ダウンロード台形ネジ/台形ネジ用の関連部品
台形の歯の形をしており、スクリュートランスミッションの一種です。運動と電力は、ナットとネジの嵌合によって伝達され、回転運動を直線運動に変換します。台形ねじは、高い伝達効率、正確な位置決め、高荷重荷重を特徴としています。
Installation Steps and Maintenance
(1) Installation of Support Components
① Insert the trapezoidal screw into the fixed side support component.
② Temporarily tighten the accompanying fastening nut after inserting the collar. Tighten it to 1/3 of the tightening torque. At this time, the support side support component must be inserted into the support side, fixed, and then work can be carried out.
③ Tighten the nut while rotating the screw shaft to ensure smooth overall operation.
④ Once the overall operation is smooth, fully fix it with the tightening torque.
(2) Installation of Nuts for Screw Rods
① Chamfering of the Support Base
To increase the strength of the flange root of the trapezoidal screw, it is necessary to process the corners into an R shape. Therefore, it is necessary to chamfer the inner corners of the support base.
(3) Recommended Installation Direction
When using the screw rod to convey heavy objects in the vertical direction, it is safe to install the trapezoidal screw as shown in the figure below. This can provide support on the installation hole to prevent the moving object from falling, even if the trapezoidal screw breaks due to overload or impact.

(1) Installation Example
The following figure shows an example of trapezoidal screw installation. When installing the trapezoidal screw, it is necessary to fully ensure the axial fixation strength.
Lubrication
Trapezoidal screws are not coated with lubricating oil or grease when delivered, so it is necessary to provide an appropriate amount of lubricating oil or grease after installing the bearing.
