Linear Rolling Guide 4. Performance characteristics and application load capacity linear guides with good bearing properties, can withstand forces in different directions and moment loads, such as the ability to withstand vertical and horizontal directions, and bumpy moments, shaking moment and swing torque. Therefore, having a good load adaptability. Proper pre-load in the design and manufacture of the damping may be increased in order to improve the vibration resistance, and can eliminate the high-frequency vibration phenomenon. The slide rails in a direction parallel to the contact surface can withstand lateral load is small, easy to cause adverse machine running accuracy. 5. easy to assemble and interchangeability with the traditional sliding guide rails must be scraping the surface were both cumbersome and time-consuming, and once the bad machine precision linear guides, must Zaigua research once. Rolling guide interchangeable, as long as the slider or the entire rolling guide rail or vice replace linear guide Intime, to regain the high-precision machine tools. As described above, since the balls relative movement between the rolling guide and the slider, to reduce friction losses. Typically rolling friction coefficient of sliding friction coefficient of about 2%, and so the use of rolling guide drive mechanism is far superior to the traditional sliding rails. Linear optical axis function, structural characteristics and technical requirements is one of the typical linear axis machine parts often encountered. It is mainly used to support transmission parts AMT linear guides, transmission torque and load bearing. Linear axis is rotating body parts, its length is greater than the diameter, generally by the outer cylindrical, conical surface, bore and thread and the corresponding end surface composed of concentric shafts. Depending on the shape of the structure, the linear axis can be divided into chrome rods, stepped shaft, hollow shaft and crankshaft. The optical axis is called the short axis aspect ratio less than 5, greater than 20 is called the elongated shaft, the majority of the shaft between the two. Axis with ABBA linear guide bearing, shaft and bearing with a segment called journal. Journal reference axis is assembled, their accuracy and surface quality in general are higher, its main function is generally based on technical requirements and working conditions of the development of the shaft, usually have the following: since (a) the dimensional accuracy of the supporting role of the journal In order to determine the position of the shaft, its size is usually higher accuracy requirements (IT5 ~ IT7). Journal size precision assembly generally require less transmission parts (IT6 ~ IT9). (B) the accuracy of the geometry of the geometry precision linear axis mainly refers to the journal, the outer cone, such as Morse taper roundness, cylindrical, etc., generally should be limited within the tolerance range of dimensional tolerances. For high precision internal and external circular surface, which allows deviations should be marked on the drawings. (C) the mutual position accuracy of the positional accuracy of the linear axis is mainly required by the shaft and the mechanical function of the determined position. Should normally ensure that transmission parts for assembly journal bearing journal of concentricity requirements, otherwise it will affect the transmission parts (gear, etc.) of transmission accuracy and noise. General accuracy of the shaft, which shaft section with radial runout bearing journal is generally 0.01 ~ 0.03mm, high precision axis (spindle) is generally 0.001 ~ 0.005mm.
