Entrance to the territory of a private house is usually blocked by a gate. They can have a different design, but one of the most convenient are retractable devices. They have many advantages, among which space savings should be highlighted. They are good because the system can be supplemented with an electric motor. But if you want to save money, you can open and close the sash manually.
Why choose a retractable design?
If the system is made correctly, it can withstand more than 50,000 opening and closing cycles. But before starting work, you should pay attention to one more plus, which is the free choice of material for sheathing the structure. It can be polycarbonate, profiled flooring and even wood. As one ofthe components of such gates are rollers, which you can make yourself.
What is important to consider before starting work?
Before you make roller doors, you should know that they are installed on the foundation. In order to achieve a good result, you should create a powerful base, on which a considerable weight will exert pressure. The rollers you created will move along the guide beam. Two supports should be used for secure fixation.
Which method of connecting parts to choose?
The structure must have sufficient strength, for this welding should be used. Stands and trolleys will move along the beam. The upper part will be located on the lower part of the gate, which allows for easy movement of the structure from side to side. If you wish, you can add an automatic drive to the system, which will simplify the operation process.
Description
The roller carriage, which is also called rollers, is one of the important parts in the system. In importance, only a guide rail can be compared with it. These components are responsible for the movement of the web. A sliding system usually uses a pair of rollers. It depends on how durable and high quality the bearings, rollers, as well as the bases of the carriages, whether the gate will last a decade or break in the first months of operation.
Having considered the description of rollers for rollinggate, with your own hands you can do them yourself. They consist of:
- axes;
- grounds;
- clips.
Additional Features
Bearings are pressed in. When buying such a device, you should pay attention to the fact that the carriage is made of high-quality and durable metal. It must have an even base. You can make the design of rollers for sliding gates with your own hands. However, they must be made from high-quality and durable material.
The rollers should move well along the axes, and there should be enough grease in the bearings. The rollers must work properly in winter and summer. They should not have a strong backlash. A roller carriage, if it is of good quality, should last about 20 years.
Production of rollers
If you want to make rollers for sliding gates with your own hands, you should prepare some components, among them:
- end roller;
- special rail;
- stubs;
- roller bearings;
- catcher.
Each of these elements has its purpose. However, only joint work will ensure the normal functioning of the system. During the design process, special attention is paid to the guide rail, which must have sufficient rigidity. If this part is not reliable enough, in the process of using it, the element will straighten up and the system will fail.
Work on the rail andbearings
When making rollers for sliding gates with your own hands, you should make a steel rail. Its thickness should be 3.6 mm minimum. Roller carriages will hold the mass of the structure, so when creating rollers, special attention should be paid to them. Good strong bearings will be needed, otherwise the sash will move with a creak, moreover, the rollers will collapse quite soon from such an impact. There should be no backlash during assembly and fixing of elements. Otherwise, the system will quickly fail.
Working on the top mount and bottom catcher
Reinforced bearings should be used for longer life. The upper rollers will be responsible for fastening the sash from above. They are made from rubber. The plastic will harm the paint. The thickness of the steel here should be 4 mm.
When making rollers for sliding gates with your own hands, you must remember that the end roller and the lower catcher will work together. The main function of the first is the unloading of the main rollers. The catcher must be made in such a way that the trailer fits into it. At the very end, plugs are installed. Their task is to protect the guide from snow and water.
Detailed description of the manufacture. Second option
Carts and roller carriages will take the load from the moving sash. After that, it is transferred to the foundation. Thanks to the caretthe profile with the frame will move along the opening. Each carriage should have 8 rollers, which can be polymer or metal. By purchasing factory carriages, you become the owner of a node, the quality of which is much higher than a home-made one. However, if you make rollers for sliding gates with your own hands, and do it right, they can last quite a long time.
For work, you can borrow bearings from the generator of the Zhiguli car. The inner diameter of the bearings can be equal to the limit from 14 to 40 mm. It must fit in the pipe and move freely along it. For the axes of the carriages, you can use M18 studs, which are cut into pieces of the desired length. You will also need an 8 mm iron plate for the base of the guide roller carriages for sliding gates. With your own hands, you can cope with the task if you use thick metal. Thin material will not withstand the mass of the structure and simply bend. If the iron of the required thickness was not at hand, you can make double plates by connecting them together.
Metal plate
The manufacturing process is quite simple. On metal plates, it is necessary to make markings and cut off the excess with an angle grinder. Then holes are drilled to mount the bearings. If the metal is rather thin, the plates must be welded together and the seams cleaned. The diameter of the holes must be equal to the diameter of the axle. In the case described, this value is 18 mm. Coolant oil should be used when drilling to prevent overheating of the metal.
On the nextstage, you can try on the axle holes, cutting them to the required length. Washers are put on the axles, followed by bearings. All this is tightly screwed on. The bearings are packed with grease until the base is welded.
Alternative roller making
If you want to make support rollers for sliding gates with your own hands, you can place them on the channel at a greater distance from each other. So you can reduce the shoulder of the sash and reduce the load on the node. For the manufacture of the support, 10 mm steel should be used. There should be 8 bearings per support and axles for bearings. It is better not to use cheap Chinese ones, since their service life is short. It is better to purchase more expensive ones, the purchase will be justified.
The dimensions of the bearings should be determined by the cross section of the pipe. The pipe will act as a guide rail. Before making rollers for sliding gates with your own hands, you will need to purchase bearings. In this case, it is important to pay attention to the protection of the ball mechanism, which is called anther. It can be metal-rubber or metal. It is better to stop at the first option, since the product will be in contact with negative factors, and the metal will rust, becoming unsuitable for further use.
After reviewing the photo of rollers for sliding gates, you will have to make them with your own hands and carry out anti-corrosion protection. This need is due to the fact that the nodes are constantly in contact with precipitation. Self-galvanizing is unlikely to be carried out, so painting and priming must be done in several layers. This will become one hundred percent protection, however, only for a while.
When purchasing roller bearings, you can choose a model with bearing cages made of metal or polymer. It is better to purchase a product with metal clips, since the operation of polymers requires compliance with a temperature range ranging from - 20 to + 50 ˚С. Otherwise, the polymers will start to lose their shape and break.
After reading the detailed description of rollers for sliding gates, you can make them yourself with your own hands. In order to slow down the wear of the assembly and distribute the load, the upper part must be made movable. This applies to supports. In this case, the rollers in the rail will tilt towards the movement of the sash. It is also important to take care of protection from moisture. The factory poles are galvanized so they can come into contact with water without being damaged.
After purchasing the roller bearings, you can install them with or without adjusting plates. Otherwise, installation is carried out on a concreted channel. Their base is seized by welding, after which you can check the progress of the gate. If the movement turned out to be difficult, the welding is cut off, and the supports are reinstalled. After that, they should be welded and checked for ease of movement. The described manipulations are repeated until the gate opens and closes withoutefforts.
After reading a detailed description of the manufacture of rollers for sliding gates, you can make this knot with your own hands. By supplementing it with an adjustment mechanism, you will make the installation process easier and faster. To do this, it is necessary to weld plates to the channel by installing roller bearings on top. In order to carry out the adjustment, it is necessary to rotate the nuts on the studs of the adjusting plates. It is important to provide a gap between the guide rails and the rollers of the supports, which should be 2 mm maximum. Otherwise, the lower free corner of the sash will dive when closing, not falling on the lower shelf of the catchers. In this case, the sash will not close.
