Description
Technical Field
The utility model relates to a bent axle especially relates to a balanced block structure can be dismantled to bent axle.
Background
The crankshaft is the most important part in the engine, and can bear the force transmitted by the connecting rod, and convert the force into torque to be output through the crankshaft and drive other accessories on the engine to work, and the existing crankshaft mainly comprises: the crankshaft journal comprises a plurality of crankshaft journals and connecting rod journals arranged between every two adjacent crankshaft journals, two ends of each connecting rod journal are connected with the corresponding crankshaft journal through cranks respectively, and balance blocks are arranged at the lower ends of the cranks. Because the connecting rod journal is at a certain distance from the crankshaft journal center, the two journals are not concentric, when the crankshaft rotates, the inertial mass of the piston and the connecting rod makes the crankshaft lose balance, a large unbalance force (centrifugal force) is generated, the unbalance force acts on the main journal, the load is increased, and in order to eliminate the unbalance, a balance weight needs to be arranged on the crank of the crankshaft. At present, the balancing piece all is structure as an organic whole with the crank, and the quality size can't be changed, in case the unbalanced value of bent axle is not up to standard in the test procedure, need rework again, in case the cylinder accident leads to the balancing piece to damage in case take place to smash moreover, that the bent axle is whole to be unable to use, needs whole change, and the replacement cost is high.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the technical problem that will solve is: provides a crankshaft detachable balance weight structure with a novel structure.
In order to solve the technical problem, the utility model discloses a technical scheme is: balance block structure can be dismantled to bent axle includes: the crankshaft type crankshaft comprises a plurality of crankshaft journals and connecting rod journals arranged between every two adjacent crankshaft journals, two ends of each connecting rod journal are respectively connected with the corresponding crankshaft journal through cranks, balance blocks are arranged at the lower ends of the cranks, upper flanges are symmetrically arranged on two sides of the lower ends of the cranks, lower flanges are symmetrically arranged on two sides of the upper ends of the balance blocks, the upper flanges and the lower flanges are connected through first connecting bolts and first connecting nuts, mounting grooves are symmetrically arranged on two sides of each balance block, a plurality of balance weight pieces are uniformly arranged in the mounting grooves, positioning columns are arranged in the middle of the mounting grooves, positioning holes matched with the positioning columns are formed in the middle of the balance weight pieces, second connecting bolts are symmetrically arranged in the mounting grooves on two sides of the positioning columns, and fixing holes matched with the second connecting bolts are formed in the balance weight pieces, the second connecting nut is fixedly connected with the second connecting bolt to fix the counterweight plate on the counterweight in the mounting groove.
The utility model has the advantages that: above-mentioned balanced block structure can be dismantled to bent axle, novel structure, install a plurality of detachable counterweight plates in the inside mounting groove in balancing piece both sides, can dismantle the regulation at any time in the testing process, thereby make the balanced value of bent axle can reach reasonable standard, the trouble of reworking has been saved again, the balancing piece adopts the components of a whole that can function independently structure with the crank simultaneously, can dismantle at any time, can change the balancing piece at any time when taking place to smash jar accident balancing piece and damage, need not to change whole bent axle, save the replacement cost.
