The utility model relates to a measuring mechanism for a main shaft rotary state, and is designed with an integrated rotary encoder structure which is concentrically connected with a rotary main shaft, basically eliminating the problem that the measurement of main shaft speed is non-synchronous with the measurement of angle displacement. The measuring mechanism for a main shaft rotary state mainly comprises a rotary encoder and a coupling which is connected to the main shaft and the rotary encoder, and by the coupling, the rotary encoder is concentrically connected with the rotary main shaft into an integrated structure.

Description

Main axis rotation state measurement mechanism

Technical field

The utility model relates to a kind of novel main axis rotation state measurement mechanism, specifically to the improvement of the rotary encoder fixed sturcture of wheel balance and uniformity test device.

Background technology

Along with increasing substantially of domestic all kinds of sales of automobile, requirements at the higher level have been proposed for the safe handling and the relevant art standard of tire.Balance and homogeneity are to influence the principal element that tire safety uses.In existing wheel balance and the uniformity test process, tire on rotary main shaft, is utilized rotary encoder to measure the variation of the speed of mainshaft and angular displacement by clamping, thereby the mensuration numerical value of adhesion sensor sensing power is finished the measuring and calculating of unbalance amount of tire.

In existing wheel balance and the uniformity test device, adopt structure as shown in Figure 1 usually, dispose a synchronous belt wheel 2 in the lower end of rotary main shaft 1, this synchronous pulley 2 adopts keyway type to be connected with rotary main shaft 1, and both can be rotated synchronously; On the same surface level in synchronous pulley 2 places, be provided with between another synchronous pulley 3, two synchronous pulleys of same size with being with 3 to connect transmissions synchronously.Owing to 3 certain extensibility is arranged synchronously, main shaft 1 vibration is bigger in the measuring process of unbalance amount of tire in addition, thereby the rotary state of the rotation of main shaft 1 and rotary encoder 5 is impossible fully synchronous, thereby the measured value of the speed of mainshaft and angular displacement is inaccurate, also just can not correct drawing go out the curve of cyclical fluctuations of unbalance amount of tire, cause the test findings deviation bigger.

Summary of the invention

Main axis rotation state measurement described in the utility model mechanism is intended to address the above problem with not enough and design has and the concentric integrated rotary encoder structure that is connected of rotary main shaft, can eliminate the speed of mainshaft and the nonsynchronous problem of angle displacement measurement basically.

Described main axis rotation state measurement mechanism, the shaft coupling that mainly includes rotary encoder and connect main shaft and rotary encoder.

By described shaft coupling, with concentric the connecting as one structure of rotary encoder and rotary main shaft.

The upper and lower side of described shaft coupling has designed through hole respectively, and the mandrel of rotary encoder can insert from its lower end through hole, and by being spirally connected or the riveted joint mode interconnects both fixing.

The position also disposes a main shaft terminal pad between described rotary main shaft and shaft coupling.

The design of the lower surface centre of described main shaft terminal pad has a columnar projections, this columnar projections can insert in the through hole of shaft coupling lower end and interconnect fixing.

Described main shaft terminal pad is by being spirally connected or riveted joint mode and rotary main shaft link together.

Described rotary encoder is by being spirally connected or the riveted joint mode is fixedlyed connected with the rocker body.

As mentioned above, described main axis rotation state measurement mechanism has the following advantages:

1, main shaft can be connected with one heart with rotary encoder by shaft coupling, solve the deviation of dividing body structure that test figure is caused because of rotary encoder;

2, rotary encoder and main shaft closely link together and both high level of synchronization, can guarantee the accuracy of the speed of mainshaft and angle displacement measurement;

3, adopt described coupler structure,,, help further improving measurement accuracy so can bear certain axis installation deviation because of its elastic properties of materials is bigger.
