Detailed description of the invention
Fig. 1 shows the sectional view of the oscillating bearing assembly 1 for steering mechanism's (steering cylinder connecting rod and attachment structure of rocking arm), and it includes a kind of form of implementation according to nut check mechanism of the present utility model.The connecting rod 11 of oscillating bearing assembly 1 uses tapered structure, and welds together the boss 2 with tapered structure and rocker arm assembly 3 is assembled together.Connecting rod 11 end thereon has thread section, and is configured with radial perforation in described end thread section.Nut, preferably hex nut 4 are tightened in this end thread section according to the moment of regulation, thus are fixed together with connecting rod 11, boss 2 and rocker arm assembly 3.Here, for preventing hex nut 4 from getting loose, be designed with special retaining mechanism, in the illustrated embodiment, this nut check mechanism includes clamp ring 7, split pin 6 and latch segment 8.This clamp ring is can be enclosed within the end of described connecting rod 11 in the way of the rotation of described end thread section, wherein, under the locking state of diagram, described split pin passes the first hole in clamp ring and the radial perforation in end thread section and such as by pulling open split pin afterbody, thus is fixed un-rotatably by the described the most described connecting rod of clamp ring 7 11.Being provided with at least one described latch segment 8 between the inner circumferential side of described clamp ring and described hex nut, latch segment is firmly clamped between the inner circumferential side of clamp ring and the corresponding outer circumferential side of hex nut, so that hex nut can not rotate.It addition, be also configured with at least one second hole in clamp ring.Steady pin 5 acts against on latch segment and by latch segment 8 relative to described nut check through the second hole in clamp ring, thus more reliably prevents hex nut 4 from rotating relative to connecting rod 11.Just have been able to prevent well nut relative to link rotatable by the latch segment being clamped between clamp ring and nut, and by additionally arranging the second hole and steady pin, then further ensure that the locking effect of latch segment.
Fig. 2 shows the three-dimensional view of steady pin 5.This steady pin is substantially in cylinder, and it at one end can have the fluting with tool engagement, in order to install.
Fig. 3 shows clamp ring 7, and this clamp ring is ringwise.Certainly, clamp ring may be designed in the shape that other is the most appropriate.The circumferential wall of the clamp ring 7 of diagram is configured with two groups of holes, is respectively for the first hole through split pin with for the second hole through steady pin 5.Described first hole is arranged in pairs along the radial direction of clamp ring, preferably 2 or 4.Second hole is preferably correspondingly distributed on the circumferential wall of clamp ring 7 with the outer peripheral face of hex nut, and the second hole can be such as 6 or more.Clamp ring is it is so structured that close in the end near the first hole or be shown in having, near the end in described first hole, the protuberance radially-inwardly highlighted from inner circumferential side, this protuberance radially inner side edge limited go out an opening engaged with the end thread section of connecting rod 11, the end thread section of connecting rod 11 can engage in the openings.
Fig. 4 shows latch segment 8, and this latch segment is clamped between inner peripheral surface and the hex nut of clamp ring 7, and locks hex nut if desired under the effect of steady pin, to prevent hex nut from rotating relative to connecting rod 11, thus realizes locking purpose.Latch segment 8 preferably has the profile that the outer peripheral face with nut adapts in that side engaged with hex nut, thus realizes more solid and reliable power transmission.It addition, latch segment is arranged symmetrically preferably about connecting rod, being preferably arranged symmetrically two, four or six latch segments around nut, the layout of this symmetry provides the stability of structure.
Fig. 5 shows the oscillating bearing assembly 1 including described nut check mechanism.This can be seen that, clamp ring 7 is enclosed within the end thread section of connecting rod 11, and split pin is through the first hole in clamp ring and the perforation in end thread section, and the afterbody of split pin is pulled open, thus prevents clamp ring relative to link rotatable.It is provided with one or more latch segment between the inner peripheral surface and the outer peripheral face of hex nut of clamp ring.Being provided with steady pin 5 in part second hole of clamp ring, latch segment is held out against by this steady pin with hex nut, thus prevents hex nut from rotating.
Industrial applicibility
Nut check mechanism of the present utility model goes for locking various nut, the such as hex nut on the connecting rod 11 of the oscillating bearing assembly 1 being arranged on the steering mechanism of Work machine for locking.
Operation principle by nut locking device of the present utility model described briefly below.
Nut, preferably hex nut 4 are tightened on the end thread section of connecting rod 11.But, when frequently suffering from vibration or impact, nut may link rotatable relatively, thus get loose.For guaranteeing stability and the reliability of steering mechanism, it is necessary to nut is locked.Being designed with special nut check mechanism for this purpose, this retaining mechanism includes clamp ring 7, split pin 6 and latch segment 8.Clamp ring 7, can be enclosed in the way of rotating in the end thread section of connecting rod 11, is additionally provided with a perforation in this end thread section.Being configured with at least two the first hole for split pin in clamp ring 7, described first hole is arranged along the radial symmetric of clamp ring so that split pin can enter from the first hole of side and stretch out from the first hole of opposite side.In order to prevent clamp ring 7 from rotating relative to connecting rod 11, split pin is run through clamp ring and end thread section from the side of clamp ring 7 via the perforation the first hole and end thread section and stretches out from the opposite side of clamp ring, and in order to fasten, split pin afterbody is bent.Thus, clamp ring can not rotate relative to connecting rod 11.It addition, for locking nut, be provided with latch segment between the inner peripheral surface and nut of clamp ring, this latch segment is clamped between clamp ring and nut, thus prevents nut from relative to link rotatable and having reached locking purpose.
In order to better assure that the locking to nut, clamp ring 7 is provided with one group of second hole, and steady pin 5 is held out against on latch segment through this second hole, thus further by nut check, to avoid the most possible the getting loose of latch segment.
In sum, pass through such scheme, avoiding on-the-spot processing in by nut check mechanism described in the utility model and Work machine, machining accuracy is low, easily produces chip, assembly cleannes are low, the problems such as efficiency of assembling is low, and achieve simple to operate, easy to assembly, precision is high, cleannes advantages of higher.
By specific embodiment, nut check mechanism of the present utility model is described above.It is obvious to the skilled person that without departing from the scope or spirit of the invention, foregoing disclosed embodiment can be made various modifications and variations.This specification and disclosed example thereof should be considered to be only exemplary, and the true scope of the present invention is defined by the appended claims and the equivalents thereof.
