Description
Technical field
The present invention relates to a kind of screw retention, more particularly to a kind of screw retention spacing using tooth form.
Background technology
In common bolt（Nail）In connection design, a variety of locking thread forms can be selected.As split pin is locking, punching point is protected
The standard anti-loose methods such as danger is locking, stop washer is locking and fuse is locking.These simple locking modes are by facts have proved
To common bolt（Nail）, nut connection be effective, connected for some unconventional large-diameter threads（As flying tail turns
The locking nut of axle and bearing connects）But not necessarily it is applicable.
Large-diameter thread connection is due to can produce larger frictional force, can only and because special structure type, space are limited
It is locking by being carried out after being suitably modified to the stop washer in above-mentioned locking mode.Either, using different from standard
Locking limited block design, i.e., fluting, the perforate respectively on two parts of screw thread engagement, ensure both with screw installation limited block
Between will not relatively rotate.But actually both modes are not ideal, its common drawback is needed in installation process
The rotational angle of adjusting nut, with ensure the curved tooth of stop washer either the stopper slot on the screw hole and nut of limited block or
Screw hole aligns.
Aforesaid operations get up sometimes extremely difficult, and degree of regulation is limited by stopper slot or hole number, in fact
Conventional locking thread, typically can be to be solved by cushioning circle there is also this problem, and tightness is easily controlled.But
Connected for large-diameter thread, especially the sleeve thread between flying tail rotating shaft and bearing is locking, then needing to overcome to add
Pad, clearance requirement are high and need the limitation of the factors such as accurate limiting, easy to operation, to design a kind of new locking thread
Device.
The content of the invention
The present invention needs to solve the problems, such as to be to provide a kind of screw retention spacing using tooth form.
To solve the technical problem of the present invention, the technical solution adopted by the present invention is：
A kind of screw retention spacing using tooth form, it includes tooth form limited block, movable block, dogbolt and locking
Nut, the surface of the tooth form limited block and the bottom surface of movable block are each formed with teeth groove, the center section of the tooth form limited block
Square three-way groove is provided with, tooth form is fixed in the bottom of the tooth form limited block formed with double wedge, the movable block by dogbolt
On the square three-way groove of limited block, the locking nut is placed on axle sleeve side, and oscillating bearing is installed outside the axle sleeve opposite side, described
Axle sleeve is placed in rotating shaft, and the double wedge of the tooth form limited block is caught in the neck of axle sleeve, and the movable block passes through teeth groove and tooth form
Limited block engages, and the dogbolt is directed at locking with the screwed hole opened in advance on locking nut.
The present invention sets tooth form limited block, it is contemplated that horizontal tail rotating shaft is high with bearing fit clearance requirement, using the spiral shell of routine
Nail positioning hole can not meet needs because precision is low, so as to select this brand-new design of tooth form limited block.Tooth form limited block has
Easy to adjust, the characteristics of precision is high, critical work is played to the accurate limiting of locking nut in horizontal tail rotating shaft installation process
With.
The present invention sets movable block, in order to coordinate tooth form limited block, in one piece of movable block of location arrangements of its fixing screws,
It is engaged with by teeth groove.The position of movable block is adjusted during installation can complete the accurate limiting of locking nut.This apparatus structure
Simply, it is easy to adjust, it is spacing accurate, breach the various limitations of Conventional limit block design.
Beneficial effects of the present invention：It is spacing to being carried out between locking nut and axle sleeve by tooth form limited block and movable block,
Both is realized locking thread without relative motion, and can be finely adjusted by tooth form limited block and the teeth groove on movable block, turned
Critical effect is played to the accurate limiting of locking nut in axle installation process, it is easy to adjust, it is spacing accurate.

Embodiment
The invention will be further described with specific embodiment below in conjunction with the accompanying drawings.Following examples are merely to illustrate this hair
It is bright, it is not limited to protection scope of the present invention.
Shown in Fig. 1 and 3, a kind of screw retention spacing using tooth form of the invention, it includes the He of tooth form limited block 4
Movable block 5, the surface of tooth form limited block 4 and the bottom surface of movable block 5 are each formed with teeth groove 8, and the pars intermedia of tooth form limited block 4 separates
There is square three-way groove 9, formed with double wedge 10, it is spacing that movable block 5 by dogbolt 6 is fixed on tooth form for the bottom of tooth form limited block 4
On the square three-way groove 9 of block 4, locking nut 3 is placed on the side of axle sleeve 7, installs oscillating bearing 2 outside the opposite side of axle sleeve 7, axle sleeve 7 is placed on
In rotating shaft 1, the double wedge 10 of tooth form limited block 4 is caught in the neck 11 of axle sleeve 7, and movable block 5 passes through teeth groove 8 and tooth form limited block 4
Engagement, dogbolt 6 are directed at locking with the screwed hole 12 opened in advance on locking nut 3.
The main body of the present invention is tooth form limited block 4 and movable block 5, and its effect is carried out between locking nut 3 and axle sleeve 7
It is spacing, both is realized locking thread, and can be carried out by tooth form limited block 4 and the teeth groove 8 on movable block 5 without relative motion
Fine setting.
Shown in Fig. 1 a, Fig. 1 b and Fig. 2, the faying face between tooth form limited block 4 and movable block 5 is engaged by teeth groove 8, then is used
Two dogbolts 6 are fixed.Square three-way groove 9 is outputed in the center section of tooth form limited block 4, to avoid producing with two dogbolts 6
Interference.Load path is by the Compressive activities block 5 of dogbolt 6, and the teeth groove on movable block 5 engages with the generation of tooth form limited block 4
Face extrudes, and is then delivered on the double wedge 10 of tooth form limited block 4.
Shown in Fig. 3, to ensure to be caught in the card of axle sleeve 7 without relative motion, tooth form limited block 4 between locking nut 3 and axle sleeve 7
After groove 11, the position of movable block 5 is adjusted, it is directed at the screwed hole 12 opened in advance on locking nut 3, and is fixed with dogbolt 6,
The degree of regulation of movable block 5 is related to the space width of teeth groove.
The inner ring of oscillating bearing 2 is inserted in rotating shaft 1 first, is fixed by axle sleeve 7 with locking nut, threaded engagement is twisted afterwards in place
Tightly, then tooth form stopping means is installed.During installation, the double wedge 10 of tooth form limited block 4 is caught in the neck 11 of axle sleeve 7, and movable block 5 is logical
Cross teeth groove 8 to be engaged with, and adjust its position and be aligned with the screwed hole 12 opened in advance on locking nut 3, two stop are finally installed
Bolt 6, tooth form stopping means is fixed on the outer ring of locking nut 3.The tooth form stopping means of the present invention realizes tooth form limit
Two bolts hole on the block 4 of position（Square three-way groove 9）No longer it is fixed, but can move about.
