Stage electric hoist gear is worn how to do?

Stage electric  Wire rope hoist  is mainly used for stage touring other places, for lifting audiovisual, lighthouse, etc., according to today's technical staff to solve real-world experience to your Weapon occur when the stage hoist gear wear how to do?
Stage electric hoist gear on another failure mode is wear, worn tooth thinning. If the lubricating oil wear caused impurities, generally referred to abrasive wear. This wear is often the top and root of the tooth appears deep scratch Road, scraping road perpendicular to the section line and parallel to each other. Scraping road appears, oil temperature rise inside the reducer, gear transmission occurs shrill noise, then you must change the oil.

Because tooth deviation installation center distance deviation is too large, may cause the top edge of the gear teeth and the tooth root portion of the transition curve excessive compression, so that part of the tooth root fillet produce severe wear. Due to overload, tends to make the driving wheel or the driven pulley tooth tip (sometimes also be along the entire tooth surface) of a thin layer is worn away.
Stage electric lift hoist  for lifting mechanism gear reducer wear, tooth thickness of not less than 60% of the original tooth thickness, for operating agencies gear worn tooth thickness of not less than 80% of the original tooth thickness, more than the standard should be replaced with new gear . Tooth wear can be measured with a thick tooth caliper measurement of the pitch circle tooth thickness to test. Gear measuring caliper vernier caliper and depth gauge is integrated caliper for measuring tooth thickness.manual hoist Measurement, start drawing isolated tooth height, the measured vertical scale adjusted tooth caliper this height. Then, the card pin stuck teeth, tooth thickness measurements using the horizontal scale.
