The casting seat must be lubricated with the position of the device corresponding to the position of the oil hole of the outer spherical ball bearing.Source:Download:Standard number: GB/T 17809-1999Standard Name: damping material, complex modulus, graphical representationStandard status: currentEnglish Title: Damping, materials--Graphical, presentation, of, the, complex, modulusDate of implementation: 2000-3-1Promulgated by the State Bureau of quality and technical supervisionIntroduction: this standard specifies the graphical representation of complex modulus of viscoelastic damping materials. The method is applicable to simple viscoelastic damping materials with macroscopic, homogeneous, linear and heat flow variability.

It is suitable for the design, manufacture and acceptance of the bearing housings.
The complex modulus can be shear modulus, Young's modulus, bulk modulus, longitudinal wave propagation can also be a lame modulus or modulus. This graphical method is applicable to most viscoelastic damping materials and has sufficient accuracy. This standard also gives the recommended terms, including: parameters, symbols and definitions. The primary objective of this standard is to improve communication between various technical fields involving viscoelastic damping materials.Source:Download:Standard number: GB 7809-1987Standard Name: external sphere, ball bearing seat, dimensionStandard status: voidAlternative: GB 3882.4-1983 GB 3882.5-1983 GB 3882.6-1983 GB 3882.7-1983 GB 3882.8-1983 GB 3882.9-1983; be GB/T 780Date of implementation: 1988-5-1Source:Query keywords
