Abstract
The utility model discloses a mounting device for a rotary encoder of an automobile chassis dynamometer, which is characterized by comprising a body. A first through hole, second through holes and a third through hole are arranged on the body, the first through hole is matched with a boss of the encoder, the second through holes evenly distributed around the first through hole are matched with threaded holes on the encoder, and the third through hole is used for a bolt to pass through. The mounting device is simple in structure and convenient in use, the first through hole and the second through holes are respectively matched with the encoder, the third through holes are matched with a nut through a supporting bolt prior to being fixed to an equipment frame, and thereby a shell of the encoder can be prevented from rotating along a rotary shaft in rotation, radial play and axial play of an encoder shaft caused by mounting different shafts can be eliminated effectively, the encoder is not easy to damage and test precision is guaranteed. Therefore, the mounting device is suitable for popularization and application.
Description
Technical field
The utility model relates to a kind of scrambler erecting device, specifically is meant a kind of road simulation dynamometer rotary encoder erecting device.
Background technology
Along with the development of society, the raising of people's living standard, automobile day by day becomes the product that ordinary people can be consumed.The existing mounting means that is used for the rotary encoder of testing automobile dynamometer roller rotating speed normally directly or indirectly is fixed in device framework with scrambler at present, adopt flexible clutch that scrambler is connected with the cylinder output shaft, thereby scrambler input shaft and cylinder output shaft are rotated synchronously.Because the flexible scope restriction of shaft coupling, higher to the scrambler input shaft with the coaxial accuracy requirement of the installation of cylinder output shaft, under the situation of cylinder high speed rotating, can not effectively avoid damaging scrambler easily and influencing measuring accuracy because scrambler shaft run-out and the axial runout that disalignment causes is installed.
The utility model content
The purpose of this utility model is to overcome the rotary encoder that will be used for testing automobile dynamometer roller rotating speed at present and directly or indirectly is fixed in device framework, when the cylinder high speed rotating, can not effectively avoid because scrambler shaft run-out and the axial runout that disalignment causes is installed, thereby the defective of damaging scrambler easily and influencing measuring accuracy, provide a kind of and can effectively eliminate because scrambler shaft run-out and the axial runout that disalignment causes is installed, thus the road simulation dynamometer rotary encoder erecting device of not fragile scrambler and assurance measuring accuracy.
The utility model is achieved through the following technical solutions: road simulation dynamometer rotary encoder erecting device, mainly form by main body; At through hole one that the boss that is provided with on this main body with scrambler is complementary, be complementary and be evenly distributed on through hole two around the through hole one and the through hole three that is used to pass set bolt with threaded hole on the scrambler.
Further, described through hole three is a mounting hole.
In order to satisfy the demand, through hole to be set on described main body to hold one by one and be provided with the fillet that is complementary with the scrambler profile.
In order better to realize through hole 31 ends being set the utility model also being provided with chamfering, and form two symmetrical inclined-planes and a bottom surface on described main body.
In order to better meet needs, the height on described inclined-plane is half of body height.
Simultaneously, the length of described bottom surface is half of body width.
In order to ensure effect, described main body adopts steel plate to be made.
The utility model compared with prior art has the following advantages and beneficial effect:
(1) the utility model is not only simple in structure, and easy to use.
(2) through hole one of the present utility model and through hole two cooperate with scrambler respectively, three of through holes are fixed on the device framework after cooperating by supporting bolts and nuts, the shell that prevents scrambler rotates with the rotation of rotation axis, effectively eliminated because scrambler shaft run-out and the axial runout that disalignment causes is installed, thereby not fragile scrambler, and guaranteed the precision of testing.
(3) the utility model is provided with through hole and holds one by one and be provided with the fillet that is complementary with the scrambler profile on described main body, and the profile of main body and scrambler is mated more, and integral body coordinates more, attractive in appearance.
(4) through hole three of the present utility model is made as mounting hole, can adjust by supporting nut and the position of bolt on device framework, and main body and device framework better are fixed together, thus better regular coding device.
Description of drawings
Fig. 1 is an one-piece construction synoptic diagram of the present utility model.
The one-piece construction synoptic diagram that Fig. 2 is connected with device framework, scrambler and rotation axis for the utility model.
Embodiment
Below in conjunction with embodiment the utility model is described in further detail, but embodiment of the present utility model is not limited thereto.
Embodiment
As shown in Figure 1, 2, the utility model mainly is made up of main body 1, and this main body 1 adopts steel plate to be made.For this main body 1 is installed on the boss of scrambler 8, on this main body 1, be provided with the through hole 1 that the boss with scrambler 8 is complementary.For main body 1 and scrambler 8 are fixed together, be provided with on this main body 1 with scrambler 8 on threaded hole through hole 23 mutually, and through hole 23 be evenly distributed on through hole 1 around.For main body 1 is connected with device framework 11, on this main body 1, also be provided with the through hole 34 that is used to pass set bolt 12.In order better to realize the utility model, this through hole 34 is made as mounting hole.
For better and scrambler 8 are complementary, through hole one 2 one ends are set on described main body 1 are provided with the fillet 5 that is complementary with scrambler 8 profiles.Simultaneously, through hole 341 ends are set on described main body 1 also are provided with chamfering, and form two symmetrical inclined-planes 6 and a bottom surface 7.The height on this inclined-plane 6 is half of main body 1 height, and the length of bottom surface 7 then is half of main body 1 width.
During installation, the boss of scrambler 8 is passed the through hole 1 of main body 1, and pass threaded hole on through hole 23 and the scrambler 8, scrambler 8 and main body 1 are fixed together by screw 14.Simultaneously, with scrambler 8 the axle be connected with rotation axis 9 by screw 10, main body 1 is then passed through hole 34 by set bolt 12 and is connected with device framework 11.Simultaneously, set bolt 12 is fixed together with device framework 11 by the nut 13 that matches, and deviates from device framework 11 to prevent set bolt 12.
As mentioned above, just can realize the utility model preferably.
