Description
Technical field
The present invention relates to universal joint, also relate in addition and prevent that universal joint from the device of big-eared phenomenon occurring.
Background technique
Big-eared phenomenon of so-called universal joint, now take the cardan universal joint shown in Fig. 1 and illustrates as example.As shown in Figure 1, because cardan universal joint its two ends before not being installed on relevant device are unfixing, under Action of Gravity Field, universal joint can be take cross bag center and be naturally drooped as rotating center, until upper flange jaw contacts with lower flange jaw, so far, these two flange jaws cannot vert again.Above-mentioned phenomenon expends for a long time and aims at manpower in the time of can causing universal joint is installed, and has increased installation difficulty, and also more difficult at dismounting universal joint.To this, be necessary to design a kind of anti-big-eared head unit and avoid universal joint to manufacture to the transportation, big-eared the phenomenon of storing process generation that are installed to user's field apparatus from manufacturing firm.
Summary of the invention
The present invention aims to provide a kind of universal joint of anti-big-eared head.
For this reason, the universal joint of this anti-big-eared head comprises driving link and the driven member through universal connection, between described driving link and driven member, be connected with at least one anti-big-eared head unit, described anti-big-eared head unit comprises a controlling device and the connector element that is connected to controlling device two ends, and these two connector elements are connected with driven member with driving link respectively.Term in the application " driving link " and " driven member " are only for convenience of description and the appellation adopting that only expression has two members of universal connecting relation, and does not relate between these two members whether having drive connection.In actual use occasion, " driving link " and " driven member " both may have drive connection (such as two flange jaws in background technique), may be only also to realize inter-agency connection.Wherein, term " universal connection " had both comprised Cardon universal joint, also comprised Rzeppa type, twin, curved grooved type, projection formula, three pin-type etc.After being connected with driven member with driving link by connector element respectively in above-mentioned controlling device, the rotary freedom between driving link and driven member is limited, play thus the object of anti-big-eared head.Because controlling device has regulatory function, after connecting, anti-big-eared head unit can suitably regulate the length, angle of this controlling device etc., to the relative position between driving link and driven member is regulated.Between driving link and driven member, be preferably connected with a plurality of anti-big-eared head units, these anti-big-eared head units are uniform along the periphery of universal joint.In this case, by regulating each controlling device can make each anti-big-eared head unit put on pulling force certain on driving link and driven member, thereby effectively driving link and driven member are carried out to hi-Fix.
Concrete structure as controlling device, this controlling device comprises an adjusting nut and the upper thread being threaded with this adjusting nut respectively and lower thread, the Hand of spiral of the screw thread on described upper thread is contrary with the Hand of spiral of screw thread on lower thread, and described connector element is connected on thread and lower thread.After connecting, anti-big-eared head unit rotates adjusting nut, because the Hand of spiral of the screw thread on upper thread is contrary with the Hand of spiral of screw thread on lower thread, therefore upper thread and lower thread outwards extend synchronizing moving difference, thereby realize the quick adjustment of length.Certainly, controlling device also can adopt other structure, such as controlling device being designed to by bolted two connecting plates, and open respectively slotted hole on these two connecting plates, unclamp the relative position that can regulate arbitrarily these two connecting plates after bolt, regulate after suitable and by bolt, these two connecting plates are fixed again.Or, also controlling device can be designed to by the structure of two pivoted arms of stud connection, these two pivoted arms both can rotate mutually, also can be fixed.
For convenience of connecting, the upper end of described upper thread is provided with jaw, and the lower end of described lower thread is provided with lower jaw, and described upper jaw and lower jaw are respectively and hinged by bearing pin between each self-corresponding connector element.In addition, the application advises that described connector element all adopts lifting bolt, and hinged by bearing pin between the suspension ring of each lifting bolt and controlling device, the double-screw bolt of each lifting bolt is connected with the screw on driving link or driven member.Like this, just require difference processing screw hole on driving link and driven member.
According to the universal joint of anti-big-eared above, the present invention obviously also provides a kind of anti-big-eared head unit, and this device comprises a controlling device and the connector element that is connected to controlling device two ends.Concrete, described controlling device comprises an adjusting nut and the upper thread being threaded with this adjusting nut respectively and lower thread, the Hand of spiral of the screw thread on described upper thread is contrary with the Hand of spiral of screw thread on lower thread, and described connector element is connected on thread and lower thread.The upper end of described upper thread is also provided with jaw, and the lower end of described lower thread is also provided with lower jaw, and described upper jaw and lower jaw are hinged by bearing pin respectively and between each self-corresponding connector element.In addition, described connector element all adopts lifting bolt, hinged by bearing pin between the suspension ring of each lifting bolt and controlling device.
Below in conjunction with the drawings and specific embodiments, the present invention is described further.The aspect that the application is additional and advantage in the following description part provide, and part will become obviously from the following description, or recognize by the application's practice.
