Abstract
The utility model relates to the field of metal rolling, in particular to a thread off prevention roller retainer ring, and the utility model provides a retainer ring which is provided with a bolt and has the withdrawing prevention function aiming at the shortcomings in the prior art that a bolt of a roller retainer ring is easy to release during vibration. The thread off prevention roller comprises a ring body and a connecting bolt, wherein the ring body comprises two semi-circular rings which are connected, wherein one connecting end of the ring body is a hinged, the other end is connected through a connecting bolt which laterally penetrates through the composition planes of the two semi circles, the corresponding portion of two ends of a threaded hole is further provided with a bolt mounting groove, a spring washer is further arranged between the connecting bolt and the ring body, a pin hole is further arranged on the ring body, the pin hole is arranged on the rear portion of the head portion of the connecting bolt, a bolt retaining pin is arranged in the pin hole, and the bolt retaining pin is pressed on the top end of the connecting bolt. A retaining pin is increased on the rear portion of the connecting bolt in the retainer ring, and the thread off prevention roller retainer ring can effectively prevent the connecting bolt from being released, and further reinforces the fixation of the retainer ring on a rolling mill.
Description
Technical field
The utility model relates to metal rolled field, especially a kind of anticreep roll snap ring.
Background technology
The roll snap ring is one of main fastenings of roll and bearing block, bearing block and roll fixedly be the key factor that milling train stable operation guarantees equipment operation rate.Snap ring of the prior art is by two hinged annulus that semicircular ring is formed by connecting by connecting bolt of an end.During work, snap ring is loaded in the annular groove in the roll chock retaining ring outside, in order to the relative position of fixed bearing block and roll, prevents that bearing block from moving outward.Yet because roll drenches and impacts under the heavily loaded environment and work at high temperature, many dirt, water usually, vibrations are frequent, and the connecting bolt that is used for fixing snap ring still gets loose in vibrations easily, thereby cause milling train to be shut down, and then influence operating rate.
The utility model content
The purpose of this utility model is: the drawback at the bolt of roll snap ring in the prior art easily gets loose in vibrations provides a kind of snap ring that has the bolt stopping function.
For solving the problems of the technologies described above, technical solutions of the utility model are to realize like this, a kind of anticreep roll snap ring, form by ring body and connecting bolt, described ring body is connected and composed by two semicircular ring, an one link is hinged, the other end connects by the connecting bolt that crosses two semicircular ring composition surfaces, counterpart at the screw two ends also has the bolt mounting groove, also be provided with spring washer between described connecting bolt and ring body, it is characterized in that: also be provided with pin-and-hole on described ring body, described pin-and-hole is positioned at the rear of connecting bolt head, be provided with the bolt retaining pin in the pin-and-hole, described bolt retaining pin is butted on the connecting bolt top.
Described bolt retaining pin is a spring catch.
The beneficial effects of the utility model: the connecting bolt rear increases retaining pin in snap ring, can effectively avoid getting loose of connecting bolt, further consolidates snap ring fixing on milling train.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the utility model bolt link partial sectional view.
The specific embodiment
Referring to shown in Figure 1, anticreep roll snap ring described in the utility model, a kind of anticreep roll snap ring is made up of ring body 1 and connecting bolt 2.Wherein, ring body 1 is connected and composed by two semicircular ring, and an one link is hinged, and the other end connects by the connecting bolt 2 that crosses two semicircular ring composition surfaces 11, counterpart at the screw two ends also has bolt mounting groove 12, also is provided with spring washer 13 between connecting bolt 2 and ring body.
At work, the snap ring of releasing orientation is loaded in the annular groove in the roll chock retaining ring outside after, screw connecting bolt 2, snap ring is fixed in the groove.
Also be provided with pin-and-hole 14 on ring body 1, pin-and-hole 14 is positioned at the rear of connecting bolt 2 heads, is provided with bolt retaining pin 3 in the pin-and-hole 14, and bolt retaining pin 3 is a spring catch, and is butted on connecting bolt 2 tops, referring to Fig. 2.Like this, in the working environment of vibrations, even connecting bolt 2 has loosening sign, also since the rear also kept off bolt retaining pin 3 and can not get loose, thereby guarantee stable, reliable, the safety of milling train work.
