Abstract
The utility model discloses a flywheel convenient to process. The flywheel comprises a flywheel body, a connection disk and an outer flywheel, wherein a plurality of through holes of the same size are arranged on side sections of the flywheel body, the connection disk and the outer flywheel respectively, the flywheel body is connected to the connection disk through bolts, and the connection disk is connected to the outer flywheel through bolts. According to the technology of diesel flywheel structure modification, the flywheel is produced through the connection in an assembly mode. The weight of a prior flywheel is reduced, the structure of the prior flywheel is simplified, casting defects during casting are reduced, waste products are controlled effectively, the cost is saved, subsequent machining and clamping are facilitated, the disassembly and the maintenance are convenient, and integral performance requirements of internal-combustion engine flywheels are met.
Description
Technical field
The utility model is particularly related to a kind of flywheel easy to process.
Background technique
Flywheel is the vital part of internal-combustion engine, and its function is to regulate the I. C. engine crankshaft rotation speed change, plays stabilized (steady-state) speed, is conducive to simultaneously the startup of internal-combustion engine, is conducive to piston and passes through smoothly up and down stop.The blank of this part is foundry goods, the casting defects such as foundry goods must not require crackle, shrinkage porosite, slag inclusion.Simultaneously do not allowed any casting defect for important finished surface, the quality of its quality is directly connected to the quality of complete machine.S1005116-1090 flywheel in the BF6M1013-21T2-1090 model motor of Dao Yici (vapour) Dalian Diesel Engine Co., Ltd is as example, the thickness size of the former project organization of its fly wheel assembly reaches 131.4mm, the round-corner transition place changes greatly, casting defect in the casting and pouring process, occurs easily, and follow-up mechanical processing difficulty is larger.
Summary of the invention
Goal of the invention: in order to solve the technical problem that exists in the above-mentioned background technology, provide a kind of flywheel easy to process.
The technological scheme that adopts: a kind of flywheel easy to process comprises: flywheel 1, land 2, outer flywheel 3; The side section of land 2, flywheel 1 and outer flywheel 3 is respectively equipped with the identical through hole of some sizes, and flywheel 1 is connected with land 2 by bolt; Land 2 is connected with outer flywheel 3 by bolt.
Beneficial effect: the utility model is the technology about the diesel engine flywheel architecture advances, adopt the mode of assembly parts to link together to replace a kind of flywheel, can make original flywheel weight saving and designs simplification, reduce the generation of the casting defect in the casting process, can effectively control the generation of waste product, save cost; Be conducive to follow-up processing and loading clamp, and detachable maintaining is comparatively convenient, has satisfied the overall performance requirement of internal combustion engine flywheel.
Description of drawings
Fig. 1 is the structural representation of a kind of flywheel easy to process of the utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is elaborated.
Accompanying drawing sign: 1-flywheel, 2-land, the outer flywheel of 3-.
A kind of flywheel easy to process of the utility model comprises: flywheel 1, land 2, outer flywheel 3; The side section of land 2, flywheel 1 and outer flywheel 3 is respectively equipped with the identical through hole of some sizes, and flywheel 1 is connected with land 2 by bolt; Land 2 is connected with outer flywheel 3 by bolt.
Through the tracking to casting process, can find out in the statistical analysis of foundary loss rate before the utility model and the architecture advances, reject rate before the architecture advances is 7.68%, and reject rate of the present utility model is 2.36%, the utility model is conducive to casting process optimization, effectively reduce the foundary loss rate of workpiece, saved cost; Be conducive to machining, the clamping workpiece fast and easy.
