 Small engines are well known and are commonly used in lawn mowers and garden tractors and various other garden and lawn maintenance tools, in addition to other environments. Typically, each of these engines is equipped with a recoil starting system that includes a rope that rotates the starting mechanism to engage a flywheel that is connected to the engine for starting purposes. Once the rope starter is pulled, the recoil mechanism is always provided with the engine to reel the starter rope back to the starting mechanism.   The recoil portion of the starter mechanism is operated by a power spring that tensions when the operator pulls on the starter rope. Once the rope is fully pulled, the operator releases it. Most power springs on the market often fail, so the recoil rewinding mechanism needs to be disassembled and the spring replaced. And replacing the spring is a tedious task because the operator needs to keep the spring in the cavity inside the recoil starter pulley and then coil the spring into the pulley mechanism while keeping the spring in the coiled position and under sufficient tension. Such a procedure requires not only skill, but sometimes infinite patience. That's why the quality of the power spring is a top priority - after all, no one wants to change the power spring inside too often.   Shenzhen Qianye Precision Metal Co., Ltd. was established in 2006 to supply high-quality stainless steel springs for many fields. Through continuous efforts, 20 patent certificates and 4 spring equipment software copyrights have been granted by the State Intellectual Property Office, and an enviable...

Constant torque spring is a constant force spring with special force moving between two spools. The spring is stored on the storage spool and wound reversely on the output spool. When released, torque is obtained from the output spool when the spring returns to its natural curvature on the storage spool. The spring does not need to be connected to the storage spool. The spring can be installed in a cavity without storing the spool at all. However, friction will then be introduced and torque requirements will change. The torque generated by the constant torque spring will increase slightly after several revolutions. Constant torque, even negative torque, is also possible. Negative gradients of up to 50% can be achieved in some applications. As for the design of constant torque spring, when considering the use of constant torque spring, it is strongly recommended that you talk with Qianye engineers and study various design parameters. Some initial design calculations can be carried out according to the following eight steps. 1. Select materials Most of the springs we produce are made of type 301 stainless steel. This material is readily available and predictable. Thousands of industry engineers can assist in selecting standard sizes to speed up the process. We also use high carbon steel, Inconel and Elgiloy in various designs as needed. 2. Life expectancy This is one of the most important considerations because the life of constant torque springs is very predictable. Practical is important because it is estimated that high life cycle requirements may lead to larger and more expensive designs. Of...

Springs are integral components in the manufacture of many medical devices. Whether it’s for a surgical stapler or a medical monitor, the types of springs in medical devices are defined by a specific action or movement required for the application. Though relatively simple in its design, springs store the mechanical energy necessary for a wide range of medical devices, machinery, and equipment to function properly. Any type of surgical instrument, medical equipment or device that has a mechanism undoubtedly has a spring component. Spring material must be medical grade, and the design and function of any device must adhere to stringent regulatory requirements and guidelines as defined by the FDA. Booms, table and bed lifts, fluid control devices, wheelchairs, medical testing and monitoring equipment either fixed or mobile, MRI and X-ray machinery, dental x-ray with articulated arms, medical equipment drawer closing mechanisms, anesthetic infusion devices, sterilization valves, various implants, and shunt valves are all examples of medical devices that require springs to function. Manufacturers of medical devices and devices subsequently relied heavily on springs in a variety of applications. The medical industry relies on the same types of springs that most industries rely on—constant force springs, constant torsion springs, power springs. Constant force spring Constant force springs are coiled with stainless steel tape so that when coiled relative to being stretched, the spring relaxes in a low stress state. When it is unrolled, the restoring force comes mainly from the portion close to the unwinding spring coil. The resultant force is almost constant. The actuators that operate in the surgical...

 A support device for assisting a patient is used to assist the movement of a patient at the patient support device. In the prior art, a caregiver would operate a patient lift or motor by guiding the lift to raise or lower the patient at the patient support. Such manipulations often require the precise manipulation of heavy forceps and motors by a paramedic to help the patient move around the patient support.        The support means may incorporate a constant force spring design, the support structure comprising a base and an upper portion extending upwardly from the base. The constant force spring assembly may include a carrier slidably coupled to the base secured to a first end of the carrier. The base may include channels that guide sliding movement of the carrier relative to the base of the support structure. The constant force spring assembly may also include a spool and a motor configured to drive the spool. The auxiliary belt may be secured to the spool so that the auxiliary belt is wound and unwound from the spool in response to a motor driving the spool. And the motor can be fixed to the carrier to move with the carrier.        Constant force springs get their name because their motion force is constantly applied. The load is determined by the width and thickness of the material and the diameter of the coil. The tightly wound rollers work in a linear motion, not obeying Hooke's law (F=kX), but constantly generating forces as they deflect.These springs provide...

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.

Constant force spring, also known as hair spring, is made of stainless steel strip. The force added to the spring determines the diameter, force and life of the spring. The action of constant force spring is similar to that of stretching ribbon. The spring stretches and rolls back, and the working part is tangent to the spring ' s own circle. As long as the diameter of the spring is certain, the force of the spring is constant. According to the application principle of constant force spring, constant force spring can be divided into linear constant force spring and rotational constant torque spring. When linear stretching force units are : kg, Newton, pounds, etc.     Then how long can the constant force bar be used ? The life of the constant force bar is limited, and the life requirement of the spring should be considered when designing the constant force bar. This step is important because it affects the things behind the design ; improper consideration may lead the design to a wrong direction ; properly considered, the design will be easier to succeed. It is very important to determine the number of spring stretching before designing the constant force bar. Spring stretching times explanation : a refers to the spring in any part of a stretch and roll back process. Since the constant force spring provides force through the bending of the spring, any part used belongs to the spring body. In other words, a spring with a total design length of 25 ’ uses the length of...

How to choose double torsion springs suppliers, what is double torsion springs

Time:2022-11-21

A torsion spring is a coil spring that stores and releases angular energy or holds a mechanism in place. They feature two legs extending from each end of the coil and are used in applications requiring torque or rotational force. This is accomplished by attaching the legs to external components. Then, as the elements rotate around the spring, the spring tries to push them back to their original position. Torsion springs come in a variety of different shapes and sizes, with different leg configurations and lengths, for a wide range of applications. Typical uses include automotive door handles, garage doors, clothespins, bulldog clips and hinges. In some cases, a single torsion spring cannot exert enough force. In these cases, a double torsion spring may be required.     What is a double torsion spring? As the name implies, a double torsion spring is characterized by two torsion spring coils joined at the center to form one spring. The two coils are made of a wire wound in opposite directions, one counterclockwise and the other clockwise. The two parts work in parallel, like a torsion spring, with the spring legs normally pressing against the outer assembly, which pushes the outer assembly back, creating resistance. The shaft or rod usually passes through the center of the two coil bodies.   Dual torsion springs are stronger than single torsion springs and can apply more force. The resulting force is equal to that of two separate springs combined. Depending on the application, the bridge and legs connecting the two coils can be made in...
