Abstract
The utility model discloses a rotor type open -end spinning machine's hold -in range tensioning adjustment mechanism, including tensioning swing arm, take -up pulley, bearing frame, the one end of tensioning swing arm is fixed with the bearing frame through swing arm clamping screw, and the take -up pulley passes through locking screw to be connected with the other end of tensioning swing arm, be provided with the spherical pad circle between locking screw and the tensioning swing arm, the spherical pad circle is connected with the tensioning swing arm through adjusting screw. The utility model discloses an increase a spherical pad circle between locking screw and tensioning swing arm to and set up adjusting screw and locking screw, and substituted present tensioning swing arm is cracked and band pulley clamping screw, has reduced the process of tensioning shaft, makes when adjustment hold -in range off tracking, and the setting obtains quantizing just easily making the hold -in range adjustment placed in the middle, and the damage of spare part reduces machine cost when avoiding some adjustment hold -in ranges, and the operation of messenger's machine is more reliable and more stable.
Description
Technical field
The utility model relates to governor motion, is specifically related to a kind of Timing Belt tensioning governor motion of rotor spinning machine.
Background technology
The installation of all Timing Belts on existing rotor spinning machine, all need to carry out tensioning and sideslip adjustment to Timing Belt, the tensioning of Timing Belt rotates realization by tensioning swing arm around bearing block, unscrew the screw of tensioning arm shaft bearing end, standard universal tool orientation turn tensioning swing arm is used to make it compress to Timing Belt, when Timing Belt reaches required tensile force, tighten pinching screw thus reach tensioning Timing Belt object; The sideslip adjustment of existing Timing Belt utilizes raising element precision and machine assembly precision to improve, but can not ensure not run band completely, or by conventional tool, tensioning swing arm distortion is adjusted.In such scheme, Timing Belt sideslip adjusts, there is certain defect: improve element precision and machine cost is improved, improve assembly precision and installation output is declined, overall machine cost is improved, use tensioning swing arm distortion adjustment, adjustment link can not get quantizing, and needs repeatedly to adjust also to ensure that each Timing Belt is placed in the middle, other parts of machine also can be made to bear extra destrabilizing moment during swing arm distortion, as drive bearing block etc., easily cause Timing Belt and other damage parts.
Utility model content
For problems of the prior art, the purpose of this utility model is to design the Timing Belt tensioning governor motion providing a kind of rotor spinning machine, and this Timing Belt tensioning governor motion is for solving existing Timing Belt adjustment difficulty and cannot quantizing to regulate, easily cause the problem of Timing Belt and other damage of components.
The Timing Belt tensioning governor motion of described rotor spinning machine, it is characterized in that comprising tensioning swing arm, regulating wheel, bearing block, one end of tensioning swing arm is fixed by swing arm pinching screw and bearing block, regulating wheel is connected by the other end of lock-screw with tensioning swing arm, be provided with spheric washer between described lock-screw and tensioning swing arm, described spheric washer is connected with tensioning swing arm by adjustment screw.
The Timing Belt tensioning governor motion of described rotor spinning machine, is characterized in that described spheric washer is hemispherical packing ring.
The Timing Belt tensioning governor motion of described rotor spinning machine, is characterized in that the radian of described spheric washer is SR15 ~ SR17.
The Timing Belt tensioning governor motion of described rotor spinning machine, it is characterized in that described adjustment screw globally packing ring circumference uniform distribution arrange.
The Timing Belt tensioning governor motion of described rotor spinning machine, is characterized in that being provided with back-up ring between described tensioning swing arm and bearing block.
The utility model by increasing a spheric washer between lock-screw and tensioning swing arm, and set up adjustment screw and lock-screw, replace existing tensioning swing arm to crack and belt wheel pinching screw, decrease the operation of tension wheel shaft, make when adjusting Timing Belt sideslip, adjustment amount is quantized and easily makes Timing Belt adjust between two parties, avoids the damage of parts during some adjustment Timing Belts, reduce machine cost, machine is run more reliable and more stable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1-tensioning swing arm, 2-regulating wheel, 3-bearing block, 4-swing arm pinching screw, 5-lock-screw, 6-spheric washer, 7-adjustment screw, 8-back-up ring.
Detailed description of the invention
The utility model is further illustrated below in conjunction with Figure of description.
As shown in Figure 1, the Timing Belt tensioning governor motion of the utility model rotor spinning machine, for the adjustment placed in the middle of Timing Belt, comprise tensioning swing arm 1, regulating wheel 2, bearing block 3, one end of tensioning swing arm 1 is fixed by swing arm pinching screw 4 and bearing block 3, regulating wheel 2 is connected with the other end of tensioning swing arm 1 by lock-screw 5, spheric washer 6 is provided with between lock-screw 5 and tensioning swing arm 1, this spheric washer 6 is hemispherical packing ring, the radian of spheric washer is SR15 ~ SR17, spheric washer 6 is connected with tensioning swing arm 1 by adjustment screw 7, adjustment screw 7 globally packing ring 6 circumference uniform distribution arrange, optimum is provided with 4, for fixed tensioning swing arm 1 is in the position of bearing block 3 axis, back-up ring 8 is provided with between tensioning swing arm 1 and bearing block 3.
The utility model regulating wheel 2 original state regulates by adjustment screw 7 gap that between regulating wheel 2 and tensioning swing arm 1,2mm spaces, lock-screw 5 allows regulating wheel 2 be fastened on one end of tensioning swing arm 1 by spheric washer 6, the other end back-up ring 8 of tensioning swing arm 1 limits tensioning swing arm 1 at bearing block 3 axial location, with swing arm pinching screw 4, tensioning swing arm 1 is fixed clampingly to tensioning position of synchronous belt; When Timing Belt sideslip, the first slight lock-screw 5 loosened on regulating wheel 2, then by the equally distributed adjustment screw 7 of regulating circumferential, make regulating wheel 2 axial line produce the angle change of 0 °-5 ° at different cross section, as wished, adjusting angle excursion increases or reduces, the gap of spacing between adjustable regulating wheel 2 and tensioning swing arm 1, thus the sideslip of adjustment Timing Belt, make Timing Belt placed in the middle and be in the state of operating steadily, finally tighten lock-screw 5, adjustment completes.This governor motion, simple to operate, degree of regulation is high, is convenient to implement.
