Problems solved by technology
like figure 1 As shown, since the two ends of the cross shaft universal joint are not fixed before it is installed on the relevant equipment, under the action of gravity, the universal joint will naturally sag with the center of the cross package as the center of rotation until the fork of the upper flange and the The lower flange yokes are in contact, so far, the two flange yokes can no longer tilt
The above phenomena will take a long time and manpower to align when installing the universal joint, which increases the difficulty of installation, and it is also difficult to disassemble the universal joint

Embodiment Construction
[0016] Such as Figure 1 to Figure 5 As shown, there are four screw holes evenly distributed on the outer circumference of the flange of the active part 1 (upper flange yoke), and there are also four screw holes on the outer circumference of the flange of the follower 3 (lower flange yoke). Four screw holes are evenly distributed, and a lifting eye screw 505 is installed on each of the above screw holes, and each lifting ring screw 505 installed on the active part 1 is connected with the corresponding lifting ring screw 505 installed on the driven part 3. An adjustment device, each adjustment device includes an adjustment nut 501 and an upper threaded pull rod 502A and a lower threaded pull rod 502B that are threadedly connected with the adjustment nut 501 respectively. The helical direction of the thread on the top is opposite. The upper end of the upper threaded rod 502A is provided with an upper fork 503A, and the lower end of the lower threaded rod 502B is provided with a ...

The invention discloses a universal joint of an anti-drooping head. The universal joint comprises a driving part and a driven part which are universally connected, at least one anti-drooping head device is connected between the driving part and the driven part, the anti-drooping head device comprises an adjusting device and connecting members which are respectively connected to two ends of the adjusting device, and the two connecting members are respectively connected with the driving part and the driven part. After the adjusting device is connected with the driving part and the driven part through the connecting members respectively, the rotational degree of freedom between the driving part and the driven part is limited, so that the aims of the anti-drooping head are fulfilled. The adjusting device has a length adjusting function, and the adjusting device can be properly adjusted after the anti-drooping head device is connected, so that the anti-drooping head device pulls the driving part and the driven part.
Description
technical field [0001] The present invention relates to a universal joint, and also relates to a device for preventing the universal joint from drooping. Background technique [0002] The so-called drooping phenomenon of the universal joint is now figure 1 Take the cross shaft universal joint shown as an example for illustration. Such as figure 1 As shown, since the two ends of the cross shaft universal joint are not fixed before it is installed on the relevant equipment, under the action of gravity, the universal joint will naturally sag with the center of the cross package as the center of rotation until the fork of the upper flange and the The lower flange prongs are in contact, so far, these two flange prongs can no longer tilt. The above-mentioned phenomenon will lead to a long time-consuming and labor-intensive alignment when installing the universal joint, which increases the difficulty of installation, and it is also difficult to disassemble the universal joint. ...
