Abstract
The utility model provides a pull-type chain wheel regulating device. Due to the tensile stress borne by a regulating device, on the condition that a lock nut is loosened, a tensioning chain wheel is still restrained, after being locked, the position of the tensioning chain wheel maintains unchanged, and therefore the pull-type chain wheel regulating device is convenient to regulate, good in regularity, not prone to resonance and the like. The pull-type chain wheel regulating device comprises a machine frame. The machine frame comprises a ball chain, a chain wheel shaft and the tensioning chain wheel. The ball chain is sleeved on the tensioning chain wheel which is sleeved on the chain wheel shaft, and the machine frame is provided with the regulating device.
Description
Technical field
The utility model relates to logistics machine design and manufacturing technology field, is specially a kind of pull-type sprocket wheel control apparatus.
Background technology
Use the ball chain transmission device on the logistics load transfer device widely, generally, its tension wheel is taked to regulate tension wheel from the interior mode on top outward, makes ball chain keep certain predetermincd tension, the compression effort that control apparatus bears.When the chain bearing load, control apparatus can produce corresponding elastic deformation, makes the complicated variation that deflects or the like of the shaft core line of sprocket wheel.If the load of the variation that chain bears then is prone to take place resonance effect.In addition, under the situation of unclamping jam nut, the position of idler sprocket is unfettered, and is dilapidated, and after the locking, the position of idler sprocket is uncertain again, so adjustment is inconvenient.Be difficult to guarantee the tram and the attitude of sprocket wheel, thereby cause the sprocket wheel deflection, serious wear, mechanism's life-span is short.
Summary of the invention
To the problems referred to above, the utility model provides a kind of pull-type sprocket wheel control apparatus, the tensile stress that control apparatus is born; Under the situation of unclamping jam nut, idler sprocket still is tied, after the locking; The position of idler sprocket remains unchanged; So easy to adjust, it is good to have systematicness, be difficult for producing characteristics such as resonance.
Its technical scheme is such: it comprises frame; Include ball chain, sprocket shaft, idler sprocket on the said frame; Said ball chain is socketed on the said idler sprocket, and said idler sprocket is sleeved on the said sprocket shaft, it is characterized in that: on the said frame control apparatus is housed.
It is further characterized in that: said control apparatus comprises support, chain wheel support, regulates bolt; Said chain wheel support has two; Said adjusting bolted connection is between said chain wheel support; Said chain wheel support correspondence is installed in said sprocket shaft center, and said support is fixed on the said chain wheel support, fixes through the clamp nut on the said adjusting bolt near the chain wheel support of said idler sprocket one end; The support two ends of said other end chain wheel support are provided with setting nut, jam nut, and the chain wheel support of the said other end is fixed by bolt of rear end plate.
The utility model is being socketed with the sprocket shaft outside device for installing and adjusting of ball chain, and the chain wheel support at sprocket shaft place is fixed by clamp nut, and the chain wheel support of the other end is fixed by bolt of rear end plate, jam nut; Reduced the resonance power in the generation of chain bearing load, unclamped under the situation of jam nut simultaneously, idler sprocket still can be tied; After the locking; The position of idler sprocket remains unchanged, and adjusts also more conveniently, and has prolonged the service life of entire mechanism.
Description of drawings
Fig. 1 is the prior art constructions scheme drawing;
Fig. 2 is the structural representation of the utility model;
Fig. 3 is the birds-eye view of the utility model.
The specific embodiment
Like Fig. 2, shown in Figure 3, the utility model comprises frame 1, includes ball chain 5, sprocket shaft 6, idler sprocket 7 on the frame 1; Ball chain 5 is socketed on the idler sprocket 7, and idler sprocket 7 is sleeved on the sprocket shaft 6, on the frame 1 control apparatus is housed; Control apparatus comprises support 2, chain wheel support 4, regulates bolt 8; Chain wheel support 4 has two, regulates bolt 8 and is connected 4 of chain wheel supports, and chain wheel support 4 correspondences are installed in sprocket shaft 6 centers; Support 2 is fixed on the chain wheel support 4; Chain wheel support 4 near idler sprocket 7 one ends is fixing through the clamp nut of regulating on the bolt 89, and support 2 two ends of other end chain wheel support 4 are provided with setting nut 8, jam nut 10, and the chain wheel support 4 of the other end is fixed by bolt of rear end plate 11.
The chain wheel support 4 at sprocket shaft 6 places is fixed by clamp nut 9, and the chain wheel support 4 of the other end is fixed by bolt of rear end plate 11, jam nut 10, has reduced the resonance power that takes place at the chain bearing load; Simultaneously under the situation of unclamping jam nut 10; Idler sprocket 7 still can be tied, and after the locking, the position of idler sprocket 7 remains unchanged; Adjust also more conveniently, and prolonged the service life of entire mechanism.
1. frames among the figure; 2. support; 3. setting nut; 4. chain wheel support; 5. ball chain; 6. sprocket shaft; 7. idler sprocket; 8. adjusting bolt; 9. clamp nut; 10. jam nut; 11. bolt of rear end plate; 12. captive nut.
