摘要:
Planetary gearing, in particular multistage planetary gearing, is disclosed. The planetary gearing includes at least one drive shaft, an output shaft, a sun wheel, a ring gear, planet wheels assigned to the planetary gear train, a gear casing, in particular a multipart gear casing, a planetary gear train, in particular the second planetary gear train, comprising a planet wheel arm immovably arranged in a casing. The construction of such a planetary gearing is simplified compared to the prior art, thereby saving costs. This is achieved in that the planet wheel arm is integrally formed with a casing.
摘要:
A planetary gear set with a planet stage revolving in a gear set housing has a planet carrier which is connected in particular to a rotor and has planet web cheeks which are connected to one another by means of webs, and a plurality of planet gears which are mounted in planet gear bearings, which are connected to the planet carrier, and are in engagement on one side with a sun gear and on the other side with a ring gear. The gear set housing is provided with an oil supply channel which is connected to at least one oil-guiding channel in the planet carrier. The lubrication of the meshing engagements is facilitated in the planetary gear set by providing dry sump lubrication. This is achieved in that at least one channel connected to the oil-guiding channel is embedded in each web, said channel being aligned with the meshing engagements between sun gear and planet gear and/or planet gear and ring gear.
摘要:
A process is described for reducing the residual monomer content in a liquid solution, mixture, melt, suspension or dispersion of a polymer by postpolymerization with addition of a redox initiator system at a reaction temperature appropriate to it and with an extremely short mixing time of the liquid system in the production reactor by metering—gradually, in portions or continuously—at least one of the redox initiator components required to initiate polymerization of the residual monomers over a period (metering time) which is from about 10 to 250 times the mixing time of the liquid system in said reactor.
摘要:
A reactor for chemical reactions, especially polymerization reactions, and in particular a reactor for emulsion, suspension, solution, bulk and/or precipitation polymerizations, which has a stirring mechanism, incoming and outgoing lines and a removable lid, and where both the stirring mechanism and incoming and outgoing lines are installed on the reactor floor. The novel reactor is quick and easy to open and clean and permits simple and rapid changeover of the installed stirring elements.
