Description

Novel shaft end locking nut for hydraulic coupler
Technical Field
The utility model relates to a fastener, especially a new-type axle head lock nut for fluid coupling.
Background
When the hydraulic coupler operates, the pump wheel is driven by the input shaft to rotate, and the turbine and the output shaft are driven to rotate by the kinetic energy of the working liquid. The impeller can generate certain axial force when rotating, under the working conditions of large transmission power and high rotating speed, in order to bear the axial force, a structural mode of adding a thrust plate between two sets of thrust bearings which are oppositely arranged is adopted, the thrust plate is fixed on a shaft in a mode of adding a gasket and a nut, but sometimes, the machining precision deviation of the thread size on the shaft exists, and the phenomenon that the nut falls off can be caused under the action of the axial force, so that the axial size of the whole unit is changed, and the unit cannot normally operate. There is therefore a need for a method or apparatus that addresses the above-mentioned problems.
Disclosure of Invention
The utility model relates to a solve the above-mentioned not enough that prior art exists, provide a simple structure, design benefit, rationally distributed, low cost, and can effectively prevent the axle head lock nut for the fluid coupling that drops.
The technical solution of the utility model is that: the utility model provides a new-type axle head lock nut for fluid coupling ware, includes nut body 1, circles in nut body 1 and is provided with internal thread, its characterized in that: the nut body 1 is provided with gaps 2 distributed along the circumferential direction, the arc length of each gap 2 is one third of a circle, the width of each gap 2 is 0.1-0.2 times of the thickness of the nut body 1, the nut body 1 within the range of the gaps 2 is symmetrically provided with two threaded holes 3, the arc length between the two threaded holes 3 is one sixth of a circle, and bolts 4 are matched with the threaded holes 3.
Compared with the prior art, the utility model, have following advantage:
the novel shaft end locking nut with the structure is simple in structure, ingenious in design and reasonable in layout. It is to traditional nut problem that probably takes place to drop in the course of the work, improve traditional nut, make split type structure with some of nut to set up the screw hole in this department, after the nut screwed on the transmission shaft, let split type two parts nut be close to each other through the mode of the bolt of screwing, thereby change the internal screw thread concrete shape of nut, and then let the nut lock die on the transmission shaft, thereby reach and tightly decide the thrust plate, avoid thrust bearing to take place the condition that axial dimension changes. The locking nut has reliable locking effect, thereby improving the reliability of the hydraulic coupler and providing guarantee for the normal operation of the whole unit. And the manufacturing process is simple, the manufacturing cost is low, so that the novel LED lamp has multiple advantages, is particularly suitable for popularization and application in the field, and has a very wide market prospect.

Fig. 2 is a sectional view taken along line a-a in fig. 1.
Fig. 3 is a schematic view of an operating state of the embodiment of the present invention.
Detailed Description
The following description will explain embodiments of the present invention with reference to the drawings. As shown in fig. 1, 2, and 3: a novel shaft end locking nut for a hydraulic coupler comprises a nut body 1, wherein an inner ring of the nut body 1 is provided with an internal thread, the nut body 1 is provided with a gap 2 distributed along the circumferential direction, the arc length of the gap 2 is one third of a circle, the width of the gap 2 is 0.1-0.2 times of the thickness of the nut body 1, the nut body 1 in the range of the gap 2 is symmetrically provided with two threaded holes 3, the arc length between the two threaded holes 3 is one sixth of a circle, and the threaded holes 3 are matched with bolts 4.
The working process of the novel shaft end locking nut for the structural form hydraulic coupler is as follows: firstly, a pair of thrust bearings 6 are arranged on an output shaft 5, a thrust plate 7 is arranged between the two thrust bearings 6, one end of the thrust plate 7 is positioned through a shaft shoulder on the output shaft, the other end of the thrust plate is propped against by a retainer ring 8, the nut body 1 of the nut is in threaded connection with the output shaft 5 and compresses the retainer ring 8, after the nut body 1 is screwed, two bolts 4 are screwed, due to the existence of a gap 2, the nut body 1 corresponding to the bolts 4 is actually divided into two pieces, and the two pieces are close to each other under the action of the bolts 4, so that the shape of an internal thread on the inner circle of the nut body 1 is changed, and the nut body 1 cannot rotate relative to the output shaft 5 due to the change of the shape of the internal thread, and further, the purpose of.
