Synchronous belt drives--Trapezoidal toothed pulleys with pitch code MXL, XXL, XL, L, H, XH and XXH ICS 21.220.10 J18 National Standards of People's Republic of China Replace GB/T 11361-2008 Timing belt drive pitch models MXL, XXL, XL, L, H, XH and XXH trapezoidal toothed pulleys MXL, XXL, XL, L, H, XHandXXH (ISO 5294.2012, Synchronousbeltdrives-Puleys, MOD) Published on.2018-12-28 2019-11-01 implementation State market supervision and administration China National Standardization Administration issued ForewordThis standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces GB/T 11361-2008 "Synchronous belt drive trapezoidal toothed pulley". Compared with GB/T 11361-2008, except editing The main technical differences outside the sexual modification are as follows. --- Added pulley model and marking (see Chapter 3); --- Modified the limit deviation of the tool pitch (see Table 1, Table 1 of the.2008 edition); --- Increased the width and illustration of the width of the single side retaining ring (see 5.1); --- Increased the minimum thickness of the wheel retaining ring (see Table 7); --- Modified the diameter of the bend of the retaining ring (see 5.3, 4.3 of the.2008 edition); --- Revised the end face circular runout tolerance of the pulley with an outer diameter of 50.8mm or less (see 6.2, 5.1 of the.2008 edition); --- Modified the radial runout tolerance of the pulley with an outer diameter of 101.6mm or less (see 6.2, 5.2 of the.2008 edition); --- Modified the cylindricity and parallelism of the pulley, and increased the classification according to the wheel width (see 6.1, 6.3, 5.3, 5.4 of the.2008 edition); --- Increased pulley material, surface roughness and balance (see Chapter 7). This standard uses the redrafting method to modify the use of ISO 5294.2012 "synchronous belt drive pulley". This standard has more structural adjustments than ISO 5294.2012. Appendix A lists this standard and ISO 5294.2012. The chapter number is compared to the list. There are technical differences between this standard and ISO 5294.2012, and the terms involved in these differences have been passed through the margins on the outer side of the page. The vertical single line (|) is marked, and a list of the corresponding technical differences and their causes is given in Appendix B. This standard has made the following editorial changes. --- Changed the standard name to harmonize with existing standards in China; --- Removed parameters and tolerances in inches. This standard was proposed by the China Machinery Industry Federation. This standard is under the jurisdiction of the National Technical Committee for Pulley and Belt Standardization (SAC/TC428). This standard was drafted. Shijiazhuang Kaipu Power Transmission Machinery Co., Ltd., Sichuan Deen Precision Technology Co., Ltd., machine Mechanical Science Research Institute Group Co., Ltd., China Machine Productivity Promotion Center, Ningbo Fengmao Far East Rubber Co., Ltd., Ningbo Kaichi Tape Co., Ltd. the company.
