Abdominal health wheel is a small pusher that can exercise muscles, joints and reduce weight. The material is generally high-quality engineering plastic, with simple design, beautiful appearance, firmness and durability, and easy to use. It is used to exercise the fat of abdomen, waist, hip, arm and other parts of the body. Due to the simple site required for exercise, it is convenient for home use. The abdominal health wheel with power springs can make people easily complete the recovery movement under the retraction elastic force of the power springs when people use it for exercise and when the body is straightened. As we all know, the characteristic of the power springs are made of steel strip. In use, a spring box is required to limit its outer diameter. The center of the spring is connected with the shaft. When an external force is applied to make the shaft rotate relative to the spring, the spring will roll on the shaft center and store the torque. When the external force disappears, the spring will produce the torque on the shaft or spring box. Power springs are often used in products of automatic rewind devices.      The handle rod of the abdominal health wheel is rotationally connected with the wheel body through a bearing, and the handle rods on both sides of the wheel body are provided with power springs. The handle rod passes through the center of the power spring, the inner end of the power spring is connected with the handle rod, and the outer end of the power spring is connected with the side of the wheel body.

The power source of clockwork toy — constant torque spring

Время:2022-9-14

Clockwork toys are not new to children, and children are also very interested in clockwork toys, because clockwork toys will walk around, or go straight or circle, which is very funny. This kind of toy design has lasted for decades. There are many kinds of clockwork toys, mainly cars and animals. They are suitable for children aged 3 to 12. Clockwork toy is the general name of motor toys with clockwork as power device. Spring is a kind of spring machine. In the spring, there is a recyclable coil spring. The principle is similar to that of a gyroscope. When the spring rotates, the coil spring inside is wrapped tightly. In short, it is to accumulate power potential energy, and then the spring returns, which naturally produces power potential energy. The clockwork toy uses a constant torque spring, which is made of stainless steel. The external force reverses the spring from the natural shape to the output wheel (energy storage). When the external force is removed, the spring will return to the natural state and generate constant torque on the output wheel, so it is called constant torque spring. Compared with the power spring, the constant torque spring has the advantage that the torque will not change due to the increase of the number of turns, and there is no limit on the number of turns available. The constant torque spring is mostly used in the design of multiple turns. The number of invalid turns is less, more energy can be stored and the efficiency is higher. When the spring is...

Преимущества беспроводных пружинных компонентов Qianye

All curtain cords, whether installed on the side, caught in curtains, or placed on the back, can be dangerous to children. It is best to replace all corded curtains with cordless curtains in houses where children live or visit, especially in children's bedrooms and play areas. Cordless roller blinds with either a spring system or an electric system can improve the safety of the home.        Cordless roller blinds with spring system are similar to movie curtains. They use the elasticity of the springs. Under the action of the spring components, the roller blinds can be balanced at any position and can be stopped at any time.        At present, most of the spring components on the market are wire spring cordless curtain systems, which have a relatively short service life and a high degree of force attenuation. When pulling down, the curtain stops at each clip, and when rising, pulling down makes the curtain bounce back to the top, which can only make the curtain go up and down within the range, and cannot make the curtain stop freely at any position. The structure is more complex, and it needs to cooperate with damping and limit devices. When the spring force value is attenuated, the feel of the curtain will change.        The core component of Qianye's precision-designed spring cordless curtain system is a spring with a negative gradient. Compared with the traditional wire spring cordless curtain system, the advantages are as follows:        1. Lifespan: Compared with traditional wire spring...

Применение пружины постоянного крутящего момента в 3D-принтере

Время:2022-9-14

3D printing, also known as three-dimensional printing, is a kind of rapid prototyping technology. It uses adhesive materials such as powdered metal or plastic to construct zero objects through multi-layer printing layer by layer. Mold making, industrial design is used to build models, and is now developing into product manufacturing, forming "direct digital manufacturing". Some high-value applications (such as hips or teeth, or aircraft parts) already have printed parts. The constant torque spring is applied to the 3D printer. This innovative case is a spring motor drive system. Like the common design, it is impossible for a spring to achieve the torque we need. As you can see we are using three constant torque springs in one mechanism with an output drum in the middle connecting the three springs. Therefore, it can generate three times the output torque of only one spring, and this design can achieve the purpose of providing maximum torque in a limited space. This connection method is easier to assemble than using screw connections.        When it comes to spring design, design engineers must consider many factors. These factors include not only part function and mechanism design, but also detailed material selection, part connection installation method and size. It's all about manufacturability. Feasibility analysis is required to ensure the functionality meets the customer's needs.        From the initial design stage of the spring set to production and final assembly, Qianye can save customers product development time, find optimized solutions beyond your expectations, no manufacturability constraints in product design, and the best product...

Пружинный двигатель с постоянным крутящим моментом

Время:2022-9-14

A constant torque spring motor is a strip of prestressed spring material that forms a coil and is stored on a small storage drum. The free end is then pinned and rewound onto the larger output drum; this is the "winding" part of the constant torque spring cycle. When the output drum is released, the spring will return to the storage drum to assume its natural curvature, rotating the output drum and providing an almost constant torque.        Constant torque springs are made of type 301 high quality stainless steel and are supplied in coil form for mounting on the motor drum. Its main features are: 1. Long time deflection under almost constant torque. Positive or limited negative gradients can be achieved. 2. Minimal inter-coil friction and resulting hysteresis, which is common in power springs. 3. Rotary motion is provided directly from the output drum or linear displacement by using cables and spools.        Many applications utilize constant torque spring motors, such as: cord retractors, balance retrieval and return applications, drive motors, cordless curtains, and more. The spring features a high turn design, making it ideal for balancing applications. When they are fully turned, the springs apply a constant torque. You can also guarantee high torque levels. This is due to their compactness and high efficiency.        The function of the constant torque spring motor depends on the design. The size of the spring can vary. Therefore, they make them suitable for use in a variety of applications. We strongly recommend that you consult...
