Description
Technical field
The utility model is related to the spline coupling used in a kind of shaft coupling, more particularly to a kind of pit gear.
Background technology
At present, shaft coupling is divided into cog-wheel coupling and yielding coupling substantially in structure function, because cog-wheel coupling
Can be bigger bear load impacting and live load, it is more safe when making startup or load uneven, and yielding coupling passes through bullet
The Flexible Transmission of spring absorbs substantial amounts of vibration force, so each play a different role.
The spline coupling inner ring of prior art, outer ring are overall, are had the following disadvantages on connecting mode：Inner ring with
Connecting shaft interference fit, heating are installed, uneven heating makes that pressure is uneven therewith, influence can be produced on product after heating, dismounting
Removed by force after Shi Bixu heating, often tear one-time mechanical hydraulic performance decline open, added up successively, easily cause surface and pull.If in drive division
Some parts and shaft coupling be damaged in itself, integral inner ring, outer ring spline coupling remove it is especially difficult, it is necessary to edge
Axial movement could remove spline outer ring, inner ring, and need very big pulling force when removing inner ring.Especially in underground in use, by
In the reason such as installing space is limited, crane capacity is not enough, to overhaul or change the parts that are damaged in drive division bring it is very big
Difficulty.
The content of the invention
The purpose of this utility model is to need hot charging to solve existing spline coupling installation process, and process is complicated, dismounting
There is provided a kind of spline shaft coupling of novel mechanism for the problem of mechanical performance is reduced after the problem of difficulty is big, and multiple dismounting hot charging
Device, frock requires low, simple to operate, and shaft coupling performance can be used for a long time mounting means without influence.
To achieve these goals, the technical scheme that the utility model is used is the advantage installed using combined type, will
The inner ring of existing spline coupling and outer ring are designed as dividing equally symmetrically arranged two halfbody structures vertically, are installed by bolt
Combination.
It is evenly arranged with the utility model combined flower key coupler, including inner ring and outer ring, affiliated interior ring outer wall convex
The keyway that the spline raised with ring outer wall in inner ring is engaged, its feature are evenly arranged with the spline structure risen, inner ring inwall
It is：Inner ring and outer ring are installed by separated two halfbody structures combination to be constituted；Described two that constitute inner ring or outer ring
Halfbody structure, is constructed identical；Spline or shaft with key way on described composition inner ring or the halfbody structure of outer ring are arranged symmetrically, side
Offered on mounting surface and the screw thread that is engaged with bolt installation through-hole is offered on bolt installation through-hole, opposite side mounting surface sink
Hole；Described composition inner ring or two halfbody structures of outer ring, inversion type are installed, the bolt installation through-hole in a halfbody structure
Coordinate respectively with the screw-threaded counterbore in another halfbody structure and bolt installation through-hole with screw-threaded counterbore and align, be bolted
Combination is installed.
Bolt installation through-hole and screw-threaded counterbore on described inner ring or the halfbody structure of outer ring is axial along inner ring and outer ring
It is vertically arranged, is laid along the center of wall thickness.
Screw-threaded counterbore and bolt installation through-hole on described inner ring or the halfbody structure of outer ring are symmetrical arranged along axle center.
Bolt counter sink is opened up on bolt installation through-hole on described inner ring or the halfbody structure of outer ring.
The beneficial effects of the utility model are：Processing and manufacturing simple in construction is simple, and cost is low；Easy installation and removal, nothing
Heating is needed, installing/dismounting task can be completed using simple Wrench, installing/dismounting operating efficiency is high；Shaft coupling uses gap
Install, installing/dismounting process is without heating, it is to avoid influence of the hot dismounting to the precision and performance of product, make the axle surface stress equal
It is even, couple more safe and reliable；This shaft coupling construction combines the spy that cog-wheel coupling moment of torsion is big and yielding coupling flexibility is high
Point, protecting against shock, vibration damping, live load are easy to maintenance more suitable for the connection of large-scale shaft coupling, and repeat dismount it is lossless,
It can be used for a long time, reduce production cost.
