EspañolHow to account for the life of the bearing of the copper sleeve? Calculate the life of the copper sleeve bearing, we copper bearings now the thing to do is to calculate its PV value, PV refers to the bearing in a certain load and linear speed conditions of the product of the sum of the PV value and the use of the life of the copper sleeve bearings into a share of the connection. Therefore, the advocacy of the planning time to try to use a lower and safer than the bushing PV value, to ensure that the bearing will have a longer life, although the samples of China has a clear variety of materials PV value, but these are tin bronze bushing is measured in the rotating conditions, and the reality proves that the planning staff in the planning of bronze bushing bearings life time also need to consider a number of factors. In addition, the environmental temperature is also a must refer to the material, due to the rise in temperature caused by the bronze bush bearings and seat between the control of the cooperation gap will change, the shaft and bearing bore cooperation tolerance will also change, these will affect the bronze bush bearings of the final life of the general situation, the life of the bearings we produce are in the 70,000 hours or so, so it is necessary to take good care of the bronze bush bearings. So we should take good care of the brass sleeve bearings.
Some customers will say the use of our products, and did not reach so many hours, why? This is the problem of maintenance. So many moments is our ideal use of the environment measured in practice, the shortfall in the smooth, coupled with the entry of foreign objects, resulting in a high load, will shorten the life. Some customers due to the strength of our experiments can not reach the strength of the use of the moment will be longer, these analogies are numerous, let's take a day in the analogy, let's say the same car, different people drive for three years there will be a different car is not the same, the reason is also the same.
