Abstract
The present invention relates to a single rotation key clutch which is composed of a middle sleeve 1, a single rotation key 3 and a control mechanism 6. The present invention is characterized in that a half-moon gap between the middle sleeve and a shaft, and the middle sleeve 1, the shaft 2 and the single rotation key is stuffed with a half-moon matching key 7 of which the shape and the size are the same as those of the half-moon gap so as to eliminate the half-moon gap; thereby, the present invention prevents the shaft 2 from generating advanced rotation, eliminates impact and noise which result from the advanced rotation, and thus, does not need a constant brake band type brake, and is favorable for matching slight-movement moulds for mechanical pressing machines; compared with a double rotation key clutch, the present invention has the advantages of simple structure and low manufacture cost.
Description
The invention belongs to the Clutch Technology field, be specifically related to a kind of Clotch with single rotating key.
The Clotch with single rotating key of using is made up of middle cover, single turn key and operating mechanism at present, when manipulation mechanism, single turn key is in makes on middle cover and axle idle running or the coupled position, reaches the clutch purpose.At present, this clutch is widely used on the following mechanical press of 100T.But this clutch exists two shortcomings: promptly (1) just makes axle under extraneous power effect owing to there is the space to exist between middle cover and single turn key, may produce leading rotation, thereby causes impact and noise.In order to prevent leading rotation, the band brake of a normal braking of normal preparation provides a frictional resistance moment in the practice, to stop axle to produce leading rotation, but so, many idle works had both been consumed, also increased the wearing and tearing of clamping strap, particularly when mechanical press is in automatically continuously the punching press operating mode, clamping strap can be very fast can not be worked because of excessive heating.(2) use the mechanical press of rotating key clutch, all adopt the method for manual jiggering to carry out adjusting microinching mould, and when using Clotch with single rotating key, the setting stick flywheel is beaten ahead running, and slide block descends, during reverse-starting braking operation, slide block can not rise thereupon, and this just makes troubles to mould to adjusting microinching.Adopt two rotating key clutches can solve above-mentioned two problems, but two rotating key clutch complex structure, machining amount is big, and requirement on machining accuracy is high, makes the device fabrication expense increase.
The object of the invention provides a kind of Clotch with single rotating key of new structure, can eliminate the above-mentioned shortcoming that prior art exists effectively.
The present invention seeks to realize like this: the present invention is made up of middle cover, single turn key and operating mechanism, it is characterized in that middle cover and axle and in cover and spool and single turn key between in several semilune spaces of forming, fill in shape, big or small identical, and be that the semilune that is slidingly matched is joined key with the semilune space.
Advantage of the present invention and good effect:
(1) owing to adopted semilune to join key, eliminates the space between middle cover and axle and middle cover and axle and the single turn key, also just avoided axle to produce the possibility of rotation in advance.In the time of on being applied to mechanical press, also need not often to have braked band brake.
Adjusting microinching is to mould when (2) helping using on mechanical press.
(3) compare with two rotating key clutches, simple in structure, low cost of manufacture.
Description of drawings:
Fig. 1 is a prior art Clotch with single rotating key structural drawing.
Fig. 2 is an a-a sectional view among Fig. 1.
Fig. 3 is a Clotch with single rotating key structural drawing of the present invention.
Fig. 4 is an a-a sectional view among Fig. 3.
Among the figure: the single turn key 4-of cover 2-axle 3-space among the 1-
5-belt pulley and middle cover 1 sense of rotation 6-operating mechanism 7-semilune are joined key
Embodiment's explanation:
As shown in Figure 2, be sleeved on the end of axle 2 by key and the joining middle cover 1 of mechanical press belt pulley, middle with single turn key 3 connections, middle cover 1 and axle 2 and in several semilune spaces of formation between cover 1 and axle 2 and the single turn key 3, fill in shape, big or small identical, and be that the semilune that is slidingly matched is joined key 7 with the semilune space, like this, belt pulley has just been eliminated axle 2 and has been produced the possibility of leading rotation, and be convenient to adjusting microinching to mould by Clotch with single rotating key transmission of the present invention.
Claims (1)
