Description
Technical field
The present invention relates to a kind of locking mechanisms, especially tight for high revolving speed, large torque, high vibration frequency, space structure
The locking mechanism of the mechanical rotary device to gather.
Background technique
The compact mechanical rotary device of space structure is under high speed rotation, because of high revolving speed, high vibration frequency and large torque
Effect, locking nut often occur axial displacement and cause work mechanism not normal and serious accident.
Traditional locking mode has following several, and the scope of application and feature are summarized as follows:
1. the end face in hex nut adds spring washer, this kind of mode is only used for the slow-speed of revolution, low vibration frequency, small torque
Mechanical structure product in；
2. on screw thread sleeving and riveting several points, this kind of mode be only used for low vibration frequency, small torque mechanical structure product in；
3. add plain washer in the end face of hex nut, the inner hole of plain washer be it is non-round, the axis to match with plain washer it is outer
Circle is similarly non-round, plain washer is bent to resist an angle of hex nut, this kind of mode is only used for the machine of small torque
In tool infrastructure product, and processing technology is at high cost；
4. processing cotter-pin hold on nut and axis, split pin is filled, this kind of mode is limited by Design of Mechanical Structure, in ruler
It can not be assembled in very little space.
Summary of the invention
The technical problem to be solved by the present invention is a kind of locking mechanism of high-speed rotating machine device is provided, it is easy to process,
Structure is simple, is not limited by a space, and can guarantee the compact mechanical rotating dress of high revolving speed, large torque, high vibration frequency, space structure
The locking set.
The present invention is achieved by the following technical programs:
A kind of locking mechanism of high-speed rotating machine device, including axis, the nut and locking plate being connect with axle thread；
The axis includes connected thread segment and non-threaded section, and non-threaded section of outer diameter is greater than thread segment outer diameter, and screw thread
There is an annular groove coaxial with axis between section and non-threaded section, the key along axis axial direction is provided on the circumferential surface of the thread segment
Slot；
The first notch along end face radial direction is provided on one end face of the nut, other end is planar；
The locking plate is the strip thin slice of bending two ends；
The thread root of the axle thread section is greater than the thickness of locking plate to the depth dimensions of keyway slot bottom, and is less than lock
The width dimensions of piece.The depth dimensions of the thread root of axle thread section to keyway slot bottom are greater than locking plate thickness, guarantee locking plate
It can be loaded into；Depth dimensions are less than locking plate width dimensions, and limitation locking plate is flipped in use.
The keyway has two, and 1/4 perimeter is spaced on thread segment circumferential surface.
The quantity of first notch is more than one.Such case is had in actual use: when nut is screwed to required position
When setting, locking plate misalignment nut notch just must be tightened or be loosened again to nut, be unfavorable for installing.Therefore multiple slots are opened
Mouthful, the generation of above situation in the case where guaranteeing nut strength, can be avoided (because notch is more, even if locking plate fails just
Nut notch position is arrived well, also need to only tighten and loosen slightly, does not influence the stability of assembly).
The depth dimensions of the thread root of the axis to keyway slot bottom are 0.3mm bigger than the thickness of locking plate.
As long as the present invention processes keyway in the end of thread of axis, the depth dimensions of thread root to the keyway bottom of axis are greater than lock
The thickness of piece, and it is less than the width dimensions of locking plate, the locking mechanism is simple, easy to process；As long as one end of nut is slotted,
As long as its groove width can guarantee that locking plate can enter in slot；Because three locking plate, axis, nut parts become under the connection of locking plate
One, so can guarantee the locking of the compact mechanical rotary device of high revolving speed, large torque, high vibration frequency, space structure.
Compared to existing locking mechanism, the present invention is easy to process, and structure is simple, is not limited by a space, and can guarantee high turn
The locking of the compact mechanical rotary device of speed, large torque, high vibration frequency, space structure.

Specific embodiment
The invention will be further described with specific embodiment with reference to the accompanying drawing:
As shown in Figure 1, locking plate 2 passes through the keyway of axis 1, two ends of locking plate 2 are bent, and wherein one end is butted on 3 end face of nut
The first notch in, the other end is placed in annular groove, by the planar end of nut 3 be pressed in non-threaded section on axis 1 end face it
Between, to locking nut 3 and axis 1 for one.
Fig. 2 and Fig. 2 a shows 3 structure of nut of the invention, is opened on an end face of the nut 3 there are six the first notch,
Facilitate the tightness of adjusting nut 3, as long as the width of the first notch guarantees that locking plate 2 can be packed into, the other end is in planar
State.In the inner hole for axially extending to nut 3 of first notch from end face along nut 3 (i.e. the depth direction of notch).
Fig. 3 and Fig. 3 a shows the structure of axis 1 of the invention, and axis 1 includes connected thread segment and non-threaded section, non-threaded
The outer diameter of section is greater than thread segment outer diameter, and has an annular groove coaxial with axis 1 between thread segment and non-threaded section, thread segment
Two keyways axial along axis 1 are provided on circumferential surface, angle between the two is 90 degree.The thread segment thread root of axis 1 is to key
The depth dimensions of slot groove bottom are greater than the thickness of locking plate, and are less than the width dimensions of locking plate, and the setting of two keyways is convenient
The tightness of adjusting nut 3.
The structure of locking plate 2 of the invention is one or three sections of broken line compositions, and 2 main body of locking plate is strip thin slice.2 both ends of locking plate are curved
Song, width dimensions are greater than the thread root of axis 1 to the depth dimensions of keyway bottom.
