Description
Technical field
The utility model relates to fastening connection piece field in machining, particularly relates to a kind of loose-resitant belt tooth stud.
Background technique
Stud adopts two ends screw thread to realize the fastening piece connected, and be convenient to dismounting, can reuse, major function is firm and power transmission.What wherein have a kind of employing be connected with other component for body is interference stud, and the two ends screw thread of interference stud, one end is the interference thread being screwed into body end, and another end is the regular screw threads be connected with other component.The interference thread that interference stud is screwed into body end is different with the material of stud and select different effective diameter of thread magnitude of interference by body, relative fixing to ensure that stud in use keeps with body, prevents stud from loosening.The required precision of this kind of interference thread is very high has higher difficulty of processing, and productivity is lower, easily causes waste product in course of working.
Summary of the invention
The object of this model utility is to provide a kind of loose-resitant belt tooth stud, simultaneously so that the stud of processing, the main structure of this stud comprises: band tooth stud, be screwed into body end, stud one end regular screw threads, external spline teeth, stud the other end regular screw threads, fan tooth, inner spline gear, fan tooth locking ring, in common stud stage casing, an external spline teeth is set, fan tooth locking ring is provided with outside external spline teeth ring, fan tooth locking ring inwall is provided with inner spline gear, inner spline gear is established in fan tooth locking ring outer shroud both sides, external spline teeth also engages with the inner spline gear of fan tooth locking ring, screw thread stud being screwed into body end is set to regular screw threads, the stud the other end is also set to regular screw threads, fan tooth locking ring is embedded body, utilize the fan tooth on fan tooth locking ring relative with body fixing, reach the effectively locking of stud.
Adopt the beneficial effect of the technical program: compared with prior art, structure is simple, easy to implement, effect is safe and reliable, and screw thread adopts regular screw threads, reduces the difficulty of processing of screw thread, improves manufacturing efficiency.Effectively reduce the reject rate of production, cost-saving, increase economic efficiency, various machinery industry can be applied to by popularity, have good economic benefit and social benefit.
