Linear motors are increasingly used in industrial applications to replace the drive device with wear - prone mechanical transmission components.They provide high speed and acceleration, good regulation and accurate positioning.The advantage of linear motor is that the power supplied can be directly converted into linear motion without any intermediate components used in torque conversion machines.Direct - driven linear systems are much more mechanically efficient than rotary - driven systems.In the linear motor system, the only mechanical part required is the linear guide rail.Therefore, the mass of the moving part of the guide device should be kept as small as possible. In addition, the mass of the linear guide rail should be small.Today we will introduce the linear guide
Linear guides are also called line rails, slide rails, linear guides and linear slide rails. They are used for linear reciprocating movement, and can bear certain torque, which can realize high-precision linear motion under high load.In the mainland called linear guide, Taiwan is generally called linear guide, linear slide track.
The linear guide motion is used to support and guide the moving parts to and fro in a given direction.The linear motion guide can be divided into sliding friction guide, rolling friction guide, elastic friction guide and fluid friction guide.Linear bearing is mainly used in automatic machinery, such as machine tools imported from Germany, bending machine, laser welding machine, etc. Of course, linear bearing and straight shaft are used together.Like the linear guide is mainly used in the mechanical structure with high precision requirements, the moving parts and fixed parts of the linear guide do not use intermediate media, but use rolling steel ball.
The linear guide is a precision part, so it is required to be rather cautious in use. Even if the linear guide with high performance is used, if it is not used properly, it cannot achieve the expected performance effect, and it is easy to damage the linear guide.Therefore, the following points should be noted when using the linear guide:
To prevent corrosion
When taking the linear guide rail with the hand directly, the sweat from the hand should be fully washed and applied with high quality mineral oil before the operation, especially in the rainy season and summer.
Keep the environment clean
Keeping the linear guide and its surroundings clean even tiny dust invisible to the naked eye entering the guide will increase wear, vibration and noise.
The linear guide should be careful when used and installed. It is not allowed to press hard. It is not allowed to hit the guide directly with hammer.
Install the tools properly
Use proper and accurate installation tools and use special tools to avoid cloth and short fibers.
