How do wear worm screw lift worm screw lift generally use bronze, worm material is generally paired with 45 steel hardened to HRC45 a 55, also commonly 40C: hardened HRC50 a 55, the worm Grinding to roughness RaO SL3550 heavy lift,. 8 fcm, reducer normal operation, the worm is like a hardened "rasp", constantly cutting and filing worm, the worm wheel wears. In general, this wear is very slow, like a factory, some gear can be used for more than 10 years. If you wear faster, we must consider whether the correct gear selection, if there is overload operation, worm material, assembly quality or environmental reasons. Screw jack screw lift, also known as the internal screw jacks are for most worm structure, or a bevel gear structure. 1. Lift the model, filling oil also differ. SJ screw jacks as is the use of high frequency SL20 special, customized spiral bevel gear screw hoist, if customers use frequency is too high, you must use a liquid industrial gear oil, if using lithium grease lubrication of industrial lifts, lubrication the effect is greatly reduced, but also prone to thermal and other issues, so that the worm gear excessive wear. By GB SWL screw lift lubrication in most other lifts same, using a 0000 # industrial lithium grease lubrication, the degree of use of lifts are not frequent, SL lifts, industrial lithium grease can play a good role in lubrication. 2. With regard to section lubricated screw lifts, screw part in the process of using, but also long-term exercise, although the movement is slow, but the lubrication on the screw is also essential, in this screw lubrication, We recommend the use of grease lubrication, butter because with strong sticky type, in the case of running fast enough, will apply to the entire root butter screw, during use, better lubrication. 3. The oil change problem, lifts in use, many models need to be replaced or continue to add lubricants, SJ screw jacks raise the industry because it is a liquid lubricant, such as frequency of use more frequently, should be less than a month's time replace a worm gear box oil, but for the ordinary GB SWL screw lift, we only need to periodically observe the situation inside the grease, inside the absence of filling on it.
