Abstract
The friction type mechanical centrifugal clutch consists of one semi-coupling I, one semi-coupling II and one internal and external friction disc combination. The semi-coupling II has one inside fixing board and one external centrifugal pressure device; and the internal and external friction disc combination inside the semi-coupling II connects the semi-coupling I and the semi-coupling II. During operation, the centrifugal force of the weight dropper in the centrifugal pressure device is applied through a lever onto the friction discs. The present invention has simple structure, convenient maintenance, high reliability, environment friendship, no slip, capability of starting at heavy load, overload protection function and other advantages.
Description
Technical field
What the present invention relates to is machine foundation transmission part----coupling, particularly friction type centrifuge coupler.
Background technique
In the machinery, must link to each other with various coupling between prime mover and the working machine, the power of prime mover could be passed to working machine.The kind of coupling has a lot, and their great majority can only transmit certain moment of torsion, function singleness.Particularly work as machinery and operate in bad working environments, as heavy load starting, impact, overload, skidding, device fails etc., they all can not protect the machinery safe operation well.The fluid coupling coupling can address the above problem, but its volume is big, complex structure, with oily coupling, easy befouling environment, the slow-speed of revolution is used restricted, safeguards and adjusts inconvenience.Its in when work pump impeller and turbine between have speed discrepancy, so transmission efficiency and rotating speed can not reach 100%.Chinese patent ZL00237260 proposes a kind of limit square centrifugal coupling, it is to utilize pouring weight to produce centrifugal force to peripolesis, the friction plate of compressing periphery produces frictional force and plays coupling, because of the areal of friction facing of periphery certain, increase difficulty of torque ratio with area, adjust also inconvenient.Another Chinese patent ZL97243641 also proposes a kind of friction coupler, and principle is same as described above, but complex structure.Chinese patent ZL200620097061.5 has proposed a kind of friction type overload limited torque coupling, and it can solve the problem of overflow protection, but can not solve the problem of heavy load starting.
Summary of the invention
But the objective of the invention is to propose the friction type centrifuge coupler of a kind of simple in structure, easy to maintenance, safe and reliable, energy-conserving and environment-protective, no slippage heavy load starting.
The present invention realizes like this.It mainly contains half-coupling I, half-coupling II, interior outside friction disc group is formed.Fixed plate is equipped with in the inner at half-coupling II, and the outer end is fixed with centrifugal pressurization device, and interior outside friction disc is contained in the centre of half-coupling II, by it half-coupling II and half-coupling I is coupled together.
Centrifugal pressurization device is made up of weight, weight pin, lever pin, centrifugal seat ring, Returnning spring.Weight is installed in by weight pin on the free bearing of centrifugal seat ring, and the weight afterbody is pressed on the friction plate by lever pin.The number of weight is an even number, in order to avoid imbalance causes vibrations.
Working procedure of the present invention is such.Motor drives centrifugal pressurization device rotation by half-coupling II, low when beginning to rotate because of rotating speed, the centrifugal force that weight produces is very little, so the strength by lever pin compressing friction plate is also very little, this moment, friction plate skidded, motor and heavy duty the contact have been separated, so can make the motor light-load starting.When rotating speed raises gradually, centrifugal force strengthens, and the impacting force of friction plate is also strengthened, and mechanical coupler friction torque is also increased, and rotates together until be enough to drive load.Rotating speed rises to rating value again, and friction torque substantially exceeds the moment of torsion of load, so but just safe operation of entire equipment.Generally speaking, adjusting qualification maximum friction torque value is 1.2-2.5 times (the little value of underload is got big value during heavy duty) of load torque.When equipment was subjected to impact, overload, the overload moment of torsion was greater than the maximum friction torque value, and friction plate skids, thereby has protected the unlikely damage of equipment.The present invention just has Chinese patent ZL200620097061.5 the same service behaviour of friction type overload limited torque coupling.
When equipment stopped, rotating speed dropped to zero, and centrifugal force disappears, and weight is got back to initial position under the effect of Returnning spring.
Friction torque is greater than load torque during proper functioning, and friction plate is non-slip, so input end and output terminal synchronous operation do not have speed discrepancy, therefore, transmission efficiency of the present invention and rotating speed can reach 100%.
Improve the weight quality, reduce rated speed, the friction torque that centrifugal force is caused reaches designing requirement, and the present invention is moved under low rated speed.This performance is that fluid coupling is inaccessible.The present invention can make various types such as 1500 rev/mins of rated speeds, 1000 rev/mins, 750 rev/mins.To satisfy the requirement of different motors.
The present invention adjusts transmitted power or moment of torsion is also non-easily.The sheet number that increases friction plate has just increased transmitted power or moment of torsion easily.The same weight quality that increases also increases the impacting force to friction plate easily, has also increased the power or the moment of torsion that transmit within the specific limits.
Mechanical coupler of the present invention is safeguarded also very convenient, when find decreased performance more renewal of facing renewal can reuse, other part need not to change.
The present invention has tangible advantage, but that it has is easy to maintenance, safe and reliable, energy-conserving and environment-protective, no slippage heavy load starting, can solve the problem of low load with strong power, energy saving, working life is very long, need not oily coupling, free from environmental pollution, and the slow-speed of revolution is used unrestricted.
