Description
Technical field
It the utility model is related to a kind of bent axle, the chain saw bent axle specifically with counter weight device.
Background technology
Bent axle is the main rotation member of engine, and the up and down motion for accepting connecting rod becomes shuttling movement, and chain saw bent axle is one
The common chain saw actuating unit of kind, to balance high-speed rotating centrifugal force, it is necessary to carry out counterweight according to the actual requirements.
Utility model content
For above-mentioned deficiency, the purpose of this utility model is that, there is provided it is easy to install, have it is simple in structure, be applicable in
Property the strong chain saw bent axle with counter weight device.
To achieve the above object, the utility model provides following technical scheme：Chain saw bent axle with counter weight device, including a left side
Connecting shaft, left crank arm, right connecting shaft, right crank arm and the crank being arranged between left crank arm and right crank arm, left crank
Arm and right crank arm upper end are both provided with counter weight device, and counter weight device includes I-shaped fixed frame, and fixed frame bottom is provided with
Contiguous block, is respectively arranged with left and right step on the outside of left and right crank arm upper end, two contiguous blocks by bolt be separately fixed at it is left,
On the inside of right step, fixed frame on both sides of the middle is provided with several weight stacks, and weight stack is fixed on fixed frame by rivet.
The scheme further optimized, the left and right crank arm are socketed in left and right connecting shaft respectively, left and right crank arm
Left and right positioning pin is connected between left and right connecting shaft.
The utility model has an advantageous effect in that compared with prior art：The utility model is by increasing and decreasing the number of weight stack
Amount, or the weight of the weight stack change counter weight device using different-thickness, it is easy to install, there is simple in structure, adaptability
The characteristics of strong.
