Application of complex additive in super industrial gear oil;

The wear and friction properties of nanoparticles added to gear oils were compared.

According to the research and investigation for cement production equipments,such as cement rotary kiln and all kinds of deceleration machines,which being widely used in domestic large and medium cement manufactories,KG series heavy-duty industrial gear oil,KG/S synthetic gear oil,open gear oil,DW oil and No.

The three-dimensional dynamic simulation of gear oil pump based on virtual design;

The struture feature of the circle arc cycloidal gear oil pump is described.

Based on the theory analysis,the reason was discovered of oil- blocking during the operation of a gear oil pump,which resulted in power loss,vibration and noise.

Taking gear pump as an example,the text introduces the method to construct virtual reality model of the mechanical product and realizes the key technology virtual assemblly and disassembly of the mechanical product.

The total scheme about the parametric system for gear pump and the parametric model of products were pointed out after the crucial technology in the parametric designing was theoretically analyzed,and then,the relationship between the driving dimension of assemblies and parametric system was analyzed,too.
