THK Linear Actuator

LM guide actuator is a compact actuator with high rigidity and precision, which integrates LM guide and ball screw. Using LM actuator can reduce the number of parts and design time.

 

Structure and Features

The LM guidance actuator model KR achieves a highly rigid and precise actuator in the minimum space, as the overall structure of the LM guidance actuator consists of a highly rigid outer rail and a u-shaped cross section, and its two side LM guidance units and a central ball screw unit. In addition, since housing A and B also serve as supporting units and internal blocks serve as tables, this model allows for A significant reduction in the time required for design and assembly, thus helping to reduce overall costs.

 

[4-way Equal Load]

Arrange the contact Angle is 45 ball every line of the rated load of the internal piece of uniformly distributed load applied to the internal block in the four directions (radial, reverse the radial and transverse direction). Therefore, the KR model can be used in any installation direction.

[High Rigidity]The use of a u-shaped section of the outer rail increases the torque and torsion stiffness.

[High Accuracy] As the linear guide is composed of 4 rows of arc grooves, the ball can move smoothly even under preloading, so a highly rigid and seamless guide is realized. In addition, the load fluctuation caused by the change of friction resistance is minimal, making the system track high-precision feed.

[Space Saving] The inlays at both ends of the LM guidance unit and the central ball screw unit make the KR model a highly rigid and highly precise actuator in the minimum space.


[Seal] Model KR has a standard dust seal tail and side seal.

LM Guide Unit

Model KR is capable of receiving loads in four directions (radial, reverse radial and transverse). Its basic load rating is equal in four directions (radial, reverse radial and lateral).

 

Ball Screw Unit

The model KR is able to withstand axial loads due to the combination of the inlays with the ball screw nut. 


Bearing Unit (Fixed Side)

Since the housing A contains an Angle bearing, the model KR can accept an axial load from A.

The LM actuator KR model consists of LM guidance, ball screw and support bearing. Static safety factor and service life of each component can be obtained according to the basic load rating shown in "model KR rated load".


*LM Guide Unit

To calculate the load of the LM guide of model KR, you must first obtain the average load required to calculate the service life and the maximum load required to calculate the static security coefficient.In particular, if the system starts and stops frequently, or if a large torque due to excessive load is applied to the system, the system may receive an unexpected large load. When selecting the model number, ensure that the desired model receives the maximum load (whether static or moving) required.


*Ball Screw Unit/Bearing Unit(Fixed Side)

When the KR model is at rest or running, it is necessary to consider static safety factors when an unexpected force is applied along the axis due to the inertia generated by collisions or starts and stops.
