Abstract
The utility model provides a special lock nut of bevel gear, including the nut body, nut body inner circle is provided with the internal thread, offers the first breach that two symmetries set up along internal screw thread axial direction, and nut body outer lane is provided with first step portion and second step portion, has offered the second breach in the axial direction of the periphery of first step portion, and the thickness of second step portion is less than the thickness of first step portion. The utility model discloses lock the nut in the bevel gear concave surface easily, but also have locking function.
Description
Technical Field
The utility model relates to a lock nut field, in particular to special lock nut of bevel gear.
Background
As shown in fig. 1, when a bevel gear in the prior art is to be installed at an end of a rotating shaft, it is difficult to lock the bevel gear at the end of the rotating shaft by using a common external hexagonal nut, and since a locking surface of the bevel gear is a concave surface, when the nut is located in the concave surface, the nut cannot be rotated by using a wrench, so that the nut is very difficult to lock, and the nut is easy to loosen after long-term use.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing an easily lock nut in bevel gear concave surface, the special lock nut of bevel gear that locking function is good moreover.
In order to achieve the above object, the present invention provides the following technical solutions:
the utility model provides a special lock nut of bevel gear, includes the nut body, and nut body inner circle is provided with the internal thread, offers the first breach that two symmetries set up along internal screw thread axial direction, and nut body outer lane is provided with first step portion and second step portion, has offered the second breach at the axial direction of the periphery of first step portion, and the thickness of second step portion is less than the thickness of first step portion.
The second breach is provided with four, and is the annular array and arranges at first step periphery.
The utility model has the advantages that:
the utility model has the advantages that the second notch is arranged, the effect of rotating the locking nut can be achieved by knocking the second notch in the locking process, and thus when the locking nut is positioned in the concave surface of the bevel gear, the locking nut can be further locked by knocking the second notch;
in addition, the thickness of the second step part is thin, so that the thread of the locking nut is single-side thinned, the locking nut is used for knocking the second step part of the locking nut through the aluminum bar after locking, two first notches which are symmetrically arranged are formed in the axial direction of the internal thread, and the locking nut is used for slightly deforming the second step part when receiving the knocking of the aluminum bar, so that the loosening condition after the locking of the nut can be prevented.
Drawings
FIG. 1 is a schematic cross-sectional view of a bevel gear;
fig. 2 is a schematic diagram of the right-side structure of the present invention;
FIG. 3 is a schematic cross-sectional view taken at A-A of FIG. 2;
fig. 4 is a schematic sectional view of the bevel gear assembled on the rotating shaft according to the present invention.
Detailed Description
The invention is further explained below with reference to the drawings:
as shown in fig. 1 to 4, a lock nut special for a bevel gear comprises a nut body, wherein an inner ring of the nut body is provided with an internal thread, two first notches 2 symmetrically arranged are formed in the axial direction of the internal thread, a first step portion 3 and a second step portion 4 are formed in the outer ring of the nut body, a second notch 5 is formed in the axial direction of the outer periphery of the first step portion 3, and the thickness of the second step portion 4 is smaller than that of the first step portion 3.
The second notches 5 are four and are arranged on the periphery of the first step 3 in an annular array.
The utility model has the advantages that the second notch 5 is arranged, the effect of rotating the locking nut can be achieved by knocking the second notch 5 in the locking process, and thus when the locking nut is positioned in the concave surface of the bevel gear, the locking nut can be further locked by knocking the second notch 5;
in addition, the thickness of the second step part 4 is small, so that the thread of the locking nut is single-side thinned, the locking nut is used for knocking the second step part 4 of the locking nut through the aluminum bar after being locked, two first notches 2 symmetrically arranged in the axial direction of the internal thread are formed, the locking nut is used for slightly deforming the second step part 4 when receiving the knocking of the aluminum bar, and the situation that the nut is loosened after being locked can be prevented.
The above description is not intended to limit the technical scope of the present invention, and any modifications, equivalent changes and modifications made to the above embodiments according to the technical spirit of the present invention are all within the scope of the technical solution of the present invention.
