Abstract
The present invention provides centrifugal brakes, including friction cylinder, rotor is provided in the friction cylinder, it is equipped between the rotor and friction cylinder and gets rid of block, for outer convex globoidal, this gets rid of block lateral surface and offers stepped hole the block lateral surface that gets rid of, and screw and elastic element are equipped in the stepped hole, the screw connects after passing through stepped hole with rotor, and the block that gets rid of is pressed on by elastic element on rotor.Centrifugal brake of the present invention, block is got rid of to be pressed on rotor outer circle circumferential surface by spring, the active force that block is thrown away and while rubbing with friction cylinder needs is got rid of by adjusting the precompression adjustment of spring, and then realize braking when torque adjustment, meet different operating modes, the raw brake request for choosing condition or operating conditions, the adjustment mode is simple, reliable, and to production, that life is brought is convenient.
Description
Technical field
The invention belongs in centrifugal brake field, more particularly, to centrifugal brake.
Background technology
Existing brake technical field, the adjustment of braking moment is that operator is adjusted by the size of applied force mostly
It is whole, it is difficult to be adjusted in itself to braking moment by machine driven system, therefore it is unsatisfactory for the demand of modern production.
Invention content
In view of this, the present invention is directed to propose centrifugal brake, according to the requirement of machine driven system, power when realizing braking
The adjustment of square.
In order to achieve the above objectives, the technical proposal of the invention is realized in this way：
Centrifugal brake, including the rotor being arranged concentrically in the friction cylinder being set on the base and the friction cylinder, described turn
It is equipped between son and friction cylinder and gets rid of block, the block lateral surface that gets rid of is the outer convex globoidal with friction cylinder inner wall face, this gets rid of block lateral surface
Stepped hole is offered, screw and elastic element are equipped in the stepped hole, the elastic element is set in the threaded shank of screw, described
Screw connects after passing through stepped hole with rotor, and the block that gets rid of is pressed on by elastic element on rotor.
Further, the number of blocks that gets rid of is four, this four are got rid of block and are evenly arranged on rotor circumference face.
Further, the ladder hole number for getting rid of block is two, and two stepped holes are axial arranged along block is got rid of.
Further, the block lateral surface that gets rid of is equipped with rub resistance material layer.
Further, the elastic element is spring.
Relative to the prior art, centrifugal brake of the present invention has the advantage that：
Centrifugal brake of the present invention gets rid of block and is pressed on rotor outer circle circumferential surface by spring, by adjusting spring
Precompression adjustment get rid of the active force that block throws away and needed when rub with friction cylinder, and then when realizing braking torque adjustment, expire
Foot difference operating mode, the raw brake request for choosing condition or operating conditions, the adjustment mode is simple, reliable, is brought just to production, life
It is prompt.

Connection inside two elements.For the ordinary skill in the art, above-mentioned term can be understood by concrete condition
Concrete meaning in the present invention.
The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
As shown in Figure 1, 2, centrifugal brake, including the rotor 5 being arranged concentrically in friction cylinder 1 and the friction cylinder 1, friction cylinder
1 is fixedly mounted on pedestal 7, in use, rotor 5 is mounted on the transmission shaft of equipment, transmission shaft drives rotor 5 to rotate, institute
It states and is set between rotor 5 and friction cylinder 1 there are four getting rid of block 2, this four are got rid of block 2 and are evenly arranged on 5 periphery of rotor, described in each
It is the outer convex globoidal with 1 inner wall face of friction cylinder to get rid of 2 lateral surface of block, and it is to be correspondingly arranged with 5 outer circumference surface of rotor to get rid of 2 medial surface of block
Inner concave arc surface, this gets rid of 2 lateral surface of block and offers stepped hole, and screw 4 and elastic element 3, the present embodiment are equipped in the stepped hole
In, the elastic element 3 is spring, and the elastic element 3 is set in the threaded shank of screw 4, after the screw 4 passes through stepped hole
It is connected with rotor 5, the block 2 that gets rid of is pressed on by elastic element 3 on rotor 5.When the drive of rotor 5 gets rid of block 2 together around 5 axis of rotor
Line rotates, and after rotating speed reaches certain value, gets rid of block 2 and is thrown out of, 1 medial surface friction of lateral surface and friction cylinder, to equipment system
It is dynamic, by adjusting the precompressed elastic force of elastic element 3, change torque size during braking.
In the present embodiment, the ladder hole number for getting rid of block 2 is two, and two stepped holes are axial arranged along block 2 is got rid of.
In the present embodiment, in order to ensure that braking reliability and raising are got rid of the block service life, 2 lateral surface of block that gets rid of is equipped with rub resistance
Material layer 6.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
With within principle, any modification, equivalent replacement, improvement and so on should all be included in the protection scope of the present invention god.
