micro gear motor
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.
