Description
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.
Description of drawings
Now in conjunction with the accompanying drawings the utility model is described further:
Fig. 1 is the mounting structure synoptic diagram of existing rotary encoder;
Fig. 2 is a main axis rotation state measurement structural scheme of mechanism described in the utility model.
As shown in Figure 2, main axis rotation state measurement described in the utility model mechanism includes hyperchannel swivel adapter head 11, rotary main shaft 12, main shaft terminal pad 13, screw 14, shaft coupling 15, fixed head 16, rotary encoder 17, screw 18.
Embodiment
Embodiment 1, and main axis rotation state measurement described in the utility model mechanism mainly includes hyperchannel swivel adapter head 11, rotary main shaft 12, main shaft terminal pad 13, shaft coupling 15 and fixed head 16, rotary encoder 17.
Described main axis rotation state measurement mechanism, its shaft coupling 15 is with rotary encoder 17 and rotary main shaft 12 connecting as one structure with one heart.
The upper and lower side of described shaft coupling 15 has designed through hole respectively, and the mandrel of rotary encoder 17 can and interconnect fixing from its lower end through hole insertion.
Between described rotary main shaft 12 and shaft coupling 15, dispose a main shaft terminal pad 13.
Rotary main shaft 12 is connected with the interior axle of hyperchannel swivel adapter head 11, and main shaft terminal pad 13 links together by screw 14 and rotary main shaft 12.
The design of the lower surface centre of described main shaft terminal pad 13 has a columnar projections, this columnar projections can insert in the through hole of shaft coupling 15 lower ends and interconnect fixing.
Described rotary encoder 17 links together by screw 18 and fixed head 16, and fixed head 16 is connected with the rocker body of rotary main shaft 12 again.
As mentioned above, described main axis rotation state measurement mechanism is applied in tire dynamic and balance and the uniformity test measurement for the speed of mainshaft and angular displacement after fixedly connected.Metering system and step are particularly:
On rotatable main shaft, tire before test by clamping on main shaft, can carry out high speed rotating during test;
Rotary main shaft is connected with axle in the hyperchannel swivel adapter head;
Constitute main axis rotation state measurement mechanism by rotary main shaft, main shaft terminal pad, shaft coupling and rotary encoder etc.;
The main shaft terminal pad links together rotary main shaft and rotary encoder by shaft coupling.
The rotary state of rotary main shaft synchronously passes to rotary encoder.
The speed of mainshaft, angular displacement and force sensor measuring numerical value is corresponding one by one, draw the unbalance amount of tire curve of cyclical fluctuations, resolve through a series of again, draw the tire unbanlence numerical quantity.
