Abstract
The utility model provides a pair of friction formula shaft coupling, driving shaft by tooth engagement drive external friction plate, under the effect of spring force, by the interior ring support of friction disc drive combination, combine young interior ring support to drive the driven shaft rotation by driving the shaft coupling seat, combining sub - disc. When load torque was greater than the moment of torsion (friction disc group can transmit friction torque ) of shaft coupling settlement, skidding appeared in friction disc indirect contact face, when load torque is less than or equal to the shaft coupling setting value, the normal transmission of shaft coupling. Transmit the big or small adjustable of moment of torsion: adjustment adjusting nut, it is big or small through the elasticity control spring power of compression and antagonistic spring, make friction disc group frictional force controllable, the size of moment of torsion is transmitted in the size decision of frictional force, has just so realized the big of control transmission moment of torsion.
Description
Technical field
This utility model relates to a kind of friction coupling.
Background technology
Shaft coupling is for two axles coupling in different institutions in machine driving, is allowed to turning round and transmitting moment of torsion
A kind of parts.Shaft coupling of a great variety, is summed up and is commonly divided into two big classes: positive coupling and flexible coupling.Just
Property shaft coupling do not compensate the ability of relative displacement, two coupled axles require strict centerings, and its structure is general the simplest, hold
Easily manufacture, bigger moment of torsion can be transmitted.Conventional positive coupling mainly has flange-face coupling, box coupling, pod shaft coupling
Device etc..Flexible coupling is divided into again have elastic component flexible coupling and Inelastic element flexible shaft coupling two kinds.Flexible shaft coupling
The feature of device is to have to compensate the ability that two axial lines offsets axially, radially, the most relatively in various degree.Inelastic component flexibility joins
The bearing capacity of axial organ is big, but does not possess buffer shock-absorbing performance, at a high speed or rotary speed unstabilization is fixed or during rotating, has impact and makes an uproar
Sound, therefore be applicable to low speed, load and the stable occasion of rotating speed.
Load in machine driving be there will be to over loading and the occasion of impact of ANOMALOUS VARIATIONS such as burst, selecting connection
During axial organ, protection equipment to be considered is without damage, and in this case generally selecting has the shaft coupling of overload protection performance, such as peace
Entirely sell shaft coupling.But pin safety coupling the most often there is the phenomenon that pin cuts off.After safety pin cuts off, although protection
The equipment such as chain, axle, but repair safety pin and but to take a long time, reduce production efficiency.
Utility model content
For solving above-mentioned technical problem, this utility model provides a kind of friction coupling, its objective is to provide one
Can automatically compensate, simple in construction, can realize being rapidly assembled and disassembled, the shaft coupling that easy to maintenance and maintenance time is short.
A kind of friction coupling, it includes driving shaft and driven shaft, also includes adjustment gland, and described driving shaft is worn
Toning seamless lid, described adjustment gland is linked together with shaft coupling seat by spring pull bar, and described driven shaft is through connection
Axial organ seat, described spring pull bar is connected to encapsulate on the spring in shaft coupling seat and by spring capping, described shaft coupling
Being provided with zygote disk in Zuo, the lower section of described zygote disk is provided with friction plate, and the lower section of described friction plate sets
It is equipped with ring support in zygote, the inner ring of described friction plate is provided with internal tooth, outside the outer ring of described friction plate is provided with
Tooth.
Preferably, it is provided with block between described zygote disk and shaft coupling seat.
Further preferably, described friction plate is rubber friction disc.
Further preferably, described spring capping is provided with spring nut.
A kind of friction coupling that this utility model provides, it has the beneficial effects that: driving shaft is by driving shaft coupling
Seat, zygote disk, driven outside friction disc by tooth engagement, under spring force, driven by friction plate and combine
Ring support in son, in zygote, ring support drives driven shaft to rotate.When moment of torsion (the friction plate group institute that load torque sets more than shaft coupling
Moment of friction can be transmitted) time, skidding occurs in friction plate mediate contact face；When load torque is less than or equal to shaft coupling setting value
Time, the normal transmission of shaft coupling.The size adjustable of transmission moment of torsion: adjust adjusting nut, by compression and the degree of tightness of pull-off spring
Controlling spring force size, make friction plate group frictional force controlled, the size of frictional force determines the size of transmission moment of torsion, thus realizes
Control the size of transmission moment of torsion；During further, ring support rubbing surface combines in friction plate and zygote, between have gap, machine oil can
Dynamic to reflux on rubbing surface, will not bonding die, be not easily formed vacuum between rubbing surface and rubbing surface, friction plate and knot in work
In zygote the combination of ring support with separate more smooth and easy, contact is more steady, also can increase coefficient of friction, and handling is more preferable, machine
Oil flows freely on rubbing surface, and cooling-down effect is more preferable.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will be to embodiment
Or the required accompanying drawing used is briefly described in description of the prior art.
Accompanying drawing 1 is this utility model structural representation；
Accompanying drawing 2 is the structural representation of friction plate in this utility model.
Detailed description of the invention
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 describe.
The present embodiment as depicted in figs. 1 and 2,
A kind of friction coupling, it includes driving shaft 1 and driven shaft 2, also includes adjustment gland 3, described active
Axle 1 is through adjusting gland 3, and described adjustment gland 3 is linked together with shaft coupling seat 5 by spring pull bar 4, described spring
Pull bar 4 is connected on the spring 6 in shaft coupling seat 5 and is encapsulated by spring capping 7, and described driven shaft 2 is through shaft coupling seat
