Description of the new type: [Technical field to which the new type belongs] This creation relates to a rotating shaft device that uses MDU springs to provide torque, especially a type of torque device that can be used to provide a specific range of torque, which can make a rotating cantilever must apply a specific range. Only the torque can make it rotate, which can effectively reduce the production cost and production failure rate of the rotating shaft device. [Previous technology] In recent years, the 3C (Computer Computer, Co-Unicatión Communication, Coonsumer—Lu Electronics) consumer electronics industry has developed rapidly. For example, notebook computers, handheld mobile phones, LCD screens, and handheld languages have been developed. Jobs, etc., all need to be used to provide torque, j, rotation, display, n, cover, etc., Lang Ze made some products higher and higher, so that the torque to provide the rotating shaft device is more and more easily damaged, in order to this The use of a rotating shaft device that can provide torque is extended to meet the user's frequent operations. Generally, a suitable rotating shaft device that can provide torque is required to increase its service life. As shown in the first, second, and third figures, it is a conventional rotating shaft device capable of providing torque. The rotating shaft device includes a rotating shaft fixing seat 丄 〇a, two cores, and Ub, several disc springs 12a, a rotating cantilever 13a,-metal reed 14a, a screw 5a and-central axis 16a, the principle is produced by stacking several disk springs The elastic force is used to make the two still pieces hold the rotating cantilever, and the friction between the two abrasive discs and the rotating cantilever is used to provide the required rotational torque. The disadvantage is that the rotating shaft device that provides the torque is known as a disc spring. The elasticity is not enough, so it must be used on the stack of disc springs. Because the lion bomb is disc-shaped, the disc spring stack has ㈣ directionality. Miscellaneous-the direction of the disc spring is wrong, the entire set of torsion shaft devices will At the same time, the disc spring has a small amount of compression but must provide a sufficient amount of spring force. Therefore, when the compression amount is changed slightly, the resulting spring force will become very large, so the range of torque force produced during production is very large, so Each—the axis of rotation The torque which must be adjusted manually when ^, so the failure rate and a high production cost and slow production. 4 M282209 [New content] It is known to provide a rotating shaft device for torsion. The rotating cantilever is clamped by the elastic force generated by the stacking of several disc springs, and the disc spring is secreted in a wear-resistant plate. The friction between the rotating cantilevers provides the rotational torque required to rotate the rotating cantilever. Because the rotating shaft device that provides the torsional force is known, because of the strong spring, the force is not enough, so it must _ number of flexible elastic stacks; and because the disk Rotating springs are recorded lightly, so all the springs are stacked with a fixed directionality. If the direction of the disk is wrong, the entire set of torque will be lost. At the same time, the amount of the disk spring is small but it must provide a high amount. The elastic force is small, so the t compression amount will be changed easily. ► Reliance M will be very large, so the range of the torque produced during production will be very large, so each rotating shaft must be manually adjusted its torque during production, so Its defect rate is high, production speed is slow and production cost is high. This creation provides a rotating shaft device that provides torque. It consists of a rotating shaft holder, a MDU (Microcellular Ductile Urethane polymer) spring, a rotating cantilever, a wear-resistant sheet, a nut and a central shaft. The elastic lens, the rotating cantilever and the _ ^ grinding disc are each provided with a penetration hole for inserting a central shaft, and one side of the central shaft is provided with a screw thread so that the screw cap can be screwed in. After inserting the central shaft into the rotation shaft fixing seat, press the Wear plate, rotating cantilever, wear plate, ► MDU spring, metal cymbal cover on the central axis, and then screw the screw cap to one side of the central axis with the screw teeth to form the entire device. This creation provides a rotating shaft device that provides torsional force. The MDU spring is connected between the wear plate and the metal washer to provide -power to the coffee. The friction force generated by the contact between the wear plate and the rotating cantilever, The friction force is used to form a rotating shaft device capable of providing torque, and only one MDU spring is required. This can improve the assembly problem of using multiple disc springs, and the non-directional nature of the MDU spring can avoid and solve the problem of discs. Due to the directivity problem and defect rate of the shape spring, in order to effectively reduce the production cost; At the same time, the MDU spring has a large shrinkage, so the range of the torque produced during production is small, so each rotation axis does not change during production. The torque must be adjusted manually. M282209 [Embodiment] Please refer to the fourth, fifth, sixth, and seventh drawings.

According to the above aspects, the torsion of the entire group of torques is mixed, and its Gu is to use the spring force generated by a spring to make the two wear-resistant discs clamp the rotation division, and use the two wear-resistant discs to rotate the friction coefficient between the county arms. The generated frictional force provides the required rotational torque. Due to the good elasticity of the elasticity and the amount of consumption required, the number of components is low and the material cost is low.
