Heavy-duty planetary Speed reduction gearbox assembly guide:
Proper installation, use and maintenance of heavy-duty planetary Speed reduction gearbox is an important part of ensuring the normal operation of mechanical equipment. Therefore, when installing a heavy-duty planetary Speed reduction gearbox, be sure to carefully assemble and use it in strict accordance with the following installation and use.
first step
Before installation, confirm whether the motor and heavy-duty planetary Speed reduction gearbox are intact, and strictly check whether the dimensions of the parts connected to the Speed reduction gearbox are matched. Here are the dimensions of the positioning boss of the motor, the input shaft and the groove of the Speed reduction gearbox, and the tolerances. .
Second step
Unscrew the screw on the outer dust-proof hole of the heavy-duty planetary Speed reduction gearbox flange, adjust the clamping ring of the PCS system so that the side holes are aligned with the dust-proof holes, and insert the hexagon socket into the hexagon. After that, remove the motor shaft key.
third step
Connect the motor to the heavy-duty planetary Speed reduction gearbox naturally. When connecting, it must be ensured that the output shaft of the heavy-duty planetary Speed reduction gearbox is concentric with the input shaft of the motor, and the outer flanges of the two are parallel. As the heart is inconsistent, it will cause the motor shaft to break or the Speed reduction gearbox gear to wear.
In addition, when installing a heavy-duty planetary Speed reduction gearbox, it is strictly forbidden to strike with a hammer or the like to prevent the bearing or gear from being damaged by excessive axial force or radial force. Be sure to tighten the mounting bolts before tightening the tightening bolts. Before installation, wipe the anti-rust oil of the motor input shaft, positioning boss and Speed reduction gearbox connection with gasoline or zinc-sodium water.

The Speed reduction gearbox is a power transmission mechanism that uses a speed converter of a gear to decelerate the number of revolutions of the motor to a desired number of revolutions and obtain a mechanism of a large torque. In the current mechanisms for transmitting power and motion, the range of applications of the Speed reduction gearbox is quite extensive. It can be seen in almost all types of mechanical transmission systems, from ships, cars, locomotives, heavy machinery for construction, processing equipment and automated production equipment used in the machinery industry, to everyday life. Home appliances, clocks, etc. Its application can be seen from the transmission of large power, to small loads, accurate angle transmission can see the application of the Speed reduction gearbox, and in industrial applications, the Speed reduction gearbox has the function of deceleration and increase torque. Therefore, it is widely used in speed and torque conversion equipment.

In order to improve the efficiency, the bevel helical Speed reduction gearbox generally uses non-ferrous metal as the bevel helical gear, and uses hard steel as the bevel helical. Because it is a sliding friction transmission, it will generate higher heat during operation, making the parts and seals of the Speed reduction gearbox There is a difference in thermal expansion between them, so that a gap is generated in each mating surface, and the oil is thinned due to an increase in temperature, which easily causes leakage. There are four main reasons. First, whether the material is reasonable. Second, the surface quality of the friction surface. Third, the choice of lubricating oil, whether the amount of addition is correct, and the fourth is the assembly quality and the use environment.

The bevel helical gear is generally made of tin bronze. The paired bevel helical material is generally hardened with 45 steel to HRC45-55. It is also commonly used for 40C: hardened HRC50-55. Grinding to roughness RaO. 8 fcm by bevel helical grinder, when the Speed reduction gearbox is in normal operation, The bevel helical is like a hardened "sickle" that uncenses the bevel helical gear and causes the bevel helical wheel to wear. In general, this wear is very slow, like some Speed reduction gearboxes in a factory can be used for more than 10 years. If the wear speed is fast, it is necessary to consider whether the selection of the Speed reduction gearbox is correct, whether there is overload operation, the material of the bevel helical gear, the assembly quality or the use environment.
Helical gear wear
It usually occurs on a vertical mounted Speed reduction gearbox, mainly related to the amount of lubricant added and the choice of lubricant. When the vertical installation is installed, it is easy to cause insufficient oil quantity. When the Speed reduction gearbox stops running, the transmission gear oil between the motor and the Speed reduction gearbox is lost, the gear can not get the proper lubrication protection, and it is not effective during startup or operation. Lubrication causes mechanical wear and even damage.
Bearing damage
When the Speed reduction gearbox fails, even if the gearbox is well sealed, the factory often finds that the gear oil in the Speed reduction gearbox has been emulsified, the bearing has been rusted, corroded and damaged. This is because the gear oil is used during the stop and stop of the Speed reduction gearbox. The condensation caused by the heat generated after the heat is cooled; of course, it is also closely related to the bearing quality and assembly process [1].

1. Guarantee the quality of the assembly. You can purchase or make some special tools. When disassembling and installing the parts of the Speed reduction gearbox, try to avoid hitting with other tools such as hammers. When replacing gears and bevel helical gears, try to use original parts and replace them in pairs. When assembling the output shaft, pay attention to it. Tolerance fit; use a release agent or red dan oil to protect the hollow shaft to prevent wear and rust or to match the area scale, which is difficult to disassemble during maintenance.
2. Selection of lubricants and additives. The bevel helical Speed reduction gearbox generally uses 220# gear oil. For heavy-duty trucks with heavy load, frequent start and poor use environment, some lubricating oil additives can be used to make the gear oil still adhere to the gear surface when the Speed reduction gearbox stops running, forming protection. Membrane to prevent heavy load, low speed, high torque and direct contact between metals at start-up. The additive contains a seal regulator and a leak preventer to keep the seal soft and elastic, effectively reducing oil leakage.
3. Selection of the mounting position of the Speed reduction gearbox. When possible, do not use a vertical installation. When installing vertically, the amount of lubricating oil added is much more than that of horizontal installation, which may cause heat generation and oil leakage of the Speed reduction gearbox.
4. Establish a lubrication maintenance system. The Speed reduction gearbox can be maintained according to the “five-set” principle of lubrication work. Every Speed reduction gearbox has a responsible person to check regularly and find that the temperature rise is obvious. If the temperature exceeds 40°C or the oil temperature exceeds 80°C, the quality of the oil will drop or oil. When more copper powder is found and abnormal noise is generated, stop using it immediately, repair it in time, troubleshoot it, and replace the oil. When refueling, pay attention to the amount of oil to ensure that the gear unit is properly lubricated.

Maintenance method editing
For the wear problem, the traditional solution of the enterprise is repairing after repair welding or brush plating, but both have certain drawbacks: the thermal stress generated by the repair welding high temperature cannot be completely eliminated, which may cause damage to the material and cause the parts to bend or break; Brush plating is limited by the thickness of the coating, and it is easy to peel off. The above two methods use metal to repair the metal, which can not change the "hard to hard" coordination relationship. Under the combined action of each force, it will still cause re-wear. For some large bearing companies, it is often impossible to solve on-site and rely on external repair. In the contemporary Western countries, the repair methods of polymer composite materials are often used for the above problems, and the application of Mikawara technology products with more applications has superior adhesion and excellent compressive strength. The application of polymer material repair can be free of disassembly and machining without the influence of repair welding thermal stress, and the thickness of the repair is not limited. At the same time, the metal material of the product does not have the concession, which can absorb the shock vibration of the equipment and avoid the wear again. It is possible, and greatly extends the service life of equipment components, saving a lot of downtime for the enterprise and creating huge economic value. For the leakage problem, the traditional method needs to disassemble and open the Speed reduction gearbox, replace the sealing gasket or apply the sealant, which is not only time-consuming and laborious, but also difficult to ensure the sealing effect, and leakage will occur again during operation. The polymer material can be used to treat leakage on the spot. The material has excellent adhesion, oil resistance and 350% elongation, which overcomes the impact caused by the vibration of the Speed reduction gearbox, and solves the problem of leakage of the Speed reduction gearbox for the enterprise.

The main functions of the Speed reduction gearbox are:

1) Reduce the speed and increase the output torque at the same time. The torque output ratio is multiplied by the motor output and the reduction ratio, but it should be noted that the rated torque of the Speed reduction gearbox cannot be exceeded.

2) Deceleration also reduces the inertia of the load, and the reduction of inertia is the square of the reduction ratio. You can see that the general motor has an inertia value.

2. How the Speed reduction gearbox works

The Speed reduction gearbox is generally used for low-speed and high-torque transmission equipment. The motor, the internal combustion engine or other high-speed power is transmitted through the gears on the input shaft of the Speed reduction gearbox to mesh the large gears on the output shaft to achieve the purpose of deceleration. The Speed reduction gearbox will also have several pairs of identical principle gears to achieve the desired deceleration effect. The ratio of the number of teeth of the large and small gears is the transmission ratio.
