Description
Technical field
This utility model relates to a kind of machine driving device, and specifically, this utility model relates to a kind of shaft coupling, especially
It is that one can antioverloading shaft coupling.
Background technology
Shaft coupling is a kind of general-purpose device, is widely used in the mechanical transmission mechanisms such as water pump, blower fan, reductor transmission and turns round
Square.The machenical coupling of prior art is distinguished by version mainly friction-type and the big class of inserted type two, and wherein friction-type is again
There is dividing of brake shoe formula, piston ring type, torsion spring type, chip, block formula, circular cone type and strap of the brake formula；Inserted type is divided into castellated, keyed, tooth
Formula and ratchet-type.The shaft coupling technology maturation of these commercializations, complete in specifications, it is possible to meet wanting of corollary apparatus transmission moment of torsion
Ask.But, prior art products structure is relative complex, antioverloading scarce capacity, there is poor reliability in using, and maintenance difficulty etc. shows
Real problem, these problems seriously restrict the expansion in supporting market.
Utility model content
This utility model, mainly for the relative complex problem of prior art antioverloading scarce capacity and structure, proposes one
Simple in construction, install easily, reliable transmission, antioverloading shaft coupling that safety is good.
This utility model is achieved through the following technical solutions technical goal.
Antioverloading shaft coupling, it includes housing, driving disc spacing pressing, steel ball, pad, spring and follower disk.Described housing is split
The component of structure, is positioned at half and half housing of left and right end and is tightened by bolts and forms.Described driving disc spacing pressing and follower disk pairing are placed in shell
Among intracoelomic cavity, both built-in axial hole are coaxial.It thes improvement is that: on the faying face of described driving disc spacing pressing and follower disk
Uniform 6～12 pits matched and set on same circumference, the pit being located on driving disc spacing pressing end face is semicircle, is located at follower disk
Pit on end face is blind cylindrical hole, disposes and formed embedded elastic bearing by steel ball, pad and spring in the pit of pairing
Antioverloading structure.
As further improvement project, semicircular recess radius R uniform on described driving disc spacing pressing end face is than supporting steel ball half
Footpath big 0.25～0.5mm, the deep H of semicircular recess is than supporting steel ball radius little 0.20～0.30mm, semicircular recess edge rounding
Angle.
As further improvement project, cylindrical pit diameter D uniform on described follower disk end face is more straight than supporting steel ball
Footpath big 0.10～0.30mm, each cylindrical pit depth is identical.
As further improvement project, described steel ball size increases with transfer of torque and strengthens, φ 8.0～φ 30mm it
Between select one and choose.
This utility model compared with prior art, has the positive effect that:
1, the embedded elastic bearing being made up of steel ball and spring, simple in construction, making are easily；
2, there is overload moment, between driving disc spacing pressing and follower disk, occur nonsynchronous relative motion, i.e. follower disk static, and
Driving disc spacing pressing continues to rotate, and now steel ball overcomes the elastic force of spring to be fully sunk in follower disk pit, thus completes overload and protect
Protect, whole protection polyvinyl chloride, reliable, it is to avoid the overload damage to corollary equipment
3, after overload eliminates, steel ball is in time from the pit Elastic of follower disk so that driving disc spacing pressing rotation Tong Bu with follower disk
Turn, automatically reset, reduce management cost.
Accompanying drawing explanation
Fig. 1 is this utility model structural profile schematic diagram.
Fig. 2 is the Facad structure schematic diagram of driving disc spacing pressing in Fig. 1, is provided with 8 semicircular recess in figure.
Fig. 3 is the side cross sectional views of Fig. 2.
Detailed description of the invention
Below according to accompanying drawing and in conjunction with the embodiments, the utility model is described in further detail.
Antioverloading shaft coupling shown in Fig. 1, it includes housing 1, driving disc spacing pressing 2, steel ball 3, pad 4, spring 5 and follower disk 6.
Described housing 1 is the component of Split type structure, is positioned at half and half housing 1 bolt 1.1 locking of left and right end and forms.Described driving disc spacing pressing 2
Being placed among housing 1 inner chamber with follower disk 6 pairing, both built-in axial hole are coaxial.Driving disc spacing pressing 2 and the combination of follower disk 6
On face on same circumference uniform 6～12 match and be provided with pit, the pit being located on driving disc spacing pressing 2 end face for semicircle, if
Pit on follower disk 6 end face is blind cylindrical hole, disposes and formed embedding by steel ball 3, pad 4 and spring 5 in the pit of pairing
Enter formula flexibly mounted antioverloading structure.The present embodiment is used for 120m3/ h centrifugal pump and the connection of necessary electromotor, because specification is inclined
Little, therefore the steel ball 3 of 8 φ 10mm of selection is as driving member, uniform semicircular recess radius R=on supporting driving disc spacing pressing 2 end face
5.3 ± 0.05mm, the deep H=4.9 ± 0.05mm of pit, pit edge rounding.Uniform 8 D=10 on supporting follower disk 6 end facePit, joined pit depth is equivalently-sized.
This utility model product is installed when putting and make the transmission of normal moment of torsion in place, and under the elastic bearing of spring 5, steel ball 3 is situated between
Between driving disc spacing pressing 2 and follower disk 6.Once transshipping, between driving disc spacing pressing 2 with follower disk 6, moment occurs nonsynchronous relative
Motion, i.e. follower disk 6 is static, and driving disc spacing pressing 2 continues to rotate.Now steel ball 3 overcomes the elastic force of spring 5 to be fully sunk in servo-actuated
In dish 6 pit, thus completing overload protection, whole protection act is quick, reliable, it is to avoid the overload damage to corollary equipment.When
After overload eliminates, under the resiliency urged of spring 5, steel ball 3 ejects in time from the pit of follower disk 6 so that driving disc spacing pressing 2 with
Moving plate 6 synchronous rotary.This utility model product can automatically reset, and greatly reduces management cost.
