Description

The harmless damping device of sense square

Technical field

The utility model relates to a kind of mechanical transmission braking device, and more particularly it is a kind of harmless damping device of sense square that moves according to torque and velocity variations.

Background technique

The mode that mechanical transmission braking is at present extensively adopted has: mechanical force braking, hydraulic pressure or air braking, electromagnetic force braking.These modes of braking all need comparatively complicated peripheral hardware control mechanism and drive the power source of actuator.Also must complicated control loop feedback mechanism to the occasion of automatically control, thereby cause complex structure, the manufacture cost height, maintaining requires shortcomings such as numerous and diverse.And these arrestment mechanisms have wearing and tearing and aging (electricity piece) phenomenon because of reasons in structure in long-time running, thereby guarantee to improve improvement for the reliability that is applied to continuously uninterrupted (24 hours) running state.

Summary of the invention

The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art part, and provides a kind of sense square to can't harm damping device.This device has improved functional reliability, has reduced manufacture cost and maintaining requirement; Structure is simple relatively simultaneously, need not the peripheral hardware control mechanism.

The purpose of this utility model realizes by following proposal: the harmless damping device of sense square, it is made up of brake disc 1, rotor 2, damper 3, torque adjusting mechanism 4, protective housing 5, wherein brake disc 1 is loaded on the body fixed position, point of action as damping torque, damper 3 is connected on the rotor 2, rotor 2 is loaded on the running shaft, and torque adjusting mechanism 4 is contained in an end of damper 3, and protective housing 5 is solidly fixed with brake disc 1 and occupy peripheral.

The purpose of this utility model also can realize by following proposal: a kind of sense square can't harm damping device, is connected by hinging shaft 6 between wherein said damper 3 and the rotor 2.

Or wherein said damper 3 is structure as a whole with rotor 2.

Wherein said damper 3 is the damping fork.

Or described rotor 2 is star-like damping rotor.

The utility model is compared with existing arrestment mechanism and had the following advantages: it is simple in structure 1. to feel the harmless damping device of square, and the number of components is few, and low cost of manufacture has reduced the maintaining requirement.2. need not peripheral controller, realize just that by automatic identification moment size and rotating speed the damping action controls automatically.3. long-term the use do not have wearing and tearing, satisfied the working condition of continuous long-time running in 24 hours fully; As there not being the relative movement part when the damping brake state, and moving parts and retaining element are in contactless state when discharging operation.

Description of drawings

Fig. 1 is an embodiment of the present utility model (swing link type sense square can't harm a damping device) structural representation;

Fig. 2 is another embodiment of the present utility model (star-like formula sense square can't harm damping device) structural representation.

Embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail.

In Fig. 1, Fig. 2: 1-brake disc, 2-rotor, 3-damper, 4-torque adjusting mechanism, 5-protective housing, 6-hinging shaft.

Operating principle of the present utility model is: utilize the variation of rotor level of torque to make damping member action or static, and the velocity variations of running makes damping member change to the relative position of brake disc, reach damping brake or disengage the release damping, be in the non-contact running state.

During the harmless damping device work of sense square, the running shaft moment that is connected when itself and rotor 2 than hour, overcome frictional force between damper 3 and the brake disc 1 thereby the damped braking of running shaft because of enough running torques can not be arranged.When and the running shaft moment that is connected of rotor 2 when becomeing greater to above the frictional force between damper 3 and the brake disc 1, relative contact-sliding appears between rotor 2 and the brake disc 1, the damping brake state is disengaged.When rotary shaft rotating speed further is increased to a certain value, the centrifugal force that rotation produces makes damper 3 distortion disengagings change into contactless state with contacting of brake disc 1, make the rotation of the harmless damping device of sense square not have wearing and tearing fully, thereby realize controlling damping automatically or removing damping with rotor torque and velocity variations.

The harmless damping device of sense square has designed torque adjusting mechanism 4, thereby it is to utilize Regulation spring the pressure of damper to be changed the adjusting of the size realization moment of the frictional force between damper 3 and the brake disc 1.When spring pressure hour, the frictional force between damper 3 and the brake disc 1 is less.When spring pressure is transferred when big, it is big that the frictional force between damper 3 and the brake disc 1 becomes.And damper 3 to be subjected to the action of centrifugal force size be corresponding with rotational speed, constant, so change the size that frictional force has just changed damping torque.

In sum, the utility model has utilized original moment and rotary centrifugal force organically in conjunction with forming control damping automatically or removing damping.Efficiently solve the senile abrasion problem of former peripheral hardware control type brake structural complexity and long-time running.

Need to prove to those of ordinary skill in the art: under the situation of not violating the utility model principle, can also make some improvement and distortion to the utility model, this belongs to protection domain of the present utility model equally.
