When equilibrium block is installed, mounting hole is aimed at attachment post, and cover is received on attachment post, be then plugged into by elasticity inserted sheet in the draw-in groove on attachment post, make elasticity inserted sheet lower end be connected on equilibrium block, the spring section of elasticity inserted sheet is connected on draw-in groove upper side wall.Mounting hole and the equal semicircular in shape structure of attachment post, therefore equilibrium block is plugged into after on attachment post and can not rotates again, ensures the stationarity connected.Realize the fastening of equilibrium block by elasticity inserted sheet, easy accessibility, connect reliable.This crankshaft counter balance mounting structure makes the easy accessibility of equilibrium block, and dismounting efficiency is high, and installation cost is low, operates steadily reliable after installation.
As preferably, equilibrium block comprises balance portion and joint, and balance portion is semi-annular shape structure, and joint is strip structure, and the thickness of joint is less than the thickness in balance portion, and mounting hole is arranged on joint, joint outer end semicircular in shape structure.Equilibrium block and attachment post easy accessibility.
As preferably, U-shaped elasticity inserted sheet opening end two madial wall is equipped with inwardly protruded spacing plush copper, U-shaped elasticity inserted sheet two end part all upwards bending tilt.Spacing plush copper makes the connection of elasticity inserted sheet more reliable.
As preferably, equilibrium block is provided with the counterweight hole be communicated with mounting hole, and counterweight hole opening becomes U-shaped structure.This vibrational power flow facilitates the dismounting of equilibrium block.
As preferably, attachment post upper end is provided with the oil-through hole be obliquely installed, and oil-through hole lower end extends through on bent axle, and bent axle outer wall is provided with the intercommunicating pore be communicated with oil-through hole.Oil-through hole facilitates the circulation of lubricant oil to lubricate.
As preferably, eccentric part comprises semicircular left side eccentric mass and semicircular right side eccentric mass, and left side eccentric mass diameter is greater than right side eccentric mass diameter, and attachment post is connected on the eccentric mass of right side.Eccentric part structure is arranged rationally, ensure that the stress balance in Crankshaft motion process.
Compared with prior art, the beneficial effects of the utility model are: crankshaft counter balance mounting structure makes the easy accessibility of equilibrium block, and dismounting efficiency is high, and installation cost is low, operate steadily reliable after installation.
