According to the central sleeve structure, the two tapered roller bearings are used, so that the structure is simplified, the problems of installation difficulty and high manufacturing cost are effectively solved, and the assembly accuracy is improved; and the central sleeve structure is changed, and the central sleeve and the tray used for supporting the lifting seat are divided into two parts, so that the damage to the central sleeve is reduced.
Description
Technical field
The present invention relates to a kind of tube-in-tube structure, the cylindrical central sleeve structure on especially a kind of circular knitting machine belongs to technical field of textile machine.
Background technology
The cylindrical central sleeve structure of circular knitting machine as shown in Figure 1 in the prior art, holder a8 requires to be fixed in the cylindrical central sleeve 5a with three straight pin opsition dependents, radial ball bearing 2a is installed respectively at the upper and lower side two ends in cylindrical central sleeve 5a, after the radial ball bearing 2a that again central shaft 4a is up passed the lower end from the lower end puts in place, be pressed into the radial ball bearing 2a on top, install correlated parts, the lower end of central shaft 4a is connected with top cylinder seat 7a, and the upper end is the shaft extension end; On the top in the cylindrical central sleeve 5a outside lifter wheel 10a is installed again, installs retainer 3a at the middle part in the outside, in the bottom in the cylindrical central sleeve 5a outside elevating bracket 6a is installed, lifter wheel 10a is fixed on the retainer 3a by pressing plate 9a; At last install transmission gear wheel 1a at the shaft extension end of central shaft 4a, and lock with locking nut.
This complicated structure, two radial ball bearing 2a are difficult at axial locking, owing to the play of radial ball bearing 2a causes circular runout, have a strong impact on the precision of machine, need larger forcing press during assembling radial ball bearing 2a; Elevating bracket 6a need to change according to different types in addition, when changing, must pull down upper driving gear wheel 1a, screw out lifter wheel 10a, whole cylindrical central sleeve conjunction is taken out from retainer 3a, just can again change elevating bracket 6a, the so both useless power of useless worker, and affect original precision.On the other hand, the bottom of cylindrical central sleeve 5a of the prior art is provided with the boss 11a that protrudes from cylindrical central sleeve 5a surface, and this boss 11a and cylindrical central sleeve 5a are an integral body, is used for supporting elevation seat 6a, prevents that elevating bracket 6a from coming off; But this kind structure is in practical work process, and the pressure that boss 11a bears is larger, after boss 11a damages, need to carry out integral replacing to cylindrical central sleeve 5a.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, the structure of the cylindrical central sleeve on a kind of circular knitting machine is provided, simplify the structure, solved the installation hard problem, improved assembly precision.
According to technical scheme provided by the invention, cylindrical central sleeve structure on the described circular knitting machine, comprise cylindrical central sleeve, it is characterized in that: about described cylindrical central sleeve, in the endoporus at two ends taper roll bearing is installed respectively, the outer ring of taper roll bearing is connected with cylindrical central sleeve, mounting center axle in the inner ring of taper roll bearing, the upper end of central shaft are the shaft extension end; Outer upper at described cylindrical central sleeve is installed lifter wheel, outer middle side part at cylindrical central sleeve is installed retainer, in the outer lower portion of cylindrical central sleeve elevating bracket is installed, at the bottom of cylindrical central sleeve fixed tray, at the fixing upper driving gear wheel of the shaft extension end of described central shaft.
Described upper driving gear wheel is fixedly connected with central shaft by the connecting plate of central shaft shaft end.
Described lifter wheel is pressed on the retainer by pressing plate.
The bottom of described central shaft is connected with the top cylinder seat.
Cylindrical central sleeve structure of the present invention makes to simplify the structure by using two taper roll bearings instead, efficiently solves difficulty is installed, and cost of manufacture is high, has improved assembly precision; The present invention has changed the structure of cylindrical central sleeve, and cylindrical central sleeve and the pallet that is used for the supporting elevation seat are divided into two parts, has reduced the damage of cylindrical central sleeve.
Description of drawings
Fig. 1 is the structural representation of prior art cylindrical central sleeve.
Fig. 2 is structural representation of the present invention.
The specific embodiment
The invention will be further described below in conjunction with concrete accompanying drawing.
As shown in Figure 2: the cylindrical central sleeve structure on the described circular knitting machine comprises upper driving gear wheel 1, taper roll bearing 2, elevating bracket 3, central shaft 4, cylindrical central sleeve 5, elevating bracket 6, top cylinder seat 7, pallet 8, pressing plate 9, lifter wheel 10, connecting plate 11 etc.
As shown in Figure 2, the present invention includes cylindrical central sleeve 5, in the endoporus at the up and down two ends of cylindrical central sleeve 5 taper roll bearing 2 is installed respectively, the outer ring of taper roll bearing 2 is connected with cylindrical central sleeve 5, mounting center axle 4 in the inner ring of taper roll bearing 2, the upper end of central shaft 4 are the shaft extension end; Outer upper at described cylindrical central sleeve 5 is installed lifter wheel 10, at the outer middle side part of cylindrical central sleeve 5 retainer 3 is installed, and in the outer lower portion of cylindrical central sleeve 5 elevating bracket 6 is installed, at the bottom of cylindrical central sleeve 5 fixed tray 8, to prevent elevating bracket 6 landings; Described lifter wheel 10 is pressed on the retainer 3 by pressing plate 9; At the fixing upper driving gear wheel 1 of the shaft extension end of described central shaft 4, upper driving gear wheel 1 is fixedly connected with central shaft 4 by the connecting plate 11 of central shaft 4 shaft ends;
The bottom of described central shaft 4 is connected with top cylinder seat 7.
Installation process of the present invention: the outer ring of two taper roll bearings 2 is respectively charged in the endoporus of cylindrical central sleeve 5 upper ends and lower end, again the bearing cone of lower end taper roll bearing 2 is pressed into an end of central shaft 4, put oil sealing, central shaft 4 is up passed cylindrical central sleeve 5 from the lower end of cylindrical central sleeve 5, be pressed into the bearing cone of another taper roll bearing 2 from the upper end, it is rear locked and firm with the floor clip lock with locking nut to put in place again; Cylindrical central sleeve 5 sub-assemblies are passed elevating bracket 3, screw on lifter wheel 10 at cylindrical central sleeve 5, cover pressing plate 9, install transmission gear wheel 1 at the shaft extension end of central shaft 4 again, be connected fastening with central shaft 4 upper driving gear wheel 1 with connecting plate 11; From the lower end of cylindrical central sleeve 5 elevating bracket 6, pallet 8 and top cylinder seat 7 are installed at last.
