatively a side of thumb wheel 5 is exposed the side of Ye Ban mechanism 3, and available hand is stirred initiatively thumb wheel 5, drives driven thumb wheel 6 motions, thus 3 motions of band moveable leaf plate mechanism.Ye Ban mechanism 3 comprises registration driving gear 3-1, the first follower gear 3-2 and the second follower gear 3-3; Registration driving gear 3-1, the first follower gear 3-2 and the second follower gear 3-3 are all hinged with base plate 4; The lower surface of registration driving gear 3-1 and the upper surface of driven thumb wheel 6 are fixed, and the first follower gear 3-2 and the second follower gear 3-3 mesh with registration driving gear 3-1 respectively.Transparent coating 1 is bonded on top book frame 2, is printed on knowledge piece of writing title 7, contact ratio and overlap ratio figure 8 and registration computing formula 9 on transparent coating 1; Contact ratio and overlap ratio figure 8 is arranged on directly over Ye Ban mechanism 3, helps teacher to explain the knowledge of contact ratio and overlap ratio.
The use of this contact ratio and overlap ratio page plate:
This contact ratio and overlap ratio page plate has carried out the analysis of physical object simulating and Key Points for the gear mechanism in mechanical principle; Student can stir initiatively thumb wheel 5 with hand, thereby the motion of gear mechanism and all critical learning in motion process are profoundly understood in 3 motions of band moveable leaf plate mechanism.
