Geared motor is a kind of open loop control motor, it converts electrical pulses to angular displacement or linear displacement. In the case of no step loss, the motor speed and stop position only depends on the pulse signal frequency and pulse number, not influenced by load.
When the gear reduction motor receives the pulse signal, 12 Volt Motor With Gearbox the influence of the change, the motor set along the direction of fixed point of view, known as the step Angle, and by controlling the pulse number and pulse frequency to control motor angular displacement and speed of the motor, so as to realize the open loop control.
In addition, the gear reduction motor interval between each rotation Angle and the theory, there are always some error in one step after step, there is always a certain error but geared motor steps per revolution of the same, and step into the cumulative error doesn't grow on time without loss of steps.
If you want to avoid the gear reduction motor out of step, only choose correct and appropriate stepper drive, gear reduction motor to take advantage of its precise control. Choose the appropriate drive needs according to the motor current matching High Torque 12v Dc Motor a greater than or equal to the current drive. When need low vibration or high precision subdivision drive may be used. For high torque motor, use high voltage driver as far as possible in order to obtain good performance at a high speed. For the gear reduction motor driving power, can use a conventional toroidal drive or R type transformer or transformer DC power supply.
In order to improve the efficiency, worm gear reducer is generally adopt nonferrous metal worm gear, worm, the use of the hard steel. Is due to sliding friction transmission, generates more heat in operating, decelerate machine thermal expansion Vending Machine Motor differences between the parts and seal in the mating surface form clearance, lubricating oil, due to the rise of temperature is thinning is easy to cause leakage. Cause there are four main reasons for this, it is material collocation is not reasonable; Second, the poor quality of mesh on the surface of the friction surface; 3 it is to select the amount of lubricating oil added is not correct; Four is the difference in assembly quality and the use of the environment.
Tin bronze commonly used worm gear, worm pairs, the materials with hardening of 45 steel to HRC4555, or 40 cr hardened HRC5055 via worm grinder grinding to roughness Ra0.8 microns. Reducer running wear very slow, some reducer can be used more than 10 years. If wear faster, consider selection is correct, whether the overload operation, as well as the material of worm gear and worm, assembly quality and using the environment.

After a geared motor factory, general provisions have 200 hour period must be oil change (over time), which is geared mechanical technical characteristics and regulations governing the use of the early. Period is to guarantee the normal operation of the gear reducer, reduce the failure rate, prolong the service life of important link.
Wear speed because of the new gear speed reducer parts Micro Gear Motor processing, assembly and debugging, the influence of such factors as cooperate with the surface contact area is lesser, and the allowable torque is larger. Gear speed reducer in the process of running, concave and convex part chimeric friction each other on the surface of the parts, grinding of metal debris fell down, and as an abrasive, continue to participate in friction, accelerate the abrasion on the surface of the parts with more. The running-in period, therefore, easy to the wear and tear parts (especially with surface), wear too fast. At this moment, if the seams, may cause the damage of the parts, early failure.
Error due to the more understanding of the structure of the gear motor, the performance is not enough (especially new operator), easy fault caused by error, and even cause mechanical accident and safety accidents.
Bad lubrication because of the new assembly parts fit clearance is small, and due to reasons such as assembly, lubricating oil (grease) in less friction surface uniform oil film formation, to prevent wear and tear. Reducing lubrication performance, causing the early abnormal wear and tear parts. Caused serious precision of friction surface scratch or bite phenomenon, lead to failure.
Deceleration motor reducer and the integration of the body Low Rpm Electric Motor (motor). This integration can also often called the body gear motor or gear motor. Gear motor is widely used in steel industry, machinery industry, etc. An advantage of using the gear motor is simplified design, save a space. Gear motor usually has the following advantages:
1, After precision machining, to ensure the position precision, all these constitute the gear reduction motor of gear transmission assembly is configured with all kinds of motor, formed the mechanical and electrical integration, fully guarantee the quality of the products use features.

3, Small vibration, low noise, high energy saving, Gear Reduction Motor choose optimal steel material, semi steel box, gear surface after high frequency heat treatment.
4, Low energy consumption, superior performance, reducer efficiency is as high as above 95%.
5, Products used seriation, modular design thought, has a wide range of adaptability, the series of products have more motor combination, installation position and structure scheme.
6, Aave a space, reliable and durable, high overload capacity.

With the development of society and production needs, micro gear motor the application of the gear speed reducer is more and more widely, in the textile, manufacturing, processing, transportation, construction and other industry has a pivotal position, gear speed reducer for these devices usually have the effect of transmission and slow.
In general, the gear is the most important parts in the gear reducer, gear reducer overall not largely depends on the gear machining accuracy and reliable quality, then the gear speed reducer gear quality how to improve?
Improve the gear processing precision of the gear speed reducer
Main gear reducer shaft gear precision and movement Small Geared Motors accuracy, the smoothness of precision, accuracy of contact. Gear reducer gear hobbing machining with control the common normal length and jump to ensure the movement precision gear ring diameter, with control of tooth profile error and base pitch deviation to ensure accuracy of working stability, control gear to error to ensure that the contact accuracy.
Reduce the gear speed reducer gear ring radial runout error
Gear reducer gear ring radial runout refers to the gear a transfer within the scope of probe on the tooth or tooth groove, contact with the school is double sided, probe axis is the measure of the change of the relative to the gear. Also is the tooth gear ring gear speed reducer eccentric relative to the shaft centerline, the eccentric is because when installing a gear speed reducer parts, parts of the two center hole and the rotary center of the workbench installed do not overlap or deviation caused by too much. Or because of the gear speed reducer top and top hole producing bad, bad make contact surface caused by the eccentric, so reduce the gear speed reducer gear ring radial runout error can effectively improve the quality and precision of gear.
Wear speed because of the new gear speed Small Dc Gear Motor reducer parts processing, assembly and debugging, the influence of such factors as cooperate with the surface contact area is lesser, and the allowable torque is larger. Dongguan gear speed reducer in the process of running, concave and convex part chimeric friction each other on the surface of the parts, grinding of metal debris fell down, and as an abrasive, continue to participate in friction, accelerate the abrasion on the surface of the parts with more. The running-in period, therefore, easy to the wear and tear parts (especially with surface), wear too fast. At this moment, if the seams, may cause the damage of the parts, early failure.
Bad lubrication because of the new assembly parts fit clearance is small, and due to reasons such as assembly, lubricating oil (grease) in less friction surface uniform oil film formation, to prevent wear and tear. Reducing lubrication performance, causing the early abnormal wear and tear parts. Caused serious precision of friction surface scratch or bite phenomenon, lead to failure.

If the hardness of gear motor cannot conform to gear reduction motor the standard, use for a long time, or when used in the overload environment will accelerate hard tooth surface gear wear and tear, and thus affect the normal operation of the transmission device. In order to make the normal operation of equipment, to prevent unnecessary damage, can through the following way to solve the problem of wear and tear of equipment:
When a gear motor, gear shaft hole wear, but the plating method is adopted to restore the original precision to the parts.
Second, if the gear tooth broken damage dispersion machine, such as coating dispersion machine, laboratory dispersion machine, vacuum machine, can't repair, must rework the new parts.
Three gear motor, timely cleaning, practice may not replace any hardware facilities, do not add detergent, to ensure the safe operation of the gearbox.
Four, to choose a good model specifications, to ensure that the mechanical safety coefficient, strictly in accordance with the operational procedures to use, to bring its efficiency.
Geared motor in processing and manufacturing, wear and tear problems, we must solve the above several ways, if it cannot solve, we must find specialized technical personnel to solve.
Reducer bearing under the condition of normal installation and small geared motors lubrication maintenance, working can be used to the bearing surface caused by fatigue flake material, which can be used to the calculation of bearing life is terminated, sometimes can also more than design life many times.
And in the course of actual use, often due to premature damage of rolling bearing and scrap, bearing the premature failure can come from bad of bearing manufacturing defects and bearing material, but more is from improper use, maintenance and lubrication of the bearing etc. To find out the cause of the damage of bearing correctly to be difficult, a slightly damaged bearing from bearing uغير مجاز مي باشدe, especially bearing wear condition, wear track on the surface of the work and so on to analyze the cause of the damage.
