The hardness of tooth surface can reach 45~55HRC.
Connection mode between of Planetary lowering drive and servo motor: holding mode – result shaft of servo electric motor extends into of Planetary reduction drive, servo engine and Planetary reduction travel are linked by flange. You will find a deformable hoop in Planetary lowering drive. By operating the locking screw on Planetary decrease travel, the hoop can tighten the axis of the servo electric motor (the author includes a 0.75KW servo electric motor with this connection). Thus for this connection method, servo motors do not need keyway (of lessons, keyway may also be, but purchasing keyway servo motors requires Money and delivery time are longer yo @ @). A kind of
Connecting mode of_of Planetary decrease drive and servo motor: Connecting through external coupling. This connection mode uses exterior coupling, so that it needs servo electrical and keyway. External coupling can also use versatile coupling (flexible shaft) – smooth shaft drive ability generally does 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 purchase the servo motors with brakes and keyways, the delivery period is for a longer time, about 4 weeks.
Planetary reduction drive in the use of the process there will be some noise, the emergence of the noise, how exactly to deal with it?
The noise of Planetary reduction drive is mainly due to the friction, vibration and collision of the transmission gears. How exactly to efficiently reduce and reduce the noise to make it more in line with the requirements of environmental protection is also an integral research topic at home and abroad.Reducing the gear transmission sound of Planetary reduction travel has become a crucial research matter in the market. Many scholars in the home and abroad respect the change of equipment tooth engagement stiffness in gear transmission as the primary factor of gear powerful load, vibration and noises.By modifying the form, the dynamic load and velocity fluctuation are minimized to reduce the noise.This technique has became more effective in practice.But with this technique, the process will need shape modification equipment, the majority of small factories often can’t be implemented.
Planetary reduction drive is definitely a sort of of Planetary reduction travel, what’s the transmission structure of planetary gear?Let’s have a look.
A planetary gear includes a sun wheel, a planetary wheel, and a gear ring, wherein the planetary wheel is supported by a fixed axis of the planetary framework, allowing the planetary steering wheel to rotate on the helping axis.The planetary wheel, sunlight wheel and the gear ring are in continuous meshing state.
Located in the center of the planetary equipment transmission mechanism may be the sun wheel, sunlight wheel and the earth wheel typically engage, two external equipment meshing rotation direction is normally opposite.Just as sunlight is at the center of the solar program, the solar wheel is named for its location.Gear band is the interior gear, it and the planet wheel often meshing, may be the inner tooth and the external gear meshing, the rotation direction between the two is the same.The quantity of planetary gear depends upon the look load of the Planetary reduction travel, usually 3 or 4, the more the amount of bear the load is greater.
The above may be the Planetary reduction travel gear transmission structure of the key content.
Planetary speed of Planetary reduction drive is usually a sort of speed of Planetary reduction drive, in that case, 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 wrong type variety causes insufficient end result torque of the Planetary reduction drive.
Some users in the model selection, mistakenly given that the selected rated productivity torque Planetary reduction drive to meet the work requirements can be, in fact, it isn’t, one may be the rated outcome torque of the electric motor rated output torque situations deceleration ratio, the worthiness obtained in principle ought to be less than the merchandise sample to provide similar Planetary reduction travel rated end result torque.The other is to consider the overload capacity of the drive electric motor and the utmost operating torque required used.
2. Along the way of acceleration and deceleration, the instantaneous torque borne by the output shaft of the Planetary decrease drive exceeds 2 times of its rated output torque, and this sort of acceleration and
deceleration can be too frequent, which will eventually make Planetary lowering travel break the shaft.
Theoretically, the utmost operating torque required by an individual must be significantly less than two times the rated output torque of the Planetary reduction drive, especially in a few 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 driving motor will still make it constantly improve the output force, which might cause the force of the output bearing of the Planetary reduction travel to exceed its rated output torque two times and so twist the output shaft of the Planetary reduction drive.

With the Ever-Electric power mountain drive you get additional suprisingly low gears which permit you go climb the most extreme torque Gears: 1:1 and 2.5:1 reduction gear ratio.
The initial step is to confirm whether the electric motor and Planetary reduction travel are in good condition before installation, and strictly check whether the size of every part connected with the motor and Planetary reduction travel is matched. Here are the size and coordinating tolerance of the positioning boss, input shaft and Planetary reduction travel groove of the engine.
Step 2 2: unscrew the screw on the external dustproof hole of of Planetary lowering drive flange, adjust the clamping band of PCS system to align the medial side hole with the dustproof hole, insert the interior hexagon to tighten.After that, remove the motor shaft keys.
The third step is to hook up the motor with Planetary reduction drive by natural means.The concentricity of the output shaft of Planetary reduction drive and the input shaft of the engine must be steady when connected, and the external flange of both should be parallel.If the concentricity is not consistent, the engine shaft will be broken or of Planetary decrease drive gear wear.
Furthermore, in the installation, usually do not use hammer and different blows, prevent the axial force or radial force an excessive amount of damage to the bearing or equipment.Make sure you tighten the installation bolt just before tightening the pressure 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 flexibility of operation, and prevent unnecessary deterioration.
Prior to the motor and Planetary lowering drive are connected, the motor shaft keyway should be perpendicular to the tightening bolt.To ensure a uniform force, 1st screw the unit installation bolts at any diagonal position, but usually do not screw limited, then screw the installation bolts at the additional two diagonal positions, and lastly screw the four installation bolts one by one.Finally, tighten the force bolt.All tightening bolts will be fixed and examined by the torque plate hand according to the indicated torque data.
Right installation between of Planetary reduction drive and mechanical apparatus is the same as accurate installation between of Planetary reduction travel and drive engine.The key is to make sure that the output shaft of Planetary reduction drive and the drive part of the shaft concentricity.
servo engine of Planetary reduction drive Planetary reduction drive of Planetary reduction drive rated input increase to 18000 RPM (about of Planetary reduction travel itself size, the higher the rate of Planetary reduction travel, small the rated input acceleration) above, industrial-grade servo electric motor of Planetary reduction drive output torque is normally only 2000 nm, special significant torque servo electric motor of Planetary reduction drive can do more than 10000 nm. Working temperatures in 25 ℃ to 100 ℃ roughly, by changing the grease can change its working heat range.Planetary reduction travel: the main transmission structure is normally: planetary wheel, solar wheel, outer gear ring.Compared with various other reduction gear, servo electric motor reduction gear has excessive rigidity, high precision (sole stage can achieve less than 1 point),(double stage can achieve less than 3 points), high transmission effectiveness (single stage in 95-99%), high torque/volume ratio, life free of maintenance features.Due to these characteristics, servo electric motor of Planetary reduction travel is mostly installed in the stepper motor and servo motor or brushless electric motor, used to lessen the speed, enhance the torque, matching inertia.Ranked input speed of servo engine of Planetary reduction travel can are as long as 18000rpm(related to how big is Planetary reduction drive itself.
