Electric wire rope hoist

After the wire rope hoist used for some time , the gear will be worn, what is the reason for this liftech motorized chain hoist phenomenon is formed below us ; ? Do a detailed analysis .
Transmission gear wire rope hoist on another failure mode is wear, worn tooth thinning. If there is wear due to impurities in the oil , generally referred to abrasive wear. This wear often occurs in the deep channel scraping tooth top and root scraping section perpendicular to the line track and parallel to each other . After scraping the road appears to rise in the gear unit oil , gear shrill noise occurs , then you must replace the oil . Because tooth deviation installation center distance deviation is too large , may cause tooth gear pair top edge portion of the transition curve and the tooth root excessive compression , so that part of the tooth root fillet produce severe wear. Due to overload , tends to make the drive wheel tooth or teeth of the driven pulley of the top ( also sometimes occur along the entire tooth surface) of a thin layer is worn away . Lifting gear reducer mechanism for the wear, tooth thickness of not less than 60% of the original tooth liftech portable electric hoist thickness for wear after running gear tooth thickness institutions should not be less than 80% of the original tooth thickness exceeds the standard should be replaced with new gear . Tooth wear can be measured with a thick tooth pitch circle caliper measurements to test the tooth thickness . Measuring method shown in FIG . Caliper Caliper is a comprehensive measure tooth vernier caliper and depth gauge , used to measure tooth thickness . When measuring , starting with drawings isolated tooth height ( ie, from division to round the top of the tooth height ) , the vertical scale measuring tooth caliper raised the height. Then, the card foot stuck teeth , tooth thickness measurement with a level of scale . Measurement accuracy up to 0.02mm.
