Wire rope gourd gear wear
Wire rope hoist gear wear, then in the end because of how it, here we come to a detailed analysis:
Transmission gear wear wire rope electric hoist another failure modes of wear, tooth thinning. If the abrasion caused by impurities in the lubricating oil, generally referred to as the abrasive wear. This wear often appear in the addendum and tooth root a deep scratch Road, and scraping Road is perpendicular to the section line and parallel to each other. Scraping Road emergence reducer oil temperature rise, a shrill noise gear, lubricating oil must be replaced.
Gear Vice teeth top edge and tooth root transition curve part toothed deviation installation center distance deviation is too large may cause excessive compression produce severe wear of the tooth root fillet part. Due to overload, tend to make the tooth root of the capstan or the passive wheel of the addendum (sometimes also possible along the entire tooth surface) is worn thin layer.
For the hoisting mechanism reducer gear wear, tooth thickness should not be less than the original tooth thickness, 60% run institutions gear wear, tooth thickness of not less than 80% of the tooth thickness exceeds the standard should be replaced with new gear. Wear of tooth thickness can be measured tooth caliper measurement indexing circular tooth thickness inspection. Methods of measurement are as shown. Measured teeth caliper is a caliper, vernier caliper and depth gauge is used to measure the tooth thickness. Measurement, first identified on the drawings tooth height (from the indexing circle to the addendum height), measured tooth calipers vertical scale adjusted to this height. Then, the card pin stuck to the tooth, with a horizontal scale for measuring the tooth thickness. Measurement accuracy up to 0.02mm.
