Causes and Solutions of Unsmooth Rotation of Precision Shaft
Precision shaftWhat is the cause of poor operation? What is the corresponding solution? Today Sanhe Xiaobian will explain to you:
Causes of poor 1. precision axis
1.High precision axle temperature
Precision axes with low accuracy. If the precision of the precision axis is low, the precision of the incorrect precision axis does not meet the reference value, or the choice is different, the machine does not meet the operating conditions, so the precision axis will intuitively generate heat.
2.Dust and pollution
Under normal outdoor equipment and conditions, the precision shaft system has corresponding protection in general,bixuIt will be protected as much as possible to prevent secondary damage caused by sand and dust. In addition, outdoor humidity and humidity can corrode precision shaft parts. If the moisture in the air and particulate pollutants are mixed together, it will cause fatal damage to the precision shaft and further shorten the life of the machine.
3.Power issues
（1) When the voltage is high enough, it will short-circuit and discharge. This regular discharge will corrode the metal, and the speed of the rotor will affect the corrosion. High-speed rotation will form a thick oil film, the higher the voltage, the greater the damage
（2) At low speeds, the oil film will“Contact”Large area, and the risk of damage is much lower. The higher the speed, the higher the power rating and the higher the DC voltage, the greater the risk of damage.
4.Lubrication problems
Lubrication is a necessary condition for the proper operation of the precision shaft. Lubrication has an important influence on the fatigue life, friction, wear and vibration of precision rolling bearings. Precision shaft damage approx.40Points related to poor lubrication. The purpose of precision shaft lubrication is to form an oil film between the rolling surfaces of the precision shaft to avoid direct contact between metal and metal. When the precision shaft is poorly lubricated, it is easy to cause damage and affect the use.
2. to solve the problem of poor operation of the precision shaft
1.high temperature solution
Check whether the pipeline is blocked, whether the oil supply temperature and condensate temperature exceed the standard. If the cooler is not selected correctly, the cooling effect is poor, and it cannot meet the requirements of use, please replace it immediately, or
2.Pollution Solutions
Select the appropriate level of protection. In other words, the floating particles, the corrosive particles, and the conductive particles are protected separately, and the protection efficiency is improved.
3.Solve the problem of insufficient power supply
Poor power supply is mainly due to unstable power supply voltage. What we can do is to stabilize the power supply voltage when the precision axis is working.
4.Solution to poor lubrication
Choose the right grease. During the inspection process, clean the precision shaft box and precision shaft, check the oil supply pipe and make it circulate, and do not mix different types of grease. When replacing other types of grease, clean the original grease first.
