Further, described executing must firm internal thread part be nut or screw part.
Further, described threaded male component is for having externally threaded part, as bolt, axial workpiece etc.
Execute the parafacies ratio that must the jail be threaded with existing MJ screw thread, regular screw threads, the utility model provides executes the pair that must the jail be threaded and has better anti-fatigue performance and tensile strength, satisfies for tensile strength and fatigue strength has higher requirements and possess the needs of the application of anti-loosening property simultaneously.
Further specify the utility model below in conjunction with drawings and Examples.

Because executing that the utility model provides must be threaded secondary screw thread path greater than common internal thread path and MJ internal thread path, so radius of rounded root of the present utility model can be greater than the radius of rounded root of regular screw threads and MJ screw thread in the jail.Therefore the utlity model has than MJ screw thread and the better anti-fatigue performance of regular screw threads.
Wherein, execute firm to be threaded secondary internal thread and outside thread in the present embodiment and screw partial schematic diagram as shown in Figure 1.
The Bottom of Thread radius of arc figure that draws in proportion that the utility model is executed the outside thread 1 that must the jail be threaded among the secondary embodiment and existing two kinds of outside threads (MJ outside thread 2 and common outside thread 3) as shown in Figure 2.As can be seen from Figure 2, the utility model is executed the pair that must the jail be threaded and is had outside thread 1 than circular arc at the bottom of the molar, at the bottom of its tooth circular arc greater than the MJ screw thread, its can only with execute and must screw by firm screw thread.
Under the different span situations of pitch P, to compare with existing two kinds of screw threads, it is as shown in the table that Bottom of Thread circular arc of the present utility model increases percentage:
Because executing that the utility model provides must be threaded secondary screw thread path greater than common internal thread path and MJ internal thread path, so radius of rounded root of the present utility model can be greater than the radius of rounded root of regular screw threads and MJ screw thread in the jail.Therefore the utlity model has than MJ screw thread and the better anti-fatigue performance of regular screw threads.
The utility model screw bolt and MJ screw thread, regular screw threads bolt performance specifically are compared as follows table:
Above-described embodiment only is used to illustrate technological thought of the present utility model and characteristics, its purpose is to make those skilled in the art can understand content of the present utility model and implements according to this, can not only limit claim of the present utility model with present embodiment, be all equal variation or modifications of doing according to the spirit that the utility model disclosed, still drop in the claim of the present utility model.
