The reliability of the rolling linear guide pair refers to the ability of the product to complete the specified function within the specified time and under the specified conditions. These “three regulations” are the core of the reliability concept.
According to the concept of reliability, reliability is a capability, so in order to characterize the reliability characteristics of products and evaluate the level of product reliability, it is necessary to introduce some basic functions for understanding reliability.
So, what is the reliability index of the rolling linear guide pair? Let’s take a look together.
1. Product life, it refers to the workload of the product from the beginning of work to the time of failure, which is generally measured by factors such as working time, number of cycles, running mileage and so on.
2. Reliability function. Reliability is a parameter for quantitative evaluation of reliability using a probabilistic method, and is a probability measure of reliability. It is defined as the probability that a product will perform a specified function under a specified condition and within a specified time.
3. The mean time between failures refers to the ratio of the cumulative working time of the product in the total use phase to the total number of failures under the specified conditions and within the specified time.
For the by-products of rolling linear guides, improving reliability depends on the materials and processing technology, lubrication performance, and installation and use methods.
