Abstract
The utility model discloses a transmission shaft shell with a fixing lug. The transmission shaft shell with the fixing lug comprises a big cylindrical shell and a small cylindrical shell, wherein the big cylindrical shell is a main motor installation frame, the small cylindrical shell is a transmission shaft installation frame, the big cylindrical shell and the small cylindrical shell are cast to form an integral body, transition between the big cylindrical shell and the small cylindrical shell is achieved through stepped holes, the big cylindrical shell and the small cylindrical shell are communicated with each other, a radial through hole is formed in the outer wall of the big cylindrical shell, the fixing lug is further arranged on the outer wall of the big cylindrical shell, a fixing hole is formed in the fixing lug, an open pore is formed in the outer wall of the small cylindrical shell, and a plurality of screw holes are formed in the inner wall of the big cylindrical shell. According to the transmission shaft shell with the fixing lug, the structure is reasonable, installation efficiency and production efficiency are further improved due to the fact that the main motor installation frame and the transmission shaft installation frame are cast into a whole, accuracy of connection between a main motor and a transmission shaft is improved, and the service life is further prolonged.
Description
Technical field
The utility model relates to the assembly of capstan head machining center chair mechanisms, is specifically related to a kind of fixedly transmission shaft shell transmission shaft shell of ear that has.
Background technology
