Background technique
When in use, the rod journal of crankshaft is connect crankshaft with piston rod, based on the up and down motion transformation of piston rod
The rotation of axis, crankshaft in rotation because being that piston brace rod moves up and down to be converted into the rotary motion of main shaft, even
It under the gravity of bar and crank arm, is easy to cause the velocity of rotation of crankshaft unstable, is easy to happen concussion, accelerates crankshaft
Damage, the dynamic instability of conveying, the stress of piston rod or other attachmentes can be between crank and axle journal when due to using
Knuckle at concentrate, be easy to cause crankshaft at knuckle to crack in this way, crackle to generation and the crankshaft to fracture
It is replaced, changes new crankshaft, substantially increase repair cost in this way.
Summary of the invention
It is to be solved by this invention the purpose of this utility model is to overcome above-mentioned the shortcomings of the prior art place
Technical problem is the situation for the prior art, provides a kind of a kind of compact overall structure reasonably crankshaft structure.
The technical solution adopted in the utility model are as follows: the crankshaft structure, including crank, maneton and crank, it is described
The two sidewalls of crankshaft are equipped with crank, and shoulder is turned in semicircular in the junction of the crankshaft and crank, and the one of the crank
Side is equipped with maneton, is respectively provided with one group of hemispherical protuberances reinforcing rib on four corners of the maneton, described is hemispherical convex
The periphery for playing reinforcing rib is equipped with pulling force rib, and one end of the pulling force rib is connected to the side on crank, institute by fixed fixture block I
The other end for the pulling force rib stated is connected on one end of maneton by fixed fixture block II, the two sides of the inner cavity of the maneton
Between be equipped with several equidistant reinforced steels, the diagonal angle of the maneton inner cavity, which is connected, is connected to enhancing muscle, the song
Upper and lower ends wall in axis is equipped with wearing layer, and the inner wall of the wearing layer is equipped with buffer layer.
Described turning is equipped with enhancing block in shoulder, the enhancing block is square steel structure.
Waterproof layer is coated on the lateral wall of the maneton.
The reinforced steel is fixed by welding on the two sidewalls of maneton inner cavity.
The beneficial effects of the utility model are: the hemispherical protuberances reinforcing rib on four corners for passing through maneton can be enhanced
The toughness of knuckle between crank and axle journal, prevents crackle, passes through the pulling force of hemispherical protuberances reinforcing rib periphery
Muscle can play the role of load, reduce the damage to hemispherical protuberances reinforcing rib, by the reinforced steel of maneton inner cavity and
Enhancing muscle can reinforce the structural strength of maneton, improve cushion performance and shock resistance, improve the service life of crankshaft, drop
Low repair cost.
Detailed description of the invention
Fig. 1 is the utility model structure diagram.
Fig. 2 is the partial structure diagram of the utility model.
Specific embodiment:
The attached figures are only used for illustrative purposes and cannot be understood as limitating the patent；In order to better illustrate this embodiment, attached
Scheme certain components to have omission, zoom in or out, does not represent the size of actual product；To those skilled in the art,
The omitting of some known structures and their instructions in the attached drawings are understandable.
Referring to attached drawing, the crankshaft structure, including crankshaft 2, maneton 4 and crank 3, on the two sidewalls of the crankshaft 2
Equipped with crank 3, shoulder 1 is turned in semicircular in the junction of the crankshaft 2 and crank 3, and the side of the crank 3 is equipped with crankshaft
Neck 4 is respectively provided with one group of hemispherical protuberances reinforcing rib 9, the hemispherical protuberances reinforcing rib on four corners of the maneton 4
9 periphery is equipped with pulling force rib 12, and one end of the pulling force rib 12 is connected to the side on crank 3, institute by fixed fixture block I5
The other end for the pulling force rib 12 stated is connected on one end of maneton 4 by fixed fixture block II8, the inner cavity of the maneton 4
Two sides between be equipped with several equidistant reinforced steels 6, the diagonal angle of 4 inner cavity of maneton, which is connected, is connected to enhancing muscle 7,
Upper and lower ends wall in the crankshaft 2 is equipped with wearing layer 11, and the inner wall of the wearing layer 11 is equipped with buffer layer 10.
Described turning is equipped with enhancing block in shoulder 1, the enhancing block is square steel structure.
Waterproof layer is coated on the lateral wall of the maneton 4.
The reinforced steel 6 is fixed by welding on the two sidewalls of 4 inner cavity of maneton.
Specific implementation process is as follows: by welded connecting reinforced steel 6 on the two sidewalls of the inner cavity of maneton 4, and
The diagonal angle of inner cavity is equipped with hemispherical protuberances reinforcing rib by being welded to connect enhancing muscle 7, in the junction of maneton 4 and crank 3
9, it is equipped with pulling force rib 12 in the periphery of hemispherical protuberances reinforcing rib 9, the both ends of pulling force rib 12 pass through fixed fixture block I5 and fixing card
Block II8 is separately fixed on crank 3 and maneton 4, and structural behaviour is strong, and stability is high.
