Beli ball screw nut di monotaro.id

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 Nut

Since each row of balls is arranged at a contact angle of 45° so that the same rated load is applied to the LM block in all four directions (radial, reverse radial, and lateral), it is the de facto global standard LM Guide that can be used in any position. The flange of the LM block is tapped, allowing it to be mounted from either the top or bottom. Used when it is not possible to drill through holes for mounting bolts in the table.

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.

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.

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

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.).

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.

Heavy Load Ball Type Linear GuidewayHG series linear guideways are designed with load capacity and rigidity higher than other similar products with circular-arc groove and structure optimization. It features equal load ratings in the radial, reverse radial and lateral directions, and self-aligning to absorb installation-error. Thus, HIWIN HG series linear guideways can achieve a long life with high speed, high accuracy and smooth linear motion.

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.

Balls roll in four rows of raceways precision-ground on an LM rail and an LM block, and endplates incorporated in the LM block allow the balls to circulate. Since retainer plates hold the balls, they do not fall off even if the LM rail is pulled out (except mod els HSR 8, 10 and 12). Each row of balls is placed at a contact angle of 45° so that the rated loads applied to the LM block are uniform in the four directions (radial, reverse radial and lateral directions), enabling the LM Guide to be used in all orientations. In addition, the LM block can receive a well-balanced preload, increasing the rigidity in the four directions while maintaining a constant, low friction coeffi cient. With the low sectional height and the high rigidity design of the LM block, this model achieves highly ac curate and stable straight motion. [4-way Equal Load]Each row of balls is placed at a contact angle of 45° so that the rated loads applied to the LM block are uniform in the four directions (radial, reverse radial and lateral directions), enabling the LM Guide to be used in all orientations and in extensive applications. [High Rigidity Type]Since balls are arranged in four rows in a well-balanced manner, a large preload can be applied and the rigidity in four directions can easily be increased. [Self-adjustment Capability]The self-adjustment capability through front-to-front configuration of THK’s unique circular-arc grooves (DF set) enables a mounting error to be absorbed even under a preload, thus to achieve highly accurate, smooth straight motion. [High Durability]Even under a preload or excessive biased load, differential slip of balls does not occur. As a result, smooth motion, high wear resistance, and long-term maintenance of accuracy are achieved. [Stainless Steel Type also Available] A special type which LM block, LM rail and balls are made of stainless steel is also available.
