37 Assembly manual 1. V track bearing match carriage plate Please mount the concentric bearing to one side of carriage plate, and eccentric bearing to the other side following the direction of railway. In case of ring type carriage, the concentric bearing should be mounted to the side where mounting-hole distance is shorter. Please refer to below picture. For concentric bearing For eccentric bearing ircle motion carriage plate 2. Mounting to railway arriage assembly should be mounted from the end of railway.please do not put any overstress when mounting. 3. Adjust the clearance between bearing and railway -Tighten concentric bearings first. -Then rotate eccentric bearing via rotate hexagonal key at the end of stud to adjust the clearance between railway and bearing. -Adjust the clearance to zero. -Slide the carriage by hand and adjust to the extent where there causes a slight slipping resistance. orrect condition is where moving power becomes the recommended value as below table by putting load by push-pull gauge to the running direction of carriage. Recommended pre-load by push-pull gauge V track bearing size Pre-load(N) Keep eccentric bearing's position and tighten the nut. Important note Appropriate pre-load provide the system rigidity. However, over preload will decrease system's life rapidly. Please be careful. 33

38 Load / Life calculation Due to the hardness of the railway and fatigue analysis of railway and roller, the railway's life does not determine the system life. It is determined by roller's life. Load capacity of the motion guide system varies mainly by the size of bearing and railway, lubricated or not, and the load magnitude and direction. Other factors include speed and acceleration and environment etc. To calculate system life, loading factor LF should be calculated firstly. Here we provide two methods to calculate the loading factor. Standard 4 bearings carriage calculation If the system use SAIBO standard 4 bearings carriage, then calculation can use below formula. Fy My Mz Fz Mx Fy Fz Mx My LF = Fymax Fzmax Mxmax Mymax Mz Mzmax Fy - Actual load in Y direction. (N) Fz - Actual load in Z direction. (N). Mx - Actual moment in X direction. (N m). My - Actual moment in Y direction. (N m). Mz - Actual moment in Z direction. (N m) Below parameters can be taken from the table of Load capacity. Fy max - Max load capacity in Y direction. (N) Fz max - Max load capacity in Z direction. (N). Mx max - Max moment capacity in X direction. (N m) My max - Max moment capacity in Y direction. (N. m) Mz max - Max moment capacity in Z direction. (N. m) 34

Biggest loaded bearing's load determines the system's life. Fy Fz 35

The basic life can be taken from table below. Dry system Life(km) = Basic_life ( LF*f) 2 Lubricated system Life(km) = Basic_life ( LF*f) 3 Basic_life Bearing type Dry system Lubricated system SVR SVR SVR

41 f - Reduction coefficient of the application and environment. None vibration or shock, Low speed (<1m/s), Low frequency shift direction, clean environment. Light vibration or shock, medium speed (1-2.5m/s) medium frequency shift direction, some dirtiness Heavy vibration or shock, high speed (>2.5m/s) high frequency shift direction, heavy dirty alculation example A machine use SB-LGV25 spacer railway and standard carriage. The carriage and work-piece total weight 8 kg. When the carriage moving, there is an external load of 50 N exerted as below drawing. Working environment is clean. There is none vibration or shock. 50N 8Kg 0.05m The load factor LF is calculated use formula LF = Fy Fymax Fz Mx My Fzmax Mxmax Mymax Mz Mzmax Fy = 8kg x 9.8 (gravity) = N Fz = 50 N. Mx = 50 x 0.05 = 2.5 N m My = 0 Mz = 0 37

42 Take parameters Fy max, Fz max, Mx max, My max, Mz max from table and then fill in the formula LF = Mymax + Mzmax = Then life (km) calculation can use formula as below: Dry system Life(km) = Basic_life ( LF*f) 2 Basic life is 100km. According to the description of working condition, take f=1.3. Life(km) = 100 ( *0.2816*1.3) 2 = 674km Lubricated system Basic life is 150 km, take f=1.1 Life(km) = Basic_life ( LF*f) 3 Life(km) = 150 ( *0.2816*1.1) 3 = 4155km From this example, it shows clearly that lubrication is so important for the life. Please pay attention to install the lubrication system for your system. 38
