Planetary gear test bench for simulating multi-working-condition environment and working method

Abstract

The invention discloses a planetary gear bench for simulating a multi-working-condition environment. The planetary gear bench is characterized by comprising a power unit, a load unit, a test box unit,a salt spray unit, a temperature control unit, an oil liquid unit and a control and display unit; the planetary gear is arranged in the closed test box unit, after the planetary gear mechanism is driven by the power unit, the output of the planetary gear mechanism is combined with the load unit to generate a load, and the salt spray unit, the temperature control unit and the oil liquid unit are opened or closed by the control and display unit according to different simulation states. The bench can meet the test requirements under dry friction service conditions at different temperatures, lubricating oil service conditions at different temperatures and salt spray service conditions, and meanwhile, the damage evolution process of the planetary gear mechanism under different working conditions can be obtained by monitoring the motion state of the rack in real time.

Description

Technical field: [0001] The invention relates to the technical field of a planetary gear mechanism, in particular to a planetary gear mechanism test bench for simulating multiple working conditions and its working method. Background technique: [0002] Planetary gear transmission is one of the most commonly used transmission schemes for transmitting power and changing the transmission ratio. It is widely used in wind power, ships, and automobile industries because of its collinear input and output shafts, large load-carrying capacity, and large transmission ratio. Reducer, speed change device and other devices. [0003] And because planetary gears are mostly in harsh working conditions such as variable load (wind power gearbox), high and low temperature, salt spray (ship gear), etc., due to long-term operation, wear, pitting, and gluing between teeth are prone to occur , cracks and other damage behavior. [0004] The above-mentioned damage behaviors not only affect the tra...
