the same linear module we use machinery industry is also a reason, the influence of the key parts not only affect our overall work, also affect the the quality of our products and finished products. This is very important in the enterprise, is also very dirty. Then the major problems affecting linear module is what? Help you find a few key factors, discuss together.
1. Precision perseverance: refers to keep original geometric accuracy in the process of work ability. The precision of the linear module perseverance depends mainly on rail abrasion resistance is dimensional stability. Abrasion resistance and guide of data matching, mechanical, machining accuracy, lubrication way and the protective device performance factors. Guide and support within the residual stress can affect the precision of the slideway perseverance.
2. Movement stability module running smoothness is guide rail not appear when trace move in slow motion or the performance of the crawling phenomenon. Stability and linear guide rail structure, guide material matching, lubrication condition and characteristic of lubricant and rigidity of transmission system of the movement of guide rail and other factors.
3. Sensitivity and positioning precision linear guide motion sensitivity refers to motion artifacts can achieve the minimum travel; Positioning accuracy refers to motion artifacts will be effected according to the require the ability to stop at the specified position. Motion sensitivity and positioning accuracy and guide rail type, friction characteristics, movement speed, transmission stiffness, component quality and other factors.
4. Guidance precision and gear coupling and the thermal deformation of bearing parts, etc. Guidance accuracy refers to motion artifacts when moving along the guide rail guide face its trajectory accurately. The main factors influencing the guide accuracy have guide bearing the structure of the guide surface geometric accuracy and guide rail type, guide the contact accuracy, surface roughness, linear guide rail and the rigidity of the supporting members, guide the oil film thickness and oil film stiffness. The geometry precision of linear motion guide generally includes: vertical plane and horizontal plane straightness; Parallelism between the two guide surface. Guide rail geometric accuracy can be used on the guide rail length error or on unit length of said.
5. Stiffness for precision machinery and instrument is particularly important. Linear deformation gear coupling including the guide rail deformation guide contact deformation of ontology, guide's ability to fight stress deformation. The relative position between the deformation will affect the components and guidance accuracy. Both should be considered.
6. Vibration resistance and stability: stability refers to the operation conditions do not appear in a given the performance of the self-excited vibration; And vibration resistance is refers to the module vice forced vibration and shocks.
In an age when electric motor suppliers is increasingly important, the researchers believe manufacturers should pay close attention to their results.
Hangzhou Xiaoshan Zhenyu Transmission Co., Ltd., to be the world leader in products, services and solutions that enable and transform the way consumers and businesses gather, manage, distribute and communicate information.
electric motor suppliers can be great additions to companies looking to improve the well-being of their employees, as well as increase the efficiency and productivity of their workers across the organization.
