Ball Screw

High efficiency is obtained because the ball rolls between the screw shaft and the nut, and the driving torque becomes 1/3 or less compared with the conventional sliding screw.Therefore it is easy to change not only the rotary motion to the linear motion but also the linear motion to the rotary motion.Due to the rolling motion by the ball, the starting torque is extremely small, and stick-slip does not occur like sliding motion, so accurate fine feed can be performed.Since there is no backlash and preload is given, axial clearance can be reduced to zero or less by preloading, and high rigidity can be obtained. It has high efficiency and low heat generation, so you can fast-cut. Shaft end, finished product is screw shaft and ball screw nut standardized for space saving standard. The screw shaft standardizes the terminal in conformity with the support unit, and it is made to be a direct connection structure with the motor.Screw shaft, ball screw nut shape is compact design.An appropriate amount of grease is sealed in the ball screw nut. When penetration of foreign matter is considered, it is necessary to completely cover the screw shaft with a dustproof device (bellows etc.).

The Rotary Ball Screw is a rotary-nut ball screw unit that has an integrated structure consisting of a ball screw nut and a support bearing. The support bearing is an angular bearing that has a contact angle of 60, contains an increased number of balls and achieves large axial rigidity.

Using an end-cap method, these models achieve stable motion in a high-speed rotation.

It can perform ideal rolling motion while receiving high load and high rigidity equal load in four directions.The LM Guide's automatic adjustment ability provides excellent error absorption capacity and improves precision after assembly.

Ball Screw Nut

The large lead rolled ball screw is provided on the end face of the ball screw nut after rolling motion of the ball rolling surface provided on the screw shaft and ball screw nut with the load ball around the screw shaft while receiving the axial load It is scooped up from the groove with the end cap, circulates through the ball screw nut and reaches the load zone again from the opposite end cap to make infinite rolling motion. The ball rolling surface of the screw shaft is rolled to the right thread, and the ball rolls in the groove. Stable operation is obtained even at high speed rotation, so it is silent as the ball rotates through the ball screw nut. Replacing the standard ball screw at a high speed and replacing it with the location you are using can reduce the rotational speed of the screw shaft, so make the screw shaft diameter thicker in consideration of the critical speed of the screw shaft or use a difficult fixing method for the screw shaft There is no need to adopt it, leading to cost reduction. The ball screw nut has a short length, the outer diameter is also minimized, and the flange is flattened at two places to reduce the core height and is a compact structure. A large rotational force can be obtained with a small thrust, and it is also suitable for actuator etc.Ball screw nut has built-in brush seal with high dust prevention effect.

Ball screw support unit is a bearing connected ball screw and motor, its structure and specialty for standard ball spiral its axis of the inventory the finished product, preparation of the standardization of the support unit EK, EF type, to general ball spiral poles prepared the standard support unit BK, BF type.Support unit EK, BK type of internal bearing load in the right amount of lithium base grease, with the special seal gasket to seal, can direct installation, use for a long time.

3 degree trapezoidal screw. When combined with a die-cast molded screw nut and a high-precision rolled screw shaft, this high-performance feed screw can reduce costs by 5% compared to conventional machined products.

Since the tooth profile of the shaft is Formed by cold rolling, the surface of the tooth surface is work hardened to 250 HV or more, and because it has a smooth mirror finish, it is excellent in abrasion resistance and movement by a combination of nuts is extremely high It is smooth. The internal structure of the tooth surface causes fiber flow along the contour of the tooth profile, the tissue at the root of the tooth is extremely honey, and the fatigue strength is increasing.Useable: Screw nut DCM, DC common

HSR model rails also include a type where the LM rail is tapped from the bottom. This type is useful when mounting from the bottom of the base and when increased contamination protection is desired.

The balls roll on the precision-ground rolling surface, and the ball train is circulated by the end plate incorporated in the LM block. Since each ball row is arranged with a contact angle of 45 degrees so that the Rated load is the same for the four directions (radial direction, reverse radial direction, lateral direction) acting on the LM block, it can be used in any posture. It can be used for a wide range of purposes. Since it is a well-balanced 4-row arrangement, sufficient preload is given, and the rigidity in 4 directions can be increased without difficulty. Due to the effect of the automatic adjustment ability by the front combination (DF set) of the circular arc groove, the mounting error can be absorbed even if preload is applied, and high-precision and smooth linear motion can be obtained. There is no differential slip of the ball against preload or eccentric load, smooth operation is obtained, and excellent wear resistance maintains accuracy for a long period of time. The narrowed width and tapped type are ideal for compact designs.

Since the tooth profile of the shaft is formed by cold rolling, the surface of the tooth surface is processed and hardened to 25 HV or more, and it has a smooth mirror finish, so it has excellent wear resistance and the movement due to the combination of nuts is also extremely high It ’s smooth. In the internal tissue of the tooth surface, fiber flow occurs along the outline of the tooth profile, the tissue of the root part becomes extremely nectar, and fatigue strength is increased.
