Screw lift the generation gap is generally divided into two areas: one in the course of long-term use of screw lift generated by friction, worm and screw every rotation will have a little friction, friction has generated a lot of heat, if it is at a high frequency, high usage conditions, the heat of this part is very large, so this part of the heat causes the bearing housing and the seals have a little bit increased phenomenon, which in turn causing microscopic worm and worm gear shift, resulting in instability, it will promote the generation of large friction, a cycle has begun. On the other hand, is produced in the worm screw jack and worm gear and screw friction between them is in direct contact with each other, the worm and the worm wheel rotating at high speed, the worm, the worm gear will have a lot of friction, and the worm wheel screw will be greater friction between them will squeeze each other, this will generate a lot of grinding material, these grinding material, under the action of friction, resulting in a large amount of powder-like objects, which will promote the worm and worm gear and screw friction swl1 screw lift, over time will cause an increase in the gap swl5 screw lift lifts, generate swing, the noise increases. So, to sum up, we use screw lift when it needs to add oil to it often, so the cooling effect produced jwm005 screw lift, if conditions allow, the screw lift the worm, silk rods, bearings split out, brought clean look, this will increase the life of the screw jack. If you do not understand where the screw lift use, please consult Dezhou Tai mechanical screw lift, nationwide toll-free number: 15269490630 Shandong Dezhou reducer Ltd. welcome you to inquire! Love to answer every day, sweepstakes Surprise ~ asker adopt a trapezoidal thread, in particular: _ Screw Machine Model Specifications (mm) SWL2.5_ Tr30x6 SWL5_ Tr40x6 SWL10_ Tr58x12 SWL15_ Tr65x12 SWL20_ Tr90x16 SWL25_ Tr110x18 SWL35_ Tr1110x20 SWL100_ Tr150x23 SWL120_ Tr180x25 above models and specifications are referring to a company Huai'an product (performance standards JB / T8809-1998) In my experience, in fact, different manufacturers, models corresponding screw specifications will be a little different, which I did not understand why, perhaps is the standard they perform are different. jwm010 screw lift _ Runchi reducer (certified) _ Fuxin screw lift provided by the Texas Runchi reducer Limited.
