Basic functions of linear guides and precautions for installation and operation
The market of linear guides is very good today. Its working principle can be understood as a kind of rolling guide, which is an infinite rolling cycle of steel balls between the slider and the guide rail, so that the load platform can easily move linearly with high precision along the guide rail. And the friction coefficient is reduced to one-fifth of the ordinary traditional sliding guide, which can easily achieve high positioning accuracy.
Linear guides, also known as line guides, slide rails, linear guide rails, and linear slide rails, are used in linear reciprocating motion applications. They have a higher rated load than linear bearings, and can bear a certain torque at the same time. Precision linear motion. In the mainland, it is called a linear guide, and in Taiwan, it is generally called a linear guide and a linear slide.
Linear guides are very common in industrial applications and have the following three basic functions:
(1) Guide the movement of the carrier
(2) A moving surface that provides lubrication to the carrier
(3) The force generated by the movement of the train or the cutting of the machine tool is transmitted to the foundation or the bed to reduce the impact of the resulting impact on the carrier and the forced machining of the whole machine.
Linear guides are high-precision accessories. When installing and applying, you must be very careful to avoid unevenness around them and reduce the precision. If the machine needs to change the guide rail, it needs to be done by professionals. So what are the skills for the installation of linear guides?
When installing, first cover the surrounding screws, not too fast or too slow, and fasten them at the same time. If a single screw cannot be tightened, if the balance of the linear guide is inclined, it will cause various problems, the dimensional accuracy cannot be guaranteed, and there are some deviations. To avoid this situation, make sure to install it in the correct way.
