According to technological scheme provided by the invention: motor car engine location one-way belt sheave, comprise belt wheel, unidirectional needle bearing and sleeve, described sleeve is arranged in the belt wheel, and sleeve first end is used for connecting generator, and described unidirectional needle bearing is installed between sleeve and the belt wheel; It is characterized in that: second end of described belt wheel and sleeve is by Sealing shield ring, cover plate and seal ring sealing, described cover plate is installed in the endoporus of belt wheel second end, described seal ring is arranged between cover plate inner hole wall and the sleeve outer wall, described Sealing shield ring is arranged on cover plate and the seal ring outside, and Sealing shield ring is installed in the endoporus of belt wheel second end.
As a further improvement on the present invention, described unidirectional needle bearing two ends are respectively arranged with first positioning bearing and second positioning bearing.Described belt wheel inwall is provided with the first step for location first positioning bearing, and described sleeve outer wall is provided with the second step for location second positioning bearing.
As a further improvement on the present invention, be provided with the spline that makes things convenient for its installation in the endoporus of described sleeve second end.Belt grooves on the described belt wheel is arranged on belt wheel first end.Described belt grooves is the v belt groove.Described first positioning bearing and second positioning bearing adopt the 6805-2RS bearing.
The present invention compared with prior art, advantage is:Structure of the present invention is ingenious rationally, utilizes the eccentric self-locking of unidirectional needle bearing to realize that single direction rotates, and has reduced the influence of generator inertial mass to accessory system on the one hand, promotes and issues rotating speed of motor rapidly; Reduce tension force and shake and the noise of belt on the other hand, promoted the working life of belt; But also reduced the rate of skidding of train, and having reduced the discharge amount of oil consumption and expense gas, energy-saving effect is remarkable, is particularly suitable for being applied on the limousine.In addition, the present invention can select belt and tension device cheaply for use, reduces the gear quantity in the train, reduces the speed value of generator.
Description of drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is that A-A among Fig. 1 is to view.
Embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As shown in the figure, the location of the motor car engine among embodiment one-way belt sheave mainly is made up of component such as Sealing shield ring 1, cover plate 2, seal ring 3, belt wheel 4, unidirectional needle bearing 5, sleeve 6, first positioning bearing 7 and second positioning bearings 10.
As shown in Figure 1, described sleeve 6 is arranged in the belt wheel 4, and sleeve 6 first ends are used for connecting generator, and described unidirectional needle bearing 5 is installed between sleeve 6 and the belt wheel 4; Second end of described belt wheel 4 and sleeve 6 enters to prevent dust, liquid by Sealing shield ring 1, cover plate 2 and seal ring 3 sealings.Described cover plate 2 is installed in the endoporus of belt wheel 4 second ends, and described seal ring 3 is arranged between cover plate 2 inner hole walls and sleeve 6 outer walls, and described Sealing shield ring 1 is arranged on cover plate 2 and seal ring 3 outsides, and Sealing shield ring 1 is installed in the endoporus of belt wheel 4 second ends.
As shown in Figure 1, because belt pulley 4 has certain axial impact force in the real-world operation process, make belt wheel 4 produce axial motions, so the present invention is provided with first positioning bearing 7 and second positioning bearing 10 respectively at described unidirectional needle bearing 5 two ends, is used for belt pulley 4 is carried out axially locating.Described belt wheel 4 inwalls are provided with the first step 9 for location first positioning bearing 7, and described sleeve 6 outer walls are provided with the second step 11 for location second positioning bearing 10.
As shown in Figure 1, be provided with spline 12 in the endoporus of described sleeve 6 second ends, to make things convenient for the installation of sleeve 6.Belt grooves 8 on the described belt wheel 4 is arranged on belt wheel 4 first ends, and belt grooves 8 preferably is set to v belt groove 8.
