The combination of the two errors forms a tooth-tangential comprehensive error Δfi along the tangential direction, and a radial integrated error Δf′′i is formed along the radial direction. The comprehensive index and the one-way index are comprehensive, accurate and reliable due to the comprehensive index. In order to correctly evaluate the working quality of the gears, the comprehensive index is better, and the single index with mutual compensation is not used.
Because sometimes individual indicators are unqualified, their comprehensive indicators may be qualified. In addition, the test for continuous measurement can reflect the gear error more comprehensively than the discontinuous measurement index, and the comprehensive test is closer to the gear use than the single test, and the measurement efficiency is also high. When selecting a comprehensive tolerance project, only one item is required in each tolerance group. If a single index is selected, in addition to the low-precision grade gear, in order to comprehensively evaluate the gear precision, it should be combined, for example, the combination of â–³Fr and â–³Fw .
Since the gear is a geometrically complex part, the factors affecting the error may be equivalent or not equivalent. If the error of the single item is out of tolerance and the comprehensive error of the screw unit is not exceeded, the gear is judged to be a qualified product. If △F′′i and △Fw or △Fr and △Fw are used for evaluation, if one of the indicators is out of tolerance, one item is qualified, the gear should not be scrapped, but should be △F?i or △Fp Comment. Because it is considered that the geometric eccentricity and the motion eccentricity on the same gear may overlap or cancel each other, if △F?i or △Fp is qualified, the gear is qualified.
Scrap SHREDDER is a shredding machine used to produce scrap shredded materials, mainly used for scrapping cars, scrapped household appliances and thin scrap steel machines. The shell of the main engine is made of extra-thick steel plate, and the inner lining is made of high-manganese cast steel, which can be replaced. Our scrap shredders also provide customers with other equipment to form a complete scrap shredding line. The main equipment of scrap crushing line includes scrap feeding conveyor, crusher and scrap discharging conveyor.
Application
The scrap shredder can be used to shred the whole car body or the flattened car body, household appliances, bicycle body, empty cans, etc.
