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...

The speed difference anti-fall device can quickly brake and lock falling objects within a limited distance, which is suitable for cargo hoisting and protects the life safety of ground operators and the damage of the lifted workpiece. It is suitable for safety protection to prevent the workpiece from being lifted accidentally when the crane is hoisted. It can effectively protect the life safety of ground operators and the damage of the workpiece to be lifted. It is used in metallurgical automobile manufacturing, petrochemical industry, engineering construction, electricity, ships , communications, pharmaceuticals, bridges and other high-altitude workplaces.   So do you know how the speed difference crash arrester works?   When there is no solid structure above the operating point for fixing the safety rope, the working platform cannot be set up temporarily, and it is inconvenient to use the safety belt at the same time, the differential fall arrester can be used, which is also a supplement and improvement to the protection of high-altitude operations. . The speed difference anti-fall device is mainly composed of a suspension system and an anti-fall braking system. The suspension system is composed of hooks, nylon ropes and telescopic safety ropes. The anti-fall braking system is mainly composed of a shell, a ratchet, a power spring and a pawl.   The speed difference fall arrester uses the falling speed difference of the object to quickly brake and lock the falling object within the set distance. It is required to hang high and use low.   When in use, it only needs to tie the lifting rope to...

3Dプリンターにおける定トルクバネの応用

時間: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...

How long can stainless steel springs last? This is a common problem. You might think that as long as it's not stretched beyond the point of recovery, the spring will always return to its original shape. A spring is a mechanical part that uses elasticity to work. Parts made of elastic materials deform under the action of external force, and return to their original shape after the external force is removed. Also known as "spring". Generally made of spring steel, the types of springs are complex and diverse. However, spring life depends on many factors.         1. Spring design Are they properly designed for their intended purpose? Many are not, errors in spring design are the main cause of premature spring failure. When choosing a spring, remember to pay attention to what it is for and how it will be used. Is spring strength more important or elasticity? If you're not sure, experts can help guide your decision.       2. Quality of manufacturing materials       The life of the spring is also related to the quality and modulus of elasticity of the materials used in its manufacture. Make sure your springs are made of the best quality material for the desired application. For example, stainless steel springs have high strength, low stress relaxation, corrosion resistance and heat resistance. However, their performance decreases at sub-zero temperatures.       3. Application pressure and environmental conditions       If the force applied is greater than the spring is designed to withstand, fracture may occur....

Removal or extraction of the lead may be difficult. As mentioned above, the body's natural healing process forms scar tissue over and along the lead, and possibly at its tip, thereby encasing at least a portion of the lead and fastening it even more securely in the patient's body. In addition, the lead and/or tissue may become attached to the vasculature wall. Both results may, therefore, increase the difficulty of removing the leads from the patient's vasculature. A device for removing an implanted object from a body vessel, may comprise a sheath assembly comprising an outer sheath assembly and an inner sheath assembly, and a pin, the outer sheath assembly comprising an outer sheath and an outer band, the outer band coupled to the pin, the inner sheath assembly comprising an inner sheath and a tip, wherein the tip has a cutting surface, the inner sheath comprising a proximal end and a distal end, wherein the distal end of the inner sheath is coupled to the tip, the tip comprising a cam slot for receipt of and cooperation with the pin, and a handle assembly comprising a trigger and a barrel cam cylinder, the trigger comprising a trigger pin, the barrel cam cylinder comprising a barrel cam cylinder slot for receipt and cooperation with the trigger pin, wherein the proximal end of the inner sheath is coupled to the barrel cam cylinder such that upon the trigger pin moving proximally in a longitudinal direction, the barrel cam cylinder rotates in both a clockwise direction and a counter clockwise direction, thereby...
