According to Hertz contact theory, this paper derived the checking formula for contact strength of the circular-arc-tooth-trace cylindrical gear (C-gear) train. The contact strength calculation formula is particularly considering the effect of radius of tooth trace and position angle. The contrast analysis of contact strength between the C-gear, spur gear and helical gear was investigated by computer...
In order to meet the stereo vision navigation of the autonomous robot, stereo vision initial pose estimation based on unit quaternion is put forward and pose estimation accuracy is predicted and analysed. The research provides basis for further improving the pose estimation accuracy of robot. Gauss-distributed error covariance matrix propagation model was adopted to deduce the error propagation formulas...
The anti-backlash double-roller-enveloping hourglass worm gearing is multi-tooth meshing transmission and it has complex tooth profile. It is difficult to obtain the load distribution among the meshing tooth pairs and the stress distribution along contact line with analytical model. So, based on the geometrical model of the anti-backlash double-roller-enveloping hourglass worm gearing, the Finite...
Based on the DSP controlling of TI company kind of design of wheeled mobile robot platform design, the purpose is to make the control system of soccer robber more stable and efficient The design makes full use of the resources of TMS320F2812 event manager constitutes electric machine control module, ultrasonic ranging module, infrared communication module and temperature compensation module. Adopting...
Aimed at numerous joint freedom of humanoid robot and the complex control situation of motor, this paper presents a hierarchical control structure and a modular design project for bottom joint controller. To combine the capability of high-speed data processing of DSP and the predominant control performance of 8-bit MCU, the design chooses TMS320F2812 for coordination layer and P89LPC9201 for execution...
In this paper, a new kind of the anti-backlash double-roller enveloping hourglass worm (ADEHW) with line contact between intersecting axes has been studied by means of the theory of gearing and the space engagement theory for the first time. The engagement equation and tooth profile equation have been derived by applying the theory of gearing. Meanwhile the important factors that impact the performances...
