Course design: Chain conveyor drive, reducer 70

Why do you need to add engine oil?

Answer: engine oil, mechanical oil, is lubricating oil, function: 1, the formation of oil film in the gear meshing part, so that the meshing gear is not in direct contact, due to the theory of 2 gears meshing at one point, but, in practice, processing error and other factors, so that the 2 meshing gears have a sliding amount at the moment of meshing, if there is no oil film isolation, so that the metal is in direct contact, there will be serious wear, wear and tear, it will produce a lot of heat, the transmission efficiency is reduced, the heat generated will make the gear glued, pitting, etc., Cause the failure of the gear,,, by adding lubricating oil, produce an oil film on the gear, hinder the direct contact of the gear, and at the same time, the lubricating oil can take away the heat generated by the gear meshing, which has the effect of cooling, and will also wash away the wear and tear iron filings produced by the gear meshing, and play a cleaning role.

2.The principle of the reducer is mainly to reduce the speed and increase the output torque through gear meshing, of course, there are special planetary reducers, cycloid reducers, three-ring reducers, etc., you can search for it, a lot of information,,, as for the stepless speed regulator, it is to integrate a stepless speed regulation device in the reducer, mainly the friction disc type, and adjust the output speed by adjusting the contact area of the two parts of the friction plate.

3.The oil filler is generally at the highest point of the reducer, and some are breathable bolts that double as oil fillers, which are used for refueling after unscrewing the breathable plugs, and the oil fillers of the reducer are generally observation windows, and the oil fillers of other small geared motors have screw plugs, and the holes after unscrewing the screw plugs are used for refueling.

Help, I need my design topic too.

A worm reducer is designed for use on chain conveyors. Works smoothly and rotates in one direction. The term of work is 5 years. The allowable speed error of the traction chain is within 5%. The reducer is well ventilated. Mass production of reducers.

Traction chain pull f n 6000

Traction chain velocity v

The number of teeth of the traction chain sprocket z 12

Traction chain pitch p mm 100

Number of working shifts Double.

Help, help, help! Thank you!!! Send me an email thank you!! The sooner the better.

1 reducer assembly drawing (A3) 2 parts working drawings 1 design specification.

You send me an email, I'll send you a reference to the past, and you know that this is not a simple matter.

Mechanical design course design, the design method of the first-stage cylindrical gear reducer in the transmission device of the chain conveyor, first according to the determination of the load of the motor and the power of the reducer, then calculate the design of the reducer reduction ratio, and then refine the design of the transmission shaft and other details, and finally carry out the design of the assembly drawing.

See if this picture is like this, confirm your post, I will send you an email after receiving the best notification, the parameters may be different, dwg drawings can be referenced.

This graduation project is about the design of a fixed belt conveyor for mining. A brief overview of the preferred belt conveyor is given: then the selection principle and calculation method of the belt conveyor are analyzed; Then, according to these design criteria and calculation and selection methods, the selection design is carried out according to the requirements of the given parameters. Then, the main components of the selected conveyor were checked.

A normal belt conveyor consists of six main components: the transmission device, the tail and guide back device, the middle frame, the tensioning device, and the belt. Finally, the installation and maintenance of the conveyor are briefly explained.

At present, belt conveyors are developing in the direction of long distance, high speed and low friction, and the air cushion belt conveyor that has appeared in recent years is one of them. In terms of the design, manufacture and application of belt conveyors, there is still a big gap between China and foreign advanced levels, and there are many deficiencies in the process of designing and manufacturing belt conveyors in China.

The above information is from the "threesome design network" I just copied a part of it for you to show I hope it can help you He is quite complete You can go and see it Hehe.

1. Motor selection (low cost is best).

2 gear ratio distribution (i belt in 2-4 i tooth in 4-6) 3 belt drive design.

4. Gear design.

5. Shafting design.

6. Bearing design.

7. Standard parts design, 8. Lubrication.

Mechanical Design Course Design: Belt Conveyor Transmission Design With so much content, how can someone give you a good job for free and then send it back to you? If you want to pay for it, if you don't want to pay for it, you can collect the information yourself and do it yourself.

You go to the library and look for it, there are a lot of mechanical course design books with design content and diagrams.

I'll draw again, your school?
