Abstract
The invention discloses a novel transmission shaft connecting flange. The novel transmission shaft connecting flange comprises a tensioning flange base, inside hexagonal tensioning bolts, a tensioning flange and shaft coupling bolts. The tensioning flange base is arranged on a rotating shaft in a sleeving mode, the tensioning flange is arranged on the tensioning flange base in a sleeving mode, and the tensioning flange base and the tensioning flange are fixedly connected through the inside hexagonal tensioning bolts. The shaft coupling bolts are connected to the tensioning flange in a threaded mode. According to the novel transmission shaft connecting flange, the tensioning flange base and the rotating shaft are matched in a surface-and-surface mode. A tooth-and-tooth engaging mode of a traditional spline is eliminated, transmission efficiency is improved, self stress of parts is increased, surface-and-surface matched torque transmission is evener compared with the traditional spline, and transmitted torque is larger. In the novel transmission shaft connecting flange, the tensioning flange base and the tensioning flange are easy to machine and are each of an unthreaded surface structure, the machining process is greatly simplified, machining cost is lowered, and the transmission safety of the system is improved.
Description
Technical field:
The present invention relates to a kind of New-type transmission shaft adpting flange.
Background technique:
On automobile, general power coupling conventional method adopts spline joint to be coupled.Power output (initiatively output shaft) end is external splines or internal spline, and the driven shaft matched with it adopts internal spline or external splines to be coupled.
When not improving material and processing technique, there is following defect in conventional spline:
1) processes is complicated--and no matter the processing of spline is rectangular spline or involute splines, and processing technology is all very complicated, and machining accuracy is high, and in course of working, yield rate is low.
2) cost--the technique complicated in course of working due to spline and lower yield rate, causing spline processing cost higher, there is this problem in the internal spline matched with it or external splines equally.
3) no matter performance--conventional spline is involute splines or rectangular spline, and due to technique in course of working, the root circle of spline and top circle all can exist stress, at power, in torque drive process, brings hidden danger.
4) transmission efficiency-because spline is when being coupled, there is gap between internal spline and external splines, and need to lubricate, cause power can impact in the process of transmission, and, can transmission efficiency be reduced.
5) Security-spline is transmitting in the process of rotating, and can move axially.
Therefore, when not needing spline to move axially, needing to increase disconnecting prevention structure to spline, increase the complexity of technique further and increase cost.
