Description
Technical field
The utility model relates to a kind of belt sheave structure, relates in particular to a kind of belt sheave structure with the silicone oil vibration damper.
Background technique
On Traditional engine, often because annex too much or load is big or problem such as difficult arrangement, needs to arrange two-layer belt pulley.This just means that this belt pulley that is installed on the bent axle needs two, and perhaps two-layer belt pulley is made of one, and the entire length of motor has just increased like this.Participate in Fig. 1, an end of bent axle 3 is separately installed with first belt pulley 1 and second belt pulley 2, and the other end of bent axle 3 is installed on the motor, and the side near engine side 5 on the bent axle 3 also is provided with silicone oil vibration damper 4.The entire length of this device is bigger, and it is bigger to take up room, and is not easy to arrange and install.
Like Chinese utility model patent notification number: CN201420842Y; Open day: the utility model patent on March 10th, 2010 disclosed a kind of vibration damper belt wheel hub, belongs to field of mechanical technique, big, the bent axle Front oil seal leakiness wet goods problem of the difficulty of processing that it has solved existing vibration damper belt wheel hub; Vibration damper belt wheel hub; Comprise being discoidal body, said body center has and is connecting base cylindraceous, and the body center is stretched out in the connecting base end; The connecting base outside is with axle sleeve, and axle sleeve and connecting base are fixed together.But the vibration damper excircle of this device does not have the function of belt pulley, makes that the entire length of motor is bigger, the same defective that has layout and inconvenient installation.
Summary of the invention
The purpose of the utility model is on the bent axle of available engine two belt pulleys to be installed respectively; Entire length is bigger; Be not easy to the defective and the deficiency of arranging and installing; Provide a kind of simple in structure, the motor entire length reduces, the belt sheave structure of the band silicone oil vibration damper of being convenient to arrange and install.
For realizing above-mentioned purpose; The technical solution of the utility model is: the belt sheave structure of band silicone oil vibration damper, comprise bent axle and silicone oil vibration damper, and an end of bent axle is equipped with first belt pulley; The other end of bent axle is installed on the motor; End near engine side on the bent axle also is provided with the silicone oil vibration damper, and the shell of said silicone oil vibration damper is processed by cast iron, and the outer rim of silicone oil vibration damper is provided with the belt pulley annular groove.
Said silicone oil vibration damper is installed on the bent axle through bolt.
The beneficial effect of the utility model is:
1. the outer rim of the existing silicone oil vibration damper of the utility model is provided with endless-belt wheel groove, to substitute in existing two belt pulleys that are provided with separately, makes the silicone oil vibration damper not only have the function of vibration damper, also has the function of belt pulley.
2. the utility model is simple in structure, has saved a belt pulley, has also just reduced the entire length of motor, makes to move behind each annex of motor head, and more compact structure has been saved installing space, is convenient to arrange and install.
Description of drawings
Fig. 1 is the structural representation of engine belt pulley in the existing technology.
Fig. 2 is the structural representation of the utility model.
Among the figure: first belt pulley, 1, the second belt pulley 2, bent axle 3, silicone oil vibration damper 4, engine side 5.
Embodiment
Below in conjunction with description of drawings and embodiment the utility model is done further to describe in detail.
Referring to Fig. 2; The belt sheave structure of the band silicone oil vibration damper of the utility model comprises bent axle 3 and silicone oil vibration damper 4, and an end of bent axle 3 is equipped with first belt pulley 1; The other end of bent axle 3 is installed on the motor; End near engine side 5 on the bent axle 3 also is provided with silicone oil vibration damper 4, and the shell of said silicone oil vibration damper 4 is processed by cast iron, and the outer rim of silicone oil vibration damper 4 is provided with the belt pulley annular groove.
Said silicone oil vibration damper 4 is installed on the bent axle 3 through bolt.
One end of bent axle 3 is equipped with first belt pulley 1; The other end of bent axle 3 is installed on the motor; Side near engine side 5 on the bent axle 3 also is provided with silicone oil vibration damper 4; Silicone oil vibration damper 4 can reduce the vibrations of bent axle 3, and is very important for protecting bent axle 3 and each annex to play a part, and especially for six cylinder machines, is absolutely necessary.The shell of silicone oil vibration damper 4 is processed by cast iron; And the outer rim of silicone oil vibration damper 4 is provided with the annular groove of belt pulley, has formed second belt pulley 2, and the outer rim that makes it silicone oil vibration damper 4 is provided with the effect of belt pulley; Reduce the entire length of motor, saved installing space.
Silicone oil vibration damper 4 not only has the function of vibration damper, also has the function of belt pulley, and the double belt sheave structure of making has changed conventional construction; Change silicone oil vibration damper shell into the cast iron structure; Silicone oil vibration damper outer rim is made belt sheave structure, and this structure can satisfy the requirement that two belt pulleys are arranged, simultaneously through calculating; This structure also can satisfy the due function of belt pulley for the not influence of function of silicone oil vibration damper.For the outer rim that makes silicone oil vibration damper 4 has the function of first belt pulley 1, just need make that the external profile diameter of silicone oil vibration damper 4 is identical with the diameter of first belt pulley 1 of replacement, could guarantee that speed ratio is constant.Like this, belt pulley-silicone oil vibration damper structure just can reduce by a belt pulley, moves after can making each annex of motor head, thereby has reduced the whole length of motor, has saved installing space.
Claims (2)
1. be with the belt sheave structure of silicone oil vibration damper; Comprise bent axle (3) and silicone oil vibration damper (4); One end of bent axle (3) is equipped with first belt pulley (1), and the other end of bent axle (3) is installed on the motor, and the end that bent axle (3) is gone up near engine side (5) also is provided with silicone oil vibration damper (4); It is characterized in that: the shell of said silicone oil vibration damper (4) is processed by cast iron, and the outer rim of silicone oil vibration damper (4) is provided with the belt pulley annular groove.
