Purpose
The purpose of this paper is to examine the effect of application of a heat pipe in an aspect of hydrostatic thrust bearings on thermal balance and deformation and the role of this application in increasing the rotating speed of a workbench.
Design/methodology/approach
Numerical simulations of oil film temperature field, the temperature field and thermal deformation of the bearing’s workbench and base were performed by finite element analysis (FEA) software for both the traditional hydrostatic thrust bearings and the heat pipe ones.
Findings
Oil pad and workbench of the hydrostatic thrust bearings are fabricated with a heat pipe cooling structure, which can take away most of the heat generated by shearing of the oil film, control the temperature rise and thermal deformation of the hydrostatic thrust bearing effectively, avoid the dry friction phenomenon and finally improve the processing quality of equipment.
Originality/value
The heat pipe hydrostatic thrust bearings could control the temperature rise and thermal deformation of the hydrostatic thrust bearing effectively, avoid the dry friction phenomenon and improve the processing quality of equipment.
The gear teeth have influence on the stresses in flexspline, through the influence coefficients of gear tooth of flexspline. For the purpose of theoretically clarifying this influence, the profile of the gear tooth of the flexspline is simplified as two simple shapes of rectangle and trapezoid. The gear tooth influence on the stresses in the flexspline has been studied and analyzed on this two cases, and the two simplified tooth profiles of rectangle and trapezoid have been compared with each other.
The flexible bearing break is an important factor to influence the life of harmonic drive, this paper first introduces the research situation of fatigue fracture above this the design of flexible bearing fatigue life test device of the no-load and load conditions. The device includes a driving part, a loading device, the break device and the monitoring device of bearing`s revolution when it break.
In this paper, the development process of BOPF technology was described, the tubular film stretching method and planar biaxial stretching method were compared, several types of one-step biaxial stretching equipment were introduced, and the prospect of the development of biaxial stretching was given.
Fashion, known as the flow of soft sculpture, is the perfect combination of technology and art. Using the three key elements of styles, colors and materials, the three-dimensional shape of garment is formed eventually. The development of computer science, especially applying the 3D scanning technology to fashion design, has made intelligent modeling realized which is impossible of using traditional design methods. In this paper, our research would extend the design thinking and method through the approach of style modeling based on the new 3D technology, form a more reasonable garment structure, and guide the innovation of clothing production mode. With the improvement of the media and computer technology, there will be more innovative forms applied to the design and development of garment.
