Embodiment 1
As shown in Figs. 1-2, the utility model provides a kind of star-wheel worm pump star-wheel work knuckle-tooth mounting structure, including the pump housing 1,
The side of the pump housing 1 is provided with star-wheel removal hole 2, and the side of star-wheel removal hole 2 is provided with multiple star-wheel mandrels 3, star-wheel mandrel 3
Interior side is provided with star-wheel hub 4, and the side of star-wheel hub 4 is provided with star-wheel tooth 5, and the interior side of star-wheel tooth 5 is provided with locking
The bottom side of pin 6, locking pin 6 is provided with compressed spring 7, and the bottom of compressed spring 7 is provided with pump frame 8.
The side of star-wheel hub 4 is provided with cylindrical hole 9, and the side of cylindrical hole 9 is provided with star-wheel hub lock hole 10, cylindrical hole 9
The fixed installation to star-wheel tooth 5 can be achieved, there is good using effect.
The top of locking pin 6 is set as cone, and the lower part of locking pin 6 is set as cylindrical, cone and cylinder
Moulding is conducive to locking pin 6 and is fixed and dismantles, and improves using effect.
The upper cone face of locking pin 6 is inserted by the pressing force of compressed spring 7 in the cylindrical hole 9 of star-wheel hub 4, entirely
Spider member, which is mounted on the structure in the pump housing, real can quickly disassemble and install star-wheel knuckle-tooth, while whenever not ensure
It is that loose or dislocation phenomenon occurs, there is good using effect.
Specifically, when using the utility model, when installation, first star-wheel tooth 5 is mounted on star-wheel mandrel 3, it then will pressure
Contracting spring 7 is placed in the cylindrical hole 9 of 4 bottom side of star-wheel hub, then locking pin 6 is placed on above compressed spring 7, will lock
Star-wheel mandrel 3 is mounted on after being pressed into cylindrical hole 9 in the hole of star-wheel hub 4 by pin 6, rotation star-wheel mandrel 3 is provided, when locking pin 6
After being directed at the star-wheel hub lock hole 10 on star-wheel hub 4, locking pin 6 is inserted into star-wheel hub lock hole 10 under spring force, will
Star-wheel mandrel 3 and star-wheel tooth 5 are locked on star-wheel hub 4, and when dismounting, star-wheel hub 4, which is rotated to star-wheel hub lock hole 10, the pump housing
Star-wheel removal hole 2 on 1 is aligned, and locking pin 6 is pressed into 3 cylindrical hole 9 of star-wheel mandrel with tool, makes locking pin 6 and star-wheel hub
Lock hole 10 is detached from, rotation star-wheel mandrel 3, you can is removed star-wheel mandrel 3, and then is removed star-wheel tooth 5, when needing to dismantle knuckle-tooth
When, only lower bolt is pushed up from wheel hub top, you can remove knuckle-tooth.
Skill therein is：The hole position on hole position and wheel hub on circle handle is slightly offset, and makes a secondary card of bolt circular conical surface
