Abstract
A flywheel casing provided with a gear installation chamber is mainly used for assembly of a large-size diesel engine. According to the flywheel casing provided with the gear installation chamber, a front end face and a rear end face of a cylinder body are respectively arranged on the front portion and the rear portion of the cylinder body, the cylinder body comprises a flywheel casing chamber and a gear chamber, a crankshaft timing gear is installed inside a crankshaft gear hole and is fixed through a crankshaft installation threaded hole, a cam shaft is installed inside a cam shaft gear hole and is fixed through a cam shaft installation threaded hole, an oil pump is installed inside an oil pump gear hole and is fixed through an oil pump installation threaded hole, an idle gear is installed inside an idle gear hole and is fixed through an idle gear installation threaded hole, and the flywheel casing is fixed on the rear end face of the cylinder body through a flywheel casing installation threaded hole. The flywheel casing provided with the gear installation chamber eliminates secondary installation of a gear chamber and the related assembly process, lowers complexity of the assembly process, effectively prevents leakage and insufficient lubrication of an engine caused by a sealing problem of the gear chamber, relieves abradability of parts of the engine, and effectively lowers the failure rate of the engine and maintenance cost in the subsequent operation process of the engine.
Description
Technical field
The utility model relates to the Manufacturing Technology for Automotive Parts field, specifically a kind of flywheel casing with the gear installation room of motor.
Background technique
At present, high-power diesel engine is in running, and each moving parts all is used on another part with certain masterpiece, and relative movement at a high speed occurs, and part surface must produce friction, accelerates parts depreciation.Therefore, in order to alleviate wearing and tearing, reduce surface friction drag, increase the service life, all must be furnished with associated lubrication system on the motor.All adopt independent gear chamber that the installation carrier of engine lubrication system is provided on the motor at present, the gear chamber that is equipped with the parts such as crankshaft timing gear, camshaft gear wheel, oil pump, sloth wheel gear is smeared sealer with flywheel casing and is connected, flywheel by flywheel casing inside drives cogged normal operation, but has following drawback.
1, because the accuracy of manufacturing problem causes lubricating system and flywheel to be equipped with the gap, strengthens the wearing and tearing of the part of each relative movement, increased cost and the rate of fault of later maintenance.
2, the independent gear chamber usability of installing is poor.Independent gear chamber of installing relates to secondary seal, at first be gear chamber with the sealing between the cylinder body, secondly be the sealing between gear chamber and the flywheel casing, increase the risk of revealing.In case reveal, the integral body that affects motor is lubricated, accelerate the wearing and tearing of part and the maintenance cost in later stage.
3, the overall cost of motor of independent installation gear chamber is higher.Because independent gear chamber must realize and being connected of cylinder body by external fastening, so just needs to increase extra cost; Secondly in installation process, must carry out secondary installing, cause the increase of assembling set, thereby whole motor cost be high.
4, the independent weak point in working life that gear chamber is installed.Owing to adopt secondary installing, in use, particularly in the bad situation of working condition, when engine vibration is larger, cause easily the problems such as construction bolt is loosening, the day by day looseness between the gear has strengthened the risk of leakage of oil and noise.
Summary of the invention
For overcoming the deficiencies in the prior art, goal of the invention of the present utility model is to provide a kind of flywheel casing with the gear installation room, improves engine performance stability to reach, and reduces the motor energy consumption, and the purpose that reduces cost.
For achieving the above object, forward and backward front-end face and the ear end face of being distributed with of cylinder body of the present utility model, it is characterized in that: cylinder body comprises flywheel casing chamber and gear chamber, crankshaft timing gear is installed in the crankshaft gear hole, fixes by the crankshaft installed tapped hole; Camshaft is installed in the camshaft gear wheel hole, by camshaft tapped hole is installed and is fixed; Oil pump is installed in the oil pump gear hole, by oil pump tapped hole is installed and is fixed; Idle gear is installed in the idle gear gear hole, by idle gear tapped hole is installed and is fixed; The flywheel casing assembly is installed tapped hole by flywheel casing and is fixed on the ear end face of cylinder body.
The utility model compared with prior art has following advantage.
Because the fit up gap that machining accuracy causes has dwindled the normal operating wear extent of gear, reduced cost and the rate of fault of follow-up motor operation maintenance when 1, cast-in-block gear chamber and flywheel casing chamber have avoided independent gear chamber to install.
2, avoid the secondary installing of gear chamber with the flywheel casing of gear installation room, removed the coating process in the secondary installing process, saved the bolt that installs and fixes of gear chamber, reduced complexity and the assembly cost of the assembly technology of motor.
3, avoid the independent of gear chamber to install with the flywheel casing of gear installation room, avoided the faults such as leakage of oil that motor causes because of gluing problem and bolt looseness and noise in follow-up operation process, reduced assembly cost and breakdown in the motor rate.

Embodiment
Such as Fig. 1, Fig. 2, shown in Figure 3, be distributed with front-end face 2 and ear end face 3 in the front and back of cylinder body 1; Cast out flywheel casing chamber 4 and gear chamber 5 in the flywheel casing casting process, crankshaft timing gear is installed in the crankshaft gear hole 6, by crankshaft installed tapped hole 7 is fixing on every side; Camshaft is installed in the camshaft gear wheel hole 8, and is fixing by the tapped hole 9 of camshaft installation on every side; Oil pump is installed in the oil pump gear hole 10, and it is fixing by the peripheral plane oil pump tapped hole 11 to be installed; Idle gear is installed in the idle gear gear hole 12, and it is fixing by peripheral idle gear tapped hole 13 to be installed; The flywheel casing assembly is installed tapped hole 14 by flywheel casing and is fixed on the ear end face 2 of cylinder body.
During work, the flywheel in the flywheel chamber drives idle gear and rotates, and idle gear drives the runnings such as oil pump, crankshaft timing gear, camshaft gear wheel, finally drives lubricant oil moving in circles in each lubricating system.
