It's the most common, and we have two parts, and I think these two parts are also helpful for all of us to improve and help.

What are the two most common parts of a drive chain? The common spraying practice must depend on him, the top part is different, and its name and function must be different.

In terms of transmission efficiency, the gear is the first and then the chain and finally the belt, and the chain is the last, the belt is the first, and the gear is second.

The most common rotating chain, generally speaking, is the middle of the two gears that drive the chain to rotate. One is active and the other is passive intelligence.

The most common transmission shaft, you want to know which two parts are used, you can check the relevant information on the Internet.

Features Compared to belt drive, chain drive has no elastic slip and slipAble to maintain accurate average gear ratios; The required tension is small, and the pressure acting on the shaft is also small, which can reduce the friction loss of the bearing; Compact structure; It can work under harsh environmental conditions such as high temperature and oil stains. Compared with gear drives, chain drives have lower manufacturing and installation accuracy requirements; When the center distance is large, its transmission structure is simple. The instantaneous chain speed and instantaneous transmission ratio are not constants, so the transmission smoothness is poor, and there is a certain impact and noise in the work.

The average transmission ratio of chain drive is accurate, the transmission efficiency is high, the distance between the shafts is adaptable, and it can be used in the environment with high temperature and high humidity; However, the chain drive can generally only be used as a parallel shaft transmission, and its instantaneous transmission ratio fluctuates, and the transmission noise is large. Since the chain links are rigid;

As a result, there is a polygon effect (i.e., non-uniformity of motion), which causes the instantaneous transmission ratio of the chain drive to change and cause additional dynamic loads and vibrations, which must be considered when selecting the chain drive parameters. Chain drives are widely used in transportation, agriculture, light industry, mining, petrochemical industry and machine tool industry.

Number of sprocket teeth. In order to improve the stability of the movement of the chain drive and reduce the dynamic load, it is better to have more teeth for small sprockets. However, the number of small sprocket teeth should not be too much, otherwise =i will be large, so that the chain drive will fail to skip teeth earlier.

After the chain works for a period of time, the wear makes the pin thinner, the sleeve and roller thinner, and the pitch of the chain is elongated under the action of tensile load f.

When the chain pitch becomes longer, the pitch D moves towards the top of the tooth when the chain winds around the sprocket. Generally, the number of chain links is even to avoid the use of adapters. In order to make the wear uniform and improve the life, the number of sprocket teeth should be co-qualitated with the number of chain links, and if the co-quality cannot be guaranteed, the common factor should be as small as possible.

Features: Advantages: No slippage.

Compact structure; The pressure on the shaft q is small.

High transmission efficiency = 98%.

It can be used in environments with high temperature and high humidity.

It can transmit long-distance transmission AMAX=8mm

Disadvantages: Can only be used for transmission between parallel shafts.

The instantaneous transmission ratio is not constant, and the transmission is not stable at high speed.

It is not suitable for application in transmissions with large load changes and rapid reversal.

There is noise and impact during transmission.

The manufacturing cost is higher than that of belt drive.

There are 4 components of the chain drive.

Chain drive is a common mechanical transmission method, which usually consists of chains, gears, sprockets, bearings, etc.

Chain: First of all, the chain is the core component of the chain drive, which is composed of a series of links, pins and jackets. The function of the chain is to transmit power to the gear or sprocket, which is compact and strong, and can adapt to the working environment of high load and high speed.

Gears: Secondly, gears are an important part of chain drives, which are made up of a series of gear teeth and hubs. The role of the gear is to convert the power transmitted from the chain into rotational force, and its structure is properly designed to achieve efficient energy transfer.

Sprockets: In addition, sprockets are also an important part of the chain, which is composed of a series of sprocket teeth and hubs. The function of the sprocket is to connect the chain to the gear, so that the gear can receive the power from the chain.

Bearings: In addition, the chain drive also needs the support of bearings, which can ensure smooth rotation between chains, gears and sprockets, while reducing friction and extending the service life of mechanical parts.

In short, chain drive is a complex mechanical transmission method, its components include chains, gears, sprockets, bearings, etc., their structure and design play a vital role in the efficiency and stability of chain drive.

How the chain drive works:

The chain drive is a meshing drive, and the average gear ratio is accurate. It is a mechanical transmission that uses the meshing of the chain and the sprocket teeth to transmit power and movement. The length of the chain is expressed in terms of the number of links.

Number of links: The number of links is best taken as an even number, so that when the chain is connected into a ring, the outer chain plate is connected with the inner chain plate, and the joint can be locked with a spring clip or cotter pin. If the number of links is odd, transition links are used.

When the chain is in tension, the transition link is also subjected to the bending load attached to the saturation, which should generally be avoided.

Sprocket: The sprocket shaft face is rounded on both sides of the tooth shape to facilitate the entry and exit of the chain link. Sprocket teeth should have sufficient contact strength and wear resistance, so the tooth surface is mostly heat treated.

Small sprockets have more meshing times than large sprockets, and the impact force is also greater, so the materials used should generally be better than large sprockets. Commonly used sprocket materials are carbon steel, gray cast iron, etc. Important sprockets can be made of alloy steel.

The transmission chain is divided into A series, and B series. The A series is in line with the American chain bent eggplant standard, and the B series is in line with the European chain standard, and there is not much difference between the two chains.

The specifications of the transmission chain are shown in the following table.

The chain drive is mainly composed of a sprocket and a chain mounted on the sprocket. The chain drive is the meshing of the hall mold through the meshing between the chain and the sprocket teeth to transmit the power of the orange, so the essence of the chain drive is meshing transmission.

There are two types of chain drives: roller chains and toothed chains.

Advantages of chain drive: the center distance varies widely, can work under harsh conditions, and has little force on the shaft and bearing. Chain drive advantages:

The center distance varies widely, and it can work under harsh conditions, with little force on the shaft and bearing. Disadvantages: The speed of the inter-mausoleum is unstable during operation, there is shock, vibration and noise, and the interference is poor and the precision is high.

The service life is about 2 to 3 times that of the belt drive.

The characteristics of the chain drive are as follows:

Compared with belt drive, chain drive has no elastic slip and slip, and can maintain an accurate average gear ratio; The required tension is small, and the pressure acting on the shaft is also small, which can reduce the friction loss of the bearing; It has a compact structure and can work under harsh environmental conditions such as high temperature and oil stains. Compared with gear transmission, the manufacturing and installation accuracy requirements of chain drive are lower, and its transmission structure is simple when the center distance is large.

1. Compared with gear transmission, it can transmit motion and power when the center of the two shafts is far apart;

2. Able to work under low-speed, heavy-load and high-temperature conditions and in the bad environment of dusty soil;

3. Compared with belt drive, it can ensure an accurate average transmission ratio, the transmission power is larger, and the force acting on the shaft and bearing is smaller;

4. The transmission efficiency is high, generally reachable;

5. After the chain of the chain is worn, the pitch becomes larger and causes the phenomenon of falling off;

6. The installation and maintenance requirements are high, and the sprocket material is generally structural steel.

Chain drive basic type:

According to different uses, chains can be divided into three categories: lifting chains, traction chains and transmission chains. The lifting chain is mainly used to lift heavy objects in lifting machinery, and its working speed v ; The traction chain is mainly used to move heavy objects in the chain conveyor, and its working speed is v 4m s; The transmission chain is used to transmit motion and power in general machinery, and the working speed is usually v 15m s.

There are two types of transmission chains: toothed chains and roller chains. The toothed chain is to use the specific tooth shape of the chain and the sprocket meshing to achieve transmission, the toothed chain transmission is stable, the noise is very small, so it is also called the silent chain transmission buried loss. The allowable working speed of the toothed chain can reach 40m s, but the manufacturing cost is high and the weight is large, so it is mostly used in high-speed or high-motion accuracy requirements.

There are two main types of chains used for power transmission: sleeve roller chain and toothed chain. The sleeve roller chain is composed of an inner plate, an outer plate, a sleeve, a pin, and a roller. The outer chain plate is fixed on the bearing pin, the inner plate is fixed on the sleeve, and the roller and the sleeve and the sleeve and the bearing pin can rotate relatively, so the meshing between the chain and the sprocket is mainly rolling friction.

The sleeve roller chain can be used in a single row or in multiple rows, and the combination of multiple rows can transmit large power.
