How To Maintain Roller Chain

Before a car with a rear dial dials the chain to the state of the smallest wheel pair and the smallest wheel, the Roller Chain is looser and easier to operate.

After the chain is cleaned and lubricated, slowly turn the chainwheel. The chain links that come out of the rear dial should be able to be straightened. If some chain links still maintain a certain angle, it means that it does not move smoothly. It is a knot and should be taken. Adjustment. It is found that the damaged link must be replaced in time. The manufacturer of Roller Chain recommends strictly distinguishing three kinds of pins and using connecting pins. Pay attention to the straightness when using the chain, so that it is not easy to distort the thimble. Careful use of tools can not only protect the tools, but also achieve good results. Otherwise, the tools are easily damaged, and the damaged tools are more likely to damage the parts, which is a vicious circle.

Roller Chain Is Lightweight

 

Roller Chain advantages:
1. The roller chain effectively transmits power
Because it will not slip. The speed ratio is fixed and the absolute speed ratio.

2. Roller chain efficiency 98%
Under good lubrication, the efficiency of any load is quite good. This efficiency can be maintained throughout the life limit.

3. Universality of roller chain
It can still operate effectively in harsh environments such as dirt, oil, and gas mixture. A single power source can drive multi-axis output at the same time, and the speed can be adjusted by the ratchet gear.

4. Ability of roller chain to absorb vibration
The chain itself is flexible, and when the oil film is stored in each part, it can protect the shaft and motor from impact force and strain.

5. Light weight and small space
The width is narrow, it can be installed in a very small space, and the unit takes less space to transmit horsepower.

6. Durable roller chain
Because the load is shared by many teeth on the ratchet gear, each single gear has a small force to ensure life.

What Are The Pitches Of The Roller Chain

 

Roller Chain metal mesh belts have a variety of specifications. Depending on the volume of the customer's product and the weight of the conveyor, the appropriate chain pitch and distance between strings can be selected. The pitch of the conveyor chain used by the conveyor belt is generally 25.4, 31.75, 38.1, 50.8, 63.5, 76.2, 101.6mm, etc., are all special-purpose chains for the transportation of double-end large balls. The materials are carbon steel and stainless steel. If used in harsh environments such as high temperature and corrosion resistance, you must choose 201, 304, 316 and other materials according to requirements. .

Because the metal conveyor belt is a customized product, customers must carefully measure the specific data of the old product when replacing the new conveyor belt to ensure the practicability of the new mesh belt. There are also many customers who have not used the metal conveyor belt. I do n’t know anything about it. At this time, I need to communicate with the sales staff carefully, make clear to the sales staff their own ideas and the size of the conveyed product, and listen to the sales staff ’s suggestions for reference.

The chain mesh belt and the chain plate mesh belt are driven by the chain on both sides, so you need to know the pitch and material of the chain. The B-shaped mesh belt and the Great Wall mesh belt are directly driven by the chain wheel. The data required for the chain mesh belt includes the mesh pitch, pitch, wire diameter, string diameter, string spacing, chain pitch, material, total width, etc. The data required for the chain mesh belt includes pitch, plate thickness, string The shaft diameter, material, width, etc., because each chain pitch of the chain plate mesh belt needs a string of shafts, so the chain plate pitch and the chain pitch are the same. The relevant data of the Great Wall mesh belt (horseshoe chain) mainly include data such as material, plate thickness, plate width, string diameter, string spacing, upper mouth width and lower mouth width.

Precautions For Lubricating Roller Chain

1.Lubricant flow

Each hinge of the hzqjchain Roller Chain is a radial bearing, so it must be sufficiently and effectively lubricated to obtain the longest service life. In addition to being fully lubricated, it can also reduce the wear on the sound of pins and sleeves. It can also place sprocket and sprocket smoothly, slow down the impact of rollers and sprocket, and dissipate heat, and remove debris and foreign matter . . And prevent rust.

Before the chain engages with the sprocket, lubricate the upper part of the chain link plate. Gravity and centrifugal forces cause lubricant to flow to the pins and sleeve surfaces that need lubrication. Lubricants on the edges of the chain plates also provide lubrication for the pin and sleeve surfaces.

2. Lubricant characteristics:

Roller chain transmission lubricants should have the following characteristics:

A. Low enough viscosity to allow the lubricant to penetrate the surface to be lubricated;

B, can maintain sufficient lubricating film viscosity or add appropriate additives under normal bearing pressure;

C, clean and free of corrosive substances;

D. Under normal working conditions, it has the ability to maintain lubrication quality. Generally, high quality lubricants extracted from petroleum and free of detergents meet these requirements. Detergents are usually not needed, but it is best to add additives that prevent foaming, rusting and increase the strength of the oil film.

Advantages Of Roller Chain Using Uhmwpe Board

 


Ultra-high molecular weight polyethylene shaped parts, ultra-high molecular weight polyethylene bushings, linear guides for food machinery and equipment, vacuum tank washing tank panels, sliders for ultra-high molecular weight polyethylene food machinery, ultra-high molecular weight polyethylene wear bars, Molecular weight polyethylene shaped slider, UHMW polyethylene baffle seat, UHMW polyethylene bridge rail pad.
Therefore, Roller Chain guide rails use ultra-high molecular weight polyethylene boards. Let's take a look at its characteristics:

1. The ultra-high molecular weight polyethylene board has the highest wear resistance of plastics, and the larger the molecular weight, the higher the wear resistance and impact resistance of the material;
2. The impact strength of ultra-high molecular weight polyethylene board is the highest value among existing plastics. Even at 70 ° C, the impact strength is still quite high;
3.Self-lubricating;
4. Ultra-high molecular weight polyethylene board has extremely low water absorption. Therefore, its physical and mechanical properties have nothing to do with the environmental humidity factors in the working conditions used;
5. The ultra-high molecular weight polyethylene board is chemically stable, and can withstand the corrosion of various corrosion-resistant media such as acids, alkalis, salts and organic solvents within a certain temperature and concentration range;
6. Ultra-high molecular weight polyethylene board is odorless, non-toxic, odorless, has no corrosion resistance, and has physiological circulation and physiological adaptability.
7, non-adhesive;
8. When the molecular weight of high-density polyethylene exceeds 500,000, the embrittlement temperature decreases to 140 ° C. Ultra-high molecular weight polyethylene can even be used under the action of liquid nitrogen, and its use temperature can reach below 269 ° C.

Hzqjchain Industrial Chain Manufacturers Share Cleaning Methods For Chains

 

hzqjchain Industrial Chain manufacturer introduces the inspection method of the chain:

1.The chain is washed before measuring

2. Enclose the EK chain to be tested on two sprockets, and the upper and lower sides of the chain to be tested should be supported

3. The chain before measurement should stay for 1min under the state of one third of the tensile load

4. During the measurement, apply the specified measurement load on the chain to tension the upper and lower chains. The chain and the sprocket should ensure normal meshing.

5. Measure the center distance between the two sprockets.

Measuring chain elongation:

1.In order to remove the clearance of the entire chain, it is necessary to measure under a state of pulling tension on the chain

2.When measuring, in order to minimize the error, measure at the place of 6-10 (link)

3. Measure the inner L1 and outer L2 dimensions between the rollers of the number of knots to determine the judgment size L = (L1 + L2) / 2

4. Find the chain elongation length. This value is compared with the limit value of the chain elongation used in the previous item.
