GB/T 33520-2017Drive shaft T-section tooth (English PDF)

Foreword

This standard is drafted in accordance with the rules given in GB/T 1.1-2009.

This standard uses the re-drafting method to modify the use of ISO 12667..1993 "commercial vehicle and passenger straight drive shaft T-shaped flange fork".

The technical differences between this standard and ISO 12667..1993 are as follows.

- according to the parts industry on the use of T-shaped face teeth, the scope of expansion for the shaft with the shaft components;

- According to industry conditions and related standards consistency, the removal of the international standard in the normative reference documents;

--- According to the industry situation, modified the way mark.

This standard is proposed by the National Standard Committee on Machine Shaft and Accessories (SAC/TC109).

The drafting unit. Xuchang Far East Drive Shaft Co., Ltd., China Machine Productivity Promotion Center, Nanjing Super Spring Transmission Machinery Co., Ltd.

Division, Zhejiang Taishun of the metallurgical machinery parts factory.

1 Scope

This standard specifies the type and size of the T-shaped end teeth of the drive shaft.

This standard applies to the shaft parts of the drive shaft.

2 size and tolerance

The dimensions and tolerances of the T-shaped face teeth of the drive shaft are shown in Table 1, Figure 1 and Figure 2.

Table 1 units are in millimeters

a Due to special use, other size requirements may be made in the agreement between supply and demand.

b Verify that the pit L is the minimum clearance required to adjust the elements of the adjacent drive face teeth.

c for a certain purpose, may be required in the supply and demand agreement d1 = 122mm and 155mm.

d The current size of the current pit is 92 x 22. The new design of the drive shaft flange should not exceed that size.
