Abstract
The invention discloses a connecting structure of a motor for a speed measurement device and an electric vehicle. The connecting structure comprises a motor main shaft (1) and a small converting shaft (3), wherein a central hole (2) is arranged in the end surface of the non-shaft extending end of the motor main shaft (1), a chamfer is arranged at one end of the small converting shaft (3), a limiting ring (4) coaxial to the small converting shaft is arranged on the small converting shaft (3), the chamfer end of the small converting shaft (3) is inserted and connected into the central hole (2), the non-chamfer end of the small converting shaft (3) is connected with the input end of a photoelectric encoder (5), and the central hole (2) is also directly connected with the input end of the photoelectric encoder (5). The connecting structure has the advantages that the encoder can be changed conveniently, the replacement is easy, and the consuming time is short.
Description
Technical field
The present invention relates to a kind of syndeton of speed measuring device, be specifically related to the syndeton of a kind of speed measuring device and motor of electric motor car.
Background technology
Motor of electric motor car main shaft speed measuring device is a kind of device that converts angular displacement or straight-line displacement to electric wire size.At present, speed measuring device adopts magnetism encoder and photoelectric encoder mostly.Wherein photoelectric encoder is a kind of angle (angular speed) checkout gear, and it will input to the angular displacement of axle, utilize photoelectricity transformation principle to change into corresponding electric pulse or digital quantity, has that volume is little, precision is high, advantages such as reliable operation and interface digitlization.Magnetism encoder is a kind of angle and displacement measuring device; Its principle is to adopt magnetic resistance or Hall element that the displacement of the magnetic material of variation is measured; The variation of magnetic material angle or displacement can cause the variation of certain resistance or voltage; Amplify changing through amplifying circuit, handle back output pulse signal or analog signals, reach the purpose of measurement through single-chip microcomputer.Magnetism encoder has anti-vibration, anticorrosive, antipollution, anti-interference and characteristics that operating temperature range is big.
Because principle, structure and the advantage of photoelectric encoder and magnetism encoder have nothing in common with each other, and are adapted at using on the various conditions.At present, all be that photoelectric encoder or magnetism encoder directly are connected with electric machine main shaft, on promptly a kind of electric machine main shaft a kind of encoder can only be installed, just change encoder and must change electric machine main shaft simultaneously, its working procedure is complicated, length consuming time.
Summary of the invention
The object of the invention promptly is to overcome the deficiency of prior art, and a kind of syndeton of speed measuring device and motor of electric motor car of conveniently replaced encoder is provided.
The object of the invention is realized through following technical scheme:
The syndeton of speed measuring device and motor of electric motor car; It comprises electric machine main shaft; The end face of the non-shaft stretching end of electric machine main shaft is provided with centre bore, and it also comprises the little axle of conversion, and an end of changing little axle is provided with chamfering; Change little axle and be provided with and change the coaxial spacing ring of little axle, the chamfered end of changing little is plugged in the centre bore.
The non-chamfered end of changing little axle is connected with the input of photoelectric encoder.
Centre bore directly is connected with the input of magnetism encoder.
The invention has the advantages that: in the time of using magnetism encoder, directly magnetism encoder is connected with centre bore on the electric machine main shaft, in the time of using photoelectric encoder; Only need take off magnetism encoder; Install the little axle of conversion then, again photoelectric encoder is installed in the little axle of conversion and upward gets final product, removed the trouble of changing electric machine main shaft from; Construction is simple, weak point consuming time.

The structural representation that Fig. 1 is connected with photoelectric encoder for the present invention
The structural representation that Fig. 2 is connected with magnetism encoder for the present invention
Among the figure, 1-electric machine main shaft, 2-centre bore, the little axle of 3-conversion, 4-spacing ring, 5-photoelectric encoder, 6-magnetism encoder.
Embodiment
Below in conjunction with accompanying drawing the present invention is described further, protection scope of the present invention is not limited to the following stated.
As shown in Figure 1; The syndeton of speed measuring device and motor of electric motor car, it comprises electric machine main shaft 1, the end face of the non-shaft stretching end of electric machine main shaft 1 is provided with centre bore 2; It also comprises the little axle 3 of conversion; An end of changing little axle 3 is provided with chamfering, changes little axle 3 and is provided with and changes the coaxial spacing ring 4 of little axle, and the chamfered end of changing little 3 is plugged in the centre bore 2.The non-chamfered end of changing little axle 3 is connected with the input of photoelectric encoder 5.
As shown in Figure 2, in the time of using magnetism encoder 6, only need pull down photoelectric encoder 5 and the little axle 3 of conversion, the input of magnetism encoder 6 is connected with centre bore 2 gets final product then.
