Fixture block matches with the sliding slot, and the fixture block is slidably arranged in the sliding slot, and the spring is arranged in the sliding slot and institute
It states between fixture block, the clump weight is arranged in the guide groove, is provided on the clump weight and matches with the locating slot
Locating piece, the locating piece, which is slidably arranged in, to be opened up on the locating piece and the contact surface of the locating slot in locating slot
There is card slot, one end of the fixture block is fastened in the card slot.Clump weight is arranged in the locating slot of different location in guide groove
It is interior, to just change the rotary inertia of flywheel at runtime, meet the requirement of different occasions.
Clump weight further includes further fixed block and connecting rod, the wheel disc edge in the axial displacement of wheel disc in order to prevent
Its radial direction offers limiting slot, and one end of limiting slot setting corresponding with the guide groove, the connecting rod is arranged described
On clump weight, the other end of the connecting rod passes through the limiting slot and is arranged on the fixed block, and the fixed block supports and is located at institute
It states on wheel disc.It is arranged on the clump weight of flywheel side by one end of connecting rod, while the other end setting of connecting rod is another in flywheel
On the fixed block of side, clump weight is effectively prevented in the axial displacement of wheel disc.
For the ease of the installation between fixed block and connecting rod, further, the fixed block and the connecting rod pass through nut
It is fixedly connected.Quickly fixed block and connecting rod can be fixed or loosened by controlling nut, thus quickly to clump weight position
It is adjusted.
In flywheel operation, in order to place fixture block due to inertia is detached from and sliding slot, further, two sides of the fixture block to
It is outer to extend the limited position shaft shoulder.Fixture block, which is effectively prevented, by the limit shaft shoulder of two sides detaches sliding slot.
The beneficial effects of the utility model are: the utility model DOHC engine with flywheel when in use, will
Clump weight is arranged in guide groove in the locating slot of different location, so that the rotary inertia of flywheel at runtime is just changed, it is full
The foot requirement of different occasions does not need to avoid available engine flywheel and needing different rotations flywheel disassembling with changing yet
When inertia, the flywheel of different model is needed replacing, and disassembles and installs that flywheel is relatively time-consuming to take a lot of work, reduces working efficiency, simultaneously
The problem of also increasing use cost.
