Specific embodiment
In order to further explain the technical solution of the present invention, being explained in detail below by specific embodiment the present invention
It states.
Fig. 1, Fig. 2 and Fig. 3 are please referred to, present invention discloses a kind of power takeoff shells comprising there is shell 10 and setting to exist
Gear chamber 20 inside shell 10, the gear chamber 20 have with the engine seating side 30 that reclines of installation and with peace
The corresponding assembling side 40 in side 30 is filled, the seating side 30 and assembling side 40 are respectively arranged with for driving shaft setting
First shaft hole 1, the second axis hole 2 and multiple bolt sleeves that seating side 30 is extended to by assembling side 40 for transmission shaft setting
Column 3.
Power takeoff shell of the present invention is provided with multiple bolt sleeve columns 3 that seating side 30 is extended to by assembling side 40；Institute
Power takeoff shell is stated to be fitted together by wearing the protrusion seating side 30 of bolt sleeve column 3 from assembling side 40 with cluster engine；By
It is to extend to seating side 30, the height of bolt sleeve column 3 and the height one of gear chamber 20 by assembling side 40 in bolt sleeve column 3
It causes, stay bolt can securely fit together entire shell 10 and engine when locking, and package assembly is stronger；And bolt sleeve
Column 3 is that directly from assembling side 40, lock sets stay bolt, without pass through gear chamber 20, is installed more convenient simple.
The bolt sleeve column 3 of the invention, which has, is symmetricly set on 1 two sides of first shaft hole and close to 20 bottom of gear chamber
The first sleeve column 31 and multiple be looped around second sleeve column 32 of the first shaft hole 1 far from 2 side of the second axis hole；Two first sleeve columns
31 and multiple second sleeve columns 32 composition decorateeed around multiple groups of the periphery of first shaft hole 1, can be by power takeoff shell and engine jail
Admittedly fitting together, also guarantee engine power stablizes output.
There are three second sleeve column 32 settings of the invention and is respectively distributed on the concentric circles of first shaft hole 1；And by
It is not connected to gear chamber 20 in the bolt sleeve column 3, therefore when locking stay bolt, without using gasket seal.
The first shaft hole 1 of the invention is provided with the bolt hole of multiple circular first shaft holes 1 close to 2 side of the second axis hole
Group 4, the second spiral shell that the bolt hole group 4 has the first bolt hole 41 for being set to seating side 30 and is set to assembling side 40
Keyhole 42；And the center line that first bolt hole 41 and the second bolt hole 42 are located at is parallel with the axis of first shaft hole 1；Short
