GB/T 10821-2008V-belt and V-ribbed belt for agricultural machines -- Dimensions (English PDF)

Foreword

This standard corresponds to ISO 5289:1992 "Agricultural Machinery endless hexagonal belt and pulley wheel groove corresponding cross-section" and ISO 3410. 1989 "Agricultural machinery and the corresponding endless transmission V belt pulley wheel groove cross-section" of this standard and ISO 5289:1992 and ISO 3410. 1989 is consistent the degree of non-equivalent.

This standard replaces GB/T 10821-1993 "agricultural machinery V-belt size." this standard and GB/T 10821-1993 compared to the main changes are as follows.

--- Increased introduction and reference standards (see the Preface and reference standards);

--- Increasing the scope of agricultural machinery with a narrow V-belts and agricultural machinery ribbed belt size Size (1993 Edition Chapter 1 edition Chapter 1);

--- Omitted agricultural machinery V-belt cross-sectional size, the length of the reference series, pulley measuring parameters and measurement conditions, a direct reference to GB/T 11544 and HG/T 3745, (1993 edition of 5.1,5.2,5.3,5.4,6);

--- Increasing the agricultural machinery with a narrow V belt size requirements (see Chapter 5);

--- Increased agricultural machinery ribbed belt size requirements (see Chapter 7);

--- According to the American Society of Agricultural Engineers Standard ASAES211.5JUL98 "agricultural machinery and ribbed V-belt drive," agriculture Machinery and ribbed V belt size parameter to increase effective system of Appendix A (see Appendix A).

Appendix A of this standard is an informative annex.

1 Scope

This standard specifies the use of agricultural machinery V-belt, narrow V-belt, V-belt transmission (hereinafter referred to as "V-belt"), hexagonal and ribbed belt (hereinafter Referred to as "belt") main dimensions and methods of measurement.

This standard applies to agricultural machinery in general drive ordinary V belt and narrow V-belt, double-sided hexagonal drive belts, V-belts and multi-variable transmission Wedge belt drive V-ribbed belt.

If according to the American Society of Agricultural Engineers Standard ASAES211.5JUL98 manufacture of agricultural machinery and ribbed V belt, its size refer to Appendix A for production.

3 Common Agricultural machinery Vp Size

Sectional size, V-belt can be divided into HA, HB, HC, HD and other models, the group V-belt in front of the model plus the number of joint group (with a number of Arab Word indicates), dimensional accuracy V-belt is checked by measuring the V belt measuring machine wheel groove. Its cross-sectional size is equivalent to GB/T 11544 the A, B, C, D four models and HG/T in 3745 AJ, BJ, CJ, DJ four models.

4 Agricultural machinery Hexagon Size

Cross-section 4.1

Theory is a hexagonal cross section with. The hexagon is composed of two identical, overlap each other in a large isosceles trapezoid bottom thereof. because this neutral zone face (actually hexagonal lateral diagonal coincides) with the total height should be located at half. According to cross-sectional dimension, with it can be divided into HAA, HBB, HCC, HDD models. Sectional dimensions of the various models of the belt shown in Table 1, Figure 1.
