[Technical Information] About the Principle of Loosening: Basic Edition

[Technical Information] About the Principle of Loosening: Basic Edition

A detailed explanation of "non-rotational looseness of the threaded part" and "looseness due to rotation of the threaded part"!

When physically defining the loosening of bolts and nuts, it can be defined as "the decrease in fastening force (bolt axial force)." So, what factors contribute to this decrease in fastening force? They can be broadly divided into two categories: "loosening due to non-rotation of the threaded part" and "loosening due to rotation of the threaded part." When considering methods to prevent loosening, it is necessary to examine these two factors. In the products of Hard Lock Industries, development focuses on how to prevent loosening caused by the rotation of the threads, resulting in overwhelmingly superior anti-loosening characteristics. [External force factors for loosening due to thread rotation] 1. Axial direction of the bolt 2. Direction perpendicular to the bolt axis 3. Direction around the bolt axis *For more details, please refer to the PDF materials or feel free to contact us.

[Technical Information] How to detect looseness? (NAS Test)

[Technical Information] How to detect looseness? (NAS Test)

Testing that emphasizes the effects of accelerated (decelerated) environments and high-temperature environments! Introducing NAS testing!

The NAS test refers to the accelerated vibration test described in the U.S. aerospace standards: NAS (NATIONAL AEROSPACE STANDARD) 3350/3354, which is commonly known as the NAS test. Since the test is based on requirements for the aircraft industry, it emphasizes the effects of acceleration (deceleration) environments and high-temperature conditions. At Hard Rock Industries, the "impact vibration test in accordance with NAS3350/3354" is referred to as the NAS test. Additionally, the U.S. aerospace standards specify that the materials for applicable bolts and nuts are primarily heat-resistant alloys, and the lubricants used are also specified, along with various other criteria. To properly conduct the NAS test, it is necessary to adhere to all of these standards; however, for products intended for the Japanese market, tests that conform to the NAS test are generally conducted. *For more details, please refer to the PDF document or feel free to contact us.*

[Technical Information] How to detect looseness? (Yunker Test)

[Technical Information] How to detect looseness? (Yunker Test)

Continuously measure changes in axial force! We will explain the principles of the Juncker test in detail!

The Junker axial perpendicular vibration test is a test for the loosening of screws caused by repeated loads in the axial perpendicular direction. The principle of the Junker test is illustrated in the left diagram. By applying repeated forces perpendicular to the axis of the screw, it generates a loosening torque, allowing for continuous measurement of changes in axial force. In actual usage scenarios of screws and bolts, vibrations occur regularly and are a primary cause of loosening. The Junker test machine artificially generates vibrations in the axial perpendicular direction, which are prone to cause a decrease in axial force, for observation and verification. *For more details, please refer to the PDF document or feel free to contact us.*

[Technical Information] Basic Knowledge of Understanding Looseness: What is Torque and Axial Force Management?

[Technical Information] Basic Knowledge of Understanding Looseness: What is Torque and Axial Force Management?

How to determine the necessary tightening torque to manage the appropriate axial force! Introducing a simple calculation formula.

When fixing the joined components, the types of fastening screws include bolts and nuts. Axial force refers to the force that pulls the bolt in the axial direction when the bolt is tightened, causing the bolt tightening area to stretch slightly. The reactive force that attempts to return to its original state during this process is the axial force. If the axial force is not within the appropriate range, it can lead to loosening or cause the joined components to break, making daily management of proper tightening torque and axial force crucial. Now, to determine the necessary tightening torque for managing the appropriate axial force, it can be calculated using a simple formula. We provide detailed information on this in our technical information site "Screw Fastening Technology Navi," which contributes to solving screw fastening challenges, so please check it out through the related link. *For more details, please feel free to contact us.

[Technical Information] Principle of Inclined Plane (in the case of a screw)

[Technical Information] Principle of Inclined Plane (in the case of a screw)

We will solve various issues related to agreements together with our users! Here, we introduce the principle of slopes in the case of angle screws.

In the tightening of screws, when torque is applied to the nut while the bolt is under axial force, the relationship between the bolt axial force and the torque applied to the nut is derived as an application of the "principle of the inclined plane." On our technical information site "Screw Fastening Technology Navi," which contributes to solving issues related to screw fastening, we provide detailed explanations of the principle of the inclined plane in the case of square screws, using diagrams and other materials. Please take a look from the related links. *For more details, feel free to contact us.

THK Change Nut DCMA Type / DCMB Type

Lead screw suitable for fast-forward mechanism.

The Change Nut DCMA type/DCMB type is a change nut with a lead angle of 45° that is not easily obtained through machining. It can efficiently convert linear motion to rotary motion and rotary motion to linear motion at a rate of 70%, and due to its large lead, it is ideal for creating fast feed mechanisms at low rotational speeds. The multi-start screw shafts that are combined with the change nut are formed through cold forging. The surface hardness of the tooth profile is processed to over 250HV, and with a mirror finish, the movement combined with the change nut is extremely smooth and has excellent wear resistance. Additionally, the DCMA40 type and DCMB40 type or higher are combined with cutting screw shafts. The miniature change nut is molded from oil-impregnated plastic, which provides wear resistance and particularly excellent lubrication performance without oil. Moreover, it can maintain this performance for a long time, making it possible to be maintenance-free. For more details, please contact us.
