Through multi-objective optimization design and simulation analysis of a single stage helical gear reducer, the following conclusions can be drawn. 1) Based on theoretical calculations, the difference in maximum bending stress between the wheel and pinion gear roots of the optimized front reducer is 21.3577 MPa, while the difference...
The factors that cause transmission errors in the spur gear system include manufacturing errors of the spur gear itself, tooth modification, load deformation, deformation of the spur gear shaft, system installation errors, bearing motion errors, etc. 1. Accumulated error of tooth pitch Fp Fp is mainly caused by factors...
Transmission error is a key performance indicator for evaluating the transmission accuracy of planetary gear transmission systems, and it is also a source of excitation for vibration and noise in planetary gear systems. At present, research on transmission error is mostly limited to the analysis and testing of a...
Transmission error refers to the deviation between the actual output angle and the ideal angle of a helical gear along the direction of the meshing cooperation line. It is the main indicator of the vibration instability of helical gears and has a significant impact on the dynamic performance of...
A kind of traction underactuated pull in manipulator based on planetary gear mechanism is designed. The fingers of the manipulator are distributed circumferentially, which is suitable for grasping rigid and flexible objects. The most obvious advantages of the manipulator are as follows: (1) By using the planetary gear mechanism,...
In general, the underactuated manipulator driven by motor usually uses the dynamic coupling effect to realize the underactuated form of the manipulator, while the planetary gear reducer is used to distribute two driving torques to achieve the underactuated form of the manipulator. Its transmission structure is shown in Figure...
The manipulator is the part that directly contacts with the target object and plays the role of clamping and pulling in the target object. The structure of a single finger is shown in Figure. The worm 1 and the worm gear 1 control the rotation of the joint 1....
