Abstract
The utility model relates to a novel multifunctional nut, which belongs to the field of machinery parts. The novel multifunctional nut comprises a nut body (1) and a gasket (3), wherein a rabbet (2) is arranged at the bearing surface end of the nut body (1), and the gasket (3) is attached to the rabbet (2) of the nut body (1); the gasket (3) is firmly stuck with the rabbet surface of the rabbet (2) of the nut body (1) to form a whole; and the gasket (3) is made of synthetic rubber, therefore, the multifunctional nut is durable and wear-resistant, can be repeatedly assembled and dissembled and reused. The provided novel multifunctional nut has the pretensioning, anti-loosening and sealing functions and is used for eliminating the axial clearance; and the shaft end is sealed when the bearing is pretensioned, and the clearance caused by the worn part after long-term running is eliminated, therefore, the intended functions and the service life of the equipment are prolonged.
Description
Technical field
The utility model belongs to the mechanical parts field, relates to a kind of Multifunction nut.
Background technique
Nut claims nut again, is screwed in the part that is used for playing the role of fastening with bolt or screw rod, and a kind of original paper that all manufacture the necessary usefulness of machinery is divided into numerous species such as lock nut.As: at a lot of industrial fields, the rotating speed of axle is more and more higher, and bearing is as the first-selected supporting member of running shaft, and requiring has very high supporting rigidity and running accuracy, for this reason, must carry out pretension to bearing, to eliminate the play of bearing inside.So-called pretension applies a thrust load to bearing exactly, the play of bearing inside is eliminated, and made the certain predeformation of generation between rolling element and the inside and outside lasso, is in impaction state.The pretension amount should rationally determine according to the stand under load situation of bearing and usage requirement, and is excessive, can cause bearing wear and heating, reduces bearing life, even stuck and cause equipment failure.Therefore the pretension of bearing seems extremely important in modern industry is produced.Usually, adopt screw pair to come preloaded bearing, promptly process internal thread processing on the axle on outside thread or the bearing hole, screwing on nut or on bearing hole, screw in outer nut on the axle then, the pretension amount of regulating bearing by the pretightening force of control screw pair.At this moment nut or outer nut play locking effect.
Because the part that runs up of equipment is wanted good lubrication, with the working life and reduction noise, raising mechanical efficiency that prolongs equipment, at casing domestic demand contain lubricant oil, the lubricated of bearing itself mostly selected lubricating grease for use, and having to lubricate just has sealing, therefore, a lot of these type of machinery require pre-load nut to have the function of pretension and sealing simultaneously, and conventional nut is a steel part, has only the pretension locking functions, no sealing function.
Summary of the invention
The purpose of this utility model is to provide the Multifunction nut that a kind of energy pretension is locking, seal, eliminate axial clearance.In preloaded bearing, the sealing axle head is eliminated the gap that produces because of component long-term operation wearing and tearing back, thereby prolongs the expectation function and the life-span of equipment.
The utility model is achieved in that it comprises nut body, glue limit, and the supporting surface end of described nut body is provided with seam, on the seam of glue limit attached to nut body.
Locking and the sealing function of the utility model tool simultaneously, by the distortion of compressed glue limit recovered part, is eliminated the axial clearance between component, guarantees the original pretension of bearing, thereby does not reduce the running accuracy of bearing.

Embodiment
Embodiment 1:
It comprises nut body 1, glue limit 3, and the supporting surface end of described nut body 1 is provided with seam 2, on the seam 2 of glue limit 3 attached to nut body 1.
Nut body 1 can be various standards and non-standard nut, the nut that preferably has certain thickness flange, so that flange can process a seam at the supporting surface end, increase the area of contact of glue limit 3 and nut body 1, thereby increase the adhesion of glue limit 3 and nut body 1.
As: the automobile drive axle master subtracts the driving gear rotating speed height of assembly, require high running accuracy and rigidity, forward and backward have inside and outside bearing as supporting member, locate as the shaft shoulder by subtracting shell the outer ring of bearing, and pretightening force is born in the compression by spacer between bearing inner race, pretightening force is located and born to the inner bearing inner ring by back of tooth location, outer bearing inner ring by flange, and the size of final pretightening force is by the moment decision that is applied on the flange nut.Conventional nut is a single structure, because of Young's modulus is big, is difficult to compression, so have only the locking effect of pretension, on the function of whole back axle, then requires nut herein to have sealing concurrently, eliminate the function in gap.The utility model mainly is the compression by the glue limit, and nut and supporting surface are fitted closely, reaches seal action, and because of the glue limit is compressed, when axial clearance, the glue limit can partly be recovered distortion and be eliminated this gap.
It is material that synthetic rubber is adopted on glue limit 3, and durable wear, but repeated disassembled and assembled are reused.Vulcanization die is simple, and the glue limit easily is shaped.
Claims (3)
1. Multifunction nut, it comprises nut body (1), glue limit (3), it is characterized in that: the supporting surface end of described nut body (1) is provided with seam (2), on glue limit (3) seam (2) attached to nut body (1).
2. a kind of Multifunction nut according to claim 1 is characterized in that: the seam face good bond of the seam (2) of glue limit (3) and nut body 1 forms an integral body.
3. a kind of Multifunction nut according to claim 1 and 2 is characterized in that: glue limit (3) adopt synthetic rubber is material.
