Research on the Temperature Characteristics of Movable Tooth Trans- mission Motor of Electromagnetic Harmonic

Based on the heat transfer characteristics of electromagnetic harmonic movable tooth transmission motor, this paper adopted the finite element method to establish a three-dimensional temperature field model for numerical calculation on the basis of four basic assumptions. It analyzed the heat loss and gave out the functional to calculate the temperature field within each medium and obtain the temperature distributing curves. Then taking the prototype as an example, it calculated the steady-state temperature field of the system under different loading. The comparison between the results and measured values has verified the reasonableness of the established model and calculation method employed. The results could provide a theoretical basis for the optimized design of electromagnetic harmonic tooth transmission system.
