GB/T 5837-2008Fluid coupling - Types and basic specifications (English PDF)

Foreword

This standard is GB/T 5837-1993 "hydraulic coupling types and basic parameters" amendments.

This standard compared with GB/T 5837-1993, the main changes are as follows.

--- The Chapter 2, "type" with "types and categories."

--- Original 2.1 "basic version" to "type" and are listed in the "basic version" and "derived types" in 2.1.1,2.1.2 in "Derived type" increase "can be synchronized hydraulic coupling", "torque converter coupling."

--- Original 2.2 "Derived Type" to "category" and in 2.2.1,2.2.2,2.2.3,2.2.4,2.2.5 They are listed in the "Normal Hydraulic coupling category "," constant filling fluid couplings category "," the governor hydraulic coupling category "," fluid coupling transmission unit Set category "" hydraulic retarder (hydraulic brake) category "under each category divided into several subcategories according to different classifications, from And more fully reflect the product information; "synchronize hydraulic coupling", "torque converter coupling" at the time of the revision temporarily stars category.

--- 2.3 in the original model diagram showing the "structural features of the code" is replaced by "category code" can be a number, and with sinking characters. In the "cycle The effective diameter of the circle, "add the symbol"/"and increase the" work round the permissible maximum speed (r/min) "and" Using media code "to cancel The original "update code."

--- Original 2.3 Table 1 (type code and structural features of the code) is divided into "hydraulic coupling types and code, common hydraulic coupling Category and code, constant filling fluid coupling and category code, the governor hydraulic coupling and category code, fluid coupling drive Device category and code, category and hydraulic retarder code-named "a total of six tables, each hydraulic element category code by a certain letter System layout, to avoid duplication; Table column order represents the actual writing time, some of the categories, code-named selectively represented, see table notes Instructions.

--- Detailed markup example constant filling fluid coupling, hydraulic coupling devices and fluid coupling transmission device in 2.4.

--- Original 3.1 "Table 2" is replaced by "Table 7", by deleting the table "125,140,160,1800,2060" five almost no specifications; and Add "600,1250" two specifications.

--- Original Table 3 to Table 9, Table 4 to Table 8 primary and general hydraulic coupling limit filling hydraulic coupling are shown in the same table In; the pump wheel torque coefficient table "lambda beta" to "pump wheel torque coefficient lambda B". The original table 4 (now Table 8) pump wheel torque coefficient column 1.3 x 10^-6 to 1.45 x 10^-6,1.45 x 10^-6 to 1.55 x 10^-6,1.55 x 10^-6 to 1.65 x 10^-6 and Speed hydraulic coupling and hydraulic coupling gear column 1.65 x 10^-6 to 1.8 x 10^-6; and Table 8 charge Code rate was changed by the q v q c.

--- The Appendix A "(informative)" to "(informative)", and placed under "Appendix A", and "pump wheel torque" to "pump wheel Torque. "

Appendix A of this standard is an informative annex.

The standard proposed by China Machinery Industry Federation.
