In Planetary reduction drive family, the Planetary reduction drive with its little size, high tranny efficiency, wide reduction range, high precision many advantages, and is trusted in servo, stepping, dc and various other transmitting systems.Its function is in the premise of ensuring precision transmitting, mainly used to lessen the rotation rate and increase torque and decrease the load/motor rotational inertia ratio.In order to help the majority of users to create good usage of the Planetary reduction drive, this paper analyzes the sources of Planetary reduction drive and the drive engine shaft breaking, and introduces in detail how to properly install the Planetary reduction drive.
Correct installation, use and maintenance of of Planetary reduction drive is certainly an important hyperlink to ensure the standard operation of mechanical equipment.As a result, when you install the Planetary reduction drive, make sure you make certain to strictly follow the following installation related matters, thoroughly assemble and use.
The first step is to confirm if the motor and Planetary reduction drive are intact before installation, and strictly check if the size of each part connected with the electric motor and Planetary reduction drive matches, this is actually the size of the positioning boss, input shaft and Planetary reduction drive groove of the engine and matching tolerance.
The next step is to unscrew the screw on the outer dustproof hole of Planetary reduction drive flange, adjust the clamping ring of PCS system to align the medial side hole with the dustproof hole, insert the inner hexagon to tighten.From then on, take away the motor shaft keys.
Surface hardening editing
Common surface quenching methods are high-frequency quenching (for little gears) and flame quenching (for large gears).The top hardened layer works best when it includes the base of the tooth root.The common material for surface quenching is steel whose mass fraction of carbon is approximately 0.35%~0.5%. The hardness of tooth surface area can reach 45~55HRC.
Connection mode between of Planetary reduction drive and servo motor: holding mode – result shaft of servo engine extends into of Planetary reduction drive, servo motor and Planetary decrease drive are connected by flange. There is a deformable hoop in Planetary reduction drive. By operating the locking screw on Planetary decrease drive, the hoop can tighten the axis of the servo motor (the author has a 0.75KW servo motor with this connection). So for this connection setting, servo motors usually do not need keyway (of program, keyway may also be, but purchasing keyway servo motors needs Money and delivery time are longer yo @ @). A kind of
Linking mode of_of Planetary reduction drive and servo electric motor: Connecting through exterior coupling. This connection mode uses exterior coupling, so that it needs servo electric and keyway. Exterior coupling may also use flexible coupling (flexible shaft) – soft shaft drive power generally will not exceed 5.5KW, speed may reach 20000 rpm. Some sort of
Generally speaking, the servo motors without brakes and keyways are the the majority of used and the Ever-Power is the largest. Consequently, to order the servo motors with brakes and keyways, the delivery period is definitely longer, about four weeks.
Planetary reduction drive in the use of the process you will have some noise, the emergence of the noise, how to deal with it?
Planetary reduction drive
The noise of Planetary reduction drive is principally caused by the friction, vibration and collision of the transmission gears. How exactly to efficiently reduce and reduce the noise to make it more good requirements of environmental safety is also an integral research topic in the home and abroad.Reducing the gear transmission noise of Planetary decrease drive has become an important research subject in the industry. Many scholars in the home and abroad regard the change of gear tooth engagement stiffness in equipment transmission as the primary factor of gear powerful load, vibration and noise.By modifying the shape, the dynamic load and velocity fluctuation are minimized to reduce the noise.This method has became more effective in practice.But with this method, the process needs to have shape modification equipment, nearly all small factories often can’t be implemented.
Planetary reduction drive is usually a kind of of Planetary reduction drive, what is the transmission structure of planetary gear?Let’s have a look.
A planetary gear includes a sun wheel, a planetary wheel, and a gear band, wherein the planetary wheel is supported by a set axis of the planetary frame, allowing the planetary wheel to rotate on the supporting axis.The planetary wheel, the sun wheel and the gear ring are in constant meshing state.
Located in the center of the planetary equipment transmission mechanism is the sun wheel, the sun wheel and the earth wheel frequently engage, two external gear meshing rotation direction can be opposite.Just as sunlight is at the center of the solar program, the solar wheel is named because of its location.Gear ring is the inner gear, it and the planet wheel often meshing, is the inner tooth and the outer gear meshing, the rotation direction between the two may be the same.The number of planetary gear depends upon the look load of the Planetary reduction drive, usually 3 or 4, the more the amount of bear the load is greater.
The above is the Planetary reduction drive equipment transmission structure of the primary content.
Planetary speed of Planetary reduction drive is certainly a kind of speed of Planetary reduction drive, after that, the planetary speed of Planetary reduction drive along the way of using the reason for the shaft break what?Let’s take a look.
1. The incorrect type selection causes insufficient result torque of the Planetary reduction drive.
Some users in the model selection, mistakenly provided that the selected rated result torque Planetary reduction drive to meet the work requirements can be, in fact, it is not, one is the rated output torque of the motor rated output torque moments deceleration ratio, the value obtained in principle should be less than the product sample to provide similar Planetary reduction drive rated output torque.The other is to consider the overload capacity of the drive electric motor and the maximum operating torque required used.
2. Along the way of acceleration and deceleration, the instantaneous torque borne by the result shaft of the Planetary reduction drive exceeds two times of its ranked output torque, and such acceleration and deceleration can be too frequent, that will eventually make Planetary reduction drive break the shaft.
Theoretically, the maximum operating torque required by an individual must be less than two times the rated output torque of the Planetary reduction drive, especially in some applications must strictly comply with this criterion.This is not only to protect the Planetary reduction drive, but also to prevent the output shaft of Planetary reduction drive from being twisted off.The main reason is that, when there is a problem in equipment installation, the output shaft of the Planetary reduction drive and its own load are stuck, the overload capacity of the traveling motor will still make it constantly boost the output force, which might cause the force of the output bearing of the Planetary reduction drive to exceed its rated output torque two times and thus twist the output shaft of the Planetary reduction drive.
Precision planetary reduction drive
Product Description:
There are two main types based on the output direction: straight type and right angle type; Planetary gear systems are used to perform speed decrease due to huge torque. to predict gear noise from a rear wheel drive automatic transmission.
There are generally three types based on the number of stages: one-stage deceleration (generally less than 10:1), two-stage deceleration (generally higher than 10:1 and significantly less than or equal to 100:1), and three-stage deceleration (large reduction ratio is 100) :1, the overall division principle is higher than 100:1);

The first step is to confirm if the electric motor and Planetary reduction drive are in good shape before installation, and strictly check if the size of each part connected with the motor and Planetary reduction drive is matched. Listed below are the size and coordinating tolerance of the positioning boss, insight shaft and Planetary reduction drive groove of the engine.
Step two 2: unscrew the screw on the external dustproof hole of of Planetary reduction drive flange, modify the clamping band of PCS program to align the side hole with the dustproof hole, insert the internal hexagon to tighten.After that, remove the motor shaft keys.
The 3rd step is to connect the electric motor with Planetary reduction drive naturally.The concentricity of the output shaft of Planetary reduction drive and the input shaft of the engine must be consistent when connected, and the external flange of both should be parallel.If the concentricity is not consistent, the electric motor shaft will be broken or of Planetary reduction drive gear wear.
Furthermore, in the installation, do not use hammer and other blows, prevent the axial force or radial force too much harm to the bearing or equipment.Be sure to tighten the mounting bolt before tightening the power bolt.Before installation, wipe aside the anti-rust oil of motor input shaft, positioning boss and connecting part of of Planetary reduction drive with gasoline or zinc-sodium water.Its purpose is to ensure tight connection and versatility of operation, and prevent unnecessary wear and tear.
Planetary reduction drivePlanetary reduction drive
Before the motor and Planetary reduction drive are linked, the motor shaft keyway should be perpendicular to the tightening bolt.To ensure a uniform force, first screw the installation bolts at any kind of diagonal position, but usually do not screw restricted, then screw the installation bolts at the various other two diagonal positions, and lastly screw the four set up bolts one by one.Finally, tighten the force bolt.All tightening bolts shall be fixed and examined by the torque plate hand according to the indicated torque data.
Appropriate installation between of Planetary reduction drive and mechanical tools is the same as appropriate installation between of Planetary reduction drive and drive electric motor.The key is to make sure that the output shaft of Planetary reduction drive and the drive portion of the shaft concentricity.
