sew reducer repair, Springfield Jinan, Laiwu reducer maintenance provided by the Electrical and Mechanical Equipment Co., Ltd. Jinan Springfield. Mechanical and Electrical Equipment Co., Ltd. Jinan Springfield (www.jnspray.com) is specialized in the "Siemens Flender reducer and coupling, SKF series couplings, Germany K" business, the company adhering to the "honesty, hard service "concept, to provide you with the highest quality products and services. Welcome to inquire! Contact: Manager Zhao. Disintegration of inspection reducer: 1 gear overhaul: ⑴ damage in the form of gear: A, broken teeth: This is mainly due to improper operation caused by the impact, resulting in a heavy load caused by the material hardening and fatigue caused by tiny cracks and is gradually expanding The reason of broken teeth. B, bad tooth contact: both gears meshing process, not the tooth surface along the tooth length and tooth height direction achieve the required good contact. This phenomenon will cause accelerated wear of tooth surfaces or partial destruction caused by the accident. Causes are two gears meshing center distance or two parallel shaft tolerance, as well as large gear manufacturing error. C, tooth wear: one refers to the long-term normal wear and tear over a certain limit, the other refers to the damage caused by abnormal wear and tear, including adhesive wear, abrasive wear and corrosion and wear. Causes tooth hardness is undesirable, the load is too large and lubricants undesirable. D, tooth surface pitting: both tooth surface pitting fatigue, tooth surface roughness, caused by lubricating unclear. E, plastically deformed teeth: tooth surface quenching hardness uneven (or quenching) is part of permanent deformation soft surface, forming a tooth surface caused by uneven or crooked teeth. Rolling overhaul: In the reducer, the main use of rolling bearings, bearing good and bad working conditions of gear maintenance, directly affects the gearhead performance, life and power consumption. Rolling in the running Symptom: A, the temperature is too high. Bearing normal operating temperature of not higher than the ambient temperature 20oC, the maximum temperature is generally not allowed to exceed the ambient temperature 35oC (ambient temperature to 40oC). When the bearing housing has been hot, indicating temperatures exceeding reducer repair, should open the inspection. The reason is that when the bearing causing fever dirty, oil, oily irregularities maintenance standards reducer, improper assembly, overloading, bearing damage. Murmur. Noise can be checked by auscultation, poor lubrication, bearing partial damage will produce noise. 4, bearing damage: damage to the rolling bearing fatigue spalling, wear gear reducer repair, burns, corrosion and cracking. The reason is: irregularities grease, dirt and oil, but the gap is inappropriate, fit too tight or too loose, bearing specifications improper selection or the load is too large.
