An analysis model about the deposition characteristics of oil droplet on the housing in a bearing chamber is proposed to provide the basic conditions of oil film flow investigation. Firstly，the transition criteria for droplet/ housing interaction is determined，and considering the temperature variation of droplet，the deposition mass and momentum of oil droplet on housing are obtained for different impact phenomena. Secondly，the deposition heat energy is calculated based on the law of conservation of energy and the cooling effectiveness of oil droplet impacting on chamber housing. Lastly，the effects of droplet temperature，shaft rotational speed，droplet diameter and air inlet temperature on the deposition characteristics are discussed. The calculated results show that，after considering the temperature variation of droplet，the rates of deposition mass and momentum are all decreased; The rates of deposition mass，momentum and heat are all decreased with the increasing of shaft rotational speed and droplet diameter，and the rate of deposition heat is increased with the increasing of air inlet temperature.
