Abstract
The invention discloses a split type high torque crank shaft which comprises central shafts, split central shaft bearing seats, a crank section shaft and connecting plates between the crank section shaft and the central shafts, and is characterized in that regular polygon steps are formed in the shaft end faces of the central shafts and the crank section shaft by taking the shaft axes as centers; socket regular polygon holes, corresponding to the regular polygon steps, are formed in the connecting plates; the central shafts and the crank section shaft are fixed on the other faces of the connecting plates through gaskets and bolts; the central shafts are connected with one ends of the connecting plates, and the crank section shaft is connected with the other ends of the connecting plates.
Description
Technical field
The present invention relates to a kind of engine crankshaft, specifically a kind of split type high moment of torsion bent axle.
Background technique
At present, so the phase angle between the each tune axle of conventional engines bent axle is the non-removable employing split bushing of fixing, and join oil pump and constantly between bearing shell and tune axle, pump into lubricant oil, because be sliding friction between bearing shell and tune axle, energy consumption is large, because the phase angle between tune axle is fixing, can not adjust by people's desired phase angle in addition.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of split type high moment of torsion bent axle.
In order to solve the problems of the technologies described above, split type high moment of torsion bent axle of the present invention, comprise central shaft, opposite opened central shaft bearing support, tune axle, connecting plate between tune axle and central shaft, it is characterized in that described central shaft arranges regular polygon step centered by shaft axis in the axial end of tune axle, the socket joint regular polygon hole corresponding with regular polygon step is set on connecting plate, another side at connecting plate passes through pad, and bolt is by central shaft, and tune axle is fixed on connecting plate, one end of connecting plate connects central shaft, and the other end connects tune axle.
On described central shaft and tune axle, rolling bearing is installed, the bearing outer ring on central shaft is fixed in opposite opened central shaft bearing support, and the bearing outer ring on tune axle is fixed in the split box cover of connecting rod.
Adopt the design's beneficial effect to be: all sliding friction sections on original bent axle have been made into rolling friction, cancelled oil pumping system, made motor Energy Intensity Reduction, cost has also reduced, in addition owing to passing through the peripheral surface transmitting torque of the regular polygon step of axle head separately between each shaft part and connecting plate, lifting surface area is larger, so energy transmitting large torque, the benefit also having is, because each shaft part and connecting plate are bolted, phase angle between can the each crankshaft section of adjustment for convenience detach, and change rolling bearing.
