Description
Technical field
The utility model belongs to connection fork provision for disengagement among provision for disengagement technical field, more particularly to a kind of power transmission shaft.
Background technology
It is consumable accessory, it is necessary to periodically be changed to be driven shaft support, it is necessary to connect among first pulling down in Renewal process
Fork is connect, and the spline pair of middle connection fork and middle spline shaft is interference fit, removal force is very big.Due to power transmission shaft compared with
Long, central siphon is again relatively thin, is unfavorable for clamping in the equipment such as bench vice and dismantles, can only hold central siphon, and middle connect is tapped with hammer
Connect on the outside of fork fork, take out connection fork, not only arduously, and centre connection fork can be struck bad, influenceed after follow-up drive shaft cartridge matches somebody with somebody
Quality.The defects of present in existing unloading process, is as follows：1st, using traditional method for dismounting, clamping is difficult, no impetus；
2nd, middle connection fork surface is easily struck bad, influences the quality after follow-up drive shaft cartridge is matched somebody with somebody；3rd, unloading process is laborious, and labor intensity is big；
4th, the take-down time is grown, and makes power transmission shaft maintenance efficiency low.
The content of the invention
The purpose of this utility model is to overcome the shortcomings of the prior art, and provides connection fork among a kind of power transmission shaft
Provision for disengagement, by using special demounting device, can twist screw mandrel with spanner, and middle connection is easily taken out with the strength of screw mandrel
Part is pitched, does not damage middle connection fork, improves the speed of part exchanging.
The purpose of this utility model is completed by following technical solution, including power transmission shaft, screw rodb base, bottom plate, institute
The screw rodb base stated is fixed on the side of bottom plate, and tapped through hole is provided with the screw rodb base, passes through spiral shell in the tapped through hole
Rotation mode is connected with screw mandrel；Two support bars are fixed with the opposite side of described bottom plate, two support bars are in screw rodb base
Corresponding distribution, and be symmetric between two support bars with the shaft core line of screw mandrel；Described power transmission shaft is placed on,
And it is stuck on the outside of two forks of the middle connection fork in power transmission shaft on two support bars.
Preferably, the spacing being smaller than between two forks of middle connection fork between two described support bars.
Preferably, described power transmission shaft is made up of central siphon, intermediate support, middle connection fork, middle spline shaft, central siphon with
Middle spline shaft is integral by electric arc welding, and intermediate support is on middle spline shaft, the inner spline housing of centre connection fork
It is full of and is assemblied on the spline of middle spline shaft；The shaft core of middle spline shaft and the shaft core of screw mandrel are on same straight line.
The beneficial effects of the utility model are：According to the design feature and relative position relation of product parts, two are found
As a strong point on the outside of fork, and by the ability of wire rod thread transmission load, the revolving force of spanner is converted into silk
The axial force of bar, realize that a larger axial force completes disassembling for part；Solve and be stranded using traditional method for dismounting, clamping
Difficulty, the problem of no impetus；Eliminate middle connection fork surface and easily strike bad, influence the quality problems after follow-up drive shaft cartridge is matched somebody with somebody；
It is easily accomplished that unloading process is laborious, reduces the take-down time length of part, recall power transmission shaft maintenance.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Label in accompanying drawing is respectively：1st, central siphon；2nd, intermediate support；3rd, support bar；4th, middle connection fork；5th, middle spline
Axle；6th, screw rodb base；7th, bottom plate；8th, screw mandrel；61st, tapped through hole.
Embodiment
Detailed introduction is done to the utility model below in conjunction with accompanying drawing：As shown in Figure 1, the utility model includes transmission
Axle, screw rodb base 6, bottom plate 7, described screw rodb base 6 are fixed on the side of bottom plate 7, and are provided with tapped through hole in the screw rodb base 6
61, screw mandrel 8 is connected with by spiral way in the tapped through hole 61；Two branch are fixed with the opposite side of described bottom plate 7
Strut 3, two support bars 3 are in corresponding distribution with screw rodb base 6, and are in pair with the shaft core line of screw mandrel 8 between two support bars 3
Claim distribution；Described power transmission shaft is placed on bottom plate 7, and is stuck in two on the outside of two forks of the middle connection fork 4 in power transmission shaft
On support bar 3.The spacing being smaller than between two forks of middle connection fork 4 between two described support bars 3.
Described power transmission shaft is made up of central siphon 1, intermediate support 2, middle connection fork 4, middle spline shaft 5, central siphon 1 and centre
Splined shaft 5 is integral by electric arc welding, and intermediate support 2 is on middle spline shaft 5, the inner spline housing of centre connection fork 4
It is full of and is assemblied on the spline of middle spline shaft 5；The shaft core of middle spline shaft 5 is on same straight line with the shaft core of screw mandrel 8.
Unloading process of the present utility model is：Intermediate support 2 on middle spline shaft 5 is changed, it is necessary to first tear open
