Description
Technical field
The utility model relates to a kind of end axle round nut safty device.
Background technique
Existing fork truck is all provided with wheel-side reduction device conventionally, mainly comprises deceleration steel ring, sun gear, epicyclic reduction gear group and clutch end lid, and the steel ring sleeve that wherein slows down is located on end axle, then utilizes a round nut that deceleration steel ring is lock onto on end axle.As shown in Figure 1,9 ' is deceleration steel ring, and 8 ' is round nut, and 91 ' is locking aperture, and 81 ' is screw hole.For nut can not become flexible because of vibration, cause the unstable of steel ring of slowing down, conventionally all can on nut, offer three adjacent angles and be the screw hole of 20 °, and on deceleration steel ring uniform 6 locking apertures that can coordinate with screw hole, when after slewing circle nut check deceleration steel ring, by fine adjustments, make in these three screw holes one to aim at a locking aperture wherein, and with locking nut, both are locked, limit thereby reach the object that round nut rotates.But, in existing heavy forklift, because the weight of its loading is larger, the horsepower of its motor is also larger, and the vibration causing is also larger, in continuous vibration processes, this locking nut is easy to get loose because of this violent vibration, and this phenomenon also occurs in actual use again and again.In order to change this situation, the applicant seeks a kind of more effective safty device and avoids the generation of this phenomenon.
Model utility content
Therefore, for above-mentioned problem, the utility model proposes a kind of simple in structure, convenient and practical, can prevent the end axle round nut safty device that round nut gets loose.
For achieving the above object, the utility model has adopted following technological scheme: a kind of end axle round nut safty device, it is located on deceleration steel ring, described deceleration steel ring is provided with a counterbore, described counterbore is respectively equipped with first step from top to bottom, second step, described first step is provided with cover plate, on described cover plate, be equipped with a pin, the below that is positioned at cover plate on described pin is provided with Ka Tai, between described Ka Tai and second step, be provided with spring, the position that described counterbore is positioned at below second step is provided with screw thread, lower end and the counterbore of described pin are threaded connection, the length of described pin is less than the degree of depth of counterbore so that sell the top of selling while connection with counterbore threads lower than counterbore upper-end surface.
Further, be provided with can be so that the groove of tightening on the top of described pin.
Further, coordinating between described cover plate and counterbore is interference fit.
By adopting aforementioned techniques scheme, the beneficial effects of the utility model are: compared with the mode of locking to realize insurance with existing locking nut, local terminal axle round nut safty device, utilization pin can be along the flexible mode of counterbore, first pin is connected with counterbore threads, thereby make the submerge internal surface of deceleration steel ring of pin, and then will hold the locking of axle round nut, aim at pin finely tuning the screw hole making on round nut after round nut locking, again by pin and counterbore release, thereby pin is ejected, thereby stop the rotation of round nut, and the diameter of cover plate can be arranged to be greater than the diameter of screw hole, thereby cover plate is pushed down by round nut, thereby prevent that cover plate and counterbore from departing from, thereby anti-shotpin departs from from counterbore, thereby prevent that round nut is loosening, and round nut cannot become flexible and makes cover plate be held down, form the state of a self-locking.The screw hole setting here can change original mode, is arranged to a plurality of modes that distribute along even circumferential, while being more conducive to lock with the coordinating of pin.
Brief description of the drawings
Fig. 1 is strand schematic diagram that connects of existing deceleration steel ring and round nut;
Fig. 2 is the structural representation of deceleration steel ring and round nut;
Fig. 3 is structural representation of the present utility model.
Embodiment
Now with embodiment, the utility model is further illustrated by reference to the accompanying drawings.
With reference to figure 2, Fig. 3, the present embodiment provides a kind of end axle round nut safty device, it is located on deceleration steel ring 9, the mode that steel ring 9 utilizes round nut 8 to lock is sheathed on end axle, on the circumference of described round nut 8, be provided with evenly distributedly a plurality of screw holes 81, described deceleration steel ring 9 is provided with a counterbore 1, described counterbore 1 is respectively equipped with first step 11 from top to bottom, second step 12, described first step 11 is provided with cover plate 2, on described cover plate 2, be equipped with a pin 3, the below that is positioned at cover plate 2 on described pin 3 is provided with card platform 31, between described card platform 31 and second step 12, be provided with spring 4, described counterbore 1 is positioned at the position 12a of second step below 12 and is provided with screw thread, the lower end of described pin 3 and counterbore 1 are threaded connection, the length of described pin 3 is less than the degree of depth of counterbore 1 so that pin 3 is sold 3 top while being threaded with counterbore 1 lower than counterbore 1 upper-end surface.The top of described pin 3 is provided with can be so that the groove 32 of tightening.Coordinating between described cover plate 2 and counterbore 1 is interference fit.
Compared with the mode of locking to realize insurance with existing locking nut, local terminal axle round nut safty device, utilization pin can be along the flexible mode of counterbore, first pin is connected with counterbore threads, thereby make the submerge internal surface of deceleration steel ring of pin, and then will hold the locking of axle round nut, aim at pin finely tuning the screw hole making on round nut after round nut locking, again by pin and counterbore release, thereby pin is ejected, thereby stop the rotation of round nut, and the diameter of cover plate can be arranged to be greater than the diameter of screw hole, thereby cover plate is pushed down by round nut, thereby prevent that cover plate and counterbore from departing from, thereby anti-shotpin departs from from counterbore, thereby prevent that round nut is loosening, and round nut cannot become flexible and makes cover plate be held down, form the state of a self-locking.The screw hole setting here can change original mode, is arranged to a plurality of modes that distribute along even circumferential, while being more conducive to lock with the coordinating of pin.
Although specifically show and introduced the utility model in conjunction with preferred embodiment; but those skilled in the art should be understood that; not departing from the spirit and scope of the present utility model that appended claims limits; can make a variety of changes the utility model in the form and details, be protection domain of the present utility model.
