Abstract
The invention discloses a gear transmission system for tongman skill training in teaching. The gear transmission system comprises two parallel wall boards, wherein three cylindrical spur gears with different diameters are mounted between the two wall boards, and each two of the three cylindrical spur gears are engaged mutually; a trapezoidal plate is arranged at one end of the two wall boards, and a cross plate is arranged at the other end; and the cylindrical spur gears, the trapezoidal plate and the cross plate form a movable fit with the two wall boards. The gear transmission system disclosed by the invention can be used as a teaching aid for students to simulate and machine, and can be used for training the hole member matching skills of the students so as to help the students understand the precision requirement for axial holes of gears and intuitively learn of the moving process of gear transmission and the speed-ratio relationship between gear pairs as well as the method for changing the rotation direction of gears in the gear transmission system.
Description
Technical field
The present invention relates to a kind of pincers worker skill training gear train assembly that is used to impart knowledge to students.
Background technology
Usually the processing of the pincers in mechanical major skill training is through letting the student adopt the concavo-convex pattern plate that matches of method processing and fabricating of sawing and filing to implement.For letting the student well grasp filing, size Control technical ability, often to practise repeatedly.Such training is more uninteresting to the student.Cause learning interest not high thus, it is slower that technical ability improves speed.
Summary of the invention
The purpose of this invention is to provide a kind of pincers worker skill training gear train assembly that is used to impart knowledge to students; To change the method for student's skill training, let the student pass through training and grasp more knowledge, make training no longer uninteresting simultaneously; Motivate students' interest in learning, improve results of learning.
For realizing above-mentioned purpose, the present invention adopts following technical scheme:
A kind of pincers worker skill training gear train assembly that is used to impart knowledge to students; Comprise two blocks of parallel wallboards; Said wallboard is that certain thickness rectangular steel plates is arranged, be useful on it mounting teeth wheel shaft circular hole, be used for dovetail groove that matches with trapezoidal plate and the rectangular opening that matches with four-bladed vane.The spur gear wheel of three different-diameters is installed between two blocks of wallboards, and an end of two blocks of wallboards is equipped with trapezoidal plate, and the other end is equipped with four-bladed vane.
Said trapezoidal plate is for there being certain thickness steel plate, and trapezoidal cross-section is made into movingly with dovetail groove on the wallboard mutually.
Said four-bladed vane is for there being certain thickness steel plate, and the flange at its two ends is made into movingly with rectangular opening on the wallboard mutually.
Said three spur gear wheel two ends have footstalk, and the circular hole on footstalk diameter and the wallboard matches and synthesizes movingly, and is installed in the corresponding circle hole of wallboard, and three spur gear wheels are meshed in twos.
Gear train assembly of the present invention can be used as teaching aid, supplies the student to imitate processing, has following beneficial effect:
(1) wallboard of the present invention, trapezoidal plate plate and four-bladed vane are that certain thickness steel plate is arranged, the technical ability but the hole part of its processing training of students matches;
(2) be used between the circular hole of mounting teeth wheel footstalk the pitch-row requirement being arranged on its deadlight, it will influence the gear meshing relation after producing error, and the student is through the accuracy requirement of processing understanding to the gear axis hole;
(3) this gear train assembly can supply the student to understand the speed ratio relation of gear-driven motion process and gear pair and the method that in the gear rotation system, changes the gear rotation direction intuitively.Pincers worker skill training with the student combines with mechanical principle knowledge thus, can improve students'interest in learning, improves learning efficiency.Fabricating quality directly influences the motion smoothing property of gear drive simultaneously, and the student analyzes the fabricating quality of oneself, and understands the requirement of the size and the form and position tolerance of machine-building thus through observing the motion of gear pair.
(4) gear drive described in the present invention is simple in structure, and material is economized, and has practiced thrift manufacturing cost greatly; Be fit to let every student independently make and train.

Embodiment
Below in conjunction with specific embodiment the present invention is set forth in detail.
Like Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, a kind of gear train assembly that is used for the pincers worker skill training, it comprises wallboard 2 (2), trapezoidal plate 1, four-bladed vane 6, big column spur gear 4, middle spur gear wheel 3 and small column spur gear 5.
The rectangular opening that supplies to install large, medium and small spur gear wheel circular hole of using and the dovetail groove of locating trapezoidal plate 1, location four-bladed vane 6 is arranged on the said wallboard 2;
Dovetail groove on the transversal section of said trapezoidal plate 1 and the wallboard 2 matches, and inserts in wherein.
Rectangular opening on the flange end face of said four-bladed vane 6 and the wallboard 2 matches, and inserts in wherein.
Said wallboard 2 is formed back-shaped framework with trapezoidal plate 1 and four-bladed vane 6.
There is the cylinder footstalk of location usefulness at said large, medium and small spur gear wheel two ends, and circular hole matches on its diameter and the wallboard 2, for movingly.
Said large, medium and small spur gear wheel is installed between two blocks of wallboards 2, and two twenty percent meshing relations.
Rotate any spur gear wheel, then two spur gear wheels rotate thereupon in addition, demonstrate out the kinematic relation of gear train.The student can therefrom understand the drive characteristic of gear train, and turning to of two gears is different, increases a gear therein as importing identical with turning to of output gear need, and its number of teeth does not influence transmission speed ratio.Therefrom also can recognize the ratio of gear relation of gear pair.
In reality is given a lesson process, let the student be simulated object with this gear train assembly, make wallboard and trapezoidal plate, four-bladed vane with the mode of pincers processing, it is the requirement of the pincers intermediate technical ability of processing that the form fit between them is made.Spur gear wheel is installed then, the crudy of check wallboard and trapezoidal plate, four-bladed vane.If machining precision is undesirable, gear train then can not be moved smoothly.The student can understand the reason that dimensional accuracy and morpheme in the part processing require thus, understands the kinetic characteristic of gear drive simultaneously.
