Description
Technical field
The present invention relates to power transmission fields, i.e. toothed plate type yielding coupling.
Background technique
In the prior art, there are many yielding coupling type, there is Quincunx elastic coupler, star-like yielding coupling, Buddhist nun
Dens draconis yielding coupling, elastic grid coupling etc., yielding coupling, which is mainly used in load in transmission process, greater impact
Occasion, it be capable of absorbing load generate shock loading, filter the peak load part in shock loading.Protect primary drive
Component and prime mover be not by the injury of shock loading, and therefore, this kind of shaft coupling is applied very extensively in practice, largely makes
Used in pump group, blower unit, speed reducer drive system, diesel power systems, ship power system etc..These shaft couplings subtract
Shake effect is mainly completed by elastic element therein, these elastic element main materials are polyurethane, rubber, nylon etc.,
It is limited by the intensity of these materials itself and the structure of elastic element, for the very big unit of high-power, shock loading, these connection
Often service life is very short for axis device, or even cannot play the role of shock absorbing, is unable to satisfy the demand of applying working condition, the invention
Toothed plate type yielding coupling is applied primarily in engineering machinery that diesel engine is to the transmission between gearbox, since engineering machinery is being applied
Operating condition is severe during work, and shock loading is very big, and service life requirement is very high, so existing yielding coupling can not
Meet the requirement of operating condition, the connection of diesel engine and gearbox uses direct-connected or connected with spring coupling in original engineering machinery
It connects, larger for shock loading, spring often damages, and increasing spring, to will cause rigidity again excessive, and cushion performance deficiency damages it
His transmission parts.Therefore, inventing a kind of high resiliency, large torque, the high-elastic coupler of long-life has practice significance.
Summary of the invention
The purpose of the present invention is provide a kind of high resiliency, large torque, the toothed plate type of long-life elasticity in view of the above deficiencies
Shaft coupling.
The technical solution of the invention is as follows: toothed plate type yielding coupling, it is characterised in that including it is concentric from inside to outside
Outer tooth plate and internal gear, outside, inner hole is along the spaced multiple internal tooths of surrounding for internal gear；Including outer tooth plate, corresponding external tooth
The spaced multiple external tooths in plate outer surface, external tooth are inserted between two internal tooths, and are inserted with shock absorbing resilient between external tooth 7 and internal tooth
There have been the positioning pressuring plate of pressuring action in body, shock absorbing resilient body two sides；Outer tooth plate inner hole is connect with load-side, the outer round belt of internal gear 1
There is positioning spigot, is connect with engine flywheel.
In above scheme,
There is sealing ring 4 between positioning pressuring plate 5 and outer tooth plate 3.
Internal gear 1, outer tooth plate 3 are disc structure.
Shock absorbing resilient body 2 is cylindrical structure.
The invention has the advantages that experimental verification of the 1, present invention by 5000 hours on power 140kW bull-dozer, whole
Occur in a duty cycle without shaft coupling failure, meanwhile, in the monitoring by input load and output loads to shaft coupling,
It can be seen that impact loading has very high filter capacity, effect is more satisfactory.2, the present invention is mainly applied to engineering machine
In the main transmission of tool, existing spring coupling can be replaced after product Success in Experiment extensively, greatly improves engineering machinery
The service life and impact resistance of shaft coupling.It has broad application prospects and very high economic benefit.3, using internal gear
And outer tooth plate and between be put into shock absorbing resilient body, have the characteristics that high resiliency, large torque, improve the impact resistance of shaft coupling,
Extend the service life of shaft coupling.
Embodiments of the present invention are described in further detail below in conjunction with attached drawing.
Detailed description of the invention
Fig. 1 is structure of the invention simplified schematic diagram.
Fig. 2 is Fig. 1 side profile structure schematic diagram.
Specific embodiment
Referring to Fig. 1,2, parts title is as follows: internal gear 1, shock absorbing resilient body 2, outer tooth plate 3, sealing ring 4, positioning pressuring plate
5, internal tooth 6, external tooth 7, positioning spigot 8
Referring to Fig. 1,2, toothed plate type yielding coupling, including concentric outer tooth plate 3 and internal gear 1 from inside to outside, internal gear 1 exists
Outside, outer tooth plate 3 are disc structure in inner face, internal gear 1, outer tooth plate 3.Its inner hole of internal gear 1 is circumferentially spaced multiple
Internal tooth 6(pillar).Including outer tooth plate 3, the corresponding outer spaced multiple external tooth 7(pillars of 3 outer round surface of tooth plate), external tooth 7 is inserted in
Cylindrical shock absorbing resilient body 2(polyurethane, rubber or nylon are inserted between two internal tooths 6, and between external tooth 7 and internal tooth 6), subtract
Shake 2 two sides of elastomer have had the positioning pressuring plate 5(of pressuring action such as to pass through screw, be bolted).Positioning pressuring plate 5 and outer tooth plate 3
Between have sealing ring 4.
Outer 3 inner hole of tooth plate is connect with load-side, and 1 outer circle of internal gear has positioning spigot 8, is connect with engine flywheel.
1 bore design of internal gear has positioning spigot 8, connect with engine flywheel at a kind of toothed plate type structure, outer circle.Outside
3 outer circle of tooth plate is similarly designed to toothed plate structure, is used cooperatively with internal gear 1.Damping is put between internal gear 1 and outer tooth plate 3
Elastomer 2, outer tooth plate 3 connects load-side, after load is transmitted to outer tooth plate 3, need by after 2 damping of shock absorbing resilient body again
Internal gear 1 is passed to, to realize the effect of filtering and the torque transmitting of shock loading.Sealing ring 4 realizes seal protection effect,
And positioning pressuring plate 5 is realized and is acted on the positioning compression of shock absorbing resilient body 2.
It is described above, only a specific embodiment of the invention, it is various to illustrate not content structure for the essence of the present invention
At limitation.
