"Diligence" Do you know why [] textile machinery gear fail it?
In the course of textile machinery in gear, you often encounter the situation of textile machinery gear failure? If so, you know that one of the reasons for it? Today we will look together several possible reasons for textile machinery gear failure.
First, if the gear is imported, then we see from the wear, the failure may be due to tightness is not good enough, some of the hard particles into the lubricant, the meshing of motion, resulting in loss of tooth surface material dislocation; Further at the time of installation, mounting accuracy if not well controlled, can make contact with the tooth surface accuracy is poor, over time, destroy the smoothness of the surface of the tooth, making the tooth surface hardened metal off, disrupting the normal tooth surface shape, resulting in rapid wear .
So, if the domestic gear from wear situation can be divided into a number of reasons. First, mapping have problems, inappropriate parameters directly affect the life of the gear; second, material selection and heat treatment problems. In theory, we believe that high-speed heavy gear teeth meshing process, if the meshing zone temperature is too high, then the viscosity of the oil is reduced, lubrication will disappear. This will result in direct contact with the tooth surface, and with the relative motion will eventually lead to failure of gluing. Therefore, the material that you choose is not a good scuffing resistance, as well as the size of the gear material Is there a proper combination of hardness and depth of hardened layer of the tooth surface is not suitable, the gear off the surface decarbonization did so a series of factors, seriously affect the life of the gear. Coupled, precision gear problem, an error occurs processing can cause a variety of problems; maintenance must attract attention, if you can not do regular checks on the bad situation to be timely treatment, do not do regular lubricants replacement, which will accelerate the failure of the gear.
