PREFACE

THE LINEAR GUIDE RAIL SYSTEM is a kind of rolling guide, which is infinite rolling loop between the slide and the guide rail, and the load platform can easily make linear motion with high precision. Compared with the traditional sliding guide, the friction coefficient of the rolling guide can be reduced to 1/50 of the original. Because the starting friction is greatly reduced, relatively less ineffective motion occurs, so it can easily reach \upmu m level feed and positioning. In addition, the design of the beam making unit between the slider and the guide rail makes the linear guide rail can bear the load of the upper, lower, left and right directions at the same time. The above display characteristics are not comparable to the traditional sliding guide. Therefore, if the machine can cooperate with the ball screw and use the linear guide rail as the guide, the accuracy and mechanical efficiency of the equipment will be greatly improved.

1-4 Rated load

1-4-1 Basic static rated load

(1)Definition of basic dynamic rated load (CO)

If the linear guide bears too much load during rest or moving, the contact surface and the local permanent deformation will exceed a certain limit, which will prevent the smoothness of the linear guide movement. The basic static rated load is the limit load allowed for this permanent deformation. According to the definition: when the direction and size of the load remain the same, the total permanent deformation of the steel bead and the surface of the bead path is the static load at 1/10,000 ofthediameterofthesteelbead.

The value of basic static rated load is detailed in the table of each specifications; users can select suitable linear guide, but it must be noted that the maximum static load of the selected linear guide in operation shall not exceed the basic static ratedload.

(2)Definition of the allowable static moment (MO)

When the maximum stress in the slider reaches the static rated load defined above, the moment carried by the slider is called thestaticrated moment.Inthelinearrail movement,MR,MPandMYaredefined:

(3)Static safety factor

When the linear guide rail is used in slow motion or low movement frequency, the static safety factor should be considered. According to the different use conditions, the calculation of the static load must be considered with different safety factors,especially when the guide rail is affected by the impact load, the need to use a larger safety factor.

1-4-2 Basic dynamic-rated load

(1)Definition of basic dynamic load (C)

The basic dynamic rated load is used for the life calculation when the linear guide rail bears the load and makes the rolling movement. It is defined as the maximum load when the rated life of the linear rail is 50\mathsf{k m} undertheconstantdirectionand sizeoftheload (100k m for the roller linear rail). This value is detailed in the size table of each specification. The user can estimatetherated lifeof theselected linearrail inadvance.

1-5 Linear guide rail life

1-5-1 life span

When the linear guide rail bears the load and moves, the surface of the bead path and the steel bead are constantly subjected to the cyclic stress.Once it reaches the criticalvalue of rollingfatigue,the contact surface will begin toproduce fatigue damage, and the peeling phenomenon of fish scale sheet occurs on part of the surface. This phenomenon is called surface stripping. Life is defined as the total operating distance between the surface of the bead path and the steel bead due tomaterialfatigue.

1-5-2 Rated life span

The life of the linear guide is very dispersed, even in the same batch; this is mostly attributed to the inherent change in the fatigue characteristics of the material itself. Therefore, to define the life of the linear rail,the rated life is generally used; it is defined as the same products operating under the same conditions and rated load, of which 90% ofthetotaloperating distance can be achieved without surface stripping.

1-5-3 Lifetime calculation

The life of the linear guide rail will vary according to the actual working load, and the service life can be calculated according to the basic dynamic rated load and workingload of the selected linear guiderail.

gardless of environmental factors,thelife span calculation is show

L :rated life span
C :Basic dynamic rated load
P:working load

(2)If the environmental factors used by the linear guide rail are considered, its life will change with the moving state, the surface hardness of the bead path and the system temperature.

L=((\rho_{\mathsf{h}}*\rho_{\mathsf{t}}* C)/(\rho_{\mathsf{w)}* P_{\mathsf{c}}}\ )^{s*50k m=((\rho_{\mathsf{h}}*\rho_{\mathsf{t}}* C)/(\rho_{\mathsf{w)}* P_{\mathsf{c}}}\ )^{s}*31m\mathsf{i}\verte}

\mathsf{f}_{\mathsf{h}} :Coefficient of hardness
C:Basic dynamic rated load
\boldsymbol{\mathsf{f}}_{\mathfrak{t}} :Temperature coefficient
\mathsf{P}_{c} :Working load
\boldsymbol{\mathsf{f}}_{w} :Load factor

1-5-4 lifetime coefficient

(1)Hardness coefficient (f_{\mathfrak{h}})

The hardness of the bead path contact surface of the linear rail should be HRC 58\~62 at a certain hardening depth. If the hardness value cannot reach the required level, the rated load and service life of the linear rail will be reduced. At this time, the dynamic and static rated load is the size table value and then multiplied by the corresponding hardness coefficient. The hardness of straight rail of JSM is aboveHRC58,sofh is 1.

(2)Temperature coefficient (ft)

The temperature of the system will have animpact on the materialof the linearrail.When the temperature is higher than 100°C_{i} therated load and service life of the linear rail will bereduced.At this time,the dynamic and static rated load is the size table and multiplied by the corresponding temperature coefficient. Because some accessories are plastic material is not resistant tohightemperature, so it is recommended that the use temperature should belower than 100°C

Temperature

(3)Load coefficient (fw)

Function on the linear rail load, in addition to the device itself weight, stop the inertia load and the suspension from the load, and movement with vibration and impact load, this type of load is not easy to calculate, according to the load condition and use speed, it is recommended to calculate the load value multiplied by the corresponding load coefficient.

1-5-5 Conversion of the lifetime time

The life distance is converted to the life time according to the service speed and frequency.

1-6 Workload

1-6-1 Workload calculation

Work load calculation method will change with the actual force distribution situation, such as the position of the center of gravity, the force position, and running start, stop the acceleration of inertia force affect the load calculation, so the use of linear rail must carefully consider all kinds of load condition, to calculate the most correct load value.

(1) Inertial force load

Table4.Exampleof inertialforceloadcalculation

(2) A single slider to bear the load

1-6-2 Mean load calculation

In operation, the load of the slider is sometimes not equal., for example, in the operation of the delivery device, it bears the extra weight of the goods when advancing, and only bears the weight of the device itself when returning. The load presents a step change. Therefore, the average load in operation must be calculated to calculate the life. The average load is defined as an equivalent load value equal to the life under load changes.

3 Equivalent load calculation in both direc

The linear guide can bear the upper, lower, left and right direction load, so when using the linear guide, it may be both the vertical direction load (Ps) and the side direction load (Pl), so the equivalent load (Pe) can be converted according to the following formula.

P=Ps+P,

When P,>P, P=P,+0.5·P, When P,>Ps P_{e}{=}P_{l}{+}0.5* P_{s}

1-6-4 Example of service life of linear rail

According to the experience, the type and specifications of the linear guide rail are selected, and then the maximum working load of a single slider is estimated according to the actual use situation, and the load ratio between the dynamic rated load and the working load is calculated to calculate its service life.

1-7 Friction force

The linear guide is guided by steel beads, so the friction can be reduced to 1/ 50 of the traditional sliding guide, especially the static friction is very small, and there is no big difference between the dynamic friction, so the phenomenon of idling slip and the micron motion accuracy; generally speaking, the friction coefficient of the linear guide is about 0.oo4. The resistance of the oil scrapervaries according to different specifications,and its value is listed in thefriction section of each specification

F :friction force (kN) μ:Friction force coefficient S :Scrapper resistance(kN) W :Movement vertical direction load(kN)

If the linear guide is not properly lubrication, the friction of the rolling part will increase, and long-term use will become the main reason for shortening the life. Lubricant provides the following effects:

⊚ Reduce friction in the rolling part, prevent burns, and reduce wear.
⊚ Oil film is formed between the rolling surface, which can prolong the rolling fatigue life.
⊚ Preventrust.

1-8-1 Lube oil grease

Each group of straight guide rail should lubricate the bead groove track. Although the lubricating grease is not easy to lose,in order to avoid insufficient lubrication caused by lubrication loss, it is suggested that the lubricating grease is 100~\mathsf{k m} again. At this time, the oil injection gun can be used by the oil nozzle attached to attach the slider to push the oil into the slider. Lubricating grease is suitable for situations where the speed does not exceed 60m / min and has no cooling requirement

T :Injection frequency(hour) \mathsf{V_{e}} :velocity(m/min)

1-8-2 Lubricating oil

It isrecommended that the customer uselubricating oilwithoilviscosityabout 32~150 cst.JSMcaninstallthetubing connector at the original location of the nozzle as the customer needs, so the customer only needs to connect the preset tubing to the tubing connector. The loss of lubricating oil is faster than that of lubricating oil, and attention must be paid to whether the oil supply is sufficient when using. If the lubrication is insufficient, the abnormal wear of the linear guide rail can reduce itslife.It isrecommended that the oil drillingfrequencyis about 0.3\mathsf{cm}\mathsf{3} /hr,andcustomerscanuseitaccordingto their use conditions.Lubricating oil is suitable for various loads and speed occasions, but it is not suitable for high temperaturelubrication.

2-1-11 Notes for installation

(1)lnstall the face with the shoulder heiqht and chamfer

When installing the linear guide rail, we mustpay attention towhether the condition of the shoulder of the installationsurface is appropriate. If the chamfering is too large, the protruding place is easy to cause the poor accuracy of the linear guiderail，and if the height is too high, it will interfere with the slider.Therefore,if the surfaceand shoulder canbeinstalled accordingto therecommended requirements，the poor installation accuracy canbe eliminated.

(2)Torsion force value of the guide rail assembly screw

Whether the installation of the guide rail is close to the flat datum affects the accuracy of the straight guide rail, so in order to achieve the purpose of locking each screw, it is recommended to use the following torsion value lock to assemble the screw.

2-1-12 Standard length and maximum length of a single guide rail

We have a guide rail standard length inventory to supply customer demand. If the customer orders the non-standard length rail, the size of the end face distance E should not be greater than 1/ 2P, so as to prevent the instability of the rear endoftherailassemblyandreducetheprecisionofthelinearrail.
