Abstract
The utility model belongs to a design of foundation parts in the mechanical design, which is composed of an external embrace block braking mechanism which is overrode to a clutch mechanism and a spring tight brake. The utility model is characterized in that the external embrace block can tightly brake a brake wheel all along, a pusher dog and a star wheel are respectively served as an input port and an output port of the power, and the braking wheel is served as an external ring of the override mechanism. The utility model is mainly used for braking a crane, when the electric motor is starting, the pusher dog of the override clutch mechanism can drive the star wheel to rotate, and the star wheel can be separated with the braking mechanism. When the electric motor stops rotating, the gravity of the suspended object can be acted on the star wheel, so the brake wheel can be wedged and locked with the brake wheel, and the brake wheel can create braking with the action of the spring force.
Description
The utility model belongs to the design of basic parts in the machine design, and it is combined by the overrunning clutch mechanism of band pusher dog and outer armful of piece stop mechanism of the tight lock of spring.
In equipment such as lifting transportation, extensively adopt the outer block brake of embracing.And mostly be normally closed.Usually with spring or the tight lock of weight, when electric motor starting, the electromagnet by series connection with it declutches automatically.In the course of the work, electromagnet starts frequent.Not only power consumption, and coil very easily damages, and maintenance load is big.In addition, adopt worm gear pair mechanism to brake in addition.The shortcoming of this mechanism is that efficient is lower.
The purpose of this utility model is that a kind of improved crane braking device will be provided, and it can save the magnet coil part of outer armful of block brake of common employing.
The purpose of this utility model is achieved in that the outer shroud of overrunning clutch mechanism of band pusher dog makes the outer brake wheel of embracing the piece stop mechanism simultaneously, and this intermediate link of outer shroud (brake wheel) (5) connects into a new brake equipment with overrunning clutch mechanism and stop mechanism.The utility model adopts spring to make the outer piece of embracing all the time to the tight lock of brake wheel, and when electric motor starting, the pusher dog of overrunning clutch mechanism drives the star-wheel rotation, and star-wheel and stop mechanism are thrown off; When motor stopped, the lifted weight action of gravity made star-wheel and the locking of brake wheel wedging in star-wheel, thus braking.
The utility model comprises pusher dog (1), roller (2), star-wheel (3), spring (4), brake wheel (5), slipper (6), support (7) (referring to the entire bracket system) and spring (8).Pusher dog (1) is made the motion input end.Star-wheel (3) is made the motion mouth.Brake wheel (5) is made the outer shroud of overrunning clutch mechanism simultaneously.Spring (8) passes through slipper (6) all the time to the tight lock of brake wheel (5).
The utility model is compared with magnet stopper, has energy savings, simplified structure, advantage easy to maintenance; Compare raising rotational efficiency about 15～20% with the mechanism of worm gear pair braking.Braking of the present utility model is steering unit specially.
Engaging and disengaging gear of the present utility model generally adopts unidirectional roller to surmount type, and the wedging face of star-wheel (3) is the plane.This structure processing and manufacturing is simpler.When driven by motor mechanism clickwise, for roller (2) is unlikely friction appears on the surface that is extruded into outer shroud (5).Star-wheel (3) is made identical arc surface with the face of joint of roller (2).And tangent with the wedging plane on the star-wheel (3), so both reduced contact stress, brought convenience to processing again.The design at the wedging angle of roller (2) answers Bao Zheng mechanism to throw off easily, and being unlikely again can not wedging.After using a period of time, the angle of wedge increases.The replacing roller gets final product.The external part of spring (4) can be put into small column.So that spring is correctly flexible.
Claims (1)
- A kind of drg.Have: the stop mechanism that the overrunning clutch mechanism of being made up of pusher dog [1], roller [2], star-wheel [3], spring [4], outer shroud [5] and brake wheel [5], slipper [6], support [7], spring [8] are formed.Of the present utility model being characterised in that: the outer shroud of overrunning clutch mechanism is exactly the brake wheel of stop mechanism.
