Abstract: A transmission mechanism includes a planet carrier, a planet gear, a pin, a sliding bearing, and thrust bearings. The planet gear is rotatably disposed on the planet carrier through the pin. The thrust bearings are disposed between one end of the planet gear and the planet carrier, and between another end of the planet gear and the planet carrier, respectively. A first lubrication gap is formed between each thrust bearing and an end surface the planet gear. The sliding bearing is sleeved on the pin and is disposed between the planet gear and the pin. A second lubrication gap is formed between an inner circumference of the sliding bearing and the pin or between an outer circumference of the sliding bearing and the planet gear. Oil channels are disposed on the pin. Lubricating oil enters the first lubrication gap and the second lubrication gap through the oil channels respectively.

Abstract: Provided is an assembly structure of sun gear shaft and spline shaft of a gearbox for wind turbine. The assembly structure relates to the technical field of gearboxes for wind turbine and includes a sun gear shaft, a spline shaft, a mechanical pump drive gear, and a distance ring. The spline shaft is a hollow shaft. One end of the sun gear shaft is inserted into the spline shaft. The one end of the sun gear shaft inserted into the spline shaft is connected to the spline shaft through a spline pair. The mechanical pump drive gear is mounted at one end of the spline shaft. The inner diameter of the mechanical pump drive gear is less than the inner diameter of the spline shaft. The distance ring is disposed in the spline shaft. One end of the distance ring abuts against the inner side of the mechanical pump drive gear and is securely connected to the mechanical pump drive gear. Another end of the distance ring is spaced from the one end of the sun gear shaft in the spline shaft.

Abstract: The present disclosure relates to the provision of novel biodegradable amphiphilic peptides and peptide analogues based derivatives comprising hydrophobic chains and their use in the permeabilization of mammalian cells and delivery of agents, for example therapeutic agents, imaging agents and cell preservation agents.

Abstract: Processes of preparing defined monomer sequence polymers are disclosed, in which a backbone portion of the polymer is first prepared by performing one or more sequential monomeric coupling reactions with intervening membrane diafiltration purification/isolation steps, followed by a step of decorating the backbone portion with one or more side chains at predetermined positions along its length. The process represents an improvement on prior art techniques, which impose limitations on the size of the side chains that may be present. Defined monomer sequence polymers that are obtainable by the processes are also disclosed.
