The cause of Gear fault of the block making machine
Gear is the brick making machine, and other numerous essential parts of machinery and equipment, is the mechanical equipment of power transmission brought the firmware, in daily production gear due to the structure, factors such as different materials, running environment and condition, form of failure is different also, to help the brick machine users better maintenance and repair, sum up the cause of gear fault.
1. Manufacturing errors.
Gear manufacturing errors mainly include eccentricity, tooth spacing deviation and tooth shape error.Eccentricity means that the geometric center and rotation center of the gear do not coincide, tooth pitch deviation means that the actual tooth pitch of the gear and the nominal tooth pitch have a great difference, and tooth shape error means that the involute tooth profile has an error.
2. Improper assembly.
Improper gear assembly will result in deterioration of working condition.When the meshing of the gear shaft uneven, will only one end of the contact in the tooth width direction, or the linear deviation of the gear, so that the gear bears the load in the tooth width direction is not uniform, can not transfer the dynamic torque smoothly, will make the local teeth bear too much load, it is possible to cause tooth breakage.
3. Improper lubrication.
For high speed heavy duty gear, poor lubrication will lead to local overheating of the tooth surface, resulting in color change, glue and other faults.Causes of poor lubrication are various, brick making machine daily use of oil pipe blockage, water in lubricating oil, lubricating oil deterioration will cause poor lubrication teeth.
4. The overload.
For the gear drive device with unstable work load, there will often be overload phenomenon, if there is no appropriate protection measures, it will cause overload fracture of gear teeth, or long-term overload will lead to a large number of gear root fatigue crack, fracture.
5. Misoperation.
Staff errors in the daily operation of cement brick making machine can also lead to gear failure.Usually include lack of oil, overload, long-term overspeed, etc., can cause gear damage, damage.
