Product description
The worm gear and worm professionally produced by Demai transmission provides stable motion and high torque in the humanoid robot, realizing multi angle transmission, accurate grasp and release, stable support, stable rotation at the waist and neck, increasing motion accuracy, assisting the transmission of special parts, and meeting the requirements of miniaturization and lightweight.
Structure and working principle
Worm gear is composed of worm and gear. Worm is similar to screw with V-shaped thread, and gear is similar to spur gear. The worm is usually the driving part. The thread of the worm advances the teeth of the gear. Worm gear is an important motion control component, which can reduce the speed or increase the torque output.
Worm gear features
(1) Large transmission ratio and compact structure; (2) The meshing tooth surfaces of the two wheels are in line contact, and the bearing capacity is greater than that of the staggered helical gear mechanism; (3) Stable transmission and low noise; (4) It has self-locking property. When the lead angle of the worm is less than the equivalent friction angle between the meshing teeth, the mechanism has self-locking property and can realize reverse self-locking, that is, the worm wheel can only be driven by the worm, but not by the worm wheel, which has the function of safety protection.
Provides stable movement and high torque
DeMar transmission is specialized in the production of humanoid robot joints such as arms and legs, which need to accurately control the movement and bear a large load. Because the worm gear has high transmission ratio and self-locking function, it can convert the high-speed and low torque output of the motor into the low-speed and high torque movement required by the joint, ensure the stability and accuracy of the joint in the process of movement, and prevent the unexpected reverse movement of the joint at rest, so as to maintain the stability of the robot posture.
Realize multi angle transmission
It can change the direction of power transmission, realize the rotation movement in different directions, meet the motion requirements of joints in different attitudes, and make the joints of humanoid robot rotate more flexibly to complete various complex actions.
