The hardness of tooth surface area can reach 45~55HRC.
Connection mode between of Planetary reduction drive and servo engine: holding mode – productivity shaft of servo motor extends into of Planetary decrease drive, servo electric motor and Planetary reduction travel are connected by flange. There exists a deformable hoop in Planetary lowering drive. By working the locking screw on Planetary decrease drive, the hoop can tighten the axis of the servo electric motor (the author includes a 0.75KW servo electric motor with this connection). And so for this connection method, servo motors usually do not need keyway (of course, keyway can also be, but buying keyway servo motors needs Money and delivery period are longer yo @ @). A kind of
Linking mode of_of Planetary decrease drive and servo electric motor: Connecting through external coupling. This connection function uses exterior coupling, so it needs servo electric and keyway. External coupling may also use versatile coupling (flexible shaft) – very soft shaft drive electricity generally does not go beyond 5.5KW, speed can reach 20000 rpm. Some sort of
In most cases, the servo motors without brakes and keyways will be the the majority of used and the Ever-Power is the largest. For this reason, to purchase the servo motors with brakes and keyways, the delivery period is much longer, about 4 weeks.
Planetary reduction travel in the utilization of the process you will see some noise, the emergence of the noise, how 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 properly reduce and decrease the noise to create it more based on the requirements of environmental protection is also an integral research topic in the home and abroad.Reducing the gear transmission noises of Planetary reduction drive has become an essential research subject matter in the industry. Many scholars in the home and abroad regard the change of equipment tooth engagement stiffness in equipment transmission as the key factor of gear powerful load, vibration and sound.By modifying the form, the powerful load and velocity fluctuation are minimized to reduce the noise.This technique has proved to be 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’s the transmission structure of planetary gear?Let’s take a look.
A planetary gear includes a sun wheel, a planetary steering wheel, and a gear ring, wherein the planetary wheel is supported by a set axis of the planetary framework, allowing the planetary wheel to rotate on the helping axis.The planetary wheel, sunlight wheel and the apparatus ring are in constant meshing state.
Located in the guts of the planetary equipment transmission mechanism may be the sun wheel, the sun wheel and the earth wheel typically engage, two external equipment meshing rotation direction is normally opposite.Just as sunlight is at the guts of the solar system, the solar wheel is known as for its location.Gear ring is the inner gear, it and the earth wheel often meshing, is the inner tooth and the external gear meshing, the rotation direction between the two is the same.The number of planetary gear depends on the look load of the Planetary reduction drive, usually three or four, the more the amount of bear the strain is greater.
The above may be the Planetary reduction travel equipment transmission structure of the key content.
Planetary speed of Planetary reduction drive is certainly a kind of speed of Planetary reduction drive, then, 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 selection causes insufficient end result torque of the Planetary reduction drive.
Some users in the unit selection, mistakenly provided that the selected rated end result torque Planetary reduction travel to meet up the work requirements can be, in fact, it is not, one may be the rated outcome torque of the electric motor rated output torque situations deceleration ratio, the value obtained in principle ought to be less than the product sample to provide similar Planetary reduction travel rated outcome torque.The other is to consider the overload capacity of the drive engine and the maximum operating torque required in practice.
2. In the process of acceleration and deceleration, the instantaneous torque borne by the result shaft of the Planetary reduction drive exceeds 2 times of its ranked output torque, and such acceleration and deceleration can be too frequent, that will eventually make Planetary lowering drive break the shaft.
Theoretically, the maximum operating torque required by the user 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 avoid the output shaft of Planetary reduction drive from being twisted off.The main reason is that, if 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 boost the output force, which may cause the force of the output bearing of the Planetary reduction travel to exceed its rated output torque 2 times and so twist the output shaft of the Planetary reduction travel.

With the Ever-Ability mountain drive you get additional suprisingly low gears which permit you move climb the the majority of extreme torque Gears: 1:1 and 2.5:1 reduction gear ratio.
The initial step is to verify whether the engine and Planetary reduction drive are in good condition before installation, and strictly check whether the size of every part connected with the motor and Planetary reduction drive is matched. Listed below are the size and coordinating tolerance of the positioning boss, suggestions shaft and Planetary lowering drive groove of the motor.
Step two 2: unscrew the screw on the outer dustproof hole of of Planetary decrease drive flange, adapt the clamping ring of PCS program to align the medial side hole with the dustproof hole, insert the interior hexagon to tighten.After that, take away the motor shaft keys.
The third step is to connect the engine with Planetary reduction travel naturally.The concentricity of the output shaft of Planetary reduction travel and the input shaft of the electric motor must be steady when connected, and the outer flange of the two 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, avoid the axial force or radial force an excessive amount of harm to the bearing or equipment.Be sure to tighten the mounting bolt just before tightening the induce bolt.Before installation, wipe apart the anti-rust oil of motor input shaft, positioning boss and connecting component of of Planetary reduction drive with gasoline or zinc-sodium water.Its purpose is to make sure tight connection and flexibility of operation, and stop unnecessary deterioration.
Before the motor and Planetary reduction drive are connected, the motor shaft keyway ought to be perpendicular to the tightening bolt.To make sure a uniform force, initially screw the unit installation bolts at virtually any diagonal position, but do not screw limited, then screw the unit installation bolts at the different two diagonal positions, and lastly screw the four set up bolts one at a time.Finally, tighten the force bolt.All tightening bolts will be fixed and examined by the torque plate hand based on the indicated torque data.
Accurate installation between of Planetary reduction travel and mechanical equipment is the same as appropriate installation between of Planetary reduction travel and drive electric motor.The main element is to make sure that the output shaft of Planetary reduction travel and the drive part of the shaft concentricity.
