Abstract
The utility model discloses a transmission shaft system for testing an engine rack, which comprises a transmission shaft. One end of the transmission shaft is connected with a transmission shaft in a ball cage shape which is connected with a dynamometer machine, the other end is connected with a front shaft through a bolt and a damping pad, and one end of the front shaft is provided with a first flange which is connected with an engine crank. Because the front shaft and a damping connector are additionally arranged between the engine crank and a connecting shaft, the transmission shaft can effectively reduce the large vibration brought by operating the engine and can prolong the service life.
Description
Technical field
The utility model relates to power drive mechanism, relates in particular to a kind of a kind of axial workpiece that is connected in engine and dynamometer machine when indexs such as engine output are tested, and this axial workpiece is installed on the engine pedestal.
Background technology
At present, motor car engine is comprised that petrol engine and diesel motor make a service test, general all is that tested engine is installed on the test-bed, by power drive mechanism the output power of the power output shaft of engine being transferred to dynamometer machine tests, in present bench test, the used transmission shaft of engine pedestal experiment utilizes flange one end at two ends and the flywheel of engine to fix, one end links to each other with the input shaft of dynamometer machine, aim at the dynamometer machine ease of connection in order to make engine, a rich property dish also is set sometimes, so that butt joint in the junction.The used threst stand of each motor car engine manufacturer adopts special material to make with the transmission shaft person now, production cost is than higher, and because vibrations are bigger when engine rig test, cause engine, transmission shaft or dynamometer machine to damage, cause serious economy loss.
In a word, the threst stand under the prior art can not reduce effectively with transmission shaft because the vibration that brings of engine running, and transmission shaft is damaged easily.
Summary of the invention
The purpose of this utility model provides a kind of engine rig test drive shaft system, uses this transmission shaft to slow down effectively because the great vibrations that engine running brings improves its serviceable life.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of engine rig test drive shaft system, comprise transmission shaft, transmission shaft one end connects the ball cage type transmission shaft that joins with dynamometer machine, the other end connects front axle by bolt and cushion blocking, and an end of described front axle links by first flange and engine crankshaft.
Further, be provided with protective cover by bearing on transmission shaft, described protective cover one end is near engine cylinder-body.
The good effect that the utility model produced is owing to increased a front axle and vibration damping connection between engine crankshaft and coupling shaft, can slow down the great vibrations of bringing owing to engine running effectively, the serviceable life of raising drive shaft system.Owing at transmission shaft and engine junction a protective cover is set, can masks part because the noise that engine brings.
Below with reference to accompanying drawing, comparatively detailed explanation is carried out in each preferred embodiment of the present utility model.
Description of drawings
Fig. 1 is that the utility model is connected structure cutaway view with engine with dynamometer machine.
Among the figure: 1. cylinder body, 2. flywheel, 3. bent axle, 4. first flange, 5. second flange, 6. coupling shaft, 7. front axle, 8. the 3rd flange, 9. screw, 10, bolt, 11, bearing, 12, cushion blocking, 13. ball cage type transmission shafts, 14. dynamometer machines, 15. protective covers.
Embodiment
As shown in Figure 1, a kind of engine rig test drive shaft system is sent to dynamometer machine with the power of engine and measures.This system mainly contains a transmission shaft 6, and an end of this transmission shaft 6 connects with engine crankshaft 3 by front axle 7, and the other end connects with dynamometer machine 14 by ball cage type transmission shaft 13.In engine cylinder-body 1 one sides, transmission shaft 6 by the concrete connected mode of front axle 7 and engine crankshaft 3 is, the cushion blocking 12 that installs bolt 10 and make at transmission shaft 6 one ends, a side that is connected with transmission shaft 6 at front axle 7 by rubber damping pad then be provided with by screw 9 fixedly sleeved on front axle 7 the 3rd flange 8.Utilize bolt 10 that the 3rd flange 8 and fastening cushion blocking 12 is fixing with transmission shaft 6.The other end of front axle 7 have with engine crankshaft 3 on engine flywheel 2 joining first flange, 4, the first flanges 4 be provided with second flange 5 between front axle 7 connects, first flange 4 and second flange 5 are passed through Bolt Connection.The purpose that is provided with second flange 5 is to reduce the difficulty of processing of flange.
In addition, can also be provided with protective cover 15 by bearing 11 on the transmission shaft 6, described protective cover 15 1 ends are near engine cylinder-body 1.Described bearing 11 1 ends have by the fastening bearing cap of screw.
Present embodiment has following advantage:
1, because transmission shaft is provided with the measure that reduces vibration in the middle of being connected with front axle, can significantly reduce vibration, increase the life-span of transmission shaft.
2, an end that links to each other with engine crankshaft at transmission shaft increases a protective cover, when preventing that dust from entering engine crankcase, has also reduced the pollution of noise to environment.
