Dongyouda Linear Module Factory introduces the application of linear guide shafts in the machine tool industry.

Linear module manufacturers introduce the application of linear guide shafts in the machine tool industry. Linear guide shafts, also known as slide rails, linear motion shafts, or linear rails, are typically used in linear reciprocating motion applications. They have a higher rated load than linear bearings and can withstand a certain amount of torque, enabling high-precision linear motion under high loads. The main function of linear guide shafts is to support and guide moving components, such as servo electric cylinders that perform reciprocating linear motion in a given direction. Based on the nature of friction, linear motion linear guide shafts can be further subdivided into sliding friction linear guide shafts, rolling friction linear guide shafts, elastic friction linear guide shafts, and fluid friction linear guide shafts. Linear guide shafts are widely used in the daily lives of many businesses, such as in sliding door tracks and train tracks. They can also be used in any machine or equipment requiring sliding, such as elevator linear guide shafts, linear motors, and sometimes curtains. Common linear guide rail combination methods: 1) Triangle and rectangle combination: The linear module manufacturer introduces this combination method with triangular linear guide rail as the guide surface, which has a high guiding accuracy coefficient, while the parallel guide rail has better process performance, so it is widely used. This combination has two methods: V-flat combination and edge-flat combination. V-flat combination guide rail is easy to store lubricating oil and can be used at low and high speeds; edge-flat combination linear guide rail cannot store lubricating oil, and the miniature electric steel is limited to low-speed movement operation. In order to make the linear guide rail movement more convenient and effortless and the two guide rails wear evenly, the drive element is generally set below the triangular guide rail or biased towards the triangular guide rail. (2) Rectangle and rectangle combination: The bearing surface and the guide surface are separated, which makes manufacturing and adjustment easier. The gap of the guide surface is adjusted by the inlay, and the contact stiffness is low. (3) Double triangular guide rail: Due to the use of symmetrical structure, the two linear guide rails wear evenly and the symmetrical position remains unchanged after wear, so the single-axis arm is less affected by the machining accuracy. It has considerable contact stiffness and high guiding accuracy, but its processability is poor. It is difficult to make complete contact when the four surfaces are scraped or ground. If the moving parts of the orthogonal robot have different thermal deformations, it cannot guarantee that the four surfaces will contact at the same time. Therefore, it is not suitable for occasions with large temperature changes.
