Luggage compartments in the aircraft cabin are usually located above the heads of seated passengers. To ensure optimum headroom between luggage compartments on the one hand, and to facilitate loading on the other hand, aircraft luggage racks can be lowered from shell luggage compartments or trays in certain applications. When lowered, the front of the luggage compartment opens for loading. A luggage compartment with a lowered housing for an aircraft, wherein the lowered housing is connected to a pulley attached to a support structure of the aircraft by a cable. In order to lower the shell, when the rope lifts the shell on the pulley, the rope is released from the pulley, in which the pulley is biased by the force of the power spring along the rotation direction of the rope wound on the pulley. The power assistance for the pivoting of the luggage cover is realized as a spring device. This solution can achieve low maintenance and wear-free equipment in every case.   The natural tendency to expand of the power spring imparts a moment to the arbor or case, resulting in usable torque. The torque produced is cumulative, so the torque increases as the spring is tightened and decreases as the spring is loosened. Power springs that can be assembled into the customer's housing for immediate assembly, or a retaining ring is provided for transferring the spring into the customer's housing. Power spring torque and total turns are the most important output requirements in power spring design. The performance of a power spring depends on the size of the spring material (thickness, width and length) and available space (housing and mandrel...

[Qianye 精度] 8 段階の定荷重ばね設計

時間:2022-9-15

 The constant force spring is made of stainless steel strip. The high-strength steel strip is shaped by specific spring production equipment. When it is straightened by external force, the spring will naturally roll back and produce elastic force. However, when our goal is achieved, it can return to the starting point specified by us after displacement. Constant force spring has the characteristic of maintaining constant force in long stroke, and can be applied to products requiring linear movement such as round-trip, sliding, stretching, homing, balancing or labor-saving. For example, we go to the common fan lifting, store display shelves, tape measure, lifting doors and windows and computer monitor lifting. So if you choose a constant force spring suitable for your product, the design has the following 8 steps. 1. Material selection - most flat steel springs produced by Qianye precision are made of type 301 stainless steel. This material is the most readily available and predictable. Thousands of industry engineers can assist in selecting standard sizes to speed up the process. 2. Estimated life cycle - the life of constant force spring is very predictable, making it one of the most important considerations. Being realistic is important because it is estimated that a longer life cycle will lead to larger and more expensive designs. Underestimating the life cycle of constant force springs may lead to premature failure. Common life cycles range from 4000 to about 25000 life cycles. If a longer life cycle is required, the tolerance of increasing spring diameter and force due to low stress levels and small differences in materials...

工業用ドアへのスプリングの適用

時間:2022-9-3

  The constant force spring of the industrial door mainly plays a balancing role and reduces the burden on the motor. The force of the spring is equivalent to the force of the industrial door, which is the most ideal configuration state. If the spring force is too large or too small, it will affect the operation of the industrial door. In severe cases, safety accidents may occur and endanger others.        Constant force springs are often used to provide balance to products, so what is balance?        Constant force springs are most useful in applications that require consistent recoil. Ordinary springs behave according to a mathematical equation called Hooke's law. Hooke's law states that the force of a recoil spring in the direction of recoil is equal to the distance the spring is displaced from equilibrium. Simply put, we look at how far the spring is stretched - multiplied by a mathematical constant, the rate of the spring. The recoil direction of the spring is opposite to the stretch direction.        Hooke's Law does not affect constant force springs because their recoil remains constant throughout their range of motion. Their unique design consists of a thin, coiled steel strip that rests when fully coiled. Constant force springs are loaded when they are partially or fully deployed. When released, the spring springs back, pulling the extended ribbon back and rolling up properly. Since the recoil force is mainly obtained closest to the take-up roll, a constant force is maintained. A constant force spring can be...

The variable force springs can break through the traditional spring affected by Hooke ' s law, so that the stroke and force are no longer proportional to increase, but can achieve a variety of elastic displacement combinations such as negative slope stepped fixed force. According to the needs of mechanical engineering, the relationship between elastic force and displacement stroke can be used to design various elastic curve changes in specific occasions, which is the output force value can be arbitrarily desired.     The variable force springs can be customized for various elastic curve changes according to specific occasions, such as department store shelves propulsion device, pen-type drug syringe ( insulin ) and cordless curtain.      What are the reasons for using variable force springs in these applications ? What are they trying to achieve ?     In the point of purchase display, variable force springs are commonly used in trays that push product forward in a controlled manner. Variable force spring corporated into pusher trays aid in front-facing the product, allowing shelves to look stocked at all times. These trays allow for a more organized store inventory, as well as assist in keeping track of inventory needs. Variable Force springs are designed around the weight of the products they are pushing. This means that they are always designed in a way where the product never gets slammed or compromised while being selected. These springs allow for most any product to be pushed consistently, regardless of the weight.  Allow for the product to be shopped hassle–free by the customer. Products include cosmetics, health/medicines, beverage, food and much...

Fireplaces are freestanding or wall-mounted indoor heating devices, powered by combustible materials, with internal chimneys, originating from Western homes or palace heating facilities. Because its fuel is a renewable resource, modernized and improved, it is still commonly used in the West, and is especially popular among the higher education class, which advocates environmental protection. Fireplaces can also be installed in ordinary homes, and are perfectly achievable for small flats. The fireplace in modern homes is certainly not the firewood burning in the living room of a large villa that we see in the movies and TV, burning a fire and emitting the sound of a "blazing" star.   In colder climates, the fireplace has always been the main feature of a home, as it gives people warmth to survive the long winter hands. The feeling of warmth from the baking, and the jumping and flickering flames, even today, still make people feel happy in cold weather. The warmth of a fireplace is incomparable to that of an air conditioner, and I'm not talking about the psychological effect, which is in fact the case. Compared to air conditioners, fireplaces heat up quickly and the warmth of a real fire is comforting and relaxing. The variable force springs used in the fireplace up-down sliding doors because when the door is closed, the spring force is less than the weight of door; while the door in middle stroke, the spring force is equal to the door weight. When fully open, the spring exerts force greater than the door weight to secure the door does not...

Do you know how clockwork toys work?

Time:2023-3-6

Clockwork toys use constant torsion springs made of stainless steel coils. An external force rewinds the spring to the output wheel (energy storage) from its natural state. When the force is removed, the spring returns to its natural state. At the same time, a constant torque (stored elasticity) is generated (released) at the output wheel, hence the term constant torque spring. The torque is greatest when the barrel is fully wound so that the front end of the barrel needs to be output with less force. After a certain period of time, the winder, which is tightly coiled on the winding shaft, will slowly unwind and its energy will drop. When the energy is about to be exhausted, the torque at the end of the barrel is at its minimum and the force output is then reduced. Thus, the driving force needs to be increased to keep the movement running. This is why constant torque springs are so suitable for wind-up toys.

【銭業精度】定荷重ばねの物理設計と反動力

時間:2022-9-15

 ほとんどの種類のばねでは、ばねが圧縮されてから弛緩すると、加えられる力はばねが伸びる距離に比例します。通常のばねとは異なり、定荷重ばねはこの規則に準拠していません。コンスタント フォース スプリングの物理的な設計により、その戻り力は一定のままです。したがって、コンスタント フォース スプリングは、一貫した反動を必要とする多くのアプリケーションで役立ちます。通常のばねの挙動は、フックの法則と呼ばれる数式で記述できます。この法則は、リコイル スプリングの反動方向の力は、スプリングの変位と平衡点の間の距離に等しいことを示しています。つまり、バネがどれだけ伸びて、数学的な定数、つまりバネの剛性が掛けられているかということです。スプリングは伸びた方向と反対の方向に戻ります。多くの弾性材料がこのように機能するため、フックの法則は物理学の分野で幅広い用途があります。コンスタント フォース スプリングにはフックの法則は適用されません。これは、薄くカールしたスチールストリップで構成される独自の物理設計によって実現されています。コンスタント フォース スプリングは、完全に巻き上げると弛緩状態になり、部分的または完全に広げると負荷がかかります。リリース後、伸びたカーボンベルトをタイトなコイルに引き戻すことでスプリングがリバウンドします。反動力は主にコイリングロールに最も近い部分から発生するため、一定の力を維持できます。一定の力の一般的な用途...
