GB/T 15096-2008Hydroviscous variable speed clutch (English PDF)

Foreword

This standard replaces GB/T 15096-1994 "Liquid Viscosity Speed \u200b\u200bRegulation Clutch." This standard and GB/T 15096-1994 compared to the main changes are as follows:

--- Delete the contents on the outside diameter of the friction plate prescribed value;

--- Adds the content type of the product closed loop electronic control. The standard proposed by China Shipbuilding Industry Corporation. This standard by the National Standardization Technical Committee diesel marine machinery Technical Committee. This standard is drafted by: China Shipbuilding Industry Corporation seventh eleven Institute. Participated in the drafting of this standard. Hangzhou Advance Gearbox Group Co., Ltd., Beijing Materials Handling Research Institute, Beijing Institute of Technology. Drafters of this standard. Wu Fan, Wang Tian Chi, Ji Wen, Liu Peng, Xuan Anguang, Zoutie Han, Yan Qing East Dexiang. This standard superseded standard previously issued as follows:

--- GB/T 15096-1994. Liquid Viscosity Speed \u200b\u200bRegulation Clutch

1 Scope

GB/T 15096-2008 is the Chinese national standard on hydroviscous variable speed clutch, in the field of mechanical systems and components. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 19 June 2008 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 15 December 2008. Classification: ICS 21.120.20, CCS J19. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This standard specifies the viscous fluid clutch speed classification, requirements, test methods and inspection rules. This standard applies to viscous Speed \u200b\u200bgoverning Clutch (hereinafter referred to as a clutch) design, manufacturing and testing.

3 Terms and Definitions

The following terms and definitions apply to this standard.

3.1 Liquid as the working medium, relying viscous liquid to pass power transmission mode.

3.2 According to fluid viscosity transmission mode, by changing the master, the oil film thickness between the driven friction plates and adjust the output speed of the transmission function of both the clutch Means.

3.3 The main, driven friction plates holding the liquid viscous transmission desired axial force, this force is usually pressurized by the piston through the pressure plate is applied to the friction plates.

3.4 In a sufficiently large pressing force, the driving and driven friction plates engagement, input and output speed of the same working conditions.

3.5 When the pressing force is small enough (control pressure is close to zero), the driving and driven friction plates fully disengaged working conditions.

3.6 When changing the pressing force between the primary and driven friction disc clearance changes, so that the output speed is below stable condition input speed.
