For the automobile of front-engine rear-drive, as power-actuated vitals, front end is with transmission output shaft even for power transmission shaft
Connect, rear end is connected with back axle.Traditional power transmission shaft and transmission output shaft generally adopt spline connection although easy to assembly, but
Driving torque is less, and noise is larger.For obtaining larger driving torque and reducing drive noise, some employing flexible couplings are even
Connect, one end of flexible coupling is connected with the rear end of variator by ring flange, the other end passes through the front end of ring flange and power transmission shaft
Connect, be then fastened by bolts respectively.Be fastened by bolts tighten with moment of torsion when, power transmission shaft can occur the phenomenon of transfer,
Have by put into gear so that gearbox gear engagement although can assembling when mitigate power transmission shaft transfer, but gearshift can be made to draw
Rope is connected difficulty with selector；Power transmission shaft is still fixed with handss by great majority using a people, the mode of another person's fastening bolt
Assembled.But it is the increase in cost of labor, and physical demandss are big, split run is produced with the production line of hundreds of automobile, work people
The labor intensity of member is quite big, and also has higher requirement to the tacit cooperation of assembly crewman；How to reduce artificial one-tenth
This, improve assembling convenience, improve production efficiency, ensures assembling quality, has become a difficult problem to be solved during assembling.
CN205184632U disclosed " a kind of rotation-preventing mechanism for differential mechanism and power transmission shaft fastening ", including：Limited block
The positioning being used on fixture as pedestal；Sleeve is located in the top of described limited block；Ratchet spanner, described ratchet spanner with
One end that described sleeve protrudes from described limited block connects, for sleeve described in one-directional rotation；Fairlead is set in described sleeve
Protrude from the other end of described limited block, and described fairlead is fixed on described limited block；Tight with power transmission shaft for differential mechanism
Solid rotation-preventing mechanism structure, design is simple, easy to use it is adaptable to need to fasten the back axle of differential mechanism and drive shaft bolt.
This structure substantially increases the qualification rate that moment of torsion tightens it is ensured that product quality.But this structure is not suitable for transmission output shaft
Fastening with power transmission shaft.
Content of the invention
The purpose of this utility model is to provide a kind of anti-rotating tooling for transmission output shaft and power transmission shaft fastening, its energy
Enough avoid when fastening transmission output shaft with power transmission shaft, the phenomenon of transfer in power transmission shaft；Have good intensity, rigidity and
Corrosion resistance；Cost of labor can be reduced, easy to use, it is possible to increase assembling convenience, improve production efficiency, ensure assembling matter
Amount.
A kind of anti-rotating tooling for transmission output shaft and power transmission shaft fastening described in the utility model, including frock originally
Body, is characterized in that：Described frock body is in Y-shaped, is made up of trigger piece and connected two spanners, the end of described spanner
It is provided with the through hole of dodecagon.
Further, the angle between described two spanners is 45 degree.
Further, the length of side of described through hole is 19 millimeters.
Further, the length of described trigger piece be 200 millimeters, width be 20 millimeters, thickness be 12 millimeters, the length of described spanner
Spend for 75 millimeters.
Further, described trigger piece and spanner are to be welded to connect.
Further, the material of described trigger piece and spanner is 06Cr19Ni10.
The beneficial technique effect of this utility model：
Because frock body is in Y-shaped, it is made up of so that tight with power transmission shaft in transmission output shaft trigger piece and two spanners
Gu when, it is to avoid the phenomenon of power transmission shaft transfer；Because the design of trigger piece and spanner size is so that have good intensity, rigidity
And corrosion resistance；Meanwhile, reduce cost of labor, easy to use, improve assembling convenience, improve production efficiency, ensure
Assembling quality.
Brief description
Fig. 1 is structural representation of the present utility model；
Fig. 2 is working state schematic representation of the present utility model.
In figure：1- trigger piece, 2- spanner, 3- power transmission shaft, 4- flexible coupling, 5- first connecting bolt, 6- second connecting bolt.
Specific embodiment
Below in conjunction with drawings and Examples, this utility model is elaborated.
A kind of anti-rotating tooling for transmission output shaft and power transmission shaft fastening shown in Figure 1, including frock body,
It is characterized in that：Described frock body is in Y-shaped, is made up of trigger piece 1 and connected two spanners 2, the end of described spanner 2
It is provided with the through hole of dodecagon.Frock body is in Y-shaped, is made up of two spanners 1 and trigger piece 2, spanner 2 and double offset ring spanner
Spanner similar so that when fastening transmission output shaft and power transmission shaft, it can be avoided that the phenomenon of transfer in power transmission shaft.
Angle between described two spanners 2 is 45 degree.
The length of side of described through hole is 19 millimeters.
The length of described trigger piece 1 is 200 millimeters, width is 20 millimeters, thickness is 12 millimeters, and the length of described spanner 2 is
75 millimeters.Trigger piece 1 and spanner 2 size be designed to so that this frock has good strength and stiffness, ensure work simultaneously
Librarian use is convenient, is unlikely to weigh very much.
Described trigger piece 1 and spanner 2 are to be welded to connect.
