Be optimized according to above-mentioned, it is that steel part connects matrix that described nut connects matrix, through hole is arranged at the central authorities that steel part connects matrix, described basal body of nut is the zinc alloy basal body of nut, the zinc alloy basal body of nut forms at the through hole upper of the connection matrix of steel part, and both two-in-one form nut transmission matrixes.
Be optimized according to above-mentioned, the central authorities of described nut transmission matrix are provided with the mounting hole that matches and install with screw mandrel.
Be optimized according to above-mentioned, described mounting hole is provided with the screw thread that matches and install with screw mandrel.
The hole wall that described nut connects the through hole of matrix is provided with the spiral tooth, nut is connected on the outer wall of basal body of nut of through hole upper moulding of matrix form the spiral chute that matches with the spiral tooth.
Be optimized according to above-mentioned, described spiral tooth is connected the integrated setting of matrix with nut.
Perhaps, the hole wall that described nut connects the through hole of matrix is provided with spiral chute, makes on nut connects the outer wall of basal body of nut of through hole upper moulding of matrix and forms the spiral tooth that matches with spiral chute.
Be optimized described spiral tooth and the integrated setting of basal body of nut according to above-mentioned.
The utility model is its advantage of nut transmission that is used for screw rod transmission in prior art, it connects the through hole upper zinc alloy basal body of nut of matrix at steel part, make steel part connect matrix and zinc alloy basal body of nut two-in-one formation nut transmission matrix, reliable and practical, save the program that original nut connects matrix and making and the installation of the different component of basal body of nut, simplify production process, and the basal body of nut that the zinc alloy basal body of nut replaces original tin table copper spare to be made into has reduced fabricating cost.

Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
extremely shown in Figure 4 according to Fig. 1, nut transmission for screw rod transmission described in the utility model, its combination for the component of existing adpting flange and two unlike materials making of nut flange is installed, the making of the adpting flange of this unlike material and nut flange and supporting precision are all quite high, easily the products waste rate is high, have a strong impact on the service property (quality) of product, and also need bore junction of the edges of two sheets of paper screw after its two combinations installation and locate, because the intensity of unlike material is different, being difficult to support holds, easily destroy the component of these two unlike materials, the same reject rate that improves, and the existing brass bar truck system of generally using of this nut flange forms, this one-tenth is high, waste is large.
For above-mentioned situation, nut transmission of the present utility model, it includes nut and connects matrix 1, this nut connects in matrix 1 central authorities through hole, be provided with the basal body of nut 2 of moulding by casting on the through hole of this nut connection matrix 1, make basal body of nut 2 be connected the match nut transmission matrix 3 of being integral of composite casting of matrix 1 with nut, as shown in Figures 1 and 2.according to preferred forms, this nut connects matrix 1 and connects matrix for steel part, through hole is arranged at the central authorities that steel part connects matrix, and basal body of nut 2 is zinc alloy basal body of nut 2, zinc alloy basal body of nut 2 forms at the through hole upper of the connection matrix of steel part, be no more than under the operating mode of 150 degree in operating temperature due to zinc alloy, its every mechanical performance index is very near original brass spare, thereby zinc alloy basal body of nut 2 directly can be connected the through hole moulding by casting of matrix at steel part, both two-in-one, directly form the nut transmission matrix 3 of alloy composite part, the central authorities of nut transmission matrix 3 are provided with the mounting hole 4 that matches and install with screw mandrel, mounting hole 4 is provided with the screw thread 5 that matches and install with screw mandrel, as shown in Figures 2 and 3, thereby guarantee the matching gap of nut transmission matrix 3 and screw mandrel, when realizing that screw mandrel is driven by speed reducer, nut transmission matrix 3 rotates and moves along with screw mandrel, thereby make nut transmission matrix 3 of the present utility model effectively replace original two zero ones to make separately and install, simplify production process, and remove from and making and difficulty of processing, effectively improve product qualified rate, can extensive use when guaranteeing quality of product, reduce fabricating cost.
