Comprehensive experimental description of gear transmission strength design

Comprehensive experimental description of gear transmission strength design,Microcomputer line protection system experimental device

The gear transmission intensity design is one of the important chapters in the "Mechanical Design" course. The experimental device has not been comprehensively tested and analyzed for the bending strength and contact intensity of gear transmission at home and abroad. A blank provides an indispensable experimental equipment for mechanical students to deeply understand the strength of gear transmission strength design.

Experimental project content:

1. Understanding, observation and analysis of the working principle of the mechanical transmission ch--n and the structure of the component structure, and disassemble the experiment.

2. The understanding of the electrical signal control and transmission ch--n of the experimental desk, observation and analysis of the principles of work.

3. Operation experiment:

(1) Calculation calculation of the tooth root bending intensity of str--ght tooth and oblique tooth cylindrical gear transmission;

(2) The stress testing and comparative analysis of the stress test and comparative analysis of the stress test and comparative analysis of the str--ght tooth cylindrical gear and the oblique cylindrical gear at the same center;

(3) Stress testing and comparative analysis of stress testing and comparative analysis of different loads and equivalent loads at the same speed;

(4) Stress test and comparative analysis when the load is equal to different speeds;

(5) Battle and force analysis of gear transmission ch--n.

I. Overview

This device adopts a microcomputer line protection device widely used in modern power engineering, equipped with modules such as power supply, two sections of transmission lines, intestines, and intelligent fault settings. This device m--nly completes the tr--ning of the characteristics of the protection of the characteristics of the protection device, the wiring, the settings, and the operation. It can be used for tr--ning in the power industry, and it can also be used for the assessment of the tr--ning of students related to high school and technical technical schools.

Smart fault settings and large screen LCD questions:

Operating unit

Operating unit circuit board (integrated with display), keyboard.

The operating unit adopts multiple protection design; dual power supply DC 12V input; 128x64LCD display; 8th road switch to the alarm input, *** more 48 relay control; the operating unit can not be connected to the offline assessment; the score can be automatically rated; Screen prompts.

There are m--nly the following operating functions:

Student entrance: Students can be used when the students are lifted, and they can inquire about the rem--ning time of the assessment.

Teacher entrance: Set up faults, to remove all f--lures, set the assessment time, modify the login password, and set the device number. Teachers need to log in to the password.

Score query: query the current scoring of students.

Learning number query: Query the teacher set by the teacher through the computer.

Equipment number query: query the device address of this machine, each operating unit has a ** device address.

The assessment time starts: After the teacher setting the assessment time, the assessment starts to count the countdown.
