Abstract
The utility model discloses a gear drive system of locksmith skill training for teaching and the gear drive system comprises two parallel wallboards. Three cylinder spur gears with different diameter are arranged between the two wallboards and are engaged with each other. A trapezoidal plate is mounted on one end of the two wallboards and a cross plate is disposed on the other end. The cylinder spur gears, the trapezoidal plate and the cross plate are matched with the two wallboards in a movable manner. The gear drive system provided by the utility model can be used as a teaching appliance and used for students simulating and processing. The students' hole-piece matching skill can be trained. The students can understand a precision requirement to a gear shaft hole and visually understand a motion process of gear drive and a speed ratio relation of a gear pair and a method for changing a gear rotation direction in the gear rotation system.
Description
Technical field
The utility model relates to a kind of bench skill training gear train assembly for teaching.
Background technology
Usually the processing of the pincers in mechanical major skill training is by allowing the student adopt the concavo-convex section mould plate that matches of method processing and fabricating of sawing and filing to implement.For allowing the student well grasp filing, size Control technical ability, often to repeatedly practise.Such training is more uninteresting to the student.Cause thus learning interest not high, it is slower that technical ability improves speed.
Summary of the invention
The purpose of this utility model provides a kind of bench skill training gear train assembly for teaching, to change the method for students' skill training, allow the student pass through training and grasp more knowledge, make simultaneously training no longer uninteresting, motivate students' interest in learning, improve results of learning.
For achieving the above object, the utility model adopts following technical scheme:
A kind of bench skill training gear train assembly for teaching, comprise two blocks of parallel wallboards, described wallboard is that certain thickness rectangular steel plates is arranged, be useful on it mounting teeth wheel shaft circular hole, be used for the 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.
Described trapezoidal plate is for there being certain thickness steel plate, and trapezoidal cross-section is made into movingly mutually with dovetail groove on the wallboard.
Described four-bladed vane is for there being certain thickness steel plate, and the flange at its two ends is made into movingly mutually with rectangular opening on the wallboard.
Described three spur gear wheel two ends are with 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 utility model can be used as teaching aid, imitates processing for the student, has following beneficial effect:
(1) wallboard of the present utility model, 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) between the circular hole for mounting teeth wheel footstalk the pitch-row requirement is arranged on its deadlight, will affect the meshing relation of gear after its generation error, the student is by the accuracy requirement of processing understanding to the gear axis hole;
(3) this gear train assembly can be understood intuitively for the student speed ratio relation of gear-driven motion process and gear pair, and the method that changes the gear rotation direction in the gear rotation system.Bench skill training with the student combines with mechanical principle knowledge thus, can improve student's learning interest, improves learning efficiency.Make simultaneously the motion smoothing that quality directly affects gear drive, the student analyzes the making quality of oneself, and understands thus the requirement of size and the form and position tolerance of machine-building by observing the motion of gear pair.
(4) gear drive described in the utility model is simple in structure, and material is economized, and has saved greatly manufacturing cost; Be fit to allow every student independently make and train.

Wherein, 1 is trapezoidal plate, and 2 is wallboard, and 3 is middle spur gear wheel, and 4 is the big column spur gear, and 5 is the small column spur gear, and 6 is four-bladed vane.
Embodiment
The utility model is elaborated below in conjunction with specific embodiment.
Such as Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, a kind of gear train assembly for bench skill training, it comprises wallboard 2(2 piece), trapezoidal plate 1, four-bladed vane 6, big column spur gear 4, middle spur gear wheel 3 and small column spur gear 5.
Have on the described wallboard 2 for the circular hole that large, medium and small spur gear wheel is installed and the dovetail groove of location trapezoidal plate 1, the rectangular opening of positioning cross plate 6;
Dovetail groove on the transversal section of described trapezoidal plate 1 and the wallboard 2 matches, and inserts in wherein.
Rectangular opening on the flange end face of described four-bladed vane 6 and the wallboard 2 matches, and inserts in wherein.
Described wallboard 2 forms back-shaped framework with trapezoidal plate 1 and four-bladed vane 6.
There is the cylinder footstalk of location usefulness at described large, medium and small spur gear wheel two ends, and circular hole matches on its diameter and the wallboard 2, for movingly.
Described large, medium and small spur gear wheel is installed between two blocks of wallboards 2, and two twenty percent meshing relations.
Rotate any one 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 therein a gear as inputting identical with turning to of output gear need, and its number of teeth does not affect transmission speed ratio.Therefrom also can recognize the ratio of gear relation of gear pair.
In the class process, allow the student take this gear train assembly as simulated object actually, 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.Then spur gear wheel is installed, 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 of dimensional accuracy and morpheme requirement in the part processing thus, understands simultaneously the kinetic characteristic of gear drive.
