Description

It is capable of the yielding coupling of the impaired parts of quick-replaceable
Technical field
The invention belongs to mechanical transmission fields, specifically a kind of elastic shaft coupling for being capable of the impaired parts of quick-replaceable Device.
Background technology
In plant equipment, it must be connected between prime mover and working machine with various shaft couplings, could be dynamic by original The power of machine is transmitted to working machine.
The kind of shaft coupling has a lot, and the part zero because of machine usually occurs in existing shaft coupling in use Part damages, so need it is quick disconnect or the phenomenon of dismounting couplers, above-mentioned prior art not only install safeguard it is more complicated, And the waste of the undamaged parts of shaft coupling can be caused, economic benefit is relatively low.Meanwhile prior art is whole to shaft coupling progress It, it is necessary to first mobile device when body is changed, then will disassemble in shaft coupling slave unit, then shaft coupling could be re-installed in In equipment, after shaft coupling has been changed, it is also necessary to centering again is carried out to shaft coupling, i.e., it is time-consuming and laborious, not only influence production Be normally carried out, also add maintenance cost.
Such as in lift, steel rolling mill, building machinery and engineering machinery often with some are simple in construction, compact to design, The easy of machine or shaft coupling often occurs in the shaft coupling that inertia is small, easily assembles, the shaft coupling in the said equipment in use Parts damages are damaged, and then need the phenomenon of integral replacing shaft coupling, but the said equipment changes shaft coupling more difficult, maintenance time It is longer, it is necessary to carry out centering again to shaft coupling after shaft coupling has been changed, it is therefore necessary to be improved.
The content of the invention
The invention aims to overcome the weak point of background technology, and one kind is provided being capable of quick-replaceable impaired zero The yielding coupling of part, it is capable of the middle easily worn part of quick-replaceable machine or shaft coupling, installation safeguard it is simple more convenient, Economic benefit is higher.
To achieve these goals, the technical scheme is that:It is capable of the elastic shaft coupling of the impaired parts of quick-replaceable Device, it is characterised in that:Including central shaft, the slip cap that is set in central shaft one end and can slide on center shaft, it is set in Fixed cover in mandrel, is provided with slip position-limit mechanism between slip cap and central shaft, fixed cover both ends are arranged on by jump ring On central shaft;The slip position-limit mechanism includes block and spacing bearing pin, provided with the first spacing hole and with the in the slip cap Second spacing hole of one spacing hole connection, the aperture of the second spacing hole are more than the aperture of the first spacing hole, set on the central shaft There is annular spacing groove corresponding with second spacing hole, block, the pin of spacing bearing pin are installed at the port of the second spacing hole Shaft head is located in the second spacing hole and to form the shaft shoulder with the second spacing hole spacing, is provided with and is located between bearing pin head and block Spring in second spacing hole, bearing pin axis body one end of spacing bearing pin are connected with bearing pin head, and the bearing pin axis body of spacing bearing pin is another One end passes from the first spacing hole;The outer wall of the central shaft is provided with first that a circle is arranged in a ring and allows cutter groove, and first allows Cutter groove is between slip cap and fixed cover;The central shaft outer wall is provided with multiple sliding recess being circular layout, slip cap With the slide protrusion that is matched with the sliding recess is equipped with fixed cover.
In the above-mentioned technical solutions, the outer wall of the slip cap is provided with and is connected at the port of first spacing hole First stopper slot, and the second stopper slot with being connected at the port of second spacing hole, the bearing pin axis body of the spacing bearing pin The other end is located in the second stopper slot.
In the above-mentioned technical solutions, the block is the screw being connected with the port threads of the second spacing hole.
In the above-mentioned technical solutions, it is mounted on jump ring on the slip cap and fixed cover.
Allow cutter groove that slip cap and fixed cover can be made to rotate on center shaft between slip cap and fixed cover, be easy to The installation site of slip cap and fixed cover on center shaft is further adjusted, so as to improve the practical performance of the present invention.
When the present invention is in normal operating conditions, the bearing pin head of spacing bearing pin is the annular spacing groove positioned at central shaft Interior, the spring being now placed in the second spacing hole is in the most long state of length, and the bearing pin head of spacing bearing pin makes slip cap Interference is formed between central shaft, and then realizes limit function.When needing to change some parts of the present invention, staff The bearing pin axis body end of spacing bearing pin need to be only pressed, so as to which the spring in the second spacing hole is in the most short (pressure of length Contracting) state, now interference releases, and staff can slide into slip cap suitable position, the spare part more renewed, again The installation present invention.
The present invention is simple in construction, easy to operate, need to only change the parts being damaged on shaft coupling, save maintenance time, Operating efficiency is improved, reduces labor strength, extends the service life of equipment.
