STUDY ON PROFILE MODIFICATION OF GEAR COUPLING USED IN PLANETARY TRANSMISSION
Jixie qiangdu, 2016 For the planet transmission device whose sun gear shaft is connected with tooth coupling,floating displacement of the sun gear directly determines tilt angle compensating of the tooth coupling,However,because of the sun gear ’s floating displacement ...

On the Meshing Efficiency of 2K-2H Type Planetary Gear Reducer
Advances in Mechanical Engineering, 2013 This paper proposes 2K–2H type planetary gear reducer and analyzes its meshing efficiency. First, according to the concept of train value equation, the kinematic design of 2K–2H type planetary gear reducers is carried out. Three 2K–2H type planetary gear

AGRICULTURE IN A SOCIALIST CITY: Towards an Alter‐Urban Political Ecology
International Journal of Urban and Regional Research, EarlyView.Abstract Urban political ecology has developed as a critique of capitalist urbanization. This article develops the concept of alter‐urban political ecology to define urban environments emerging not from capitalist urbanization but from efforts to transform it. Drawing on archival research and ethnographic fieldwork in five urban farms in socialist Cuba,

Mitigating the human link in emerging reptile fungal pathogen transmission
Conservation Biology, EarlyView.Abstract Handling wild reptiles is common among amateur herpetology enthusiasts, professional researchers, social media influencers, and photographers. However, the potential for these interactions to spread diseases that threaten wild reptiles remains underappreciated.

Assessing the effectiveness of Sri Lankan marine protected areas: Challenges and recommendations
Conservation Science and Practice, EarlyView.We evaluated the biodiversity conservation effectiveness of 32 zones of Sri Lankan marine protected areas (MPA) and found that most are currently insufficiently protected. Threats to MPAs were not uniform, with harmful dredging/dumping, anchoring, fishing, and non‐extractive activities identified as major pressures affecting different sets of MPAs.

Unified Assembly Condition of Evenly and Non-evenly Spaced Planet Gear
Jixie chuandong, 2020 A unified assembly condition formula is derived for planet gears，taking the NW planetary gear train as an example. Firstly，the minimum non-zero misalignment angle between the two teeth of compound planetary gears is determined.

Journal of Fish Biology, EarlyView.Abstract Although Macrourus species are the main by‐catch across Southern Ocean longline fisheries, including around South Georgia, the lack of species‐specific data has hindered effective management and ecological understanding. Aggregation of macrourids at genus level masks critical interspecific differences in life‐history strategies and ...

Analysis of the Dynamic Load Sharing Characteristic of Two-stage Planetary Transmission
Jixie chuandong, 2016 To study the dynamic load sharing characteristics of two- stage planetary gear train,a translation- torsion coupling dynamics model is established by taking the nonlinear factors like time- varying mesh stiffness,position error,eccentric error,gear ...
