Detailed Description
In order to further explain the technical solution of the present invention, the present invention is explained in detail by the following embodiments.
As shown in fig. 1 to 6, the improved screw nut of the present invention includes an outer shell 1 and an inner inlay 2, the material of the inner inlay 2 is different from that of the outer shell 1, the inner inlay 2 can be made of a self-lubricating material, and the outer shell 1 is made of a steel material; a through hole 11 is formed in the outer shell 1, the inner inlay 2 is fixedly embedded in the through hole 11 of the outer shell 1, and a screw hole 23 is formed in the inner inlay 2.
Thus, the utility model relates to an improved generation screw nut produces through passing through shell body 1 and 2 two parts of inlay body with drive nut, shell body 1 with inlay body 2 makes through the material that adopts the difference, and inlay body 2 can adopt the material of wear-resisting low resistance performance to make like this, and the outer material that adopts the machining of being convenient for and structural strength preferred makes. Thus, the two parts of the outer shell 1 and the inner inlay 2 respectively make full use of the excellent performance of the respective materials, so that the improved transmission nut has better service performance and lower cost. The steel material makes shell body 1 have higher mechanical strength, makes things convenient for machining to attack operations such as tooth like punching, makes things convenient for shell body 1 and mechanical parts to be connected.
