Worm gear material selection and machining accuracy are also important. 10P polyoxymethylene (POM) was selected, either with glass-reinforced nylon or reinforced polycarbonate (PC). However, the overall performance of the POM is good, and the performances of the bow motion, rigidity, impact, fatigue, and creep resistance are all high. In particular, it is outstanding in fatigue resistance and easy to be molded. It is the best among thermoplastic engineering plastics, with small and stable friction coefficient, small water absorption, good dimensional stability, and low price, so it is our first choice.

In order to buffer the impact force generated in the forward and reverse direction and ensure the service life of the transmission parts, the transmission disc needs to be provided with a rubber transmission disc that is oil-resistant, wear-resistant, and highly resilient under high temperature and low thirst, and the structure size is matched with the worm gear. , embedded in the worm gear. The material is made of nitrile rubber with excellent oil resistance, and its heat resistance is also superior to natural rubber and butyl rubber. It is a metal drive plate that is matched with the rubber drive plate and embedded in the worm gear. There are 3 pieces of cloth on the disk.

The noise reduction of the motor drive plate five-shutter window motor In electromagnetic design, we first consider to suppress or reduce the motor noise. From the aspect of equipment, it is also required that the armature bearing position and the bearing chamber be the best. Choose low-noise copper-based (or iron-based) oil-bearing bearings and choose copper enamel: ink brush. The clearance between the carbon brush and the brush holder is unilaterally not greater than 0.1 llnrn. During the test run, the carbon brush contact surface should be >70%. The axial surface of the commutator on the armature is controlled within 0.01 m. In addition, the production of worm and worm gears adds precision and clearance, and the axial clearance of the motor is in a hurry; they should be strictly controlled.
