Abstract
The invention provides an efficient split type 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 the central shafts, the crank section shaft, and the connecting plates are fixedly connected through connecting bolts; one ends of the connecting plates are connected with the central shafts, and the other ends of the connecting plates are connected with the crank section shaft.
Description
Technical field
The present invention and a kind of engine crankshaft, specifically a kind of efficient split type bent axle.
Background technique
At present, so the phase angle between 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 efficient split type bent axle.
In order to solve the problems of the technologies described above, a kind of efficient split type bent axle of the present invention, comprises central shaft, opposite opened central shaft bearing support, tune axle, the connecting plate between tune axle and central shaft, is characterized in that, described central shaft, tune axle, connecting plate, is to be fixedly connected with by connecting bolt, 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 being bolted between each shaft part and connecting plate, phase angle between can each crankshaft section of adjustment for convenience detach, and change rolling bearing.
