Abstract
The utility model relates to a crankshaft for an automobile engine. The crankshaft comprises a front end and an output end, wherein a plurality of main journals are arranged between the front end and the output end; a power converting unit is arranged between the neighboring main journals. The crankshaft comprises two crank arms and one crank pin arranged between the two crank arms, wherein the crank pin is arranged at the upper ends of the two crank arms; an oil hole and an oil passage used for lubricating oil to pass are formed on the inner side wall of the crank arm; the main journals and the crank arms are integrally connected, or welded or fixedly connected through a fixing pin; and a counterbalance is arranged on the lower end surface of the crank arm. The crankshaft for the automobile engine has the advantage that the main journals and the crank arms are more firmly connected.
Description
Technical field
The utility model relates to a kind of actuating unit, particularly a kind of bent axle that is used for motor car engine.
Background technique
Engine crankshaft is one of topmost parts in the motor, its cost accounts for more than 60% of engine assembly basis, bent axle in the course of the work, piston rod pulling crank pin moves up and down, crankweb then drives main journal and rotates, therefore can bear axial load between crankweb and the main journal, being connected between crankweb and the main journal must be very firm, could guarantee the long-time use of bent axle.
Summary of the invention
The purpose of this utility model is to provide a kind of bent axle that is used for motor car engine at the problem of the bent axle existence of the existing motor car engine described in the background technique.
The realization the technical solution of the utility model is as follows:
A kind of bent axle that is used for motor car engine, it comprises front end and output terminal, between front end and output terminal, be provided with several main journals, be provided with power converting unit between the adjacent main journal, it comprises two crankwebs and a crank pin that is arranged between these two crankwebs, described crank pin is arranged at two crankweb upper ends, the crankweb interior sidewall surface is provided with oilhole and the oil duct that is used for the lubricant oil circulation, described main journal be connected with the crankweb one or weld or by fixing pin fixedly connected, the crankweb lower end surface is provided with equilibrium block.
The position that described main journal is connected with crankweb is provided with stiffening rib.
The beneficial effects of the utility model are because main journal of the present utility model is connected, welds with the crankweb one or connects by fixing pin, and the position that is connected with crankweb at main journal is provided with stiffening rib, so can effectively strengthen being connected between main journal and the crankweb, prevent the wearing and tearing of main journal and crankweb connection part, prolong the working life of bent axle.
Description of drawings
Fig. 1 is a schematic representation of the present utility model;
Among the figure, 1 is front end, and 2 is output terminal, and 3 is main journal, and 4 is crankweb, and 5 is crank pin, and 6 is equilibrium block, and 7 is stiffening rib, and 8 is oilhole.
Embodiment
With reference to a kind of bent axle that is used for motor car engine shown in the accompanying drawing 1, it comprises front end 1 and output terminal 2, between front end 1 and output terminal 2, be provided with several main journals 3, be provided with power converting unit between the adjacent main journal 3, it comprises two crankwebs 4 and a crank pin 5 that is arranged between these two crankwebs 4, described crank pin 5 is arranged at two crankweb 4 upper ends, crankweb 4 interior sidewall surface are provided with oilhole 8 and the oil duct that is used for the lubricant oil circulation, described main journal 3 be connected with crankweb 4 one or weld or by fixing pin fixedly connected, crankweb 4 lower end surfaces are provided with equilibrium block 6; For the position that main journal 3 is connected with crankweb 4 that is connected of further strengthening main journal 3 and crankweb 4 is provided with stiffening rib 7.Because main journal 3 of the present utility model is connected, welds or connect by fixing pin with crankweb 4 one, and the position that is connected with crankweb 4 at main journal 3 is provided with stiffening rib 7, so can effectively strengthen being connected between main journal 3 and the crankweb 4, prevent the wearing and tearing of main journal 3 and crankweb 4 connection parts, prolong the working life of bent axle.
