Abstract
Double end retarder, relate to acupuncture nonwoven device-specific and promote the construction applications such as retarder, comprise housing, the one end in housing is wholely set two clutch shaft bearing seats, be bolted end cap at the other end of housing, be wholely set two the second bearing supports in the inner side of end cap; Two worm gears are set in housing, one end of each worm gear is all supported in corresponding clutch shaft bearing seat by clutch shaft bearing, the other end of each worm gear all by the second bearings in corresponding second bearing support, a worm screw of longitudinally arranging is placed in housing, worm screw is arranged between two worm gears, and two worm gears are all meshed with worm screw.During use, double end retarder is arranged on the below of holder web plate, a worm screw rotates drive two worm gear wheel, and the utility model adopts a worm screw to join two worm gears, and such structure can save cost more, and improve precision, structure is more compact.Select for the single kind of drive in the past provides another.
Description
Technical field
The utility model relates to acupuncture nonwoven device-specific and promotes the construction applications such as retarder.
Background technique
Needing machine is used for intensive acupuncture multi-layer fiber cloth and prepares high-performance fiber goods, existing non-weaving cloth needing machine, the height regulating mechanism of its holder web plate and stripping web plate mostly takes the technical pattern such as traditional jack type or conventional feed screw nut formula, there is transmission stability difference, also Worm and worm-wheel gearing is had, general is all that a worm screw joins a worm gear, due to unreasonable structure, makes cost high.
Model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides the double end retarder that a kind of cost is low.
The purpose of this utility model is achieved in that double end retarder, comprises housing, and the one end in housing is wholely set two clutch shaft bearing seats, is bolted end cap at the other end of housing, is wholely set two the second bearing supports in the inner side of end cap; Two worm gears are set in described housing, one end of each worm gear is all supported in corresponding clutch shaft bearing seat by clutch shaft bearing, the other end of each worm gear all by the second bearings in corresponding second bearing support, a worm screw of longitudinally arranging is placed in housing, worm screw is arranged between two worm gears, and two worm gears are all meshed with worm screw.
During use, double end retarder is arranged on the below of holder web plate, a worm screw rotates drive two worm gear wheel, and the utility model adopts a worm screw to join two worm gears, and such structure can save cost more, and improve precision, structure is more compact.Select for the single kind of drive in the past provides another, the utility model is applicable to gearing down field and needs the occasion of lifting.
In order to the power of worm and gear is transferred to holder web plate, in described housing, also place two screw mandrels vertically arranged, two worm gears are all threaded on corresponding screw mandrel, and one end of two rhizoid bars all passes end cap.
In order to increase supporting surface, make to support more firm, connect more convenient, one end that two rhizoid bars pass end cap is all threaded and supports parallels and fixed by junction of the edges of two sheets of paper screw.
In order to prevent dust from entering in housing, between two rhizoid bars and end cap, all seal ring is set.
Equal threaded coupling nut on two rhizoid bars in housing of the present utility model, each nut all by the 3rd bearings in corresponding second bearing support, nut has the function of tensioning.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is the plan view of Fig. 1.
Fig. 3 is the side view of Fig. 1.
Embodiment
As Figure 1-3, double end retarder, comprises housing 1, and the bottom in housing 1 is wholely set two steps 2, connects upper end cap 14 in the upper end of housing 1 by bolt 10, is wholely set two upper bearing brackets 7 in the inner side of upper end cap 14.
In housing 1, place a worm screw 6 of longitudinally arranging and two screw mandrels 4 vertically arranged, worm screw 6 is arranged between two rhizoid bars 4.The upper end of two rhizoid bars 4 is all passed upper end cap 14 rear thread and connects support parallels 12 and fixed by junction of the edges of two sheets of paper screw 11, all arranges seal ring 15 between two rhizoid bars 4 and upper end cap 14.Two rhizoid bars 4 in housing 1 are all threaded worm gear 5 and nut 13, two worm gears 5 are all meshed with worm screw 6, each worm gear 5 is all arranged on the below of corresponding nut 13, the lower end of each worm gear 5 is all supported in corresponding step 2 by lower bearing 3, the lower end of the nut 13 on the same filament bar 4 and the upper end of worm gear 5 are all supported in corresponding upper bearing bracket 7 by intermediate bearing 8, and the upper end of each nut 13 is all supported in corresponding upper bearing bracket 7 by upper bearing (metal) 9.
