Description

A kind of yielding coupling

Technical field

This utility model is related to shaft coupling and in particular to a kind of yielding coupling.

Background technology

Shaft coupling belongs to mechanical spare part in common use category, for connect two axles in different institutions be allowed to jointly rotate with The machine components of transmitting torque.

Shaft coupling mainly includes positive coupling and yielding coupling.Positive coupling structure is simple, low price, is suitable for In the good situation of two shaft concentricities；Yielding coupling is applied to the not good situation of two shaft concentricities, can transmit larger turn Square is it is allowed to have larger comprehensive displacement and higher rotating speed, less demanding to installation accuracy, but complex structure, assembling unloading Waste time and energy.Operationally, two axles produce relative displacement, and yielding coupling flank of tooth periodicity makees axially opposing slip, permanent worker After work, the flank of tooth can produce abrasion.After existing yielding coupling tooth surface abrasion, typically shaft coupling is entirely changed, caused material Waste.And some adopt the high elastic rubber disk shaft coupling of rubber, though can be changed after the abrasion of tooth class, assembly and disassembly operations is stranded Difficult.

Utility model content

A kind of shortcoming that this utility model aims to overcome that above-mentioned prior art, there is provided yielding coupling, structure letter Single, lightweight, it is good to be fixedly connected effect, and assembles and unload carried convenient.

(2) technical scheme

A kind of yielding coupling, including top cover, outer disk, moulding, becket, internal ring it is characterised in that：Described outer disk, The sequentially coaxially heart is fitted together to from outside to inside for moulding, becket and internal ring；Described outer disk is annular, and inner side is provided with outer disk tooth, The section of outer disk tooth uniformly increases vertically；Described moulding is annular rubber part, and periphery is provided with one-to-one with outer disk embedding The moulding tooth entering, the section of moulding tooth is identical vertically；It is provided with conduit inside described moulding；Set outside described internal ring It is equipped with conduit；Described top cover is disk, and there is through hole at center；Described top cover is concentric with outer disk to link together.

Preferably, the minimum shape of described outer disk tooth and the size profile of moulding tooth are identical.

Preferably, described internal ring is rubber parts, has breach, and there is cotter way inner side.

Preferably, described becket and internal ring have 3 corresponding screwed holes respectively.

Preferably, described top cover through-hole diameter is less than moulding external diameter, more than becket external diameter.

Preferably, described top cover is located at the minimum side of outer disk tooth.

(3) beneficial effect

Profile of tooth of the present utility model is fitted together to has taper it is ensured that the elastic buffer effect of shaft coupling.Moulding assembling or Easy to operate during unloading, and while ensureing to be connected effect, effectively reduce product weight.

Brief description

In order to be illustrated more clearly that the technical scheme of this utility model embodiment, will make to required for embodiment description below Accompanying drawing be briefly described it should be apparent that, drawings in the following description be only some embodiments of the present utility model, For those of ordinary skill in the art, on the premise of not paying creative work, can also obtain according to these accompanying drawings Other accompanying drawings.

Fig. 1 is lower view of the present utility model；

Fig. 2 is top view of the present utility model；

Fig. 3 is the sectional view in the F-F direction along along Fig. 2

In accompanying drawing, the list of parts representated by each label is as follows：

1- internal ring, 101- cotter way, 102- screwed hole, 2- becket, 3- outer disk, 301- screwed hole, 302- outer disk tooth, 4- pushes up Lid, 5- moulding, 501- moulding tooth.

Specific embodiment

Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out Clearly and completely description is it is clear that described embodiment is only a part of embodiment of this utility model rather than whole Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under the premise of making creative work The all other embodiment being obtained, broadly falls into the scope of this utility model protection.

Refering to shown in Fig. 1, Fig. 2, Fig. 3, this utility model is a kind of yielding coupling, including top cover 4, outer disk 3, moulding 5, becket 2, internal ring 1.The sequentially coaxially heart is fitted together to from outside to inside for outer disk 3, moulding 5, becket 2 and internal ring 1.In moulding 5 Side is provided with conduit, blocks outside becket 2.It is provided with conduit outside internal ring 1, block inside becket 2.Top cover 4 is disk, There is through hole at center, and through-hole diameter is less than moulding 5 external diameter, more than becket 2 external diameter.Outer disk 3 is annular, and inner side is provided with outer Disk tooth 302, the section of outer disk tooth 302 uniformly increases vertically.Moulding 5 is annular rubber part, and periphery is provided with and outer disk 3 One-to-one embedded moulding tooth 501, moulding tooth 501 section is identical vertically.Moulding tooth 501 is minimum with outer disk tooth 302 The size profile of shape is identical.Internal ring 1 is rubber parts, has breach, and there is cotter way 101 inner side.Becket 2 and 1 point of internal ring There are not 3 corresponding screwed holes 102.Top cover 4 is concentric with outer disk 3 to be welded together, positioned at the side of outer disk tooth 302 minimum.

This utility model needs two and uses cooperatively.During use, axle is passed through the internal ring 1 of a shaft coupling, adjust phase Para-position postpones, and pin member is embedded in cotter way 101, and holding screw is threaded into hole 102, fixes becket 2 and internal ring 1.So Afterwards another axle is passed through the internal ring 1 of another shaft coupling.Adjustment shaft coupling relative position, makes the moulding 5 of two shaft couplings Staggered relatively, fixed using screw-driving after the screwed hole 301 of two shaft couplings of be aligned.Due to adopting moulding, and profile of tooth is embedding Close and there is taper it is ensured that the elastic buffer effect of shaft coupling.
