Abstract
The utility model discloses a displacement adjusting device, in particular a compression roller displacement adjusting device. The adjustment precision of the compression roller displacement adjusting device is improved. The compression roller displacement adjusting device comprises a motor, a worm-gear case, a driving nut, a screw rod, a distance adjusting screw nut and a mounting shell, wherein the worm-gear case is connected with the motor; the driving nut is fixedly connected to a worm gear and is in mounting fit with the screw rod through screw threads; the worm gear in the worm-gear case, the driving nut and the screw rod are coaxially arranged; the distance adjusting screw nut is arranged on the screw rod in a matching way through screw threads and is fixedly connected with the worm gear; and the mounting shell is sleeved on the distance adjusting screw nut and is dynamically matched with the distance adjusting screw nut. Through the distance adjusting screw nut, the screw rod and the driving nut are tightly fitted by screwing the distance adjusting screw nut when the screw rod and the driving nut are loosened, so clearances are reduced during transmission, and distance adjustment is more precise.
Description
Technical field
The utility model relates to a kind of displacement adjustment device, especially a kind of pressure roller displacement adjustment device.
Background technology
When using calender, owing to need the product to different-thickness, therefore the spacing between common two pressure rollers is adjustable.In the adjustment process of roller space, utilize worm gear, worm screw to drive nut and rotate, and then make the screw mandrel advance and retreat drive the bearing block advance and retreat.Be actually through screw thread and carry out transmission, owing to relatively have certain clearance between screw mandrel and the nut, therefore be in course of adjustment, the drive gap of screw mandrel and nut can't be adjusted control, causes error.Be difficult to reach desired roll spacing spacing precision, can't guarantee the requirement of film thickness deviation.
The utility model content
The utility model technical problem to be solved provides a kind of pressure roller displacement adjustment device that improves the adjustment precision.
The utility model solves the pressure roller displacement adjustment device that its technical problem adopted; Comprise motor, the worm gear case that links to each other with motor, transmission nut and screw mandrel; Said transmission nut is fixedly connected on the said worm gear, and said transmission nut is installed through screw thread with said screw mandrel and cooperated all coaxial setting of the worm gear in the said worm gear case, said transmission nut and said screw mandrel; Also comprise adjusting screw nut and mounting shell; Said adjusting screw nut is installed through screw thread and is engaged on the said screw mandrel, and said adjusting screw nut is fixedly connected with said worm gear, said mounting shell be set on the said adjusting screw nut and with said adjusting screw nut movingly.
Further be, also comprise apposed seats, said apposed seats be set in said screw mandrel afterbody and with said screw mandrel movingly.
Further be that said adjusting screw nut is connected through key with said worm gear.
Further be that said mounting shell is installed through bearing with adjusting screw nut and cooperated.
The beneficial effect of the utility model is: through adjusting screw nut is set; Can when screw mandrel and transmission nut are loosening, tighten adjusting screw nut; Make screw mandrel cooperate with transmission nut closely; This has just caused and in transmission, has reduced the gap, makes roll adjustment more accurate, and the calendering product of producing like this is also more accurate.Afterbody at screw mandrel can also be provided with apposed seats, thereby prevents that screw mandrel from circumferentially rocking when transmission, thereby guarantees the accuracy of adjusting.Adjusting screw nut can also accessory drives be given screw mandrel, thereby better guarantees transmission stability.
Description of drawings
Fig. 1 is the front view of the utility model;
Fig. 2 is the vertical view of the utility model;
Parts, position and numbering among the figure: motor 1, worm gear 2, transmission nut 3, screw mandrel 4, adjusting screw nut 5, mounting shell 6, apposed seats 7, key 8, worm gear case 9.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Like Fig. 1, shown in Figure 2; The utility model comprises motor 1, the worm gear case 9 that links to each other with motor 1, transmission nut 3 and screw mandrel 4; Said transmission nut 3 is fixedly connected on the worm gear 2 of said worm gear case 9, and said transmission nut 3 and said screw mandrel 4 are installed through screw thread and cooperated, said worm gear 2, said transmission nut 3 and all coaxial setting of said screw mandrel 4; Also comprise adjusting screw nut 5 and mounting shell 6; Said adjusting screw nut 5 is installed through screw thread and is engaged on the said screw mandrel 4, and said adjusting screw nut 5 is fixedly connected with said worm gear 2, said adjusting screw nut 5 and said mounting shell 6 be set on the said adjusting screw nut 5 and with said adjusting screw nut 5 movingly.In use, motor 1 drives worm gear case 9 and rotates, thereby is converted into worm gear 2 rotations; Because transmission nut 3 is fixedly connected on the worm gear 2, so transmission nut 3 also does identical rotatablely moving, and transmission nut 3 is through being threaded with screw mandrel 4; Therefore as long as transmission nut 3 forward or reverse can make screw mandrel 4 advance and retreat; Regulate worm gear case 9 and can make worm gear 2 forward or reverse, the gearratio of each parts is pressed the actual needs setting, to reach the accuracy of screw mandrel 4 forward travels.Owing to also be provided with adjusting screw nut 5 on the screw mandrel 4; Adjusting nut 5 can hold out against or loosen screw mandrel 4; Therefore the degree of tightness that controls to adjust nut 5 is a scalable screw mandrel 4 and the tight ness rating that cooperates of transmission nut 3; Thereby effectively control transmission accuracy, so just make that the gap between two rollers is more accurate in calender line, the product quality of producing is also better.Since adjusting nut 5 be with mounting shell 6 movingly; And adjusting nut 5 is to be fixedly connected with worm gear 2; Therefore adjusting nut 5 is done identical rotatablely moving with worm gear 2, transmission nut 3; Therefore adjusting nut 5 can not hinder the motion of screw mandrel, the transmission that in fact adjusting nut 5 can also assist, thus improve the accuracy of transmission.
In order to prevent that screw mandrel 4 from rocking, as shown in Figure 1, also comprise apposed seats 7, said apposed seats 7 be set in said screw mandrel 4 afterbody and with said screw mandrel 4 movingly.The afterbody of screw mandrel 4 is an opposite end of screw mandrel 4 ejection parts.Apposed seats 7 does not limit the axially-movable and the rotation of screw mandrel 4, only prevents that it from rocking, and in the process of screw mandrel 4 advance and retreat, has just avoided rocking like this, and this makes more stable to the roll adjustment of pressure roller, has guaranteed the quality of product.
For the ease of installing.As shown in Figure 1, adjusting screw nut 5 is connected through key 8 with said worm gear 2.Just more convenient at dismounting adjusting screw nut 5 like this, and transmission is also reliable.
Concrete, as shown in Figure 1, mounting shell 6 is installed through bearing with adjusting screw nut 5 and is cooperated.Utilize bearing can reduce resistance, reduce the frictional resistance of extra generation because adjusting screw nut 5 is installed.
